Description

本発明は、突然の浸水時における氾濫水の浸水深を正確に長期間連続的に測定でき、かつ予想浸水深の変化に対応できるセンサーと、当該センサーによる氾濫水の浸水深の測定方法に関する。   The present invention relates to a sensor capable of accurately and continuously measuring the inundation depth of flooded water during sudden inundation for a long period of time, and a method for measuring the inundation depth of flooded water using the sensor.

従来、水位を測定する水位計が検討されてきた。複数の電極を離間して直線上に配置した電極式検出器と、前記各電極からの信号をスキャニングして順次受け取り、前記電極式検出器の水位を検出する電極検出部と、前記電極式検出器の下端に設けられた水圧式検出器と、前記水圧式検出器からの信号を受けて水位を検出する圧力検出部と、前記水圧式検出器の水位を補正して真の水位を算出する演算装置を有する水圧式・電極式併用型水位測定装置が検討された（例えば、特許文献１参照）。更に、水中に投入設置する水位検出部の内部に、深さの順序にシフトレジスタ−を構成する順送り走査回路を内蔵し、かつ、当該水位検出部の深さの方向に多数の水位電極を並べると同時に当該多数の水位電極に対向する形に共通電極が設置され、当該水位電極を入力端として各水位電極と共通電極の間に流れる電流の値が所定のしきい値を越えるか否かによって前記シフトレジスタ−が駆動され、該シフトレジスタ−の出力で水位検出を行う多電極水位検出器が検討された（例えば、特許文献２参照）。   Conventionally, a water level gauge for measuring the water level has been studied. An electrode detector in which a plurality of electrodes are separated and arranged on a straight line, an electrode detector that sequentially receives signals from each electrode by scanning and detects the water level of the electrode detector, and the electrode detector A water pressure detector provided at the lower end of the vessel, a pressure detector that receives a signal from the water pressure detector and detects the water level, and corrects the water level of the water pressure detector to calculate the true water level. A hydraulic / electrode combined water level measuring device having an arithmetic unit has been studied (see, for example, Patent Document 1). Furthermore, a progressive scanning circuit that constitutes a shift register in the depth order is built in the water level detection unit that is placed in the water, and a large number of water level electrodes are arranged in the depth direction of the water level detection unit. At the same time, a common electrode is installed so as to face the many water level electrodes, and whether or not the value of the current flowing between each water level electrode and the common electrode with the water level electrode as an input terminal exceeds a predetermined threshold value. A multi-electrode water level detector in which the shift register is driven and the water level is detected by the output of the shift register has been studied (for example, see Patent Document 2).

最近、低地にある道路、アンダーパス部の道路凹地、地下室、地下駐車場、地下街、地下通路等の低地における浸水が、豪雨、台風等の自然現象によって突然発生し、道路規制等の緊急対策が間に合わず、走行中の車両が浸水に気づかずに浸水部に進入し、車両が水没して、運転手が死傷する事件、突然の浸水時に居合わせた人が避難できずに溺れる事件が各地で発生している。そこで、低地の突然の浸水時における氾濫水の浸水深を計測するセンサーの設置が検討された。しかし、被測定箇所に段差が存在し（例えば、車道と歩道）、安全上の理由から下段への前記センサーの設置が困難な場合、下段における氾濫水の浸水深は、上記水圧式・電極式併用型水位測定装置及び上記多電極水位検出器により計測できない。更に、被測定箇所の予想浸水深は幅広く、氾濫水の浸水深が大量生産された特定規格のセンサーにより計測できるとは限らない。従って、段差がある被測定箇所の突然の浸水時における氾濫水の浸水深を正確に長期間連続的に計測でき、かつ予想浸水深の変化に対応できるセンサーの開発が要求されている。しかしながら、このようなセンサーを提供する有効な手段は見出されていなかった。
特開平８−１４９８３号公報 特開平５−７９８８２号公報 Recently, inundation in lowlands such as roads in lowlands, road depressions in underpass areas, basements, underground parking lots, underground malls, underground passages, etc. has suddenly occurred due to natural phenomena such as heavy rain, typhoons, etc., and emergency measures such as road regulations have been taken There are incidents in various places where the running vehicle enters the flooded part without noticing the inundation, the vehicle is submerged, the driver is killed or injured, and the person who was present at the time of sudden flooding can not evacuate and drown is doing. Therefore, the installation of a sensor to measure the inundation depth of flooded water at the time of sudden inundation in the lowland was examined. However, if there is a step at the location to be measured (for example, a roadway and a sidewalk) and it is difficult to install the sensor on the lower stage for safety reasons, the inundation depth of the lower stage is determined by the hydraulic / electrode type. It cannot be measured by the combined water level measuring device and the multi-electrode water level detector. Further, the expected inundation depth of the measurement site is wide, and the inundation depth of the flood water cannot always be measured by a specific standard sensor that is mass-produced. Therefore, there is a demand for the development of a sensor capable of accurately measuring the flood water inundation depth at the time of sudden inundation at a measurement site with a step and continuously responding to changes in the expected inundation depth. However, no effective means for providing such a sensor has been found.

