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 in which terminal devices such as a notification device and a detector installed in a tunnel are connected to a disaster prevention receiving board and an abnormality in the tunnel is monitored.
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 are equipped with fire detectors, manual notification devices, emergency telephones for fire monitoring and reporting, fire hydrant devices for fire extinguishing and fire prevention, and tunnel enclosures and In order to protect the inside of the duct from fire, a water spray that sprays water for fire extinguishing from the water spray head is installed, and a disaster prevention reception panel that monitors and controls the terminal equipment of these emergency facilities is built 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。   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 enables individual management in which a terminal device such as a fire detector having an address set on the transmission line is connected and detection and control are performed for each terminal device by transmission control. In the P-type direct transmission method, a plurality of terminal devices belonging to the same partition are connected to a signal line drawn out in each partition unit according to the type of terminal device, and detection and control are performed in signal line units.
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 transmission type tunnel disaster prevention system, terminal devices such as a manual notification device, a fire hydrant starting device, a duct temperature detector, etc. are configured with a signal output unit by operation or detection as a no-voltage a contact switch, A no-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 turned off in a monitoring state, and is turned on by an operation or 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 side to one of the signal lines via a pull-up resistor, and in a steady monitoring state in which the no-voltage a contact switch is turned off, current consumption almost flows through the signal line. First, the power supply voltage between the signal lines as seen from the disaster prevention reception board is maintained at substantially the power supply voltage. When the no-voltage a contact switch is turned on, current flows in the signal line, and the voltage between the signal lines as seen from the disaster prevention receiving board decreases to approximately zero volts. The disaster prevention receiving board increases the current consumption of the signal line or between the signal lines. A voltage drop is detected and a reception signal indicating 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, if it is a fire notification signal from a manual notification device, the disaster prevention reception board performs control operations such as fire display, lighting control of the response lamp on the terminal side, manual notification section display, output of fire extinguishing pump start signal, and remote monitoring Fire notification signals are transmitted to external equipment such as control equipment, television monitoring equipment, variable road information board equipment, tunnel ventilation equipment, lighting equipment, etc., so that predetermined countermeasure control is 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-sending tunnel disaster prevention system, the signal line connecting the terminal equipment has been deteriorated due to deterioration over time of the signal line (external cable) connecting the terminal equipment. More current than expected in the normal monitoring state flows, and the disaster prevention reception board performs alarm operation by judging that the signal is received by the operation or detection operation of the terminal equipment, as well as remote monitoring control equipment, TV monitoring equipment, variable road Interlocking other equipment such as information board equipment, tunnel ventilation equipment, lighting equipment, etc., often prevents the passage of the tunnel.
ところで、従来の電流監視装置にあっては、定周期測定で得られた信号回線毎の電流値が所定の上限値と下限値で決まる閾値範囲を外れた場合に電流値異常と判断して警報するようにしているが、電流値異常が判定される前から信号回線の絶縁劣化等による電流値の変動が現れていることが想定され、このような電流値異常の予兆を早い段階で知ることができれば、近い将来、電流値異常となることが予想でき、早い段階から適切な対応を準備することが可能となる。   By the way, in the conventional current monitoring device, when the current value for each signal line obtained by the periodic measurement is out of the threshold range determined by the predetermined upper limit value and lower limit value, it is determined that the current value is abnormal and an alarm is given. However, it is assumed that fluctuations in the current value due to insulation deterioration of the signal line, etc. appear before the current value abnormality is judged, and it is possible to know early signs of such current value abnormality. If it is possible, it can be predicted that the current value will become abnormal in the near future, and appropriate measures can be prepared from an early stage.
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、信号回線の電流値異常が判定される前にその予兆を捉えて警報可能とすると共に、予兆が判定された後の電流値の詳細な変化を把握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 the current monitoring device into the disaster prevention receiver and simplifies the equipment configuration and processing, and allows the alarm to be detected and detected before the current value abnormality of the signal line is determined, An object of the present invention is to provide a tunnel disaster prevention system capable of grasping a detailed change in current value after a sign is determined.

