Description

本発明は、トンネル内に設置した通報装置や検知器等の端末機器を防災受信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 abnormalities in a tunnel by connecting terminal devices such as a notification device and a detector installed in the tunnel to a disaster prevention receiver.

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 such as motorways to protect people and vehicles from fire accidents that occur in the tunnels.

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知器、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、更にトンネル躯体やダクト内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 include fire detectors, manual notification devices, and emergency telephones for fire monitoring and reporting, fire extinguishing plug devices for extinguishing fires and preventing the spread of fire, and tunnel skeletons. In order to protect the inside of the duct from fire, water spray that sprinkles fire extinguishing water from the water spray head is installed, and a disaster prevention receiver is installed to monitor and control the terminal equipment of these emergency facilities to build a tunnel disaster prevention system. doing.

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知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属す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。 The tunnel disaster prevention system consisting of a disaster prevention receiver and terminal equipment is roughly divided into an R-type transmission system and a P-type direct delivery system. The R-type transmission method connects a terminal device such as a fire detector whose address is set to a transmission line, and enables individual management in which detection and control are performed for each terminal device by transmission control. In the P-type direct delivery method, a plurality of terminal devices belonging to the same section are connected to a signal line drawn out in a predetermined section unit according to the type of the terminal device, and detection and control are performed for each signal line.

ところで、P型直送方式のトンネル防災システムにあっては、手動通報装置、消火栓起動装置、ダクト温度検知器等の端末機器は、操作又は検知による信号出力部を無電圧a接点スイッチとして構成し、防災受信盤から引き出された信号回線に無電圧a接点スイッチ接続している。無電圧a接点スイッチは通常監視状態でオフしており、操作や検知動作によりオンして無電圧接点信号を出力する。 By the way, in the P-type direct delivery type tunnel disaster prevention system, terminal devices such as a manual notification device, a fire extinguisher activation device, and a duct temperature detector have a signal output unit for operation or detection configured as a non-voltage a contact switch. A non-voltage a contact switch is connected to the signal line drawn from the disaster prevention receiver. The non-voltage a-contact switch is normally turned off in the monitoring state, and is turned on by an operation or detection operation to output a non-voltage contact signal.

具体的には、防災受信盤に設けられた回線受信部で信号回線の一方にプルアップ抵抗を介して電源電圧を印加しており、無電圧a接点スイッチがオフした定常監視状態では、信号回線に消費電流は殆ど流れず、防災受信盤から見た信号回線間の電源電圧は略電源電圧に保たれている。無電圧a接点スイッチがオンすると信号回線に電流が流れ、防災受信盤から見た信号回線間の電圧は略零ボルトに低下し、防災受信盤の回線受信部は信号回線の消費電流の増加又は信号回線間の電圧低下を検出して端末機器の操作又は検知を示す受信信号を制御部に出力する。 Specifically, the power supply voltage is applied to one of the signal lines via a pull-up resistor at the line receiver provided in the disaster prevention receiver, and the signal line is in the steady monitoring state when the non-voltage a contact switch is turned off. Almost no current is consumed, and the power supply voltage between the signal lines seen from the disaster prevention receiver is kept at approximately the power supply voltage. When the non-voltage a contact switch is turned on, a current flows through the signal line, the voltage between the signal lines seen from the disaster prevention receiver drops to almost zero volts, and the line receiver of the disaster prevention receiver increases the current consumption of the signal line or Detects a voltage drop between signal lines and outputs a received signal indicating the operation or detection of the terminal device to the control unit.

例えば手動通報装置からの火災通報信号であれば、防災受信盤は、火災表示、端末側の応答ランプの点灯制御、手動通報区画表示といった制御動作を行うと共に、遠方監視制御設備、テレビ監視設備、可変式道路情報板設備、トンネル換気設備、照明設備等の外部設備に火災通報信号を送信して所定の対処制御を行わせるようにしている。 For example, in the case of a fire report signal from a manual report device, the disaster prevention receiver performs control operations such as fire display, lighting control of the response lamp on the terminal side, and manual report section display, as well as remote monitoring control equipment, TV monitoring equipment, and so on. A fire alarm signal is transmitted to external equipment such as variable road information board equipment, tunnel ventilation equipment, and lighting equipment so that predetermined countermeasure control can be performed.

