Description

本発明は、トンネル内に設置した火災検出器及び他の端末機器を防災監視盤に接続してトンネル内の異常を監視するトンネル防災システムに関する。   The present invention relates to a tunnel disaster prevention system that monitors a malfunction in a tunnel by connecting a fire detector and other terminal equipment installed in the tunnel to a disaster prevention monitoring panel.

従来、自動車専用道路等のトンネルには、トンネル内で発生する火災事故から人身及び車両を守るため、非常用施設が設置されている。   Conventionally, emergency facilities have been installed in tunnels for exclusive use of automobiles and the like in order to protect people and vehicles from fire accidents that occur in the tunnel.

このような非常用施設としては、火災の監視と通報のため火災検出器、手動通報装置、非常電話が設けられ、また火災の消火や延焼防止のために消火栓装置が設けられ、更にトンネル躯体を火災から防護するために水噴霧ヘッドから消火用水を散水させる水噴霧などが設置され、これらの非常用施設の端末機器を監視制御する防災受信盤を設けることで、トンネル防災システムを構築している。   Such emergency facilities are equipped with fire detectors, manual notification devices, emergency telephones for fire monitoring and reporting, fire hydrant devices for fire extinguishing and fire spread prevention, and tunnel enclosures. In order to protect against fire, a water spray that sprays water for fire extinguishing from the water spray head is installed, and a disaster prevention system is built by monitoring and controlling the terminal equipment of these emergency facilities. .

防災受信盤と端末機器で構成するトンネル防災システムは、Ｒ型伝送方式とＰ型直送方式に大別される。Ｒ型伝送方式は、伝送回線にアドレスを設定した火災検出器等の端末機器を接続し、伝送制御により端末機器単位に検知と制御を行う個別管理を可能とする、Ｐ型直送方式は、端末機器の種別に応じて所定の区画単位に分け、区画単位に引き出した信号回線に同一区画に入る複数の端末機器を接続し、信号回線単位に検知と制御を行う。   A tunnel disaster prevention system composed of a disaster prevention receiving board and terminal equipment is roughly divided into an R type transmission system and a P type direct transmission system. The R-type transmission method connects a terminal device such as a fire detector whose address is set to the transmission line, and enables individual management to perform detection and control for each terminal device by transmission control. A plurality of terminal devices that enter the same section are connected to a signal line drawn out for each partition according to the type of device, and detection and control are performed for each signal line.

トンネル防災システムとしては、Ｒ型伝送方式とＰ型直送方式のメリットとデメリット、トンネル長や車両の交通量等を考慮して、Ｒ型伝送方式又はＰ型直送方式のトンネル防災システムを構築するようにしている。   As a tunnel disaster prevention system, considering the merits and demerits of the R type transmission method and the P type direct delivery method, the tunnel length, the traffic volume of the vehicle, etc., the tunnel disaster prevention system of the R type transmission method or the P type direct delivery method will be constructed. I have to.

特開２００２−２４６９６２号公報Japanese Patent Laid-Open No. 2002-246962 特開平１１−１２８３８１号公報JP-A-11-128381

ところで、近年のトンネル防災システムにあっては、防災受信盤で火災検出器の１台目の火災発報を判別した場合は、予備警報として扱うことで、特定の設備を連動制御して注意を喚起し、火災検出器の２台目の火災発報を検出した場合、火災として扱い、全設備を連動制御することが要求されている。   By the way, in the recent tunnel disaster prevention system, when the first fire alarm of the fire detector is discriminated by the disaster prevention reception board, it is handled as a preliminary alarm, and the specific equipment is linked and controlled. If a second fire alarm is detected by the fire detector, it is required to treat it as a fire and control all the equipment in conjunction.

しかしながら、火災検出器の内の２台目の火災発報を検出した場合に火災として扱うようにした場合には、トンネル長手方向に２５メートル間隔又は５０メートル間隔で多数の火災検出器を設置していることから、別々の設置場所で火災以外の要因により火災検出器が誤発報する可能性があり、非火災報であるにも関わらず火災として扱ってしまう問題がある。   However, if a fire alarm is detected when the second fire alarm is detected, a number of fire detectors are installed at 25 or 50 meter intervals in the tunnel longitudinal direction. Therefore, there is a possibility that the fire detector may falsely report due to factors other than the fire at different installation locations, and there is a problem that it is handled as a fire despite being a non-fire report.

また、交通事故等によりトンネル内で火災が発生した場合、火災検出器が火災発報する以外に、関係者が消火栓装置を使用して消火を行ったり、消火栓装置に設けている発信機を操作して通報する場合があり、これらの火災関連操作を火災検出器の火災発報と合わせて判断すれば、より確実に火災を判断して非火災報を抑制することが可能となる。   In addition, when a fire occurs in a tunnel due to a traffic accident, the fire detector uses a fire hydrant device to extinguish the fire, or operates a transmitter installed in the fire hydrant device. If these fire-related operations are judged together with the fire alarm of the fire detector, it is possible to judge the fire more reliably and suppress the non-fire report.

本発明は、火災検出器による火災発報に基づく非火災報を抑制して、火災を確実に判断することを可能とするトンネル防災システムを提供することを目的とする。   An object of the present invention is to provide a tunnel disaster prevention system capable of suppressing a non-fire report based on a fire report by a fire detector and reliably determining a fire.

（Ｒ型トンネル防災システム１の効果）
本発明は、防災受信盤に、トンネル内に設置した複数の火災検出器を接続して監視するトンネル防災システムに於いて、防災受信盤に、トンネル内に引き出した伝送回線に複数の火災検出器を接続し、火災検出器との間で所定の伝送制御に基づき、火災検出器による火災発報を個別に検出するＲ型伝送部と、Ｒ型伝送部による１台目の火災感知器の火災発報の検出を判別した場合に予備警報制御を行うと共に、火災発報を検出した火災検出器の両側に連続して隣接する所定数の火災検出器を火災判別候補に設定し、Ｒ型伝送部による火災判別候補に入る２台目の火災検出器の火災発報の検出を判別した場合に、火災警報制御を行う制御部と、を設けるようにしたため、火災の進展状況に合わせて段階的に警報することで、火災の可能性を報知する予備警報の段階では管理担当者及びトンネル通行中の車両運転者等に注意を喚起して続いて予測される火災警報に対する心構えを促し、火災を判別して火災警報が出された場合に必要な対処を迅速且つ適切に可能とし、不要な混乱を未然に防止可能とする。 (Effect of R type tunnel disaster prevention system 1)
The present invention relates to a disaster prevention system for monitoring and connecting a plurality of fire detectors installed in a tunnel to a disaster prevention receiver, and a plurality of fire detectors on a transmission line drawn into the tunnel to the disaster prevention receiver. Connected to the fire detector, and based on the prescribed transmission control, the R-type transmission unit that individually detects fire alarms by the fire detector, and the fire of the first fire detector by the R-type transmission unit Preliminary alarm control is performed when the detection of an alarm is determined, and a predetermined number of fire detectors adjacent to both sides of the fire detector that detects the fire alarm are set as fire determination candidates, and R-type transmission is performed. A control unit that performs fire alarm control when the detection of a fire alarm of the second fire detector that enters the fire detection candidate by the unit is determined is provided. Alerts you to the possibility of a fire At the preliminary warning stage, it is necessary to alert the manager in charge and the vehicle driver in the tunnel, etc., to be prepared for the fire alarm that is predicted, and to detect a fire and to issue a fire alarm. It is possible to quickly and appropriately deal with such a situation and to prevent unnecessary confusion.

また、２台の火災検出器による火災発報があっても、火災発報を検出した火災検出器の両側に連続して隣接する１又は複数の火災検出器となる火災判別候補に入らない離れた場所の火災検出器の火災発報の検出であれば、火災以外の原因による可能性か高いことから火災警報を行わずに予備警報を維持して非火災報を未然に防止可能とする。   In addition, even if there is a fire report from two fire detectors, the fire detection candidate that will be one or more fire detectors adjacent to both sides of the fire detector that has detected the fire report is not included. If a fire alarm is detected by a fire detector at a new location, the possibility of a cause other than a fire is high, so a preliminary alarm is maintained without a fire alarm, so that a non-fire alarm can be prevented.

（Ｒ型トンネル防災システム２の効果）
また、本発明は、防災受信盤に、トンネル内に設置した複数の火災検出器及び複数の発信機を接続して監視するトンネル防災システムに於いて、防災受信盤に、トンネル内に引き出した伝送回線に複数の火災検出器及び複数の発信機を接続し、火災検出器及び発信機との間で所定の伝送制御に基づき、火災検出器による火災発報及び発信機による火災通報を個別に検出するＲ型伝送部と、Ｒ型伝送部による１台目の火災感知器の火災発報の検出またはＲ型伝送部による発信機の火災通報の検出を判別した場合に予備警報制御を行うと共に、火災発報を検出した火災検出器の両側に連続して隣接する所定数の火災検出器を火災判別候補に設定し、Ｒ型伝送部による火災判別候補に入る２台目の火災検出器の火災発報の検出を判別した場合、又は、Ｒ型伝送部による１台目の火災感知器の火災発報の検出とＲ型伝送部による任意の発信機の火災通報の検出の両方を判別した場合に、火災警報制御を行う制御部と、を設けるようにしたため、前述したＲ型トンネル防災システム１と同じ効果に加え、トンネル内での交通事故等により火災が発生した場合には、事故の関係者は例えば消火栓装置に設けている発信機を操作して通報する場合があることから、発信機による火災通報の検出を判別した場合に予備警報制御を行って注意を喚起し、続いて、火災検出器による火災発報の検出を判別した場合に、火災を確定して火災警報制御を行うことで、火災の進展状況に合わせて段階的に警報することで、火災の可能性を報知する予備警報の段階では管理担当者及びトンネル通行中の車両運転者等に注意を喚起して続いて予測される火災警報に対する心構えを促し、火災を判別して本警報が出された場合に必要な対処を迅速且つ適切に可能とし、不要な混乱を未然に防止可能とする。 (Effect of R type tunnel disaster prevention system 2)
Further, the present invention relates to a disaster prevention system in which a plurality of fire detectors and a plurality of transmitters installed in a tunnel are connected to a disaster prevention receiving board for monitoring. Multiple fire detectors and multiple transmitters are connected to the line, and fire alarms by the fire detector and fire reports by the transmitter are individually detected based on the prescribed transmission control between the fire detector and the transmitter. When the R type transmission unit and the R type transmission unit detect fire detection of the first fire detector or the R type transmission unit detects fire notification of the transmitter, preliminary alarm control is performed. Set the number of fire detectors that are adjacent to both sides of the fire detector that detected the fire alarm as fire discrimination candidates, and the fire of the second fire detector that enters the fire discrimination candidates by the R-type transmission unit When it is determined that a detection has been detected, or A control unit that performs fire alarm control when both the detection of the fire alarm of the first fire detector by the R-type transmission unit and the detection of the fire notification of an arbitrary transmitter by the R-type transmission unit are determined; In addition to the same effects as the R-type tunnel disaster prevention system 1 described above, when a fire occurs due to a traffic accident or the like in the tunnel, the person concerned in the accident, for example, a transmitter provided in a fire hydrant device Because it may be reported by operating, when the detection of the fire notification by the transmitter is determined, preliminary alarm control is performed to call attention, and then the detection of the fire notification by the fire detector is determined In this case, by confirming the fire and performing fire alarm control, it is alerted in stages according to the progress of the fire. Vehicle driver This alerts you to a preparedness for a fire alarm that can be predicted in advance, and enables you to quickly and appropriately take necessary actions when a fire is detected and this alarm is issued, preventing unnecessary confusion. And

また、発信機の操作は、利用者が火災現場から避難する途中で行う場合があることから、１台目の火災検出器の火災発報に基づき設定した火災判別候補に入る火災検出器から外れた位置の発信機の操作による火災通報であっても、火災として扱うことで、確実に火災警報を行うことを可能とする。   Also, because the transmitter may be operated while the user is evacuating from the fire site, the transmitter is not included in the fire detection candidate set based on the fire alarm of the first fire detector.

