Plc Training System Software Platform, Development And Design

This paper depends on the university's laboratory items of basic construction "synthesis training platform of industrial control system". Author has designed its constituent "the PLC training system" software platform. It gives the automation and the related specialized undergraduate by the convenient design environment and the clear concept and exercises then industrial control system design ability.This paper analyzs the current PLC experiment teaching present situation first, proposed a new laboratory construction plan called "the software simulation object + hardware controller". Then this paper has carried on the whole introduction to this project design's PLC training system overall. Then it has introduced the software platform each constituent with emphasis,include the program in the MCU, the design of simulation of controlled plant on PC,the manage platform and related databaseon PC machine. To discuss the Communication part, this paper has formulated a custom communication protocol and has designed two dlls based on the protocol. One uses for the USB communication and the other uses for the Ethernet communication. This paper has analyzed the simulation controlled plant principle and technical and its product software SIMIT. In addition it has discussed the OPC technology with emphasis and has designed the OPC data accessing client software and the server software in VC project.This paper introduces finally take two simulation controlled plant as the example of using software platform of the "PLC training system", and confirmes its effection in PLC experiment teaching through them. It can be see the great value of this system in the Practical application because it makes the college student majored in automation and some correlation can get the training which like a real control system.