(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及び検知器を含む複数の端末機器と、防災受信盤に設けられ、信号回線により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測定履歴に含めて記憶すると共に電流値異常の警報を出力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、電流監視部は、測定された電流値が電流値異常を判定する閾値範囲内で大きく変化し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と共に、所定周期を短い周期に変更して電流値異常の予兆が判定された信号回線に流れる電流値を測定して記憶させるようにしたため、信号回線の絶縁劣化等に起因した電流値異常が判定されて警報される前の段階で、電流値異常の予兆を知り、近い将来、電流値異常が判定される可能性が高いといった問題を把握して適切な対処が可能となり、更に、1日1回といった測定周期を、電流値異常が判定された信号回線については、それより短い例えば1時間に1回といった測定周期に変更して電流値を測定することで、電流値異常の予兆が判定された後に、短時間でより詳細なデータを収集して判断することが可能となり、また、電流値異常の予兆が判定された後に、電流値異常となった場合にも、電流値異常が早期に判定されて警報することができる。
(Basic effect)
The present invention is provided with a plurality of terminal devices including a manual notification device and a detector for outputting a fire signal connected to each of a plurality of signal lines drawn into the tunnel from the disaster prevention reception board, and the disaster prevention reception board. A monitoring control unit that receives the fire signal through a line and outputs a fire alarm and a disaster prevention receiving panel, and measures current values flowing through a plurality of signal lines at predetermined intervals, stores them as a measurement history, and measures In a tunnel disaster prevention system comprising a current monitoring unit that determines a current value abnormality and stores it in a measurement history and outputs a current value abnormality alarm when the current value is outside a predetermined threshold range. When the measured current value greatly changes within the threshold range for determining the current value abnormality, the monitoring unit determines a sign of the current value abnormality and outputs a sign warning, and changes the predetermined period to a short period. Current value Since the current value flowing in the signal line for which a normal sign was determined was measured and stored, the current value abnormality was detected before the alarm was determined and an alarm was detected due to the insulation deterioration of the signal line. It is possible to take appropriate measures by grasping the problem that current value abnormality is likely to be judged in the near future, and to determine the current value abnormality at a measurement cycle of once a day. For signal lines, the current value is measured by changing to a shorter measurement cycle such as once per hour, and more detailed data is collected in a short time after the sign of an abnormal current value is determined. In addition, even when a current value abnormality occurs after a sign of a current value abnormality is determined, a current value abnormality can be determined early and a warning can be issued.
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。   In addition, since the current monitoring unit is provided integrally with the disaster prevention receiving board, the equipment configuration and processing are simplified and the installation space can be reduced as compared with the case where the current monitoring device is provided in a separate housing.
(予兆判定した信号回線の測定履歴の絞込み表示による効果)
また、トンネル防災システムは、更に、前記防災受信盤の筐体内に配置されたモニタ装置を備え、電流監視部は、所定の履歴読出操作を検出した場合に記憶された測定履歴を読み出してモニタ装置に画面表示させ、電流値異常の予兆が判定された信号回線を指定した絞込み操作を検出した場合に、測定履歴の中から指定された信号回線の履歴情報を抽出してモニタ装置に画面表示させるようにしたため、測定履歴の中に1日1回の測定周期による電流値とそれより短い例えば1時間に1回の測定周期による電流値が測定履歴として記憶されることとなり、測定履歴をそのまま読み出すと測定周期の異なる電流値が時系列に表示されるが、短い周期で測定された電流値異常の予兆が判定された信号回線の電流値に絞り込んで時系列に表示させることができ、電流値異常の予兆が判定された信号回線の電流値の変化を詳しく知ることを可能とする。
(Effects of narrowed display of measurement history of signal line with predictive judgment)
The tunnel disaster prevention system further includes a monitor device disposed in the housing of the disaster prevention reception panel, and the current monitoring unit reads the measurement history stored when a predetermined history read operation is detected, and the monitor device When a narrowing operation that specifies a signal line for which a sign of current value abnormality has been detected is detected, the history information of the specified signal line is extracted from the measurement history and displayed on the monitor device. As a result, the current value in the measurement history is stored in the measurement history as a measurement history, and the current value in the measurement cycle shorter than that, for example, once in one hour is read as the measurement history. Current values with different measurement periods are displayed in time series, but the current values of signal lines that have been measured in a short period are narrowed down to the current value of the signal line that has been determined and displayed in time series Bets can be, sign of the current value abnormalities allows to know in detail the change in the current value of the signal line is determined.
