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 in order 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, emergency telephones for fire monitoring and reporting, fire hydrant 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 tunnel disaster prevention system is constructed by installing a disaster prevention receiver that monitors and controls the terminal equipment of these emergency facilities. are 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 the disaster prevention receiver and the terminal equipment is roughly classified into the R type transmission system and the 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 hydrant starter, 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、防災受信盤側から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 from the disaster prevention receiver side via a pull-up resistor, and in the steady monitoring state when the non-voltage a contact switch is turned off, most of the current consumption flows through the signal line. However, 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 disaster prevention receiver increases the current consumption of the signal line or between the signal lines. Detects a voltage drop 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、消火ポンプ起動信号の出力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, manual report section display, and output of a fire extinguishing pump start signal, and also performs remote monitoring. A fire alarm signal is sent to external equipment such as control equipment, TV monitoring equipment, variable road information board equipment, tunnel ventilation equipment, and lighting equipment so that predetermined countermeasure control can be performed.

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 tunnel disaster prevention system, the insulation deteriorates due to aged deterioration of the signal line (outside line cable) connecting the terminal device, and the signal line connecting the terminal device. 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 close 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、防災受信盤で火災通報信号を受信して火災警報が出力された場合や、信号回線の障害が検出されて障害警報が出力された場合には、その後の調査作業の段階で、火災信号が受信された火災回線や障害が検出された障害回線について、電流監視装置で測定された測定履歴を表示させ、火災回線や障害回線がどのような状態にあったかを調べる場合がある。 By the way, if the disaster prevention receiver receives a fire report signal and outputs a fire alarm, or if a signal line failure is detected and a failure alarm is output, the fire signal will be displayed at the subsequent investigation stage. The measurement history measured by the current monitoring device may be displayed for the fire line in which the fire line is received or the failure line in which the failure is detected, and the state of the fire line or the failure line may be investigated.

しかしながら、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。 However, 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.

また、従来の防災受信盤にあっては、筐体前面に配置されたグラフィックパネルに、トンネル系統図を配置し、系統図の中に、手動通報装置及び消火栓起動装置に分けて回線表示灯を配列しており、手動通報装置から火災通報信号を受信して火災警報を出力した場合に、手動通報装置に対応した回線表示灯を点灯して火災発生区画を表示させており、また、消火栓起動装置からポンプ起動信号を受信した場合に、消火栓起動装置に対応した回線表示灯を点灯して消火栓が起動された区画を表示させている。 In addition, in the conventional disaster prevention receiver, a tunnel system diagram is placed on the graphic panel arranged on the front of the housing, and the line indicator lights are divided into the manual notification device and the fire hydrant activation device in the system diagram. They are arranged, and when a fire notification signal is received from the manual notification device and a fire alarm is output, the line indicator lamp corresponding to the manual notification device is turned on to display the fire hydrant section, and the fire hydrant is activated. When a pump start signal is received from the device, the line indicator light corresponding to the fire hydrant starter is turned on to display the section where the fire hydrant is started.

また、防災受信盤は信号回線による火災監視以外に信号回線の断線監視を行っており、筐体の前面パネルで断線障害の代表表示を行うようにしている。 In addition to the fire monitoring by the signal line, the disaster prevention receiver also monitors the disconnection of the signal line, and the front panel of the housing is used to display the representative of the disconnection failure.

しかしながら、断線障害が起きている信号回線を調べるには手間と時間がかかり、どの区画の信号回線にトラブルが起きているかを簡単に確認できない問題がある。 However, it takes time and effort to check the signal line in which the disconnection failure occurs, and there is a problem that it is not possible to easily confirm which section of the signal line has the trouble.

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、信号回線に対応して設けられている回線表示灯を利用して、火災以外に断線障害、電流値異常又は電流値異常が起きている信号回線を容易に把握して必要な対処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。 In the present invention, the functions of the current monitoring device are integrated with the disaster prevention receiver to simplify the equipment configuration and processing, and the line indicator lamp provided corresponding to the signal line is used to cause a disconnection failure other than a fire. It is an object of the present invention to provide a tunnel disaster prevention system capable of easily grasping a signal line in which an abnormal current value or an abnormal current value is occurring and taking necessary measures.