また、消火栓装置に設けられた消火栓弁開閉検出スイッチ等の消火栓起動装置からの消火栓起動信号であれば、防災受信盤は、消火ポンプ設備にポンプ起動信号を送信して遠隔的に消火ポンプ設備を起動運転させるようにしている。 In addition, if it is a fire hydrant start signal from a fire hydrant starter such as a fire hydrant valve open / close detection switch provided in the fire hydrant device, the disaster prevention receiver sends a pump start signal to the fire hydrant pump equipment to remotely operate the fire hydrant pump equipment. I am trying to start the operation.

特開2002−246962号公報Japanese Unexamined Patent Publication No. 2002-246962 特開平11−128381号公報Japanese Unexamined Patent Publication No. 11-128381

このような従来のP型直送方式のトンネル防災システムにあっては、端末機器を接続している信号回線(外線ケーブル)の経年劣化等により絶縁低下が進み、端末機器を接続している信号回線に通常監視状態で想定される以上の電流が流れ、防災受信盤は端末機器の操作又は検知動作による信号受信と判断して警報動作を行うと共に、遠方監視制御設備、テレビ監視設備、可変式道路情報板設備、トンネル換気設備、照明設備等の他設備を連動し、トンネルを通行止めにすることが度々生じている。 In such a conventional P-type direct delivery type tunnel disaster prevention system, the insulation deteriorates due to aged deterioration of the signal line (outside line cable) connecting the terminal equipment, and the signal line connecting the terminal equipment. More current than expected in the normal monitoring state flows, and the disaster prevention receiver determines that the signal is received by the operation or detection operation of the terminal equipment and performs an alarm operation, as well as remote monitoring control equipment, TV monitoring equipment, and variable road. Information board equipment, tunnel ventilation equipment, lighting equipment, and other other equipment are often linked to block traffic in tunnels.

この問題を解決するため、防災受信盤とは別の筐体に電流監視装置を設け、無電圧a接点スイッチを設けた端末機器を接続した信号回線に流れる電流を、例えば1日1回というように定周期で測定して記録し、更に、測定した電流が所定の閾値範囲を外れた場合に信号回線の電流値異常を判定して警報するようにしている。 In order to solve this problem, a current monitoring device is provided in a housing separate from the disaster prevention receiver, and the current flowing through the signal line connected to the terminal device provided with the non-voltage a contact switch is, for example, once a day. It is measured and recorded at regular intervals, and when the measured current deviates from a predetermined threshold range, an abnormality in the current value of the signal line is determined and an alarm is given.

ところで、従来の防災受信盤にあっては、信号回線が引き出された回線受信部が故障した場合には、手動通報装置からの火災通報信号や消火栓起動装置からの消火栓起動信号が受信されず、火災警報機能や消火ポンプ設備の遠隔起動機能が失われ、正常に動作できない問題がある。 By the way, in the conventional disaster prevention receiver, when the line receiver from which the signal line is pulled out breaks down, the fire alarm signal from the manual alarm device and the fire hydrant activation signal from the fire hydrant activation device are not received. There is a problem that the fire alarm function and the remote start function of the fire extinguishing pump equipment are lost and cannot operate normally.

また、従来は防災受信盤に対し電流監視装置を別の筐体に設けているため、防災受信盤から火災情報や障害情報等を電流測定装置に送って測定履歴と共に記憶させる伝送機能と処理機能が必要となり、設備構成と処理が複雑になる問題もある。 In addition, since the current monitoring device is conventionally provided in a separate housing from the disaster prevention receiver, the transmission function and processing function that send fire information, failure information, etc. from the disaster prevention receiver to the current measurement device and store it together with the measurement history. There is also a problem that the equipment configuration and processing become complicated.

本発明は、防災受信盤に電流監視装置の機能を一体化して設備構成及び処理を簡略化すると共に、手動通報信号や消火栓起動信号を受信する受信回路部が故障しても、防災受信盤に設けられた電流監視機能を利用したリカバリにより防災監視機能が失われないように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。 The present invention simplifies the equipment configuration and processing by integrating the functions of the current monitoring device into the disaster prevention receiving board, and even if the receiving circuit unit that receives the manual notification signal or the fire extinguisher start signal fails, the disaster prevention receiving board can be used. The purpose is to provide a tunnel disaster prevention system that prevents the disaster prevention monitoring function from being lost by recovery using the provided current monitoring function.

