In addition, the control unit 20 is provided with various functions for executing the notification control unit 30 by executing the notification management program recorded in the recording device 22. When receiving the emergency notification signal from the portable security device 10 described later, the notification control unit 30 assigns the notification destination (the receiver terminal 12) associated with the identification information recorded in the notification management data 32 described later. On the other hand, a notification (emergency notification) that the holder of the mobile security device 10 is in an emergency state is issued.

The recording device 22 is, for example, a hard disk drive or a non-volatile memory, and stores a report management program for executing a report management service, and report management data 32 for storing information necessary for report management. Although the report management program is installed in the recording device 22 in advance, the report management program may be downloaded from the external server by the communication unit 24.

FIG. 3 shows an example of the notification management data 32, which is identification information of the portable security device 10 (for example, the identification number of the owner, the device serial number, the MAC address, the telephone number) and the notification of the emergency information. Information of the report destination such as the destination (the telephone number and the mail address of the holder of the receiver terminal 12) and the information of the number of reports are recorded in association with each other.

The information on the number of notifications is a count of the number of notifications to the receiver terminal 12 during a certain period, and the notification control unit 30 automatically notifies the police when the number of notifications reaches a predetermined value (for example, 3 times). Is configured to make a report.

In FIG. 2, the memory 26 is composed of a ROM and a RAM, and reads the system program for starting the notification management server 14 and the notification management program stored in the recording device 22 to execute the emergency notification service described later. The communication unit 24 transmits/receives data to/from the portable security device 10 and the receiver terminal 12 through the communication network 16.

As shown in FIG. 4, the portable security device 10 is a portable terminal, is attached to the body of the holder, and measures the heart rate of the holder. In order to measure the heart rate with high accuracy, the portable security device 10 is preferably configured to be attached so as to be in close contact with the arm (eg, upper arm) of the holder. In this case, the portable security device 10 is hidden by the sleeve of the jacket and cannot be visually recognized from the outside. Alternatively, the mobile crime prevention device 10 is a watch-type terminal such as a smart watch, and is attached so as to be in close contact with the arm of the holder, and is used as a watch in a normal state (a state where no emergency occurs). You may be able to.

As shown in FIG. 5, the mobile security device 10 includes a control unit 40, a recording device 42, a position sensor 44, a heart rate sensor 46, an imaging unit 48, a timer 50, a communication unit 52, and a memory 54. In addition to the above-described configuration, the mobile crime prevention device 10 may be configured to have, for example, a call function and an operation input function. These functions are driven by a secondary battery (not shown).

The control unit 40 centrally controls the operation of the mobile security device 10, and executes various functions of the mobile security device 10 by executing a system program stored in the memory 54. Further, the control unit 20 is provided with various functions for executing the notification determination unit 56 described later by executing the notification determination program recorded in the recording device 22.

The recording device 42 is, for example, a non-volatile memory, and shows a notification determination program for determining an emergency notification, notification data 58 for recording information related to the notification, and a temporal change in the heart rate of the holder. Heart rate data 60 and are recorded. Although the notification determination program is installed in the recording device 42 in advance, the communication management unit 52 may be configured to download the notification management program from an external server.

The position sensor 44 is, for example, a GPS sensor, and acquires information on the current position of the mobile security device 10 at regular intervals. In an emergency described later, the acquired current position information is recorded in the recording device 22 as the notification data 58.

The heart rate sensor 46 is, for example, an optical sensor, and measures the heart rate by irradiating the body (wrist or the like) with light at regular time intervals and detecting changes in blood flow accompanying heartbeat. The measured heart rate data is recorded in the recording device 22 as heart rate data 60.

The image pickup unit 48 is composed of, for example, an image pickup element and an image processing circuit, and generates image data of a subject by photographing a subject such as a person or a background and performing image processing. The image data obtained by photographing is recorded in the recording device 42 and is appropriately used by the holder of the portable security device 10. In an emergency described later, the subject is automatically photographed and the obtained image data is recorded in the recording device 42 as notification data.

The timer 50 measures the current time of the portable security device 10 and the measurement time of the heart rate of the holder, and sends it to the notification determination unit 56 of the control unit 40. The communication unit 52 transmits/receives data to/from the receiver terminal 12 and the notification management server 14 via the communication network 16.

