Problems solved by technology

[0004] The disadvantage of this control system is that if a link in the liquid level feedback mechanism or the drainage controller fails, even if the motor, water pump, water pump protection mechanism, etc. can operate normally, the entire system will not work.
System reliability is poor

Abstract

The invention relates to a modular redundancy control device for an electrical control system of an integrated sewage pump station, and belongs to the technical field of sewage treatment automatic control. According to the modular redundancy control device for the electrical control system of the integrated sewage pump station, even if main logic and feedback elements such as a drainage controllerand a liquid level sensor break down, a water pump can also be automatically started and stopped. The modular redundancy control device comprises a redundancy signal processing mechanism, a redundancy liquid level feedback mechanism, a redundancy configuration panel mechanism and a redundancy signal output mechanism, and is characterized in that the redundancy liquid level feedback mechanism is used for collecting liquid level signals and is connected with the redundancy signal processing mechanism; the redundancy configuration panel mechanism is used for collecting water pump setting information and is connected with the redundancy signal processing mechanism; and the redundancy signal output mechanism is connected with the redundancy signal processing mechanism and transmits redundancypump starting and stopping commands. During work, modules of all the mechanisms are combined to form the redundancy control device. The device has the beneficial effects of being simple in structure,low in cost, high in universality, high in reliability and the like.

Description

technical field [0001] The invention relates to a modular redundant control device for an electric control system of an integrated sewage pumping station, and belongs to the technical field of automatic control of sewage treatment. Background technique [0002] With the progress of society, water conservancy projects such as municipal rainwater, sewage pipe network, and water treatment plants are also developing in the direction of distribution. The integrated sewage pumping station has the advantages of short construction period and low cost in the new water treatment projects. Gradually rise. However, due to the electrical control system of the integrated pumping station, it cannot be placed indoors like a traditional pumping station, and it is also in an unattended state. In addition to the constraints of space, cost and other factors, its stability and reliability have become an urgent need for the industry. question. [0003] The existing control method mainly uses ...
