技术领域
本发明涉及氢燃料混合动力机车领域，特别涉及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。

可见，在本发明所提供的停机控制方法中，当氢燃料混合动力机车中的TCMS检测到氢燃料混合动力机车中氢燃料系统的开关打到停机位时，首先是向氢燃料系统发送停机指令，以让氢燃料系统切断其进气阀门；同时，TCMS还会控制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来消耗氢燃料系统在停机延迟时间内所产生的目标能量。当氢燃料系统在停机延迟时间内所产生的目标能量消耗完毕时，则判断氢燃料系统是否成功停机，如果氢燃料系统成功停机，则TCMS会同时关断氢燃料混合动力机车的DC/DC变流器以及氢燃料混合动力机车的主控制回路。相较于现有技术而言，由于本发明所提供的停机控制方法充分考虑了氢燃料系统的停机延迟特性，只有在氢燃料系统在停机延迟时间内所产生的目标能量全部消耗完毕时，TCMS才会切断氢燃料混合动力机车中的DC/DC变流器和主控制回路，这样就可以避免氢燃料混合动力机车在停机过程中所出现的过温、过压与过流等故障，由此就可以进一步保证氢燃料混合动力机车在停机时的安全性与可靠性。相应的，本发明所提供的一种氢燃料混合动力机车的停机控制装置、设备及介质，同样具有上述有益效果。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参见图1，图1为本发明实施例所提供的一种氢燃料混合动力机车的停机控制方法的流程图，该方法包括：
步骤S11：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；
步骤S12：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；
步骤S13：当目标能量消耗完毕时，则判断氢燃料系统是否成功停机；
步骤S14：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。
在本实施例中，是提供了一种氢燃料混合动力机车的停机控制方法，利用该方法来对氢燃料混合动力机车进行停机控制，可以进一步提高氢燃料混合动力机车在停机时的安全性与可靠性。该停机控制方法是以氢燃料混合动力机车中的TCMS(Train Control and Management System，列车控制和管理系统)为执行主体进行具体说明。
请参见图2和图3，图2为本发明实施例所提供的一种氢燃料混合动力机车的供电原理示意图；图3为本发明实施例所提供的一种氢燃料混合动力机车的供电回路示意图。在图2和图3中，101表示氢燃料混合动力机车中的氢燃料系统、102表示氢燃料混合动力机车中的DC/DC(直流-直流)变流器、103表示氢燃料混合动力机车中的直流母线电路、104表示氢燃料混合动力机车中的储能装置、105表示氢燃料混合动力机车中的辅助变流器、106表示负载、K1表示氢燃料混合动力机车中主控制回路的控制开关、K2表示氢燃料混合动力机车中氢燃料系统输出回路的控制开关。
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机位时，则说明氢燃料混合动力机车发生了故障，需要停机才能保证氢燃料混合动力机车的安全性。此时，氢燃料混合动力机车中的TCMS需要向氢燃料混合动力机车中的氢燃料系统发送停机指令，当氢燃料系统接收到TCMS所发送的停机指令时，氢燃料系统会将其自身的进气阀门关断，从而禁止氢气再进入到氢燃料系统的反应堆里。
因为氢燃料系统的停机响应时间较慢，其停机操作具有延迟停机特性，所以，氢燃料系统在接收到TCMS所发送的停机指令时，其内部还会具有一定量的氢气产生能量。为了避免氢燃料混合动力机车出现过压、过温以及过流等故障，此时就需要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来消耗氢燃料系统在停机延时时间内所产生的目标能量。
