Automatic control system of industrial sewage disposal
Abstract: Have introduced basic principle and thought that the automatic control system of industrial sewage disposal is designed, have narrated the implementation method that the automatically controlled course and system in industry's sewage disposal system are implemented, and to using the programmable controller to realize that has done detailed description in control of each course of sewage disposal and composition of the control system. In addition can programme controller have dependability high , programming simple , anti-interference a series of advantages such as being better, so apply to the industry controlled field extensively, and because the PC has better man- machine interface and controls decision ability , let PLC and PC through communication , RS422/485 of bus , , make PLC function in human-computer interaction performance strengthen greatly. The automatic control system of industrial sewage disposal this time has nowadays been designed and reached modern automation standardization, technicalization, three requests of humanization pursued, making should have very strong dependability , maintenance and intelligent systematically.
