Description

本発明は、防災監視エリアに対応して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防災監視エリアの異常を監視する防災システムに関する。
The present invention relates to a disaster prevention system for monitoring an abnormality in a disaster prevention monitoring area by connecting a terminal device such as a notification device or a detector installed corresponding to the disaster prevention monitoring area to a disaster prevention receiving panel.

従来、自動車専用道路等のトンネルには、トンネル内で発生する火災事故から人身及び車両を守るため、非常用施設が設置されている。 Conventionally, emergency facilities have been installed in tunnels 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 are equipped with a fire detector, a manual notification device, an emergency telephone for fire monitoring and notification, a fire hydrant device for extinguishing a fire and preventing the spread of fire, and a tunnel frame. In order to protect the inside of the duct from fire, a 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. 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 a disaster prevention receiver and terminal equipment is roughly divided into an R-type transmission system and a P-type direct transmission system. The R-type transmission method connects a terminal device such as a fire detector whose address is set to 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 in the 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 the P-type direct delivery type tunnel disaster prevention system, the terminal equipment such as the manual notification device, the fire extinguisher activation device, and the duct temperature detector configures the signal output unit by operation or detection 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 receiving panel side via a pull-up resistor, and in the steady monitoring state where the non-voltage a contact switch is turned off, most of the current consumption flows in 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, current flows through the signal line, the voltage between the signal lines seen from the disaster prevention receiver drops to approximately 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 the fire extinguishing pump start signal, as well as remote monitoring. A fire alarm signal is transmitted to external equipment such as control equipment, TV monitoring equipment, variable road information board equipment, tunnel ventilation equipment, and lighting equipment so that predetermined response 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 transmission 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 close 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 constant cycle measurement deviates from 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 appear before the current value abnormality is determined, and it is necessary to know the signs of such current value abnormality at an early stage. If this is possible, it is expected that the current value will become abnormal in the near future, and it will be possible to prepare appropriate measures 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防災システムを提供することを目的とする。
The present invention integrates the functions of the current monitoring device into the disaster prevention receiver to simplify the equipment configuration and processing, and also enables warning by catching the sign before the current value abnormality of the signal line is determined. It is an object of the present invention to provide a disaster prevention system capable of grasping a detailed change of a current value after a sign is determined.

(基本的な効果)
本発明は、防災監視エリアに対応して配置した端末機器から信号回線を介して送信され防災受信盤で受信される火災に関する所定の信号に基づき火災警報を出力する防災システムに於いて、防信号回線に流れる電流値を所定の周期で測定し、測定した電流値の異常である電流値異常を所定の電流値異常判定条件に基づいて判定し、電流値異常の発生が予測される状態である電流値異常の予兆を所定の電流値異常の予兆判定条件に基づいて判定し、所定の周期を現状設定された周期よりも短い周期に変更して電流値異常の予兆と判定された信号回線に流れる電流値を測定する制御部を備え、制御部で電流値異常と判定した場合に、電流値異常の警報を出力し、制御部で電流値異常の予兆と判定した場合に、電流値異常の予兆警報を出力するため、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、例えば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 a disaster prevention system that outputs a fire alarm based on a predetermined signal regarding a fire transmitted from a terminal device arranged corresponding to a disaster prevention monitoring area via a signal line and received by a disaster prevention receiver. The current value flowing through the line is measured at a predetermined cycle, and the current value abnormality, which is an abnormality of the measured current value, is determined based on the predetermined current value abnormality judgment condition, and the occurrence of the current value abnormality is predicted. The sign of the current value abnormality is judged based on the predetermined current value abnormality sign judgment condition, and the predetermined cycle is changed to a cycle shorter than the currently set cycle to make the signal line judged to be the sign of the current value abnormality. It is equipped with a control unit that measures the flowing current value. When the control unit determines that the current value is abnormal, it outputs an alarm for the current value abnormality, and when the control unit determines that it is a sign of the current value abnormality, the current value is abnormal. Since a sign alarm is output, it is possible to know the sign of a current value abnormality and determine a current value abnormality in the near future before the current value abnormality due to insulation deterioration of the signal line is determined and alarmed. It is possible to grasp the problem such as high probability and take appropriate measures, and further, for example, the measurement cycle is once a day, and for the signal line where the current value abnormality is judged, it is shorter, for example, once an hour. By changing the measurement cycle and measuring the current value, it is possible to collect and judge more detailed data in a short time after the sign of the current value abnormality is determined, and also the sign of the current value abnormality. Even if the current value abnormality occurs after the determination is made, the current value abnormality can be determined at an early stage and an alarm can be given.

また、制御部を防災受信盤に設けた場合には、防災受信盤は電流監視装置の機能を含むため、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, when the control unit is provided in the disaster prevention receiving board, the disaster prevention receiving board includes the function of the current monitoring device, so that the equipment configuration and processing become easier than when the current monitoring device is provided in a separate housing. , Installation space can also be reduced.

