基于互联网的工业现场温度数据动态采集系统开发

目前，互联网技术的成熟促进了工业现场控制领域的深刻变革．针对多数工业现场冷热交加、工作条件苛刻的实际情况，提出了基于互联网的现场温度数据采集系统的解决方案．在给出数据采集系统通信原理的基础上，通过面向组件的Java编程语言(JSP／Servlets)和Visual C 6．0编程技术，实现了数据采集系统的信息通信．根据用户需求，实现了基于国际互联网的数据采集系统信息显示的动态刷新、浏览、查询和数据分析、备份以及数据采集控制等功能．该系统在大连理工大学计算机控制研究所S319．dlut．edu．cn服务器上试验，通过并联15个DUT3000模块对现场温度数据的21万条采集试验，验证了该系统的实效性和便捷性．

Development of dynamic acquisition system of industrial field temperature data on WWW

At present,the development of Internet has caused the deep technological changes in the industrial-control field.Aiming at improving the hash work conditions in the mass industrial fields of data acquisition, the authors put forward the solution that industrial field data is acquired based on World Wide Web mode. The communication principle of data acquisition system is given out.The implementation method for information communications of data acquisition system is elaborated by using programming technology of Java Server Pages (JSP),Java Beans components and Visual C++ 6.0.The control of data acquisition,data dynamical showing,data browsing and querying,data analysis and backup have been implemented by the developed acquisition system on WWW according to user's requirements which reduce the work intensity of the site operator efficiently.The system has been tested in Computer Control Institute of Dalian University of Technology with S319.dlut.edu.cn Server.210 thousand records of field data gathered by fifteen data modules of DUT3000 show that it is a very effective and convenient system.
