In addition, when member A carrying mobile terminal 20 leaves work place C, control unit 26 (wireless tag identification information detection means 60) of mobile terminal 20 detects wireless tag 10b carried by member B and the work place. The wireless tag identification information of the wireless tag 10c placed in C is no longer detected. After determining that the work has started, the control unit 26 (the wireless tag identification information detection unit 60, the work start determination unit 51, the fourth determination unit 58, and the second warning unit 59) of the mobile terminal 20 detects the wireless tag possessed by the worker A. When the RFID tag identification information of the RFID tag 10b possessed by member B and the RFID tag 10c placed at work place C is not detected while the RFID tag identification information of 10a is being received (Yes in step S3), the member When the time count for A's withdrawal judgment and the time count for member A's temporary withdrawal judgment are started, and the time count for temporary withdrawal judgment by member A reaches a second duration that is shorter than the first duration (the state is If it continues for a second duration shorter than the first duration), it is determined that member A is temporarily leaving (Yes in step S14), the time count for temporary leaving judgment of member A is reset, and member A possesses A warning sound is emitted from the speaker 29b of the portable terminal 20 to inform the user (step S15).

Note that the control unit 26 of the mobile terminal 20 (the wireless tag identification information detection unit 60, the work start determination unit 51, and the fourth determination unit 58) determines that the work has started, and then detects the wireless tag of the wireless tag 10a possessed by the member A. During the reception of the identification information, a state occurs in which the RFID tag identification information of the RFID tag 10b possessed by worker B and the RFID tag 10c placed at work place C is not detected (Yes in step S3), and worker A decides to leave. When the time count and the time count of the temporary withdrawal judgment of member A are started, and the time count of the temporary withdrawal judgment of member A has not reached the second duration time shorter than the first duration time (the state is the first duration time If it does not continue for a second duration shorter than ), it is not determined that the member A is temporarily leaving (No in step S14), and the process returns to step S3.

Further, the control unit 26 (the wireless tag identification information detection means 60, the third determination means 56, the second information transmission means 57) of the mobile terminal 20 determines that the member A has left temporarily, and then determines that the member A has left. When the count reaches the first duration (when the duration from the occurrence of the state in which the wireless tag identification information of the wireless tag 10b and the wireless tag 10c is not detected reaches the first duration), it is determined that member A has left. (Yes in step S16), the video call information (audio data from the microphone 29a and the captured image from the camera 28) and the terminal identification information of the mobile terminal 20 are sent to the server 30 installed in the monitoring center D via the network N. Then, the server 30 connects the client terminal 40 and the mobile terminal 20 to start a video call (step S17). At the same time as the start of the video call, the control unit 26 (third determination unit 56) of the mobile terminal 20 resets the time count for determining whether member A is leaving (step S18).

FIG. 10 is a diagram schematically showing a state in which the control section 26 (third judging means 56) of the portable terminal 20 judges that the member A has left. As shown in FIG. 10, when the control unit 26 (the third determination means 56) determines that member A has left, only member B is present at work place C, and member A is at work place C. It is in a state of being outside. In this state, a warning sound is emitted from the speaker 29b of the mobile terminal 20 possessed by member A. Further, as shown in FIG. 10, a video call has been started between the client terminal 40 of the monitoring center D and the mobile terminal 20 . A supervisor E at the monitoring center D judges whether there is a possibility that an incident will occur at the work place C based on the video call. When Observer E determines that there is a possibility that something is wrong in Workplace C, depending on the situation, Observer E instructs Team Member A to return to Workplace C through video call, The guards are instructed to go straight to the work place C and deal with the problem, and if necessary, the relevant organizations such as the police and the fire department are notified.

On the other hand, the control unit 26 (RF tag identification information detection means 60, third judgment means 56, second warning means 59) of the mobile terminal 20 counts the time for the withdrawal judgment of the member A after judging that the member A is temporarily leaving. reaches the first duration (before the duration from the occurrence of the state in which the wireless tag identification information of the wireless tag 10b and the wireless tag 10c is not detected reaches the first duration) (No in step S16), the wireless When the wireless tag identification information of the tag 10b and the wireless tag 10c is detected (re-detected) (Yes in step S19), it is determined that the worker A has returned to the work place C, and the speaker 29b of the portable terminal 20 possessed by the worker A is detected. Stops the notification of the warning sound from (step S20), resets the time count for determining whether member A is leaving (step S21), and returns to step S2.