（ＰＲ型トンネル防災システム２の効果）
また、本発明は、防災受信盤に、トンネル内に設置した複数の火災検出器及び複数のポンプ起動操作手段を接続して監視するトンネル防災システムに於いて、防災受信盤に、トンネル内に引き出した伝送回線に複数の火災検出器を接続し、火災検出器との間で所定の伝送制御に基づき、火災検出器による火災発報を個別に検出するＲ型伝送部と、複数の発信機を１又は複数の区画に分け、トンネル内の区画単位に引き出した信号回線に同一の区画に入る複数のポンプ起動操作手段を接続し、ポンプ起動操作手段の操作によるポンプ起動を信号回線単位に検出するＰ型伝送部と、Ｒ型伝送部による１台目の火災感知器の火災発報の検出又はＰ型伝送部によるポンプ起動操作手段のポンプ起動を判別した場合に予備警報制御を行うと共に、火災発報を検出した火災検出器の両側に連続して隣接する所定数の火災検出器を火災判別候補に設定し、Ｒ型伝送部による火災判別候補に入る２台目の火災検出器の火災発報の検出を判別した場合、又は、Ｒ型伝送部による１台目の火災感知器の火災発報の検出とＰ型伝送部による火災判別候補に対応する区画のポンプ起動操作手段のポンプ起動の検出の両方を判別した場合に、火災警報制御を行う制御部と、を設けるようにしたため、前述したＲ型トンネル防災システム３と同じ効果に加え、火災検出器とその防災受信盤の伝送部をＲ型伝送方式の構成とし、それ以外の端末機器とその防災受信盤の伝送部をＰ型直送方式の構成とすることで、火災検出器の火災発報を個別に判別可能とする新たなＰ型直送方式の構成を必要とすることなく、簡単且つ容易に、隣接した複数の火災検出器の火災発報を判別可能なシステムを構成することができ、Ｒ型伝送方式はＰ型直送方式の一部で済むことから、全てＲ型伝送方式とした場合に比べ、コストの増加を必要最小限に抑えることを可能とする。 (Effects of PR type tunnel disaster prevention system 2)
In addition, the present invention provides a disaster prevention system for monitoring a disaster prevention receiver by connecting a plurality of fire detectors and a plurality of pump activation operation means installed in the tunnel to the disaster prevention receiver. Connect multiple fire detectors to the transmission line, and based on the prescribed transmission control with the fire detector, an R-type transmission unit that individually detects fire alarms by the fire detector, and multiple transmitters Dividing into one or a plurality of sections, connecting a plurality of pump activation operation means entering the same section to a signal line drawn out in the unit of a section in the tunnel, and detecting pump activation by operation of the pump activation operation means in signal line units When the fire alarm of the first fire detector is detected by the P-type transmission unit and the R-type transmission unit or when the pump activation of the pump activation operation means by the P-type transmission unit is determined, the preliminary alarm control is performed, and the fire Departure A predetermined number of fire detectors that are adjacent to both sides of the fire detector that detects the fire are set as fire discrimination candidates, and the fire detection of the second fire detector that enters the fire discrimination candidates by the R-type transmission unit When the detection is determined, or the detection of the fire detection of the first fire detector by the R-type transmission unit and the detection of the pump activation of the pump activation operation means of the section corresponding to the fire discrimination candidate by the P-type transmission unit In addition to the same effect as the R-type tunnel disaster prevention system 3 described above, the fire detector and the transmission part of its disaster prevention reception panel are R-type in addition to the control part that performs fire alarm control when both are discriminated.

Compared to the case, the increase in cost can be minimized.

（火災判別候補の設定による効果）
また、制御部は、火災判別候補として、火災発報を検出した火災検出器の両側に連続する１台または複数台の他の火災検出器を設定するようにしたため、１台目の火災検出器の火災発報の検出に続いて、隣接する複数台の火災検出器の火災発報の検出を判別することで、離れた場所に設置している火災検出器の火災以外の要因による火災発報があっても火災として扱うことがなく、火災判断の信頼性を向上可能とする。また、火災判別候補を火災発報を検出した火災検出器の両側に連続して隣接する２台の合計４台に設定した場合には、火災を起こした車両が走行している状況でも、確実に火災を判断して警報可能とする。 (Effects of setting fire detection candidates)
In addition, since the control unit is configured to set one or more other fire detectors continuous on both sides of the fire detector that has detected the fire alarm as a fire discrimination candidate, the first fire detector Fire detection due to factors other than fire of fire detectors installed at remote locations by determining the detection of fire alarms of multiple adjacent fire detectors Even if there is a fire, it will not be treated as a fire, and the reliability of fire judgment can be improved. In addition, when the number of fire detection candidates is set to a total of 4 units, which are adjacent to both sides of the fire detector that detects the fire alarm, a total of 4 units can be used reliably. A fire can be judged and an alarm is possible.

（火災判別候補外の２台目の火災発報による予備警報による効果）
また、制御部は、Ｒ型伝送部により１台目の火災検出器の火災発報の検出を判別して予備警報を行った後に、火災判別候補を外れた２台目の火災検出器の火災発報の検出を判別した場合は、予備警報より警報度合いの強い第２予備警報を行うことを可能としたため、設置場所が離れた２台の火災検出器による火災発報の検出であることから火災としては扱わないが、火災の可能性は１台の場合より高いことから、同じ予備警報であっても、警報度合いの強い予備警報とすることで、より強い注意喚起を促して想定される火災警報に対する準備を可能とする。 (Effect of preliminary warning by second fire alarm that is not a candidate for fire detection)
In addition, the control unit discriminates the detection of the fire alarm of the first fire detector by the R-type transmission unit and gives a preliminary alarm, and then the fire of the second fire detector that has missed the fire discrimination candidate When the detection of the alarm is determined, it is possible to perform the second preliminary alarm with a higher alarm level than the preliminary alarm. Although it is not treated as a fire, the possibility of a fire is higher than in the case of a single unit. Therefore, even if the same preliminary alarm is used, it is assumed that a strong alarm will be urged by using a strong alarm. Enables preparation for fire alarms.

（火災判別候補外のポンプ起動による予備警報による効果）
また、制御部は、Ｒ型伝送部により１台目の火災検出器の火災発報の検出を判別して予備警報を行った後に、火災判別候補に対応するポンプ起動操作手段を外れた他のポンプ起動操作手段のポンプ起動の検出を判別した場合は、予備警報より警報度合いの強い第２予備警報を行うことを可能としたため、火災発報を検出した場所が離れた場所でのポンプ起動の検出であることから火災としては扱わないが、火災の可能性は１台の火災検出器のよる火災発報の場合より高いことから、同じ予備警報であっても、警報度合いの強い予備警報とすることで、より強い注意喚起を促して想定される火災警報に対する準備を可能とする。 (Effect of preliminary alarm by starting pump outside fire detection candidate)
Further, the control unit discriminates the detection of the fire alarm of the first fire detector by the R-type transmission unit and gives a preliminary alarm, and then other pump start operation means corresponding to the fire discrimination candidate is removed. When the pump activation detection of the pump activation operation means is determined, the second preliminary alarm having a higher alarm level than the preliminary alarm can be performed, so that the pump activation at the location where the fire alarm is detected is remote. Because it is a detection, it is not treated as a fire, but the possibility of a fire is higher than in the case of a fire alarm with a single fire detector. By doing so, it is possible to prepare for a fire alarm that is expected by encouraging stronger attention.

（設備連動による予備警報と火災警報による効果）
また、制御部は、予備警報制御として複数の連動設備の中の一部の設備を連動制御し、火災警報制御として複数の連動設備の全てを連動制御するようにしたため、例えばＣＣＴＶ監視設備及び照明設備を一時的に明滅（フリッカ）させることで予備警報を出して注意を喚起し、また、全ての設備の連動制御により本警報としての通報を可能とし、設備連動を利用して、火災の進展状況に合わせて段階的に警報することで、例えば通常とは異なる設備の連動制御により、管理担当者及びトンネル通行中の車両運転者等に注意を喚起し、特に、トンネル内を走行中の車両の運転者は、予備警報及び本警報に伴い設備の連動制御による通常とは異なる設備の状態から異常を知って速度を落して注意しながら走行することを可能とし、また、トンネル進入しようとする車両の運転者は、トンネルに進入する前に異常に気付いて緊急停止するといった対処を可能し、火災に対する準備及び対処を迅速且つ適切に可能とする。 (Effects of preliminary alarm and fire alarm linked to equipment)
In addition, since the control unit interlocks and controls some of the plurality of interlocking facilities as the preliminary alarm control and controls all of the interlocking facilities as the fire alarm control, for example, the CCTV monitoring facility and the lighting Preliminary warnings are issued by temporarily flickering the equipment to call attention, and it is possible to report this alarm by interlocking control of all equipment. By alerting step by step according to the situation, for example, by using interlocking control of equipment that is different from usual, it alerts the manager in charge and the vehicle driver who is passing through the tunnel, in particular, the vehicle running in the tunnel The driver of the vehicle is able to travel with caution by reducing the speed and knowing the abnormality from the abnormal equipment state due to the interlocking control of the equipment accompanying the preliminary warning and the main warning. The driver of the vehicle to enter try is to enable addressing such an emergency stop noticing the abnormality before entering the tunnel, quickly and appropriately possible to prepare and Action against fire.

（火災検出器用のＲ型伝送部）
Ｒ型伝送部４２ａはＣＰＵによるプログラムの実行でＲ型の伝送制御を行って火災検出器１６の火災発報を個別に検出する。Ｒ型伝送部４２ａによる伝送制御は、所定周期毎にＲ型伝送回線１２ａに接続している火災検出器１６のアドレスを順次指定したポーリングコマンド信号を送信し、その応答信号から火災検出器１６の状態を検出している。 (R-type transmission unit for fire detector)
The R-type transmission unit 42a performs R-type transmission control by executing a program by the CPU, and individually detects fire alarms of the fire detector 16. In the transmission control by the R-type transmission unit 42a, a polling command signal in which addresses of the fire detectors 16 connected to the R-type transmission line 12a are sequentially specified is transmitted every predetermined cycle, and the response signal of the fire detector 16 is transmitted. A state is detected.

