Sewage pump station monitoring system

Abstract

The level meter of this sewage pumping station monitoring system accesses PLC through the simulated volume input module, and PLC links with electric valves of different water pumps and electric switches of grating machines through the output module. The pump outlet is installed with the flow meter linking PLC. PLC reads the level data on real time, and starts or closes one or multiple pumps when reaching the set level, which initiates the pumps on sequence and the sequence regular rotation, and starts up the delay dislocation sequence when starting multiple pumps. According to the set time, PLC starts and stops grating machine regularly. PLC connects the server computer, and transmits the operating data of equipment, which can be started and stop manually without the impact of level. The server computer remotely connects the monitoring system computer, transmitting the operation data and alarming when abnormity happens.

Description

(1) Technical field [0001] The invention relates to the field of computer automatic control, in particular to a sewage pumping station monitoring system. (2) Technical background [0002] The sewage pool of the sewage pumping station is equipped with 3 to 5 water pumps and 1 grille machine. In the past, manual guarding was required. Because the amount of sewage inflow changes from time to time, it is necessary to determine the number of pumps to be turned on according to the water level of the sewage pool, and the grill machine in the sewage pool also needs to be started regularly. During the following torrential rain, the sewage flow rate can increase several times. If the pump cannot be turned on in time, the sewage will overflow and cause an accident. On the contrary, if the sewage flow rate decreases and the water level in the sewage pool drops, the pump is not turned off in time. If the water level drops below the suction port of the pump, the suction pipe will dry out...

AI Technical Summary

Problems solved by technology

During the following torrential rain, the sewage flow rate can increase several times. If the pump cannot be started in time, the sewage will overflow and cause accidents.

On the contrary, when the sewage flow rate decreases and the water level in the sewage pool drops, the pump is not turned off in time. If the water level drops below the suction port of the pump, the suction pipe will dry out, which will cause excessive current and burn out the pump.

There are multiple sewage pumping stations in the city, and management personnel are required to manage each pumping station, and they need to be on duty all day long, with a heavy workload

And it is difficult to centrally control the operation of all pump stations

In particular, the environment in the sewage pumping station is harsh and the smell is pungent, so it is not suitable for people to work on duty for a long time

[0003] In addition, the running time and power consumption of each pump in the sewage pumping station cannot be recorded, stored, queried, and counted.
