Based On The Overall Framework Of The Vc + + Computer Configuration Software Design And Implementation

The design of configuration software for industrial control is a huge and complex engineer , It抯 also an arduous challenge . With the author抯 practical experience in the design of configuration software for industrial control for two years, the paper mainly discusses how to design the whole frame and the realization means of medium and small configuration software of industrial control, and also provides part source code based on VC++6.O The whole system can be divided into several subsystem flow chart subsystem real-time database subsystem~ running subsystem~ communication subsystem. The paper mainly discusses the design of flow chart subsystem and real- time database subsystem0 and also summarily discusses the application of OPC in the process control. The design of the configuration software refers to several domestic and overseas products, such as Intouch (USA 憇 wonderware company 1. Wince (SIMENC company).. KingView(Beijing YaKong Company)and so on, on such a base We increase our own characteristic: Firstly, Using ActiveX technology to improve the software抯 Extensibility; Secondly, using VC++ and YB language to program mixedly, making good use of yB抯 strong and high-efficient ability to create graphics interface , using Access Database, Using VC++抯 good function to manipulate the EMS memory and hardware. YB and VC++ are both Microsoft抯 products, so they are easy to be connected with each other, this programming means can efficiently reduce the developing period; Thirdly , Using OPC (OLE for process control) to solve the communication problem between configuration software and below-machine, OPC defines uniform interface standard , it realizes that a communication device can be easily added to the system to run at once, don 憈 need device driver; Fourthly, real-time database system exists in DLL, the ActiveX Movie component (using other language to program such as YB and C++Builder) can access reat-time database system. The realization of the whole frame set up a good basic for next year抯 postgraduate to continue this project抯 research and development.