It is. Another problem to be solved by the present invention is to provide a method for measuring the inundation depth of flood water by the sensor.

本発明の発明者は、上記課題を解決するため、浸水深を計測するセンサーを鋭意検討し、水位電極が絶縁基板上に一定の間隔で設けられているユニット電極が電気的に接続されている構成のセンサーが有効であると見出し、本発明を完成させるに至った。   In order to solve the above problems, the inventor of the present invention has intensively studied a sensor for measuring the depth of water immersion, and unit electrodes in which water level electrodes are provided on the insulating substrate at regular intervals are electrically connected. The present inventors have found that the sensor of the configuration is effective and have completed the present invention.

本発明は、水位電極が絶縁基板上に一定の間隔で設けられているユニット電極と、前記ユニット電極に対向する共通電極と、電流が各水位電極と前記共通電極の間に流れる際、通電している水位電極の数に比例する電圧を出力する電流電圧変換回路を有し、複数の前記ユニット電極が電気的に接続されている、浸水深を計測する連結センサーである。
本発明の好ましい実施態様では、前記ユニット電極同士が接触している。
本発明の好ましい別の実施態様では、前記ユニット電極同士が接触していない。 The present invention provides a unit electrode in which water level electrodes are provided on an insulating substrate at regular intervals, a common electrode facing the unit electrode, and an electric current when current flows between each water level electrode and the common electrode. It is a connection sensor for measuring the depth of inundation, which has a current-voltage conversion circuit that outputs a voltage proportional to the number of water level electrodes, and is electrically connected to the plurality of unit electrodes.
In a preferred embodiment of the present invention, the unit electrodes are in contact with each other.
In another preferred embodiment of the present invention, the unit electrodes are not in contact with each other.

本発明は、被測定箇所が浸水していない場合、上記浸水深を計測する連結センサーで得られた情報が１日に１回送信され、被測定箇所が浸水している場合、前記情報が１日に１回以上の頻度で送信される、浸水深の測定方法である。   In the present invention, when the measurement site is not submerged, the information obtained by the connection sensor for measuring the submergence depth is transmitted once a day. When the measurement site is submerged, the information is 1 This is a method for measuring the depth of inundation transmitted at a frequency of once or more per day.

本発明の浸水深を計測する連結センサーは、水位電極が絶縁基板上に一定の間隔で設けられているユニット電極が電気的に接続されている構成を有しているから、電気的に接続されるユニット電極の数の調整により、予想浸水深の変化に対応できる。更に、本発明の浸水深を計測する連結センサーは、段差がある被測定箇所の各段毎にユニット電極の設置を可能ならしめ、各段毎の浸水深の測定を可能にする。しかも、本発明の浸水深を計測する連結センサーは、市販の乾電池を電源とし、頻繁な維持管理を必要としない。   The connection sensor for measuring the depth of inundation according to the present invention has a configuration in which unit electrodes in which the water level electrodes are provided on the insulating substrate at regular intervals are electrically connected. By adjusting the number of unit electrodes, it is possible to cope with changes in the expected inundation depth. Furthermore, the connection sensor for measuring the inundation depth according to the present invention makes it possible to install a unit electrode for each step of the measurement location with a step, and to measure the inundation depth for each step. And the connection sensor which measures the water immersion depth of this invention uses a commercially available dry cell as a power supply, and does not require frequent maintenance management.

