The invention discloses an emergency shutdown control method, device, equipment and medium of a hydrogen fuel hybrid power locomotive, and belongs to the field of hydrogen fuel hybrid power locomotives, the method is applied to a TCMS of the hydrogen fuel hybrid power locomotive, and a main circuit breaker is connected with a control switch of a hydrogen fuel system output loop in series; the method comprises the steps that when an emergency shutdown instruction is received, a main circuit breaker is turned off, and the emergency shutdown instruction is sent to the hydrogen fuel system through the main circuit breaker in a hard wire connection mode and a bus at the same time, so that an air inlet valve of the hydrogen fuel system is turned off; turning off the DC/DC converter, and consuming energy generated by the hydrogen fuel system within the emergency shutdown delay time by using an auxiliary machine device of the hydrogen fuel system; and when the energy consumption is finished, if the hydrogen fuel system is successfully shut down, judging that the hydrogen fuel hybrid power locomotive is successfully shut down emergently. By means of the method, the safety and reliability of the hydrogen fuel hybrid power locomotive during emergency shutdown can be further improved.

    本申请公开了一种氢燃料混合动力机车的紧急停机控制方法、装置、设备及介质,属于氢燃料混合动力机车领域,该方法应用于氢燃料混合动力机车的TCMS,其中,主断路器与氢燃料系统输出回路的控制开关串联;该方法包括:当接收到紧急停机指令时,关断主断路器,并利用主断路器通过硬线连接的方式以及通过总线同时向氢燃料系统发送紧急停机指令,以关断氢燃料系统的进气阀门;关断DC/DC变流器,并利用氢燃料系统的辅机装置消耗氢燃料系统在紧急停机延迟时间内所产生的能量;当能量消耗完毕时,若氢燃料系统成功停机,则判定氢燃料混合动力机车紧急停机成功。通过该方法可以进一步提高氢燃料混合动力机车在紧急停机时的安全性与可靠性。
