建筑自动化系统拓扑结构及其发展趋势分析
Analysis of topological structure and developing trends of building automation systems
摘要：
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。
Abstract：
There are more than ten famous brands of foreign building automation (BA) systems in China’s market. The topological structure of BA systems can be classified into four categories—connecting the site layer and the management layer with gateways or network controllers, connecting the management layer with direct digital controllers via TCP/IP and the complex formed by every two categories of the above. Analyses their topological structure based on some specific brands. Presents the three major developing trends of BA systems, i.e., the achievement in industrial control domain being applied to refinement of traditional BA control strategy, the achievement in communication domain to BA system domain and the achievement in IT domain to BA system domain. Considers that the tendency of mechanotronics of air conditioning subsystem may damage BA’s overall situation and integrity.
