摘　　要：环控系统在轨道交通中起着重要的作用,它的构建直接影响地铁应用效能的水平。以沈阳地铁BAS系统为背景,介绍了BAS系统的网络架构,通过对骨干网实时性与安全性进行对比分析,选取性价比优越的星型结构应用在地铁中,并提出了车站级IP地址的分配建议,以提高BAS系统实施的效率,同时降低风险,对地铁的安全运营提供保障。这种网络架构的设计对同类地铁车站的设计具有很高借签意义。BAS system plays an important role in subway that directly affects the application efficiency of subway.Based on Shenyang subway BAS system, this paper introduces the BAS system network architecture.The star structure with higher cost performance is selected to apply in the subwayand the allocation of the subway station IP addressis proposed through comparing the real-time performance with securityof the backbone network. The reasonable IP address allocation can improve the efficiency of BAS system implementation and reduce risk. Meanwhile, the IP address allocation can be used for a reference to the design of similar subway station.
