    The Software Design of TPC Craft Sewage Disposai System

ABSTRACT:This article has introduced the design of TPC sewage disposal craft computer control system’s software, The whole software system include monitoring and control system of upper-computer and PLC (programmable controller ) control program of downer-computer. This system includes two parts,the upper-computer and the downer-computer. The upper-computer adoptsPC, and the downer-computer adopts the programmable controller (PLC ) of S7-200 series produced by Siemens Company , makes use of method controlled in VB and serial communication of RS-232 to realize the communication between the upper and downer computer. The article include Seven parts,they are the introduction,the main knowledge that system used, system requirement analyse, upper-computer soft design,downer- computer soft design,system debug,etc..At first the article introduced TPC sewage disposal craft, makes us know the realistic meaning of this craft and roughly technological process, but also the procedure directed against this craft provides the corresponding course monitoring and control system. The article introduces design processof systems soft ware especially, includes the upper-computer monitoring and control procedure,and the downer-computer control procedure, provide the overall design philosophy that the procedure writes, and also glozed some important programs. （科教范文网http://fw.NSEAC.com编辑发布）
