Further, the main control unit 58 functions as a route signal generation unit 581, a route signal acquisition unit 582, a communication control unit 583, a guidance control unit 584, and a power control unit 585.

  The route signal generation unit 581 has a function of generating the route signal of the exit signal, the fire signal, the smoke signal, the rescue request signal, and the disappearance signal in an identifiable manner. The path signal generation unit 581 generates a path signal including the unique ID 531 of the own device. That is, the route signal includes the unique ID 531 indicating the evacuation route guidance device 5 which is the transmission source.

  For example, when the outlet setting switch 57 (not shown) is set to ON, the path signal generation unit 581 is a transmission source of the outlet signal, and generates an outlet signal at a specific cycle (for example, one minute). Usually, the evacuation route guidance device 5 installed at the end functions as an exit device and serves as a source of exit signals.

  In addition, when the fire signal is received from the fire detection device 3 by the first transmission / reception unit 51 or the second transmission / reception unit 52, the route signal generation unit 581 becomes a transmission source of the fire signal and the fire signal including the unique ID Generate Further, when the smoke signal is received from the smoke detection device 4 by the first transmission / reception unit 51 or the second transmission / reception unit 52, the path signal generation unit 581 becomes a transmission source of the smoke signal and generates the smoke signal. Depending on the installation location of the fire detection device 3 or the smoke detection device 4, two evacuation route guidance devices 5 may be a transmission source.

  In addition, when the rescue request button is pressed, the route signal generation unit 581 becomes a transmission source of the rescue request signal and generates a rescue request signal. When the first transmission / reception unit 51 or the second transmission / reception unit 52 does not perform communication for a specific period of time, that is, the route signal generation unit 581 receives any of an exit signal, a fire signal, a smoke signal and a rescue request signal for a specific period of time. If the mum was not received, it would be the source of the lost signal, producing a lost signal.

  The path signal acquisition unit 582 has a function of acquiring the path signal received by the first transmission / reception unit 51, the path signal received by the second transmission / reception unit 52, and the path signal generated by the path signal generation unit 581.

  When the route signal is acquired by the route signal acquisition unit 582, the communication control unit 583 identifies the adjacent evacuation route guidance apparatus 5 as the transmission destination, and transmits the route signal to the evacuation route guidance apparatus 5 of the identified transmission destination. Have a function to For example, when the route signal acquired by the route signal acquisition unit 582 is the exit signal generated by the route signal generation unit 581, the communication control unit 583 identifies the adjacent evacuation route guidance apparatus 5 as the transmission destination. Further, when the route signal is acquired by the route signal acquisition unit 582 via the first transmission / reception unit 51, the communication control unit 583 identifies the evacuation route guidance device 5 connected to the second transmission / reception unit 52 as a transmission destination. When the route signal is acquired via the second transmission / reception unit 52, the evacuation route guidance apparatus 5 connected to the first transmission / reception unit 51 is specified as the transmission destination. Thus, the route signal is relayed between the evacuation route guidance devices 5.

  In the case where the route signal acquired by the route signal acquisition unit 582 is a fire signal or a smoke signal and is a route signal generated by the route signal generation unit 581 of the own device, the communication control unit 583 The exit signal acquired by the route signal acquisition unit 582 may be controlled not to be transmitted to the other evacuation route guidance apparatus 5 thereafter. This is to remove this fire source from the evacuation route.

  The guidance control unit 584 performs lighting control of the LED based on the type of the route signal acquired by the route signal acquisition unit 582 and the acquisition source. Thereby, the arrow corresponding to the lighted LED emits light, and the route information of the guide plate 54 in the left-right direction is notified.

  For example, when the route signal is an exit signal and the first transmission / reception unit 51 is an acquisition source, the LED 6a is turned on, and an arrow 5a indicating the left passage direction as “refuge” emits light. When the route signal is an exit signal and the second transmission / reception unit 52 is an acquisition source, the LED 6 f is turned on, and an arrow 5 f indicating the right passage direction as “refuge” emits light. When the route signal is an exit signal and the route signal generation unit 581 is an acquisition source, neither the LEDs 6a, 6f are turned on, nor any of the arrows 5a, 5f indicating the "refuge" in the left-right direction May be

  Further, when the route signal is a fire signal and the first transmission / reception unit 51 is an acquisition source, the LED 6b is turned on, and an arrow 5b indicating “fire present” in the left direction is emitted. When the route signal is a fire signal and the second transmission / reception unit 52 is an acquisition source, the LED 6g is turned on, and an arrow 5g indicating “fire present” in the right direction is emitted. When the route signal is a fire signal and the route signal generation unit 581 is an acquisition source, neither of the LEDs 6b and 6g is turned on, and neither of the arrows 5b and 5g indicating "fired" in the horizontal direction is emitted May be