The memory 54 includes a ROM and a RAM, stores various programs and setting data for controlling basic operations (imaging, communication, etc.) of the mobile security device 10, and is read by the control unit 40 when the mobile security device 10 is activated. ..

The notification determination unit 56 monitors the heart rate of the holder measured by the heart rate sensor 46, and determines that the holder has an emergency when the change in the heart rate satisfies a predetermined condition.

FIG. 6 shows an example of changes in the heart rate when a person in a restrained state holds his/her breath as an example of an emergency state. When the person is restrained at time T1, the heart rate of the person rapidly increases. After that, when the person intentionally holds his/her breath at time T2 when, for example, 10 seconds or more has elapsed, the heart rate that had been increasing up to then rapidly decreases, for example, 10 seconds or more have elapsed. The minimum value is reached at time T3. As described above, the present embodiment utilizes that the heart rate once rises when an emergency occurs, and then the heart rate falls when the holder intentionally holds his/her breath.

The notification determination unit 56 detects that the heart rate measured by the heart rate sensor 46 continuously increases for a predetermined time (for example, 10 seconds), and then decreases for a predetermined time (for example, 10 seconds). Therefore, it is determined that the holder of the mobile crime prevention device 10 is in a tense state such as restraint and intentionally holds his/her breath in order to ask for rescue, and the report management server 14 receives a notification signal (rescue Signal).

In FIG. 1, the receiver terminal 12 is, for example, a communicable information processing device such as a mobile phone, a tablet terminal, a personal computer, or a smartphone, and is owned by a guardian, for example. An emergency call program (so-called “app”) for receiving information from the report management server 14 and displaying it on the screen is installed in the receiver terminal 12, and the mobile crime prevention device 10 made an emergency call. At this time, it is configured to display the current position of the mobile security device 10 and the captured peripheral image. The emergency call program can be installed in the receiver terminal 12 by downloading it from an external server.

Prior to using this notification system, the emergency notification program is activated on the receiver terminal 12, the identification number (device number) of the mobile security device 10 is set, and the receiver terminal 12 and the mobile security device 10 are paired. To ring. As a result, the emergency call from the portable security device 10 reaches the specific receiver terminal 12.

FIG. 7 shows an example of a processing procedure of the notification determination in the mobile security device 10. First, in the portable security device 10, the heart rate sensor 46 measures the heart rate of the holder and the timer 50 measures the measurement time (step S10). Then, the notification determination unit 56 determines whether or not the heart rate measured by the heart rate sensor 46 continuously increases for a predetermined time (10 seconds) (step S11). If the heart rate has not increased, or if it has increased but has not continued for 10 seconds, the process returns to step S10, and the heart rate of the holder is measured again.

On the other hand, when it is determined that the heart rate continuously increases for 10 seconds, the notification determination unit 56 drives the timer 50 to measure the time in order to determine whether the holder has held his/her breath. (Step S12), the heart rate sensor 46 measures the heart rate of the holder (step S13). The notification determination unit 56 determines whether or not the heart rate measured by the heart rate sensor 46 has continuously decreased for a predetermined time (10 seconds) (step S14).

When it is determined that the heart rate has continuously decreased for 10 seconds, the notification determination unit 56 determines that the holder is in an emergency such as restraint and holds his/her breath to ask for rescue. The position sensor 44 and the imaging unit 48 are driven to acquire the current position of the mobile crime prevention device 10 and data of the peripheral image, and the data is recorded in the recording device 42 as the notification data 58 (step S15). Then, the notification determination unit 56 transmits a rescue signal for requesting rescue to the notification management server 14 together with the notification data 58 and the identification information of the portable security device 10 (step S16).

On the other hand, in step S14, if the holder's heart rate has not decreased, or if the heart rate has decreased but has not continued for 10 seconds, the notification determination unit 56 starts measurement in step S12. It is determined whether a predetermined time (for example, 5 minutes) has elapsed from the time point (step S17). If the predetermined time has not elapsed in step S17, the process returns to step S14, the heart rate is measured, and it is again determined whether or not the notification condition is satisfied.

On the other hand, when it is determined in step S17 that the predetermined time has elapsed, the notification determination unit 56 determines that the holder of the mobile crime prevention device 10 is not in an emergency state, returns to step S10, and the heart beat of the holder again. Counting is done. Accordingly, it is possible to prevent unnecessary notification from being made when there is no emergency (for example, when the holder is exercising).