(電流値及び警報に関する表示の効果)
また、表示部を備え、制御部が信号回線について電流値異常又は電流値異常の予兆と判定した場合に、測定した電流値と、電流値異常又は電流値異常の予兆を示す情報とを表示部に表示するようにしたため、制御部により電流値異常又は電流値異常の予兆が判定されると、電流値異常又は電流値異常の予兆の情報が表示部に表示されることで、電流値異常又は電流値異常の予兆を知り、必要に応じて表示部に画面表示された電流値を見ることで、電流値異常又は電流値異常の予兆と判定された信号回線の詳細情報を知ることが可能となる。
(Effect of display regarding current value and alarm)
Further, a display unit is provided, and when the control unit determines that the signal line is a sign of current value abnormality or current value abnormality, the measured current value and information indicating a sign of current value abnormality or current value abnormality are displayed. When the control unit determines the current value abnormality or the sign of the current value abnormality, the information of the current value abnormality or the sign of the current value abnormality is displayed on the display unit, so that the current value abnormality or the current value abnormality is displayed. By knowing the sign of the current value abnormality and seeing the current value displayed on the screen as needed, it is possible to know the detailed information of the signal line determined to be the sign of the current value abnormality or the current value abnormality. Become.

(測定された信号回線の電流値の絞込み表示による効果)
また、所定の要求を検出した場合に、表示部に所定の要求に対応した電流値を表示し、これ以外の電流値を表示しないようにしたため、表示されている電流値の中に例えば1日1回の測定周期による電流値と、電流値異常の予兆と判定されて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表示されることとなり、電流値をそのまま表示すると例えば測定周期の異なる電流値が時系列に表示されるが、所定の要求に対応して絞込み表示され、例えば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。
(Effect of narrowing down display of measured current value of signal line)
In addition, when a predetermined request is detected, the current value corresponding to the predetermined request is displayed on the display unit, and other current values are not displayed. Therefore, for example, one day is included in the displayed current value. The current value due to one measurement cycle and the current value due to the measurement cycle once per hour, which is shorter than the current value determined to be a sign of abnormal current value, are displayed. If the current value is displayed as it is, for example, the measurement cycle. The different current values are displayed in chronological order, but they are narrowed down and displayed in response to a predetermined request. It is possible to know in detail the change in the current value of the signal line in which the sign of the current value abnormality 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、電流値が所定の閾値範囲外となった場合に電流値異常と判定し、電流値が所定の閾値範囲内であって、当該所定の閾値範囲より狭い閾値範囲外となった場合に電流値異常の予兆と判定するため、例えば定周期測定された信号回線の電流値が電流値異常と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外となると電流値異常の予兆と判定し、電流値異常が判定される前にその予兆と確実に判定して警報可能とする。
(Effect of predictive judgment of current value abnormality by setting the sign threshold range)
Further, when the current value is outside the predetermined threshold range, it is determined that the current value is abnormal, and when the current value is within the predetermined threshold range and is outside the narrower threshold range than the predetermined threshold range, the current is generated. In order to determine that the value is abnormal, for example, the current value of the signal line measured at regular intervals fluctuates within the threshold range for determining the current value abnormality, and if it is outside the predictive threshold range set within that range, the current value is abnormal. It is determined that it is a sign, and it is surely determined that it is a sign before the current value abnormality is determined, and an 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、制御部が所定の期間に於いて測定した電流値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に基づいて制御部が電流値異常の予兆と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変化した場合に電流値異常の予兆と判定して警報することで、測定電流値の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 predictive judgment of current value abnormality due to difference from average current)
Further, the control unit obtains the past average current value from the current value measured in a predetermined period, and the control unit determines that the current value is abnormal based on the difference between the measured current value and the average current value. Therefore, for example, the moving average current for the past one month is obtained from the measurement history, and when the measured current value changes with respect to the past average current value, it is determined as a sign of current value abnormality and an alarm is given to measure the current. It is possible to reliably catch changes in the value and warn of signs of abnormal current value.

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 the sign of abnormal current value is the average current of past measured current values, even if some of the measured current values in the past have measured values due to noise, etc., they will be affected by this. Instead, it is possible to reliably determine the sign of an abnormal current value and make an 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の効果)
また、制御部が所定の期間に於いて測定した電流値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に基づいて制御部が電流値異常の予兆と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変化を確実に捉えて電流値異常の予兆と判定して警報可能とする。
(Effect of predictive judgment of current value abnormality due to difference from the current value of the previous measurement)
Further, the control unit obtains the past average current value from the current value measured in a predetermined period, and the control unit determines that the current value is abnormal based on the difference between the measured current value and the average current value. Therefore, it is possible to reliably grasp the change in the current value that occurs in the cycle of the fixed cycle measurement such as once a day, determine that it is a sign of the current value abnormality, and make an alarm.

