Abstract

<P>PROBLEM TO BE SOLVED: To provide a tunnel ventilation control device and a control method capable of excluding a VI measured value transmitted from a VI measuring instrument without being incorporated into an arithmetic operation for calculating a ventilation quantity by detecting an abnormality when the VI measuring instrument causes a failure in software, and capable of excluding the VI measured value transmitted from the VI measuring instrument without being incorporated into the arithmetic operation for calculating the ventilation quantity by detecting reduction in accuracy even when accuracy reduction undeterminable by the VI measuring instrument itself is caused. <P>SOLUTION: The permeability of air in a tunnel is measured and stored in a data preserving part 23, and then, a VI gauge accuracy reduction determining part 24 determines whether or not the measured value read out of the data preserving part 23 is an abnormal value, and when determined as the abnormal value, a ventilation control arithmetic processing part 26 performs arithmetic processing for controlling ventilation by excluding the measured value being the abnormal value. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【０００１】
【発明の属する技術分野】
この発明は、例えばトンネル内の換気を行う複数の換気機器を制御する換気制御装置に係り、特に、一部の換気機器が故障した場合でも正常に換気制御を行うことができるトンネル換気制御装置および制御方法に関する。
【０００２】
【従来の技術】
従来、トンネル内の換気機器の制御を行う換気制御装置は、トンネル内の画像を撮影して、この画像の透過率を数値化したＶＩ計測値を求めるためのＶＩ計測器と、排風機や集塵機等の換気機器とを備えている。そして、計測されたＶＩ値および換気機器の台数等のデータを演算処理し、必要となる換気量を算出し、換気機器の制御を行っている。
【０００３】
ところで、ＶＩ計測器が機械（ハード）的に故障した場合、ＶＩ計測器は、当該ＶＩ計測器自身が故障を検知し、ＶＩ計測器が故障したことを示す故障信号を制御装置に送信する。換気制御装置は、この故障信号を受信すると、ＶＩ計測器からのＶＩ計測値を換気量を算出する演算には組み入れずに除外して、換気量を算出する演算を行う。また、トンネル内を浮遊する煤煙等などがＶＩ計測器のカメラに付着することによって測定精度が日々低下する。このため、ＶＩ計測器自身で計測制度の低下を判定し、測定値に補正をかける自動校正処理を行う。この自動校正処理が行われている場合は、自動校正処理信号を制御装置に送信し、この自動校正処理信号を受信すると、制御装置は、ＶＩ計測器からのＶＩ計測値を換気量を算出する演算には組み入れずに除外して、換気量を算出する演算を行う（例えば、特許文献１参照）。
【０００４】

特開２００１−８２０９７号。
【０００５】
【発明が解決しようとする課題】
ところが、このような構成では、ＶＩ計測器がハード的に故障した場合には、ＶＩ計測器自身が故障を検知するが、ＶＩ計測器がソフト的に故障した場合には、当該ＶＩ計測器自身では故障を検知できずに、換気制御装置に異常値であるＶＩ計測値を送信してしまう。さらに、自動校正を行う校正時間になる前に測定精度が低下してしまった場合は、正確な測定値が送信されない。従って、換気量の演算に必要なデータの内、ＶＩ計測値が正常なデータでないため、正確な換気機器への制御を行うことができない。また、各測定器ごとに校正処理を行っているため、精度判定処理等の各処理に必要なパラメータを有する必要がある。
