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。 TECHNICAL FIELD The present invention relates to a tunnel disaster prevention system for connecting a terminal device such as a notification device or a detector installed in a tunnel to a disaster prevention reception panel to monitor an abnormality in the tunnel.
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。 BACKGROUND ART Conventionally, an emergency facility is installed in a tunnel such as a road for automobiles in order to protect a person and a vehicle from a fire accident occurring 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。 As such an emergency facility, a fire detector, a manual notification device, and an emergency telephone are installed to monitor and report a fire, and a fire hydrant device is installed to extinguish the fire and prevent the spread of fire. In order to protect the inside of the duct from fire, a water spray that sprays fire extinguishing water from the water spray head is installed, and a disaster prevention reception board that monitors and controls the terminal equipment of these emergency facilities is installed to build a tunnel disaster prevention system. is 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 reception board and terminal equipment is roughly divided into the R type transmission method and the P type direct transmission method. The R-type transmission method enables individual management by connecting a terminal device such as a fire detector whose address is set to a transmission line and performing detection and control for each terminal device by transmission control. The P-type direct delivery system divides the terminal device into predetermined partition units according to the type of the terminal device, connects a plurality of terminal devices belonging to the same partition to the signal line drawn out in the partition unit, and performs detection and control for each signal line unit.
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 a P-type direct delivery type tunnel disaster prevention system, terminal devices such as a manual notification device, a fire hydrant activation device, and a duct temperature detector have a signal output unit operated or detected as a non-voltage a contact switch, A non-voltage a contact switch is connected to the signal line drawn from the disaster prevention reception board. The no-voltage a-contact switch is normally off in the monitoring state, and is turned on by an operation or a detection operation to output a no-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 from the disaster prevention receiver board to one side of the signal line via a pull-up resistor, and in the steady monitoring state where the non-voltage a-contact switch is turned off, most current consumption flows in the signal line. However, the power supply voltage between the signal lines as seen from the disaster prevention reception board is maintained at approximately the power supply voltage. When the non-voltage a contact switch is turned on, current flows through the signal line, and the voltage between the signal lines as seen from the disaster prevention receiver panel drops to approximately zero volt. A voltage drop is detected and a reception signal indicating the operation or detection of the terminal device is output 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 notification signal from a manual notification device, the disaster prevention reception panel performs control operations such as fire display, lighting control of response lamps on the terminal side, manual notification section display, output of fire pump activation signal, and remote monitoring. Fire control signals are transmitted to external equipment such as control equipment, television monitoring equipment, variable road information board equipment, tunnel ventilation equipment, and lighting equipment to perform predetermined coping control.

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-dispatch tunnel disaster prevention system, insulation deterioration is progressing due to deterioration over time of the signal line (external cable) connecting the terminal equipment, and the signal line connecting the terminal equipment. In the normal monitoring condition, more current than expected flows, and the disaster prevention reception panel determines that the signal has been received by the operation or detection operation of the terminal equipment and performs an alarm operation, and also remote monitoring control equipment, TV monitoring equipment, variable roads. It is often the case that other equipment such as information board equipment, tunnel ventilation equipment, and lighting equipment are interlocked with each other to block 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 reception panel, 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. Is measured and recorded at a fixed cycle, and when the measured current is out of a predetermined threshold range, an abnormal current value of the signal line is determined and an alarm is issued.
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 a fire alarm signal is output from the fire prevention reception board and a fire alarm is output, or if a fault in the signal line is detected and a fault alarm is output, the fire alarm signal will be output during the subsequent investigation work. There is a case where the fire history or the troubled circuit in which the trouble is detected may be displayed by displaying the measurement history measured by the current monitoring device to check the state of the fired circuit or the troubled circuit.
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 a current monitoring device is conventionally installed in a separate housing for the disaster prevention reception panel, transmission and processing functions that send fire information and failure information from the disaster prevention reception panel to the current measurement device and store it with the measurement history However, 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 reception panel, a tunnel system diagram is placed on the graphic panel located on the front of the housing, and a line indicator light is divided into a manual reporting device and a fire hydrant activation device in the system diagram. When the fire alarm signal is received from the manual alarm device and the fire alarm is output, the line indicator light corresponding to the manual alarm device is turned on to display the fire occurrence area and the fire hydrant is activated. When a pump activation signal is received from the device, the line indicator lamp corresponding to the fire hydrant activation device is turned on to display the section in which the fire hydrant is activated.