  When the route signal is a smoke signal and the first transmission / reception unit 51 is an acquisition source, the LED 6c is turned on, and an arrow 5c indicating "with smoke" in the left direction is emitted. When the route signal is a smoke signal and the second transmission / reception unit 52 is an acquisition source, the LED 6h is turned on, and an arrow 5h indicating "with smoke" in the right direction is emitted. When the route signal is a smoke signal and the route signal generation unit 581 is an acquisition source, neither the LEDs 6c nor 6h are turned on, and neither the arrows 5c or 5h indicating "with smoke" in the horizontal direction are emitted May be

  Further, when the route signal is a rescue request signal and the first transmission / reception unit 51 is an acquisition source, the LED 6d is turned on, and an arrow 5d indicating "with relief delay" in the left direction is emitted. When the route signal is a rescue request signal and the second transmission / reception unit 52 is an acquisition source, the LED 6i is turned on, and an arrow 5i indicating "with relief delay" in the right direction is emitted. When the route signal is a rescue request signal and the route signal generation unit 581 is an acquisition source, neither of the LEDs 6d and 6i is turned on, and both of the arrows 5d and 5i indicating "with relief delay" in the horizontal direction emit light. You do not have to.

  When the path signal is a loss signal and the first transmission / reception unit 51 is an acquisition source, the LED 6e is turned on, and an arrow 5e indicating “signal loss” in the left direction emits light. When the path signal is a loss signal and the second transmission / reception unit 52 is an acquisition source, the LED 6 j is turned on, and an arrow 5 j indicating “signal loss” in the right direction is emitted. When the path signal is a disappearance signal and the path signal generation unit 581 is an acquisition source, neither of the LEDs 6e and 6j is turned on, and neither of the arrows 5e and 5j indicating "disappearance" in the horizontal direction emits light May be

  When the route signal is an exit signal, the guidance control unit 584 may turn off the lighted LEDs 6a and 6f when a specific time elapses after lighting the LEDs 6a and 6f. Then, next, when the exit signal is acquired with the first transmission / reception unit 51 or the second transmission / reception unit 52 as the acquisition source, the guidance control unit 584 may repeat turning on the LEDs 6a and 6f again for a specific period of time . At this time, the lighting time of the LEDs 6a and 6f may be set shorter than the generation interval of the exit signal by the path signal generation unit 581. According to this, each time the exit signal is received, the LEDs 6a and 6f can be blinked and displayed, and the light emission of the arrows 5a and 5f indicating the "refuge" can be made noticeable. The other LEDs 6b to 6e and the LEDs 6g to 6j may be kept on or may be blinked as the LEDs 6a and 6f.

  The power supply control unit controls the power supply circuit to supply power to each unit from an AC power supply or a rechargeable battery.

  Next, with reference to FIG. 8, the flow of the route signal transmission process of the evacuation route guidance apparatus 5 will be described.

  The path signal acquisition unit 582 determines whether the path signal is acquired from any of the first transmission / reception unit 51, the second transmission / reception unit 52, and the path signal generation unit 581 (s11).

  When the route signal is not acquired (s11: No), the route signal generation unit 581 determines whether the exit setting switch 57 is set to ON (s12). When the exit setting switch 57 is ON (s12: Yes), the evacuation path guidance device 5 functions as an exit device, generates an exit signal including the unique ID 531 (s13), and returns the process to s11.

  On the other hand, when the exit setting switch 57 is not ON (s12: No), the route signal generation unit 581 determines whether the first transmission / reception unit 51 or the second transmission / reception unit 52 receives a fire signal from the fire detection device 3 To do (s14). When the fire signal is received (s14: Yes), the route signal generation unit 581 generates a fire signal including the unique ID 531 (s15), and returns the process to s11.

  On the other hand, when the fire signal is not received (s14: No), the route signal generation unit 581 determines whether the smoke signal is received from the smoke detection device 4 by the first transmission / reception unit 51 or the second transmission / reception unit 52 To do (s16). If a smoke signal is received (s16: Yes), the path signal generation unit 581 generates a smoke signal including the unique ID 531 (s17), and returns the process to s11.

  On the other hand, when the smoke signal is not received (s16: No), the route signal generation unit 581 determines whether the rescue request button 541 is pressed (s18). When the rescue request button 541 is pressed (s18: Yes), the route signal generation unit 581 generates a rescue request signal including the unique ID 531 (s19), and returns the process to s11.

