摘要
基于Internet的多监控点远程监控系统大多是单监控点系统的推广,这些多监控点系统只能对各测控点进行分时监控,不能对整个系统进行统一的调控,而且各测控点都需要固定的IP地址。为此,本文提出了一种基于数据库的Internet分布式多监控点远程监控系统解决方案。系统可对多监控点状态进行实时的监测,数据汇总、统计和分析和集中调控,各测控点不需要固定的IP地址;系统采用两级数据库实现了数据的缓存,有效解决了Internet网络数据传输不稳定的问题;系统设有Web服务器,通过WWW浏览器可对系统运行状况进行监控。本文给出了系统整体结构和系统各组成部分硬件、软件详细设计与具体实现。在校园网和城域网环境下对系统进行了实验测试。实验结果表明:系统可应用于中低速自动化监控领域,随着Internet网络数据传输速率的提高,系统监控的实时性将进一步得到提高。
In this paper, a remote distributed Multi-node supervisory control and data acquisition system is introduced based on the Internet and database technology. The design and implementation of the hardware and the software of the system is discussed in detail. The test results of the system on the Internet are also presented. The system consists of three components： local controller, supervisory control center （including database server, Web server and supervisory control workstation） and supervisory terminal. The structure of two level databases is used in the system which provides a data buffer for unstable data communication via internet and avoids data drop. A Web server is constructed by Java Script Page （JSP） technology in the system, through which engineers can remotely supervise the work state of the hole system by an internet connected PC via WWW browser. The system has the advantages of multi-node control, more flexibility, more convenience, and lower communication cost. It has been used in the field of the city heater supply supervisory control. It also has a great application foreground in the supervisory control field of industry manufacture, water conservancy, electric power and environment.