【０００６】
この発明は上記事情に着目してなされたもので、その目的とするところは、ＶＩ計測器がソフト的に故障した場合にも異常を検知して、ＶＩ計測器から送信されるＶＩ計測値を換気量を算出する演算には組み入れずに除外でき、さらにＶＩ計測器自身で判定することのできない精度低下が起こった場合も、この精度低下を検知して、ＶＩ計測器から送信されるＶＩ計測値を換気量を算出する演算には組み入れずに除外できるトンネル換気制御装置および制御方法を提供することにある。
【０００７】
【課題を解決するための手段】
本発明はかかる課題を解決するものであり、請求項１の発明は、トンネル内の空気の透過率を測定し、測定された測定値を用いて演算処理を行い、演算処理された演算結果に応じて前記トンネル内に設定された換気機を運転制御するトンネル換気制御装置であって、トンネル内の空気の透過率を測定する測定手段と、前記測定手段によって測定された測定値を異常値か否かを判定する判定手段と、前記判定手段によって計測値が異常値であると判定された場合は、この異常値である測定値を除外して前記演算処理を行う演算手段とを備えたことを特徴とする。
【０００８】
したがって請求項１の発明は、トンネル内の空気の透過率が測定され、測定された測定値を異常値か否かが判定され、異常値であると判定された場合は、この異常値である測定値を除外して換気制御のための演算処理が行われる。このため、トンネル内の空気の透過率が測定された測定値が異常値である場合に、これを検出して異常値である測定値を除外して換気制御のための演算処理が行われるので、正常な測定値のみを用いて換気制御を行うことができる。
【０００９】
また請求項２の発明は、前記トンネル内の空気の透過率を測定し、測定値を求める複数の測定手段と、前記複数の測定手段によって測定されたそれぞれの測定値と、前記測定手段によって予め測定された平常値と、この平常値から前記測定値が逸脱する限度である第１の閾値と、前記複数の測定手段の内、隣接する２つの測定手段によって測定されたそれぞれの測定値同士の第１の差分値の理想値と、この理想値から前記第１の差分値が逸脱する限度である第２の閾値とを記憶する記憶手段と、前記測定値のそれぞれを前記平常値と比較して、複数の第２の差分値を求める第１の算出手段と、前記第１の算出手段によって算出された複数の第２の差分値の全体的な傾向を判定し、この傾向から逸脱している差分値を抽出する抽出手段と、前記抽出手段によって抽出された差分値と、前記記憶手段に記憶されている第１の閾値とを比較し、前記第１の閾値を超えているか否かを判定する第１の判定手段と、前記第１の判定手段によって、前記第１の閾値を超えていないと判定された場合は、前記複数の測定手段の内、隣接する２つの測定手段によって測定されたそれぞれの測定値同士を比較し、第１の差分値を求める第２の算出手段と、前記第２の算出手段によって算出された第１の差分値と、前記記憶手段に記憶されている理想値とを比較し、前記第２の閾値を超えているか否かを判定する第２の判定手段と、前記第１の判定手段によって第１の閾値を超えていると判定された場合は、前記第２の差分値を求めるために用いられた元データである測定値が異常値であると判定し、異常値であると判定された測定値を除外し、前記第２の判定手段によって第２の閾値を超えていると判定された場合は、前記隣接する２つの測定手段によって測定された各測定値が異常値であると判定し、異常値であると判定された測定値を除外し、これら除外された測定値以外の測定値を用いて演算処理を行う演算手段とを備えたことを特徴とする。
【００１０】
したがって請求項２の発明は、このトンネル内の空気の透過率が測定され、測定値が求められる。そして、求めされた複数の測定値と、予め測定された平常値と、この平常値から測定値が逸脱する限度である第１の閾値と、隣接する２つの測定手段によって測定されたそれぞれの測定値同士の第１の差分値の理想値と、この理想値から第１の差分値が逸脱する限度である第２の閾値とが記憶装置に記憶され、複数の測定値のそれぞれを平常値と比較され、複数の第２の差分値を求められ、算出された複数の第２の差分値の全体的な傾向が判定され、この傾向から逸脱している差分値が抽出される。抽出された差分値と、記憶装置に記憶されている第１の閾値とが比較され、第１の閾値を超えているか否かが判定される。第１の閾値を超えていないと判定された場合は、隣接する２つの測定手段によって測定されたそれぞれの測定値同士が比較され、第１の差分値が求められ、算出された第１の差分値と、記憶装置に記憶されている理想値とが比較され、第２の閾値を超えているか否かが判定される。第１の閾値を超えていると判定された場合は、第２の差分値を求めるために用いられた元データである測定値が異常値であると判定され、異常値であると判定された測定値が除外され、一方、第２の閾値を超えていると判定された場合は、隣接する２つの測定手段によって測定された各測定値が異常値であると判定され、異常値であると判定された測定値が除外され、これら除外された測定値以外の測定値を用いて演算処理が行われる。このため、隣接する測定手段で測定された測定値、およびすべての測定手段で測定された測定値と予め保持している理想値または閾値等とを比較判定することにより、測定手段自身で検出できない測定値の異常値を検出することでき、この異常値を除外して換気制御を行うことができる。
