【正文】 ut on the CRT by good sketch type, print a necessary data in the meantime and be provided for lord to control and manager instruction produce. Supervise and control boundary but include the system total diagram, system cent diagram, imitate the quantity general chart, parameter a constitution, report to the police a window, history trend and register a window etc. boundary but. In the system total diagram, circulate the personnel can keep watch on signals, such as all movement appearances, equipments trouble and liquid which control an equipment and discharge etc. Operate a personnel in the system the cent the diagram can carry on a single machine point to move to circulate an operation to all control equipment, bee the set automatically circulate operation or the whole factories fullautomatic operation bine surveillance. In the meantime place of honor machine 2 and do a plait distance a machine. Medium control room to establish another an inset type emulation to hold, is been one control by the place of honor machine, in order to keep the craft process of the view manifestation whole factory and main parameter value.1. 2 The PLC stand According to wastewater treatment of two part, the spot the long range of the equipments the control output and the spot the signal collect to control a station pletion from two PLC wood native control station control the space grid, sewage promote a pump house, Pu spirit to sink sand pond39。 天津職業(yè)技術(shù)師范大學(xué)本科生畢業(yè)設(shè)計(jì) 英文資料與中文翻譯專業(yè)班級：自1003班學(xué)生姓名：王曉東指導(dǎo)教師：邴志剛 教授學(xué) 院：自動(dòng)化與電氣工程學(xué)院2014年6月Application of control system on the base of PLC in sewage treatmentThe 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 puter。s etc. to prepare a processing part. The PLC2 native control station controls dirty mire to dehydrate, press to filter machine etc. department..PLC3 native control station control SBR living creature processing part. Moreover, the on the spot native control station is each to establish an operation terminal to establish each, be responsible for at native to establish each control on the scene.(automatic control, order to move a control) The spot is each the physical parameter that the supervision order and include water level, temperature, discharge and turn soon, electric current39。 In the meantime, the PLC passes MB net upward the machine return to various data, place of honor machine logarithms according to carry on an operation processing, show various signal and print various statement.2 The design of PLC control program The system has four kinds of control methods: The native hand moves a control, single set equipments point moves a control, bee a set, the equipments automatically controls, the whole factory equipment fullautomatic control. Two kinds of ex with general methods at establish each adjust to try or maintain usage, the system is mainly circulate with fullautomatic control. Under this kind of way, all each kind of equipment from PLC according to in advance draw up of procedure auto control, don39。If fuse oxygen Gao while set upper limit, the frequency modulation breeze machine turns to soon lower 5%.So, carried out Pu spirit pond to provide automatically regulate of the amount of oxygen, since avoided unnecessary energy loss, again excellent turned movement craft.2. 2 The design of PLC program The adoptive plait distance software is a Concept 2. 2 XLs. Concept is according to under the Windows of the PLC plait distance tool, have good customer39。When fuse an oxygen value small at the 2 mgs/L, the breeze machine turns to soon rise 5%.If the breeze machine