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 reception panel also monitors the signal line for disconnection, and the front panel of the housing displays a 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 has occurred, and there is a problem that it cannot be easily confirmed in which section the signal line is in 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。 The present invention integrates the function of a current monitoring device into a disaster prevention reception panel to simplify the equipment configuration and processing, and uses a line indicator light provided corresponding to a signal line to prevent a disconnection fault other than a fire. An object of the present invention is to provide a tunnel disaster prevention system capable of easily grasping an abnormal current value or a signal line in which 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。
[Outline 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 tunnel 1a and a down tunnel 1b are constructed as a tunnel for an automobile road, and the up tunnel 1a and the down tunnel 1b are connected by an evacuation contact 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 ascending line tunnel 1a and the descending line tunnel 1b, fire hydrant devices 18 are installed, for example, at intervals of 50 meters along the wall surface of the observer passage in the longitudinal direction of the tunnel.
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 accommodates a hose with a nozzle in the fire hydrant door, and when a fire occurs, open the fire hydrant door and pull out the hose with a nozzle. The switch 14 is turned on to start the fire 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。 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 that functions as a contact means is turned on, a fire hydrant activation signal and a 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 activation switch used by the fire brigade, but since the system is the same switch that outputs the same pump activation signal as the fire hydrant valve opening/closing detection switch 14, It will be described as a fire hydrant valve opening/closing detection switch (including a pump start switch) 14. In addition to the fire hydrant device 18, the manual notification device 16 is also installed in the emergency telephone box, 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 duct temperature detector, and the like are provided as tunnel emergency equipment, but they are not shown.
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, for example, at intervals of 25 meters or 50 meters along the wall in the longitudinal direction of the tunnel, and monitoring areas are set on both sides of 25 meters or 50 meters on the left and right sides to detect flames caused by a fire and report a 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 water spray equipment.The main valve is driven to open by the remote opening control of the electric motor operated valve, and fire extinguishing water is discharged from the multiple water spray heads installed in the longitudinal direction above the tunnel wall surface. Protect the tunnel frame from fire.

(予兆閾値範囲の設定による電流値異常の予兆判定)
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。
(Prediction of current value abnormality by setting warning threshold range)
FIG. 7 is a graph showing the sign determination of the current value abnormality by setting the sign threshold range. FIG. 7 shows, for example, a daily change in the current value of the measurement history obtained by the periodic measurement from the current day (1 day) to 18 days before the current day. For such a current value measurement history, a lower limit value Ith1 and an upper limit value Ith4 for determining a current value abnormality are set, and a current value is within a threshold range Ith1 to Ith4 for determining a current value abnormality. A sign lower limit value Ith2 and a sign upper limit value Ith3 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 the narrower predictive threshold range Ith2 to Ith3 within the threshold range Ith1 to Ith4 for determining the abnormal current value, and the measured current value Ii is the predictive threshold range. When it deviates from Ith2 to Ith3, that is,
Ith2≧Ii>Ith1 or Ith4>Ii≧Ith3
In the case of, the sign of the current value abnormality is determined and the sign warning is output.
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 periodic measurement on the current day (first day) has reached the sign upper limit Ith3. Therefore, the current monitoring unit 58 determines the current value of the measured current value. The sign of abnormality is judged and a sign warning 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132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。 In addition, the current monitoring unit 58, when the sign of the current value abnormality is determined in the fixed cycle measurement, the automatic measurement or the manual measurement, the manual notification current value abnormality sign lamp 132 or the fire hydrant in the display panel 50 shown in FIG. The current value abnormality sign lamp 134 is lit in yellow to perform a representative display control.
