Description

【0001】
【発明の属する技術分野】
本発明は、道路等の地表に積もった雪を地下水により消雪するための消雪ポンプ制御システムに関するものである。
【0002】
【従来の技術】
道路等の地表に積もった雪の従来の消雪方法としては、積雪箇所に地下水等を電動ポンプで汲み上げて、道路下に配設した配管に送り込み、配管に設けた噴水ノズルから噴出させて散水する方法が一般的である。散水の開始と停止は、通常、降雪計測器の出力信号に基づいて電動ポンプをオンオフ制御することにより行われている。すなわち、降雪計測器が所定量以上の降雪を検知したら手動により又は自動的に電動ポンプをオンにし、消雪の必要がなくなったら電動ポンプをオフにする。その際、積雪量の多小に関わりなく十分に消雪できるように、電動ポンプの運転は常に100%出力で行っている。
【0003】
【発明が解決しようとする課題】
しかしながら、従来の消雪ポンプ制御システムでは、積雪量の多少に関わりなく、電動ポンプの運転を常に100%出力で行う関係上、積雪が少ない場合は、必要以上の水量を使用し、地下水及び電力を無駄に消費してしまうことになる。その結果、冬期、降雪地帯では道路の消雪のために膨大な量の地下水を必要以上に汲み上げることになり、それが原因で地盤沈下という重大な環境問題を引き起こすという問題点があった。
【0004】
それに対しては、降雪計測器が検知した降雪量に基づいて電動ポンプの回転制御を行い、積雪量に応じた水量だけを散水する消雪システムが考えられる。そのようにすれば、地下水及び電力を無駄に消費してしまうことがなくなる可能性がある。しかしながら、降雪量に応じて電動ポンプを制御しても、水源である地下水井戸の水位は、常に一定に保持されるわけではなく、地下水位の変化のため、電動ポンプにより散水される水量は、必ずしも電動ポンプの回転速度に対応しなくなるとの問題点がある。
【0005】
例えば、12月の雪の降り始めの時期には、地下水位が高くなっていて所定のポンプ回転速度で所定の散水量が得られるが、消雪のため地下水を汲み上げていくにしたがって地下水位が低下していき、1,2月になって雪の最盛期になると、降雪量に対応した回転速度で電動ポンプを運転しても、地下水位低下が原因で所定の散水量が得られず、十分な消雪ができなくなって、交通等に支障が生じてしまうとの問題点がある。
【0006】
また、降雪量と電動ポンプによる水の吐出圧力又は放水量とに基づいて電動ポンプの回転速度を決めても、気温,雪温,風力,風向,道路通行量等の他の外部条件によっては、消雪効果に差ができて散水量が不足したり余分になったりしてしまうとの問題点がある。
【0007】
本発明は、上記のような問題点に鑑み、降雪量と電動ポンプからの水の吐出圧力又は放水量とに応じて地下水を散水することにより、消雪を確実に行うことが出来、かつ、地下水の使用量を必要最小限にして地盤沈下を防止できるようにすることを目的とするものである。さらに、降雪量と電動ポンプの吐出圧力又は放水量以外の気温,雪温,風力,風向,道路通行量等の外部条件に基づいて散水量を微調整することにより、一層きめ細かな消雪制御を可能とすることを目的とするものである。
【0008】
【課題を解決するための手段】
前記課題を解決するため、請求項1に記載の消雪ポンプ制御システムは、地下水を汲み上げる電動ポンプと、該電動ポンプに接続される消雪用のパイプと、前記電動ポンプから前記消雪用のパイプに放水される水の吐出圧力又は放水量を計測する水計測装置と、降雪量を計測する降雪計測装置と、降雪量と電動ポンプの吐出圧力又は放水量とを対応づけたテーブルと、前記降雪量計測器及び水計測装置の各計測値と前記テーブルとに基づいて前記電動ポンプを制御する制御装置とを備えたことを特徴とする。このようにすると、降雪量と電動ポンプからの水の吐出圧力又は放水量とに応じて地下水を散水することにより、消雪を確実に行うことが出来、かつ、地下水の使用量を必要最小限にして地盤沈下を防止できる。
【0009】
また、請求項2に記載の消雪ポンプ制御システムは、地下水を汲み上げる電動ポンプと、該電動ポンプに接続される消雪用のパイプと、前記電動ポンプから前記消雪用のパイプに放水される水の吐出圧力又は放水量を計測する水計測装置と、降雪量を計測する降雪計測装置と、降雪量と電動ポンプの吐出圧力又は放水量とを対応づけたテーブルと、前記降雪量と前記水の吐出圧力又は放水量以外の外部条件に基づいて前記テーブルの吐出圧力又は放水量を補正する補正装置と、前記降雪量計測器及び水計測装置の各計測値と前記テーブルとに基づいて前記電動ポンプを制御する制御装置とを備えたことを特徴とする。このようにすると、降雪量と電動ポンプの吐出圧力又は放水量以外の気温,雪温,風力,風向,道路通行量等の外部条件に基づいて散水量を微調整することにより、消雪を確実に行うことが出来、かつ、地下水による散水の制御をするにあたり、一層きめ細かな消雪制御が可能となる。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて詳細に説明する。
図1は、本発明の消雪ポンプ制御システムの一例を示す図である。図1において、1は井戸、2は電動ポンプ、3はパイプ、4は噴水ノズル、5はポンプ制御盤、6は降雪量計測器、7は流量計、8は道路、9は側溝である。