  On the other hand, when the rescue request button 541 is not pressed (s18: No), the route signal generation unit 581 causes the first transmission / reception unit 51 or the second transmission / reception unit 52 to output the exit signal, fire signal, smoke signal, rescue request signal. It is determined whether or not any path signal of the lost signal is received for a specific time (s20). If none of the path signals is received (s20: Yes), the path signal generation unit 581 generates a loss signal including the unique ID 531 (s21), and returns the process to s11. When one of the route signals is received (s20: No), the process returns to s11.

  When the route signal acquisition unit 582 acquires any of the route signal received by the first transmission / reception unit 51, the route signal received by the second transmission / reception unit 52, or the route signal generated by the route signal generation unit 581 (S11: Yes), it is determined whether the acquired path signal is generated by the path signal generation unit 581 of the own device (s22).

  In the case of the route signal generated by the own device (s22: Yes), the communication control unit 583 determines whether it is an exit signal or a loss signal (s23), and when it is an exit signal or a loss signal (s23: Yes) The exit signal or the disappearance signal is transmitted from the specific transmission / reception unit (s24), and the process is returned to s11. For example, when the evacuation route guidance device 5 with the unique ID 531: 001 shown in FIG. 1 functions as an exit device, the right side of the guide plate 54 is directed to the evacuation route guidance device 5 (unique ID 531: 002) on the adjacent passage 2 side. The exit signal is transmitted from the transceiver unit of In this case, the specific transmission / reception unit functions as a route signal transmission unit. Further, in the case of the lost signal, the transmission / reception unit on the opposite side to the transmission / reception unit on the side where the specific time path signal is not received is transmitted.

  On the other hand, if the route signal generated by the own device is not the exit signal (s23: No), the communication control unit 583 determines whether it is a fire signal or a smoke signal (s25). When it is a fire signal or a smoke signal (s25: Yes), the communication control unit 583 sets the exit signal stop flag to ON (s26), and the path from both the first transmission / reception unit 51 and the second transmission / reception unit 52 A signal is transmitted (s27), and the process returns to s11. When it is neither a fire signal nor a smoke signal (s25: No), the process of setting the exit signal stop flag to ON is not executed, and the route signal from both the first transmission / reception unit 51 and the second transmission / reception unit 52 Is transmitted (s27), and the process returns to s11. As described above, when the own device is a transmission source of a fire signal or a smoke signal, the communication control unit 583 sets the outlet signal stop flag to ON to stop the transmission of the outlet signal in the own device, and the own device Control to exclude from the evacuation route.

  On the other hand, when the acquired route signal is not generated by the own device (s22: No), that is, when the own device is installed in the middle part of the evacuation route, the first transmission / reception unit 51 Alternatively, the second transmission / reception unit 52 receives a route signal from the adjacent evacuation route guidance device 5 and records the reception history 532 (s28). Subsequently, the lighting control unit corresponds to the type of the route signal among the LEDs disposed on the side of the transmitting / receiving unit (receiving side) that has received the route signal among the first transmitting / receiving unit 51 and the second transmitting / receiving unit 52 Turn on the LED (s29).

  Thus, for example, when the exit signal is received by the first transmission / reception unit 51, the LED 6a is turned on, and the arrow 5a indicating the left direction is emitted as the "refuge". Further, when a fire signal is received by the second transmission / reception unit 52, the LED 6g is turned on, and an arrow 5g indicating the right direction is emitted as "fired". The lighting control unit may control to turn off the LED 6a or the LED 6f after a specific time has elapsed when the LED 6a or the LED 6f is turned on based on the exit signal. The LEDs 6b to 6e and the LEDs 6g to 6j may not be turned off after being turned on.

  Subsequently, the communication control unit 583 determines the transfer of the route signal. The communication control unit 583 determines whether the route signal to be transferred is an exit signal (s30). If it is not the exit signal (s30: No), the communication control unit 583 transfers the route signal from the transmission / reception unit on the opposite side to the transmission / reception unit that is the reception source (s31), and returns the process to s11. Thus, for example, when the route signal to be transferred is received by the first transmission / reception unit 51, it is transferred from the second transmission / reception unit 52, and when it is received by the second transmission / reception unit 52, it is transferred from the first transmission / reception unit 51. Ru.

  On the other hand, when the route signal to be transferred is the exit signal (s30: Yes), the communication control unit 583 determines whether the exit signal stop flag is set to ON (s32). If the exit signal stop flag is not ON (s32: No), the process proceeds to s31, and the exit signal is transferred from the transmission / reception unit on the opposite side to the transmission / reception unit that is the reception source. On the other hand, when the exit signal stop flag is ON (s32: Yes), the communication control unit 583 stops the transfer of the exit signal received from the adjacent evacuation route guiding device 5 (s33), and returns the process to s11.

