| The graph configuration system is an important part of the development environment in configuration software. The system abstracts concrete objects in the control field using graphics mode, builds the relationship of them, and forms technique flow chart and mutual view between user and system in the end.This thesis in refers to the domestic and foreign mature configuration software's foundation, chooses the design method of the module modulation to carry on the design to software's main body construction. The overall system works under the Windows2000 system, taking Visual C++ as the platform. It is divided into three modules: the primitive storehouse, the animation connection storehouse and the Web page real-time data issued system. We have carried on the structure analysis, the model analysis separately to it, then make the programming realized. The system uses the object-oriented method to carry on the development design. We have given various main body class structures, attribute and the method of the modules, and make the brief narration on how to realize the methods' functions. In the Web page real-time data issue module, we discussed two ways to issue the real-time data on Internet: through the XML technology which unifies with IE, and through ActiveX technology. The user long-distance browsing field data environment functions have been completed. We selected ActiveX in the actual system development to control to download to the customer computer, through the server issued that the real-time scene flow data realized the Web function.The system will work together with the other modules to build a simple configuration software industrial automation control system. In the last article, we use SQL Server2000 simulated real-time database, test the system through the simulation of oil control system. The system achieved the expected results, by showing charts of real-time data from the database, and gave the process of vivid image user-friendly, stably. |
