基于OPC UA的自动化系统集成技术研究

摘要

针对在实现自动化领域的系统集成过程中,子系统或者设备之间的互操作与信息共享的难点问题,提出以OPC UA(OPC unified architecture)为标准接口构建系统集成的抽象框架,并开发了OPC UA 客户端和服务器,利用组态王完成了集成监控软件的开发,解决了某国防工程管理自动化系统集成中的"信息孤岛问题".实践证明,基于OPC UA的系统集成具有平台无关性,能够跨越防火墙传输数据,可有效解决系统集成中的异构问题.%Aiming at the difficulty of interoperation in subsystems or devices in the implementation of system integration implementation in automation domain, an abstract frame constructed based on OPC UA( OPC unified architecture) is put forward as standard interface. OPC UA client and server are developed. KingView is used to complete the development of integrated supervisor and control software, and the problem called information solitary island in the process of one national defense project' s automation system integration is resolved. Testified by the practice, the system integration based on OPC UA provided with platform independence, can transport the data across firewalls, and can settle the problem of the heterogeneous in system integration.