[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 tunnels 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 a fire hydrant valve open / close detection switch 14 and a manual notification device 16 as terminal devices, and by turning on the non-voltage a contact switch that functions as a contact means, 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 will be applied. This will be described as a fire hydrant valve open / close detection switch (including a pump start switch) 14.

(予兆閾値範囲の設定による電流値異常の予兆判定)
図5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5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 sign threshold range)
FIG. 5 is a graph showing a sign determination of a current value abnormality by setting a sign threshold range. FIG. 5 shows, for example, the diurnal change of the current value of the measurement history obtained by the fixed cycle measurement from the present 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5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. 5, 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5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. 5, the current value Ii measured by the fixed cycle measurement on the current day (1st day) has reached the upper limit of the sign Is3, and therefore, the current monitoring unit 58 has the current value of the measured current value. A sign of abnormality is determined and a sign alarm is output.

(平均電流との差による電流値異常の予兆判定)
図6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6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。
(Determination of sign of current value abnormality based on the difference from the average current)
FIG. 6 is a graph showing a sign determination of a current value abnormality 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 fixed cycle measurement on 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 increases or decreases beyond the predetermined threshold value ΔIth on condition that the current value is within the range of the threshold range Is1 to Is4, the sign of the current value abnormality is determined. Then, control is performed to output a sign alarm.

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 and the average current value Ia measured by the constant cycle measurement on the current day (1st day) is equal to or greater than the threshold value ΔIth. Therefore, the current monitoring unit 58 is used. With respect to the measured current value, the 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。
(Determination of sign of current value abnormality based on the difference from the current value measured last time)
FIG. 7 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. 7, the current monitoring unit 58 indicates that the current value Ii measured by the constant cycle measurement on the current day (day 1) 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 increases or decreases beyond a predetermined 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.

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 of signal line for which a sign of current value abnormality is determined)
When the current monitoring unit 58 determines that the measured current value is a sign of an abnormality in the current value, the current monitoring unit 58 changes the normal measurement cycle once a day to a shorter cycle, for example, once an hour. , Control is performed to measure and store the current value flowing through the signal line where the sign of the current value abnormality 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 a current value abnormality is determined, after the sign of the 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 if a current value abnormality occurs after a sign of a current value abnormality is determined, the current value abnormality can be determined at an early stage and an alarm can be given.

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。 Further, the current monitoring unit 58 designates a predetermined signal line in which the sign of the current value abnormality is determined in a state where the measurement history with a short measurement cycle is obtained for the signal line in which the sign of the current value abnormality is determined. When the narrowing operation is detected, the history information of the designated signal line is extracted from the measurement history and controlled to be displayed on the screen of the monitoring 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 the signal line where the sign of the current value abnormality is determined and displaying the measurement history on the screen of the monitor device 46, it is possible to know in detail the change in the current value of the signal line determined to be the sign of the current value abnormality. Can be done.

(モニタによる測定記録画面の表示)
図8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 on the monitor)
FIG. 8 is an explanatory diagram showing a measurement recording screen of a monitor device that displays a measurement history by constant cycle measurement, and is an example of a case where a sign of a current value abnormality is determined by the current monitoring unit 58 and a sign alarm is output. Shows.

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, when a representative display of a sign alarm of a current value abnormality is displayed on the screen of the main monitor device 44 on the monitor screen 70, the panel door 62 is opened to monitor as shown in FIG. When a predetermined screen operation is performed by the device 46, the measurement recording screen 72 is displayed by reading out the measurement history measured and stored by the constant cycle 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, a page switching button 76, 78, a file save button 80, and a memory eject 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。 By operating the page switching buttons 76 and 78, it is possible to switch the page of the measurement history detailed information 90. The file save button 80 instructs to store the measurement result in the memory. The memory eject button 82 is operated when the memory in which the current value measurement information is stored is ejected 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 measurement history detailed information 90 displayed in the center of the measurement recording screen 72 takes as an example the sign determination of the current value abnormality by setting the sign 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 exceeds the sign upper limit value of 0.75 mA, naturally, the sign is 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。 A line selection button 84, a sign line selection button 86, and an abnormal line selection button 88 are arranged on the lower side of the measurement recording screen 72.

回線選択ボタン84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 84 is operated, the display can be 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。 The measurement record narrowing screen 92 of FIG. 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 closing button 112.

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 unit 94 selects from an up line and a down line. The device selection unit 96 selects from manual notification, fire hydrant, and 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。 On the measurement record narrowing screen 92, for example, when it is desired to narrow down to the measurement record of "section 01 in the manual notification device for the upstream line", as shown in the figure, the system selection unit 94 is "up line" and the device selection unit 96 is "up line". When "manual notification" and "01" are set in the section selection unit 98 and the confirmation button 102 is operated, the corresponding narrowing 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8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. Further, when the close button 112 is operated, the process 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 the function of the measurement record narrowing screen 92, the measurement records can be narrowed down and displayed by setting the narrowing conditions in combination with the system, the device, and the section from the huge number of stored measurement records. This makes it possible to efficiently determine, for example, 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.