【００１１】
また請求項３の発明は、前記トンネル内の空気の透過率を測定し、測定値を求める複数の測定手段と、前記複数の測定手段の内、隣接する２つの測定手段によって測定されたそれぞれの測定値同士の差分値の理想値と、この理想値から前記差分値が逸脱する限度である閾値とを記憶する記憶手段と、前記複数の測定手段の内、隣接する２つの測定手段によって測定されたそれぞれの測定値同士を比較し、差分値を求める算出手段と、前記算出手段によって算出された差分値と、前記記憶手段に記憶されている理想値とを比較し、前記閾値を超えているか否かを判定する判定手段と、前記判定手段によって閾値を超えていると判定された場合は、前記隣接する２つの測定手段によって測定された各測定値が異常値であると判定し、異常値であると判定された測定値を除外して、前記複数の測定手段の内、前記隣接する２つの測定手段以外の測定手段によって測定された測定値を用いて演算処理を行う演算手段とを備えたことを特徴とする。
【００１２】
したがって請求項３の発明は、トンネル内の空気の透過率が測定され、測定値が求められ、複数の測定手段の内、隣接する２つの測定手段によって測定されたそれぞれの測定値同士の差分値の理想値と、この理想値から前記差分値が逸脱する限度である閾値とが記憶装置に記憶される。そして、複数の測定手段の内、隣接する２つの測定手段によって測定されたそれぞれの測定値同士が比較され、差分値が求められ、算出された差分値と、記憶装置に記憶されている理想値とが比較され、閾値を超えているか否かが判定される。閾値を超えていると判定された場合は、隣接する２つの測定手段によって測定された各測定値が異常値であると判定され、異常値であると判定された測定値を除外して、複数の測定手段の内、隣接する２つの測定手段以外の測定手段によって測定された測定値が用られ演算処理が行われる。このため、隣接する測定手段で測定された測定値と予め保持している閾値とを比較判定することにより、測定手段自身で検出できない測定値の異常値を検出することでき、この異常値を除外して換気制御を行うことができる。
【００１３】
また請求項４の発明は、トンネル内の空気の透過率を測定し、測定値を求める複数の測定手段と、前記複数の測定手段によって測定されたそれぞれの測定値と、前記測定手段によって予め測定された平常値と、この平常値から前記測定値が逸脱する限度である閾値とを記憶する記憶手段と、前記測定値のそれぞれを前記平常値と比較して、複数の差分値を求める算出手段と、前記算出手段によって算出された複数の差分値の全体的な傾向を判定し、この傾向から逸脱している差分値を抽出する抽出手段と、前記抽出手段によって抽出された差分値と、前記記憶手段に記憶されている閾値とを比較し、前記閾値を超えているか否かを判定する判定手段と、前記判定手段によって閾値を超えていると判定された場合は、前記差分値を求めるために用いられた元データである測定値が異常値であると判定し、異常値であると判定された測定値を除外して、除外された前記測定値以外の複数の測定値を用いて演算処理を行う演算手段とを備えたことを特徴とする。
【００１４】
したがって請求項４発明は、トンネル内の空気の透過率が測定され、測定値が求められ、測定された複数の測定値と、測定手段によって予め測定された平常値と、この平常値から測定値が逸脱する限度である閾値とが記憶装置に記憶される。そして、複数の測定値のそれぞれが平常値と比較され、複数の差分値が求められ、算出された複数の差分値の全体的な傾向が判定され、この傾向から逸脱している差分値が抽出される。抽出された差分値と、記憶装置に記憶されている閾値とが比較され、閾値を超えているか否かが判定される。閾値を超えていると判定された場合は、差分値を求めるために用いられた元データである測定値が異常値であると判定され、異常値であると判定された測定値が除外され、除外された測定値以外の測定値が用いられ演算処理が行われる。このため、すべての測定手段で測定された測定値と予め保持している理想値とを比較判定することにより、測定手段自身で検出できない測定値の異常値を検出することでき、この異常値を除外して換気制御を行うことができる。
【００１５】
また請求項５の発明は、さらに、前記記憶手段は判定継続時間情報を有しており、前記判定手段によって、前記閾値を超えていると判定された場合は、前記判定継続時間情報に基づいて判定継続時間を検出する検出手段と、前記検出手段によって前記判定手段の判定継続時間が前記継続時間情報以内であると判定された場合は、該当する測定値が正常値であると判定し、正常値であると判定された測定値を用いて演算処理を行う演算手段とを備えたことを特徴とする。
【００１６】
