Abstract: Realizing the information integration from bottom process control level to application level has important significance in the process of enterprise integration automation. By studying the OPC XML-related technologies, an information integration method based on OPC-XML is proposed, the system architecture of the B/S mode is designed, and an independent OPC XML-DA server and its corresponding client are developed. When it is applied in petrochemical enterprises, the system implements the function of real-time access and remote detection to bottom layer data. It provides foundation for higher level system integration of the enterprise, and promotes the realization of enterprise integration automation.

摘要： 实现企业过程控制底层和应用层的信息集成，在企业实施综合自动化过程中具有重要意义。在研究OPC-XML的相关技术的基础上，提出一种基于OPC-XML的信息集成方法，构建B/S结构的系统构架，并开发独立的OPC XML-DA服务器与客户端。该系统应用在某石化企业中，较好地实现对底层数据的实时访问和远程监测，为企业更高层次的系统集成提供了基础，促进企业综合自动化的实现。