[トンネル防災システムの概要]
図1はトンネル防災システムの概要を示した説明図である。図1に示すように、自動車専用道路のトンネルとして、上り線トンネル1aと下り線トンネル1bが構築され、上り線トンネル1aと下り線トンネル1bは避難連絡坑2でつながっている。
[Overview of tunnel disaster prevention system]
FIG. 1 is an explanatory diagram showing an outline of a tunnel disaster prevention system. As shown in FIG. 1, an up line tunnel 1a and a down line tunnel 1b are constructed as a tunnel for a motorway, and the up line tunnel 1a and the down line tunnel 1b are connected by an evacuation connecting pit 2.

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監視員通路の壁面に沿って例えば50メートル間隔で消火栓装置18が設置されている。 Inside the up line tunnel 1a and the down line tunnel 1b, fire hydrant devices 18 are installed along the wall surface of the observer passage in the longitudinal direction of the tunnel, for example, at intervals of 50 meters.

消火栓装置18は消火栓扉内にノズル付きホースを収納しており、火災時には消火栓扉を開いてノズル付きホースを引き出し、消火栓弁開閉レバーを開操作すると消火用水が放水され、また、消火栓弁開閉検出スイッチ14がオンして消火ポンプを起動させる。 The fire hydrant device 18 houses a hose with a nozzle inside the fire hydrant door. In the event of a fire, the fire hydrant door is opened to pull out the hose with a nozzle, and when the fire hydrant valve open / close lever is opened, fire hydrant water is discharged and the fire hydrant valve open / close detection is detected. The switch 14 is turned on to start the fire extinguishing pump.

また、消火栓装置18には通報装置扉を設けており、通報装置扉には手動通報装置(発信機)16が設けられている。このように消火栓装置18には、消火栓弁開閉検出スイッチ14、及び手動通報装置16が端末機器として設けられており、それぞれ接点手段として機能する無電圧a接点スイッチのオンにより、消火栓起動信号及び火災通報信号が出力される。 Further, the fire hydrant device 18 is provided with a notification device door, and the notification device door is provided with a manual notification device (transmitter) 16. As described above, the fire hydrant device 18 is provided with the fire hydrant valve open / close detection switch 14 and the manual notification device 16 as terminal devices, and when the non-voltage a contact switch functioning as the contact means is turned on, the fire hydrant start signal and the fire are generated. A notification signal is output.

なお、消火栓装置18には消防隊が使用するポンプ起動スイッチが設けられているが、消火栓弁開閉検出スイッチ14と同じポンプ起動信号を出力するシステム的には同一のスイッチであることから、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)14として説明する。また、手動通報装置16は、消火栓装置18以外に、非常電話ボックス内にも設置しているが、以下の説明では、消火栓装置18に設けた手動通報装置を代表として説明する。 The fire hydrant device 18 is provided with a pump start switch used by the fire brigade, but since it is the same switch in terms of the system that outputs the same pump start signal as the fire hydrant valve open / close detection switch 14, the following A fire hydrant valve open / close detection switch (including a pump start switch) 14 will be described. Further, the manual notification device 16 is installed in the emergency telephone box in addition to the fire hydrant device 18, but in the following description, the manual notification device provided in the fire hydrant device 18 will be described as a representative.

トンネル非常設備として、消火栓装置18以外に、火災検知器、自動弁装置、ダクト内温度検知器等が設けられているが、図示を省略している。 In addition to the fire hydrant device 18, a fire detector, an automatic valve device, a temperature detector in a duct, and the like are provided as tunnel emergency equipment, but the illustration is omitted.

火災検知器はトンネル長手方向の壁面に沿って例えば25メートル又は50メートル間隔で設置され、左右25メートル又は50メートルとなる両側に監視エリアを設定し、火災による炎を検出して火災発報する。 Fire detectors are installed along the wall surface in the longitudinal direction of the tunnel, for example, at intervals of 25 meters or 50 meters, and monitoring areas are set on both sides, which are 25 meters or 50 meters on the left and right, to detect the flame caused by the fire and notify the fire. ..

自動弁装置は水噴霧設備を構成しており、作動用電動弁の遠隔開制御により主弁を開駆動し、トンネル壁面の上部の長手方向に設置した複数の水噴霧ヘッドから消火用水を放水してトンネル躯体を火災から防護する。 The automatic valve device constitutes a water spray facility, and the main valve is opened and driven by remote opening control of the electric valve for operation, and fire extinguishing water is discharged from multiple water spray heads installed in the longitudinal direction at the top of the tunnel wall surface. Protect the tunnel frame from fire.

