1. A brake control system comprising:

  • a train level brake control unit (TBM) for connecting to a brake command source via hard wire to receive a brake command;

    one or more network segments, wherein each network segment comprises;

    a segment-level brake control unit (SBM) for receiving a brake command from the TBM through the network;

    one or more Local Brake Control Units (LBCUs) for receiving braking commands from the SBM over the network,wherein the one or more LBCUs are further configured to receive a braking command from a braking command source via a hard wire,and the one or more LBCUs receive the braking instruction sent by the SBM of the network segment where the one or more LBCUs are located preferentially when the braking control system is in a normal working condition, the one or more LBCUs receive the braking instruction from the hard wire only when the one or more LBCUs have network faults and cannot receive the braking instruction from the SBM, and other LBCUs without the network faults receive the braking instruction from the SBM of the network segment where the other LBCUs are located.
