The Automatic control system of polluted water treatment in paper- producing factory.
Abstract: This method of realization of processing dirty water is introduced. This design introduces to use the Programmable Logic Controller (PLC) realizes with industrial computer the design that automatic control system of polluted water treatment in paper-producing factory .The PLC passes with industry calculator the total line in RS-485 correspondence .The programmable preface controller has the high dependent, the programming is simple ,strong in interference etc in advantage ,so extensive apply to control of realm in industry ,but PLC is week in handing over with each other .On the other hand the industrial computer contains good man-machine interface and control decision abilities. The automatic control system of polluted water treatment in paper-producing factory design put together two kinds of knots, being completed by PLC to the direct control of the spot equipments, passing by a string of a total line corresponding with Industry computer .The operation results show that the system works very reliable and correct.
key words: PLC Processing dirty water control -system communication