  For example, FIG. 7 is a diagram showing the reception history of the unique ID: 006. The evacuation route guidance device 5 with the unique ID: 006 received the exit signal originating from the unique ID: 001 and the unique ID: 053, but received the smoke signal originating from the unique ID: 051 After that, the exit signal from unique ID: 053 has not been received. This is because the evacuation route guidance device 5 with the unique ID: 051 is the source of the smoke signal, and the transfer of the exit signal is stopped. Therefore, the exit signal originating from the unique ID: 051 with the unique ID: 053 is not transferred, and the guide plate 54 of the unique ID: 006 does not emit the arrow 5f indicating the unique ID: 053 side, and the unique ID: Only the arrow 5a indicating the 001 side emits light.

  In addition, by installing an application related to the evacuation route guidance apparatus 5 in a mobile terminal (external terminal) such as a smartphone or a tablet terminal, the mobile terminal can receive the reception history 532 from the evacuation route guidance apparatus 5 via the application You may When the mobile terminal receives the reception history 532, it displays, for example, a map showing the evacuation route of the passage 2 based on the application, and the location of the evacuation route guidance device 5 where a fire or smoke is generated, or a rescue request The location of the evacuation route guidance device 5 where the button 541 is pressed or the location of the evacuation route guidance device 5 installed at the exit may be confirmed. Moreover, according to this, the fire brigade etc. acquire the reception history 532 from the evacuation route guidance apparatus 5 installed at the exit through the portable terminal, and the location etc. of the evacuation route guidance apparatus 5 where the rescue requester is present Can be grasped.

  Thus, the evacuation route guidance system 1 includes a plurality of evacuation route guidance devices 5 installed at intervals to the exit in the passage 2 which can travel in both directions, and the evacuation route guidance device 5 installed at the end is A route signal generation unit 581 that generates an exit signal at a specific cycle as a route signal, and a route signal transmission unit that transmits an exit signal to the adjacent evacuation route guidance device 5, and the evacuation route guidance device installed in the middle 5, a first transmitting / receiving unit 51 communicating with one adjacent evacuation route guiding device 5, a second transmitting / receiving unit 52 communicating with the other adjacent evacuation route guiding device 5, and one evacuation by the first transmitting / receiving unit 51 The exit signal received from the route guidance device 5 is transferred to the other evacuation route guidance device 5 via the second transmission / reception unit 52, and the exit signal received from the other evacuation route guidance device 5 by the second transmission / reception unit 52 is Second Based on the communication control unit 583 transferred to one evacuation route guidance apparatus 5 via the transmission / reception unit 51 and the passage direction in which one evacuation route guidance apparatus 5 is installed based on the exit signal received by the first transmission / reception unit 51 A guidance control unit that reports the first evacuation direction, and reports the second evacuation direction, which is the passage direction in which the other evacuation route guidance device 5 is installed, based on the exit signal received by the second transmission / reception unit 52 And 584. Thus, each evacuation route guiding device 5 transfers the route signal received from one adjacent evacuation route guiding device 5 to the other adjacent evacuation route guiding device 5 and notifies the evacuation direction based on the received route signal. You can guide the evacuation route with a simple configuration. Therefore, it is possible to guide the evacuation route with low power consumption, which is effective at the time of disaster.

  The fire information generation unit 34 and the smoke information generation unit 44 may respectively generate a fire signal and a smoke signal described later including the unique ID. In this case, the fire detection device 3 is a transmission source of the fire signal, and the smoke detection device 4 is a transmission source of the smoke signal.

  Further, the notification form by the guidance control unit 584 is not limited to the case of notifying the corresponding arrows 5a to 5j indicating the first evacuation direction or the second evacuation direction by lighting control on the LEDs 6a to 6j, for example, via an actuator or the like. Notification may be made by causing the arrows 5a to 5j to physically appear from the guide plate 54.

  Further, the communication control unit 583 sets the exit signal stop flag to ON when the fire signal or smoke signal is generated by the route signal generation unit 581, and controls so as not to transfer when the exit signal is received thereafter. Is not limited to this. For example, after the fire signal or smoke signal is generated by the route signal generation unit 581, the communication control unit 583 may transfer the exit signal to the adjacent evacuation route guidance apparatus 5. In this case, when the exit signal is received after the fire signal or smoke signal is received by the first transmission / reception unit 51, the guidance control unit 584 does not turn on the LED 6a and does not notify the arrow 5a indicating "refuge". If the exit signal is received after the fire signal or smoke signal is received by the second transmission / reception unit 52, the LED 6f is not turned on, and the arrow 5f indicating the “refuge” is not notified. It is also good.

  The present invention is not limited to the above-described embodiment, and it goes without saying that various changes can be made without departing from the spirit of the present invention.
