Description

  The present invention relates to a security system for detecting a suspicious person, and an alarm device and a user terminal used therefor, and more specifically, a security system for detecting a suspicious person who does not have a certain user terminal and the same. The present invention relates to an alarm device and a user terminal used.

As a conventional security system, there is a system in which an authentication gate using an IC card is provided at an entrance or the like so that only authenticated persons can enter the room (see Patent Document 1).
JP-A-4-109308

  Such a conventional security system requires an authentication gate for authenticating the IC card. However, such a security system using authentication with an IC card is difficult to use in places such as schools where entrances and exits are wide, there are multiple entrances, and entrances are frequently performed. For example, in places like school, suspicious people may invade from the ground. However, the intrusion route to the ground is not limited to a place where an authentication gate is provided as an entrance such as a school gate. Furthermore, if a suspicious person has already entered the facility by some method, the conventional security system cannot warn of the presence of the suspicious person. For example, let us consider a case where a legitimate person uses an IC card to enter the facility and the suspicious person enters the facility without being noticed at the moment when the entrance is open. In this case, since the suspicious person has passed through the authentication gate, the security system cannot recognize the suspicious person thereafter. Especially in places such as schools, even if there is an IC card authentication gate at the doorway, there is an opportunity for a suspicious person to enter the school in some way, hide in an inconspicuous place, and conduct fraud It is also possible to meet.

  If there is already no one in the facility (for example, if all students, students, faculty, etc. have returned home from the school), the security system using the human sensor will be activated and the suspicious person will enter the school. You can also warn you. However, since such a security system cannot distinguish a legitimate person from a suspicious person, for example, such a security system cannot be operated during the day.

  Therefore, an object of the present invention is to provide a security system capable of alarming an abnormality when a suspicious person enters a predetermined space even if a legitimate person can enter and exit.

  In order to solve the above problems, the present invention has the following features. The present invention is a security system for detecting a suspicious person, and includes an alarm device for detecting a suspicious person and a user terminal possessed by a legitimate person and capable of communicating with the alarm device. The alarm device includes: a person detection unit that detects whether a person has entered a predetermined space; and an identification ID request that requests the user terminal to transmit an identification ID when the person is detected by the person detection unit. Based on the collation result by the identification ID collating unit, the identification ID receiving unit that receives the identification ID transmitted from the user terminal, the identification ID receiving unit that collates the identification ID received by the identification ID receiving unit, Determining means for determining whether the person sensed by the person sensing means is a legitimate person or a suspicious person. The user terminal includes an identification ID transmitting means for transmitting the stored identification ID when the alarm device requests transmission of the identification ID.

  According to the present invention, when a person is detected in a predetermined space, the alarm device requests transmission of an identification ID. In response to the request, the user terminal returns an identification ID. If the person who has entered the predetermined space is a legitimate person, he / she has the user terminal and is not judged to be a suspicious person by the alarm device. On the other hand, if the person who has entered the predetermined space is a suspicious person, he / she does not have a user terminal, or even if he / she has one, the identification ID is not registered. It is judged that Therefore, if a suspicious person enters a predetermined space where no one is present, the alarm device alerts the suspicious person to enter. As a result, a security system capable of alarming an abnormality when a suspicious person enters a predetermined space even when a legitimate person can enter and exit, and an alarm device and a user terminal used therefor are provided. It becomes.

  These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The control device 5 can transmit and receive electrical signals to and from the human sensor unit 3 and the wireless communication unit 4. The control device 5 may be disposed near the human sensor unit 3 and the wireless communication unit 4 or may be disposed far away. The control device 5 is connected to an external network. When an abnormality occurs, the control device 5 emits an alarm sound and notifies the external computer device (not shown) of the abnormality via the external network. The human sensor unit 3 can detect the presence or absence of a person such as an infrared sensor. The wireless communication unit 4 enables wireless communication between the control device 5 and the user terminal 2 using a wireless communication method such as Bluetooth (registered trademark). In FIG. 1, the human sensor unit 3 and the wireless communication unit 4 are described adjacent to each other, but may be installed apart in consideration of a human detection distance and a communicable distance. Further, although the human detection sensor unit 3 and the wireless communication unit 4 are associated one-on-one, a plurality of wireless communication units 4 may be disposed in association with one human detection sensor unit 3. On the contrary, a plurality of human sensor units 3 may be arranged in association with one wireless communication unit 4. In FIG. 1, the control device 5 is provided corresponding to the human detection sensor unit 3 and the wireless communication unit 4, but a plurality of human detection sensor units 3 and a plurality of wireless communication units 4 are provided. In contrast, one control device 5 may be provided.

  FIG. 2 is a block diagram illustrating a functional configuration of the alarm device 1. 2, parts having the same functions as those shown in FIG. 1 are given the same reference numerals. In FIG. 2, the alarm device 1 includes a control unit 6, a storage unit 7, an external communication unit 8, an output unit 9, a human sensor unit 3, and a wireless communication unit 4. A control device 5 is configured by the control unit 6, the storage unit 7, the external communication unit 8, and the output unit 9. The control unit 6 is connected to an external network via the external communication unit 8 and can communicate with an external computer device (not shown). The external communication unit 8 is a device that can transmit a signal from the control unit 6 and receive a signal from the external network in accordance with a communication protocol in the external network. The output unit 6 is a speaker, a light, a display, or the like. When an abnormality occurs, the control unit 6 causes the output unit 9 to execute an output indicating the abnormality. For example, if an abnormality occurs, the control unit 6 causes the output unit 9 to output a loud alarm sound. When the output unit 9 notifies the abnormality with sound or light, the output unit 9 may be provided in a management room or the like, or may be provided near the human sensor unit 3 or the wireless communication unit 4. good. When the output unit 9 is provided near the human detection sensor unit 3 or the wireless communication unit 4, the output unit 9 and the human detection sensor unit 3 or the wireless communication unit 4 may correspond one-to-one. The storage unit 7 is a recording device such as a memory or a hard disk. The storage unit 7 stores the identification ID of the registered user terminal 2. The control unit 6 and the storage unit 7 may be connected via a network. The control device 5 may be realized by dedicated hardware, or may be realized by a general-purpose computer device in which a program for executing an operation shown in FIG.