したがって請求項５の発明は、閾値を超えていると判定された場合は、判定継続時間情報に基づいて判定継続時間が検出され、継続時間情報以内であると判定された場合は、該当する測定値が正常値であると判定され、正常値であると判定された測定値を用いて演算処理が行われる。このため、単位時間でサンプリングされたデータだけの比較判定ではわからないトンネル内の透過率低下に対応できる。
【００１７】
また本発明の請求項６は請求項１の方法のカテゴリに該当する請求項であり、請求項１と同様の効果を奏する。
【００１８】
【発明の実施の形態】
（第１の実施形態）
図１は、この発明に係わるトンネル換気制御方法を適用したトンネル換気制御装置を用いたトンネル換気制御システムの一実施形態を示す模式図である。
【００１９】
トンネル換気制御システムは、少なくとも例えば、道路トンネル１０内の換気制御を行う換気制御装置１と、この換気制御装置１に接続され、道路トンネル１０内の視環境（どれだけ見通せるか）を計測する煙霧透過率計（以下、ＶＩ計と称す）２と、換気制御装置１に接続され、道路トンネル１０内の車両等の交通量の計測を行う交通量計測装置３と、換気制御装置１に接続され、ファンの回転によって道路トンネル１０内の空気を換気するためのジェットファン（以下、ＪＦと称す）４と、換気制御装置１に接続され、道路トンネル１０内の空気を外部に排出するための立抗送排風機５と、換気制御装置１に接続され、車両等の排気ガス等を収集するための集塵機６とから構成されている。なお、ＶＩ計２は、トンネル１０内に例えば一定間隔で配置されているものとする。
【００２０】
次に図２は、この発明に係わるトンネル換気制御方法を適用したトンネル換気制御装置１の一実施形態を示すブロック図である。トンネル換気制御装置１は、ＶＩ計２、交通量計測装置３、ＪＦ４、立抗送排風機５および集塵機６からのデータの入出力を行うデータ入出力部２１と、各ＶＩ計２から送信されてくる測定値のサンプリング処理を行うサンプリング処理部２２と、ＶＩ計２から受信した計測値、隣接する２つのＶＩ計２から計測された計測値同士の差分値の理想値、この理想値から差分値が逸脱している値の限界値である判定基準値（閾値）、および判定を行う継続時間を定めている判定継続時間情報等を保存しているデータ保存部２３と、ＶＩ計２の計測精度の低下を判定するＶＩ計精度低下判定処理部２４と、判定基準値に基づいてＶＩ計２が計測した計測値が異常値であると判定された場合、およびＶＩ計２が自動校正処理中であることを示す自動校正処理信号（後述）をＶＩ計２から受信した場合、またはＶＩ計２が機械（ハード）的に故障した際にＶＩ計２自身が故障を検知し、ＶＩ計２が故障したことを示す故障信号をＶＩ計２から受信した場合、またはＶＩ計２が測定値に補正をかける自動校正処理を行い、自動校正処理信号をＶＩ計２から受信した場合に、受信した測定値を換気量を求める演算から除外する処理を行うＶＩ計除外処理部２５と、交通量の車両台数の情報および、ＶＩ計除外処理部２５で除外されなかった計測値を用いて換気量の演算を行う換気制御演算処理部２６と、換気制御演算処理部２６の演算結果に基づいてＪＦ４、立抗送排風機５および集塵機６等の換気機器の制御を行う制御信号を出力する換気機器制御出力部２７とを少なくとも備える。なお、判定基準値は、隣接する２つのＶＩ計２から計測された計測値同士の差分値の理想値から差分値が逸脱している値の限界値である以外に、計測されたＶＩ値全体の傾向からどれだけ逸脱しているかを規定する値としても使用される。
【００２１】
次に図３は、ＶＩ計精度低下判定処理部２４の構成を示したブロック図である。ＶＩ計精度低下判定処理部２４は、ＶＩ計の精度低下判定処理（後述）の制御を行う制御部２４ａと、各種データの入出力等を行う通信部２４ｂと、データ保存部２３に保存しているサンプリングデータの取り出し、所定のデータの抽出等を行い、測定値とサンプリングデータとを比較して差分値を算出するデータ算出部２４ｃと、理想値から差分値が逸脱している値が、判定基準値を超えているか否か等を判定するデータ判定部２４ｄとを少なくとも備える。
【００２２】
次に図４は、ＶＩ計精度低下判定処理部２４の処理を示したフローチャートである。ＶＩ計精度低下判定処理部２４の処理を図２および図４を参照して説明する。ＶＩ計精度低下判定処理部２４は、ステップＳ１で、サンプリングデータであるＶＩ計２によって測定された測定値（ＶＩ値）、交通量計測装置３から送信されてくるトンネル１０内の通行車両台数情報および通行車両に占める大型車の混入率情報、ＪＦ４から送信されてくる稼働している当該ＪＦ４の運転台数情報、立抗送排風機５から送信されてくる稼働している当該立抗送排風機５の運転台数情報、および集塵機６から送信されてくる稼働している当該集塵機６の運転台数情報を換気量の演算のためのデータとしてデータ保存部２３に入力・保存する。
【００２３】
