In recent years , with the rapid development of high-tech , people living and working environment , increasing demand , Intelligent Building System Integration in the intelligent building engineering is also increasing. According to statistics, the country 's stadiums, convention centers, airports, hospitals and other large buildings , intelligent construction, are for the weak subsystem integration in order to achieve a unified information management . \Based on the building management system functionality to be achieved from the network integration, functional integration , and software interface integrated three -level design building management systems . Research in Intelligent Building System Integration OPC technology , ODBC technology , WINSOCK technical principles , implementation and application of the model . And Intelligent Building System Integration for data communications capacity, data structures and diverse, the system real-time requirements , etc., studies to optimize building management system software. Via the OPC interface to \Through the system database reasonable vertical and horizontal division , combined with data on different types of data to be flexible storage, database storage structure optimized to improve the program on the system database called speed. Rich functionality using VB controls , modular design, improved efficiency of program development , and through WINSOCK control to achieve real-time monitoring elevator equipment , provided by the manufacturers of video controls for video monitoring. In this paper, user needs , using the background , the system database , front three-tier architecture model development of Guangzhou University of Foreign Studies campus level building management system . System operation interface is beautiful, vivid , intuitive , and has extensive management capabilities , the system response speed of the targets are met user requirements . During the test run the system is stable , the user has the praise . This paper summarizes the papers last major work done , noting that some of the platform areas for improvement and to further improve the way .