火災検出器１６が炎検出に基づき火災発報するとＲ型伝送回線１２ａに割込み信号を送信してくるので、Ｒ型伝送部４２ａは火災発報した火災検出器１６からの割込み信号を検出すると、グループ検索コマンド信号を送信して火災発報したグループを特定し、続いてグループ内検索コマンド信号を送信して火災発報した火災検出器１６のアドレスを検索することで、火災発報した火災検出器１６を特定する。   When the fire detector 16 issues a fire based on the flame detection, an interrupt signal is transmitted to the R-type transmission line 12a. Therefore, when the R-type transmission unit 42a detects an interrupt signal from the fire detector 16 that has issued the fire, A group search command signal is sent to identify the group that has fired, then a group search command signal is sent to search for the address of the fire detector 16 that has fired to detect the fire that has fired. The device 16 is identified.

（火災検出器以外の端末機器用のＲ型伝送部）
Ｒ型伝送部４２ｂはＣＰＵによるプログラムの実行でＲ型の伝送制御を行って火災検出器１６以外の端末機器の状態や操作を個別に検出すると共に端末機器の制御駆動を個別に行う。 (R-type transmission unit for terminal equipment other than fire detectors)
The R-type transmission unit 42b performs R-type transmission control by executing a program by the CPU, individually detects the state and operation of the terminal device other than the fire detector 16, and individually controls and drives the terminal device.

図３は、Ｒ型伝送機能を備えた消火栓装置及び自動弁装置の機能構成を示したブロック図である。   FIG. 3 is a block diagram showing a functional configuration of a fire hydrant device having an R-type transmission function and an automatic valve device.

図３に示すように、消火栓装置２０には、端末機器として、発信機５６、応答表示灯５８、消火栓弁開閉検出スイッチ６０及びポンプ起動スイッチ６２を設けており、消火栓装置２０に設けた中継器５４に回線単位に接続している。自動弁装置２２には、端末機器として、作動用電動弁６４と圧力スイッチ６７を設けており、自動弁装置２２に設けた中継器５４に回線単位に接続している。なお、中継器５４は消火栓装置２０と自動弁装置２２を一体化しても良い。   As shown in FIG. 3, the fire hydrant device 20 is provided with a transmitter 56, a response indicator light 58, a fire hydrant valve opening / closing detection switch 60, and a pump activation switch 62 as terminal devices, and a repeater provided in the fire hydrant device 20. 54 is connected to each line. The automatic valve device 22 is provided with an operating electric valve 64 and a pressure switch 67 as terminal devices, and is connected to a repeater 54 provided in the automatic valve device 22 in units of lines. The repeater 54 may integrate the fire hydrant device 20 and the automatic valve device 22 together.

中継器５４はＲ型防災受信盤１０Ａに設けたＲ型伝送部４２ｂとの間でＲ型伝送制御により信号の送受信を行うもので、固有のアドレスを予め設定している。   The repeater 54 transmits and receives signals by R-type transmission control with the R-type transmission unit 42b provided in the R-type disaster prevention receiving board 10A, and has a unique address set in advance.

図２に示したＲ型防災受信盤１０ＡのＲ型伝送部４２ｂは、消火栓装置２０及び自動弁装置２２に設けた中継器５４のアドレスを順次指定したポーリングコマンド信号を送信する。消火栓装置２０に設けた中継器５４は、自己アドレスを指定したポーリングコマンド信号を受信すると、そのときの発信機５６、消火栓弁開閉検出スイッチ６０及びポンプ起動スイッチ６２のスイッチのオン、オフ状態を示すスイッチ操作情報を含む応答信号を送信する。   The R-type transmission unit 42b of the R-type disaster prevention receiving board 10A shown in FIG. 2 transmits a polling command signal in which addresses of the repeaters 54 provided in the fire hydrant device 20 and the automatic valve device 22 are sequentially specified. When the repeater 54 provided in the fire hydrant device 20 receives the polling command signal designating its own address, it indicates the on / off state of the transmitter 56, the fire hydrant valve opening / closing detection switch 60 and the pump start switch 62 at that time. A response signal including switch operation information is transmitted.

例えば中継器５４は端末機器に引き出している４回線に対応した４ビット情報をもち、スイッチオンでビット１、スイッチオフでビット０にセットし、この４ビット情報を含む応答信号をＲ型防災受信盤１０Ａに応答送信する。   For example, the repeater 54 has 4-bit information corresponding to the 4 lines drawn out to the terminal equipment, and is set to bit 1 when switched on and bit 0 when switched off, and a response signal including this 4-bit information is received as an R-type disaster prevention reception. A response is transmitted to the board 10A.

中継器５４からの応答信号を受信したＲ型防災受信盤１０ＡのＲ型伝送部４２ｂは、応答信号に含まれる４ビット情報から発信機５６、消火栓弁開閉検出スイッチ６０及びポンプ起動スイッチ６２の状態を検出し、発信機５６の対応ビットがビット１であれば発信機５６の操作による火災通報を検出し、ポンプ起動手段として機能する消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２の対応ビットがビット１であれば、消火ポンプ設備に対するポンプ起動を検出する。   The R-type transmission unit 42b of the R-type disaster prevention receiving board 10A that has received the response signal from the repeater 54 determines the state of the transmitter 56, the fire hydrant valve opening / closing detection switch 60, and the pump start switch 62 from the 4-bit information included in the response signal. If the corresponding bit of the transmitter 56 is bit 1, a fire notification due to the operation of the transmitter 56 is detected, and the corresponding bit of the fire hydrant valve opening / closing detection switch 60 or the pump starting switch 62 functioning as a pump starting means is a bit. If 1, the pump activation for the fire pump facility is detected.

一方、消火栓装置２０に設けた応答表示灯５８は、発信機５６の操作による火災通報に対し確認応答のために点灯制御する。このためＲ型防災受信盤１０ＡのＲ型伝送部４２ａはポーリングコマンド信号に対する応答信号から発信機５６の火災通報を検出した場合、次にポーリング信号の送信タイミングで、応答表示灯５８に対応する制御ビットにビット１をセットした制御コマンド信号を送り、消火栓装置２０の中継器５４は制御コマンド信号を受信して制御ビット１に基づき、応答表示灯５８に対応した回線に駆動電圧を印加して応答表示灯５８を点灯する。   On the other hand, the response indicator lamp 58 provided in the fire hydrant device 20 controls the lighting for a confirmation response to the fire notification by the operation of the transmitter 56. For this reason, when the R-type transmission unit 42a of the R-type disaster prevention receiving panel 10A detects the fire notification of the transmitter 56 from the response signal to the polling command signal, the control corresponding to the response indicator lamp 58 at the next polling signal transmission timing. A control command signal with bit 1 set is sent, and the repeater 54 of the fire hydrant device 20 receives the control command signal and responds by applying a drive voltage to the line corresponding to the response indicator 58 based on the control bit 1 The indicator lamp 58 is turned on.

自動弁装置２２に設けた中継器５４も消火栓装置２０の場合と同様であり、中継器５４から端末機器側に引き出す４回線の内の２回線を使用して作動用電動弁６４と圧力スイッチ６７を接続している。   The repeater 54 provided in the automatic valve device 22 is the same as the case of the fire hydrant device 20, and the motor operated valve 64 and the pressure switch 67 are operated using two of the four lines drawn from the repeater 54 to the terminal device side. Is connected.

Ｒ型防災受信盤１０Ａで火災警報を出力した場合の担当者による水噴霧設備の区画を指定した放水起動操作等による起動条件の成立に基づきＲ型伝送部４２ｂが制御指示を受けると、自動弁装置２２にポーリングコマンド信号を送信するタイミングで、作動用電動弁６４に対応する開制御ビットにビット１をセットした制御コマンド信号を送り、自動弁装置２２の中継器５４は制御コマンド信号を受信して開制御ビット１に基づき、作動用電動弁６４に対応した回線に駆動電圧を印加して作動用電動弁６４を開駆動し、これに基づき主弁を開駆動して水噴霧ヘッドから消火用水をトンネル内に放水させる。
When the R-type transmission unit 42b receives a control instruction based on establishment of a start condition by a water discharge start operation or the like that designates a water spray facility section by a person in charge when a fire alarm is output from the R-type disaster prevention receiving panel 10A, an automatic valve At the timing when the polling command signal is transmitted to the device 22, a control command signal in which bit 1 is set to the open control bit corresponding to the motor operated valve 64 is sent, and the repeater 54 of the automatic valve device 22 receives the control command signal. Based on the opening control bit 1, a driving voltage is applied to the line corresponding to the operating motor operated valve 64 to open the operating motor operated valve 64 , and based on this, the main valve is driven to open the water for fire extinguishing from the water spray head. Water is discharged into the tunnel.

また、作動用電動弁６４を閉駆動する場合には、Ｒ型伝送部４２ｂは、閉制御ビットをビット１にセットした制御コマンド信号を送り、自動弁装置２２の中継器５４は受信した制御コマンド信号の閉制御ビット１に基づき、作動用電動弁６４に対応した回線に逆極性の駆動電圧を印加して作動用電動弁６４を閉駆動し、これに基づき主弁を閉駆動して水噴霧ヘッドから消火用水の放水を停止させる。
When the motor-operated valve for actuation 64 is driven to close, the R-type transmission unit 42b sends a control command signal with the closing control bit set to bit 1, and the repeater 54 of the automatic valve device 22 receives the received control command. Based on the signal close control bit 1, a drive voltage of reverse polarity is applied to the line corresponding to the motor operated valve 64 to drive the motor operated valve 64 closed, and based on this, the main valve is driven to close and water spray Stop water discharge from the head.

また、自動弁装置２２の中継器５４は、自己アドレスを指定したポーリングコマンド信号を受信すると、そのときの圧力スイッチ６７のオンでビット１、オフでビット０にセットし、このビット情報を含む応答信号をＲ型防災受信盤１０Ａに応答送信して、圧力検出による放水開始と停止を検出可能としている。   Further, when the relay device 54 of the automatic valve device 22 receives the polling command signal designating its own address, it sets bit 1 when the pressure switch 67 is turned on and bit 0 when turned off, and includes a response including this bit information. A signal is transmitted in response to the R-type disaster prevention receiving board 10A, so that the start and stop of water discharge by pressure detection can be detected.

［Ｒ型防災受信盤の監視制御］
図２に示したＲ型防災受信盤１０Ａの制御部４０は、端末機器として設けた火災検出器１６による火災発報、発信機５６による火災通報、消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２によるポンプ起動の検出に基づき、次の予備警報制御と火災警報制御を伴う監視制御を行う。
[Monitoring control of R-type disaster prevention receiver]
The control unit 40 of the R-type disaster prevention receiving board 10A shown in FIG. 2 is provided with a fire alarm by a fire detector 16 provided as a terminal device, a fire alarm by a transmitter 56, a fire hydrant valve opening / closing detection switch 60 or a pump start switch 62 . Based on the detection of pump activation, monitoring control with the following preliminary alarm control and fire alarm control is performed.

