摘要
采用OPC方式实现了对组态软件RSView32中变量数据的读取,由COM服务器暂存读取到的最新数据,信息管理系统定时从COM服务器获取数据,通过AJAX异步刷新技术,把得到的数据以趋势图或监控画面的形式显示在IE浏览器中,解决了管理系统读取和显示组态软件实时数据的问题。
In this paper,the mothed of OPC is used to access the variable data of configuration software RS-View32,Then These latest data is temporarily stored in the COM server.By means of AJAX (asynchronous ref-resh technology),the data which Information Manage-merit System has gained from COM server in fixed time is demonstrated by tendency char or monitoring picture form.The problem that real-time data of configuration software is readed and displayed by Information Management System has been solved.
