Description

Digital real security system and method

Technical Field

The present invention relates to a digital real security system, method, and program that allow reporting of a security abnormal situation even in the presence of a suspicious person without being recognized by the suspicious person.

Background

Service operations such as stores including department stores, supermarkets and convenience stores, banks, corporate offices, factories, event halls, terminal buildings, currency exchanges, cash carriers, buses, and taxis have been processing financial instruments, cash, and/or merchandise. Their customers include not only benevolent persons but also those with criminal intentions, and thus there is a high risk of criminal damage along with operational activities.

In an emergency situation, it is common for a victim to notify his/her family, company-related people, police, etc. of the emergency and wait for help. However, victims threatened by a perpetrator are restricted from doing any action, which in many cases results in trouble or accidents.

In the past, as an apparatus that performs transmission of an emergency signal without being able to move freely, there has been provided an apparatus that is fitted to a belt of a user and performs transmission based on sensing a change in tension on the belt when the user tightens his/her abdomen.

Patent document 1 describes an emergency transmitter that transmits an emergency signal by a user applying his/her abdominal pressure, the emergency transmitter including a pressure detecting unit for detecting the pressure applied to a contact surface, a transmitting unit for transmitting the emergency signal, and a control unit for causing the transmitting unit to transmit the emergency signal therefrom when it is determined that it is abnormal based on an output of the pressure detecting unit. The emergency transmitter described in patent document 1 transmits an emergency signal based on, for example, a convenience store clerk or a bank clerk tightening his/her abdomen even without being able to move freely.

In order to prevent an erroneous report and a failure report caused by belt tightness adjustment or the like, the emergency transmitter described in patent document 1 adopts a configuration further including a cancel switch to determine that it is abnormal unless a cancel signal is input within a predetermined time.

However, even if such a cancel switch is provided, all of the error reports and the failure reports cannot be prevented. That is, since the emergency transmitter described in patent document 1 maintains a structure that senses the abdominal pressure of the user to determine an abnormality, when the signal itself, which is to sense the abdominal pressure, contains noise associated with breathing, the magnitude and timing of the abdominal pressure may be erroneously detected due to the noise.

[ problem ] to

In addition, the emergency transmitter described in patent document 1 does not assume with certainty that a riot robbes the user of the apparatus. In this case, if a rioter leaves the apparatus as it is, there is a possibility that the occurrence of an abnormality can be sensed by judging a situation such as lack of response to a periodic transmission or a call. However, there has been a problem of lack of real-time performance in time-sensitive situations. Moreover, when a rioter knows the mechanism of the device and wears it on him/herself or a third person without leaving, it is difficult to detect the occurrence of an abnormal situation.

An object of the present invention is to provide a digital realistic security system, method, and program that allow reliable reporting of the occurrence of an emergency situation in real time.

[ solution to problem ]

The digital real security system according to the present invention comprises: abdominal pressure signal acquisition means for acquiring an abdominal pressure signal from an abdominal pressure sensor for detecting an abdominal pressure of a person to whom the abdominal pressure sensor is fitted; abdominal pressure signal extraction means for extracting an abdominal pressure pattern in which abdominal pressure changes and/or a number of breaths per unit time from the acquired abdominal pressure signal; a storage means for storing the abdominal pressure pattern and/or the number of breaths of the person at a normal time extracted by the abdominal pressure signal extraction means in association with the person; abnormality determination means for matching the abdominal pressure pattern and/or the number of breaths extracted by the abdominal pressure signal extraction means with the abdominal pressure pattern and/or the number of breaths of the person at a normal time stored in the storage means and determining whether or not it is abnormal based on the matching result; and a control device for reporting an abnormal situation based on an abnormality determination result of the abnormality determining device.

Also, the abdominal pressure signal extraction means subtracts the breathing signal component from the acquired abdominal pressure signal, and extracts the abdominal pressure pattern in which the influence of breathing is suppressed from the abdominal pressure signal, which allows accurate determination of the intentional abnormality of the person.

Also, if the matching result of the abdominal pressure pattern and/or the number of breaths extracted by the abdominal pressure signal extraction means with the abdominal pressure pattern and/or the number of breaths of the person at the time of normality stored in the storage means is a mismatch, the abnormality determination means determines that it is an abnormality, which enables matching verification to be performed even when the user of the chest/abdominal motion signal detection apparatus 300 is hijacked and put on the apparatus to allow an abnormal situation to be determined, thereby allowing an abnormal situation to be reported.

Also, the control means makes different reports according to the abnormality determination result of the abnormality determining means, which allows detailed reports to be made according to the details or degree of the abnormal situation.

Also, the reporting apparatus transmits an email message and an image, which allows a person who receives the report to accurately and quickly evaluate an abnormal situation.

The digital real security method comprises the following steps: an abdominal pressure signal acquisition step of acquiring an abdominal pressure signal from an abdominal pressure sensor for detecting an abdominal pressure of a person to whom the abdominal pressure sensor is attached; an abdominal pressure signal extraction step of extracting an abdominal pressure pattern in which abdominal pressure changes and/or the number of breaths per unit time from the acquired abdominal pressure signal; a storage step of storing the abdominal pressure pattern and/or the number of breaths of the person at a normal time extracted by the abdominal pressure signal extraction step in association with the person; an abnormality determination step of matching the abdominal pressure pattern and/or the number of breaths extracted by the abdominal pressure signal extraction step with the abdominal pressure pattern and/or the number of breaths of the person at normal times stored by the storage step, and determining whether or not it is abnormal based on a matching result; and a control step of reporting an abnormal situation according to the abnormal determination result of the abnormal determination step.

The present invention is also a program for causing a computer to function as a digital real security system including: abdominal pressure signal acquisition means for acquiring an abdominal pressure signal from an abdominal pressure sensor for detecting an abdominal pressure of a person to whom the abdominal pressure sensor is fitted; abdominal pressure signal extraction means for extracting an abdominal pressure pattern in which abdominal pressure changes and/or a number of breaths per unit time from the acquired abdominal pressure signal; a storage means for storing the abdominal pressure pattern and/or the number of breaths of the person at a normal time extracted by the abdominal pressure signal extraction means in association with the person; abnormality determination means for matching the abdominal pressure pattern and/or the number of breaths extracted by the abdominal pressure signal extraction means with the abdominal pressure pattern and/or the number of breaths of the person at a normal time stored in the storage means and determining whether or not it is abnormal based on the matching result; and a control device for reporting an abnormal situation based on an abnormality determination result of the abnormality determining device.

[ advantageous effects of the invention ]

The present invention allows reliable reporting of the occurrence of an emergency in real time. The present invention allows reporting of abnormal situations even when a rioter hijacks the user of the sensor and wears the sensor.

Detailed Description

Hereinafter, modes for carrying out the present invention will be described in detail with reference to the accompanying drawings.

(first embodiment)

Fig. 1 is a block diagram showing a configuration of a digital real security system according to a first embodiment of the present invention.

The present digital real security system includes a communication terminal 100 and a monitoring device 200, which is a main body of digital real security system equipment, communicating with the communication terminal 100 via a telephone line 210, the communication terminal 100 being capable of receiving respiration information from an abdominal pressure sensor 10 worn on a user (person) and used for sensing abdominal expansion and contraction in order to output an abdominal pressure signal and a respiration sensor 20 used for detecting human respiration in order to output a respiration signal.

Further, when the digital real security system provides a service of a security contract to the communication terminal 100, the user of the communication terminal 100 may be referred to as a user from the viewpoint of the digital system.

Also, this configuration may be such that the monitoring device 200 is incorporated into the communication terminal 100 depending on the intended use, but in the present embodiment, a description will be given of a configuration in which the communication terminal 100 is separated from the monitoring device 200.

The communication terminal 100 is composed of a mobile phone, a PHS (personal handyphone system) phone, a PDA (personal digital assistant), a smart phone, and the like, and transmits a sound transmission and a device operation cancellation command to the monitoring device 200 via a telephone line 210. In the present embodiment, a mobile phone or a smart phone is used as the communication terminal 100, and each individual can use it at various locations (i.e., current locations). One of the communication terminals 100 is located at a security company 220 together with a PC (personal computer). The communication terminal 100 is capable of receiving an e-mail message, an image including a moving image, and the like from the monitoring apparatus 200 via the telephone line 210.