(基本的な効果)
本発明は、防災受信盤からトンネル内に引き出された複数の信号回線毎に接続された火災信号を出力する手動通報装置を含む複数の端末機器と、防災受信盤に設けられ、回線受信部により信号回線から前記火災信号を受信して火災警報を出力する監視制御部と、防災受信盤に設けられ、複数の信号回線に流れる電流値を所定の測定周期毎に測定して測定履歴として記憶し、測定した電流値が所定の閾値範囲を外れた場合に電流値異常を判定して電流値異常警報を出力すると共に測定履歴に含めて記憶する電流監視部とを備えたトンネル防災システムに於いて、監視制御部は、回線受信部の故障を検出した場合に、電流監視部に指示して故障が検出された回線受信部に接続された信号回線に流れる電流値を測定させ、測定された電流値が所定の火災閾値以上の場合に火災を判定して火災警報を出力させるようにしたため、火災信号を受信する回線受信部が故障しても、電流監視部が故障した回線受信部から信号回線に流れる電流値を測定しており、測定された電流値が火災閾値以上に増加した場合に火災を判定して火災警報を出力させることができ、回線受信部の故障を電流監視部により完全にリカバリして正常な火災監視を継続させることが可能となり、トンネル内の防災監視の信頼性を高めることかできる。
(Basic effect)
The present invention is provided in a plurality of terminal devices including a manual notification device that outputs a fire signal connected to each of a plurality of signal lines drawn out from the disaster prevention receiving board into the tunnel, and the disaster prevention receiving board by the line receiving unit. A monitoring control unit that receives the fire signal from the signal line and outputs a fire alarm, and a disaster prevention receiver are provided to measure the current value flowing through multiple signal lines at predetermined measurement cycles and store it as a measurement history. In a tunnel disaster prevention system equipped with a current monitoring unit that determines a current value abnormality when the measured current value deviates from a predetermined threshold range, outputs a current value abnormality alarm, and stores the measured current value in the measurement history. When the monitoring control unit detects a failure in the line receiving unit, it instructs the current monitoring unit to measure the current value flowing through the signal line connected to the line receiving unit in which the failure is detected, and the measured current. Since the fire is judged and a fire alarm is output when the value is equal to or higher than the predetermined fire threshold, even if the line receiving unit that receives the fire signal fails, the current monitoring unit fails the signal line from the line receiving unit. The current value flowing through the system is measured, and when the measured current value increases above the fire threshold, a fire can be determined and a fire alarm can be output. It is possible to recover and continue normal fire monitoring, and it is possible to improve the reliability of disaster prevention monitoring in the tunnel.

また、防災受信盤と一体に電流監視部が設けられたため、電流監視装置を別筐体に設けていた場合に比べ、設備構成及び処理が簡単となり、設置スペースも低減できる。 Further, since the current monitoring unit is provided integrally with the disaster prevention receiver, the equipment configuration and processing can be simplified and the installation space can be reduced as compared with the case where the current monitoring device is provided in a separate housing.