【0011】
井戸1は、50〜60mもの深さまで掘られており、その中に電動ポンプ2が入れられている。冬期になって道路8に雪が積もったら、電動ポンプ2を運転して地下水を汲み上げ、道路8の下に配設されているパイプ3を通して噴水ノズル4から噴出させて道路8に積もった雪に散水して融かし、融かした水は側溝9を通して排水される。電動ポンプ2は、ポンプ制御盤5内のインバータにより駆動され、道路8の積雪状況に応じた水量を散水できる回転速度になるように制御される。
【0012】
降雪量計測器6は、所定の開口面積を有する容器で受けた雪を一旦融かし、その水分量を測って降雪量を計測するタイプのものを用いることができ、電動ポンプ2は、降雪量計測器6により計測された降雪量に基づいて制御される。ただ、単に降雪量に対応させて電動ポンプ2の回転速度を決めると、井戸1の地下水が所定の水位を維持していればよいが、地下水の使いすぎ等により、井戸1の水位が低下してしまうと、同じポンプ回転速度にしても、所定の流量が得られず、水量不足で所定の消雪効果が得られなくなる。
【0013】
そこで、本発明の消雪ポンプ制御システムでは、電動ポンプ2の出口側に流量計7を設け、それにより電動ポンプ2の吐出水量を計測し、その計測値をポンプ制御盤5にフィードバックして、降雪量計測器6により計測された降雪量に対応させて、電動ポンプ2の吐出水量が井戸1の水位に関わりなく所定の値になるように制御する。
【0014】
図2は、本発明の消雪ポンプ制御システムの制御ブロック図である。符号2,6,7は、図1のものに対応しており、10は、ポンプ制御盤5の内部に配設されたポンプ制御装置、11,12は外部監視所、13はインターネット網である。ポンプ制御装置10は、降雪量計測器6によって計測された単位時間当たりの降雪量と電動ポンプ2からパイプ3に放水されるべき流量とを対応づけた制御用のテーブルを保持している。
【0015】
制御用のテーブルでは、例えば、降雪量Sに対して流量F、降雪量Sに対して流量F、・・・というように設定されている。そして、降雪量計測器6によって降雪量Sが計測されたら、ポンプ制御装置10は、流量Fになるように、電動ポンプからの水の吐出圧力又は放水量を計測しつつ、電動ポンプ2を制御し、降雪量Sが計測されたら、同様に、流量Fになるように制御する。そのようにすれば、井戸1の地下水位の高低に関わりなく消雪に必要かつ十分な設定された水量を散水できる。
【0016】
ところで、制御用のテーブルで設定する流量は、降雪量に比例して増やせば良さそうに思われるが、必ずしもそのような関係にはならず、また、消雪ポンプ制御システムを設置する道路は、長さ,幅,通行量等が様々で制御用のテーブルを一律には設定できず、ある道路区間で採用し、良好な結果が得られた制御用のテーブルでも、別の道路区間には適用できない。
【0017】
そこで、この消雪ポンプ制御システムでは、ポンプ制御装置10をインターネット網13に接続するとともに、道路の各所にカメラ付きの外部監視所11,12を設置して道路の状況を監視し、インターネット網13を介して道路の消雪状況をポンプ制御装置10に通知するようにしている。すなわち、外部監視所11,12では、道路8上の積雪状態をカメラで見て、散水が不十分な場合や多すぎる場合は、どの程度不十分か、あるいは多すぎるかを散水の過不足情報としてポンプ制御装置10に通知する。
【0018】
ポンプ制御装置10は、外部監視所11,12から散水の過不足情報を受け取ったら、その時の降雪量計測器6の計測値とともに、時系列的に保持しておく。そして、一定期間のデータが蓄積されたら、蓄積されたデータに基づいて上記制御用のテーブルの流量を補正する。そのようにすれば、当該道路8の最適な消雪制御を、さらにきめ細かに行うことが可能になる。
【0019】
なお、上記実施形態では、流量計7により電動ポンプ2出口の流量を計測してフィードバックするようにしたが、一般に、流量計は高価である。そこで、流量計7の代わりに、比較的安価な圧力計測器を用いて電動ポンプ2出口の吐出圧力を計測し、その計測値をポンプ制御装置10にフィードバックするようにし、降雪量に応じて所定の吐出圧力が得られるように制御してもよい。
【0020】
また、上記実施形態では、道路の長さ,幅,通行量等の道路状況に応じて制御用のテーブルを補正する場合を示したが、降雪量以外に気温,雪温,風力,風向等も計測し、それらの計測値を使って制御用のテーブルを補正するようにしてもよい。そのようにすれば、より適正な消雪制御が可能になる。
【0021】
【発明の効果】
本発明は、以上説明したように構成されているので、次に記載するような効果を奏する。
すなわち、請求項1に記載の消雪ポンプ制御システムは、降雪量と電動ポンプの吐出圧力又は放水量とを対応づけたテーブルを持たせ、降雪量計測器の計測値及び電動ポンプから消雪用のパイプに放水される水の吐出圧力又は放水量を計測する水計測装置の計測値と前記テーブルとに基づいて電動ポンプを制御するようにして、井戸の水位の上下に関わらず降雪量に見合った水量を吐出させるようにした。その結果、降雪量と電動ポンプからの水の吐出圧力又は放水量とに応じて地下水を散水することにより、消雪を確実に行うことが出来、かつ、地下水の使用量を必要最小限にして地盤沈下を防止できる。
