| Management information system and automation system based on computer and net has been used in each field of each vocation widely at present. These years, a body system of management and automation integrated by management information system and automation system was made great progress rapidly. How to realize transmission and alternation of data of system of automation and manage information opening, in high efficiency, shortcut without slot is still a significant problem. This paper analyzed the current technically actuality of data alternation of a body system of management and automation, and flat of research and development. With the real application of power plant SIS, it gave a whole designed scheme of power plant SIS based on technology of OPC, and the function realization of main module by visual basic –known tool by us. The paper described how to transmit real data into MIS through the opening, credible, high speediness alternation technology based on OPC. This spanned a great gulf fixed between real time system and MIS, decreased the degree of hard of integration, economized 25%-30% time of integrating system, and improved the efficiency greatly. |
