For Plc Configuration Software System Research And Implementation

Along with the fact that social progress and the acceleration of information speed, Configuration Software has been applied more and more frequently in every walk of life. Configuration Software is simple and easy to use. Its strong function and outstanding stability make it used not only in industrial environment, but also in daily life, for example: supervisory and control of dam water level, temperature controlling in industry scene, automation motor stoppage equipment, elevator promotion and demotion controlling, and production line controlling, etc. It can also be used in intelligent building management, office acousto-optic control, and temperature adjust, etc. By this token, Configuration Software will be able to win gigantic marketplace space. Taking these as background, the research being engaged in Configuration Software aspect has important research significance and practical value.Firstly, the conception and background of the Configuration Software are introduced, the domestic and foreign situation of development and the change of function are analyzed, and several kinds of popular Configuration Software nowadays at home and abroad are introduced simply. Then, the whole structure, the idea of design and the interrelated technology are introduced. At the same time, the Graphical Interface, the Data Communication, and the Real-Time Database supporting are analyzed, researched in detail. And the concrete realization methods of the Graphical Interface, the design of the Data Communication and the Real-Time Database supporting have been provided. Finally, the development trend of Configuration Software technology is discussed in open, supporting Internet, applying in embedded system and expanding application area, etc.The technique of Object Oriented Programming is applied in the whole system. It takes good advantage of OOP's properties of encapsulation, inheritance and polymorphism. And the independence, robustness and expansibility of Configuration Software are realized. The Graphical Interface is implemented by Visual C++6.0, it uses multiple documents-view structure on structure, stores data in document class, demonstrates graphics in view class. And also divides the design into two parts, graphics edit and motivation connection. After the design of the Graphical Interface, the scene acquisition data need to be received to form the dynamic graphics and to reflect various industry scene state, and also to control the equipments in the scene. These all are dependent on Configuration Software's communication module, the system chooses the method of Serial Communication for its communication module.
