The Rail Transit Building Automation System (BAS) is a high-performance and intelligent BAS control system that fully meets the characteristics of subway environmental control and urban climate differences, and integrates the latest technologies in the contemporary world. It can provide passengers and operators with a comfortable environment, and can effectively save energy and reduce operating costs.

The environment and equipment acquisition system controls the ventilation and air conditioning system, water supply and drainage system, lighting system, escalator system, guide system, screen door/safety door system through the on-site controller (PLC) equipment, and uploads the data to the BAS control workstation and station server monitor and process. At the same time, it is uploaded to the BAS control system of the line center through the backbone ring network line for synchronization monitoring.

The station BAS system adopts the main and standby dual-circuit network structure. The system access equipment (BAS workstations, station servers, etc.) such as BAS workstations and station servers are redundantly interconnected with the backbone network between stations through the main and standby dual switches.

The maintenance and backup centers use ring network switches for ring network redundancy connection, and the access devices of the two centers are connected to the two ring network switches of the corresponding center through the main and standby redundant connections.

The line center BAS system adopts the core switch main and standby redundant connection mode, and each access device (monitoring workstation, server, FAS workstation, etc.) is also connected to the core switch in the main standby connection mode.
