例えば、経路信号生成部581は、不図示の出口設定スイッチ57がONに設定されている場合、出口信号の発信源となり、特定周期(例えば1分)で出口信号を生成する。通常、端部に設置された避難経路案内装置5が出口装置として機能し、出口信号の発信源となる。   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.

また、経路信号生成部581は、第1送受信部51又は第2送受信部52により火災検知装置3から火災信号が受信された場合に、火災信号の発信源となり、固有IDを含めた火災信号を生成する。また、経路信号生成部581は、第1送受信部51又は第2送受信部52により煙検知装置4から煙信号が受信された場合に、煙信号の発信源となり、煙信号を生成する。火災検知装置3又は煙検知装置4の設置場所によっては、2台の避難経路案内装置5が発信源となってもよい。   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.

また、経路信号生成部581は、救助要請ボタンが押下された場合に、救助要請信号の発信源となり、救助要請信号を生成する。そして、経路信号生成部581は、第1送受信部51又は第2送受信部52により特定時間通信がなかった場合、つまり、特定時間の間、出口信号、火災信号、煙信号及び救助要請信号のいずれもが受信されなかった場合、消失信号の発信源となり、消失信号を生成する。   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.

経路信号取得部582は、第1送受信部51により受信された経路信号、第2送受信部52により受信された経路信号、及び経路信号生成部581により生成された経路信号を取得する機能を有する。また、経路信号取得部582は、第1送受信部51又は第2送受信部52を介して経路信号を取得した場合に、記憶部53に経路信号の受信履歴532を蓄積する。   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. In addition, when the route signal acquisition unit 582 acquires a route signal via the first transmission / reception unit 51 or the second transmission / reception unit 52, the route signal acquisition unit 582 stores the reception history 532 of the route signal in the storage unit 53.

図7は、受信履歴532の蓄積例である。受信履歴532は、経路信号の生成元を示す固有ID531、経路信号種別、受信日時とを含んでいる。受信履歴532は、直近の特定期間を残すように更新されてもよい。   FIG. 7 is a storage example of the reception history 532. The reception history 532 includes a unique ID 531 indicating a generation source of the route signal, a route signal type, and a reception date and time. The reception history 532 may be updated to leave the latest specific period.

通信制御部583は、経路信号取得部582により経路信号が取得されると、送信先とする隣接の避難経路案内装置5を特定し、特定した送信先の避難経路案内装置5に経路信号を送信する機能を有する。例えば、通信制御部583は、経路信号取得部582により取得された経路信号が経路信号生成部581により生成された出口信号である場合、隣接する避難経路案内装置5を送信先として特定する。また、通信制御部583は、経路信号取得部582により第1送受信部51を介して経路信号が取得された場合、第2送受信部52に接続された避難経路案内装置5を送信先として特定し、第2送受信部52を介して経路信号が取得された場合、第1送受信部51に接続された避難経路案内装置5を送信先として特定する。これにより、経路信号は避難経路案内装置5間をリレー式に伝搬される。   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.

なお、通信制御部583は、経路信号取得部582により取得された経路信号が火災信号又は煙信号であって、自装置の経路信号生成部581によって生成された経路信号である場合には、それ以降に経路信号取得部582により取得された出口信号を他の避難経路案内装置5に送信しないように制御してもよい。火災元となっているこの場所を避難経路から外すためである。   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.

案内制御部584は、経路信号取得部582により取得された経路信号の種別と取得元に基づいて、LEDの点灯制御を行う。これにより、点灯したLEDに対応する矢印が発光して、案内板54の左右方向の経路情報が報知される。   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.

例えば、経路信号が出口信号であり、第1送受信部51が取得元である場合、LED6aが点灯し、左の通路方向を「避難路」として示す矢印5aが発光する。経路信号が出口信号であり、第2送受信部52が取得元である場合、LED6fが点灯し、右の通路方向を「避難路」として示す矢印5fが発光する。経路信号が出口信号であり、経路信号生成部581が取得元である場合は、LED6a、6fのいずれも点灯せず、左右方向の「避難路」を示す矢印5a、5fのいずれも発光しなくてもよい。   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

また、経路信号が火災信号であり、第1送受信部51が取得元である場合、LED6bが点灯し、左方向の「火災あり」を示す矢印5bが発光する。経路信号が火災信号であり、第2送受信部52が取得元である場合、LED6gが点灯し、右方向の「火災あり」を示す矢印5gが発光する。経路信号が火災信号であり、経路信号生成部581が取得元である場合は、LED6b、6gのいずれも点灯せず、左右方向の「火災あり」を示す矢印5b、5gのいずれも発光しなくてもよい。   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