[ Abdominal pressure sensor 10]

The abdominal pressure sensor 10 senses the abdominal expansion and contraction of the user to output an expansion/contraction signal (abdominal pressure signal). Abdominal pressure may be detected based on the inflation/deflation signal. Here, the expansion/contraction signal is considered to be superimposed with a respiration signal component which is a component of respiration. The abdominal pressure sensor 10 is fitted to, for example, a belt or the like of a user to detect pressure from the abdomen of the user. For the pressure sensor that detects pressure, a pressure-sensitive sensor may be used. The pressure sensitive sensor detects pressure applied to the sensing surface and continuously outputs a voltage value according to the detected value. The output value of the pressure-sensitive sensor is determined by the magnitude of the applied pressure and the magnitude of the area receiving the pressure. The abdominal pressure signal acquired by the abdominal pressure sensor 10 is output to the communication terminal 100, wherein the communication terminal 100 is the object of the present invention in a wireless communication manner.

Further, details of abdominal pressure detection in which abdominal expansion and contraction are sensed by the abdominal pressure sensor 10 to detect abdominal pressure will be described later with reference to fig. 2.

[ respiration sensor 20]

The respiration sensor 20 captures the motion of the body surface due to respiration. Although not the subject of the present invention, the respiration sensor 20 will be described for the understanding of the present invention. For example, with a microwave doppler sensor, the respiration sensor 20 senses respiration (whether the respiration rate is high or low, breathing or not) based on minute body motion by the microwaves (2.4GHz) transmitted from the sensor. Using an adhesive sensor with a built-in acoustic transducer as another example, the breath sensor 20 distinguishes between airflow (incoming and outgoing) in the respiratory tract to continuously detect the breath rate. The respiration signal acquired by the respiration sensor 20 is output to the communication terminal 100, wherein the communication terminal 100 is an object of the present invention in a wireless communication manner.

Here, the abdominal pressure sensor 10 transmits the expansion/contraction signal to the communication terminal 100 at all times. Also, the respiration sensor 20 transmits a respiration signal to the communication terminal 100 at all times.

Further, in the present embodiment, the abdominal pressure sensor 10 is fitted to the abdomen (e.g., a belt) of the user and the respiration sensor 20 is fitted to the body surface of the user. However, the abdominal pressure sensor 10 and the respiration sensor 20 may be of an integrated construction. The abdominal pressure respiration signal of the abdominal pressure sensor 10 and the respiration signal of the respiration sensor 20 are transmitted to the communication terminal 100. The abdominal pressure sensor 10 and the respiration sensor 20 are worn on employee(s) or the like who wish to send an emergency signal upon intrusion by a robber(s), such as employee(s) of a store, like a convenience store or a bank. Also, as in a second embodiment to be described later, the abdominal pressure sensor 10 and the respiration sensor 20 may be worn on the employee(s) of an armored car, bus, taxi, or the like.

[ communication terminal 100]

The communication terminal 100 is configured to include an abdominal pressure signal acquisition unit 101 that acquires an abdominal pressure signal from the abdominal pressure sensor 10 and a respiratory signal from the respiratory sensor 20, an abdominal pressure signal extraction unit 102 that subtracts a respiratory signal component from the acquired abdominal pressure signal to extract an abdominal pressure signal in which the influence of respiration is suppressed, a GPS (global positioning system) function unit 103, a communication unit 104, a storage unit 105, and a control unit 110 that controls the communication terminal as a whole.

The abdominal pressure signal acquisition unit 101 acquires the abdominal pressure signal detected by the abdominal pressure sensor 10 and the respiration signal detected by the respiration sensor 20 wirelessly or through wiring. Examples of the wireless communication system are Bluetooth (registered trademark), Wi-Fi (wireless fidelity) radio including ieee802.11b standard, specified low power radio, ultra wide band transmission system such as UWB (ultra wide band), and infrared communication. Also, a wired connection through an interface such as USB (universal serial bus) is available.

The abdominal pressure signal extraction unit 102 subtracts the respiratory signal component of the respiration sensor 20 superimposed on the expansion/contraction signal as noise from the acquired expansion/contraction signal using a signal processing circuit such as, for example, a DSP (digital signal processor) to extract the expansion/contraction signal in which the influence of respiration is suppressed.

The GPS function unit 103 receives radio waves of position information from GPS satellites or the like. The GPS functional unit 103 calculates current position information as two parameters of latitude and longitude from information received via the GPS antenna to acquire position information. Generally, the altitude information may also be acquired by the GPS, but is not used in the present embodiment.

Further, in the present embodiment, an example of using a GPS satellite has been mentioned as a means for acquiring position information, but it may be other means than GPS that uses a positional relationship with a base station. For example, when an Android (registered trademark) smart phone or a high-function mobile phone with a camera is used as the communication terminal 100 as a mobile terminal, it is also possible to acquire current location information of its own terminal by proximity check by performing transmission/reception of information with a mobile phone company server via a base station and a mobile phone communication network (not shown) used in place of or in combination with the GPS function unit 103.

Also, location information acquisition by Wi-Fi positioning, i.e., location information acquisition using a Wi-Fi access point and a predetermined location information service, may be used.

The communication unit 104 performs transmission/reception with a base station, similarly to a general communication terminal. In the present embodiment, the communication terminal 100 transmits the position information of the communication terminal 100 to the monitoring device 200 via the communication unit 104 every predetermined period, and transmits a notification about the occurrence of an abnormality and the latest position information about the occurrence of an abnormal situation.

The storage unit 105 is constituted by a nonvolatile memory such as an EEPROM (electrically erasable programmable read only memory), and retains information even after the power of the main body is turned off. The storage unit 105 stores ID information of its own terminal, registration setting information (refer to fig. 2) for acquiring abdominal pressure information from the abdominal pressure sensor 10, registration setting information (refer to fig. 2) for acquiring respiratory information from the respiratory sensor 20, and an abdominal pressure pattern program for determining the occurrence of an abnormality.

The control unit 110 is constituted by a CPU (central processing unit) or the like, and performs control of the communication terminal 100 as a whole, and performs control to determine occurrence of an abnormal situation and report the abnormal situation.

The control unit 110 includes a registration unit 111 that registers registration setting information to acquire breathing information, and an abnormality determination unit 112 that determines that an abnormal situation occurs based on the abdominal pressure signal from which the breathing signal component has been subtracted by the abnormality determination unit 112.

The abdominal pressure signal extracted by the abdominal pressure signal extraction unit 102 is repeatedly transmitted to the abnormality determination unit 112. When the abdominal pressure signal indicates an abnormal condition, it is determined that the abnormal condition has occurred. Generally, the abdomen expands and contracts according to normal breathing, but sometimes expands and contracts independently of breathing. Thus, simply determining that a change in the extracted abdominal pressure signal is simply an anomaly results in an erroneous report. Thus, the intentional expansion/contraction of the person is detected to determine the abnormality. This determination may be in situations such as the abdominal pressure signal having an unusual magnitude, the rate of change of the abdominal pressure signal having an unusual magnitude, or the change of the abdominal pressure signal having an unusual pattern (abdominal pressure pattern).

The registration unit 111 and the abnormality determination unit 112 are programs. In the following, when the subject is described as the "XX unit", the CPU reads out the abdominal pressure mode program from the storage unit 105 as necessary, then loads it into a main storage unit (not shown), and performs the corresponding function (described later). The abdominal pressure mode program may be stored in the storage unit 105 in advance, or may be carried to the communication terminal 100 via another storage medium or communication medium as needed.

[ monitoring apparatus 200]

The monitoring apparatus 200 includes a control unit 201, an input unit 202, and an alarm transmission unit 203. The monitoring device 200 may be a common server computer, personal computer, or the like.

The control unit 201 is constituted by a CPU or the like, and controls the devices as a whole and executes a security program to function as a digital real security system. The control unit 201 has a memory (not shown) that stores information. A semiconductor Memory such as an SD (secure digital) card, a USB (universal serial bus) Memory, or a Memory Stick (Memory Stick), a magnetic recording device, an optical disc device, a magneto-optical disc drive device, or the like may be the Memory.

The control unit 201 includes a location information acquisition unit 201a that tracks the existing location of the communication terminal 100 serving as an information recipient and acquires location information of the communication terminal 100, and a jurisdiction holding unit 201b that holds the police jurisdiction in which the mobile phone is located. Here, the jurisdiction of the police receiving the mobile phone call is based on one county (prefecture) in japan. When an emergency has been detected, the control unit 201 refers to the jurisdiction holding unit 201b to perform control to specify the communication terminal 100 serving as an information recipient that is present within the police jurisdiction of the communication terminal 100 serving as an information sender, and to report to the specified communication terminal 100 with priority.