（予備警報制御）
Ｒ型防災受信盤１０Ａの制御部４０は、次の端末機器の状態検出を判別した場合、予備警報として扱い、所定の予備警報制御を行う。
（１）Ｒ型伝送部４２ａによる１台目の火災検出器１６の火災発報の検出、
（２）Ｒ型伝送部４２ｂよる火災通報の検出、
（３）Ｒ型伝送部４２ｂよるポンプ起動の検出、
制御部４０による予備警報制御は、警報部４５に指示して音声又はブザー等による警報と表示警報による予備火災警報（火災プリアラーム）を出力すると共に、設備連動による予備警報として、複数の連動設備の中の一部の設備を連動する制御を行う。 (Preliminary alarm control)
When the control unit 40 of the R-type disaster prevention receiving panel 10A determines that the state of the next terminal device is detected, it is treated as a preliminary alarm and performs predetermined preliminary alarm control.
(1) Detection of fire alarm of the first fire detector 16 by the R-type transmission unit 42a,
(2) Detection of fire notification by the R-type transmission unit 42b,
(3) Detection of pump activation by the R-type transmission unit 42b,
Preliminary alarm control by the control unit 40 instructs the alarm unit 45 to output an alarm by voice or buzzer, etc. and a preliminary fire alarm (fire prealarm) by display alarm, as well as a plurality of interlocking facilities as a preliminary alarm by facility interlocking Control that links some of the facilities.

この設備連動による予備警報として、制御部４０は、例えばＣＣＴＶ監視設備３４及び照明設備３６を所定の状態に連動させる制御を行う。予備警報としてのＣＣＴＶ監視設備３４の連動制御は、例えばモニタ画面に警報文字を表示するか、モニタ画面を明滅させるかして注意を喚起する。また予備警報としての照明設備３６の連動制御は、トンネル内に設置している照明機器を明滅するフリッカ点灯等により注意を喚起する。   As a preliminary alarm by this equipment interlocking, the control unit 40 performs control for interlocking the CCTV monitoring equipment 34 and the lighting equipment 36 to a predetermined state, for example. Interlocking control of the CCTV monitoring facility 34 as a preliminary alarm calls attention, for example, by displaying an alarm character on the monitor screen or blinking the monitor screen. Further, the interlocking control of the lighting equipment 36 as a preliminary warning alerts the attention by turning on flickers that blink the lighting equipment installed in the tunnel.

（２台の火災検出器に基づく火災警報制御）
Ｒ型防災受信盤１０Ａの制御部４０は、Ｒ型伝送部４２ａによる１台目の火災検出器１６による火災発報の検出を判別した場合、火災発報を検出した火災検出器１６の検出区画の両側に連続する１台または２台の火災検出器を火災判別候補に設定し、この状態で、Ｒ型伝送部４２ａにより火災判別候補に入る２台目の火災検出器１６による火災発報の検出を判別した場合、火災として扱い、所定の火災警報制御を行う。 (Fire alarm control based on two fire detectors)
When the control unit 40 of the R-type disaster prevention receiving panel 10A determines the detection of the fire alarm by the first fire detector 16 by the R-type transmission unit 42a, the detection section of the fire detector 16 that has detected the fire alarm One or two consecutive fire detectors on both sides of the fire detector are set as fire discrimination candidates. In this state, the fire detection by the second fire detector 16 that enters the fire discrimination candidate by the R-type transmission unit 42a. When the detection is determined, it is treated as a fire and predetermined fire alarm control is performed.

制御部４０による火災警報制御は、警報部４５に指示して音声又はブザー等による警報と表示警報による火災警報を出力すると共に、設備連動による火災警報として、換気設備２８、警報表示板設備３０、ラジオ再放送設備３２、ＣＣＴＶ監視設備３４及び照明設備３６の全てを連動する制御を行い、トンネル内に異常が起きていることを、トンネル内を走行している車両の運転者やトンネルに進入しようとしている車両の運転者に知らせ、徐行や緊急停止等の対処を可能とする。   The fire alarm control by the control unit 40 instructs the alarm unit 45 to output an alarm by voice or buzzer or the like and a fire alarm by display alarm, as well as a ventilation alarm 28, an alarm display board facility 30, Control all the radio re-broadcasting equipment 32, CCTV monitoring equipment 34, and lighting equipment 36 in an interlocked manner, and let us know that something is wrong in the tunnel and enter the driver or tunnel of the vehicle running in the tunnel. To the driver of the vehicle in question, and it is possible to deal with slowing down, emergency stop, etc.

図４は火災検出器の監視エリアと火災判別候補との関係を示した説明図である。図４に示すように、トンネル長手方向の側壁に沿って例えば火災検出器１６ｉ−２〜１６ｉ〜１６ｉ＋２を５０メートル間隔で配置しており、火災検出器１６ｉ−２〜１６ｉ〜１６ｉ＋２の監視エリアＡｉ−２〜Ａｉ〜Ａｉ＋２は隣接する間で相互に重複するようにしている。 FIG. 4 is an explanatory diagram showing the relationship between the fire detector monitoring area and the fire discrimination candidates. As shown in FIG. 4, for example, fire detectors 16 i−2 to 16 i to 16 i + 2 are arranged at intervals of 50 meters along the side wall in the longitudinal direction of the tunnel, and the fire detectors 16 i−2 to 16 i to The monitoring areas A i−2 to A i to A i + 2 of 16 i + 2 overlap each other between adjacent ones.

ここで、Ｒ型伝送部４２ａが１台目の火災検出器１６ｉの火災発報を検出したとすると、この火災発報の検出を判別した制御部４０は、火災検出器１６ ｉ の両側に隣接する１台の火災検出器１６ｉ−１，１６ｉ＋１の合計２台、または、火災検出器１６ ｉ の両側に隣接する２台の火災検出器１６ｉ−１，１６ｉ−１，１６ｉ＋１，１６ｉ＋１の合計４台を、火災判別候補に設定する。なお、以下の説明は、火災検出器１６ａの両側に隣接する１台の火災検出器１６ｉ−１，１６ｉ＋１の合計２台を火災判別候補に設定した場合を例に説明する。
Here, if the R-type transmitting unit 42a detects a fire alert the fire detector 16 i of first unit, the control unit 40 which determines the detection of the fire alert is on both sides of the fire detector 16 i total two adjacent fire detector 16 i-1 one, 16 i + 1, or, the fire detector 16 i-1 of two adjacent sides of the fire detector 16 i, 16 i-1, 16 i + 1 , 16 i + 1 are set as fire discrimination candidates. In the following description, a case where a total of two fire detectors 16 i-1 and 16 i + 1 adjacent to both sides of the fire detector 16a are set as fire discrimination candidates will be described as an example.

続いて、Ｒ型伝送部４２ａが２台目の火災検出器の火災発報を検出した場合、制御部４０は１台目の火災検出器１６ｉの火災発報の検出を判別して設定した火災判別候補に入る火災発報の検出か否か判断し、火災判別候補に入る火災検出器の火災発報の検出、即ち、隣接する火災検出器１６ｉ−１又は１６ｉ＋１の火災発報の検出を判別した場合は、火災と扱って火災警報制御を行う。 Subsequently, when detecting fire alert R-type transmission portion 42a are two-th fire detector, the control unit 40 was set to determine the first unit of the fire detector 16 i fire alarm detection of It is determined whether or not a fire alarm that enters a fire discrimination candidate is detected, and detection of a fire alarm of a fire detector that enters a fire discrimination candidate, that is, a fire alarm of an adjacent fire detector 16 i-1 or 16 i + 1 If the detection is determined, fire alarm control is performed by treating it as a fire.

一方、Ｒ型伝送部４２ａで検出した２台目の火災発報した火災検出器が火災判別候補に属しない離れた場所の火災検出器であった場合には、火災以外の要因により離れた場所の２台の火災検出器が火災発報したとみなし、この場合に火災としては扱わず、予備警報制御を維持する。   On the other hand, if the fire detector that triggered the second fire detected by the R-type transmission unit 42a is a remote fire detector that does not belong to the fire discrimination candidate, The two fire detectors are regarded as having fired, and in this case, they are not treated as a fire and the preliminary alarm control is maintained.

しかしながら、火災判別候補に属していないが、２台目の火災検出器で火災発報が行われていることから、火災の可能性は１台の火災発報よりも高いということができ、そこで、制御部４０は、１台目の火災検出器の火災発報の検出で行っている予備警報制御により警報度合いの強い予備警報制御を行う。   However, although it does not belong to the fire discrimination candidate, it can be said that the possibility of fire is higher than the one fire alarm because the fire alarm is being performed by the second fire detector. The control unit 40 performs preliminary alarm control with a strong alarm level by the preliminary alarm control performed by detecting the fire alarm of the first fire detector.

制御部４０による警報度合いの強い予備警報としては、例えばＲ型防災受信盤１０Ａで出力している予備警報音を強くしたり、予備警報表示の輝度を高くしたりし、また、設備連動による予備連動制御は、例えばＣＣＴＶ監視設備３４及び照明設備３６を所定の状態に連動させる予備警報制御から、設備を１つ追加して例えばＣＣＴＶ監視設備３４、照明設備３６及びラジオ再放送設備３２を所定の状態に連動させる警報度合いを強くした予備警報制御を行う。   As a preliminary alarm with a strong alarm level by the control unit 40, for example, the preliminary alarm sound output from the R-type disaster prevention reception panel 10A is strengthened, the brightness of the preliminary alarm display is increased, or the preliminary alarm by the facility interlocking is performed. The interlock control is, for example, a preliminary alarm control for interlocking the CCTV monitoring equipment 34 and the lighting equipment 36 to a predetermined state, and adding one equipment to make the CCTV monitoring equipment 34, the lighting equipment 36, and the radio re-broadcasting equipment 32 predetermined. Preliminary alarm control with a higher degree of alarm linked to the state is performed.

また、制御部４０による火災検出器１６ ｉ の両側に隣接する２台の火災検出器１６ｉ−２，１６ｉ−１，１６ｉ＋１，１６ｉ＋２の合計４台を、火災判別候補とする設定は、火災を起こした車両がトンネル内を走行する場合の火災の判別をより確実を行うことを可能とする。また、火災判別候補とする火災検出器の数は必要に応じて適宜に定めることができ、また、走行方向に対し両側の数が異なるように火災判別候補を設定しても良い。
Further, a total of four control unit 40 two fire detectors adjacent to each side of the fire detector 16 i by 16 i-2, 16 i- 1, 16 i + 1, 16 i + 2, set to fire discriminating candidate This makes it possible to more reliably determine the fire when the fired vehicle travels through the tunnel. In addition, the number of fire detectors to be fire discrimination candidates can be determined as needed, and the fire discrimination candidates may be set so that the numbers on both sides differ in the traveling direction.

