地铁车站BAS的结构设计

Structural Design of BAS in a Metro Station

结合实际工程项目,对车站BAS结构设计中的控制器,网络及控制箱分布等问题作简要分析。认为控制器宜选择PLC的中高端产品,数量不宜过多;网络宜采用分层结构,利用工业级网络构建BAS控制层网络;系统的控制箱柜宜相对集中安装。

Considering an actual engineering project, the paper briefs the structural desiga questions for BAS on a metro station such as the controller, network, control cabinets distribution and so on. Medium and high quality PLC controllers should be chosen, but the number of the controllers may not be too many. The network should be of multi-level structure and those of the industrial levels should be chosen to construct BAS control network. The installation of the system＇s control cabinets should be relatively centralized.
