  The radio unit 24 includes a base station communication unit and a GPS receiving unit. The base station communication unit is a mobile communication unit that performs wireless communication with the mobile communication base station 16. The communication device 2 is monitored by the base station communication unit via the mobile communication base station 16 and the communication network 8. Communication with the center device 6 of the center 14 is possible. The GPS receiver receives a GPS signal from a GPS satellite and acquires GPS information corresponding to its current position.

  The operation unit 26 is an input means for the user to select the operation of the communication device 2 and to give an instruction to the control unit 20, and includes, for example, various button switches and a touch panel.

  The camera 28 is an imaging unit that images a subject such as a person or a landscape. The microphone 30 is a sound collection unit that collects a user's voice or the like during voice communication. The speaker 32 is a voice output unit that outputs the voice of the other party during voice communication, or outputs a ringing tone when an incoming call is received or an e-mail is received. The display unit 34 is an image display unit such as a liquid crystal display. The vibration motor 36 provides a vibrator function for vibrating the communication device 2.

  The wireless unit 24, the operation unit 26, the camera 28, the microphone 30, the speaker 32, the display unit 34, and the vibration motor 36 are connected to the control unit 20 and operate upon receiving a signal from the control unit 20, or send signals to the control unit 20. Is output.

  The control unit 20 is configured using a microprocessor or the like, and performs various processes according to a program to be executed. For example, the control unit 20 functions as a communication control unit 40, an emergency determination unit 42, a mode setting unit 44, an emergency signal transmission unit 46, and a transmission history protection unit 48.

  The communication control unit 40 constitutes a communication unit that performs a voice communication function and an Internet connection function together with the wireless unit 24. Specifically, in voice communication, a line connection is established with a call partner terminal, and a voice signal converted into an electric signal by the microphone 30 is input to the wireless unit 24 via the communication control unit 40 and wirelessly transmitted. It is converted into a radio signal by the unit 24 and transmitted to the mobile communication base station 16. The radio signal received from the mobile communication base station 16 is detected by the radio unit 24, and the extracted audio signal is input to the speaker 32 via the communication control unit 40 and the audio output circuit.

  The emergency determination unit 42 determines whether the terminal operation by the user is a predetermined emergency operation. For example, the emergency operation can be input of a personal identification number or a password, or a touch on an emergency operation button or icon displayed on the touch panel. When the personal identification number or password is used, the emergency determination unit 42 is displayed, for example, when a call origination operation is performed on the communication device 2 or when creation of a transmission mail is selected from the e-mail operation menu. The display is displayed on the unit 34, and the user is requested to input a password or the like from the touch panel. In addition, biometric information such as a fingerprint can be used as information for determining an emergency operation.

  The mode setting unit 44 controls the communication unit to set a mode for whether or not transmission is permitted by the user. There are two types of modes to be set, one is a prohibit mode for prohibiting outgoing calls and e-mails, and the other is a permission mode for permitting outgoing calls. The mode setting unit 44 normally sets the communication device 2 to the prohibit mode, and switches to the permission mode when an emergency operation is performed.

  The emergency signal transmission unit 46 transmits an emergency signal to the center device 6 when an emergency operation is performed. The emergency signal is basically a signal for notifying that an emergency operation has been performed in the communication device 2. Here, the monitoring center 14 grasps which of the plurality of communication devices 2 to be managed has undergone an emergency operation. Therefore, the emergency signal can include information for identifying the communication device 2 as the transmission source. For example, when the communication device 2 is connected to the center device 6 via a telephone line, the center device 6 can identify the communication device 2 that has transmitted the emergency signal by its caller number. In such a case, the identification information of the communication device 2 may not be included in the emergency signal.

  The outgoing call history protection unit 48 prohibits the user from operating the communication device 2 to delete the outgoing call history of telephones and e-mails.

  The storage unit 22 is realized by a memory device such as a ROM (Read Only Memory) or a RAM (Random Access Memory), and stores various programs executed by the control unit 20 and necessary data. In particular, the storage unit 22 has emergency operation information 50 and center device address information 52 registered in advance. The emergency operation information 50 is information that defines an emergency operation, and is used when the emergency determination unit 42 determines whether the terminal operation by the user is an emergency operation. For example, the above-described personal identification number and password are stored in the storage unit 22 as emergency operation information 50. The center device address information 52 is a telephone number or an IP address of the center device 6. The storage unit 22 is a transmission history storage unit that records a transmission history 54 by the user.

  The center device 6 is installed in a monitoring center operated by a security company or the like to monitor a monitoring area. In addition, the center equipment is installed in facilities that manage guards, such as the security headquarters that dispatches security guards, the command headquarters for issuing instructions to the guards remotely, and the disaster prevention headquarters installed in the disaster prevention center in a large building May be.

  FIG. 3 is a schematic block diagram of the center device 6. The center device 6 is a so-called server, and is connected to the communication network 8 and communicates with the communication devices 2 and 4 carried by the guards, a display device such as a liquid crystal display, a keyboard, a mouse, and the like. , An informing unit including a buzzer, an LED, and the like, and a control unit 92 and a storage unit 94 that control these units. When the center device 6 receives an emergency signal from the communication device 2, the center device 6 notifies the monitoring staff of the information of the communication device 2 that has transmitted the signal through the notification unit and the display device. At this time, the control unit 92 records the emergency signal reception history 96 in the storage unit 94. The supervisor of the center device 6 notified of the emergency situation contacts the communication device 2 carried by other guards and dispatches other guards to the guards who encountered the emergency situation. Instruct on-site confirmation and appropriate action.