FIG. 8 shows the procedure of the notification process in the notification management server 14. The notification control unit 30 of the notification management server 14 determines whether or not a rescue signal has been received from the portable security device 10 (step S20). When the notification control unit 30 receives the rescue signal, the notification control unit 30 extracts the identification information of the portable security device 10 included in the rescue signal and detects the corresponding notification destination information from the notification management data 32 (step S21).

Then, the notification control unit 30 reads out the notification data (position data and image data) received together with the rescue signal, and transmits the notification data to the receiver terminal 12 corresponding to the notification destination detected in step S21 (step S22). ..

An example of the emergency call displayed on the receiver terminal 12 is shown in FIG. On the screen 62 of the receiver terminal 12, a message indicating that the mobile security device 10 is in an emergency state such as "emergency SOS", a map image 64 showing the current position of the mobile security device 10, and a captured image 66 around the mobile security device 10. And are displayed side by side. Also, a slide bar 68 for notifying the police may be displayed together. As a result, it is possible to reliably notify the receiver terminal 12 corresponding to the mobile crime prevention device 10 of the emergency.

In FIG. 8, the notification control unit 30 updates the notification management data 32 by adding 1 to the number of notifications to the receiver terminal 12 (step S23), and then the updated number of notifications is a predetermined value (for example, 3 times). (Step S24), and if it has reached three times, an emergency call is made to the police (step S25). It should be noted that an emergency call may be made to the notification destination separately registered in the receiver terminal 12. As a result, even when the original user of the receiver terminal 12 cannot confirm the emergency call, it is possible to deliver the emergency call to an appropriate call destination.

On the other hand, in step S25, when the number of notifications within the predetermined period from the notification start time has not reached the predetermined value, the process returns to step S20, and it is determined again whether or not the rescue signal is received.

In the above embodiment, although an emergency call is made via the notification management server, contact information (telephone number, mail address) of the receiver terminal 12 is stored in the mobile security device 10, and the mobile security device is stored. The emergency notification may be directly issued from 10 to the receiver terminal 12.

In the above embodiment, the emergency call is issued when it is detected that the heart rate continuously increases for a certain period (for example, 10 seconds) and then decreases, but the certain period is limited to 10 seconds. Instead, it can be set appropriately. Further, it is not always necessary to continuously increase for a certain period of time, and for example, the increase of the heart rate during a certain period exceeds a predetermined value (for example, 40 times within 10 seconds), and then the decrease of the heart rate during the certain period. An emergency call may be issued when the value exceeds a predetermined value.

As described above, according to the mobile crime prevention device 10, the emergency situation is detected based on the increase/decrease in the heart rate. Therefore, even if you are physically and situationally facing an emergency (for example, your limbs are restrained), you can send a signal requesting rescue to your terminal by simply holding your breath. .. Further, by attaching the portable security device 10 to the upper arm, it is possible to accurately measure the heartbeat, and it is possible to prevent the heartbeat from being recognized from the outside by being covered by the sleeve.

(Second embodiment)
The second embodiment described below uses the position sensor 44 as well as the heart rate sensor 46 to more accurately determine an emergency situation.

In the present embodiment, information on a range in which the holder is supposed to move (hereinafter, referred to as a movement expected range) is set in advance. Then, if the position information detected after the holder's heart rate has increased or decreased is outside the movement expected range, it is highly likely that the holder has been taken away, and it is determined that the situation is an emergency. On the other hand, if the position information is within the movement expected range, there is a high possibility that it is a malfunction, and thus it is not determined that the situation is an emergency. The details will be described below.

There are various possible methods for setting the assumed movement range. For example, the emergency call program installed in the receiver terminal 12 has a function of setting the expected movement range. With the setting function, a map is displayed when the home address is registered. Then, an arbitrary range can be set from the displayed map. With the same setting function, the school that the owner goes to may be registered and set within a predetermined range from the school, or within the school district as a movement expected range.

The determination as to whether the movement is within the expected movement range or outside the expected movement range may be performed by the mobile security device 10, the notification management server 14, or the receiver terminal 12. ..