ダクト内温度検知器は、トンネル長手方向の監視員通路の内部の配管やケーブルを敷設したダクトに配置されており、ケーブル火災等によるダクト内の温度上昇を検出し、接点手段として機能する無電圧a接点スイッチのオンにより温度検知信号を出力する。 The temperature detector in the duct is placed in the duct where the pipes and cables are laid inside the observer passage in the longitudinal direction of the tunnel, and detects the temperature rise in the duct due to a cable fire or the like, and functions as a contact means. A temperature detection signal is output when the a-contact switch is turned on.

図7は予兆閾値範囲の設定による電流値異常の予兆判定を示したグラフ図である。図7は例えば現在日(1日)からそれ以前の18日前までの定周期測定で得られた測定履歴の電流値の日変化を示している。このような電流値の測定履歴に対し、電流値異常を判定するための下限値Ith1と上限値Ith4が設定され、また、電流値異常を判定する閾値範囲Ith1〜Ith4の範囲内に、電流値異常の予兆を判定するための予兆下限値Ith2と予兆上限値Ith3が設定されている。
(Predictive judgment of current value abnormality by setting the predictive threshold range)
FIG. 7 is a graph showing a sign determination of a current value abnormality by setting a sign threshold range. FIG. 7 shows, for example, the diurnal change of the current value of the measurement history obtained by the fixed cycle measurement from the current day (1 day) to 18 days before that. A lower limit value Is1 and an upper limit value Is4 for determining a current value abnormality are set for such a current value measurement history, and a current value is within the range of the threshold range Is1 to Is4 for determining a current value abnormality. A sign lower limit value Is2 and a sign upper limit value Is3 for determining a sign of abnormality are set.

電流監視部58は、図7に示すように、電流値異常を判定する閾値範囲Ith1〜Ith4内に、それより狭い予兆閾値範囲Ith2〜Ith3を設定し、測定された電流値Iiが予兆閾値範囲Ith2〜Ith3を外れた場合、即ち、
Ith2≧Ii>Ith1又はIth4>Ii≧Ith3
となった場合に、電流値異常の予兆を判定して予兆警報を出力させる制御を行う。
As shown in FIG. 7, the current monitoring unit 58 sets a narrower predictive threshold range Is2 to Is3 within the threshold range Is1 to Is4 for determining the current value abnormality, and the measured current value Ii is the predictive threshold range. When it deviates from Is2 to Is3, that is,
Is2 ≧ Ii> Is1 or Is4> Ii ≧ Is3
When becomes, the control is performed to determine the sign of the current value abnormality and output the sign alarm.

図7にあっては、現在日(1日目)の定周期測定により測定された電流値Iiは予兆上限Ith3に達しており、このため電流監視部58は測定された電流値について、電流値異常の予兆を判定して予兆警報を出力させる。 In FIG. 7, the current value Ii measured by the fixed-period measurement of the current day (first day) has reached the upper limit of the sign Is3. Therefore, the current monitoring unit 58 has the current value of the measured current value. The sign of abnormality is judged and a sign alarm is output.

また、電流監視部58は、定周期測定、自動測定又は手動測定において電流値異常の予兆が判定された場合、図5に示した表示パネル50の中の手動通報電流値異常予兆灯130又は消火栓電流値異常予兆灯134を黄色点灯させて代表表示させる制御を行う。 Further, when the current value monitoring unit 58 determines a sign of a current value abnormality in the constant cycle measurement, automatic measurement, or manual measurement, the manual notification current value abnormality sign lamp 130 or the fire hydrant in the display panel 50 shown in FIG. Control is performed so that the current value abnormality sign lamp 134 is lit in yellow to display a representative display.

(平均電流との差による電流値異常の予兆判定)
図8は平均電流との差による電流値異常の予兆判定を示したグラフ図である。図8に示すように、電流監視部58は、測定履歴から過去の平均電流値Iaを求め、現在日(1日目)の定周期測定により測定された電流値Iiが電流値異常を判定する閾値範囲Ith1〜Ith4の範囲内にあることを条件に、測定された電流値Iiと平均電流値Iaとの差ΔIが所定の予兆閾値ΔIthを超えた場合に、電流値異常の予兆を判定して予兆警報を出力させる制御を行う。
(Determination of sign of current value abnormality due to difference from average current)
FIG. 8 is a graph showing a sign determination of a current value abnormality due to a difference from the average current. As shown in FIG. 8, the current monitoring unit 58 obtains the past average current value Ia from the measurement history, and the current value Ii measured by the fixed cycle measurement of the current day (first day) determines the current value abnormality. When the difference ΔI between the measured current value Ii and the average current value Ia exceeds a predetermined predictive threshold ΔIth on condition that the current value is within the threshold range Is1 to Is4, the sign of the current value abnormality is determined. Controls to output a sign alarm.