需要说明的是，在本实施例中，氢燃料系统的辅机装置包括但不限于氢燃料系统的空调、压缩机以及负载等设备，同时氢燃料混合动力机车的 辅机装置也包括但不限于氢燃料混合动力机车的制冷系统、压缩机等设备。
当使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将氢燃料系统在停机延迟时间内所产生的目标能量消耗完毕时，氢燃料混合动力机车中的TCMS就会判断是否会接收到氢燃料系统成功停机的反馈信号。
如果氢燃料混合动力机车中的TCMS接收到了氢燃料系所反馈的成功停机的信号，则说明氢燃料系统已经成功停机，此时TCMS就会关断氢燃料混合动力机车中的DC/DC变流器，同时还会关断氢燃料混合动力机车的主控制回路。如果TCMS没有接收到氢燃料系统所反馈的成功停机的信号，则说明氢燃料系统停机失败，此时TCMS就会提示预警信息来提醒工作人员的注意，从而避免安全事故的发生。
需要说明的是，在实际应用中，氢燃料系统是否成功停机是通过氢燃料系统输出回路上的控制开关来判断。也即，如果氢燃料系统输出回路上的控制开关处于关断状态，则说明氢燃料系统已经成功停机；如果氢燃料系统输出回路上的控制开关处于导通状态，则说明氢燃料系统停机失败。
显然，由于本实施例所提供的停机控制方法充分考虑了氢燃料系统的停机延迟特性，只有在氢燃料系统在停机延迟时间内所产生的目标能量全部消耗完毕时，TCMS才会切断氢燃料混合动力机车中的DC/DC变流器和主控制回路，通过这样的设置方式就可以避免氢燃料混合动力机车在停机过程中所出现的过温、过压与过流等故障，所以，通过本实施例所提供的停机控制方法就可以进一步保证氢燃料混合动力机车在停机时的安全性与可靠性。
可见，在本实施例所提供的停机控制方法中，当氢燃料混合动力机车中的TCMS检测到氢燃料混合动力机车中氢燃料系统的开关打到停机位时，首先是向氢燃料系统发送停机指令，以让氢燃料系统切断其进气阀门；同时，TCMS还会控制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来消耗氢燃料系统在停机延迟时间内所产生的目标能量。当氢燃料系统在停机延迟时间内所产生的目标能量消耗完毕时，则判断氢燃料系统是否成功停机，如果氢燃料系统 成功停机，则TCMS会同时关断氢燃料混合动力机车的DC/DC变流器以及氢燃料混合动力机车的主控制回路。相较于现有技术而言，由于本实施例所提供的停机控制方法充分考虑了氢燃料系统的停机延迟特性，只有在氢燃料系统在停机延迟时间内所产生的目标能量全部消耗完毕时，TCMS才会切断氢燃料混合动力机车中的DC/DC变流器和主控制回路，这样就可以避免氢燃料混合动力机车在停机过程中所出现的过温、过压与过流等故障，由此就可以进一步保证氢燃料混合动力机车在停机时的安全性与可靠性。
基于上述实施例，本实施例对技术方案作进一步的说明与优化，作为一种优选的实施方式，上述步骤：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的过程，包括：
在氢燃料系统单独向氢燃料混合动力机车进行供电，或者氢燃料系统和储能装置共同向氢燃料混合动力机车进行供电的情形下，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。
可以理解的是，氢燃料混合动力机车在运行过程中，既可以使用氢燃料系统为其进行供电，也可以使用氢燃料系统和氢燃料混合动力机车中的储能装置共同来向氢燃料混合动力机车进行供电。
因此，氢燃料混合动力机车中的TCMS在检测氢燃料混合动力机车中氢燃料系统的开关状态时，既可以是在氢燃料系统单独向氢燃料混合动力机车进行供电的情形下来检测氢燃料系统的开关状态，也可以是在氢燃料系统和氢燃料混合动力机车的储能装置共同向氢燃料混合动力机车进行供电的情形下来检测氢燃料系统的开关状态。
显然，通过本实施例所提供的技术方案，就可以保证氢燃料混合动力机车中的TCMS在发送停机指令时的可靠性与全面性。
