The invention discloses a shutdown control method, device and equipment of a hydrogen fuel hybrid power locomotive and a medium, and belongs to the field of hydrogen fuel hybrid power locomotives. The method comprises the steps that when it is detected that a switch of a hydrogen fuel system in the hydrogen fuel hybrid power locomotive is turned to a stop position, a shutdown instruction is sent to the hydrogen fuel system so as to cut off an air inlet valve of the hydrogen fuel system; using an auxiliary machine device of the hydrogen fuel system and/or an auxiliary machine device of the hydrogen fuel hybrid power locomotive and/or an energy storage device of the hydrogen fuel hybrid power locomotive to consume target energy generated by the hydrogen fuel system within the shutdown delay time; when the target energy is consumed completely, whether the hydrogen fuel system is shut down successfully or not is judged; and if the hydrogen fuel system is successfully shut down, a DC/DC converter of the hydrogen fuel hybrid power locomotive is shut down, and a main control loop of the hydrogen fuel hybrid power locomotive is shut down. By means of the method, the safety and reliability of the hydrogen fuel hybrid power locomotive during parking can be further improved.

    本申请公开了一种氢燃料混合动力机车的停机控制方法、装置、设备及介质,属于氢燃料混合动力机车领域。该方法包括:当检测到氢燃料混合动力机车中氢燃料系统的开关打到停止位时,则向氢燃料系统发送停机指令,以切断氢燃料系统的进气阀门;利用氢燃料系统的辅机装置和/或氢燃料混合动力机车的辅机装置和/或氢燃料混合动力机车的储能装置消耗氢燃料系统在停机延迟时间内所产生的目标能量;当目标能量消耗完毕时,则判断氢燃料系统是否成功停机;若氢燃料系统成功停机,则关断氢燃料混合动力机车的DC/DC变流器,并关断氢燃料混合动力机车的主控制回路。通过该方法可以进一步提高氢燃料混合动力机车在停车时的安全性与可靠性。
