The Analysis And Construction Of Simulation System For Controlled Objects

Controlled objects exist widely in the industry and science research. Their properties and their control systems are the keys to keep them operating accurately and safely. But acquiring the properties and debugging the application program always need experiments in the industry plants. It will cost much. Therefore, an effective scheme is urgently demanded. The solution is to represent control objects on computers and some peripheral equipment with simulation technology. It can simulate controlled objects and debug application program in the laboratory. This scheme will supply the feasibility and instruction for designing, operating and controlling the objects. This paper first introduces the simulation technology in detail, then gives the methods and procedures of the simulation system. According to the properties of the controlled objects in the industry and research, design a two-level structure as a whole. The plant microcomputer adopts interface circuit board of STD Bus, which acquiring data and outputting control signals. The software of manage computer is completed mainly using object-oriented method, with Visual Basic program language and Access database. At last, using this scheme to simulate the temperature of medical glucose crystal process system, at the same time, using the application program control the simulation system. The results of the experiments are effective. In a word, this paper offers a method to develop the simulation system about controlled objects in the industry and research.
