Computer Control System Of Object-oriented Modeling And Implementation

With the development of the modern industrial production, a computer control system is more and more important to the industrial process. Now a computer control system is designed and implemented mainly by Configure Software. Configure Software is a kind of professional software tool to design a computer control system with the supervision function and a friendly man-machine interface. As we know, there still are some shortages in the design of the structure and data of the computer control system. It is proved that the computer control system can be designed and implemented through the object- oriented method because of its some distinct characters. So in this thesis the computer control system is totally designed based on the object-oriented method for a kind of Configure Software which uses object-oriented method.There are three parts in this thesis. The first one is the object-oriented analysis. In this part, all kinds of functions and applications of this system are totally analyzed with the use case diagrams, and then the various entity classes, interface classes, control classes are analyzed, which are useful to the design and control of the computer control system. These classes'attributes and operations are abstracted and their relations are analyzed. The static model and dynamic model are built including class diagrams, sequence diagrams, collaboration diagrams, activity diagrams and statechart diagrams. The second part is object-oriented design, the system is constituted and the man-machine interface, the task management and database management are designed. The concrete design method of the system is given. In the third part, a man-machine interface is developed by Visual C++6.0 to validate the feasibility and rationality of the above model. Some basic functions are implemented and a kind of simple PID control system has been realized, which is applied to a practical hydraulic level control system.The object-oriented model of the general computer control system is first pointed out by the author in this thesis, so it is an original work. The object-oriented Configure Software can be developed based on this model. Other special computer control system object-oriented models also can reference this model.