Note that the control unit 26 (the wireless tag identification information detection means 60 and the third determination means 56) of the mobile terminal 20 detects the wireless tag identification information of the wireless tags 10b and 10c after determining that the member A has temporarily left. If the wireless tag identification information of the wireless tag 10b and the wireless tag 10c is not detected (re-detected) before the duration time from the occurrence of the state of not being detected reaches the first duration time (No in step S16) (step S19 No), it is determined that member A has not yet returned to work place C, and the process returns to step S15.

It is also conceivable that the mobile terminal 20 possessed by the member A is intentionally turned off when the member A leaves. As a countermeasure against this, the controller 26 (the wireless tag identification information detection means 60 and the work start determination means 51) of the mobile terminal 20 possessed by the worker A waits for, for example, 5 Once a minute, a confirmation signal is sent to the server 30 of the monitoring center D via the second communication interface 25 and the network N, and when the server 30 detects that the confirmation signal is interrupted, the client terminal 40 is notified of an abnormality. It may be configured to display occurrences. With such a configuration, even if the portable terminal 20 is intentionally turned off, the surveillance staff E at the monitoring center D can detect it.

As described above, according to the present embodiment, it is possible to grasp the number of workers in a work place with a portable terminal by using radio waves of wireless tags without complicated processing. In addition, when working alone in a work place where working alone is prohibited, by using network communication of mobile terminals, the situation of working alone can be monitored by a supervisor at a remote location such as a monitoring center. It can be grasped in real time. As a result, it is possible to prevent workers from working alone (prevention of mistakes and risks) and to prevent illegal actions by workers.

In the present embodiment, the workers are two members A and B, but the number of workers is not limited to this, and three or more workers can be employed. In this case, the mobile terminal 20 determines that the work is started when the control unit 26 detects the wireless tag identification information of the wireless tags 10 attached to all the workers and the work place. It is determined whether or not the wireless tag identification information of the wireless tag 10 in the mobile terminal 20 is detected while the mobile terminal 20 remains alone at the work place, and depending on the determination result, an alarm sound is generated or an image is displayed with the client terminal 40. Calling or the like may be performed.

Further, in the present embodiment, the management server 30 extracts the wireless tag identification information and the mounting location of the specific wireless tag 10 from the master data of the wireless tag 10 managed by itself, based on the content of the work instruction. and the mobile terminal 20 stores it in the storage unit 21. However, it is assumed that the storage unit 21 of the mobile terminal 20 stores the predetermined wireless tag identification information and the mounting location in advance. may be configured.

In addition, in the present embodiment, the leader-level member A (first worker) possesses the mobile terminal 20, but the present invention is not limited to this. 20 may be possessed. In this case, the mobile terminal 20 of the worker B who remains at the work place C may issue a warning when it is determined that the worker A has left temporarily. Also, when it is determined that member A has left, the video call may be made between member B's portable terminal 20 and monitoring center D's client terminal 40 . In this way, it is possible to more effectively prevent either member A or B from working alone at work place C.

In the present embodiment, a fixed place such as a vault is taken as an example of the work place C. The driver's cab may be targeted. Furthermore, by linking the mobile terminal with the cruise control device of the vehicle and restricting the operation of the linked cruise control device unless the mobile terminal determines that both members A and B are in the cab of the vehicle. , the vehicle may be prevented from running. In this way, the vehicle in which valuables are managed in the luggage compartment can of course be hijacked and driven by a third party other than members A and B, and can also be driven by either member A or B alone. can be deterred.

Further, in the present embodiment, the wireless tag of the BLE communication standard has been described as an example of the transmitter, but the transmitter is not limited to this. Other communication means may be used as the transmitter as long as it is a device that transmits identification information or the like. For example, contactless wireless (NFC: Near Field Communications), RFID, ultrasonic waves, light, or the like may be used.

Further, in the present embodiment, the control unit 26 of the mobile terminal 20 is configured to determine whether the worker is leaving or the like, and to sound an alarm or start a video call with the client terminal 40 according to the determination result. However, based on the detection information received by the server 30 from the mobile terminal 20, the server 30 determines whether the worker holding the mobile terminal 20 and other accompanying workers have left the work place, etc. In response, the server 30 sends a warning sound instruction to the portable terminal 20, and the portable terminal 20 is configured to sound a warning sound based on the instruction. to send an instruction to the mobile terminal 20 to transmit the video call information, and the mobile terminal 20 transmits the video call information to the server 30 based on the instruction to start the video call. You may
