摘要
针对BAS中存在的系统集成难题,结合某工程的技术改造,构建了基于LonWorks总线的BAS控制网络结构。文中分析了集成系统通信的实时性,探讨了相关技术难点,特别是各子系统之间的通信问题。工程实践表明基于LonWorks的现场总线技术在楼宇自动化系统中有极好的应用前景。
Aimed at existent integrating puzzle of building automation system, combined with technology reconstruction of the specified major project, it builds a control network architecture of BAS based on LonWorks Field Bus in the paper. The paper took software and hardware realization for air conditioner control system as an example, and analyzed the real-time property of the system communication. The paper also studied the system integration of implemented building device systems and intelligent instruments based on LonWorks technology, specially the communication among subsystems. The engineering practice shows that it is a good application foreground based on LonWorks technology in the building intelligence system.
