The invention discloses a locomotive and an air backup braking system and method thereof. The system comprises a backup balancing air cylinder, a backup braking valve connected to the backup balancing air cylinder and a backup relay valve connected to the backup balancing air cylinder and a main air pipe. The emergency braking protection system further comprises an emergency braking protection unit which comprises a control air cylinder used for storing compressed air with the pressure equal to that of the train pipe, and the emergency braking protection unit is used for cutting off a passage between the backup balancing air cylinder and the backup braking valve according to the pressure of the control air cylinder and the pressure of the train pipe. A passage between the backup balancing air cylinder and the atmosphere is conducted, the pressure of the backup balancing air cylinder is discharged to zero, and meanwhile, a passage between the backup relay valve and the main blast pipe is cut off; or; and a channel between the backup balancing air cylinder and the backup brake valve is conducted, a channel between the backup balancing air cylinder and the atmosphere is cut off, and meanwhile a channel between the backup relay valve and the main blast pipe is conducted.

    本发明公开了一种机车及其空气后备制动系统与方法,上述系统包括:后备均衡风缸、连接于后备均衡风缸的后备制动阀以及连接于后备均衡风缸与总风管的后备中继阀;还包括:紧急制动保护单元,紧急制动保护单元包括用于存储与列车管的压力相等的压缩空气的控制风缸,紧急制动保护单元用于根据控制风缸与列车管的压力,切断后备均衡风缸与后备制动阀之间的通路,并导通后备均衡风缸与大气的通路,将后备均衡风缸的压力排零,同时切断后备中继阀与总风管之间的通路;或;导通后备均衡风缸与后备制动阀之间的通路,并切断后备均衡风缸与大气的通路,同时导通后备中继阀与总风管之间的通路。