ＶＩ計精度低下判定処理部２４のデータ算出部２４ｃは、ステップＳ２で、データ保存部２３に保存されている測定されたサンプリングデータを取り出す（読み出す）。このときの取り出されたデータとしては、例えば、同一時間帯である前日の０時台または１時台等の１時間当たりのデータである。そして、ＶＩ計精度低下判定処理部２４のデータ算出部２４ｃは、ステップＳ３で、取り出されたサンプリングデータから、例えば、車両台数情報、大型車混入率情報、および換気機器の運転台数情報等が現在計測されている各情報の値（現在値）と最も近似している単位時間のデータを抽出する。ＶＩ計精度低下判定処理部２４のデータ算出部２４ｃは、ステップＳ４で、すべてのＶＩ値に対して抽出されたデータと比較を行い、差分値（ＶＩ差分値）を算出する。ＶＩ計精度低下判定処理部２４のデータ判定部２４ｄは、ステップＳ５で、算出された複数のＶＩ差分値に基づいて、全体ＶＩ差分値判定を行う。具体的には、ＶＩ差分値の全体の傾向としてマイナスの値である場合に、プラスの値である場合等で、全体の傾向とは異なる値であると判定される場合で、かつ、そのＶＩ差分値が予め設定された判定基準値を超えている場合には、ＶＩ計の精度の低下の可能性があると判定し、ステップＳ７に遷移する。
【００２４】
一方、ステップＳ５で、ＶＩ計精度低下判定処理部２４のデータ判定部２４ｄが判定基準値内であると判定した場合は、ＶＩ計精度低下判定処理部２４のデータ判定部２４ｄは、ステップＳ６で、隣接するＶＩ計が測定したＶＩ値同士を比較し、ステップＳ５と同様に、予め設定された判定基準値を超えているかを判定する。判定基準値を超えている場合には、同様にＶＩ計の精度の低下の可能性があると判定し、ステップＳ７に遷移する。一方、ステップＳ６で、ＶＩ計精度低下判定処理部２４のデータ判定部２４ｄが判定基準値内であると判定した場合は、計測されたＶＩ値は正常値であると判定され、ＶＩ計精度低下判定処理部２４から出力される。
【００２５】
また、ＶＩ計精度低下判定処理部２４のデータ判定部２４ｄは、ステップＳ７で、予め設定された判定継続時間情報をデータ保存部２３から読み出し、この判定継続時間情報に基づいた継続時間を超過すると精度の低下の可能性があると判定され、ステップＳ８に遷移し、ＶＩ計除外処理部２５に精度低下ＶＩ計として通知する。ステップＳ７で、ＶＩ計精度低下判定処理部２４のデータ判定部２４ｄが継続時間を超過していないと判定した場合は、計測されたＶＩ値は正常値であると判定され、ＶＩ計精度低下判定処理部２４から出力される。なお、ステップＳ７で、ＶＩ計精度低下判定処理部２４のデータ判定部２４ｄによって継続時間を判定する理由は、単位時間でサンプリングされたデータだけの比較判定では、例えば整備不良車や大型車群が短時間にトンネル内を通過することによって、実際にトンネル内のＶＩが低下している場合などには対応できないためである。
【００２６】
以上の構成より、ＶＩ計測器がソフト的に故障した場合に異常を検知して、ＶＩ計測器から送信されるＶＩ計測値を換気量を算出する演算には組み入れずに除外でき、さらにＶＩ計測器自身で判定することのできない精度低下が起こった場合もＶＩ計測器から送信されるＶＩ計測値を換気量を算出する演算には組み入れずに除外できるため、精度の高い換気制御を行うことができる。
【００２７】
（その他の実施形態）
また、本発明の第１の実施形態では、全体ＶＩ差分値判定を行った後に、隣接するＶＩ計が計測したＶＩ値同士のＶＩ差分値判定を行うが、隣接するＶＩ計が計測したＶＩ値同士のＶＩ差分値判定を行った後に、全体ＶＩ差分値判定を行うようにしてもよい。また、経過時間判定を行わないこともできる。その他、全体ＶＩ差分値判断だけの実施形態や、隣接するＶＩ計が計測したＶＩ値同士のＶＩ差分値判定だけの実施形態でもよく、任意にＶＩ差分値判定を行うことができ、この発明の要旨を逸脱しない範囲で種々変形して実施できることは勿論である。
【００２８】
【発明の効果】
以上詳述したようにこの発明では、トンネル内の空気の透過率を測定し、測定した測定値を異常値か否かを判定し、異常値であると判定した場合は、この異常値である測定値を除外して換気制御のための演算処理を行う。
【００２９】
したがってこの発明によれば、ＶＩ計測器がソフト的に故障した場合に異常を検知して、ＶＩ計測器から送信されるＶＩ計測値を換気量を算出する演算には組み入れずに除外でき、さらにＶＩ計測器自身で判定することのできない精度低下が起こった場合もＶＩ計測器から送信されるＶＩ計測値を換気量を算出する演算には組み入れずに除外できるため、精度の高い換気制御を行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a ventilation control device that controls, for example, a plurality of ventilation devices that perform ventilation in a tunnel, and in particular, a tunnel ventilation control device that can perform ventilation control normally even when some ventilation devices break down, and It relates to a control method.
