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.
