(Operation of Support System 200)
The operation of the support system 200 will be described.
FIG. 3 is a sequence diagram showing an example of the operation of the support system 200. In FIG. 3, it is assumed that the mobile terminal 6A is carried by a self-defense firefighter, and the mobile terminal 6B is carried by a person other than the self-defense firefighter. When the mobile terminal 6A and the mobile terminal 6B are not distinguished, the mobile terminal 6 will be described.

The mobile terminal 6 receives the beacon signal periodically transmitted from the position identification signal transmitter 5 by the position identification signal reception unit 601 at the normal cycle set by the cycle setting unit 604, and the mobile terminal position determination unit 602 detects the position. When the identification ID is confirmed (S01), the mobile terminal position information transmission unit 603 sets the mobile terminal ID determined by the mobile terminal position determination unit 602 and its own mobile terminal ID as the mobile terminal position information by the cycle setting unit 604. The information is transmitted to the support device 7 in the designated normal cycle (S02).
Here, the normal cycle is, for example, that the position identification signal receiving unit 601 performs a beacon signal receiving operation for 5 seconds and pauses for 5 seconds, which is repeated as one cycle, and the mobile terminal position determination unit 602 repeats the same position identification ID for 4 seconds. When the beacon signal with is superimposed is received, the position identification ID is determined as the received position identification ID. In addition, the mobile terminal position information transmission unit 603 transmits the mobile terminal position information to the support device 7 at intervals of 10 seconds.

In the support device 7, when the mobile terminal position information receiving unit 701 receives the mobile terminal position information, the mobile terminal position specifying unit 703 refers to the position identification signal transmitter information storage unit 702 and is included in the mobile position information. The installation position of the position identification signal transmitter 5 corresponding to the position identification ID is specified, and the current position of the mobile terminal 6 is specified (S03). Then, the current position information of the mobile terminals 6A and 6B of the mobile terminal position storage unit 704 is updated (S04).
The support system 200 repeats steps S01 to S04 as the normal operation, and updates the respective current positions of the mobile terminals 6 even in the normal time when no fire has occurred.

  When the fire receiver 2 receives the fire detection signal transmitted by the fire detector 1 that has detected the fire (S05), the address of the fire detector 1 that has detected the fire and the installed facility identification ID, building number, floor number A fire information signal including is transmitted to the support device 7 (S06). When the fire information signal is received by the fire information signal receiving unit 705 in the support device 7, the fire position specifying unit 707 refers to the self-fire alarm equipment information storage unit 704 based on the information included in the fire information signal. The location of the fire is specified (S07).

When the fire occurrence location is specified, the member selecting unit 709 selects a candidate from the member candidates stored in the member candidate information storage unit 708 for each role of the self-defense fire brigade (S08). When the member candidate is selected, the participation request transmission unit 710 transmits a request to participate in the activity of the self-defense fire brigade to the mobile terminal 6 carried by the selected member candidate (S09). In the example shown in FIG. 3, the participation request is transmitted to the mobile terminal 6A.
In the mobile terminal 6A, when the participation request is received by the participation request receiving unit 606, the content of the participation request is displayed on the user interface unit (S10). Start activities according to.

Further, when the fire occurrence location is specified, the cycle change selecting unit 711 selects the mobile terminal 6 carried by the self-defense fire brigade member in the facility where the fire is occurring, and selects the cycle to be changed (S11), The cycle changing signal is transmitted to the mobile terminal 6 selected by the cycle changing transmitting unit 712 as a cycle changing signal (S12). In the example shown in FIG. 3, the cycle change signal is transmitted to the mobile terminal 6A.
In the mobile terminal 6A to which the cycle changing signal is transmitted, when the cycle changing receiving section 606 receives the cycle changing signal, the cycle setting section 604 is changed from the normal cycle to the cycle included in the cycle changing signal. Here, the changed cycle is called an emergency cycle.

The mobile terminal 6A that has received the cycle change signal receives the beacon signal periodically transmitted from the position identification signal transmitter 5 by the position identification signal reception unit 601 in the emergency cycle set by the cycle setting unit 604, and When the terminal position determination unit 602 determines the position identification ID (S13), the mobile terminal position information transmission unit 603 sets the determined mobile terminal ID and its own mobile terminal ID as the mobile terminal position information by the cycle setting unit 604. It transmits to the support apparatus 7 in the designated emergency cycle (S14).
Here, the emergency cycle is shorter than the normal cycle, and as the emergency cycle, for example, the position identification signal receiving unit 601 continuously performs beacon signal reception operation, and the mobile terminal position determination unit 602 continues for 2 seconds. When the beacon signal on which the same position identification ID is superimposed is received, the position identification ID is determined as the received position identification ID. In addition, the mobile terminal position information transmission unit 602 transmits the mobile terminal position information to the support device 7 at intervals of 2 seconds.

For the mobile terminal 6B for which the cycle change signal has not been transmitted, reception of the beacon signal and determination of the position identification ID are continued in the same normal cycle as in step S01 (S15), and the mobile terminal position information is acquired in the same normal cycle as in step S02. Send.
In the support device 7, when the mobile terminal position information is received by the mobile terminal information receiving unit 701, the current position of the mobile terminal 6 is specified (S17) as in step S03, and the mobile position storage unit 704 stores the current position as in step S04. The current position of the mobile terminal 6 is updated (S18).

The route selection unit 713 selects an optimal route for each mobile terminal 6 based on a fire occurrence location, the current position of the mobile terminal 6, and whether the person carrying the mobile terminal 6 is a self-defense fire brigade member or another person. Yes (S19). The support information transmission unit 714 transmits optimum support information for each mobile terminal 6 (S20), and each mobile terminal 6 displays on the user interface unit based on the support information received by the support information reception unit 608 ( S21).
The support system 200 repeats the operations of steps S13 to S21 as an emergency operation, and in an emergency when a fire occurs, from the mobile terminal 6 carried by the self-defense firefighters in the facility at a shorter cycle than the normal operation, The current position of the mobile terminal 6 is updated.

  According to the operation of the support system 200 described above, the current position can be grasped by suppressing the battery consumption of the mobile terminal 6 in the normal time when no fire has occurred, and in the emergency when the fire occurs, the user is in the facility where the fire occurred. The current position of the mobile terminal 6 of the self-defense firefighter can be immediately grasped according to the movement of the self-defense firefighter.

(Modification)