  FIG. 3 is a block diagram showing a functional configuration of the user terminal 2. In FIG. 3, the user terminal 2 includes a storage unit 10, a control unit 11, and a wireless communication unit 12. Note that the user terminal 2 may be realized as part of general-purpose hardware such as a mobile phone, or may be realized as dedicated hardware. When the user terminal 2 is realized as a part of general-purpose hardware, a program for executing an operation shown in FIG. 5 described later is stored in the storage unit 10, and the CPU of the hardware functions as the control unit 11. The program may be executed. The storage unit 10 is a recording device such as a memory or a hard disk. The storage unit 10 stores an identification ID assigned to the user terminal 2. Similarly to the wireless communication device 4, the wireless communication device 12 uses a wireless communication method such as Bluetooth (registered trademark), and enables wireless communication between the control device 5 and the user terminal 2.

  FIG. 4 is a flowchart showing the operation of the alarm device 1. Hereinafter, the operation of the alarm device 1 will be described with reference to FIG. First, based on the signal from the human sensor unit 3, the controller 6 determines whether or not a human has entered a predetermined space by the human sensor unit 3 (step S101). If no person is detected, the control unit 6 continues the operation of step S101 as it is. On the other hand, when a person is detected, the control unit 6 proceeds to the operation of step S102.

  In step S <b> 102, the control unit 6 causes the wireless communication unit 4 to transmit a signal (identification ID request signal) requesting transmission of the identification ID. Next, the control unit 6 determines whether or not a predetermined time has passed (step S103). If the predetermined time has not elapsed, the operation proceeds to step S104. On the other hand, if the predetermined time has elapsed, the operation proceeds to step S108.

  In step S <b> 104, the control unit 6 determines whether or not the wireless communication unit 4 has received the identification ID from the user terminal 2. If the identification ID has not been received, the control unit 6 returns to the operation of step S103. On the other hand, when the identification ID is received, the control unit 6 proceeds to the operation of step S105. In step S <b> 105, the control unit 6 refers to the storage unit 7 and checks whether or not the received identification ID matches the registered identification ID. As a result of the collation, the control unit 6 determines whether or not the authentication of the identification ID is completed, that is, whether or not the matching identification ID is stored in the storage unit 7 (step S106). When the authentication is completed, the control unit 6 proceeds to the operation of step S107, and recognizes that the person detected by the person detection sensor unit 3 is a valid person. On the other hand, if the authentication has failed, the control unit 6 proceeds to the operation of step S108.

  In step S108, the control unit 6 warns that the intruder is a suspicious person. For example, the control unit 6 causes the output unit 9 to output a sound, emit a light, display an abnormality on the display, or cause an abnormality to an external computer device (not shown) via the external communication unit 8. Alert the suspicious person intrusion by reporting.

  FIG. 5 is a flowchart showing the operation of the user terminal 2. Hereinafter, the operation of the user terminal 2 will be described with reference to FIG. First, the control unit 11 determines whether an identification ID request signal has been received based on a signal from the wireless communication unit 12 (step S201). If the identification ID request signal has not been received, the control unit 11 returns to the operation of step S201. On the other hand, when receiving the identification ID request reception, the control unit 11 reads the identification ID of the own terminal stored in the storage unit 10 and causes the wireless communication unit 12 to transmit a signal corresponding to the identification ID, Returning to the operation of step S201.

  Thus, according to the present embodiment, when a person is detected in a predetermined space, the alarm device 1 requests transmission of an identification ID. In response to the request, the user terminal 2 returns an identification ID. If the person who has entered the predetermined space is a legitimate person, since the user terminal 2 is possessed, the alarm device 1 does not determine that the person is a suspicious person. On the other hand, if the person who has entered the predetermined space is a suspicious person, he / she does not have the user terminal 2 or even if he / she has the identification ID in the storage unit 7, the alarm device 1 Therefore, it is determined that a suspicious person has entered. Therefore, if a suspicious person enters into a predetermined space where no one is present, the alarm device 1 warns that the suspicious person has entered.

  In addition, when using this embodiment, when there are a plurality of people in a predetermined space, if there is one legitimate person, even if a suspicious person is mixed in it, an identification ID will be returned, Suspicious person intrusion is not reported. However, when there are a plurality of persons in a predetermined space and there is only one legitimate person, the legitimate person should be aware of the existence of a suspicious person. Does not occur. In particular, the security system according to the present embodiment functions effectively when there is no suspicious person (for example, a toilet or a warehouse, an audiovisual facility, a stair landing, an outdoor shade). . In such a case, if the security system of this embodiment is used, the alarm device 1 can recognize the presence of a suspicious person, but does not warn of an abnormality when a legitimate person enters.

  Although the security system according to the present embodiment frequently enters and exits people such as schools, public offices, company buildings, homes, etc., usually suspicious persons are allowed to enter and exit only specific persons. It is possible to detect that it is intruding. The security system according to the present embodiment is particularly effective for use in such a place.

  Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

  The security system and the alarm device and user terminal used therefor can detect a suspicious person who does not have a certain user terminal, and is industrially useful.