また、経路信号が煙信号であり、第1送受信部51が取得元である場合、LED6cが点灯し、左方向の「煙あり」を示す矢印5cが発光する。経路信号が煙信号であり、第2送受信部52が取得元である場合、LED6hが点灯し、右方向の「煙あり」を示す矢印5hが発光する。経路信号が煙信号であり、経路信号生成部581が取得元である場合は、LED6c、6hのいずれも点灯せず、左右方向の「煙あり」を示す矢印5c、5hのいずれも発光しなくてもよい。   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

また、経路信号が救助要請信号であり、第1送受信部51が取得元である場合、LED6dが点灯し、左方向の「逃げ遅れあり」を示す矢印5dが発光する。経路信号が救助要請信号であり、第2送受信部52が取得元である場合、LED6iが点灯し、右方向の「逃げ遅れあり」を示す矢印5iが発光する。経路信号が救助要請信号であり、経路信号生成部581が取得元である場合は、LED6d、6iのいずれも点灯せず、左右方向の「逃げ遅れあり」を示す矢印5d、5iのいずれも発光しなくてもよい。   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.

また、経路信号が消失信号であり、第1送受信部51が取得元である場合、LED6eが点灯し、左方向の「信号消失」を示す矢印5eが発光する。経路信号が消失信号であり、第2送受信部52が取得元である場合、LED6jが点灯し、右方向の「信号消失」を示す矢印5jが発光する。経路信号が消失信号であり、経路信号生成部581が取得元である場合は、LED6e、6jのいずれも点灯せず、左右方向の「信号消失」を示す矢印5e、5jのいずれも発光しなくてもよい。   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

経路信号が出口信号である場合、案内制御部584は、LED6a、6fを点灯後に特定時間経過すると、点灯させたLED6a、6fを消灯させてもよい。そして、次に、第1送受信部51又は第2送受信部52を取得元として出口信号が取得された場合に、案内制御部584は、再びLED6a、6fを特定時間点灯させることを繰り返しても良い。このとき、LED6a、6fの点灯時間は、経路信号生成部581による出口信号の生成間隔より短く設定されてもよい。これによれば、出口信号が受信される毎にLED6a、6fを点滅表示させることができ、「避難路」を示す矢印5a、5fの発光を目立たせることができる。なお、他のLED6b〜6e及びLED6g〜6jは、点灯し続けたままでもよいし、LED6a、6fのように点滅表示されてもよい。   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.

電源制御部は、電源回路を制御して交流電源又は充電池から各部に電源を供給する。   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.

次に、図8を参照して、避難経路案内装置5の経路信号伝達処理の流れを説明する。   Next, with reference to FIG. 8, the flow of the route signal transmission process of the evacuation route guidance apparatus 5 will be described.

経路信号取得部582は、第1送受信部51、第2送受信部52及び経路信号生成部581のいずれかから経路信号を取得したか否かを判断する(s11)。   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).

経路信号が取得されていない場合(s11:No)、経路信号生成部581は、出口設定スイッチ57がONに設定されているか否かを判断する(s12)。出口設定スイッチ57がONの場合(s12:Yes)、避難経路案内装置5は出口装置として機能し、固有ID531を含めて出口信号を生成し(s13)、s11に処理を戻す。   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.

一方、出口設定スイッチ57がONでない場合(s12:No)、経路信号生成部581は、第1送受信部51又は第2送受信部52により火災検知装置3から火災信号を受信したか否かを判断する(s14)。火災信号を受信した場合(s14:Yes)、経路信号生成部581は、固有ID531を含めて火災信号を生成し(s15)、s11に処理を戻す。   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.

一方、火災信号を受信していない場合(s14:No)、経路信号生成部581は、第1送受信部51又は第2送受信部52により煙検知装置4から煙信号を受信したか否かを判断する(s16)。煙信号を受信した場合(s16:Yes)、経路信号生成部581は、固有ID531を含めて煙信号を生成し(s17)、s11に処理を戻す。   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.

一方、煙信号を受信していない場合(s16:No)、経路信号生成部581は、救助要請ボタン541が押下されたか否かを判断する(s18)。救助要請ボタン541が押下された場合(s18:Yes)、経路信号生成部581は、固有ID531を含めて救助要請信号を生成し(s19)、s11に処理を戻す。   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.

