Hereinafter, embodiments of a mobile terminal, a detection method, and a program will be described in detail with reference to the accompanying drawings. Note that the embodiment described below is one embodiment of a mobile terminal, a detection method, and a program, and is not intended to limit the configuration or specifications thereof.

FIG. 1 is an explanatory diagram showing an example of the configuration of a behavior management system 1 according to the present embodiment. The behavior management system 1 according to the embodiment includes a plurality of wireless tags 10 that are transmitters, one or more mobile terminals 20, a server 30, and a client terminal 40.

The wireless tag 10 is a wireless tag that performs short-range wireless communication, for example, a BLE wireless tag based on the BLE (Bluetooth (registered trademark) Low Energy) communication standard. The wireless tag 10 transmits a signal containing wireless tag identification information, which is transmitter identification information, to one or more unspecified mobile terminals 20. The wireless tag identification information is identification information (for example, "manufacturing number") that can identify the wireless tag 10.

The wireless tags 10 are attached to workers A and B and a work location C. Team members A and B perform work such as transporting cash within work area C, which is a controlled area such as a safe where cash (valuables) is stored. The wireless tag 10 is attached to the belts of members A and B, for example. Note that the wireless tag 10 may be built into the shoes of the members A and B, or may be carried by the members A and B in advance in the form of a pendant, strap, wristband, or the like. In the example shown in FIG. 1, members A and B each carry one wireless tag 10. The wireless tag 10, which is the first transmitter, owned by Worker A (first worker) is referred to as a wireless tag 10a, and the wireless tag 10, which is the second transmitter, owned by Team Member B (second worker) is referred to as wireless tag 10b. shall be.

Further, at least one wireless tag 10 to be attached to the work place C is arranged according to the size and structure of one work place. In the example shown in FIG. 1, one wireless tag 10 is placed in the work place C. The wireless tag 10, which is the third transmitter placed at the work place C, is referred to as a wireless tag 10c.

The mobile terminal 20 is a communication device such as a smartphone, a tablet terminal, or a dedicated terminal owned by a worker. The mobile terminal 20 is a communication device that detects wireless tag identification information transmitted from the wireless tag 10. The mobile terminal 20 receives the wireless tag identification information from the wireless tag 10 with a strength of a certain level or higher, and compares it with the wireless tag identification information stored in advance. If the information matches, the mobile terminal 20 detects the wireless tag identification information of the wireless tag 10. , the detection information indicating that the wireless tag identification information of the wireless tag 10 has been detected is transmitted to the server 30 via a network N such as the Internet or a VPN (Virtual Private Network). Here, the detection information includes detected wireless tag identification information and terminal identification information that allows the mobile terminal 20 to be identified.

Furthermore, the mobile terminal 20 determines which of the predetermined states it is in according to the detection state of the wireless tag identification information of the wireless tag 10, and combines the determination result with terminal identification information that can identify the mobile terminal 20. The determination result information including the information is sent to the server 30. Further, the mobile terminal 20 performs a predetermined operation such as sounding a warning sound depending on the determination result. Since the detection state of the wireless tag 10 in the mobile terminal 20 depends on the distance between the mobile terminal 20 and the wireless tag 10, the mobile terminal 20 detects the wireless tag identification information of the wireless tag 10 attached to the work place. If it detects the wireless tag identification information of the wireless tag 10 that is inside the work place and is attached to the worker who is in possession of the mobile terminal 20, then the If the wireless tag identification information of the wireless tag 10 attached to another worker is detected, it is assumed that the wireless tag 10 is present in the vicinity of the other worker. Based on the combination of these detection states, the mobile terminal 20 determines whether all workers are present inside the work place (in this embodiment, this case is referred to as "work start"), or when any worker is present. does not exist at the work place (in this embodiment, this case is defined as the worker's "leaving" or "temporary leaving"), etc.

In this embodiment, team member A (first worker) who is a leader carries the mobile terminal 20. Team member A holds the mobile terminal 20 in his own clothing pocket.

Further, the control unit 26 (wireless tag identification information detecting means 60, first determining means 52, first information transmitting means 53) of the mobile terminal 20 determines that the member B has temporarily left, and then determines the time period for determining the withdrawal of the member B. When the count reaches the first duration time (when the duration from the occurrence of the state in which the wireless tag identification information of the wireless tag 10b is not detected reaches the first duration time), it is determined that member B has left (step S8). Yes), 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 transmitted to the server 30 installed in the monitoring center D via the network N, and the server 30 connects the client terminal 40 and the mobile terminal 20 and starts a video call (step S9). Furthermore, the control unit 26 (first determining means 52) of the mobile terminal 20 resets the time count for determining whether member B leaves the group at the same time as the start of the video call (step S10).

