Studies On Distributed Computer Control System For Waste Water Disposal

The Distributed Computer Control System for Waste Water disposal with the research of disposal technics of waste water was introduced. The control system consists of computer PLC control system and local intelligent control instruments. The computer mainly realizes the functions of long-range supervision and management and it includes: dynamic show of technics flow, real time data acquirement and show, history data save and print, error alarm, etc; The PLC control system mainly accomplishes the technics flow control and harmonizes the logical relationship among local intelligent control instruments, and it will not only transmit the running states of local instruments to the computer ,but also receive the control commands from the computer; The local intelligent units take charge of the correlated parameter's inspect, process and control, and it will transmit the related parameters to the computer , etc.The design method of PLC control system, the integrated program development of computer the communication between PLC control system and computer was introduced, and the common design for local intelligent units was also discussed.This paper's purpose is to try to research the automation and intelligent for waste water disposal, and to provide some theory and technics for currently improvement of waste water disposal equipment new pattern waste water disposal equipment and design of control system. We hope it will improve the whole technics level of waste water disposal equipment for our country.
