The Research And Application Of Remote Supervisor System In Intranet

The development of the automation and computer technologies Especially withthe application of the internet/intranet makes possible the realization of remotesupervise. The emphases of CIMS are the integration of information network andcontrol network perfectly, and the construction of efficient remote supervise system,so it is a research hotspot too.This paper in the introduction and first chapter firstly summarizes thedevelopment, concept, network structure and common project, and proposed the ideathat builds opening remote supervisor system. And then the opening remotesupervisor system based on WEB in intranet are discussed, it include the three leveldeveloping mode based on Browse/Server architecture. In the last the brief modulesof remote supervisor system including data acquisition, data communication andserver design are analyzed.In the part of basic theory, we discuss all kinds of technology achieving remotesupervisory system, which include DDE, Winsock, COM/DCOM and Access todatabase. On the basis of the above-mentioned technology, a set of remote supervisorysystem was designed and accomplished. It used the mix model of C/S and B/S tosolve the problems encountered in the process of building a MIS for an industrialenterprise. The problems, of course, are follows: the data exchange between systemsof different structure and dynamic data declaration. According to this pattern, thereare several parts that include data acquisition in the substrate, data exchange inintranet, design of database server and web server. The whole process of the project isdescribed in the paper including critical code.
