Problems solved by technology

This method often starts drainage after the formation of waterlogging, and cannot respond in time
Some existing improved rainwater pumping station control systems can only allow pumping station managers to monitor the pumping station 24 hours a day and send control commands. The system cannot automatically control the operation of drainage pumps according to real-time rain conditions; The drainage pump is overloaded. When the drainage pump is working abnormally, the drainage pump cannot be found and shut down in time, which seriously shortens the service life of the drainage pump.

Embodiment 1

[0064] Please refer to figure 1 and figure 2 , figure 1 It is a flow chart of an optional implementation manner of the control method for the rainwater pumping station provided by the present invention; figure 2 It is a schematic diagram of an optional implementation manner of the control method for the rainwater pumping station provided by the present invention. This embodiment provides a control method for a drainage water pump station, which is applied to a control system for a drainage water pump station. The control system for a drainage water pump station includes a client, a server, a control terminal and a plurality of water pumps. The control method of the rainwater pumping station is to perform the following steps at every preset time unit:

[0065] Step S10: obtaining real-time water level height and rainfall intensity;

[0066] Step S11: obtaining a preset water level threshold;

[0067] Step S20: Input the water level height and rainfall intensity into the ...

Embodiment 2

[0080] This embodiment provides another optional control method for a rainwater drainage pump station. The running state includes start and stop, and step S50 includes:

[0081] Step S51: check the working record of the water pump, and read the running state of the water pump;

[0082] Step S52: when A>B, select the pump whose running state is stopped, read the accumulated working time, select the pump with the shortest accumulated working time, read the pump number, and send an opening command to the control terminal;

[0083] Step S53: when A

[0084] Step S54: Receive feedback information from the control terminal, update the work record and the number of pumps that have been turned on;

[0085] Step S55: Repeat steps S30 to S50.

[0086] Step S50 will be desc...

Embodiment 3

[0097] This embodiment provides another optional control method for a rainwater drainage pump station, the principle of which is basically the same as that of Embodiment 1, the difference is that the water pump has a working record, and the working record includes the pump number, the running state and the accumulated working time. The running state includes start and stop, and step S50 includes:

[0098] Step S56: Check the working record of the water pump, and read the running state of the water pump;

[0099] Step S57: when A>B, select the water pump whose running state is stopped, read the accumulated working hours, sort the accumulated working hours from short to long, read the numbers of the first A-B pumps, and send an opening command to the control terminal;

[0100] Step S58: when A<B, select the pump whose running state is on, read the accumulated working hours, sort the accumulated working hours from long to short, read the numbers of the first B-A pumps, and send a...

Abstract

The present invention provides a control method and control system for a rainwater pumping station. The rainwater pumping station control system includes a client, a server, a control terminal and a plurality of water pumps. The rainwater pumping station control method is applied to the rainwater pumping station control system. It includes the following steps: Step S10: Obtain the real-time water level height and real-time rainfall intensity; Step S20: Input the water level height and rainfall intensity into the analysis model to obtain the number of pre-opened water pumps; Step S30: Obtain the number of activated water pumps, and compare the number of pre-opened water pumps with The number of activated water pumps; step S40: the number of pre-activated water pumps is A, the number of activated water pumps is B, if A=B, then end this execution; step S50: if A≠B, control ∣A‑B∣ A water pump is turned on / off such that A=B. The invention automatically calculates the number of required water pumps by analyzing the real-time water level height and rainfall intensity, and automatically controls the operation of the rainwater pumping station to realize unattended operation.

Description

technical field [0001] The invention relates to the field of water pump control, in particular to a control method and a control system for a rainwater pump station. Background technique [0002] In rainy weather, the urban drainage system has undergone great tests. In many cities, due to the unreasonable planning of the drainage pipe network and the imperfect supporting facilities, the flood-prone points such as tunnels and low-lying road sections are prone to waterlogging, which seriously affects the smooth flow of traffic. will cause huge economic losses. [0003] The current treatment method is to build drainage pumping stations at these waterlogging-prone points. The drainage pumping stations are installed in low-lying urban road sections and suburban waterlogging-prone points to improve the drainage efficiency of pipeline rainwater and sewage and prevent urban waterlogging caused by rainstorms. The traditional rainwater drainage pump station starts the water pump at t...
