摘要
针对BAS中存在的系统集成难题,对控制网络和LonWorks技术作了深入解剖,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。文中以空调控制系统的软、硬件实现为例,分析了该系统通信的实时性,研究了基于LonWorks技术实施对各建筑设备系统及智能仪表的系统集成,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的现场总线技术在建筑智能化系统中有极好的应用前景。
Aimed at existent integrating puzzle of building automation system,the paper makes a deep analysis for control network needed by BAS strict requirement and LonWorks technology.Being combined with technology reconstruction of the specified major project,it builds a control network architecture of BAS based on LonWorks Field Bus in 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,and explored correlateive technical pazzle,specially the communication among subsystems.The engincering practice shows that it is a good application foreground based on LonWorks technology in the building intelligence system.
