通信协议与IT技术在智能建筑系统集成中应用研究

Research on Application of Communication Protocols and IT Technologies in System Integration of Intelligent Building

在楼宇自控系统BACS中实现集成和互操作的最好方法是在各层执行统一的通信标准,BACnet是可选之一。OPC和Web Services技术在实现管理层的集成和互操作性方面各有优势,分别给出了集成方法和集成结构。最后提出最佳的解决方案将是它们两者的结合。

The best way towards integration and interoperability of Building Automation and Control System(BACS) is to implement a unified communication standard for all levels of BACS. BACnet is one of candidates nowadays. In practice, various communication protocols may exist for a long time due to market reasons. Therefore, the integration at management level is very necessary. Both OPC and Web services are good candidates for achieving integration and interoperation at the management level, the integration methodology and the integrating framework are presented respectively .Pros and cons of OPC and Web services are analyzed and compared. But the combination of these two technologies will be the best solution.
