利用现有的公共电话网建立工矿企业的远程实时监控系统具有很强的实用性,针对McQuay公司水冷机组远程实时监控的应用环境,研究了基于公共电话网的信息控制系统的结构和实现方法,介绍了上位机监控软件和下位机可编程控制器的功能,给出了系统的设计方案及通讯功能的实现。
It's very practical to build the remote real-time industrial supervision system with the use of existing public telephone network.Such a system used to monitor the McQuay water-cooling machines is build.The structure of informa-tion control system based on public telephone network and its implement method are discussed.The functions of moni-toring software and program logical controller are described.The system design method and the implementation of com-munication module are also given in this paper.