The control unit 201 determines a sound transmission (warning an intruder) and a knock-down device operation command transmitted from the communication terminal 100 that has received the report, and if these commands are, may even output a sound signal to a speaker (not shown) via the input unit 202 and output an operation signal to a knock-down device (not shown).

The input unit 202 has a function as an abnormal situation detection means that detects an abnormal situation based on an abnormal determination result from the communication terminal 100 serving as an information sender. The input unit 202 receives position information of the corresponding communication terminal 100 transmitted from the communication terminal 100 via the telephone line 210, and outputs these signals to the control unit 201.

The alarm transmission unit 203 transmits an e-mail message or an image including a moving image to the other communication terminal 100 and the security company 220 via the telephone line 210.

When receiving e-mail messages, images, etc. from the present digital real security system, the security company 220 performs an investigation of the abnormal situation. Further, the security company 220 is not an indispensable structural element of the digital realistic security system according to the present embodiment.

[ registration setting information ]

Fig. 2 is a graph showing registration setting information of the abdominal pressure sensor 10, the respiration sensor 20, and the communication terminal 100.

As shown in fig. 2, the storage unit 105 of the communication terminal 100 stores registration setting information 120, which is referred to when the abdominal pressure mode program is executed. The breathing information of the communication terminal 100 is set as the registration setting information 120 associated with the abdominal pressure sensor 10 and the breathing sensor 20 for each user of the present system. Such registration setting information 120 is transmitted to the monitoring apparatus 200 in advance and registered in the monitoring apparatus 200, and also in the monitoring apparatus 200, abdominal pressure information of the communication terminal 100 of each user of the present system can be referred to.

As the registration setting information 120, the abdominal pressure sensor 10 and the respiration sensor 20 and the communication terminal 100 are associated with each other for each user. Specifically, the name, the mobile phone number, and the abdominal pressure information at normal time of the user are items on the abdominal pressure sensor 10 side, the name, the mobile phone number, and the breathing information at normal time of the user are items on the breathing sensor 20 side, and the name, the abdominal pressure sensor code, the breathing sensor number, the monitoring apparatus 200(DS2) information, the abdominal pressure information at normal time, and the breathing information at normal time of the user are used for the communication terminal 100. Also, in the storage unit 105, an abdominal pressure pattern program is registered. The abdominal pressure mode program is registered in the communication terminal 100 and the monitoring apparatus 200, respectively.

Hereinafter, the operation of the digital real security system configured as described above will be described.

[ registration processing ]

First, registration processing of the abdominal pressure sensor 10, the respiration sensor 20, the communication terminal 100, and the monitoring apparatus 200 will be described.

Fig. 3 is a flowchart showing a registration process of the abdominal pressure sensor 10, the respiration sensor 20, and the communication terminal 100. The present flow is mainly executed by the registration unit 111 (fig. 1) of the control unit 110 of the communication terminal 100.

In step S1, the user sets the user' S name, mobile phone number, and abdominal pressure information at normal times, and the mobile phone number of the communication terminal to which the detected abdominal pressure information in the abdominal pressure sensor 10 is transmitted.

In step S2, the user sets the name, mobile phone number, and abdominal pressure information at normal times of the user and the mobile phone number of the communication terminal 100 to which the detected breathing information in the breathing sensor 20 is transmitted.

In step S3, the registration unit 111 sets user information (name, sex, age, and the like), abdominal pressure sensor information, and respiratory sensor information by pairing operation with the abdominal pressure sensor 10 and the respiratory sensor 20 using a wireless communication means such as Bluetooth or specified low-power radio, and registers the information as registration setting information 120 in the storage unit 105 (refer to fig. 2). In addition to basic information such as name, gender and age, it is preferable to store user business types to which the present system is mainly applied as the above user information in order to enhance the effectiveness of the digital real security system in case of a security problem.

Next, registration processing of the abdominal pressure sensor 10, the respiration sensor 20, the communication terminal 100, and the monitoring apparatus 200 will be described.

Fig. 4 is a flowchart showing the registration process of the monitoring apparatus 200 (fig. 1). The present flow is mainly executed by the control unit 201 of the monitoring apparatus 200.

In step S11, the control unit 201 registers in advance the user information transmitted from the communication terminal 100 as monitoring device registration setting information (not shown). As the monitoring device registration setting information, user information of the abdominal pressure sensor 10 and the respiration sensor 20 related to the communication terminal 100, a mobile phone number, a name, a password, a contact address, normal respiration information, and the like of the communication terminal are registered.

In step S12, the control unit 201 registers an abdominal pressure pattern program indicating an abdominal pressure pattern.

[ terminal monitor control ]

Next, monitoring control of the communication terminal 100 of the digital real security system will be described.

Fig. 5 is a flowchart showing a monitoring control process of the communication terminal 100 of the digital real security system. The present flow is mainly executed by the control unit 110 (fig. 1) of the communication terminal 100.

First, in step S21, the GPS functional unit 103 acquires current position information of the communication terminal 100.

In step S22, the control unit 110 transmits the acquired location information of the communication terminal 100 to the monitoring apparatus 200 via the communication unit 104 every predetermined time (for example, one hour). The control unit 201 of the monitoring apparatus 200 receives the position information from the communication terminal 100 by the input unit 202. Thereby, the monitoring apparatus 200 can be notified of the latest position information of the communication terminal 100, for example, every hour. In the present embodiment, it is assumed that the user carries the abdominal pressure sensor 10, the respiration sensor 20, and the communication terminal 100 with him. Thus, the monitoring device 200 can be notified of the current location of the user using the abdominal pressure sensor 10 and the respiration sensor 20.

Further, if the system resource permits, the position closer to the current position may be notified by setting the above predetermined time to, for example, every 10 minutes. Alternatively, the pattern of the predetermined time described above may be changed according to the degree of urgency, necessity, or importance. Here, the location information of the user (communication terminal 100) is an example of a more preferred embodiment of the digital real security system, and is not indispensable. That is, it is sufficient that the user's abnormal change based on the abdominal pressure pattern of the user can be determined at the monitoring apparatus 200 side using the abdominal pressure sensor 10 and the respiration sensor 20. It is a unique effect that an abnormal change of a user can be notified without an attacker being aware of it or the like. However, if not only an abnormal change of the user but also the current position of the user (communication terminal 100) can be notified, a more appropriate response can be taken.

In step S23, the abdominal pressure signal acquisition unit 101 always acquires the abdominal pressure signal and the respiration signal of the abdominal pressure sensor 10 and the respiration sensor 20 of the user, respectively, and the control unit 110 monitors the acquired abdominal pressure signal and the respiration signal of the user.

In step S24, the control unit 110 starts the abdominal pressure mode routine, and determines abnormality of the abdominal pressure of the user based on the abdominal pressure information and the breathing information. Details of the abdominal pressure abnormality determination will be described later with reference to fig. 6.

In step S25, the abnormality determination unit 112 determines whether the abdominal pressure of the user is abnormal, and if the abdominal pressure of the user is abnormal, the process moves to step S26, whereas if the abdominal pressure of the user is not abnormal, the process returns to step S21 described above.

In step S26, the control unit 110 moves to the emergency mode to transmit an electronic mail message about the occurrence of an abnormality to the monitoring apparatus 200 via the communication unit 104 and to transmit the latest position information of the communication terminal 100. Further, if it takes a long time to acquire the latest position information of the communication terminal 100 in the emergency mode (such as a failure to acquire GPS position information), it is preferable to first have the abnormality occurrence notified without waiting for the latest position information acquisition. Also, the position information acquired last time may be transmitted.

This allows the abnormal situation to be reliably reported as intended by the user without being made aware of the robber.

In the present embodiment, the abdominal pressure sensor 10 always transmits the abdominal expansion/contraction signal to the communication terminal 100, and the respiration sensor 20 also always transmits the respiration signal to the communication terminal 100, and therefore, the communication terminal 100 can determine the abnormal state in real time based on the extracted abdominal pressure signal.

[ Exception determination processing ]

Fig. 6 is a flowchart showing abdominal pressure abnormality determination processing performed by the abnormality determination unit 112 of the communication terminal 100, and is a subroutine of step S24 of fig. 5.