（火災検出器と発信機に基づく火災警報制御）
また、Ｒ型防災受信盤１０Ａの制御部４０は、Ｒ型伝送部４２ａによる１台目の火災検出器１６による火災発報の検出を判別した状態で、Ｒ型伝送部４２ｂにより例えば消火栓装置２０に設けた発信機５６による火災通報の検出を判別した場合、火災として扱い、警報部４５に指示して音声又はブザー等による警報と表示警報による火災警報を出力すると共に、設備連動による火災警報として、換気設備２８、警報表示板設備３０、ラジオ再放送設備３２、ＣＣＴＶ監視設備３４及び照明設備３６の全てを連動する制御を行う。 (Fire alarm control based on fire detector and transmitter)
Further, the control unit 40 of the R-type disaster prevention receiving panel 10A determines, for example, that the fire detection by the first fire detector 16 has been detected by the R-type transmission unit 42a, and the R-type transmission unit 42b, for example, the fire hydrant device 20 If it is determined that a fire report is detected by the transmitter 56 provided in the system, it is treated as a fire, and the alarm unit 45 is instructed to output a voice or buzzer alarm and a display alarm. , The ventilation equipment 28, the alarm display board equipment 30, the radio rebroadcasting equipment 32, the CCTV monitoring equipment 34, and the lighting equipment 36 are all linked to perform control.

この場合、制御部４０は、図４に示したように、火災発報を検出した火災検出器１６ｉの両側に隣接する１台の火災感知器１６ｉ−１，１６ｉ＋１を火災判別候補に設定しているが、発信機５６の操作による火災通報の検出については、車両事故等で発生した火災場所から利用者が避難する途中で、消火栓装置２０に設けている発信機５６を操作して火災通報する場合があることから、火災判別候補の設定により制約は解除し、任意の発信機５６による火災通報の検出を判別して火災警報制御を行う。 In this case, as shown in FIG. 4, the control unit 40 sets one fire detector 16 i−1 , 16 i + 1 adjacent to both sides of the fire detector 16 i that has detected the fire alarm as a fire discrimination candidate. Although it is set, the detection of fire notification by operating the transmitter 56 is performed by operating the transmitter 56 provided in the fire hydrant device 20 while the user is evacuating from a fire place caused by a vehicle accident or the like. Since there is a case where a fire report is issued, the restriction is released by setting a fire determination candidate, and the detection of the fire report by an arbitrary transmitter 56 is determined, and fire alarm control is performed.

（火災検出器とポンプ起動操作手段に基づく火災制御）

A fire alarm is output, and then in S6, a fire alarm is performed by interlocking control of all facilities. Thereafter, when the fire is extinguished and restoration is determined in S7, the R-type disaster prevention receiving board 10A is restored and the process is terminated.

一方、制御部４０は、Ｓ４で他の火災検出器１６の火災発報の検出を判別しない場合はＳ８，Ｓ９の処理をループしており、Ｓ８でＲ型伝送部４２ｂによる発信機５６の操作による火災通報の検出を判別すると、火災判別候補を考慮することなくＳ５に進み、警報部４５に指示して火災警報を出力させ、次いでＳ６で全設備の連動制御による火災警報を行う。   On the other hand, the control unit 40 loops the processes of S8 and S9 when it does not determine the detection of the fire alarm of the other fire detector 16 in S4, and the operation of the transmitter 56 by the R-type transmission unit 42b in S8. If it is determined that the fire notification is detected, the process proceeds to S5 without considering the fire determination candidate, instructs the alarm unit 45 to output the fire alarm, and then performs the fire alarm by interlocking control of all facilities in S6.

また、制御部４０は、Ｓ９で消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２の操作によるポンプ起動のＲ型伝送部４２ｂによる検出を判別すると、Ｓ１０で制御部４０はＰ型伝送部５２に指示してポンプ起動信号を消火ポンプ設備に出力し、Ｓ１１で区画内の火災検出器１６ｉ及び隣接区画の火災判別候補に入る火災検出器１６ｉ−１，１６ｉ＋１に対応した消火栓装置２０ｉ−２，〜２０ｉ＋２の何れかに設けた消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２の操作によるポンプ起動のＲ型伝送部４２ｂによる検出を判別するとＳ５に進み、警報部４５に指示して火災警報を出力させ、次いでＳ６で全設備の連動制御による火災警報を行う。 Further, when the control unit 40 determines that the R-type transmission unit 42b detects that the pump is started by operating the fire hydrant valve opening / closing detection switch 60 or the pump activation switch 62 in S9, the control unit 40 instructs the P-type transmission unit 52 in S10. and it outputs a pump start signal to the fire pump facilities, fire hydrant apparatus corresponding to the fire detector 16 i-1, 16 i + 1 entering the fire detector 16 i and the adjacent section fire discrimination candidates in the compartment at S11 20 i- 2 , ~ 20 i + 2 If the detection by the R-type transmission part 42b of the pump start by the operation of the fire hydrant valve opening / closing detection switch 60 or the pump start switch 62 provided in any one is determined, the process proceeds to S5, the alarm part 45 is instructed An alarm is output, and then in S6, a fire alarm is performed by interlocking control of all facilities.

If it is determined, the process proceeds to S13, and a preliminary fire alarm is output from the alarm unit 45 in the same manner as in S2. Subsequently, the process proceeds to S14, and CCTV monitoring that becomes part of the equipment via the P-type transmission unit 52 is performed in the same manner as in S3. Control is performed to alert the facility 34 and the lighting facility 36 by a preliminary alarm that links the facility 34 and the lighting facility 36 to a predetermined state.

次いで、制御部４０は、Ｓ１５に進み、Ｒ型伝送部４２ａによる火災検出器１６の火災発報の検出を判別すると、発信機５６による火災通報と１台目の火災感知器１６の火災発報の検出の両方の判別となることからＳ５に進み、警報部４５に指示して火災警報を出力させ、次いでＳ６で全設備の連動制御による火災警報を行う。
Next, when the control unit 40 proceeds to S15 and determines that the fire detection of the fire detector 16 by the R-type transmission unit 42a is detected, the fire notification by the transmitter 56 and the fire notification of the first fire detector 16 are detected. Therefore, the process proceeds to S5, where the alarm unit 45 is instructed to output a fire alarm, and then in S6, a fire alarm is performed by interlocking control of all facilities.

また、制御部４０は、Ｓ１２でＲ型伝送部４２ｂによる発信機５６の火災通報の検出を判別しない場合はＳ１６に進み、Ｒ型伝送部４２ｂによる消火栓装置２０に設けた消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２の操作によるポンプ起動の検出を判別すると、Ｓ１７で消火ポンプ設備２４の起動制御を行ってＳ１７に進み、Ｓ３と同様に、Ｐ型伝送部５２を介して設備の一部となるＣＣＴＶ監視設備３４及び照明設備３６を所定の状態に連動させる予備警報により注意を喚起する制御を行う。
Further, when the control unit 40 does not discriminate the detection of the fire notification of the transmitter 56 by the R-type transmission unit 42b in S12, the control unit 40 proceeds to S16, and the fire hydrant valve opening / closing detection switch 60 provided in the fire hydrant device 20 by the R-type transmission unit 42b. Alternatively, when it is determined that the pump activation is detected by operating the pump activation switch 62 , the activation control of the fire-extinguishing pump facility 24 is performed in S17, and the process proceeds to S17. The CCTV monitoring equipment 34 and the lighting equipment 36 are controlled so as to call attention by a preliminary alarm for interlocking with a predetermined state.

次いでＳ１９に進み、図５に示したように、ポンプ起動を検出した消火栓装置２０ｉに対応した火災検出器１６ｉ及び両側に隣接する火災検出器１６ｉ−１，１６ｉ＋１を含む火災判別候補を設定し、Ｒ型伝送部４２ａによる火災判別候補に入る設置区画対応の火災検出器１６ｉ−１，１６ｉ，１６ｉ＋１の何れかによる火災発報の検出を判別すると、消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２の操作によるポンプ起動の検出と１台の火災感知器１６の火災発報の検出との両方の判別となることからＳ５に進み、警報部４５に指示して火災警報を出力させ、次いでＳ６で全設備の連動制御による本警報を行う。 Next, in S19, as shown in FIG. 5, the fire discrimination candidates including fire detector 16 i-1, 16 i + 1 adjacent to the fire detector 16 i and the side corresponding to the fire hydrant apparatus 20 i detects a pump start When the fire alarm detection by any of the fire detectors 16 i-1 , 16 i , 16 i + 1 corresponding to the installation section entering the fire discrimination candidate by the R-type transmission unit 42a is discriminated, 60 or the operation of the pump start switch 62, so that both the detection of the pump start and the detection of the fire alarm of one fire sensor 16 are detected, so that the process proceeds to S5 and the alarm unit 45 is instructed to issue a fire alarm. Next, in S6, this alarm is performed by interlocking control of all facilities.

［ＰＲ型トンネル防災システムの概要］
図７はＰＲ型トンネル防災システムの概要を示した説明図である。本実施形態のＰＲ型トンネル防災システムは、トンネル内に設置した火災検出器にＲ型伝送方式を適用し、火災感知器以外の端末機器にＰ型直送方式を適用しており、Ｐ型とＲ型を混在したトンネル防災システムということができる。 [Outline of PR type disaster prevention system]
FIG. 7 is an explanatory view showing an outline of the PR type tunnel disaster prevention system. The PR type tunnel disaster prevention system of this embodiment applies the R type transmission method to the fire detector installed in the tunnel, and applies the P type direct transmission method to terminal devices other than the fire detector. It can be said that it is a tunnel disaster prevention system with mixed types.

図７に示すように、トンネルは図１と同じであり、上り線トンネル１ａと下り線トンネル１ｂの内部には、トンネル長手方向の壁面に沿って例えば５０メートル間隔でアドレスを設定した火災検出器１６を設置し、また、５０メートル間隔で消火栓装置２０と自動弁装置２２を設置している。消火栓装置２０は端末機器として、発信機、消火栓弁開閉検出スイッチ、及びポンプ起動スイッチを備え、また、自動弁装置２２は端末機器として作動用電動弁を備えている。   As shown in FIG. 7, the tunnel is the same as in FIG. 1, and fire detectors in which addresses are set at intervals of, for example, 50 meters along the walls in the longitudinal direction of the tunnel inside the upstream tunnel 1a and the downstream tunnel 1b. 16 and the fire hydrant device 20 and the automatic valve device 22 are installed at intervals of 50 meters. The fire hydrant device 20 includes a transmitter, a fire hydrant valve opening / closing detection switch, and a pump start switch as terminal devices, and the automatic valve device 22 includes an electrically operated valve for operation as a terminal device.

なお、システム的には消火栓弁開閉検出スイッチとポンプ起動スイッチは同一信号となることから、以下、消火栓弁開閉検出スイッチ（ポンプ起動スイッチを含む）として説明する。   In terms of the system, the fire hydrant valve opening / closing detection switch and the pump activation switch have the same signal, and therefore the following description will be given as a fire hydrant valve opening / closing detection switch (including a pump activation switch).