(消火栓起動信号の回線受信部故障に対する効果)
また、端末機器は、消火栓弁開閉レバーの開操作又はポンプ起動スイッチの起動操作により消火栓起動信号を出力する検出スイッチであり、監視制御部は、回線受信部により信号回線から消火栓起動信号を受信した場合に、消火ポンプ設備にポンプ起動信号を送信して運転を開始させ、一方、消火栓起動信号を受信する回線受信部の故障を検出した場合に、電流監視部に指示して故障が検出された回線受信部に接続された信号回線に流れる電流値を測定させ、測定された電流値が所定の起動閾値以上の場合に消火栓起動信号の受信を判定して消火ポンプ設備にポンプ起動信号を送信させるようにしたため、消火栓起動信号を受信する回線受信部が故障しても、電流監視部が故障した回線受信部から信号回線に流れる電流値を測定しており、測定された電流値が起動閾値以上に増加した場合に消火栓起動を判定してポンプ起動信号を送信させることができ、回線受信部の故障を電流監視部により完全にリカバリして正常な消火ポンプ設備を遠隔起動させる機能を継続して維持させることが可能となり、トンネル内の防災監視の信頼性を高めることかできる。
(Effect of fire hydrant start signal line receiver failure)
The terminal device is a detection switch that outputs a fire hydrant start signal by opening the fire hydrant valve open / close lever or starting the pump start switch, and the monitoring control unit receives the fire hydrant start signal from the signal line by the line receiver. In this case, when a failure of the line receiver that receives the fire hydrant start signal is detected by sending a pump start signal to the fire hydrant pump equipment to start the operation, the failure is detected by instructing the current monitoring unit. The current value flowing through the signal line connected to the line receiver is measured, and when the measured current value is equal to or higher than the predetermined start threshold, the reception of the fire hydrant start signal is judged and the fire hydrant pump equipment is made to transmit the pump start signal. Therefore, even if the line receiver that receives the fire hydrant start signal fails, the current monitor measures the current value that flows from the failed line receiver to the signal line, and the measured current value is equal to or greater than the start threshold. It is possible to judge the start of the fire hydrant and send a pump start signal when the number increases to, and the current monitoring unit completely recovers the failure of the line receiver and continues the function to remotely start the normal fire hydrant equipment. It can be maintained and the reliability of disaster prevention monitoring in the tunnel can be improved.

(電流測定周期を短縮による効果)
また、監視制御部は、回線受信部の故障を検出した場合に、電流監視部に指示して、測定周期をそれより短い所定の測定周期に変更して故障が検出された回線受信部に接続された信号回線に流れる電流値を測定させるようにしたため、信号回線の絶縁劣化等により電流値異常の測定は、例えば1日1回といった定周期測定であるが、回線受信部の故障が検出された場合には、火災監視に必要な例えば1分に1回といった短い火災監視周期に変更して電流値測定が行われ、回線受信部が正常に動作している場合と同等な火災監視を可能とする。
(Effect of shortening the current measurement cycle)
Further, when the monitoring control unit detects a failure of the line receiving unit, it instructs the current monitoring unit to change the measurement cycle to a predetermined measurement cycle shorter than that and connects to the line receiving unit in which the failure is detected. Since the current value flowing through the signal line is measured, the measurement of the current value abnormality due to the insulation deterioration of the signal line is a fixed cycle measurement such as once a day, but a failure of the line receiver is detected. In that case, the current value is measured by changing to a short fire monitoring cycle, for example, once a minute, which is necessary for fire monitoring, and fire monitoring equivalent to that when the line receiver is operating normally is possible. And.

(表示パネルによる回線受信部故障と故障リカバリの表示の効果)
また、防災受信盤の筐体前面に表示パネルが配置され、電流監視部は、回線受信部の故障が検出された場合に、表示パネルに設けられた回線受信部故障灯を作動して表示させ、電流監視部により故障が検出された回線受信部に接続された信号回線に流れる電流値を測定して火災を監視する処理が開始された場合に、表示パネルに設けられた回線受信部故障リカバリ灯を作動して表示させるようにしたため、回線受信部が故障すると防災受信盤の前面に配置された表示パネルの回線受信部故障灯が点灯又は点滅することで、回線受信部の故障を確認して修理等の対応を適切にとることが可能となる。
(Effect of line receiver failure and failure recovery display on the display panel)
In addition, a display panel is arranged on the front of the housing of the disaster prevention receiver, and when a failure of the line receiver is detected, the current monitoring unit activates the line receiver failure light provided on the display panel to display it. , Line receiver failure recovery provided on the display panel when the process of monitoring a fire by measuring the current value flowing through the signal line connected to the line receiver where the failure was detected by the current monitor is started. Since the light is activated to display, if the line receiver fails, the line receiver failure light on the display panel located in front of the disaster prevention receiver lights up or blinks to confirm the failure of the line receiver. It will be possible to take appropriate measures such as repairs.

また、電流監視部が故障した回線受信部の機能がリカバリされて正常に火災監視が行われていることが、表示パネルに設けられた回線受信部故障リカバリ灯の点灯で確認でき、回線受信部の故障に対し時間的な余裕をもって適切に対処可能となる。 In addition, it can be confirmed by lighting the line receiver failure recovery light provided on the display panel that the function of the line receiver whose current monitoring unit has failed has been recovered and the fire is being monitored normally. It becomes possible to appropriately deal with the failure of the above with a time margin.