(予兆閾値範囲の設定による電流値異常の予兆判定の効果)
また、電流監視部は、所定の閾値範囲内に、それより狭い所定の予兆閾値範囲を設定し、測定された電流値が予兆閾値範囲を外れた場合に電流値異常の予兆を判定するようにしたため、定周期測定された信号回線の電流値が電流値異常を判定する閾値範囲内で変動し、その範囲内に設定した予兆閾値範囲の上限値以上又は下限値以下となると電流値異常の予兆を判定し、電流値異常が判定される前にその予兆を確実に判定して警報可能とする。
(Effect of predictive judgment of current value abnormality by setting predictive threshold range)
Further, the current monitoring unit sets a predetermined predictive threshold range narrower than the predetermined threshold range, and determines a predictor of an abnormal current value when the measured current value is out of the predictive threshold range. Therefore, when the current value of the signal line measured at a fixed cycle fluctuates within the threshold range for determining an abnormal current value, and becomes the upper limit value or lower limit value of the predictive threshold range set within that range, a sign of an abnormal current value is indicated. Before the current value abnormality is determined, the warning is reliably determined and the alarm is possible.
(平均電流との差による電流値異常の予兆判定の効果)
また、電流監視部は、測定履歴から過去の平均電流値を求め、測定された電流値と平均電流値との差が所定の閾値を超えて増減した場合に電流値異常の予兆を判定するようにしたため、例えば測定履歴につき過去1ケ月の移動平均電流を求め、測定した電流値が過去の平均電流値に対し大きく変化した場合に電流値異常の予兆を判定して警報することで、測定電流値の大きな変化を確実に捉えて電流値異常の予兆を警報できる。
(Effect of predicting current value abnormality due to difference from average current)
Further, the current monitoring unit obtains a past average current value from the measurement history, and determines a sign of an abnormality in the current value when the difference between the measured current value and the average current value exceeds or exceeds a predetermined threshold. Therefore, for example, the moving average current of the past month is obtained for the measurement history, and when the measured current value greatly changes with respect to the past average current value, a warning is given to determine a sign of an abnormality in the current value. A large change in the value can be detected with certainty and a warning of an abnormal current value can be warned.
また、電流値異常の予兆を判定する基準を過去の測定電流値の平均電流としていることで、過去の一部の測定電流値にノイズ等による測定値があっても、これに影響されることなく、確実に電流値異常の予兆を判定して警報可能とする。   In addition, since the standard for determining a sign of abnormal current value is the average current of past measured current values, even if there are measured values due to noise etc. in some past measured current values, it is affected by this It is possible to make a warning by reliably determining a sign of an abnormal current value.
(前回測定の電流値との差による電流値異常の予兆判定の効果)
また、電流監視部は、測定履歴の前回測定された電流値と新たに測定された電流値との差が所定の閾値を超えて増減した場合に電流値異常の予兆を判定するようにしたため、例えば1日1回といった定周期測定のサイクルで起きる電流値の大きな変化を確実に捉えて電流値異常の予兆を判定して警報可能とする。
(Effect of predictive judgment of current value abnormality due to difference from current value of previous measurement)
In addition, since the current monitoring unit is configured to determine a sign of an abnormality in the current value when the difference between the previously measured current value of the measurement history and the newly measured current value exceeds or exceeds a predetermined threshold, For example, a large change in the current value that occurs in a periodic measurement cycle such as once a day is reliably captured, and a warning of an abnormal current value is determined to enable an alarm.
(メインモニタ装置又は表示パネルと筐体内のモニタ装置による画面警報表示の効果)
また、トンネル防災システムは、更に、防災受信盤の筐体前面に配置されたメインモニタ装置又は表示パネルを備え、電流監視部は、電流値異常又は電流値異常の予兆が判定された場合に、メインモニタ装置の画面又は表示パネルに電流値異常又は電流値異常の予兆を代表表示させると共に筐体内のモニタ装置の画面に電流値異常又は電流値異常の予兆の詳細情報を表示させるようにしたため、電流監視部により電流値異常の予兆が判定されると、その予兆の代表表示が常に見ることのできるメインモニタ装置に画面表示されるか又は表示パネルに代表表示されることで、電流値異常の予兆を知り、必要に応じて筐体内に配置されたモニタ装置に画面表示された予兆詳細情報を見ることで、電流値異常の予兆が判定された信号回線の上り線か下り線かの系統、信号回線に接続されている装置名称、監視区画の番号等を知って、必要な対処が可能となる。
(Effect of screen alarm display by main monitor device or display panel and monitor device in housing)
In addition, the tunnel disaster prevention system further includes a main monitor device or a display panel arranged on the front surface of the housing of the disaster prevention reception board, and the current monitoring unit is configured to detect a current value abnormality or a sign of a current value abnormality. Since the main monitor device screen or display panel displays current value abnormality or a sign of current value abnormality as a representative and detailed information on current value abnormality or a sign of current value abnormality is displayed on the monitor device screen in the housing. When the current monitoring unit determines a sign of an abnormality in the current value, a representative display of the sign is displayed on the main monitor device that can always be seen or displayed on the display panel. Know the sign and, if necessary, check the detailed information displayed on the screen of the monitor device installed in the housing to determine whether the signal line has been detected abnormally. Ri line or lines, device name that is connected to the signal line, to know the number of the monitoring section, it is possible to necessary actions.

