The Research On Fieldbus Technology And Network Monitoring Configuration System

This article analyzes the composition and development of modern factory controlling system and enterprise information system, the character of fieldbus control system, and discusses the technical specialties of fieldbus, communication protocol and message communication mode in a big way. This article also makes an analysis of the design and key technology of YSS2000 system, investigates the design and realization method of configuration software and database application software, and discusses the design, structure and realization of Device configuration sub-system and Device Data Export / Import sub-system, combined with the actual development and research project. In the realization of key sections, depends on the upstanding support of Borland C++ Builder BDE to database, the reasonable design of database, data structure, and the organization of memory, the stabilization and efficiency of system are improved greatly, some limitations of BDE are avoided meanwhile. With the ues of stream file, the size of database export file is reduced remarkably, and the package of relating file is exported or imported at the same time. All of these avoids the problems occurred when use SQL Server simply, fulfils the requirement of user well. At the end of this article, a prospect is made.