[0002]
[Prior art]
Conventionally, a ventilation control device that controls ventilation equipment in a tunnel takes an image inside the tunnel, and obtains a VI measurement value obtained by quantifying the transmittance of the image, and a ventilator and a dust collector. And other ventilation equipment. Then, the data such as the measured VI value and the number of ventilation devices are processed, the necessary ventilation volume is calculated, and the ventilation devices are controlled.
[0003]
By the way, when the VI measuring instrument fails mechanically (hardware), the VI measuring instrument detects the failure, and transmits a failure signal indicating that the VI measuring instrument has failed to the control device. When receiving the failure signal, the ventilation control device performs an operation for calculating the ventilation amount by excluding the VI measurement value from the VI measuring instrument without being included in the calculation for calculating the ventilation amount. In addition, the measurement accuracy decreases every day due to smoke and the like floating in the tunnel adhering to the camera of the VI measuring instrument. For this reason, the VI measuring instrument itself determines a decrease in the measurement system and performs an automatic calibration process for correcting the measured value. When this automatic calibration processing is performed, the automatic calibration processing signal is transmitted to the control device, and when this automatic calibration processing signal is received, the control device calculates the ventilation volume based on the VI measurement value from the VI measuring instrument. A calculation for calculating the ventilation volume is performed without including the calculation in the calculation (see, for example, Patent Document 1).

[Problems to be solved by the invention]
However, in such a configuration, when the VI measuring instrument fails in hardware, the VI measuring instrument itself detects the failure. However, when the VI measuring instrument fails in software, the VI measuring instrument itself Then, the failure cannot be detected, and the VI measurement value that is an abnormal value is transmitted to the ventilation control device. Furthermore, if the measurement accuracy is reduced before the calibration time for performing automatic calibration, an accurate measurement value is not transmitted. Therefore, since the VI measurement value is not normal data among the data necessary for calculating the ventilation amount, it is not possible to accurately control the ventilation device. In addition, since calibration processing is performed for each measuring instrument, it is necessary to have parameters necessary for each processing such as accuracy determination processing.
[0006]
The present invention has been made paying attention to the above circumstances, and the object of the present invention is to detect an abnormality even when a VI measuring instrument is broken down in software and to detect a VI measured value transmitted from the VI measuring instrument. VI measurement that can be excluded without being included in the calculation to calculate the ventilation volume, and when the accuracy degradation that cannot be determined by the VI instrument itself has occurred, is detected and this VI measurement is sent from the VI instrument The object is to provide a tunnel ventilation control device and a control method in which values can be excluded without being included in a calculation for calculating a ventilation amount.
[0007]
[Means for Solving the Problems]
The present invention solves this problem, and the invention of claim 1 measures the air permeability in the tunnel, performs arithmetic processing using the measured values, and calculates the arithmetic processing results. A tunnel ventilation control device for controlling the operation of a ventilator set in the tunnel according to the measurement means for measuring the air permeability in the tunnel and whether the measurement value measured by the measurement means is an abnormal value. Determination means for determining whether or not and when the determination means determines that the measurement value is an abnormal value, the calculation means excludes the measurement value that is the abnormal value and performs the calculation processing It is characterized by.
[0008]
Therefore, in the invention of claim 1, the air permeability in the tunnel is measured, it is determined whether or not the measured value is an abnormal value, and if it is determined to be an abnormal value, this is the abnormal value. The calculation process for ventilation control is performed excluding the measured value. For this reason, when the measured value of the air permeability measured in the tunnel is an abnormal value, this is detected and the measured value that is the abnormal value is excluded, and calculation processing for ventilation control is performed. Ventilation control can be performed using only normal measurement values.
[0009]
According to a second aspect of the present invention, there is provided a plurality of measurement means for measuring the air permeability in the tunnel and obtaining measurement values, the respective measurement values measured by the plurality of measurement means, and the measurement means in advance. A measured normal value, a first threshold that is a limit that the measured value deviates from the normal value, and each measured value measured by two adjacent measuring means among the plurality of measuring means. A storage means for storing an ideal value of the first difference value and a second threshold value that is a limit for deviating the first difference value from the ideal value, and comparing each of the measured values with the normal value. A first calculating means for obtaining a plurality of second difference values and an overall tendency of the plurality of second difference values calculated by the first calculating means, and deviating from this tendency Extracting means for extracting the difference value, A first determination unit that compares the difference value extracted by the output unit with a first threshold value stored in the storage unit and determines whether or not the first threshold value is exceeded; If it is determined by the first determination means that the first threshold value is not exceeded, the measured values measured by the two adjacent measurement means among the plurality of measurement means are compared, A second calculation unit that obtains a difference value of 1, a first difference value calculated by the second calculation unit, and an ideal value stored in the storage unit; Used to determine the second difference value when it is determined by the first determination means that the second threshold value exceeds the first threshold value. The measured value, which is the original data, is determined to be an abnormal value. If the measurement value determined to be a value is excluded and it is determined by the second determination means that the second threshold value is exceeded, each measurement value measured by the two adjacent measurement means is It is characterized by comprising an arithmetic means for determining that the measured value is an abnormal value, excluding the measured value determined to be an abnormal value, and performing a calculation process using a measured value other than the excluded measured value. .

