The invention relates to a heavy-load train locomotive brake pressure reduction control system and method. The heavy-load train locomotive brake pressure reduction control system comprises a brake mechanism, a brake control unit, a protection electromagnetic valve and a brake protection device. The brake mechanism comprises a train pipe, a relay valve and a balance air cylinder. The protection electromagnetic valve is arranged at the air outlet of the balancing air cylinder; the brake protection device is in communication connection with the brake control unit and monitors whether the brake control unit breaks down or not in real time, when the brake control unit breaks down, the connecting pipe controls the protection electromagnetic valve, the exhaust air rate of the balance air cylinder is calculated, and the exhaust action of the balance air cylinder is controlled based on the exhaust air rate. The brake protection device is arranged in the brake system, so that the pressure of a train pipe is prevented from being reduced to zero under the condition that a brake control unit of the train breaks down, stable braking of the heavy-load train is guaranteed, and the running safety of the train is remarkably improved.
本发明涉及一种重载列车机车制动机减压控制系统及方法,包括:制动机构、制动机控制单元、保护电磁阀和制动保护装置;制动机构包括列车管、中继阀和均衡风缸;保护电磁阀设置于均衡风缸排风口处;制动保护装置与制动机控制单元通信连接,实时监听制动机控制单元是否发生故障,当发生故障时,接管控制保护电磁阀,并计算均衡风缸的排风量,基于该排风量控制均衡风缸的排气动作。本发明通过在制动系统中设置制动保护装置,避免了列车在制动机控制单元故障情况下列车管减压至0,保障了重载列车平稳制动,显著提高列车运行安全性。