First, in step S31, the abdominal pressure signal acquisition unit 101 acquires the abdominal pressure signal of the abdominal pressure sensor 10 of the user. This abdominal pressure signal is an expansion/contraction signal, for example, based on abdominal expansion and contraction.

In step S32, the abdominal pressure signal acquisition unit 101 acquires the breathing signal of the breathing sensor 20 of the user.

In step S33, the abdominal pressure signal extraction unit 102 regards the abdominal pressure signal as a signal and the respiratory signal as noise, and subtracts the respiratory signal from the acquired abdominal pressure signal. Specifically, the abdominal pressure signal extraction unit 102 subtracts the respiration signal component superimposed on the expansion/contraction signal from the expansion/contraction signal according to the abdominal expansion and contraction detected by the abdominal pressure sensor 10 to obtain the expansion/contraction signal with the influence of respiration suppressed.

The abdominal pressure sensor 10 detects an expansion/contraction signal according to abdominal expansion and contraction. However, the present inventors have found that the expansion/contraction signal contains, as noise, the influence of respiration that is present in a superimposed manner on the length of the intentional abdominal expansion/contraction as a person. Therefore, by subtracting the respiration signal detected by the respiration sensor 20 from the expansion/contraction signal detected by the abdominal pressure sensor 10, an intentional expansion/contraction signal of the person whose influence of respiration is suppressed is acquired.

Onward in step S34, an abnormality is determined using the inflation/deflation signal from which the respiration signal has been subtracted by the abdominal pressure signal extraction unit 102. That is, the respiration signal is acquired separately from the abdominal pressure signal, and the abnormality is determined based on the abdominal pressure signal from which the respiration signal has been subtracted, treating the respiration signal as noise.

The abnormality determination unit 112 determines in step S34 whether the abdominal pressure signal, which is the inflation/compression signal after subtracting the respiration signal, coincides with a signal of a predetermined pattern determined in advance for reporting an abnormality. If the expansion/compression signal after subtraction of the respiration signal matches the signal of the predetermined pattern (yes at S34), it is determined to be abnormal, and the process proceeds to step S35.

If the expansion/compression signal after subtraction of the respiration signal does not match the signal of the predetermined pattern (no in S34), it is determined to be normal, and the process proceeds to step S36.

In step S35, the abnormality determination unit 112 determines that an abnormal situation has occurred to the user, returning to step S24 of fig. 5.

In step S36, the abnormality determination unit 112 determines that an abnormal situation of security has not occurred to the user, returning to step S24 of fig. 5.

Since the abnormality determination unit 112 determines the abnormality of the security target person based on the expansion/contraction signal in which the influence of respiration is suppressed, the respiration signal component that changes according to respiration is subtracted, only the intentional abdominal expansion/contraction of the person is accurately detected, and thus erroneous reporting and failure reporting are prevented to improve reliability, while only the safety abnormality of the user covered by the present system is determined.

[ report control of the monitoring apparatus 200]

< reporting example 1>

Fig. 7 is a flowchart showing a report control operation of the monitoring device 200 of the digital real security system. The present flow is mainly executed by the control unit 201 (fig. 1) of the monitoring apparatus 200.

First, in step S41, the control unit 201 waits until the input unit 202 receives abnormality determination information from the communication terminal 100 through an email message. Alternatively, it may be determined whether the abnormality determination information and the latest position information of the communication terminal 100 have been received. In the present embodiment, the communication terminal 100 is constituted by a mobile phone, a smartphone, or the like that is capable of mobile communication and is used at each individual's location (i.e., presence location). The monitoring apparatus 200 receives the normal notification every predetermined time (for example, one hour) so as to store the position of the communication terminal 100 at the normal time when the abnormality determination is not notified from the communication terminal 100.

If abnormality determination information has been received from communication terminal 100, control unit 201 determines in step S42 which one of the counties that is the district in which emergency alert telephone call reception is located based on the received location information of communication terminal 100.

In step S43, the control unit 201 preferentially transmits an email message instructing reporting to the police 230 (refer to fig. 1) to the communication terminal 100 determined to be within a suitable county as the jurisdiction in which the security subject building is located.

In step S44, the control unit 201 of the monitoring device 200 transmits a result email message that has reported to the police 230 to the other communication terminal 100 and the security company 220 (refer to fig. 1) to end the present flow.

As described above, the present report example 1 is about priority reporting to information recipients who are in the same police administrative district as the user (victim).

In particular, the present report example 1 is only about reporting to other communication terminals 100, security companies 220, and police 230, and intentionally does not warn, threaten, or the like to the communication terminal 100 of the user (victim). That is, this is to protect the body of the user (victim) without irritating the robber, and also to consider the case where the user (victim) is in such a dangerous situation that he/she cannot even use his/her voice. The present system has a unique effect that an abnormal situation can be reliably reported intentionally by a user without being recognized by a robber, and the present reporting example 1 can achieve a maximized effect of reporting an abnormal situation without being recognized by a robber.

< reporting example 2>

Report example 2 is an example of an application to service operation buildings such as stores, banks, corporate offices, station/terminal buildings, currency exchanges, securicars, buses or taxis, and individual homes (hereinafter, stores, etc.).

The above-mentioned shop or the like mounts a plurality of monitoring cameras, and a predetermined monitoring area can be photographed. Also, the monitoring camera may follow a specific person or a photographing position. Even if the monitoring camera does not follow the shooting position, a person or the like can be shot from various angles by installing a plurality of monitoring cameras.

A digital real security system in a shop or the like will be described.

Fig. 8 is a flowchart showing a report control operation of the monitoring device 200 of the digital real security system in a shop or the like. The present flow is mainly executed by the control unit 201 (fig. 1) of the monitoring apparatus 200. Steps for performing the same processing as in fig. 7 are denoted by the same reference numerals.

First, in step S51, the control unit 201 waits until the input unit 202 receives abnormality determination information from the communication terminal 100 through an email message.

If abnormality determination information has been received from the communication terminal 100, the control unit 201 notifies the relevant shop office, headquarters, security company, etc. of the abnormality by an email message based on the received location information of the communication terminal 100 and requests the relevant user to be photographed by the monitoring camera in step S52. Based on the user photographing request of the monitoring apparatus 200, a shop office, a headquarters, a security company, and the like photograph a moving image of the user at the relevant shop or the like through the monitoring camera and transmit the moving image to the monitoring apparatus 200.

In step S53, the acquired real-time moving image of the user is visually confirmed.

In step S54, input of a visual confirmation result by the input unit 202 is awaited.

As a result of the visual confirmation, if the abnormality is confirmed, the control unit 201 preferentially transmits an email message instructing to report to the police 230 to the communication terminal 100 determined to be in a suitable county as the jurisdiction in which the security subject building is located in step S43.

In step S44, the control unit 201 of the monitoring device 200 transmits a result email message that has reported to the police 230 to the interested party, the other communication terminal 100, and the security company 220 to end the present flow.

The present report example 2 is about protecting the body of a user (victim) without irritating the robber, and also considering the case where the user (victim) is in such a dangerous situation that he/she cannot even use his/her voice. The system can be used for intentionally and reliably reporting the abnormal condition by a user without being realized by a robber. In particular, since the present report example 2 is a real-time moving image about an environment in which the user is visually confirmed when determining an abnormality, more reliable abnormality determination can be performed, and more appropriate measures can be implemented.

< reporting example 3>

By reporting instances 1 and 2, abnormal situations can be reported without being realized by the robber.

Reporting example 3 is an example of reporting an abnormal situation without being realized by a robber and then threatening the robber.

Fig. 9 is a flowchart showing a report control operation of the monitoring apparatus 200 of the digital real security system in a shop or the like. The present flow is mainly executed by the control unit 201 (fig. 1) of the monitoring apparatus 200. Steps for performing the same processing as in fig. 8 are denoted by the same reference numerals.

First, in step S61, the control unit 201 waits until the input unit 202 receives abnormality determination information from the communication terminal 100 through an email message.

If abnormality determination information has been received from the communication terminal 100, the control unit 201 notifies the relevant shop office, headquarters, security company, etc. of the abnormality by an email message based on the received position information of the communication terminal 100 and causes the communication terminal 100 of the user to produce a sound by automated voice to confirm the situation in step S62.