図8にあっては、現在日(1日目)の定周期測定により測定された電流値Iiと平均電流値Iaとの差ΔIが予兆閾値ΔIth以上となっており、このため電流監視部58は測定された電流値について、電流値異常の予兆を判定して予兆警報を出力させる。 In FIG. 8, the difference ΔI between the current value Ii and the average current value Ia measured by the constant cycle measurement of the current day (first day) is equal to or greater than the predictive threshold ΔIth. Therefore, the current monitoring unit 58 Determines the sign of abnormal current value for the measured current value and outputs a sign alarm.

(前回測定の電流値との差による電流値異常の予兆判定)
図9は前回測定の電流値との差による電流値異常の予兆判定を示したグラフ図である。図9に示すように、電流監視部58は、現在日(1日目)の定周期測定により測定された電流値Iiが電流値異常を判定する閾値範囲Ith1〜Ith4の範囲内にあることを条件に、前回測定された電流値Ii−1との差ΔIが所定の予兆閾値ΔIthを超えた場合に、電流値異常の予兆を判定して予兆警報を出力させる制御を行う。ここで、電流監視部58により求める今回測定された電流値Iiと前回測定された電流値Ii−1との差ΔIは、電流値の変化率を示しており、これは電流値の変化率が所定の閾値以上となった場合に電流値以上の予兆を判定して警報することを意味する。
(Determination of sign of current value abnormality due to difference from the current value measured last time)
FIG. 9 is a graph showing a sign determination of a current value abnormality due to a difference from the current value measured in the previous measurement. As shown in FIG. 9, the current monitoring unit 58 determines that the current value Ii measured by the fixed-period measurement of the current day (first day) is within the threshold range Is1 to Is4 for determining the current value abnormality. As a condition, when the difference ΔI from the previously measured current value Ii-1 exceeds a predetermined predictive threshold value ΔIth, the sign of the current value abnormality is determined and the sign alarm is output. Here, the difference ΔI between the current value Ii measured this time and the current value Ii-1 measured last time, which is obtained by the current monitoring unit 58, indicates the rate of change of the current value, which is the rate of change of the current value. It means that when the value exceeds a predetermined threshold value, a sign of a current value or more is determined and an alarm is given.

(モニタ装置による測定記録画面の表示)
図12は定周期測定による測定履歴を表示したモニタ装置の測定記録画面を示した説明図であり、電流監視部58により電流値異常の予兆が判定されて予兆警報が出力された場合を例にとって示している。
(Display of measurement recording screen by monitor device)
FIG. 12 is an explanatory diagram showing a measurement recording screen of the monitor device that displays the measurement history by the constant cycle measurement, and is an example of a case where the current monitoring unit 58 determines a sign of a current value abnormality and outputs a sign alarm. Shown.

図12に示すように、図5の表示パネル50で例えば手動通報電流値異常灯128及び手動通報電流値異常予兆点灯130が黄色点灯して電流値異常及びその予兆警報の代表表示が行われた場合、図3に示したように、パネル扉62を開いてモニタ装置46のモニタ画面70で所定の画面操作を行うと、定周期測定により測定して記憶された測定履歴の読み出しにより測定記録画面72が表示される。 As shown in FIG. 12, for example, the manual notification current value abnormality lamp 128 and the manual notification current value abnormality sign lighting 130 are lit in yellow on the display panel 50 of FIG. 5, and a representative display of the current value abnormality and its sign alarm is performed. In this case, as shown in FIG. 3, when the panel door 62 is opened and a predetermined screen operation is performed on the monitor screen 70 of the monitor device 46, the measurement recording screen is read by reading the measurement history measured and stored by the fixed cycle measurement. 72 is displayed.

測定記録画面72の右側には、ページ表示73、ページ切替ボタン74,75、ファイル保存ボタン76及びメモリ取出ボタン77が配置される。 On the right side of the measurement recording screen 72, a page display 73, page switching buttons 74 and 75, a file save button 76, and a memory eject button 77 are arranged.

ページ切替ボタン74,75を操作することで測定履歴詳細情報79のページ切替えを可能としている。ファイル保存ボタン76は測定結果のメモリ格納を指示する。メモリ取出ボタン77は防災受信盤10から電流値測定情報を記憶したメモリを取り出す場合に操作する。 By operating the page switching buttons 74 and 75, it is possible to switch the page of the measurement history detailed information 79. The file save button 76 instructs the memory storage of the measurement result. The memory eject button 77 is operated when ejecting the memory storing the current value measurement information from the disaster prevention receiving panel 10.

