Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for discharging rainwater flowing into a pump well into a river by a group of rainwater pumps, and more particularly to a rainwater pump control device for controlling the start / stop timing and the number of rainwater pumps to be operated.

[0002]

2. Description of the Related Art Conventionally, in such a facility, generally,
The start / stop water level of the rainwater pump is set in advance, and the pump well water level is controlled by the set start / stop water level.

[0003]

However, in such conventional rainwater pump control, the start of the rainwater pump is delayed at the time of sudden rainfall, and there is a possibility that flood damage may occur. Further, in order to avoid such damage, it is necessary to perform manual operation by an operator during a sudden rainfall, which is a burden on the operator.

For this reason, in such rainwater pump control, there have been proposed several methods for reliably draining rainwater in response to sudden rainfall. As one of the methods,
A method has been proposed in which the start / stop water level of the rainwater pump is corrected by fuzzy calculation or the like using the pump well water level or the pump well water level change amount, and the pump well water level is controlled based on the corrected start / stop water level. . Alternatively,
A method has been proposed in which a pump that can be operated in the air is incorporated as a precedence standby pump, and the precedence standby pump is activated first at a certain starting water level.

[0005] However, of the above methods, the former method using fuzzy arithmetic or the like predicts the inflow of rainwater based on the rainfall measured by a rain gauge or the like, so that the rainwater inflow near the pump well is not considered. It is easy to overestimate rainfall conditions and to underestimate upstream conditions that have a significant effect on rainwater inflow to pump wells, and to accurately predict rainwater inflow depending on the characteristics of rainfall. There is a problem that can not be.

Further, in the latter method using the preceding standby type pump, since there is a difference between the starting water level and the water level at which water is actually discharged, the starting time of the preceding standby type pump becomes unnecessary depending on the characteristics of rainfall. There is a problem that it becomes longer and waste is likely to occur.

[0007] The present invention has been made in view of the above points, and an object of the present invention is to provide a rainwater pump control device capable of appropriately and economically controlling a rainwater pump group even in a sudden rainfall. I do.

Further, the rainwater pump control device 10 starts / stops the rainwater pump 2 calculated by the start / stop water level correction means 11.
It has a pump control means 15 that sends a start / stop command based on the stop water level and the pump well water level measured by the pump well water level gauge 3 to control the start / stop timing and the number of operating stormwater pumps 2. .

Among them, the start / stop water level correcting means 11
Has a weather mode determination unit 12 that determines the weather mode based on the rainfall measured by the rain gauge 4 and the main water level measured by the main water level gauge 5. The weather modes include a heavy rain mode and a heavy rain mode that promote the activation of the rainwater pump 2, a light rain mode that suppresses the activation of the rainwater pump 2, and a normal mode in which control is performed using a preset start / stop water level set value. It has two modes. These modes are determined based on the integrated value of the amount of rainfall for a certain period in the past and the main water level. For example, the heavy rain mode or the heavy rain mode is selected when both the pump well water level and the main water level are rising, and it is determined that there is a new inflow not only now but also in the future. On the other hand, the light rain mode is selected when the pump well water level is rising but the main water level is falling, and it is determined that there is no new inflow in the future.

In addition, the start / stop water level correction means 11 includes a plurality of fuzzy rule tables corresponding to heavy rain mode, heavy rain mode, light rain mode and normal mode based on the weather mode determined by the weather mode determination means 12.

Next, based on the weather mode determined by the weather mode determination means 12, the fuzzy operation means 13 of the start / stop water level correction means 11 corresponds to each of the heavy rain mode, heavy rain mode, light rain mode and normal mode. A plurality of fuzzy rule tables are switched, and a start / stop water level correction value of the rainwater pump 2 is obtained by fuzzy computation using a combination of the pump well water level and the pump well water level change amount using the switched fuzzy rule table. At this time, for example, when the weather mode is the heavy rain mode or the heavy rain mode, the starting water level correction value for lowering the starting water level is obtained, and the rainwater pump 2 is started earlier than usual. On the other hand, when the weather mode is the light rain mode, a starting water level correction value for increasing the starting water level is obtained, and the next started rainwater pump 2 is started with a delay.

Thereafter, the start / stop water level calculation means 14 of the start / stop water level correction means 11 causes the fuzzy calculation means 1 to operate.
The start / stop water level of the rainwater pump 2 is calculated by adding the start / stop water level correction value of the rainwater pump 2 obtained in step 3 to a preset start / stop water level set value of the rainwater pump 2.

Finally, the pump control means 15 starts the pump water based on the start / stop water level of the rainwater pump 2 calculated by the start / stop water level calculation means 14 and the pump well water level measured by the pump well water level gauge 3. A start / stop command is sent to control the start / stop timing and the number of operating rainwater pumps 2.