In step S63, the control unit 201 requests photographing of the user by the monitoring camera. Based on the user photographing request of the monitoring apparatus 200, a shop office, a headquarters, a security company, or the like acquires a moving image of the user in the shop or the like through the monitoring camera and transmits the moving image to the monitoring apparatus 200.

In step S64, the control unit 201 determines whether there is a response from the communication terminal 100 of the user in response to the situation confirmation of the automated voice. If there is no response from the communication terminal 100 of the user, the control unit 201 re-notifies the relevant store or the like of the emergency (abnormal situation) by attaching the photograph to the email message in step S65.

If there is a response from the user' S communication terminal 100, the retrieved real-time moving image of the user is visually confirmed to determine whether it is abnormal, problematic, or not in step S66.

As a result of the visual confirmation, when it is abnormal, the control unit 201 requests the headquarters of the shop or the like to make a sound report to an appropriate location in the shop (the location in the shop where the user is located) in step S67. The headquarters of the store or the like receives this request to place a threat (such as a threat tone or warning message) by an audible notification toward the appropriate location within the store.

In step S68, after confirmation of an emergency by the headquarters of the shop or the like and/or the security company, the control unit 201 preferentially transmits an email message instructing reporting to the police 230 to the communication terminal 100 determined to be in a suitable county as the jurisdiction in which the security subject building is located, based on the position of the user.

In step S44, the control unit 201 of the monitoring device 200 transmits a result email message that a report has been made to the police 230 to the interested party, the other communication terminal 100, and the security company 220 to end the present flow.

As a result of the visual confirmation, if there is a problem, the control unit 201 requests the head office of the shop or the like to make a user take a predetermined action (such as an action to notify not an emergency) by sound in step S69. The headquarters of the store or the like, by receiving this request, instructs the user to take appropriate action through a voice message.

In step S70, based on a response from the headquarters of the shop or the like, the control unit 201 determines whether the user has performed an action as instructed. If the user has performed the action as instructed, it is determined not to be abnormal, and proceeds to step S71, whereas if the user has not performed the action as instructed, it is determined to be abnormal, and proceeds to step S68.

If it is determined in the above-described step S66 that it is not abnormal or if the user has performed an action as instructed, the control unit 201 notifies the user and the other communication terminal 100 in step S71 that the emergency mode has been cancelled to end the present flow.

As described above, in the present reporting example 3, the head office of the shop that has received the abnormal situation confirms the moving image of the monitoring camera and threatens the robber, and can thereby prevent the accident. Also, the monitoring apparatus 200 detects an abnormal situation, checks a moving image of the monitoring camera, and threatens an intruder through the speaker. In such cases where a third party is not involved in the trouble, a roll-off device (not shown) may be activated to roll off the intruder.

< reporting example 4>

Similar to reporting example 3, reporting example 4 is an example of reporting an abnormal situation without being realized by the robber and then threatening the robber.

Fig. 10 is a flowchart showing a report control operation of the monitoring device 200 of the digital real security system at a company or an individual. The present flow is mainly executed by the control unit 201 (fig. 1) of the monitoring apparatus 200. Steps for performing the same processing as in fig. 9 are denoted by the same reference numerals.

First, in step S61, the control unit 201 waits until the input unit 202 receives abnormality determination information from the communication terminal 100 through an email message.

If abnormality determination information has been received from the communication terminal 100, the control unit 201 notifies the relevant family, security company, company headquarters, etc. of the abnormality by an e-mail message based on the received position information of the communication terminal 100 and causes the communication terminal 100 of the user to produce a sound by automated voice to confirm the situation in step S81.

In step S82, the control unit 201 issues the above-described email message to family or corporate headquarters, and then determines whether there is a response to the email message within a predetermined time (e.g., three minutes).

If there is no response even within a predetermined time (for example, three minutes) after the above-described email message is issued, the control unit 201 notifies other users (other communication terminals 100) that an abnormality may have occurred to the user through the email message in step S83.

In step S64, the control unit 201 determines whether there is a response from the communication terminal 100 of the user in response to the situation confirmation of the automated voice. If there is no response from the user' S communication terminal 100, the control unit 201 re-notifies the relevant store or the like of the emergency by attaching the photograph to the e-mail message in step S65.

In step S84, the control unit 201 requests photographing of the periphery of the building by the monitoring camera. Based on the user photographing request of the monitoring apparatus 200, a shop office, a headquarters, a security company, and the like photograph a moving image of the periphery of a building through a monitoring camera and transmit the moving image to the monitoring apparatus 200.

In step S66, the acquired real-time moving image of the user is visually confirmed to determine whether it is abnormal, problematic, or not.

As a result of the visual confirmation, if it is abnormal, the control unit 201 requests the headquarters of the shop or the like to make a sound report to an appropriate location in the shop (the location in the shop where the user is located) in step S67. The headquarters of the store or the like receives this request to audibly notify a threat (such as a threat tone or warning message) toward the appropriate location within the store.

In step S68, after confirmation of an emergency by the headquarters of the shop or the like and/or the security company, the control unit 201 preferentially transmits an email message instructing reporting to the police 230 to the communication terminal 100 determined to be in a suitable county as the jurisdiction in which the security subject building is located, based on the position of the user.

In step S44, the control unit 201 of the monitoring device 200 transmits a result email message that a report has been made to the police 230 to the interested party, the other communication terminal 100, and the security company 220 to end the present flow.

As a result of the visual confirmation, if there is a problem, the control unit 201 requests the head office of the shop or the like to make a user take a predetermined action (such as an action to notify not an emergency) by sound in step S69. The headquarters of the store or the like receives this request and instructs the user to take appropriate action via a voice message.

In step S70, based on a response from the headquarters of the shop or the like, the control unit 201 determines whether the user has performed an action as instructed. If the user has performed the action as instructed, it is determined not to be abnormal, and proceeds to step S71, and if the user has not performed the action as instructed, it is determined to be abnormal, and proceeds to step S68.

If it is determined in the above-described step S66 that it is not abnormal or if the user has performed an action as instructed, the control unit 201 notifies the user and the other communication terminal 100 in step S71 that the emergency mode has been cancelled to end the present flow.

As described above, even in the event that the employee is threatened by a threat and cannot take any action, the monitoring device 200 can report an abnormal situation to the office and headquarters of the store and the security company 220 in order to dial the emergency number 110 to the police 230 (i.e., make an emergency call) in real time without the threat being aware of it.

As specifically described above, according to the present embodiment, the digital realistic security system includes the abdominal pressure signal acquisition unit 101 that acquires an abdominal pressure signal from the abdominal pressure sensor 10 for detecting the abdominal pressure of the user and acquires a respiratory signal from the respiratory sensor 20 for detecting the respiration of the user, the abdominal pressure signal extraction unit 102 that subtracts a respiratory signal component from the acquired abdominal pressure signal to extract an abdominal pressure signal whose influence of the respiration is suppressed, the abnormality determination unit 112 that determines an abnormality of the user based on the abdominal pressure signal from which the respiratory signal component has been subtracted, and the alarm transmission unit 203 that reports an abnormal situation based on the determination result as the occurrence of the abnormal situation.

The abdominal pressure signal extracted by the abdominal pressure signal extraction unit 102 is repeatedly transmitted to the abnormality determination unit 112. When the abdominal pressure signal indicates an abnormal condition, it is determined that the abnormal condition has occurred.

That is, abdominal pressure is detected, breathing is detected separately therefrom, and abnormality is determined based on the result of the abdominal pressure signal from which the breathing signal has been subtracted, breathing being regarded as noise.

According to this configuration, the respiratory signal component that changes according to breathing is subtracted and only the intentional abdominal pressure of a person is accurately detected, so this prevents false reports and failure reports to improve reliability while allowing the victim to reliably report the occurrence of an emergency. Moreover, this configuration allows an abnormal situation to be reliably reported as intended by the user without being recognized by the robber.

For example, even in a case where he/she is threatened by a threat person (a robber) and cannot take any action, the user can be unaware of the robber by reporting an abnormal situation to his/her family (other communication terminal 100), the office and headquarters of the shop, and the security company 220 from a normal time change such as a change in his/her abdominal pressure pattern. Family members or the like may confirm and dial the emergency number 110 to the police 230 to prevent trouble or accidents.

