摘要
提出了以OPC服务器为核心 ,ActiveX为OPC客户 ,通过Web网页对现场数据进行实时监控的系统设计与实现方案。该方案以COM/DCOM为基础 ,RPC为网络通讯协议 ,OPC为数据交换标准 ,WindowsDNA架构为手段 ,通过定义界限明确的三层结构来实现的。该实时监控系统实施方便、快速、成本低 。
Design and implementing strategy of the system for real time monitoring field data through Web page is stated. The system is composed of OPC server as the kernel and ActiveX as OPC client. The strategy is based on COM/DCOM, RPC communication protocol, and OPC data exchange standard. It edfined three layer structure of explicit boundary with measures of Windows DNA frame structure. The real time monitoring system features ease, fast speed, low cost and high feasibility.
