目前活跃在国内市场上的国际著名的建筑自动化(BA)系统品牌不下十余种,其BA系统拓扑结构可分为四类:以网关连接现场层和管理层、以网络控制器连接现场层和管理层、DDC直接经TCP/IP连接管理层以及前三类的两两混合。结合具体的品牌对四类BA系统的拓扑结构进行了剖析。介绍了BA系统的三个主要发展趋势:工业控制领域的成果将越来越多地应用到BA系统的传统控制策略的改进,通讯领域成果开始应用到BA系统领域,IT领域成果正在向BA系统领域渗透。认为目前出现的空调子系统机电一体化的倾向可能会破坏BA系统的全局性和整体性。
At present, there are no less than ten brands of internationally renowned building automation (BA) systems active in the domestic market. The BA system topology can be divided into four categories: the gateway connects the field level with the management level, the network controller connects the field level with the network level controller, Management, DDC directly through the TCP / IP connection management and the first three types of mixed. With the specific brand of four types of BA system topology were analyzed. Three main trends of BA system are introduced: the achievements in industrial control field will be more and more applied to the improvement of traditional control strategy of BA system, the achievements in communication field will be applied to the field of BA system, and the achievements in IT field are being applied to BA system Field penetration. It is considered that the tendency of the current mechanical and electrical integration of the air conditioning subsystem may undermine the overall and integrity of the BA system.
