基于web的远程监控系统 摘 要 随着自动控制技术和网络通信技术的巨大发展，为了满足现代企业对生产过程自动化和信息管理的新要求，基于web的远程实时监控已成为解决企业地域限制、提高工艺控制水平和企业管理水平的普遍需求。 本文通过分析基于web的远程监控系统在国内外发展和研究现状，全面介绍了基于web的工艺参数远程监控系统的总体结构和应用技术，结合某化工厂酚醛树脂储液罐温度控制系统，提出了储液罐温度远程监控系统的技术方案，并完成了该系统的设计。 本文主要工作如下： 给出了采用TCP/IP技术，B/S体系结构的基于web的储液罐温度远程监控系统设计方案，分析在Internet/Intranet环境下实现实时数据发布和远程控制的可行性。 利用杰控组态软件Fameview制作储液罐温度远程监控系统上位机监控画面，以研华PCL-812PG作为I/O接口设备完成下位机数据交换，结合组态软件的web发布功能将现场工艺参数与Internet连接起来，实现对工艺参数的远程监控。 本文综合了现场监控和远程监控，设计并实现了储液罐温度远程监控系统，给出了一种低成本的工艺参数远程监控系统设计方案，具有良好的经济效益和应用推广价值。 关键字: web; 远程监控；储液罐；组态软件；Fameview; Abstract With the tremendous development of automatic control and communication technology of the network, in order to meet the new requirements of modern business process automation and information management, remote web-based real-time monitoring has become to solve business general needs of the geographical restrictions business and improve the process control level and the level of business management . This paper analyzes the development and research of the web-based remote monitoring system at home and abroad, and give a comprehensive introduction of the overall structure and applied technology to web-based remote monitoring system for industrial parameters. With a chemical plant control system of tank temperature of phenolic resin, proposed the technology program of tank temperature remote monitoring system , and completed the design of the system. In this paper, as follows: Proposed the design program of web-based remote monitoring system of tank temperature ,by using TCP / IP technology and B / S architecture. Analysis to achieve real-time data distribution and remote control is feasible in the Internet / Intranet environment . Make the host computer monitor screen of remote monitoring system of tank temperature, using configuration software of Fameview products. Use Advantech PCL-812PG as I / O interface device to complete the next-bit machine data exchange, link the technical parameters of industrial site to Internet