監視センター等に設置したＰＲ型防災受信盤１０Ｂからは、上り線トンネル１ａと下り線トンネル１ｂの内に、Ｒ型伝送回線１２を引き出し、トンネル内に設置した火災検出器１６を接続している。また、Ｒ型伝送回線１２の途中には中継増幅盤１８を設け、遠方に設置して火災検出器１６との間で送受信する信号を中継増幅している。Ｒ型伝送回線１２は、例えば電源線、コモン線、端末側に電圧モードで信号を送る下り信号線、端末から電流モードで信号を送り返す上り信号線で構成している。   From the PR type disaster prevention receiving board 10B installed in the monitoring center or the like, the R type transmission line 12 is drawn out of the upstream tunnel 1a and the downstream tunnel 1b, and the fire detector 16 installed in the tunnel is connected. . In addition, a relay amplifier board 18 is provided in the middle of the R-type transmission line 12, and is installed far away to relay and amplify signals transmitted to and received from the fire detector 16. The R-type transmission line 12 includes, for example, a power line, a common line, a downstream signal line that transmits a signal to the terminal side in a voltage mode, and an upstream signal line that transmits a signal back from the terminal in a current mode.

また、火災検出器１６の動作に問題のない伝送距離の場合には、中継増幅盤１８を設けなくとも良い。中継増幅盤１８を設けないと、Ｒ型伝送回線１２の断線補償ができなくなるが、断線補償を行っていないＰ型信号回線と同等の信頼性は確保できる。
Further, in the case of a transmission distance that does not cause a problem in the operation of the fire detector 16, the relay amplifier board 18 may not be provided. If the relay amplifier panel 18 is not provided, disconnection compensation for the R-type transmission line 12 cannot be performed, but reliability equivalent to that of the P-type signal line without disconnection compensation can be ensured.

また、ＰＲ型防災受信盤１０Ｂからは上り線トンネル１ａと下り線トンネル１ｂの内に、ｎ回線分のＰ型信号回線１４を引き出している。Ｐ型信号回線１４は、火災検出器１６以外の端末機器を対象に、トンネル内を長手方向に分割した１又は複数の端末機器を含む区画と、端末機器の種別とに分けて、専用の信号回線を複数本引き出している。
In addition, P-type signal lines 14 for n lines are drawn out from the PR-type disaster prevention receiving board 10B into the uplink tunnel 1a and the downlink tunnel 1b. The P-type signal line 14 is intended for terminal equipment other than the fire detector 16, and is divided into a section including one or a plurality of terminal equipment obtained by dividing the inside of the tunnel in the longitudinal direction, and a type of terminal equipment. Pulls out multiple lines.

火災検出器１６以外の端末機器としては、消火栓装置２０に設けた発信機、消火栓弁開閉検出スイッチ（ポンプ起動スイッチを含む）、及び自動弁装置２２に設けた作動用電動弁と圧力スイッチがあることから、発信機、消火栓弁開閉検出スイッチ（ポンプ起動スイッチを含む）、作動用電動弁及び圧力スイッチの種別毎に分けてＰ型信号回線１４を引き出し、更に、各種別につき、トンネル長手方向の区間に分けて同じＰ型信号回線１４に区間内の端末機器を接続している。   As terminal devices other than the fire detector 16, there are a transmitter provided in the fire hydrant device 20, a fire hydrant valve opening / closing detection switch (including a pump start switch), and a motor operated valve and a pressure switch provided in the automatic valve device 22. Therefore, the P-type signal line 14 is pulled out for each type of transmitter, fire hydrant valve opening / closing detection switch (including pump start switch), motor operated valve and pressure switch. The terminal devices in the section are connected to the same P-type signal line 14 divided into sections.

なお、自動弁装置２２は１区画に１台としており、このため自動弁装置２２に設けた作動用電動弁と圧力スイッチ毎にＰ型信号回線１４を引き出して接続している。   Note that one automatic valve device 22 is provided for each section. For this reason, the P-type signal line 14 is pulled out and connected to the operating electric valve provided in the automatic valve device 22 for each pressure switch.

Ｐ型信号回線１４は信号線とコモン線で構成し、発信機、消火栓弁開閉検出スイッチ（ポンプ起動スイッチを含む）、圧力スイッチを接続した場合は、それぞれのオン操作に基づき回線電流を流すことで、火災通報信号やスイッチオン信号をＰＲ型防災受信盤１０Ｂに送るようにしている。また、自動弁装置２２に設けた作動用電動弁の場合には、ＰＲ型防災受信盤１０ＢからＰ型信号回線１４を介して開制御信号として駆動電圧を印加することで、作動用電動弁を開駆動させるようにしている。
The P-type signal line 14 is composed of a signal line and a common line. When a transmitter, a fire hydrant valve open / close detection switch (including a pump start switch), and a pressure switch are connected, a line current is passed based on the respective ON operations. Therefore, a fire notification signal and a switch-on signal are sent to the PR type disaster prevention receiving board 10B. In the case of actuating the electric valve provided in the automatic valve device 22, by via a P-type signal line 14 from the PR type disaster received Release 10 B for applying a driving voltage as opening control signal, actuating electric valve Is driven to open.

またトンネルの非常用施設として、図１と同様に、火災検出器１６、消火栓装置２０及び自動弁装置２２以外に、消火ポンプ設備２４、ＩＧ子局設備２６、換気設備２８、警報表示板設備３０、ラジオ再放送設備３２、ＣＣＴＶ監視設備３４及び照明設備３６等を設け、ＩＧ子局設備２６をデータ伝送回線で接続する点を除き、それ以外の設備はＰ型信号回線１４により防災受信盤１０に個別に接続している。なお、消火ポンプ設備２４はＲ型伝送とする場合がある。   In addition to the fire detector 16, the fire hydrant device 20, and the automatic valve device 22, as the emergency facility for the tunnel, in addition to the fire detector 16, the fire hydrant device 20, the IG slave station facility 26, the ventilation facility 28, and the alarm display board facility 30. The radio re-broadcasting facility 32, the CCTV monitoring facility 34, the lighting facility 36, etc. are provided, and the other facilities are connected by the P-type signal line 14 except for the point that the IG slave station facility 26 is connected by a data transmission line. Are connected individually. The fire pump 24 may be R-type transmission.

受信回路７０から引き出したＰ型信号回線１４ａには同一区画に属し且つ同じ種別の端末機器として、複数の消火栓装置２０に設けた複数の発信機５６を並列接続している。このため同じ区画に属する複数の発信機５６の何れかの押し釦操作によりスイッチがオンすると、Ｐ型信号回線１４ａに回線電流が流れることで受信回路７０が火災通報信号を受信し、区画を特定した火災通報の検出信号を出力する。   A plurality of transmitters 56 provided in the plurality of fire hydrant apparatuses 20 are connected in parallel to the P-type signal line 14a drawn from the receiving circuit 70 as terminal devices belonging to the same section and of the same type. For this reason, when the switch is turned on by operating one of the push buttons of a plurality of transmitters 56 belonging to the same section, a line current flows through the P-type signal line 14a, so that the receiving circuit 70 receives the fire notification signal and identifies the section. A fire alarm detection signal is output.

また、受信回路７２から引き出したＰ型信号回線１４ｂには同一区画に属し且つ同じ種別の端末機器として、複数の消火栓装置２０に設けた複数の消火栓弁開閉検出スイッチ６０とポンプ起動スイッチ６２のそれぞれを並列接続している。ここで、消火栓弁開閉検出スイッチ６０とポンプ起動スイッチ６２は、火災に関連する操作に基づきポンプ起動のための火災操作信号を出力するものであり、ポンプ起動操作手段として共通していることから同じ種別としており、このため同種の端末機器として同じＰ型信号回線１４ｂに並列接続している。
The P-type signal line 14b drawn from the receiving circuit 72 includes a plurality of fire hydrant valve opening / closing detection switches 60 and pump activation switches 62 provided in the plurality of fire hydrant devices 20 as terminal devices belonging to the same section and of the same type. Are connected in parallel. Here, the hydrant valve opening / closing detection switch 60 and the pump start switch 62 output a fire operation signal for starting the pump based on an operation related to fire, and are the same because they are common as pump start operation means. For this reason, the same type of terminal device is connected in parallel to the same P-type signal line 14b.

このため利用者が消火栓装置２０のノズル付きホースを引き出して消火栓弁開閉レバーを操作した場合に、消火栓弁開閉検出スイッチ６０がオンしてＰ型信号回線１４ｂに回線電流が流れることで、受信回路７２がポンプ起動信号を受信し、区画を特定したポンプ起動の検出信号を出力する。また、消防隊員が消火栓装置２０の扉を開いて給水栓に消防ホースを接続し、ポンプ起動スイッチ６２をオン操作した場合にも、Ｐ型信号回線１４ｂに回線電流が流れることで、受信回路７２がポンプ起動信号を受信し、区画を特定したポンプ起動の検出信号を出力する。   For this reason, when the user pulls out the hose with a nozzle of the fire hydrant device 20 and operates the fire hydrant valve opening / closing lever, the fire hydrant valve opening / closing detection switch 60 is turned on and a line current flows through the P-type signal line 14b. 72 receives the pump start signal and outputs a pump start detection signal specifying the section. Even when the fire brigade opens the door of the fire hydrant device 20, connects the fire hose to the water tap, and turns on the pump start switch 62, the line current flows through the P-type signal line 14b. Receives the pump activation signal and outputs a pump activation detection signal specifying the section.

更に、送信回路７４から引き出したＰ型信号回線１４ｃには、１区画に１台の自動弁装置２２に設けた作動用電動弁６４を接続しており、ＰＲ型防災受信盤１０Ｂで火災警報を出力した場合の担当者による水噴霧設備の区画を指定した放水起動操作等による起動条件の成立に基づき開制御指示を受けた送信回路７４がＰ型信号回線１４ｃに駆動電圧を印加することで開制御信号を送信し、自動弁装置２２の作動用電動弁６４を開制御することで主弁を開駆動し、水噴霧ヘッドからトンネル内に消火用水を放水させる。   In addition, the P-type signal line 14c drawn from the transmission circuit 74 is connected to a motor-operated valve 64 provided in one automatic valve device 22 in one section, and a fire alarm is issued by the PR-type disaster prevention receiving panel 10B. When the transmission circuit 74 receives the opening control instruction based on the establishment of the starting condition by the water discharge starting operation or the like designating the water spray equipment section by the person in charge when the output is made, the transmitting circuit 74 applies the drive voltage to the P-type signal line 14c. A control signal is transmitted, and the main valve is driven to open by controlling the motor-operated valve 64 of the automatic valve device 22 to open, and water for fire extinguishing is discharged from the water spray head into the tunnel.

またＰＲ型防災受信盤１０Ｂから閉制御指示を受けた送信回路７４がＰ型信号回線１４ｃに極性を逆転した駆動電圧を印加することで閉制御信号を送信し、自動弁装置２２の作動用電動弁６４を閉制御することで主弁を閉駆動し、水噴霧ヘッドからトンネル内に放水していた消火用水を停止させる。   The transmission circuit 74 that has received a closing control instruction from the PR type disaster prevention receiving panel 10B transmits a closing control signal by applying a driving voltage with the polarity reversed to the P type signal line 14c, and the motor for operating the automatic valve device 22 is operated. By closing the valve 64, the main valve is driven to close, and the fire-fighting water discharged from the water spray head into the tunnel is stopped.