FIG. 6 is a graph showing a sign determination of an abnormal current value due to a difference from the average current. As shown in FIG. 6, 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 increases or decreases beyond a predetermined threshold ΔIth on the condition that the current value is within the threshold range Ith1 to Ith4, a sign of abnormal current value is given. Control to judge and output a warning warning.
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 measured by the periodic measurement on the current day (the first day) and the average current value Ia is equal to or greater than the threshold value ΔIth. For the measured current value, a sign of an abnormal current value is determined and a sign alarm is output.
(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7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7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が所定の閾値ΔIthを超えて増減した場合に、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。
(Predictive judgment of current value abnormality due to difference from current value of previous measurement)
FIG. 7 is a graph showing a sign determination of an abnormal current value due to a difference from the current value of the previous measurement. As shown in FIG. 7, the current monitoring unit 58 confirms that the current value Ii measured by the periodic measurement on the current day (the first day) is within a threshold range Ith1 to Ith4 for determining a current value abnormality. When the difference ΔI from the previously measured current value Ii−1 exceeds the predetermined threshold value ΔIth as a condition, control is performed to determine a sign of abnormal current value and output a sign warning. Here, the difference ΔI between the current value Ii measured this time obtained by the current monitoring unit 58 and the current value Ii−1 measured last time indicates the rate of change of the current value, which is the rate of change of the current value. This means that when a predetermined threshold value or more is reached, a warning that is greater than or equal to the current value is determined and an alarm is issued.
(電流値異常の予兆が判定された信号回線の測定処理)
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た場合、1日1回の通常の測定周期を、それより短い例えば1時間に1回といった短い周期に変更して、電流値異常の予兆が判定された信号回線に流れる電流値を測定して記憶させる制御を行う。
(Measurement processing for signal lines for which signs of abnormal current values have been determined)
When the current monitoring unit 58 determines a sign of abnormality in the measured current value, the current monitoring unit 58 changes the normal measurement cycle once a day to a shorter cycle such as once per hour. Then, control is performed to measure and store the value of the current flowing through the signal line for which a sign of abnormality in the current value is determined.
このような電流値異常が判定された信号回線の測定周期を短くすることで、電流値異常の予兆が判定された後に、短時間でより詳細なデータを収集して電流値の推移を判断することが可能となり、また、電流値異常の予兆が判定された後に、電流値異常となった場合にも、電流値異常が早期に判定されて警報することができる。   By shortening the measurement cycle of the signal line in which such current value abnormality is determined, after a sign of current value abnormality is determined, more detailed data is collected in a short time to determine the transition of the current value In addition, even when a current value abnormality occurs after a sign of a current value abnormality is determined, the current value abnormality can be determined early and a warning can be issued.
また、電流監視部58は、電流値異常の予兆が判定された信号回線について、短い測定周期による測定履歴が得られた状態で、電流値異常の予兆が判定された信号回線を指定した所定の絞込み操作を検出した場合に、測定履歴の中から指定された信号回線の履歴情報を抽出してモニタ装置46に画面表示させる制御を行う。   In addition, the current monitoring unit 58 is configured to specify a signal line for which a sign of current value abnormality has been determined in a state where a measurement history with a short measurement cycle is obtained for the signal line for which a sign of current value abnormality has been determined. When a narrowing operation is detected, control is performed so that history information of the designated signal line is extracted from the measurement history and is displayed on the monitor device 46.
このような電流値異常の予兆が判定された信号回線に絞り込んで測定履歴をモニタ装置46に画面表示させることで、電流値異常の予兆か判定された信号回線の電流値の変化を詳しく知ることができる。   By narrowing down to signal lines for which such a sign of current value abnormality has been determined and displaying the measurement history on the monitor device 46, it is possible to know in detail the change in the current value of the signal line that has been determined to be a sign of current value abnormality. Can do.

