  • LOCOMOTIVE BRAKING CONTROL SYSTEM AND CONTROL METHOD
    Publication number: 20220105917
    Abstract: The present application belongs to the field of locomotive braking control, and relates to a locomotive braking control system and control method, including a brake cylinder equalizing pipe control system and a brake cylinder control system; wherein, the brake cylinder equalizing pipe control system can compare pre-control pressure of the brake cylinder and the pre-control pressure of the brake cylinder equalizing pipe, and output the higher one as the brake cylinder equalizing pipe pressure; and the brake cylinder control system can compare pre-control pressure of the brake cylinder and the brake cylinder equalizing pipe pressure, and output the higher one as the brake cylinder pressure to realize brake; the redundancy of the two control systems can also be realized.
    Type: Application