【0022】
また、請求項2に記載の消雪ポンプ制御システムは、降雪量以外の外部条件に基づいて前記テーブルの吐出圧力又は放水量を補正する補正装置を付加したので、降雪量と電動ポンプの吐出圧力又は放水量以外の気温,雪温,風力,風向,道路通行量等の外部条件に基づいて散水量を微調整することにより、消雪を確実に行うことが出来、かつ、地下水による散水の制御をするにあたり、一層きめ細かな消雪制御が可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a snow removal pump control system for removing snow accumulated on the surface of a road or the like by groundwater.
[0002]
[Prior art]
As a conventional method for removing snow accumulated on the surface of roads and other surfaces, groundwater is pumped to the snow-covered area with an electric pump, sent to pipes arranged under the road, and spouted from fountain nozzles provided on the pipes. The method of doing is general. The start and stop of watering are usually performed by controlling the electric pump on / off based on an output signal of a snowfall measuring instrument. That is, the electric pump is turned on manually or automatically when the snowfall measuring device detects a predetermined amount of snowfall or more, and the electric pump is turned off when it becomes unnecessary to remove the snow. At that time, the operation of the electric pump is always performed at 100% output so that the snow can be sufficiently eliminated regardless of the amount of snow.
[0003]
[Problems to be solved by the invention]
However, in the conventional snow removal pump control system, the operation of the electric pump is always performed at 100% power regardless of the amount of snow. Will be wasted. As a result, in the snowfall area in winter, a huge amount of groundwater is pumped more than necessary for snow removal on the road, which causes a serious environmental problem of land subsidence.
[0004]
In response to this, a snow removal system that controls the rotation of the electric pump based on the amount of snowfall detected by the snowfall measuring instrument and sprays only water in accordance with the amount of snowfall can be considered. By doing so, there is a possibility that groundwater and electric power will not be wasted. However, even if the electric pump is controlled according to the amount of snowfall, the water level of the groundwater well, which is the water source, is not always kept constant. There is a problem that it does not always correspond to the rotation speed of the electric pump.
