【正文】 cording to fuse oxygen of average value to control breeze machine to turn fuse oxygen low limit at the bottom of the enactment, the frequency modulation breeze machine turns to soon increase 5%。s etc. imitate quantity, from to in response to of an appearance spread a feeling machine or change to send to a machine examination to e out and change into the electric current signal of the 4~20 mA, through shield inside the PLC that the electric cable sends to each statures system, from the PLC picks up a people through various mold piece sample telemunication , imitate quantity control the signal send to performance organization by the 4~20 mA electric current form after being output by the PLC, control performance organization of action. The Modicon Quantum series PLC of Schneider pany is satisfy liberal of, according to standard of work conjunction and the spot total line conjunction etc. application the technique provided various work a choice, support Modbus, Modbus Plus(MB+), the long range I/0, TCP/IP etc. work conjunction, have stronger and , the wastewater treatment is convenient to arrive of the PLC choose the series of Modicon Ouantum of use Schneider. 1. 3 Correspondences MB+agreement is the Modicon pany release of an open type of the adoption IEEE802. 4 correspond by letter 5 agreements the spot total line of card +the work together other works pare to have a set of simple, the investment be little, work speed quick, correspondence the stability strong etc. characteristics, it make calculator, controller and other data sources through an usage double wring line or fiber optic cable Be a body to together carry on correspondence at the whole work the CPU mold piece of the Modicon Quantum series PLC imply MB+correspondence, therefore correspond by letter a work to choose to use MB+ control two machine, two control stations with native PLC of room to pass MB+the work link PLC CPU mold piece passes MB+correspondence and two machines carry on data mutation and collect the place of honor supervision various operation instruction of the system and the spot the examination signal and data, through analysis handle, pass exportation mold piece to control object output control signal。 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 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 online follow with offline imitate the Concept of true function 2. 2 XL of honor machine and of the PLC adoption set the be quickly simple and circulate speed, correspond by letter the stability strong MB+ 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 and international many wastewater treatment factorieses adopted a modern forerunner to control technique and calculator technique and constitute calculator direct, control thus, manage system excellent to turn the programmable logic controller(PLC) then take microprocessor as the calculator technique automatically controls technique and correspondence technique but develops of a kind of new and in general use utomatic control structure simple, function superior, dependable sex Gao, work properly words in general use, be easy to plait distance, usage convenience etc. advantage etc..The silver Chuan City the first wastewater treatment factory adopted a SBR craft and take PLC