FIG. 9 is a diagram schematically showing a state in which the control unit 26 (first determining means 52) of the mobile terminal 20 determines that member B has left. As shown in FIG. 9, in a state where the control unit 26 (first determination means 52) determines that team member B has left, only team member A is present at work location C, and team member B is at work location C. It is in a state where it has gone outside. In this state, a warning sound is being sounded from the speaker 29b of the mobile terminal 20 owned by member A. Further, as shown in FIG. 9, a video call has started between the client terminal 40 of the monitoring center D and the mobile terminal 20. A supervisor E at the surveillance center D monitors whether an abnormality has occurred in the work place C based on the video call. When Supervisor E recognizes that something unusual has occurred in Workplace C, he may instruct the waiting guard to temporarily suspend work until Worker B returns to Workplace C, depending on the situation. In response, they are instructed to go directly to work location C and deal with the situation, and if necessary, they are notified to related organizations such as the police and fire department.

On the other hand, the control unit 26 (wireless tag identification information detection means 60, first judgment means 52, first warning means 55) of the mobile terminal 20, after determining that the member B has temporarily left, counts the time for determining the departure of the member B. Detects the wireless tag identification information of the wireless tag 10b before it reaches the first duration time (before the duration from the occurrence of the state in which the wireless tag identification information of the wireless tag 10b is not detected reaches the first duration time). (re-detection) (Yes in step S11), it is determined that the worker B has returned to the work place C, and the warning sound from the speaker 29b of the mobile terminal 20 owned by the worker A is stopped (step S12). The time count for determining the departure of member B is reset (step S13), and the process returns to step S2.

Note that the control unit 26 (wireless tag identification information detection means 60, work start judgment means 51, first judgment means 52, first warning means 55) of the mobile terminal 20 determines that the member B has temporarily left. before the time count for determining departure reaches the first duration time (before the duration time from the occurrence of the state in which the wireless tag identification information of the wireless tag 10b is not detected reaches the first duration time) (No in step S8) If the wireless tag identification information of the wireless tag 10b is not detected (redetected) (No in step S11), it is determined that the worker B has not returned to the work place C yet, and the process returns to step S7.

In addition, when Team Member A carrying the mobile terminal 20 leaves the work place C, the control unit 26 (wireless tag identification information detection means 60) of the portable terminal 20 detects the radio tag 10b carried by Team Member B and the work place C. The wireless tag identification information of the wireless tag 10c placed at C is no longer detected. After determining that the work has started, the control unit 26 (wireless tag identification information detection means 60, work start determination means 51, fourth determination means 58, second warning means 59) of the mobile terminal 20 detects the wireless tag owned by member A. While receiving the wireless tag identification information of the wireless tag 10a, if a situation occurs in which the wireless tag identification information of the wireless tag 10b owned by the worker B and the wireless tag 10c placed at the work place C is not detected (Yes in step S3), the wireless tag identification information of the wireless tag 10a is not detected. If the time count for A's decision to leave and the time count for team member A's temporary decision to leave are started, and the time count for team member A's temporary decision to leave reaches the second duration time, which is shorter than the first duration time (if the state is If the second duration is shorter than the first duration), it is determined that the member A has temporarily left (Yes in step S14), the time count for determining the temporary withdrawal of the member A is reset, and the member A is in possession of the item. A warning sound is emitted from the speaker 29b of the mobile terminal 20 to notify the user (step S15).

Note that, after determining that the work has started, the control unit 26 (wireless tag identification information detection means 60, work start determination means 51, fourth determination means 58) of the mobile terminal 20 detects the wireless tag 10a of the wireless tag possessed by member A. While receiving the identification information, a situation occurs in which the wireless tag identification information of the wireless tag 10b owned by team member B and the wireless tag 10c placed at work location C is not detected (Yes in step S3), and the decision to leave team member A is delayed. If the time count and the time count for team member A's temporary withdrawal decision are started, and the time count for team member A's temporary withdrawal decision has not reached the second duration time, which is shorter than the first duration time (the state does not last longer than the first duration time), If the second duration time is shorter than 1), it is not determined that member A has temporarily left (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 judgment means 56, the second information transmission means 57) of the mobile terminal 20 determines that the member A has temporarily left, and then determines the time period for the decision to leave the member A. When the count reaches the first duration time (when the duration time from the occurrence of the state in which the RFID tag identification information of the RFID tags 10b and 10c is not detected reaches the first duration time), 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. The server 30 connects the client terminal 40 and the mobile terminal 20 and starts a video call (step S17). Further, the control unit 26 (third determination means 56) of the mobile terminal 20 resets the time count for determining the withdrawal of member A at the same time as the start of the video call (step S18).

FIG. 10 is a diagram schematically showing a state in which the control unit 26 (third determining means 56) of the mobile terminal 20 determines that member A has left. As shown in FIG. 10, in a state where the control unit 26 (third judgment means 56) determines that worker A has left, only worker B is present at work location C, and worker A is at work location C. It is outside. In this state, a warning sound is being sounded from the speaker 29b of the mobile terminal 20 owned 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 surveillance center D determines whether there is a possibility of an abnormality occurring at the work place C based on the video call. If Supervisor E determines that there is a possibility that something unusual has occurred within Workplace C, he may instruct Worker A to return to Workplace C through a video call, depending on the situation, or send a message to a waiting staff member. Instruct the security guard to go directly to work location C and deal with the situation, or report to related organizations such as the police or fire department as necessary.

