Particularly in recent years, the rainwater outflow rate tends to increase due to a decrease in the rainwater infiltration rate accompanying the urbanization of urban areas, and the importance of rainwater removal is increasing more and more.

決定する手法をとっていた。By the way, in a sewerage treatment facility, generally, rainwater that has flowed into a pipe is stored in a pump well, and the stored rainwater is extracted by a rainwater pump group and supplied to a rainwater treatment plant.
The operation control of the rainwater pump group is usually performed by controlling the number of pumps operating based on the water level in the pump well. In this control of the number of operating units, the water level in the pump well may change suddenly, so the amount of rainwater flowing into the pump well must be predicted and taken into consideration. Therefore, in conventional control,
In addition to the information on the rise and fall of the pump well water level, the operator decided the number of pumps to be operated based on the intuition and experience, taking into consideration the amount of rainfall in the jurisdiction.

転数制御を実現するまでに至っていない。In the operation control of the rainwater pump described above, the time lag from when the rainwater pump is started to when the rainwater pump actually starts operating is taken into consideration,
It is necessary to immediately determine the number of operating units according to fluctuations in pump well water level and rainfall. Moreover, in determining the operating pump, an optimum combination must be selected from a plurality of pumps having various discharge amounts. From such a background, a high level operation technique (intuition or experience) is required for the operation control of the rainwater pump. On the other hand, the rainwater pump facility is inferior to the training of operators because it is infrequently operated, and not only the rainwater flow characteristics are different at each sewage treatment plant, but also when the ground surface process and the connection of pipes are changed. Considering the change of the flow-down characteristics, not only the burden on the operator is heavy, but also the effective operation of the rainwater pump facility is limited.For example, not only the pump speed control based on the water level of the pump well but also the optimum speed It has not reached the point where control is realized.

る。Further, rainwater flows into the pump well after it passes through the pipes after rainfall, but it is necessary to quantitatively determine when and how much it will flow into the pump well. very hard. Therefore, when the amount of inflow to the pump well is reduced, the number of operating pumps tends to be increased.

Since it is controlled with a certain water level as the target value, the operating pump is operated at the minimum speed when the inflow to the pump well decreases. Therefore, the integrated pump operation time tends to be long.

The rainwater pump's target discharge rate is calculated based on the averaged rainfall obtained by measuring each time interval, multiplying the measured value by the occupied area ratio of the jurisdiction, and dividing the sum by the number of divided areas. The control method was adopted.

To get these controls right,
It is necessary to accurately grasp the rainwater flow-down situation and reflect it in the control. For example, by predicting the necessity of pump operation in operation control, it is possible to flexibly cope with sudden changes in the rainfall situation. That is, prior to this prediction, the jurisdiction area is divided into a plurality of areas that can be measured by a radar rain gauge in advance. Then, the radar rain gauge measures the amount of rainfall in each area at regular time intervals. In addition, the arrival time from each area to the conduit is measured in advance, and this is taken into consideration as the delay time when flowing into the pump well, and the rainfall in each area is measured by the radar rain gauge. Calculate the rainfall amount at each time by multiplying the occupation area ratio of each jurisdiction. Then, the total rainfall is divided by the number of divided areas to obtain the average rainfall. Based on this average rainfall, the pump group target discharge rate is calculated, and the rainwater pump operation is controlled.

区域数で除することにより平均化降雨量を求める。Further, instead of the radar rain gauge, the rain gauge is installed in each of the divided areas, and the rainfall quantity in each area is measured by each rain gauge. Then, as in the previous case, the amount of rainfall at each time is calculated by considering the arrival time from each area to the pipe as a delay time. The average rainfall is calculated by dividing the total amount of rainfall by the number of divided areas.

The amount of rainfall is output for each (D2). The downflow time T (i) from the farthest point of each mesh to the water level gauge 6 in the conduit 1 (calculated by the flow velocity at full pipe) and the occupied area ratio A (i) of the jurisdiction within each mesh are measured in advance.

Here, assuming that the time required to reach the rating after starting the pump is tp, if the pump is operated at this time, the rainwater inflow amount after tp hours can be dealt with. Therefore, the pump is started at t- (ti-tp). Let the level be the current activation level and the pump activation level at time t be the future activation level. In the setting of the startup pump flag, the case where the large pump or the small pump is stopped, or the case where the large pump or the small pump is started even if the pump is currently started is considered. With these features, flexible control according to the rainfall situation was made possible, and consideration was given so that sudden rainwater inflow could be dealt with.

The pump rotation speed corresponding to (t) is set (S10), and the operation amount of each pump is calculated and output (S11). In this way, by introducing fuzzy reasoning in addition to the calculation of the pump activation level, the experience and intuition of a skilled driver can be incorporated into the control, and especially the data used for the calculation (the antecedent part) is the rainfall amount and the pump well. This is advantageous in that it is data that the operator actually uses when operating the pump, such as the water level. In addition, even if the ground surface process or the connection of the conduit is changed, it can be easily dealt with by modifying the parameters used in the fuzzy inference.