一方、救助要請ボタン541が押下されていない場合(s18:No)、経路信号生成部581は、第1送受信部51又は第2送受信部52により、出口信号、火災信号、煙信号、救助要請信号、消失信号のいずれの経路信号も特定時間受信なしか否かを判断する(s20)。いずれの経路信号も受信なしの場合(s20:Yes)、経路信号生成部581は、固有ID531を含めて消失信号を生成し(s21)、s11に処理を戻す。いずれかの経路信号を受信した場合は(s20:No)、s11に処理が戻る。   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.

経路信号取得部582は、第1送受信部51により受信された経路信号、第2送受信部52により受信された経路信号、又は経路信号生成部581により生成された経路信号のいずれかを取得した場合(s11:Yes)、取得した経路信号が自装置の経路信号生成部581により生成されたものか否かを判断する(s22)。   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).

自装置で生成された経路信号の場合(s22:Yes)、通信制御部583は、出口信号又は消失信号か否かを判断し(s23)、出口信号又は消失信号である場合には(s23:Yes)、特定の送受信部から出口信号又は消失信号を送信し(s24)、s11に処理を戻す。例えば、図1に示す固有ID531:001の避難経路案内装置5が出口装置として機能する場合、隣接する通路2側の避難経路案内装置5(固有ID531:002)に向けて、案内板54の右側の送受信部から出口信号が送信される。この場合、特定の送受信部は、経路信号送信部として機能する。また、消失信号の場合は、特定時間経路信号が受信されなかった側の送受信部側と逆側の送受信部から送信される。   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.

一方、自装置で生成された経路信号が出口信号でなかった場合(s23:No)、通信制御部583は、火災信号又は煙信号であるか否かを判断する(s25)。火災信号又は煙信号であった場合(s25:Yes)、通信制御部583は、出口信号停止フラグをONに設定して(s26)、第1送受信部51及び第2送受信部52の両方から経路信号を送信し(s27)、s11に処理を戻す。火災信号及び煙信号のいずれでもなかった場合は(s25:No)、出口信号停止フラグをONに設定する処理が実行されずに、第1送受信部51及び第2送受信部52の両方から経路信号が送信され(s27)、s11に処理が戻る。このように、自装置が火災信号又は煙信号の発信源となる場合、通信制御部583は、出口信号停止フラグをONに設定することで、自装置における出口信号の伝達を停止し、自装置を避難経路から除外するように制御する。   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.

一方、経路信号取得部582は、取得した経路信号が自装置で生成したものでない場合(s22:No)、すなわち、自装置が避難経路の中間部に設置されている場合、第1送受信部51又は第2送受信部52により、隣接する避難経路案内装置5から経路信号を受信して、受信履歴532を記録する(s28)。つづいて、点灯制御部は、第1送受信部51及び第2送受信部52の内、経路信号を受信した送受信部側(受信元側)に配置されたLEDの内、経路信号の種別に対応するLEDを点灯させる(s29)。   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).

これにより、例えば第1送受信部51により出口信号が受信された場合、LED6aが点灯し、「避難路」として左方向を示す矢印5aが発光する。また、第2送受信部52により火災信号が受信された場合は、LED6gが点灯し、「火災あり」として右方向を示す矢印5gが発光する。なお、点灯制御部は、出口信号に基づいてLED6a又はLED6fを点灯させた場合、特定時間経過後にLED6a又はLED6fを消灯させるように制御してもよい。LED6b〜6e、及びLED6g〜6jについては、点灯後に消灯制御しなくてもよい。   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.

つづいて、通信制御部583は、経路信号の転送について判断する。通信制御部583は、転送対象の経路信号が出口信号であるか否かを判断する(s30)。出口信号でない場合(s30:No)、通信制御部583は、経路信号の受信元の送受信部と逆側の送受信部から転送し(s31)、s11に処理を戻す。これにより、例えば、転送対象の経路信号が第1送受信部51により受信された場合、第2送受信部52から転送され、第2送受信部52により受信された場合、第1送受信部51から転送される。   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.

一方、転送対象の経路信号が出口信号である場合(s30:Yes)、通信制御部583は、出口信号停止フラグがONに設定されているか否かを判断する(s32)。出口信号停止フラグがONでない場合(s32:No)、s31に処理が進み、出口信号が受信元となった送受信部と逆側の送受信部から転送される。一方、出口信号停止フラグがONである場合(s32:Yes)、通信制御部583は、隣接する避難経路案内装置5から受信した出口信号の転送を停止し(s33)、s11に処理を戻す。   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.