図１は、本発明の浸水深を計測する連結センサーの１実施態様を示すブロック図である。本実施態様の連結センサーは、共通電極１、水位電極２、電流検出及びスイッチング回路、ラダー抵抗及び電流電圧変換回路を有している。２以上の水位電極２が、浸水の深さ方向に一定の間隔で並んでいる。共通電極１が、水位電極２に対向して設けられている。パルス電圧が共通電極１と水位電極２の間に一定の間隔で印加される。当該パルス電圧が被測定箇所の浸水時に印加されると、種々の物質が溶解している氾濫水は電気伝導性を有しているから、微小パルス電流が浸水した水位電極２と共通電極１の間に流れる。水位電極２に流れた微小パルス電流は、電流検出及びスイッチング回路で検出され、ラダー抵抗に流れていく。ラダー抵抗は並列に接続されている。   FIG. 1 is a block diagram showing an embodiment of a connection sensor for measuring a water immersion depth according to the present invention. The connection sensor of this embodiment has a common electrode 1, a water level electrode 2, a current detection and switching circuit, a ladder resistor, and a current-voltage conversion circuit. Two or more water level electrodes 2 are arranged at regular intervals in the depth direction of water immersion. A common electrode 1 is provided to face the water level electrode 2. A pulse voltage is applied between the common electrode 1 and the water level electrode 2 at regular intervals. When the pulse voltage is applied when the measurement target is flooded, the flood water in which various substances are dissolved has electrical conductivity. Therefore, the water level electrode 2 and the common electrode 1 in which a minute pulse current has been flooded Flowing in between. The minute pulse current that has flowed to the water level electrode 2 is detected by the current detection and switching circuit, and flows to the ladder resistor. Ladder resistors are connected in parallel.

図２は、電流検出及びスイッチング回路の詳細を示す回路図である。電圧が共通電極１に印加されると、微小電流が水を通して抵抗Ｒ５に流れる。半導体素子Ｑ２は電流検出回路（電流増幅回路）であり、微小電流を増幅し抵抗Ｒ３に充分な電流を流す。半導体素子Ｑ１はスイッチング回路であり、抵抗Ｒ５に流れる電流値に関わらず電流があるときオン、電流がないときオフとなる。前記スイッチング回路がオフのとき、電流は後段のラダー抵抗Ｒ６には流れず、前記スイッチング回路がオンのとき、ＶＣＣ（単位；Ｖ）／（ラダー抵抗Ｒ６の抵抗値Ｒ6＋抵抗Ｒ７の抵抗値Ｒ7）（単位；Ω）の電流が流れる。Ｒ6／ｎ＞＞Ｒ7であるとき、当該電流の値は常に一定である。図１に示される電流電圧変換回路のオペレーショナルアンプの＋入力側の電圧（Ｖｉｎ+）は、下記式（１）で示される。 FIG. 2 is a circuit diagram showing details of the current detection and switching circuit. When a voltage is applied to the common electrode 1, a minute current flows through the resistor R5 through water. The semiconductor element Q2 is a current detection circuit (current amplification circuit), which amplifies a minute current and allows a sufficient current to flow through the resistor R3. The semiconductor element Q1 is a switching circuit and is turned on when there is a current regardless of the value of the current flowing through the resistor R5 and turned off when there is no current. When the switching circuit is off, current does not flow through the ladder resistor R6 in the subsequent stage. When the switching circuit is on, VCC (unit: V) / (resistance value R 6 of the ladder resistor R6 + resistance value of the resistor R7) R 7 ) (unit: Ω) current flows. When R 6 / n >> R 7 , the current value is always constant. The voltage (Vin + ) on the + input side of the operational amplifier of the current-voltage conversion circuit shown in FIG. 1 is expressed by the following equation (1).

Ｖｉｎ+＝Ｖｃｃ×Ｒ7／（Ｒ6／ｎ＋Ｒ7） （１）
ここで、ｎは通電しているラダー抵抗の数、すなわち、浸水している水位電極２の数である。Ｒ6／ｎ＞＞Ｒ7であるとき、
Ｖｉｎ+≒ｎ×Ｖｃｃ×Ｒ7／Ｒ6 （２）
式（２）は、電流電圧変換回路からの出力電圧Ｖｏｕｔは、浸水している水位電極２の数に比例することを示している。従って、浸水深は、下記式（３）で求められる。
浸水深＝（浸水している水位電極２の数）×（水位電極２同士の距離） （３） Vin + = Vcc × R 7 / (R 6 / n + R 7 ) (1)
Here, n is the number of ladder resistors that are energized, that is, the number of water level electrodes 2 that are submerged. When R 6 / n >> R 7
Vin + ≈n × Vcc × R 7 / R 6 (2)
Equation (2) indicates that the output voltage Vout from the current-voltage conversion circuit is proportional to the number of submerged water level electrodes 2. Therefore, the water immersion depth is obtained by the following formula (3).
Inundation depth = (number of submerged water level electrodes 2) × (distance between water level electrodes 2) (3)
