The invention discloses a control method and system for a main compressor of a power centralized motor train unit. The pressure value of the first main air cylinder of the power vehicle is used as a main compressor start-stop judgment basis, the pressure values of the second main air cylinder of the motor vehicle and the second main air cylinder of the control vehicle are used as the start-stop judgment basis of the main compressor so that the situation that the second main air cylinder of the control vehicle is far away from the air source to cause insufficient total air pressure to easily trigger the vehicle set to block traction is avoided; meanwhile, when the pressure values of the first main air cylinder and the second main air cylinder of the vehicle are both higher than a second preset value and the pressure values of the second main air cylinders of other vehicles are higher than a third preset value, the main compressor of the vehicle is controlled to stop, and the problem that vehicle air equipment is damaged due to the fact that the pressure values of the first main air cylinder and the second main air cylinder of the power vehicle are too high is solved.

    本发明公开了一种动力集中动车组主压缩机控制方法及系统,不仅采用动力车第一总风缸的压力值作为主压缩机启停判断依据,还采用动力车第二总风缸和控制车第二总风缸的压力值作为主压缩机启停判断依据,避免了由于控制车第二总风缸远离风源导致总风压力不足而易触发车组牵引封锁的情况;同时,当本车第一总风缸和第二总风缸的压力值均高于第二预设值,且其他车第二总风缸的压力值高于第三预设值时,控制该本车的主压缩机停止,避免了动力车第一总风缸和第二总风缸压力值过高导致车辆用风设备损坏的问题。