Connected to a permeability meter (hereinafter referred to as a VI meter) 2 and a ventilation control device 1, connected to the traffic control device 3 for measuring the traffic volume of a vehicle or the like in the road tunnel 10, and the ventilation control device 1. , A jet fan (hereinafter referred to as JF) 4 for ventilating the air in the road tunnel 10 by rotation of the fan, and a ventilation control device 1, and a stand for discharging the air in the road tunnel 10 to the outside. It is comprised from the anti-air supply / exhaust device 5 and the dust collector 6 which is connected to the ventilation control apparatus 1 and collects exhaust gas etc., such as a vehicle. Note that the VI meter 2 is arranged in the tunnel 10 at regular intervals, for example.
[0020]
Next, FIG. 2 is a block diagram showing an embodiment of a tunnel ventilation control device 1 to which the tunnel ventilation control method according to the present invention is applied. The tunnel ventilation control device 1 is transmitted from the VI meter 2, the traffic volume measuring device 3, the JF 4, the data input / output unit 21 for inputting / outputting data from the resistance air sending / exhaust device 5 and the dust collector 6, and each VI meter 2. Sampling processing unit 22 that performs sampling processing of incoming measurement values, measured values received from VI meter 2, ideal values of differences between measured values measured from two adjacent VI meters 2, and differences from these ideal values A data storage unit 23 that stores a determination reference value (threshold value) that is a limit value of a value that deviates from a value, determination duration information that determines a duration for performing the determination, and the measurement by the VI meter 2 The VI meter accuracy decrease determination processing unit 24 that determines a decrease in accuracy, and when it is determined that the measured value measured by the VI meter 2 based on the determination reference value is an abnormal value, and the VI meter 2 is in the automatic calibration process Automatic school showing that When a processing signal (described later) is received from the VI meter 2, or when the VI meter 2 has failed mechanically (hardware), the VI meter 2 itself detects the failure and indicates a failure signal indicating that the VI meter 2 has failed. Is calculated from the VI meter 2 or when the VI meter 2 performs an automatic calibration process to correct the measured value and an automatic calibration process signal is received from the VI meter 2, the received measured value is calculated to obtain the ventilation volume. VI-exclusion processing unit 25 that performs processing to be excluded from the vehicle, and a ventilation control arithmetic processing unit that calculates ventilation volume using information on the number of vehicles in the traffic volume and measured values that are not excluded by the VI-meter exclusion processing unit 25 26 and a ventilator control output unit 27 that outputs a control signal for controlling ventilators such as the JF 4, the resistance air supply / exhaust fan 5 and the dust collector 6 based on the calculation result of the ventilation control calculation processing unit 26. Note that the determination reference value is the entire measured VI value other than the limit value of the value where the difference value deviates from the ideal value of the difference value between the measurement values measured from two adjacent VI meters 2. It is also used as a value that defines how far the trend deviates.
[0021]
Next, FIG. 3 is a block diagram showing a configuration of the VI meter accuracy decrease determination processing unit 24. The VI meter accuracy decrease determination processing unit 24 stores the control in the VI meter accuracy decrease determination process (described later), the communication unit 24b that inputs and outputs various data, and the data storage unit 23. Data sampling unit 24c that extracts a sampling data, extracts predetermined data, and compares the measured value with the sampling data to calculate a difference value, and determines whether the difference value deviates from the ideal value. And a data determination unit 24d for determining whether or not the reference value is exceeded.
[0022]
Next, FIG. 4 is a flowchart showing the processing of the VI meter accuracy decrease determination processing unit 24. The processing of the VI meter accuracy decrease determination processing unit 24 will be described with reference to FIGS. In step S 1, the VI meter accuracy deterioration determination processing unit 24 measures the measured value (VI value) measured by the VI meter 2 as sampling data, and the number of passing vehicles in the tunnel 10 transmitted from the traffic measuring device 3. And the mixing ratio information of large vehicles in the passing vehicle, the operating number information of the operating JF 4 transmitted from the JF 4, and the counter-responding exhaust fan operating from the counter-responding exhaust fan 5 The number of operating units 5 and the number of operating units of the operating dust collector 6 transmitted from the dust collector 6 are input and stored in the data storage unit 23 as data for calculating the ventilation amount.