例えば、図7は、固有ID:006の受信履歴を示した図である。固有ID:006の避難経路案内装置5は、固有ID:001及び固有ID:053を発信源とする出口信号をそれぞれ受信していたが、固有ID:051を発信源とする煙信号を受信して以降、固有ID:053からの出口信号を受信していない。これは、固有ID:051の避難経路案内装置5が煙信号の発信源となったことにより、出口信号の転送を停止したからである。そのため、固有ID:051から固有ID:053を発信源とする出口信号が転送されず、固有ID:006の案内板54は、固有ID:053側を示す矢印5fが発光せず、固有ID:001側を示す矢印5aのみが発光する。   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.

なお、スマートフォンやタブレット端末等の携帯端末(外部端末)に避難経路案内装置5に関するアプリケーションをインストールしておくことで、携帯端末がアプリケーションを介して避難経路案内装置5から受信履歴532を受信できるようにしてもよい。携帯端末は、受信履歴532を受信すると、アプリケーションに基づいて、例えば、通路2の避難経路を示す地図を表示して、火災や煙が発生している避難経路案内装置5の場所や、救助要請ボタン541が押された避難経路案内装置5の場所や、出口に設置された避難経路案内装置5の場所を確認できるようにしてもよい。また、これによれば、消防隊員等が携帯端末を介して出口に設置された避難経路案内装置5から受信履歴532を取得して、救助要請者がいる避難経路案内装置5の場所等を的確に把握することができる。   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.

このように、避難経路案内システム1は、両方向に行き来可能な通路2に出口まで間隔をおいて設置された複数の避難経路案内装置5を備え、端部に設置された避難経路案内装置5は、経路信号として特定周期で出口信号を生成する経路信号生成部581と、隣接する避難経路案内装置5に出口信号を送信する経路信号送信部とを備え、中間部に設置された避難経路案内装置5は、隣接する一方の避難経路案内装置5と通信する第1送受信部51と、隣接する他方の避難経路案内装置5と通信する第2送受信部52と、第1送受信部51により一方の避難経路案内装置5から受信した出口信号を、第2送受信部52を介して他方の避難経路案内装置5に転送し、第2送受信部52により他方の避難経路案内装置5から受信した出口信号を、第1送受信部51を介して一方の避難経路案内装置5に転送する通信制御部583と、第1送受信部51により受信された出口信号に基づいて、一方の避難経路案内装置5が設置された通路方向である第1避難方向を報知し、第2送受信部52により受信された出口信号に基づいて、他方の避難経路案内装置5が設置された通路方向である第2避難方向を報知する案内制御部584とを備えたことを特徴とする。これにより、各避難経路案内装置5は、隣接する一方の避難経路案内装置5から受信した経路信号を隣接する他方の避難経路案内装置5に転送し、受信した経路信号に基づいて避難方向を報知するという簡易な構成で避難経路を案内することができる。そのため、低消費電力で避難経路を案内することができ、災害時に効果的である。   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.

なお、火災情報生成部34、煙情報生成部44がそれぞれ固有IDを含めて後述の火災信号、煙信号を生成してもよい。この場合、火災検知装置3が火災信号の発信源となり、煙検知装置4が煙信号の発信源となる。   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.

また、案内制御部584による報知形態は、LED6a〜6jに対する点灯制御により第1避難方向又は第2避難方向を示す該当の矢印5a〜5jを報知する場合に限らず、例えば、アクチュエーター等を介して物理的に矢印5a〜5jを案内板54から出現させることで報知してもよい。   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.

また、通信制御部583は、経路信号生成部581により火災信号又は煙信号が生成された場合に出口信号停止フラグをONにして、それ以降に出口信号を受信した場合に転送しないように制御したがこれに限らない。例えば、経路信号生成部581により火災信号又は煙信号が生成された以降も通信制御部583が出口信号を隣接の避難経路案内装置5に転送するようにしてもよい。この場合、案内制御部584は、第1送受信部51により火災信号又は煙信号を受信後に出口信号が受信された場合に、LED6aを点灯せずに「避難路」を示す矢印5aを報知しないように制御して、第2送受信部52により火災信号又は煙信号を受信後に出口信号が受信された場合に、LED6fを点灯せずに「避難路」を示す矢印5fを報知しないように制御してもよい。   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.