(筐体内モニタ装置による効果)
また、防災受信盤の筐体内にモニタ装置が配置され、電流監視部は、所定の測定履歴読出し操作を検出した場合に、測定履歴を読み出してモニタ装置に画面表示させるようにしたため、信号回線の絶縁劣化等を監視するために測定された電流値の測定履歴をモニタ装置の画面による見ることで、信号回線の劣化状態を適切に把握可能となり、また、回線受信部が故障した状態でも測定した電流値の測定履歴が生成されていることから、火災信号や消火栓起動信号の履歴も併せてモニタ装置で見ることを可能とする。
(Effect of monitoring device in the housing)
In addition, a monitor device is arranged in the housing of the disaster prevention receiver, and when the current monitoring unit detects a predetermined measurement history reading operation, the measurement history is read out and displayed on the screen of the monitoring device. By viewing the measurement history of the current value measured to monitor insulation deterioration etc. on the screen of the monitor device, it is possible to appropriately grasp the deterioration state of the signal line, and it is also measured even when the line receiver is out of order. Since the measurement history of the current value is generated, the history of the fire signal and the fire extinguisher start signal can also be viewed on the monitor device.

(メインモニタ装置とサブモニタ装置による表示の効果)
また、防災受信盤の筐体前面に配置されたメインモニタ装置と、防災受信盤の筐体内に配置されたサブモニタ装置とが設けられ、電流監視部は、所定の測定履歴読出し操作を検出した場合に、測定履歴を読み出してサブモニタ装置に画面表示させ、回線受信部の故障が検出された場合に、回線受信部故障の発生をメインモニタ装置に画面表示させ、故障が検出された回線受信部に接続された信号回線に流れる電流値を測定して火災を監視する処理が開始された場合に、回線受信部故障のリカバリをメインモニタ装置に画面表示させるようにしたため、回線受信部が故障すると防災受信盤の前面に配置されたメインモニタ装置に回線受信部の故障が画面表示されるので、これを確認して修理等の対応を適切にとることが可能となる。
(Effect of display by main monitor device and sub monitor device)
Further, when a main monitor device arranged in front of the housing of the disaster prevention receiving panel and a sub monitoring device arranged in the housing of the disaster prevention receiving panel are provided, and the current monitoring unit detects a predetermined measurement history reading operation. In addition, the measurement history is read out and displayed on the screen of the sub monitor device, and when a failure of the line receiver is detected, the occurrence of the line receiver failure is displayed on the screen of the main monitor device, and the line receiver where the failure is detected is displayed. When the process of monitoring the fire by measuring the current value flowing through the connected signal line is started, the recovery of the line receiver failure is displayed on the screen on the main monitor device, so if the line receiver fails, disaster prevention will occur. Since the failure of the line receiving unit is displayed on the screen on the main monitor device arranged in front of the receiving panel, it is possible to confirm this and take appropriate measures such as repair.

また、電流監視部が故障した回線受信部の機能がリカバリされて正常に火災監視が行われていることが、メインモニタ装置に画面表示され、これを見ることで回線受信部の故障に対し時間的な余裕をもって適切に対処可能となる。 In addition, the main monitor device displays on the screen that the function of the line receiving unit in which the current monitoring unit has failed has been recovered and fire monitoring is being performed normally. It will be possible to deal with it appropriately with a reasonable margin.

更に、信号回線の絶縁劣化等を監視するために測定された電流値の測定履歴をサブモニタ装置の画面により見ることで、信号回線の劣化状態を適切に把握可能となり、また、回線受信部が故障した状態でも測定した電流値の測定履歴が生成されていることから、火災信号や消火栓起動信号の履歴も併せてサブモニタ装置で見ることを可能とする。 Furthermore, by viewing the measurement history of the current value measured to monitor the insulation deterioration of the signal line on the screen of the sub monitor device, it is possible to appropriately grasp the deterioration state of the signal line, and the line receiver fails. Since the measurement history of the measured current value is generated even in this state, the history of the fire signal and the fire hydrant start signal can also be viewed on the sub monitor device.