[0023]
In step S2, the data calculation unit 24c of the VI meter accuracy deterioration determination processing unit 24 extracts (reads) the measured sampling data stored in the data storage unit 23. The data extracted at this time is, for example, data per hour such as the 0:00 or 1 o'clock of the previous day in the same time zone. Then, in step S3, the data calculation unit 24c of the VI meter accuracy deterioration determination processing unit 24 presents, for example, the vehicle number information, the large vehicle mixing rate information, and the number of operating ventilation device information from the extracted sampling data. Data of unit time that is closest to the value of each piece of information being measured (current value) is extracted. In step S4, the data calculation unit 24c of the VI meter accuracy decrease determination processing unit 24 compares the extracted data with respect to all VI values, and calculates a difference value (VI difference value). In step S5, the data determination unit 24d of the VI meter accuracy decrease determination processing unit 24 performs overall VI difference value determination based on the plurality of calculated VI difference values. Specifically, when the overall tendency of the VI difference value is a negative value, when it is a positive value, etc., it is determined that the value is different from the overall trend, and the VI If the difference value exceeds the preset determination reference value, it is determined that there is a possibility that the accuracy of the VI meter is lowered, and the process proceeds to step S7.
[0024]
On the other hand, if it is determined in step S5 that the data determination unit 24d of the VI meter accuracy decrease determination processing unit 24 is within the determination reference value, the data determination unit 24d of the VI meter accuracy decrease determination processing unit 24 determines in step S6. Then, the VI values measured by the adjacent VI meters are compared with each other, and it is determined whether or not a predetermined criterion value is exceeded as in step S5. When it exceeds the determination reference value, it is similarly determined that there is a possibility that the accuracy of the VI meter is lowered, and the process proceeds to step S7. On the other hand, if the data determination unit 24d of the VI meter accuracy decrease determination processing unit 24 determines that it is within the determination reference value in step S6, the measured VI value is determined to be a normal value, and the VI meter accuracy decreases. Output from the determination processing unit 24.
[0025]
Further, in step S7, the data determination unit 24d of the VI meter accuracy decrease determination processing unit 24 reads the preset determination duration information from the data storage unit 23, and if the duration based on the determination duration information is exceeded. It is determined that there is a possibility of a decrease in accuracy, the process proceeds to step S8, and the VI meter exclusion processing unit 25 is notified as a decreased accuracy VI meter. In step S7, when the data determination unit 24d of the VI meter accuracy decrease determination processing unit 24 determines that the duration has not been exceeded, it is determined that the measured VI value is a normal value, and the VI meter accuracy decrease determination Output from the processing unit 24. In step S7, the reason for determining the duration by the data determination unit 24d of the VI meter accuracy decrease determination processing unit 24 is that, for example, in a comparative determination of only data sampled in unit time, a poorly maintained vehicle or a large vehicle group, for example, This is because it is impossible to cope with a case where the VI in the tunnel is actually lowered by passing through the tunnel in a short time.
[0026]
With the above configuration, when a VI instrument breaks down in software, an abnormality is detected, and the VI measurement value transmitted from the VI instrument can be excluded without being included in the calculation for calculating the ventilation volume. Since the VI measurement value transmitted from the VI measuring instrument can be excluded without being included in the calculation for calculating the ventilation volume even when the accuracy deterioration that cannot be determined by the instrument itself can be excluded, highly accurate ventilation control can be performed. it can.
[0027]
(Other embodiments)
In the first embodiment of the present invention, the VI difference value determination between VI values measured by the adjacent VI meters is performed after the overall VI difference value determination, but the VI value measured by the adjacent VI meter is determined. After performing VI difference value determination between each other, overall VI difference value determination may be performed. It is also possible not to perform elapsed time determination. In addition, an embodiment in which only the entire VI difference value is determined or an embodiment in which only the VI difference value is determined between the VI values measured by the adjacent VI meters may be used, and VI difference value determination can be arbitrarily performed. Of course, various modifications can be made without departing from the scope of the invention.
[0028]
【The invention's effect】
As described above in detail, in the present invention, the air permeability in the tunnel is measured, it is determined whether or not the measured value is an abnormal value, and if it is determined to be an abnormal value, this is the abnormal value. Exclude the measured value and perform the calculation process for ventilation control.
[0029]
Therefore, according to the present invention, it is possible to detect an abnormality when the VI measuring instrument breaks down in software, and exclude the VI measurement value transmitted from the VI measuring instrument without being included in the calculation for calculating the ventilation amount. Since the VI measurement value transmitted from the VI measuring instrument can be excluded without being included in the calculation for calculating the ventilation volume even when the accuracy degradation cannot be determined by the VI measuring instrument itself, highly accurate ventilation control is performed. be able to.