なお、自動弁装置２２には、図３に示したように、作動用電動弁６４と圧力スイッチ６７を設け、区画モジュール６８に設けた受信回路から引き出されたＰ型信号線に接続しているが、図示は省略している。
As shown in FIG. 3, the automatic valve device 22 is provided with an operating electric valve 64 and a pressure switch 67, and is connected to a P-type signal line drawn from a receiving circuit provided in the partition module 68. However, illustration is omitted.

［ＰＲ型防災受信盤による監視制御］
図８に示したＰＲ型防災受信盤１０Ｂの制御部４０は、端末機器として設けた火災検出器１６による火災発報、発信機５６による火災通報、消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２によるポンプ起動の検出に基づき、次の監視制御を行う。 [Monitoring control by PR type disaster prevention receiver]
The control unit 40 of the PR type disaster prevention receiving board 10B shown in FIG. 8 is provided with a fire alarm by a fire detector 16 provided as a terminal device, a fire alarm by a transmitter 56, a fire hydrant valve opening / closing detection switch 60 or a pump start switch 62. Based on the detection of pump activation, the following monitoring control is performed.

（予備警報制御）
ＰＲ型防災受信盤１０Ｂの制御部４０は、次の端末機器の状態検出を判別した場合、予備警報として扱い、所定の予備警報制御を行う。
（１）Ｒ型伝送部４２による１台目の火災検出器１６の火災発報の検出
（２）Ｐ型伝送部４４よる１区画（１回線）の火災通報の検出
（３）Ｐ型伝送部４４よる１区画（１回線）のポンプ起動の検出
制御部４０による予備警報制御は、警報部４５に指示して音声又はブザー等による警報と表示警報による予備火災警報（火災プリアラーム）を出力すると共に、設備連動による予備警報として、複数の連動設備の中の一部の設備を連動する制御を行う。 (Preliminary alarm control)
The control unit 40 of the PR-type disaster prevention receiving board 10B treats it as a preliminary alarm when determining the state detection of the next terminal device, and performs predetermined preliminary alarm control.
(1) Detection of fire notification of the first fire detector 16 by the R-type transmission unit 42 (2) Detection of fire notification of one section (one line) by the P-type transmission unit 44 (3) P-type transmission unit 44. Detection of pump activation of one section (1 line) by 44. Preliminary alarm control by the control unit 40 instructs the alarm unit 45 to output an alarm by a voice or buzzer and a preliminary fire alarm (fire prealarm) by a display alarm. At the same time, control is performed to link some of the multiple interlocking facilities as a preliminary alarm by interlocking with the facilities.

この設備連動による予備警報として、制御部４０は、例えばＣＣＴＶ監視設備３４及び照明設備３６を所定の状態に連動させる制御を行う。予備警報としてのＣＣＴＶ監視設備３４の連動制御は、例えばモニタ画面に警報文字を表示するか、モニタ画面を明滅させるかして注意を喚起する。また予備警報としての照明設備３６の連動制御は、トンネル内に設置している照明機器を明滅するフリッカ点灯等といて注意を喚起する。   As a preliminary alarm by this equipment interlocking, the control unit 40 performs control for interlocking the CCTV monitoring equipment 34 and the lighting equipment 36 to a predetermined state, for example. Interlocking control of the CCTV monitoring facility 34 as a preliminary alarm calls attention, for example, by displaying an alarm character on the monitor screen or blinking the monitor screen. Further, the interlocking control of the lighting equipment 36 as a preliminary alarm calls attention by turning on the flicker that blinks the lighting equipment installed in the tunnel.

（２台の火災検出器に基づく火災警報制御）
ＰＲ型防災受信盤１０Ｂの制御部４０は、Ｒ型伝送部４２による１台目の火災検出器１６による火災発報の検出を判別した場合、図４に示したと同様に、火災検出器１６ ｉ の両側に隣接する１台の火災検出器１６ｉ−１，１６ｉ＋１の合計２台、または、火災検出器１６ ｉ の両側に連続して隣接する２台の火災検出器１６ｉ−２，１６ｉ−１，１６ｉ＋１，１６ｉ＋２の合計４台を、火災判別候補に設定する。なお、以下の説明は、火災検出器１６ａの両側に隣接する１台の火災検出器１６ｉ−１，１６ｉ＋１の合計２台を火災判別候補に設定した場合を例に説明する。
(Fire alarm control based on two fire detectors)
When the control unit 40 of the PR-type disaster prevention receiving board 10B determines that the first fire detector 16 detects the fire alarm by the R-type transmission unit 42, the fire detector 16 i is the same as shown in FIG. 2 fire detectors 16 i-1 and 16 i + 1 adjacent to both sides of the fire detector 16 i in total, or two fire detectors 16 i-2 and 16 adjacent to both sides of the fire detector 16 i in succession. A total of four units, i−1 , 16 i + 1 , and 16 i + 2 , are set as fire discrimination candidates. In the following description, a case where a total of two fire detectors 16 i-1 and 16 i + 1 adjacent to both sides of the fire detector 16a are set as fire discrimination candidates will be described as an example.

続いて制御部４０は、火災判別候補を設定した状態で、Ｒ型伝送部４２により火災判別候補に入る２台目の火災検出器１６ｉ−１，１６ｉ＋１の何れかによる火災発報の検出を判別した場合、火災として扱い、所定の火災警報制御を行う。 Subsequently, the control unit 40 detects a fire alarm by one of the second fire detectors 16 i-1 and 16 i + 1 entering the fire discrimination candidate by the R-type transmission unit 42 in a state where the fire discrimination candidate is set. If it is determined, it is treated as a fire and predetermined fire alarm control is performed.

制御部４０による火災警報制御は、警報部４５に指示して音声又はブザー等による警報と表示警報による火災警報を出力すると共に、設備連動による火災警報として、換気設備２８、警報表示板設備３０、ラジオ再放送設備３２、ＣＣＴＶ監視設備３４及び照明設備３６の全てを連動する制御を行い、トンネル内に異常が起きていることを、トンネル内を走行している車両の運転者やトンネルに進入しようとしている車両の運転者に知らせ、徐行や緊急停止等の対処を可能とする。   The fire alarm control by the control unit 40 instructs the alarm unit 45 to output an alarm by voice or buzzer or the like and a fire alarm by display alarm, as well as a ventilation alarm 28, an alarm display board facility 30, Control all the radio re-broadcasting equipment 32, CCTV monitoring equipment 34, and lighting equipment 36 in an interlocked manner, and let us know that something is wrong in the tunnel and enter the driver or tunnel of the vehicle running in the tunnel. To the driver of the vehicle in question, and it is possible to deal with slowing down, emergency stop, etc.

一方、Ｒ型伝送部４２で検出した２台目の火災発報した火災検出器が火災判別候補に入らない離れた場所の火災検出器であった場合には、火災以外の要因により離れた場所の２台の火災検出器が火災発報したとみなし、この場合に火災としては扱わず、予備警報制御を維持する。   On the other hand, if the fire detector that triggered the second fire detected by the R-type transmission unit 42 is a remote fire detector that does not enter the fire discrimination candidate, The two fire detectors are regarded as having fired, and in this case, they are not treated as a fire and the preliminary alarm control is maintained.

しかしながら、火災判別候補に属していないが、２台目の火災検出器で火災発報が行われていることか、火災の可能性は１台の火災発報よりも高いということができ、そこで、制御部４０は、１台目の火災検出器の火災発報の検出で行っている予備警報制御により警報度合いの強い予備警報制御を行う。   However, although it does not belong to the fire detection candidate, it can be said that the fire alarm is being performed by the second fire detector, or that the possibility of fire is higher than the one fire alarm. The control unit 40 performs preliminary alarm control with a strong alarm level by the preliminary alarm control performed by detecting the fire alarm of the first fire detector.

制御部４０による警報度合いの強い予備警報としては、例えばＰＲ型防災受信盤１０Ｂで出力している予備警報音を強くしたり、予備警報表示の輝度を高くしたりし、また、設備連動による予備連動制御は、例えばＣＣＴＶ監視設備３４及び照明設備３６を所定の状態に連動させる予備警報制御から、設備を１つ追加して例えばＣＣＴＶ監視設備３４、照明設備３６及びラジオ再放送設備３２を所定の状態に連動させる警報度合いを強くした予備警報制御を行う。   As a preliminary warning with a high degree of warning by the control unit 40, for example, the preliminary warning sound output from the PR type disaster prevention receiving panel 10B is strengthened, the brightness of the preliminary warning display is increased, or the preliminary warning by the facility interlocking is performed. The interlock control is, for example, a preliminary alarm control for interlocking the CCTV monitoring equipment 34 and the lighting equipment 36 to a predetermined state, and adding one equipment to make the CCTV monitoring equipment 34, the lighting equipment 36, and the radio re-broadcasting equipment 32 predetermined. Preliminary alarm control with a higher degree of alarm linked to the state is performed.

（火災検出器と発信機に基づく火災警報制御）
また、ＰＲ型防災受信盤１０Ｂの制御部４０は、Ｒ型伝送部４２による１台目の火災検出器１６による火災発報の検出を判別した状態で、Ｐ型伝送部４４により例えば消火栓装置２０に設けた発信機５６の操作で図９のＰ型信号回線１４ａによる火災通報の検出を判別した場合、火災として扱い、警報部４５に指示して音声又はブザー等による警報と表示警報による火災警報を出力すると共に、設備連動による火災警報として、換気設備２８、警報表示板設備３０、ラジオ再放送設備３２、ＣＣＴＶ監視設備３４及び照明設備３６の全てを連動する制御を行う。 (Fire alarm control based on fire detector and transmitter)
In addition, the control unit 40 of the PR-type disaster prevention receiving panel 10B determines, for example, that the fire detection by the first fire detector 16 by the R-type transmission unit 42 has been detected, and the P-type transmission unit 44 performs, for example, the fire hydrant device 20. If it is determined by the operation of the transmitter 56 provided in FIG. 9 that a fire report is detected by the P-type signal line 14a of FIG. 9, it is treated as a fire, and the alarm unit 45 is instructed to give a voice or buzzer alarm and a display alarm. In addition, as a fire alarm by interlocking with the equipment, control is performed to interlock all of the ventilation equipment 28, the alarm display board equipment 30, the radio rebroadcast equipment 32, the CCTV monitoring equipment 34, and the lighting equipment 36.

この場合、制御部４０は、図４に示したように、火災発報を検出した火災検出器１６ｉの両側に隣接する火災検出器１６ｉ−１，１６ｉ＋１を火災判別候補に設定しているが、発信機５６の操作による火災通報の検出については、車両事故等で発生した火災場所から利用者が避難する途中で、消火栓装置２０に設けている発信機５６を操作して火災通報する場合があることから、火災判別候補の設定による火災判別の制約は解除し、任意の発信機５６による火災通報の検出を判別して火災警報制御を行う。 In this case, the control unit 40, as shown in FIG. 4, to set the fire detector 16 i-1, 16 i + 1 adjacent to each side of the fire detector 16 i detects a fire alert in the fire discriminating candidate However, regarding the detection of a fire notification by operating the transmitter 56, the user notifies the fire by operating the transmitter 56 provided in the fire hydrant device 20 while the user is evacuating from a fire place caused by a vehicle accident or the like. Since there is a case, the fire discrimination restriction by setting the fire discrimination candidate is released, and the fire alarm control is performed by discriminating the detection of the fire notification by an arbitrary transmitter 56.

