摘要
在分析分布式实时监测系统结构及实时数据处理的基础上 ,提出一种通用实时监测应用服务器设计方案。本应用服务器采用多线程机制 ,在线采集工业控制的实时数据 ,通过浏览器可视化组件动态发布设备运转及生产状况信息。本方案具有完善的页面请求、客户请求、以及数据对象的管理和服务功能 ,其结构灵活 ,系统维护性强。
Based on the analysis of the architecture of a distributed monitoring system and its real time data processing,this paper presents the design of a general real time monitoring application server,which is implemented by multi thread.It gathers the real time data of the control system in an on line way and sends the data to a remote browser,on which the visual components display the real time data dynamically.The application server has the good functions of management and service for data objects along with the requirements of web pages and users.The system structure is flexible.
