The BAS is a system model that adopts computer network technology, automatic control technology and distributed intelligent communication technology to achieve decentralized control and centralized management of equipment monitoring.

It provides comprehensive and effective automated monitoring and management of equipment, including station and tunnel ventilation and air conditioning systems, water supply and drainage systems, escalator and elevator systems, low-voltage power distribution, and lighting systems. The system collects and processes relevant data, archives historical records for maintenance management, and ensures equipment operates in a safe, reliable, efficient, and energy-saving optimal state. While maintaining a universally safe station environment, it achieves energy efficiency optimization.

In emergencies such as train blockages or fire incidents, the system efficiently coordinates station equipment to operate in disaster recovery mode, fully leveraging the emergency functions of various devices to ensure passenger safety and the normal operation of equipment.