（火災検出器とポンプ起動操作手段に基づく火災制御）
また、ＰＲ型防災受信盤１０Ｂの制御部４０は、図１０に示すように、Ｒ型伝送部４２による１台目の火災検出器１６ｉによる火災発報の検出を判別した場合、火災発報を検出した火災検出器１６ｉの両側に隣接する火災検出器１６ｉ−１，１６ｉ＋１を火災判別候補に設定し、この状態で、Ｐ型伝送部４４により火災判別候補を含む区画１００に属する何れかの消火栓装置２０に設けたポンプ起動操作手段として機能する消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２によるポンプ起動の検出（Ｐ型信号回線１４ａを流れる回線電流の検出）を判別した場合、２台目の火災検出器による火災発報に相当すると判断することで、火災として扱い、警報部４５に指示して音声又はブザー等による警報と表示警報による火災警報を出力すると共に、設備連動による火災警報として、換気設備２８、警報表示板設備３０、ラジオ再放送設備３２、ＣＣＴＶ監視設備３４及び照明設備３６の全てを連動する制御を行う。 (Fire control based on fire detector and pump activation operation means)
Further, as shown in FIG. 10, the control unit 40 of the PR-type disaster prevention receiving board 10B determines that the fire detection is detected by the first fire detector 16i by the R-type transmission unit 42. fire detector 16 i-1, 16 i + 1 adjacent to each side of the detected fire detector 16 i set fire discrimination candidates, in this state, belong to the compartment 100 containing the fire discrimination candidates by P-type transmission unit 44 When determining the detection of pump activation (detection of the line current flowing through the P-type signal line 14a) by the fire hydrant valve opening / closing detection switch 60 or the pump activation switch 62 functioning as a pump activation operation means provided in any of the hydrant devices 20, By judging that it corresponds to a fire alarm by the second fire detector, treat it as a fire, instruct the alarm unit 45 to give a warning by voice or buzzer and a display alarm And outputs, as a fire alarm by equipment interlocking controls to interlock all ventilation 28, the alarm panel equipment 30, Radio rebroadcast equipment 32, CCTV monitoring facility 34 and the lighting equipment 36.

また、制御部４０は消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２によるポンプ起動の検出を判別すると、Ｐ型伝送部５２に指示して消火ポンプ設備２４に起動信号を出力する制御を行い、消火ポンプを起動させる。   In addition, when the control unit 40 determines the detection of pump start by the fire hydrant valve opening / closing detection switch 60 or the pump start switch 62, the control unit 40 instructs the P-type transmission unit 52 to output a start signal to the fire pump system 24, Start the pump.

なお、図１０の区画１００は消火栓装置２０を５台含むが、区画１００に設ける消火栓装置２０の台数は、Ｐ型信号回線１４ｂに接続可能な端末機器の最大数の範囲内で適宜に定めることを可能とする。   10 includes five fire hydrant devices 20, but the number of fire hydrant devices 20 provided in the partition 100 should be appropriately determined within the range of the maximum number of terminal devices connectable to the P-type signal line 14b. Is possible.

一方、ＰＲ型防災受信盤１０Ｂの制御部４０は、図１０に示すように、Ｒ型伝送部４２ｂによる区画１００に属する消火栓装置２０の何れかに設けた消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２によるポンプ起動の検出（Ｐ型信号回線１４ａを流れる回線電流の検出）を判別して予備警報制御を行った状態で、区画１００に対応した火災検出器１６ｉ−２〜１６ｉ＋２の何れかによる火災発報の検出を判別した場合、火災として扱い、警報部４５に指示して音声又はブザー等による警報と表示警報による火災警報を出力すると共に、設備連動による火災警報として、換気設備２８、警報表示板設備３０、ラジオ再放送設備３２、ＣＣＴＶ監視設備３４及び照明設備３６の全てを連動する制御を行う。 On the other hand, as shown in FIG. 10, the control unit 40 of the PR-type disaster prevention receiving panel 10B includes a fire hydrant valve opening / closing detection switch 60 or a pump activation switch provided in any of the fire hydrant devices 20 belonging to the section 100 by the R-type transmission unit 42b. One of the fire detectors 16 i-2 to 16 i + 2 corresponding to the section 100 in a state in which the detection of the pump activation by 62 (detection of the line current flowing through the P-type signal line 14a) is determined and the preliminary alarm control is performed. If it is determined that a fire alarm has been detected, the alarm unit 45 is instructed to output a fire alarm using a voice or buzzer and a display alarm, and a ventilation alarm 28, Control that interlocks all of the alarm display board equipment 30, the radio rebroadcasting equipment 32, the CCTV monitoring equipment 34, and the lighting equipment 36 is performed.

［ＰＲ型トンネル防災システムの監視制御］
図１１はＰＲ型防災受信盤による監視制御を示したフローチャートであり、図７〜図１０を参照して説明すると次のようになる。 [Monitoring control of PR type tunnel disaster prevention system]
FIG. 11 is a flowchart showing the monitoring control by the PR type disaster prevention receiving board, which will be described below with reference to FIGS.

図１１に示すように、ＰＲ型防災受信盤１０Ｂの制御部４０は、ステップＳ２１でＲ型伝送部４２による１台目の火災感知器１６の火災発報の検出を判別すると、Ｓ２２に進んで警報部４５から火災予備警報を出力させ、続いて、Ｓ２３でＰ型伝送部５２を介して設備の一部となるＣＣＴＶ監視設備３４及び照明設備３６を所定の状態に連動させる予備警報により注意を喚起する制御を行う。   As shown in FIG. 11, when the control unit 40 of the PR-type disaster prevention receiving board 10B determines that the fire alarm of the first fire detector 16 is detected by the R-type transmission unit 42 in step S21, the process proceeds to S22. A fire preliminary alarm is output from the alarm unit 45, and then, in S23, attention is paid by a preliminary alarm that links the CCTV monitoring equipment 34 and the lighting equipment 36 that are part of the equipment to a predetermined state via the P-type transmission unit 52. Controls to provoke.

次いで、制御部４０は、Ｓ２４に進み、図１０に示したように、火災発報を検出した火災検出器１６ｉの両側に隣接する火災検出器１６ｉ−１，１６ｉ＋１を火災判別候補に設定し、Ｒ型伝送部４２による火災判別候補に属する２台目の火災検出器１６ｉ−１，１６ｉ＋１の何れかによる火災発報の検出を判別するとＳ２５に進み、警報部４５に指示して火災警報を出力させ、次いでＳ２６で全設備の連動制御による火災警報を行う。その後、火災が鎮火してＳ２７で復旧を判別すると、ＰＲ型防災受信盤１０Ｂを復旧して処理を終了する。 Then, the control unit 40 proceeds to S24, as shown in FIG. 10, the fire detector 16 i-1, 16 i + 1 adjacent to each side of the fire detector 16 i detects a fire alert in the fire discriminating candidate If it is determined that the detection of the fire alarm by any of the second fire detectors 16 i-1 and 16 i + 1 belonging to the fire discrimination candidate by the R-type transmission unit 42 is discriminated, the process proceeds to S25 and the alarm unit 45 is instructed. The fire alarm is output, and then in S26, the fire alarm is performed by interlocking control of all facilities. Thereafter, when the fire is extinguished and restoration is determined in S27, the PR type disaster prevention receiving board 10B is restored and the process is terminated.

一方、制御部４０は、Ｓ２４で他の火災検出器の火災発報の検出がない場合はＳ２８，Ｓ２９の処理をループしており、Ｓ２８でＰ型伝送部４４による発信機５６の操作による火災通報の検出を判別すると、火災判別候補を考慮することなくＳ２５に進み、警報部４５に指示して火災警報を出力させ、次いでＳ２６で全設備の連動制御による火災警報を行う。   On the other hand, the control unit 40 loops the processing of S28 and S29 when no fire alarm is detected by another fire detector in S24, and the fire caused by the operation of the transmitter 56 by the P-type transmission unit 44 in S28. If the detection of the notification is determined, the process proceeds to S25 without considering the fire determination candidate, and the alarm unit 45 is instructed to output a fire alarm, and then in S26, the fire alarm is performed by the interlock control of all facilities.

また、制御部４０は、Ｓ２９でＰ型伝送部４４により、何れかの消火栓装置２０の消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２の操作によるポンプ起動の検出を判別すると、Ｓ３０でＰ型伝送部５２に指示してポンプ起動信号を消火ポンプ設備に出力して消火ポンプの運転を開始し、続いて、Ｓ３１に進み、図１０に示したように、火災発報した火災検出器１６ｉに対応した区画１００に属する何れかの消火栓装置２０の消火栓弁開閉検出スイッチ６０又はポンプ起動スイッチ６２の操作によるポンプ起動の検出を判別するとＳ２５に進み、警報部４５に指示して火災警報を出力させ、次いでＳ２６で全設備の連動制御による火災警報を行う。 Further, when the control unit 40 determines in S29 that the P-type transmission unit 44 detects the pump activation by operating the hydrant valve opening / closing detection switch 60 or the pump activation switch 62 of any of the hydrant devices 20, the P-type transmission is performed in S30. It instructs section 52 outputs a pump start signal to the fire extinguishing pump equipment starts the operation of the fire extinguishing pump, then, the process proceeds to S31, as shown in FIG. 10, the fire detector 16 i that fire alert If it is determined that the pump is activated by operating the hydrant valve opening / closing detection switch 60 or the pump activation switch 62 of any of the hydrant devices 20 belonging to the corresponding section 100, the process proceeds to S25, and the alarm unit 45 is instructed to output a fire alarm. Then, in S26, a fire alarm is performed by interlocking control of all facilities.

また、制御部４０は、Ｓ２１でＲ型伝送部４２による火災感知器１６の火災発報の検出を判別しない場合はＳ３２に進み、Ｐ型伝送部４４による発信機５６の操作による火災通報の検出を判別するとＳ３３に進み、Ｓ２２と同様に警報部４５から予備火災警報を出力させ、続いて、Ｓ３４に進み、Ｓ２３と同様に、Ｐ型伝送部５２を介して設備の一部となるＣＣＴＶ監視設備３４及び照明設備３６を所定の状態に連動させる予備警報により注意を喚起する制御を行う。   Further, when the control unit 40 does not determine whether the fire detector 16 detects the fire alarm by the R-type transmission unit 42 in S21, the control unit 40 proceeds to S32 and detects the fire notification by operating the transmitter 56 by the P-type transmission unit 44. If it is determined, the process proceeds to S33, where a preliminary fire alarm is output from the alarm unit 45 in the same manner as in S22.
