基于B/S模式的Rockwell实验室网络监控系统

应用OPC通信技术和Web开发技术,设计并开发了基于B/S模式的Rockwell实验室网络监控系统。OPC的应用多是基于C/S模式的,这导致在传统B/S模式网络监控系统下,数据通信过程要通过OPC服务器、OPC客户端和实时/历史数据库多层通信,存在一定的实时性问题。针对这一问题,提出了新的开发框架,实现了与控制对象的实时通信。用户通过浏览器可以实时监视设备的运行状况,并且可脱离Rockwell的编程软件对设备进行控制。

Network Monitoring System of Rockwell Laboratory Based on B/S Mode

A network monitoring system of Rockwell laboratory based on B/S mode is developed,using OPC communication technology and Web developing technology.As OPC applications are mostly based on C/S mode,data communication of the traditional network monitoring system based on B/S mode is a multi-layer communication process,which includes OPC server,OPC client and real-time/history database.As a consequence of the traditional system,there are some problemsfor real-time communication.To solve this problem,the system presentes a new development framework to achieve real-time communication with the control objects.The user can monitor the running status of the devices in real time through the browser,and control the devices without using the programming software of Rockwell.
