【摘要】：目前随着网络技术和信息化技术的快速发展,运用互联网技术开发出的基于Web的远程监测系统已经在工业生产等领域得到了广泛的运用。本文研究对象是基于工业污水处理过程的远程水质在线监测系统,由于传统的监测系统大多采用集中式结构和C/S(Client/Server)架构,系统软件之间的耦合度较高难于扩展,并且软件依赖于硬件平台,不能实现资源重用与满足远程监测的需求。所以考虑采用B/S(Browser/Server)架构来搭建整个系统,实现对分布式污水处理站点的远程实时监测。本文首先对课题研究的背景和意义进行了介绍。纵观目前国内外对此课题发展现状的研究,进而分析了系统在开发过程中所面临的难点,并详细讨论了系统中几个重要的技术问题,其中包括系统底层数据通信协议的研究、数据库信息管理系统的设计与开发和系统的实时性和可靠性分析;针对Web服务器端,课题主要分析讨论了数据库的访问技术、数据的实时传输以及实时数据在页面的动态绘制等重要问题。最终制定出技术实施路线,开发出基于Web的水质在线远程监测系统。系统整体采用B/S模式开发,在系统底层数据通讯方面,制定了两种数据通信接口,一种是基于OPC(OLE Process Control)技术编写了 OPC客户端程序;另一个是采用Socket实时通信技术实现了现场底层设备数据的采集。Web服务器端采用ASP.NET技术开发,选用Microsoft Azure云存储方案来实现场数据的实时存储,远程用户可以随时通过浏览器监测污水处理现场的实时数据,进行历史数据查阅与报表统计,同时系统还具备故障报警及视频监控等功能。目前系统已运用于实际项目中,运行状态良好,验证了系统的可行性与实用性。
[Abstract]:With the rapid development of network technology and information technology, the remote monitoring system based on Web developed by Internet technology has been widely used in industrial production and other fields.The research object of this paper is the remote water quality on-line monitoring system based on the industrial sewage treatment process. Because the traditional monitoring system mostly adopts the centralized structure and the C / S client / Server architecture, it is difficult to extend the coupling degree between the system software.And the software depends on the hardware platform, so it can not realize the resource reuse and meet the requirement of remote monitoring.So consider using B / S browser / Server architecture to build the whole system to realize the remote real-time monitoring of distributed sewage treatment stations.This paper first introduces the background and significance of the research.This paper makes a survey of the current research on this subject at home and abroad, and then analyzes the difficulties that the system faces in the development process, and discusses in detail several important technical problems in the system, including the research of the data communication protocol at the bottom of the system.The design and development of database information management system and the real-time and reliability analysis of the system.Real-time data transmission and the dynamic rendering of real-time data in the page and other important issues.Finally, the technical implementation route is worked out, and the water quality online remote monitoring system based on Web is developed.The whole system adopts the B / S mode to develop, in the system bottom layer data communication aspect, has established two kinds of data communication interfaces, one is based on the OPC(OLE Process control technology has written the OPC client program;The other is to use Socket real-time communication technology to realize the data acquisition of the field bottom equipment. The web server is developed by ASP.NET technology, and the Microsoft Azure cloud storage scheme is used to realize the real-time storage of field data.Remote users can monitor the real-time data of sewage treatment site through browser at any time, and carry out historical data inspection and report form statistics. At the same time, the system also has the functions of fault alarm and video monitoring.At present, the system has been used in the actual project, the running condition is good, which verifies the feasibility and practicability of the system.