[0005]
For example, at the beginning of snowfall in December, the groundwater level is high and a predetermined watering rate can be obtained at a predetermined pump rotation speed, but as the groundwater is pumped up for snow removal, the groundwater level rises. In the peak season of snow in January and February, even if the electric pump is operated at a rotation speed corresponding to the amount of snowfall, a predetermined amount of water cannot be obtained due to a decrease in groundwater level, There is a problem in that sufficient snow removal cannot be performed, thereby causing troubles in traffic and the like.
[0006]
Even if the rotation speed of the electric pump is determined based on the amount of snowfall and the discharge pressure or the amount of water discharged by the electric pump, depending on other external conditions such as temperature, snow temperature, wind power, wind direction, and road traffic, There is a problem that the amount of water spray is insufficient or extra due to a difference in the snow removal effect.
[0007]
The present invention, in view of the above problems, by spraying groundwater according to the amount of snowfall and the discharge pressure or the amount of water discharged from the electric pump, snow can be reliably removed, and, The purpose is to minimize the amount of groundwater used to prevent land subsidence. Furthermore, by finely adjusting the amount of water spray based on the snowfall and the external conditions such as temperature, snow temperature, wind power, wind direction, road traffic, etc. other than the discharge pressure of the electric pump or the amount of water discharged, more fine snowfall control can be achieved. The purpose is to make it possible.
[0008]
[Means for Solving the Problems]
In order to solve the problem, the snow removal pump control system according to claim 1 includes an electric pump that pumps groundwater, a pipe for snow removal connected to the electric pump, and a pump for snow removal from the electric pump. A water measuring device that measures the discharge pressure or the amount of water discharged to the pipe, a snowfall measuring device that measures the amount of snowfall, a table that associates the amount of snowfall with the discharge pressure or amount of water discharged from the electric pump, A control device for controlling the electric pump based on the measured values of the snowfall measuring device and the water measuring device and the table is provided. In this way, by sprinkling groundwater in accordance with the amount of snowfall and the discharge pressure or amount of water discharged from the electric pump, it is possible to reliably perform snow removal and minimize the amount of groundwater used. To prevent land subsidence.
[0009]
Further, the snow removal pump control system according to claim 2 discharges water from the electric pump for pumping groundwater, a pipe for snow removal connected to the electric pump, and the pipe for snow removal from the electric pump. A water measuring device for measuring a water discharge pressure or a water discharge amount, a snowfall measuring device for measuring a snowfall amount, a table in which a snowfall amount is associated with a discharge pressure or a water discharge amount of an electric pump, and the snowfall amount and the water amount. A correction device that corrects the discharge pressure or water discharge amount of the table based on external conditions other than the discharge pressure or water discharge amount, and the electric motor based on the measured values of the snowfall amount measuring device and the water measuring device and the table. A control device for controlling the pump. In this way, the amount of water spray can be finely adjusted based on the snowfall and external conditions such as temperature, snow temperature, wind, wind direction, and road traffic other than the discharge pressure or water discharge of the electric pump, so that the snow removal can be ensured. In controlling water sprinkling by groundwater, more detailed snow-melting control is possible.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram illustrating an example of a snow removal pump control system according to the present invention. In FIG. 1, 1 is a well, 2 is an electric pump, 3 is a pipe, 4 is a fountain nozzle, 5 is a pump control panel, 6 is a snowfall measuring instrument, 7 is a flow meter, 8 is a road, and 9 is a gutter.
[0011]
The well 1 is dug to a depth of 50 to 60 m, in which an electric pump 2 is placed. In winter, when snow accumulates on the road 8, the electric pump 2 is operated to pump up the groundwater, and is spouted from the fountain nozzle 4 through the pipe 3 provided under the road 8 to spray water on the snow accumulated on the road 8. The molten water is drained through the gutter 9. The electric pump 2 is driven by an inverter in the pump control panel 5 and is controlled so as to have a rotation speed at which water can be sprinkled according to the snow condition on the road 8.
[0012]
The snowfall amount measuring device 6 may be of a type that once melts snow received in a container having a predetermined opening area and measures the amount of water to measure the amount of snowfall. It is controlled based on the amount of snowfall measured by the amount measuring device 6. However, if the rotation speed of the electric pump 2 is simply determined according to the amount of snowfall, it is sufficient that the groundwater in the well 1 keeps a predetermined water level. Therefore, even if the pump rotation speed is the same, a predetermined flow rate cannot be obtained, and a predetermined snow removal effect cannot be obtained due to a shortage of water.