  Next, the operation of the present system when the security guard 10 encounters an emergency and makes a call from the communication device 2 to another communication device such as the communication device 4 will be described with reference to the processing flow diagram shown in FIG. FIG. 4 is a schematic process flow diagram of the control unit 20 when the guard 10 makes a call from the communication device 2.

  When the security guard 10 makes a call operation to make a call or send an e-mail, the emergency determination unit 42 displays, for example, a screen requesting the user to perform an emergency operation on the display unit 34 to perform the emergency operation. Wait (S60).

  When the guard 10 performs a terminal operation, the emergency determination unit 42 determines whether or not the operation is an emergency operation defined by the emergency operation information 50 (S62). For example, when the emergency operation is an input of a password, the emergency determination unit 42 collates the number input by the security guard 10 with the password stored as the emergency operation information 50. When the emergency operation information 50 matches (Yes in step S62), the mode setting unit 44 switches the communication device 2 from the prohibit mode to the permit mode (S64), and the emergency signal transmitter 46 transmits an emergency signal. Is transmitted to the center device 6 (S66).

  When the center device 6 receives the emergency signal, the center device 6 records the reception history 96 including the reception time and the identification information of the communication device 2 as the transmission source in the storage unit 94 and notifies the monitoring staff through the notification unit and the display device. The GPS information acquired by the GPS receiver of the radio unit 24 is included in the emergency signal and transmitted to the center device 6. The center device 6 records the GPS information in the reception history 96 and outputs it to the notification unit and the display unit. May be.

  When the emergency signal transmitter 46 transmits an emergency signal, the mode setting unit 44 activates a timer for measuring a predetermined time (S68). For example, the timer time is set to 10 minutes. When the set time has elapsed (in the case of “Yes” in S70), the mode setting unit 44 returns the communication device 2 from the permission mode to the prohibition mode (S72).

  The mode setting unit 44 may be configured to return to the prohibit mode at the timing when the end of the telephone call made by the security guard 10 or the transmission of an e-mail is detected after the permission mode is set. Further, in the configuration using the timer, the return to the prohibit mode may be performed at the earlier timing of the time-up of the timer and the detection of the end of the call or the mail transmission.

  In another configuration, when the center device 6 transmits a mode return signal to the communication device 2 and the mode setting unit 44 receives the mode return signal, the mode setting unit 44 may switch from the permitted mode to the prohibited mode. In this configuration, the center device 6 can set the time limit of the permission mode to a different length depending on, for example, the time zone of the day. The set time limit is notified from the center device 6 to the communication device 2 when the communication device 2 and the center device 6 are in communication connection for emergency signal transmission, and the control unit 20 notifies the display unit 34 of the time limit. Display time. As a result, the security guard 10 can recognize the given communication permission time and take care to finish the telephone call or the like within the time. When the time limit is reached, the center device 6 transmits a mode return signal to the communication device 2. When the center device 6 tries to connect to the communication device 2 to transmit the mode return signal and fails to connect, for example, the center device 6 repeatedly attempts to transmit the mode return signal at predetermined time intervals.

  In the present embodiment, the destination, call time (or call end time) or e-mail body of the communication device 2 is recorded in the transmission history 54, and the transmission history protection unit 48 prevents the transmission history 54 from being erased or falsified. Although it is protected, the transmission history may be further recorded in the center device 6. In the configuration, for example, the destination transmitted by the communication device 2 when the call or the e-mail transmission is completed, the call time is transmitted to the center device 6 if it is a phone call, and the text and subject are transmitted to the center device 6 if it is an e-mail. The device 6 records the transmission history in the storage unit 94 in association with the emergency signal reception history 96. In the configuration in which the center device 6 transmits the mode return signal, the call is within the time limit or the time limit is exceeded based on the time when the mode return signal can be transmitted to the communication device 2. The center device 6 records this in the storage unit 94.

  As described above, restrictions are placed on outgoing calls from the communication apparatus 2, but no restrictions are placed on incoming calls to the communication apparatus 2. By restricting outgoing calls during normal times and permitting emergency calls when emergency calls are required, such as when an emergency situation occurs, unnecessary emergency calls can be suppressed, and the chances of information leakage are reduced. In addition, the security guard 10 is required to perform an emergency operation when making a call, the reception of an emergency signal is recorded at the center device 6, or the call time is limited, so that an action or information is issued to the outside. It is expected that attention will be paid to the situation of the place where the person is trying to make a call, and the content of the call, the presence of the surrounding people and the line of sight will be taken into consideration, and information leakage will be less likely to occur.

  Further, the communication device 2 is configured to generate sound from the speaker 32 continuously or intermittently during the period set in the permission mode, or to generate vibration by driving the vibration motor 36. You can also. With this configuration, the above-mentioned attention can be maintained even during a call or while the contents of an email are being input, which contributes to prevention of information leakage.

  In the embodiment described above, an example of restricting outgoing calls from the communication device 2 has been described. However, for emergency special numbers such as 110 (Police), 118 (Coast Guard), and 119 (Fire) As an exception, it may be possible to make an unconditional call.
