In response to the safety hazards caused by improper manual opening of doors and improper touching of electrical buttons by passengers during the operation of track operation car,this paper designed a car door control and video surveillance system for track operation car based on ARM Cortex-A-8 embedded platform,elaborated on the hardware design scheme,software architecture,core business processes,as well as functions such as door control,video capture,and video display of the system.Through key technologies such as electrical level conversion,multi-channel device status monitoring based on select/roll functions,and visual monitoring,the paper implemented automatic locking and opening of the doors of the track operation car,as well as real-time monitoring of passenger behavior.The trial results show that the system runs stably,can ensure the safety of track operation car,and has certain usability.