When the mobile crime prevention device 10 determines whether the movement is within the movement expected range or outside the movement expected range, the set movement expected range is registered in the mobile crime prevention device 10 from the receiver terminal 12. Then, if the current position acquired in step S15 in the notification determination process of the mobile security device 10 shown in FIG. 7 is outside the movement expected range, the notification determination unit 56 of the mobile security device 10 sends a rescue signal to the notification management server 14. It is transmitted (step S16). On the other hand, if the current position is within the movement expected range, the notification determination unit 56 does not transmit the rescue signal to the notification management server 14.

When the notification management server 14 determines whether it is within the expected movement range or outside the expected movement range, the set expected movement range is registered in the notification management server 14 in association with the identification information of the portable security device 10. .. In this case, the operation of the mobile security device 10 may be as shown in FIG. 7, but in step S16, in addition to the rescue signal, the position information detected in step S15 (that is, the current position of the mobile security device 10) is also reported and managed. Send to the server 14. Then, if the current position of the mobile security device 10 is outside the movement expected range associated with the identification information extracted in step S21 in the notification processing of the notification management server 14 illustrated in FIG. 8, the notification control unit of the notification management server 14 30 transmits the report data to the receiver terminal 12 (step S22). On the other hand, if the current position of the mobile crime prevention device 10 is within the expected movement range, the notification control unit 30 does not transmit the notification data to the receiver terminal 12.

When the receiver terminal 12 determines whether it is within the movement expected range or outside the movement expected range, the operation of the mobile crime prevention device 10 may be as shown in FIG. 7, but in step S16, in addition to the rescue signal, The position information detected in step S15 is also transmitted to the notification management server 14. Further, the operation of the notification management server 14 may be as shown in FIG. 8 (however, steps S23 to S25 may be omitted), but in step S22, in addition to the notification data, position information from the portable security device 10 (that is, , The current position of the mobile security device 10) is also transmitted to the receiver terminal 12. Then, the receiver terminal 12 that has received the notification data from the notification management server 14 displays a screen as shown in FIG. 9 if the current position of the portable security device 10 is outside the assumed movement range. On the other hand, if the current position of the mobile crime prevention device 10 is within the movement expected range, the screen as shown in FIG. 9 is not displayed or the notification data is issued within the movement expected range.

As described above, the emergency situation can be determined with higher accuracy by using the current position of the mobile crime prevention device 10.

In each of the above-described embodiments, after the heart rate of the holder of the mobile crime prevention device 10 increases, a decrease in the heart rate due to breath holding is detected and an emergency call is issued. The determination unit 56 may combine other sensors (detection means) to determine the emergency.

For example, a mobile security device 10 is provided with a push button, and after the owner's heart rate is increased/decreased, an emergency call is issued by operating a push button separately provided in the mobile security device 10. May be. Alternatively, a microphone is provided in the mobile security device 10, and an emergency call is issued when the volume level exceeds a predetermined value after the heart rate of the holder has increased/decreased (for example, when a loud voice or a scream is emitted). You may do it.

In addition, the portable security device 10 is provided with a humidity sensor, the sweat rate of the holder is measured from the difference with the air humidity near the skin, and the change in the sweat rate measured after the heart rate of the holder increases/decreases. May be configured to issue an emergency call when exceeds a predetermined value. Further, the portable security device 10 may be provided with a temperature sensor so that an emergency call is issued when the change in body temperature exceeds a predetermined value after the heart rate of the holder has increased/decreased.

Further, when an acceleration sensor is provided in the mobile crime prevention device 10 and a rapid acceleration change is detected after the heart rate of the holder increases/decreases (for example, the holder of the mobile crime prevention device 10 rapidly changes his/her arm a plurality of times). It may be configured so that an emergency call is issued even when the device is shaken.

These detecting means may be combined appropriately.

In the above embodiment, the mobile security device 10 is configured to issue an emergency call. However, in addition to this, for example, an emergency call is issued and the mobile security device 10 receives a call from the receiver terminal 12 (preset incoming call). It may be configured to automatically call the destination). As a result, the user (for example, the parent) of the receiver terminal 12 can grasp the situation from the sound heard from the mobile crime prevention device 10.

The above-described embodiments are described for the purpose of enabling a person having ordinary knowledge in the technical field to which the present invention belongs to implement the present invention. Various modifications of the above-described embodiment can be naturally made by those skilled in the art, and the technical idea of the present invention can be applied to other embodiments.