Also, for an employee of a securicar, bus, taxi, precious metal, jewelry counter, etc., the employee's security may be ensured to protect him/her in case of a robbery. Moreover, even for the elderly, children, and those who are socially vulnerable because of health problems and even come from remote places, a supporting action of assistance can be provided in real time when an abnormal situation occurs. Therefore, the lives and property of the company or the individual employee can be protected in real time, as well as for the home, and the digital real security system is useful as a system for crime fighting measures, and its economic advantages and contribution are considerable.

For example, in the case where a robber invades a service operated building such as a shop, a bank, a company office, a station/terminal building, a currency exchange, a cash carrier, a bus, or a taxi and an individual's home, his/her employee can reliably report an abnormal situation by inflating and deflating his/her abdomen to become consistent with a predetermined abdominal pressure pattern, and his/her related family can dial the emergency number 110 to the police.

Also, when the abdominal pressure sensor 10 is stopped due to violence of a threat (robber) or the communication terminal 100 is robbed by the robber and signal communication between the abdominal pressure sensor 10 and the communication terminal 100 is not available, the communication terminal 100 transmits the current location identified by the GPS and the user is in an emergency to the monitoring apparatus 200, and the monitoring apparatus 200 further reports the situation to a person related to his/her company or family in real time, which allows the person related to the company or family to dial the emergency number 110 to the police. As described above, even when it is time for an employee to be threatened by a threatener and unable to take any action, the monitoring apparatus 200 can report an abnormal situation to the head office of the shop and the security company 220 to allow the emergency number 110 to be dialed to the police 230 in real time without being recognized by the threatener.

In the present embodiment, since the report is preferentially reported to the information recipients who are in the same police administrative district as the victim, the person who receives the report can promptly make an emergency call to the police of the police administrative district in which the victim is located.

Here, in order to increase the accuracy of the abnormality sensed by the abdominal pressure sensor 10, the same determination method may be repeated or different determination methods may be combined so as to finally determine that it is an abnormality when determined to be abnormal in all those cases.

(second embodiment)

The second embodiment of the invention is an example of an application to a user, a securicar, a bus, a taxi, etc.

The digital realistic security system according to the second embodiment of the present invention has the same hardware configuration as that of fig. 1, and thus a description thereof will be omitted.

Next, a registration process of the monitoring device 200 of the digital real security system will be described.

Fig. 11 is a flowchart showing a registration operation of the monitoring apparatus 200 (fig. 1). The present flow is mainly executed by the control unit 201 of the monitoring apparatus 200.

In step S91, the control unit 201 registers behavior information of the user of the securicar, bus, taxi, or the like as monitoring device registration setting information (not shown) in advance. As the monitoring apparatus registration setting information, user information of the abdominal pressure sensor 10 associated with the communication terminal 100, a mobile phone number of the communication terminal, a name, a password, a contact address, normal-time abdominal pressure information, and the like are registered. Also, an abdominal pressure pattern program is registered.

Fig. 12 is a flowchart showing a behavior monitoring control operation of the monitoring device 200 of the digital real security system. The present flow is mainly executed by the control unit 201 (fig. 1) of the monitoring apparatus 200.

First, if the user is a user of a securicar, a bus, a taxi, or the like, the control unit 201 sets the mode of the communication terminal 100 to a behavior monitoring mode in step S101. Also, the mode setting of the communication terminal 100 is similarly set to the behavior monitoring mode. In this case, there may be a mode in which the communication terminal 100 is first set to the behavior monitoring mode and reports its behavior monitoring mode to the monitoring device 200, and then the monitoring device 200 sets the behavior monitoring mode.

In step S102, the control unit 201 acquires the position information of the communication terminal 100 transmitted from the communication terminal 100 every 30 minutes, for example. Here, it is preferable that the notification of the positional information by the GPS in the present embodiment is every predetermined time (for example, 30 minutes) shorter than the predetermined time (for example, one hour) of the first embodiment. That is, the user (communication terminal 100) of the securicar, bus, taxi, or the like is likely to move within the car, and it is considered that the positional information is greatly changed in this case. Therefore, it is preferable to acquire the position information at each period shorter than the predetermined time of the first embodiment.

Also, even when the communication terminal 100 is in a place where radio communication is not available (such as in a tunnel), the position information can be continuously acquired by an autonomous navigation system using a gyroscope or the like. In addition, when the communication terminal 100 is thus in a place where radio communication is not available, the monitoring apparatus 200 cannot receive the position of the communication terminal 100 any more, but when it is assumed that the communication terminal 100 is in an area on a map where radio communication is not available, by determining that even a failure to acquire position information is not abnormal, an erroneous report can be prevented.

In step S103, the control unit 201 constantly monitors (here, every 30 minutes) the setting behavior program and the location information of the user of the securicar, bus, taxi, or the like.

In step S104, the control unit 201 determines whether a predetermined time (e.g., 30 minutes or more) has elapsed in terms of a mismatch between the setting behavior program and the position information of the GPS of the user of the securicar, bus, taxi, or the like.

If the predetermined time has not elapsed with respect to the mismatch between the setting behavior program and the position information of the GPS, it is determined that the setting behavior program and the position information are behaviorally matched to return to the above-described step S102. If a predetermined time has elapsed with respect to the mismatch between the setting behavior program and the position information of the GPS, it is determined that there is a behavioral mismatch between the setting behavior program and the position information of the GPS, and it proceeds to step S105.

In step S105, the control unit 201 determines whether a notification of occurrence of an abnormal situation from the user (the communication terminal 100) of the securicar, the bus, the taxi, or the like is received. Further, the determination of the abnormal situation has been described with reference to fig. 5.

If the notification of the occurrence of the abnormal situation has been received, the control unit 201 transmits an alarm to the communication terminal 100 of the user through an email message or sound via the alarm transmission unit 203 (fig. 1) and transmits the email message to the family, the company headquarters, or the like of the user in step S106. If the notification of the occurrence of the abnormal situation is not received, the control unit 201 returns to the above-described step S102.

In step S107, the control unit 201 determines whether there is a response from the communication terminal 100 of the user.

If there is a response from the communication terminal 100 of the user, the control unit 201 returns to the above-described step S102. In contrast, if there is no response from the user 'S communication terminal 100, the control unit 201 continues to monitor the location information by the GPS of the user' S communication terminal 100 in step S108.

In step S109, the control unit 201 determines whether a predetermined time (for example, 30 minutes or more) has elapsed with respect to a mismatch in behavior between the setting behavior program and the position information.

If the predetermined time has not elapsed with respect to the mismatch between the setting behavior program and the position information of the GPS, it is determined that the setting behavior program and the position information are behaviorally matched to return to the above-described step S102. If a predetermined time has elapsed with respect to the mismatch between the setting behavior program and the position information of the GPS, it is determined that there is a behavioral mismatch between the setting behavior program and the position information of the GPS, and it proceeds to step S110.

In step S110, the control unit 201 confirms an emergency, confirms the location of the user, and dials the emergency number 110 to the police through the head office and/or security company to end the present flow.

Here, as an example of the reporting method, as in the first embodiment, it is possible to preferentially report to information recipients who are in the same police administrative district as the victim.

As described above, according to the present embodiment, even when a threat person (robber) attacks an armored car, a bus, a taxi, or the like and threatens its employee, and the employee is restricted from taking any action or calling for help, the employee can reliably report the occurrence of an abnormal situation together with the current position information. Also, even when the headquarters contacts the employee through a phone whether there is any abnormality and hears his/her safety from the employee, if the behavior of the armored car, bus, taxi, etc. confirmed by the GPS is not along the prescribed route, the headquarters can dial the emergency number 110 to the police so that the accident can be prevented. In addition, moving images or photographs of a monitoring camera installed in a vehicle such as an armored car, a bus, a taxi, etc. are transmitted to a relevant person located at a company headquarters through e-mails to communicate an abnormal state of the armored car, the bus, the taxi, etc. The person located at the company headquarters that is concerned who received the e-mail confirms the situation in the car and, if it is an emergency situation, dials the emergency number 110 to the police and can thus respond to it by tracking the cash carrier, bus, taxi, etc. via GPS and a mobile terminal.

(third embodiment)

The third embodiment of the present invention is an example of reporting an abnormal situation different due to different abdominal pressure patterns in a differentiated manner.

The digital realistic security system according to the present embodiment has the same hardware configuration as that of fig. 1, and thus a description thereof will be omitted. In the present embodiment, the storage unit 105 of fig. 1 stores the abdominal pressure pattern shown in fig. 13.

Fig. 13 is a graph showing an example of an abdominal pressure pattern of the digital realistic security system according to the present embodiment.

