Sewage treatment electronic control system based on SOPC technique

Abstract

The invention relates to a sewage treatment electronic control system based on SOPC technique, consisting of a CPU mainboard module, a plurality of subboard IO expansion relays, a plurality of subboard IO expansion modules and a dipolar private bus. The CPU mainboard module realizes bidirectional connection with the plurality of subboard IO expansion relays through the private bus; and each subboard IO expansion relay realizes bidirectional connection with the plurality of subboard IO expansion modules through the private bus. The invention has strong reliability, ensures strong functional expandability and upgradability by adopting an FPGA structure described by hardware, achieves hundreds of thousands of controllable digital amount I/O interfaces and analog amount I/O interfaces of a controller for users to expand easily, and overcomes the defect of low I/O cost performance of general programmable controllers.

Description

[0001] Field: [0002] The invention relates to a special electric control system for sewage treatment, in particular to an electric control system for sewage treatment based on SOPC technology. Background technique: [0003] The main problems in the operation of the sewage treatment electric control system are: the capacity of the sewage tanks such as the regulating pool, the hydrolysis acidification pool, the intermediate pool, and the CAST reaction pool is large, and the electric control system cannot be powered off all the year round. Even if the production is interrupted during holidays, the sewage treatment cannot be interrupted. , This puts a lot of pressure on the electronic control system, especially the central controller, that is, the CPU of the programmable controller. Generally, after 5 to 6 years of continuous operation, failures such as crashes are prone to occur, resulting in control failure of the sewage treatment station. Cause sewage to overflow and pollute ...