On the other hand, the control unit 26 (wireless tag identification information detection means 60, third judgment means 56, second warning means 59) of the mobile terminal 20, after determining that the member A has temporarily left, counts the time for the decision to leave the member A. (No in step S16), the wireless When the wireless tag identification information of the tag 10b and the wireless tag 10c is detected (redetected) (Yes in step S19), it is determined that the worker A has returned to the work place C, and the speaker 29b of the mobile terminal 20 belonging to the worker A is activated. The notification of the warning sound is stopped (step S20), the time count for determining the departure of member A is reset (step S21), and the process returns to step S2.

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

It is also conceivable that team member A intentionally turns off the power of the mobile terminal 20 that he/she owns when he/she leaves. As a countermeasure against this, for example, the control unit 26 (wireless tag identification information detection means 60, work start judgment means 51) of the mobile terminal 20 owned by Team Member A determines that the work has started and the time it judges that the work has ended. Once every 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 has been interrupted, it informs the client terminal 40 of an abnormality. It may be configured to display the occurrence. With such a configuration, even if the power of the mobile terminal 20 is intentionally cut off, the monitor E at the monitoring center D can notice it.

As described above, according to the present embodiment, complicated processing is not required, and by using radio waves from wireless tags, it is possible to grasp the number of workers at a work place using a mobile terminal. In addition, if you are working alone in a work area where working alone is prohibited, a supervisor can monitor the situation at a remote location such as a monitoring center by using the network communication of your mobile device. It can be grasped in real time. This makes it possible to prevent workers from working alone (prevents mistakes and risks) and prevents fraud by workers.

In this embodiment, there are two workers, A and B, but the number of workers is not limited to this, and three or more workers can also be used. In this case, after the control unit 26 determines that work is to begin upon detection of the wireless tag identification information of all the workers and the wireless tags 10 attached to the work place, the mobile terminal 20 determines that any one worker It is determined whether the mobile terminal 20 detects the wireless tag identification information of the wireless tag 10 while the mobile terminal 20 is left alone in the work place, and depending on the determination result, a warning sound is sounded or a video image with the client terminal 40 is activated. All you have to do is make a phone call or the like.

Furthermore, in this embodiment, the management server 30 extracts the wireless tag identification information and attachment location of a specific wireless tag 10 from the master data of the wireless tags 10 that it manages, based on the content of the work instruction. The configuration is such that the mobile terminal 20 stores this information in the storage unit 21, but the predetermined wireless tag identification information and the attachment location are stored in the storage unit 21 of the mobile terminal 20 in advance. may be configured.

Further, in the present embodiment, the leader A (first worker) carries the mobile terminal 20, but the invention is not limited to this, and the member B (second worker) also carries the mobile terminal 20. 20 may be held. In this case, the mobile terminal 20 of the worker B who remains in the work place C may issue a warning when it is determined that the worker A is temporarily leaving the work place. Further, the video call when it is determined that member A has left may be performed between member B's mobile terminal 20 and the client terminal 40 of monitoring center D. In this way, it becomes possible to more effectively prevent either team members A or B from working alone at work location C.

In addition, in this embodiment, the work place C is a fixed place such as a safe, but for example, it may be a luggage compartment of a vehicle where valuables are kept in the luggage compartment, such as a vehicle transporting valuables. The driver's cabin may also be targeted. Furthermore, by linking the mobile terminal with the travel control device of the vehicle concerned, and limiting the operation of the linked travel control device unless the mobile terminal determines that both members A and B are in the driver's cabin of the vehicle. , the vehicle may not be able to travel. In this way, it is possible that the vehicle with valuables stored in the luggage compartment is not only taken over and operated by a third party other than Team Members A and B, but also driven by either Team Member A or B alone. This can be prevented.

Further, in this embodiment, a wireless tag according to the BLE communication standard is used as an example of the transmitter, but the present invention is not limited to this. The transmitter may be any other communication means as long as it is a device that transmits identification information or the like. For example, non-contact radio (NFC: Near Field Communications), RFID, ultrasonic waves, light, etc. may be used.

Furthermore, in the present embodiment, the control unit 26 of the mobile terminal 20 is configured to determine whether the worker has left, etc., and to sound a warning sound or to start a video call with the client terminal 40 depending on the determination result. However, based on the detection information that the server 30 receives from the mobile terminal 20, the server 30 determines whether the worker holding the mobile terminal 20 and other accompanying workers leave the work place, and based on the determination result. In response, the server 30 sends an instruction to sound a warning sound to the mobile terminal 20, and the mobile terminal 20 is configured to sound a warning sound based on the instruction, or the server 30 sends an instruction to the mobile terminal 20 and the client terminal 40. and sends an instruction to the mobile terminal 20 to transmit 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 also do so.

Although the embodiment of the present invention has been described above, this embodiment is presented as an example, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.