As shown in fig. 13, each user has normal abdominal pressure and an abnormal state [ i.note, ii.abnormal condition, iii.emergency state ] as the abdominal pressure mode of the present embodiment.

For example, according to the personal level, the user a sets the I mode in which approximately two expansions and contractions are performed within ten seconds, serving as "i.note", the II mode is five times, serving as "ii.abnormal situation", and the III mode is ten times, serving as "iii.emergency state". The abdominal pressure pattern is created by repeating the above "i", "ii", or "iii" once or two to three times at intervals set depending on the situation in the field. Also, it is preferable to create the abdominal pressure pattern program by the industry of the user and/or by the classification of children, minors, adults and elderly persons.

As described above, according to the present embodiment, storing a plurality of different abdominal pressure patterns in advance allows the respective abnormal situations to be reported to be determined in a differentiated manner in response to the occurrence of various abnormal situations.

(fourth embodiment)

In the first to third embodiments, by subtracting the respiration signal detected by the respiration sensor 20 from the inflation/deflation signal detected by the abdominal pressure sensor 10, the intentional inflation/deflation signal of the person is acquired with the influence of respiration having been suppressed. However, the first to third embodiments are absolutely premised on the user wearing (using) the abdominal pressure sensor 10 and the respiration sensor 20, and are based on acquiring an intentional abdominal distension/contraction signal of the person. That is, the abdominal pressure sensor 10 and the respiration sensor 20 are used together in order to increase the reliability of the expansion/contraction signal.

However, if a rioter hijacks the user of the sensor and also wears the sensor, what will happen? In this case, since the present sensor itself is put on a rioter and then operated, an abnormality due to the stop of the operation of the present sensor cannot be determined. Also, the use of both the abdominal pressure sensor 10 and the respiration sensor 20 may increase the reliability of the inflation/deflation signal, but does not allow distinguishing whether the signal is from a user or a riot. Thus, the report will be made by breathing using the breathing sensor 20, but this is initially a way of reporting for the user without being apprehended by a rioter. Thus, if the present sensor is hijacked by a riot, it cannot be used. Also, if a rioter leaves the present sensor intact, there is a possibility that the occurrence of an abnormality can be sensed by judging a situation such as lack of response to a periodic transmission or a call. However, as described above, if a rioter hijacks the user of the present sensor and then wears the present sensor, it is difficult to determine an abnormality.

The fourth embodiment of the present invention is an example in which an abnormal situation can be reported even when a rioter robbes the user of the present sensor and wears the present sensor.

The digital realistic security system according to the present embodiment has the same hardware configuration as that of fig. 1, and thus description thereof will be omitted. In the present embodiment, the storage unit 105 of fig. 1 stores the abdominal pressure pattern at normal times and the number of breaths per unit time of the security target person in association with the corresponding security target person. Also, the abnormality determination unit 112 of fig. 1 verifies the normal-time respiration number/abdominal pressure pattern of the security target person stored in the storage unit 105 by matching to the normal-time respiration number/abdominal pressure pattern of the wearer of the present sensor acquired at this time, thereby determining an abnormality.

Fig. 14 is a schematic diagram showing the configuration of the chest/abdomen movement signal detecting apparatus 300. Fig. 15 is an enlarged view of a main portion of the moving position sensor of fig. 14. The chest/abdomen movement signal detecting apparatus 300 of fig. 14 shows a specific example of the abdomen pressure sensor 10 of fig. 1. Also, as communication means between the chest/abdomen movement signal detecting apparatus 300 of fig. 14 and the communication terminal of fig. 1, the case of bluetooth (registered trademark) is used as an example. Further, the communication means may be other wireless communication means, such as a Wi-Fi radio or a designated low power radio or a wired connection through an interface such as USB.

As shown in fig. 14, the chest/abdomen movement signal detecting apparatus 300 includes a fixed portion 310 serving as a reference of movement in a main body 300a, and a substantially rectangular-shaped moving part 320 that moves relative to the fixed part 310 due to abdominal pressure, two springs 321 that bias the moving part 320 toward the fixed part 310, an elongated sensor unit 330 provided on the fixed part 310 and disposed to extend along a side surface of the moving part 320 and sense a moving position of the moving part 320 in a tension direction of abdominal pressure and a direction opposite thereto, a signal detection circuit 340 processing a signal sensed by the sensor unit 330 to detect an abdominal pressure signal, a bluetooth transmitter 350 transmitting the detected abdominal pressure signal to the communication terminal 100 (refer to fig. 1), and a power supply unit 360 composed of a button battery or the like, which supplies power to the respective units. Further, the moving portion 320 is moved within an appropriate range due to a guide (not shown).

The fixed part 310 and the moving part 320 are fitted to, for example, a belt wrapped around the abdomen such that the distance therebetween is changed due to the change of abdominal pressure.

The sensor unit 330 is composed of an elongated moving position sensor 331 given on the fixed portion 310 and disposed to extend along a side surface of the moving portion 320, and a movable member 332 given on the moving portion 320 and protruding from the moving portion 320 toward the moving position sensor 331 and sliding without contact with an upper surface of the moving position sensor 331. The movable member 332 is fixed to the moving part 320, and slides over the upper surface of the moving position sensor 331 in conjunction with the movement of the moving part 320.

As shown in fig. 15, the moving position sensor 331 is composed of a plurality of detection sensors 331a of an elongated shape disposed in an established manner, and signal lines 331b from the respective detection sensors 331a are connected to a signal detection circuit 340. In the present embodiment, a photoelectric sensor is used as the detection sensor 331 a. As a result of the movable member 332 combined with the moving part 320 blocking any of the detection sensors 331a from receiving light, the detection sensor 331a detects a change in the amount of light received. Since the displacement of the respective detection sensors 331a corresponds to the movement position of the abdominal pressure, the movement position information of the abdominal pressure can be acquired based on the change in the amount of light received by the detection sensor concerned.

As shown by reference numerals a, b, and c of fig. 15, the movable member 332 may move the corresponding detection sensor 331a leftward and rightward along with the movement of the moving part 320. Reference numerals a and b of fig. 15 show an example in which the movable member 332 is in the normal breathing range, and reference numeral c of fig. 15 shows an example in which the movable member 332 is in the abnormal abdominal pressure range.

Further, providing a light emitting element (such as an LED) provided on the movable member side and a light receiving element provided on the detection sensor side allows further increase in detection accuracy. Also, as another example of the non-contact sensor, it is also possible to use a magnetic material for the side surface of the movable member 332 and a hall element for the corresponding detection sensor 331a, thereby detecting the position of the movable member 332 based on the change in the magnetic field. In addition, as a simple configuration, the sensor unit 330 may be a contact sensor. The touch sensor may be implemented using, for example, a conductive movable member connected to the signal detection circuit 340 and a conductive pad as a corresponding detection sensor. In this case, the conductive movable member slides in contact with the upper surface of the conductive pad, and the motion position information of the abdominal pressure can be acquired depending on the contact position with the corresponding detection sensor (conductive pad).

In the above-described configuration, as the chest/abdomen movement signal detection apparatus 300, a description is given of an example of being fitted to a belt and attached to the chest and abdomen of the user so as to acquire numerical movement values of the chest and abdomen, but the chest/abdomen movement signal detection apparatus 300 may be attached only to the abdomen. In this state, the moving portion 320 is biased toward the fixed portion in the direction of the rightward arrow of fig. 14 by the contracting force of the spring 321. Then, the moving part 320 is moved in the direction of the right arrow of fig. 14 by the tension due to the abdominal pressure of the user. The sensor unit 330 detects left and right moving states of the moving part 320 as a change in the received light amount by which the movable member 332 blocks the light received by the corresponding detection sensor 331 a. Based on a change in the amount of light received by the detection sensor, the signal detection circuit 340 detects movement position information (abdominal pressure signal) of the detection sensor of interest. The bluetooth transmitter 350 transmits the detected abdominal pressure signal to the communication terminal 100 (fig. 1).

Fig. 16 is graphs each showing an example of chest/abdomen movement value settings at the time of normal breathing of the user.