測定記録画面72の画面中央に表示された測定履歴詳細情報79は、前記(1)の予兆閾値範囲の設定による電流値異常の予兆判定を例にとっている。ここで、回線番号002にあっては、測定値が0.75mAであり、予兆上限値0.75mAに達していることから、予兆判定には「NG」の表示により電流値異常の予兆が示されている。 The measurement history detailed information 79 displayed in the center of the measurement recording screen 72 takes as an example the predictive determination of the current value abnormality by setting the predictive threshold range in (1). Here, in the line number 002, the measured value is 0.75 mA, and the upper limit of the sign has reached 0.75 mA. Therefore, the sign of the current value abnormality is indicated by the display of "NG" in the sign determination. Has been done.

また、回線番号004にあっては、測定値が1.25mAであり、異常上限値1.00mAを超えていることから、異常判定には「NG」の表示により電流値異常が示されている。この場合、測定値1.25mAは予兆上限値0.75mAも超えていることから、当然に、予兆判定には「NG」の表示により予兆が示されている。 Further, in the line number 004, the measured value is 1.25 mA, which exceeds the abnormal upper limit value of 1.00 mA. Therefore, the current value abnormality is indicated by the display of "NG" in the abnormality determination. .. In this case, since the measured value of 1.25 mA also exceeds the upper limit of the sign of 0.75 mA, the sign is naturally indicated by the display of “NG” in the sign determination.

測定記録画面72の下側には、回線選択ボタン78が配置され、回線選択ボタン78を操作すると、図13に示す測定記録絞込み画面80の表示に切り替えられる。 A line selection button 78 is arranged below the measurement recording screen 72, and when the line selection button 78 is operated, the display can be switched to the measurement record narrowing screen 80 shown in FIG.

図13の測定記録絞込み画面80には、系統選択部81、装置選択部82、区画選択部83、確定ボタン84、解除ボタン85、ページ表示86、ページ切替ボタン87,88、及び閉鎖ボタン89が設けられている。 The measurement record narrowing screen 80 of FIG. 13 includes a system selection unit 81, a device selection unit 82, a division selection unit 83, a confirmation button 84, a release button 85, a page display 86, page switching buttons 87 and 88, and a closing button 89. It is provided.

系統選択部81は上り線と下り線から選択する。装置選択部82は、手動通報、消火栓、ダクトから選択する。区画選択部83は区画番号を入力する。 The system selection unit 81 selects from an up line and a down line. The device selection unit 82 selects from manual notification, fire hydrant, and duct. The section selection unit 83 inputs a section number.

測定記録絞込み画面80において、例えば「上り線の手動通報装置における区画01」の測定記録に絞込みたい場合には、図示のように、系統選択部81に「上り線」、装置選択部82に「手動通報」、区画選択部83に「01」を設定し、確定ボタン84を操作すると、対応する絞込み測定記録90が表示される。 On the measurement record narrowing screen 80, for example, when it is desired to narrow down to the measurement record of "section 01 in the manual notification device for the up line", as shown in the figure, the system selection unit 81 has an "up line" and the device selection unit 82 has a "up line". When "manual notification" and "01" are set in the section selection unit 83 and the confirmation button 84 is operated, the corresponding narrowing measurement record 90 is displayed.

この状態で解除ボタン85を操作すると、絞込み条件及び絞込み測定記録90がクリアされる。また、閉鎖ボタン89を操作すると、図12の測定記録画面72に戻る。 When the release button 85 is operated in this state, the narrowing condition and the narrowing measurement record 90 are cleared. When the closing button 89 is operated, the screen returns to the measurement recording screen 72 of FIG.

このような測定記録絞込み画面80の機能を利用することで、記憶されている膨大な測定記録の中から、系統、装置、区画の組み合わせた絞込み条件の設定により測定記録を絞り込んで表示させることができ、例えば、電流値異常を起こした適宜の装置の回線劣化状況等の判断を効率良く行うことを可能とする。 By using such a function of the measurement record narrowing screen 80, it is possible to narrow down and display the measurement record by setting the narrowing condition that combines the system, the device, and the section from the huge number of stored measurement records. It is possible, for example, to efficiently determine the line deterioration status of an appropriate device that has caused an abnormality in the current value.

なお、測定記録の絞込み条件としては、系統、装置、区画に加え、期間を選択できるようにしても良い。 As the conditions for narrowing down the measurement records, a period may be selected in addition to the system, device, and section.