(Display of measurement record screen by monitor)
FIG. 8 is an explanatory view showing a measurement recording screen of a monitor device displaying a measurement history by periodic measurement, taking as an example a case where a predictor of current value abnormality is determined by the current monitoring unit 58 and a predictive alarm is output. Show.
図8に示すように、モニタ画面70には、メインモニタ装置44の画面に電流値異常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. 8, on the monitor screen 70, when a representative display of a warning sign of abnormal current value is displayed on the screen of the main monitor device 44, the panel door 62 is opened and monitored as shown in FIG. When a predetermined screen operation is performed with the device 46, the measurement record screen 72 is displayed by reading the measurement history measured and stored by the periodic measurement.
測定記録画面72の右側には、ページ表示74、ページ切替ボタン76,78、ファイル保存ボタン80及びメモリ取出ボタン82が配置される。   On the right side of the measurement recording screen 72, a page display 74, page switching buttons 76 and 78, a file save button 80, and a memory extraction button 82 are arranged.
ページ切替ボタン76,78を操作することで測定履歴詳細情報90のページ切替えを可能としている。ファイル保存ボタン80は測定結果のメモリ格納を指示する。メモリ取出ボタン82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。   The page switching of the measurement history detailed information 90 can be performed by operating the page switching buttons 76 and 78. The file save button 80 instructs to store the measurement result in the memory. The memory extraction button 82 is operated when the memory storing the current value measurement information is extracted from the disaster prevention receiving board 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90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 90 displayed at the center of the measurement record screen 72 is an example of predicting a current value abnormality by setting the predictive threshold range (1). Here, for the line number 002, since the measured value is 0.75 mA and has reached the predictive upper limit value 0.75 mA, a sign of an abnormal current value is indicated by displaying “NG” in the sign determination. Has been.
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 1.00 mA. Therefore, the abnormality determination indicates the current value abnormality by displaying “NG”. . In this case, since the measured value 1.25 mA exceeds the predictive upper limit value 0.75 mA, the predictor is naturally indicated by the indication “NG” in the predictor determination.
測定記録画面72の下側には、回線選択ボタン84、予兆回線選択ボタン86及び異常回線選択ボタン88が配置される。   On the lower side of the measurement record screen 72, a line selection button 84, a predictive line selection button 86, and an abnormal line selection button 88 are arranged.
回線選択ボタン86を操作すると、図9に示す測定記録絞込み画面92の表示に切り替えられる。   When the line selection button 86 is operated, the display is switched to the measurement record narrowing screen 92 shown in FIG.
図9の測定記録絞込み画面92には、系統選択部94、装置選択部96、区画選択部98、確定ボタン102、解除ボタン104、ページ表示106、ページ切替ボタン108,110、及び閉鎖ボタン112が設けられている。   9 includes a system selection unit 94, a device selection unit 96, a section selection unit 98, a confirmation button 102, a release button 104, a page display 106, page switching buttons 108 and 110, and a close button 112. Is provided.
系統選択部94は上り線と下り線から選択する。装置選択部96は、手動通報、消火栓、ダクトから選択する。区画選択部98は区画番号を入力する。   The system selection part 94 selects from an up line and a down line. The apparatus selection part 96 selects from a manual report, a fire hydrant, and a duct. The section selection unit 98 inputs a section number.
測定記録絞込み画面92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94に「上り線」、装置選択部96に「手動通報」、区画選択部98に「01」を設定し、確定ボタン102を操作すると、対応する絞込み測定記録114が表示される。   In the measurement record narrowing screen 92, for example, when it is desired to narrow down the measurement record of “section 01 in the uplink manual notification device”, “upline” is displayed in the system selection unit 94, and “ When “01” is set in the “manual report” and the section selection unit 98 and the confirmation button 102 is operated, the corresponding narrowed measurement record 114 is displayed.
この状態で解除ボタン104を操作すると、絞込み条件及び絞込み測定記録114がクリアされる。また、閉鎖ボタン112を操作すると、図7の測定記録画面72に戻る。   When the release button 104 is operated in this state, the narrowing condition and the narrowing measurement record 114 are cleared. When the close button 112 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92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 92, it is possible to narrow down and display the measurement records by setting the narrowing conditions combined with the system, device, and section from the enormous amount of stored measurement records. For example, it is possible to efficiently determine the line degradation status of an appropriate device that has caused 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。   In addition, as a condition for narrowing down measurement records, a period may be selected in addition to the system, device, and section.