As the abdominal pressure pattern at the normal time of the user, the length around the chest and around the abdomen when the user inhales (a: inhale) and exhales (b: exhale) may be set to a numerical motion value in relation to the corresponding user. Together with this, the number of breaths per unit time can also be set in relation to the respective user. Specifically, for example, a numerical motion value of a predetermined number of breaths (for example, 20) or a numerical motion value of a predetermined time (for example, one minute) in normal breathing is detected. Fig. 16 (a) shows the numerical motion values of the chest and abdomen and the number of breaths in one minute of normal breathing. Similarly, a numerical motion value of a predetermined number of breaths (e.g., 20) or a numerical motion value of a predetermined time (e.g., one minute) at the time of normal breathing is detected as an updated setting after 30 minutes for the same user. Fig. 16 (b) shows the numerical motion values of the chest and abdomen and the number of breaths in one minute of normal breathing as the update setting after 30 minutes. As can be understood from comparison of (a) in fig. 16 with (b) in fig. 16, there is a variation depending on time even for the same user. Therefore, in the present embodiment, a predetermined margin is provided in advance as a tolerance using the variation.

Hereinafter, an operation of the digital real security system using the chest/abdomen movement signal detecting apparatus 300 configured as above will be described.

With the digital real security system of the present embodiment, similar to the registration processing (fig. 3) of the first embodiment, the following registration has been performed in advance by the registration unit 111 (fig. 1) of the control unit 110 of the communication terminal 100.

The control unit 201 (fig. 1) registers in advance the user information transmitted from the communication terminal 100 as monitoring device registration setting information (not shown). Here, the monitoring apparatus registration setting information is user information of the chest/abdomen motion signal detecting apparatus 300 and the respiration sensor 20 related to the communication terminal 100, a mobile phone number of the communication terminal, a name, a password, a contact address, respiration information at normal times, and the like.

Also, the control unit 201 of the monitoring apparatus 200 registers an abdominal pressure pattern program representing an abdominal pressure pattern. The abdominal pressure mode program is set based on the chest/abdominal motion values of fig. 16 during normal breathing. In particular, the storage unit 105 (fig. 1) has stored the normal number of breaths/abdominal pressure pattern of the security target person.

[ Exception determination processing ]

Fig. 17 is a flowchart showing abdominal pressure abnormality determination processing performed by the abnormality determination unit 112 of the communication terminal 100, and is a subroutine of step S24 of fig. 5. The contents of this flow are different from those of fig. 6, but the flow shown in the drawing is the same.

First, in step S131, the abdominal pressure signal acquisition unit 101 acquires the abdominal pressure signal of the chest/abdominal movement signal detection apparatus 300 of the user. This abdominal pressure signal is an expansion/contraction signal, for example, based on abdominal expansion and contraction.

In step S132, the abdominal pressure signal acquisition unit 101 acquires the breathing signal of the breathing sensor 20 of the user.

In step S133, the abdominal pressure signal extraction unit 102 regards the abdominal pressure signal as a signal and regards the respiratory signal as noise, and subtracts the respiratory signal from the acquired abdominal pressure signal. Specifically, the abdominal pressure signal extraction unit 102 subtracts the respiration signal component superimposed on the expansion/contraction signal from the expansion/contraction signal according to the abdominal expansion and contraction detected by the abdominal pressure sensor 10 to obtain the expansion/contraction signal with the influence of respiration suppressed.

The chest/abdomen motion signal detecting apparatus 300 detects an expansion/contraction signal according to the abdominal expansion and contraction. Here, by subtracting the respiration signal detected by the respiration sensor 20 from the expansion/contraction signal detected by the chest/abdomen motion signal detecting apparatus 300, the intentional expansion/contraction signal of the person is acquired with the influence of respiration having been suppressed.

Onward in step S134, an abnormality is determined using the inflation/deflation signal from which the respiration signal has been subtracted by the abdominal pressure signal extraction unit 102. That is, the respiratory signal is acquired separately from the abdominal pressure signal, and the anomaly is determined based on the result of the abdominal pressure signal from which the respiratory signal has been subtracted, the respiratory signal being considered noise.

The abnormality determination unit 112 determines in step S134 whether the abdominal pressure signal, which is the expansion/contraction signal after subtracting the respiration signal, coincides with the abdominal pressure signal of the predetermined pattern determined in advance for reporting the abnormality.

In addition, the abnormality determination unit 112 verifies the normal respiration count/abdominal pressure pattern of the security target person stored in the storage unit 105 (fig. 1) by matching to the normal respiration count/abdominal pressure pattern of the wearer of the present sensor at this time.

If the expansion/contraction signal after the subtraction of the breathing signal coincides with the expansion/contraction signal of the predetermined pattern and further if the matching verification result of the normal respiration number/abdominal pressure pattern of the security target person is a mismatch (yes in S134), it is determined to be abnormal, so that it proceeds to step S135.

If the expansion/contraction signal after the subtraction of the breathing signal does not coincide with the expansion/contraction signal of the predetermined pattern and the matching verification result of the normal respiration count/abdominal pressure pattern of the security target person is a match (no in S134), it is determined to be normal, and it proceeds to step S136.

In step S135, the abnormality determination unit 112 determines that an abnormal situation has occurred to the user, and then returns to step S24 of fig. 5.

In step S136, the abnormality determination unit 112 determines that an abnormal safety situation has not occurred to the user, and then returns to step S24 of fig. 5.

Since the abnormality determination unit 112 determines abnormality of the security target person based on the expansion/contraction signal in which the influence of respiration is suppressed, the respiration signal that changes according to respiration is subtracted, only intentional expansion/contraction of the person is accurately detected, and thus erroneous reporting and failure reporting are prevented to improve reliability, while only safety abnormality situations of the user covered by the present system are determined.

As described above, in the present embodiment, the chest/abdomen movement signal detecting apparatus 300 that detects the number of breaths and the abdomen pressure pattern of the person to whom the chest/abdomen movement signal detecting apparatus 300 is fitted and the storage unit 105 that stores the number of breaths and the abdomen pressure pattern of the user detected by the chest/abdomen movement signal detecting apparatus 300 are provided, and the abnormality determining unit 112 matches the number of breaths and the abdomen pressure pattern detected by the chest/abdomen movement signal detecting apparatus 300 with the number of breaths and the abdomen pressure pattern of the user stored in the storage unit 105 and determines whether or not it is abnormal based on the matching result, thus enabling matching verification even when the user of the chest/abdomen movement signal detecting apparatus 300 is hijacked and wears the apparatus by a hiker, to allow determination of an abnormal situation and thus reporting of the abnormal situation.

The above description is illustrative of the preferred embodiments of the invention and the scope of the invention is not limited thereto. The belt equipped with the chest/abdomen movement signal detecting apparatus 300 may be wound around both the chest and the abdomen or may be wound around only one of the chest and the abdomen. When the belt is wound around the chest, the pattern referred to as abdominal pressure pattern is of course actually a chest pattern. Also, the matching may be performed by matching both the number of breaths and the abdominal pressure pattern, or may be performed by matching only one of the number of breaths and the abdominal pressure pattern. For abdominal pressure pattern matching, common pattern matching techniques may be used. Thus, for example, the matching may be by comparison of the length around the abdomen. Also, for example, in the present embodiment, a case of using the telephone line 210 as a public line has been given, but the present invention is not limited to this case, and for example, a radio communication line, the internet, or a LAN may also be used as a public line. Also, the communication terminal may be used according to the type of public line, such as a transceiver used as the communication terminal when the public line is radio communication, and a personal computer or a palmtop computer used as the communication terminal when the public line is the internet or a LAN. Therefore, constructing the digital real security system using the existing public line allows the use form of the digital real security system to be expanded and allows the construction cost of the digital real security system to be suppressed.

Also, the name of the digital real security system and method is used in the present embodiment, but this is for convenience of description, and the name may be a digital real security, a crime prevention system, a security method, and the like. In addition, the detection of an abnormal situation covers all known problems. An example of an abnormal situation is an intrusion or proximity of a suspicious person. Moreover, the report may be any report and is not limited to an email message.

Moreover, the digital real security system and method of the present invention can also be implemented by a program to operate a computer as the digital real security system or method. Such a program may be stored in a storage medium that can be read by a computer.

Such a storage medium recorded with a program may be the ROM itself of the present digital real security system, or may be a storage medium such as a CD-ROM which can be read by inserting the storage medium thereinto when a program reading device such as a CD-ROM drive is provided as an external storage device.

Further, the storage medium may be a magnetic tape, a magnetic tape cartridge, a flexible disk, a hard disk, an MO/MD/DVD, or the like, or a semiconductor memory.
