摘　　要：总结和借鉴了国内外网络实验室的发展现状和经验,将一套本地实验装置扩展为基于Web的远程实验平台。重新设计了原实验装置的控制单元,以现场总线、工业以太网为通信枢纽,OPC为软硬件通信接口与网际组态软件Webaccess的监控节点相连。校园网或Internet用户可通过Webaccess,实现锅炉液位的远程控制和控制单元PID参数的远程调整,为构建远程实验平台提供了一种实用的解决方案。By summarizing and referencing the current status and experience of the domestic and overseas network laboratories, a local boiler experimental device is extended to Web-based remote experimental platform. The control unit of the original experimental device is redesigned with the field bus and industrial Ethernet as its communication hub, and OPC as its hardware/software communication interface connecting to supervisory node of Webaccess. Remote control of boiler level and remote tuning of PID parameters via campus net or Internet are achieved. A practical solution to building Web-based remote experimental platform is presented.