(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、測定履歴の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。
(Signal judgment of abnormal current value due to difference from average current)
FIG. 8 is a graph showing the sign determination of the current value abnormality based on the 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 periodic measurement on the current day (the first day) determines that the current value is abnormal. If the difference ΔI between the measured current value Ii and the average current value Ia exceeds a predetermined sign threshold value ΔIth, the sign of the current value abnormality is determined, provided that it is within the threshold range Ith1 to Ith4. Then, control is performed to output a warning sign.
図6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. 6, the difference ΔI between the current value Ii and the average current value Ia measured by the periodic measurement on the current day (first day) is equal to or larger than the predictive threshold value ΔIth. Therefore, the current monitoring unit 58 Judges the sign of the current value abnormality in 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。
(Signal judgment of abnormal current value due to the difference from the current value measured last time)
FIG. 9 is a graph showing the sign determination of the current value abnormality based on the difference from the previously measured current value. As shown in FIG. 9, the current monitoring unit 58 confirms that the current value Ii measured by the constant cycle measurement on the current day (first day) is within the threshold range Ith1 to Ith4 for determining the current value abnormality. As a condition, when the difference ΔI from the previously measured current value Ii−1 exceeds a predetermined sign threshold ΔIth, the sign of the current value abnormality is determined and a sign warning is output. Here, the difference ΔI between the current value Ii measured this time and the current value Ii-1 measured last time obtained by the current monitoring unit 58 indicates the rate of change of the current value. This means that a sign of a current value or more is determined and an alarm is issued when the threshold value is equal to or higher than a predetermined threshold.

(Display of measurement record screen by monitor device)
FIG. 12 is an explanatory diagram showing a measurement recording screen of the monitor device displaying the measurement history of the fixed cycle measurement, and taking as an example the case where the current monitoring unit 58 determines the sign of the current value abnormality and outputs the sign alarm. Shows.
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, on the display panel 50 of FIG. 5, the manual notification current value abnormality lamp 128 and the manual notification current value abnormality predictive lighting 130 are illuminated in yellow, and the representative display of the current value abnormality and its predictive warning 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 device 46, the measurement record screen 72 is displayed by reading the measurement history that is measured by the periodic measurement and stored. It
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, the page of the measurement history detailed information 79 can be switched. The file save button 76 gives an instruction to store the measurement result in the memory. The memory take-out button 77 is operated when taking out the memory storing the current value measurement information from the disaster prevention receiver 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 detailed measurement history information 79 displayed in the center of the measurement recording screen 72 is an example of the sign determination of the current value abnormality by the setting of the sign threshold range in (1) above. Here, in line number 002, the measured value is 0.75 mA, and since the sign upper limit value of 0.75 mA is reached, the sign “NG” is displayed in the sign judgment to indicate the sign of the abnormal current value. 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 case of the line number 004, the measured value is 1.25 mA and exceeds the abnormal upper limit value of 1.00 mA. Therefore, the abnormality judgment indicates that the current value is abnormal. .. In this case, since the measured value of 1.25 mA exceeds the sign upper limit value of 0.75 mA, the sign of "NG" is naturally displayed 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. When the line selection button 78 is operated, the display is switched to the measurement recording 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。 On the measurement record narrowing screen 80 of FIG. 13, a system selection section 81, a device selection section 82, a section selection section 83, a confirm button 84, a release button 85, a page display 86, page switching buttons 87, 88, and a close button 89 are displayed. 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93は区画番号を入力する。 The system selection unit 81 selects from the up line and the down line. The device selection unit 82 selects from manual notification, fire hydrant, and duct. The partition selection unit 93 inputs the partition 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 narrowing down to the measurement record of “section 01 in the manual reporting device for the up line”, as shown in the figure, the system selecting unit 81 displays the “up line” and the device selecting unit 82 displays the “up line”. If “01” is set in the section selection section 83 and the confirm button 84 is operated, the corresponding narrowed 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-down condition and the narrowing-down measurement record 90 are cleared. When the close 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 the function of the measurement record narrowing screen 80 as described above, it is possible to narrow down and display the measurement records by setting narrowing conditions that are a combination of the system, the device, and the section from among the enormous stored measurement records. Therefore, for example, it is possible to efficiently determine the line deterioration status of an appropriate device that has an abnormal 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 a condition for narrowing down the measurement record, the period may be selected in addition to the system, device, and section.