[0013]
Therefore, in the snow removal pump control system of the present invention, a flow meter 7 is provided at the outlet side of the electric pump 2 to measure the amount of water discharged from the electric pump 2, and the measured value is fed back to the pump control panel 5, In accordance with the amount of snowfall measured by the snowfall measuring device 6, the discharge amount of the electric pump 2 is controlled to be a predetermined value regardless of the water level of the well 1.
[0014]
FIG. 2 is a control block diagram of the snow removal pump control system of the present invention. Reference numerals 2, 6, and 7 correspond to those in FIG. 1, 10 is a pump control device disposed inside the pump control panel 5, 11 and 12 are external monitoring stations, and 13 is an Internet network. . The pump control device 10 holds a control table in which the amount of snowfall per unit time measured by the snowfall amount measuring device 6 is associated with the amount of water to be discharged from the electric pump 2 to the pipe 3.
[0015]
The control of the table, for example, the flow rate F 1 with respect to snowfall S 1, the flow rate F 2 against snowfall S 2, are set such that,. Then, after snowfall S 1 is measured by the snowfall measuring instrument 6, the pump control device 10, so that the flow rate F 1, while measuring the discharge pressure or discharge water amount of water from the electric pump, the electric pump 2 controls Once snowfall S 2 is measured, likewise, is controlled to be in the flow F 2. By doing so, a set amount of water necessary and sufficient for snow removal can be sprinkled regardless of the level of the groundwater level of the well 1.
[0016]
By the way, it seems good to increase the flow rate set in the control table in proportion to the amount of snowfall, but it does not always have such a relationship, and the road on which the snow removal pump control system is installed is The control table cannot be set uniformly because of various lengths, widths, traffic volumes, etc. It is adopted in a certain road section, and even a control table with good results can be applied to another road section. Can not.
[0017]
Therefore, in this snow removal pump control system, the pump control device 10 is connected to the Internet 13 and external monitoring stations 11 and 12 with cameras are installed at various places on the road to monitor the state of the road. Is notified to the pump control device 10 of the snow removal situation on the road via the. That is, the external monitoring stations 11 and 12 monitor the snow condition on the road 8 with a camera, and when watering is insufficient or too much, determine whether the watering is insufficient or too much. To the pump control device 10.
[0018]
When the pump control device 10 receives the information on excess or deficiency of watering from the external monitoring stations 11 and 12, the pump control device 10 retains the measured value of the snowfall amount measuring device 6 at that time in time series. Then, when data for a certain period is accumulated, the flow rate of the control table is corrected based on the accumulated data. By doing so, it is possible to perform the optimum snow removal control on the road 8 more finely.
[0019]
In the above embodiment, the flow rate at the outlet of the electric pump 2 is measured by the flow meter 7 and fed back, but the flow meter is generally expensive. Thus, instead of the flow meter 7, the discharge pressure at the outlet of the electric pump 2 is measured using a relatively inexpensive pressure measuring device, and the measured value is fed back to the pump control device 10, so that a predetermined value is determined according to the amount of snowfall. May be controlled so as to obtain the discharge pressure.
[0020]
Further, in the above-described embodiment, the case where the control table is corrected according to the road condition such as the length, width, and traffic amount of the road has been described. Measurement may be performed, and the control table may be corrected using the measured values. By doing so, more appropriate snow removal control becomes possible.
[0021]
【The invention's effect】
The present invention is configured as described above, and has the following effects.
In other words, the snow removal pump control system according to claim 1 has a table in which the snowfall amount and the discharge pressure or the water discharge amount of the electric pump are associated with each other. The electric pump is controlled based on the measurement value of the water measuring device that measures the discharge pressure or the amount of water discharged to the pipe of the pipe and the table, so as to match the snowfall regardless of the water level of the well. The discharged amount of water was discharged. As a result, by spraying groundwater in accordance with the amount of snowfall and the discharge pressure or amount of water discharged from the electric pump, it is possible to reliably perform snow removal, and to minimize the amount of groundwater used. Land subsidence can be prevented.
[0022]
Further, the snow removal pump control system according to claim 2 further includes a correction device for correcting the discharge pressure or the water discharge amount of the table based on an external condition other than the snowfall amount, so that the snowfall amount and the discharge pressure of the electric pump are added. Or, by finely adjusting the amount of watering based on external conditions such as temperature, snow temperature, wind power, wind direction, road traffic, etc. other than the amount of water discharge, snow removal can be performed reliably, and watering by groundwater can be controlled. In doing so, more detailed snow removal control becomes possible.
