Abstract
In recent years along with the computer in the social domain's seepage, the PLC application was moving toward unceasingly thoroughly, simultaneously led the traditional control examination date crecent moon profit renewal. In the real-time examination and in automatic control's PLC application system, PLC often is takes a core part to use, only the PLC aspect knowledge is insufficient, but should also act according to the concrete hardware architecture, as well as in view of the concrete application object characteristic's software union, makes the consummation. This article introduced take S7-200PLC as the core, to some power supply bureau 110KV electrical network “two stations” the emergency power supply automatic investment installment (i.e. prepared turns oneself in) has carried on the control application, has summarized the S7-200PLC performance characteristic, elaborated emergency power supply automatic investment installment realization in detail Narrates the emergency power supply automatic investment installment software and the hardware design. First introduced this system's development significance and the use development environment, MPLAB the IDE system and the development use PIC monolithic integrated circuit chip as well as simulator PICMATE2002. Elaborated the hardware system design process in the hardware design, had determined the technical specification and component's choice, described each kind of chip function which and the characteristic emphatically the system hardware circuit design, the hardware design diagram and uses, analyzed the software design process with emphasis in the software design, the question which debugging part main introduction use debugging software picamate2002 and in the debugging process appears, as well as final solution question some methods.
key word: PLC two stand the emergency power supply to invest automatically
