Application of control system on the base of PLC in

sewage treatment

The paper introduces a distributed control system of sewage treatment, and the core of the system is PLC. The structure of the control system, the assignment and implementation of the tasks, the control scheme and the design concept of program are expounded. The way of central monitoring management and dispersing control is used by the control system; the long一distance control and monitoring of field equipment are uncharged of the upper computer; the software program of designs uses Intouch7. 0. The specific technology, equipment, the controlling of main parameter and several running data are uncharged of the PLC stations, and the software program of designs uses Concept 2. 2XL with online tracking and outline simulating. MB+ net is adopted by the communication between the upper computer and the PLC stations, with its simply building net, quickly running and stable communication. The automatic control of PLC has been successfully completed in sewage treatment, which has improved the operation efficiency and management level of sewage treatment equipment

Introduced to take PLC as the distribute type control system of core in the wastewater treatment system of apply。Concretely described the structure, mission of the control system an allotment and carry out, the way of control and the thought of the program design.The way controled the concentration monitor of the system adoption a management and scattered a control, the place of honor machine be responsible for the spot the long range of the equipments control and surveillance, software adoption Intouch7. 0 draw up.The PLC native station is responsible for to the concrete craft, equipments and is mainly controled parameter to carry on control and collect various movement data, the program design adoption have on-line follow with off-line imitate the Concept of true function 2. 2 XL software.Place of honor machine and of the PLC adoption set the net be quickly simple and circulate speed, correspond by letter the stability strong MB+net.The whole control system successfully solved the PLC controls a problem in the automation within wastewater treatment and raised a wastewater treatment equipments to circulate an efficiency and manage level.

Recently, for carrying out high quality, low consume, stable dependable movement.Domestic and international many wastewater treatment factorieses adopted a modern forerunner to control technique and calculator technique and constitute calculator direct, control thus, manage system.Make system excellent to turn movement.But the programmable logic controller(PLC) then take microprocessor as