(メインモニタ装置の火災表示による効果)
また、監視制御部は火災を判定した場合にメインモニタ装置を含む筐体面の機器により火災発生を表示させるようにしたたた、メインモニタ装置の画面を使用した火災表示や火災代表灯による火災表示により、火災警報を確実に報知可能とする。
(Effect of fire display on main monitor device)
In addition, when a fire is determined, the monitoring control unit displays the fire occurrence by the equipment on the housing surface including the main monitor device, and the fire display using the screen of the main monitor device and the fire display by the fire representative light This makes it possible to reliably notify the fire alarm.

(サブモニタ装置の火災表示による効果)
また、監視制御部は、故障が検出された回線受信部に接続された信号回線に流れる電流値を測定して火災を判定した場合に、サブモニタ装置に、火災を判定した信号回線、時刻、電流測定値の少なくとも何れかを含む火災詳細情報を表示させるようにしたため、回線受信部の故障を電流監視部によりリカバリして火災が判定された場合の状況がサブモニタ装置に表示された火災詳細情報から分かり、回線受信部の故障に対し適切に対応可能とする。
(Effect of fire display on sub monitor device)
Further, when the monitoring control unit measures the current value flowing through the signal line connected to the line receiving unit in which the failure is detected and determines a fire, the sub-monitor device is notified of the signal line, the time, and the current for which the fire is determined. Since detailed fire information including at least one of the measured values is displayed, the situation when a fire is determined by recovering the failure of the line receiver by the current monitoring unit is displayed from the detailed fire information displayed on the sub monitor device. Understand that it is possible to respond appropriately to the failure of the line receiver.

(サブモニタ装置の消火栓起動信号の受信表示による効果)
また、監視制御部は、故障が検出された回線受信部に接続された信号回線に流れる電流値を測定して消火栓起動信号の受信を判定した場合、サブモニタ装置に、消火栓起動信号受信を判定した信号回線、時刻、電流測定値の少なくとも何れかを含む詳細情報を表示させるようにしたため、回線受信部の故障を電流監視部によりリカバリして消火栓起動信号の受信が判定された場合の状況がサブモニタ装置に表示された詳細情報から分かり、回線受信部の故障に対し適切に対応可能とする。
(Effect of receiving and displaying the fire hydrant start signal of the sub monitor device)
Further, when the monitoring control unit measures the current value flowing through the signal line connected to the line receiving unit in which the failure is detected and determines the reception of the fire extinguisher activation signal, the sub monitor device determines the reception of the fire extinguisher activation signal. Since detailed information including at least one of the signal line, time, and current measurement value is displayed, the situation when the failure of the line receiver is recovered by the current monitor and the reception of the fire extinguisher start signal is determined is sub-monitored. It can be understood from the detailed information displayed on the device, and it is possible to appropriately respond to the failure of the line receiver.

Since the measured values of the other line numbers are within the range of the upper limit value and the lower limit value, it is judged to be normal by the display of "OK".

電流監視部58は、1日1回の測定周期により測定された電流値の測定履歴を記憶しており、測定記録選択ボタン75の操作で、記憶している履歴情報に基づき測定履歴詳細情報83を画面表示するが、監視制御部56の指示に基づき故障した回線受信部60のリカバリ制御を行っている場合は、例えば1分に1回の短い周期で信号回線の電流値を測定しており、このリカバリ制御における電流値も測定履歴として記憶させている。 The current monitoring unit 58 stores the measurement history of the current value measured by the measurement cycle once a day, and by operating the measurement record selection button 75, the measurement history detailed information 83 is based on the stored history information. Is displayed on the screen, but when the recovery control of the failed line receiving unit 60 is performed based on the instruction of the monitoring control unit 56, the current value of the signal line is measured at a short cycle of once per minute, for example. , The current value in this recovery control is also stored as a measurement history.

このため図7のように測定記録画面72を表示させた場合には、回線受信部60の故障に対するリカバリ制御で測定された電流値の測定履歴も見ることができる。 Therefore, when the measurement recording screen 72 is displayed as shown in FIG. 7, the measurement history of the current value measured by the recovery control for the failure of the line receiving unit 60 can also be seen.
