This dissertation is based on control vision system, which is one of the most important subsystems of MFIAS(Multiple-Fieldbus and Internet based Integrated Automation System).The system MFIAS has been appraised by the Chinese Academic of Sciences, and it has gained the national tenth five-year plan assistance. Control vision is the main theme of the industrial kingdom. In today's developing high-tech, control vision exists where manufacturing process exists. So most of the famous process control companies have their own control vision systems. For example, SIEMENS has Wincc, INTELLUTION has iFix, and WANDERWARE has Intouch. These companies have seized on large quotas in international and home markets. In our home country there are also many companies produces their own control vision systems such as configuration king and so on. Aiming at such instance, we have developed our own control vision system. Contrast to other systems, it has many virtues and innovational features as follows: 1. In the graphic design part, we solve the problem of filling any random three-dimensional shape only once. While in most other control vision systems, three-dimensional shape is piled up by simple graphic shapes, and the filling effect is not very ideal. We adopt the new color attemperment, and can fill any radom three-dimensional shape once. 2. Integrate VBA seamlessly. Only a few control vision systems integrate VBA overseas. In China, we can't find other systems doing this. 3. The system can link with many OPC servers. This is the only system can do this. 4. Integrate multimedia function. This is the first one to integrate it in our country. 5. Integrate advanced control function seamlessly. The main content of this dissertation is as follows: 1. The conception of Fieldbus is discussed. The history of Fieldbus development and its current actuality are also introduced. Then the background and characteristic of MFIAS are stressed. 2. The demand analysis and overall design of Control Vision System are introduced. 13. Detailed explanation for design and implement of the graphics part of control vision system. This part is the core and basic sect of control vision system. 4. Detailed explanation for design and implement of the integration of VBA. The merits and the step of integration are introduced. 5. The conception of OPC is introduced, and then some interfaces of OPC standard are discussed here. Finally, detailed explanation for design and implement of the integration of OPC are specified. 6. The summary of the dissertation is given, and besides, some beneficial advices are discussed for future work.