基于上述实施例，本实施例对技术方案作进一步的说明与优化，作为一种优选的实施方式，上述步骤：断氢燃料系统是否成功停机的过程之后， 还包括：
若氢燃料系统停机失败，则提示预警信息。
在实际应用中，如果氢燃料混合动力机车中的TCMS判断出氢燃料系统在接收到停机指令之后，氢燃料系统停机失败，此时为了工作人员能够及时知悉到氢燃料系统的工作状态，TCMS就可以以提示预警信息的方式来提醒工作人员的注意，从而使得工作人员可以对氢燃料系统及时采取相应的补救措施来避免安全事故的发生。
可见，通过本实施例所提供的技术方案，就可以进一步保证氢燃料混合动力机车在停机过程中的整体可靠性。
基于上述实施例，本实施例对技术方案作进一步的说明与优化，作为一种优选的实施方式，上述步骤：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的过程，包括：
判断氢燃料系统在停机延迟时间内所产生的目标能量是否小于或等于预设阈值；
若目标能量小于或等于预设阈值，则利用氢燃料系统的辅机装置消耗目标能量；
若目标能量大于预设阈值，则利用DC/DC变流器对目标能量进行正向升压处理，并判断氢燃料混合动力机车中的直流母线电压是否小于或等于氢燃料混合动力机车的过压保护阈值；
若氢燃料混合动力机车中的直流母线电压小于或等于氢燃料混合动力机车的过压保护阈值，则利用氢燃料混合动力机车的辅机装置消耗目标能量；
若氢燃料混合动力机车中的直流母线电压大于氢燃料混合动力机车的过压保护阈值，则利用储能装置消耗目标能量。
在本实施例中，在使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来消耗氢燃料系统在停机延迟时间内所产生的目标能量时，可以根据氢燃料系统在停机延迟时 间内所产生能量的大小来决定到底是采用哪种方式来消耗氢燃料系统在停机延迟时间内所产生的目标能量。
具体的，如果氢燃料系统在停机延迟时间内所产生的目标能量小于或等于预设阈值，则说明氢燃料系统在停机延迟时间内所产生的能量较少，此时就可以利用氢燃料系统的辅机装置来消耗氢燃料系统在停机延迟时间内所产生的目标能量，以将氢燃料系统在停机延迟时间内所产生的能量消耗在氢燃料系统的内部。
如果氢燃系统在停机延时时间内所产生的目标能量大于预设阈值，则说明氢燃料系统不能够完全消耗氢燃料系统在停机延迟时间内所产生的目标能量。此时就需要利用氢燃料混合动力机车中的DC/DC变流器对目标能量进行正向升压处理，并判断氢燃料混合动力机车中的直流母线电压是否小于或等于氢燃料混合动力机车的过压保护阈值。
如果氢燃料混合动力机车中的直流母线电压小于或等于氢燃料混合动力机车的过压保护阈值，则说明氢燃料混合动力机车的辅机装置可以将氢燃料系统在停机延迟时间内所产生的目标能量消耗完毕，此时只需使用氢燃料混合动力机车的辅机装置来消耗氢燃料系统在停机延迟时间内所产生的目标能量即可。如果氢燃料混合动力机车中的直流母线电压大于氢燃料混合动力机车的过压保护阈值，则说明氢燃料混合动力机车中的辅机装置并不能将氢燃料系统在延迟时间内所产生的目标能量消耗完毕，此时就需要利用氢燃料混合动力机车中的储能装置来消耗氢燃料系统在停机延迟时间内所产生的目标能量。
作为一种优选的实施方式，上述停机控制方法还包括：
若储能装置在预设时间内未将目标能量消耗完毕，则利用氢燃料混合动力机车的制动电阻消耗目标能量。
在通常情况下，使用氢燃料混合动力机车中的储能装置均可以将氢燃料系统在停机延迟时间内所产生的目标能量消耗完毕。但是，在本实施例中，为了进一步保证氢燃料混合动力机车在停机运行过程中的安全性，还可以继续判断氢燃料混合动力机车中的储能装置是否能够在预设时间内将氢燃料系统在停机延迟时间内所产生的目标能量消耗完毕，如果氢燃料混 合动力机车中的储能装置不能在预设时间内将氢燃料系统在停机延迟时间内所产生的目标能量消耗完毕，此时还可以使用氢燃料混合动力机车中的制动电阻来快速消耗氢燃料系统在停机延迟时间内所产生的目标能量。
作为一种优选的实施方式，上述步骤：利用储能装置消耗目标能量的过程，包括：
在斩波充电模式下利用氢燃料混合动力机车中的直流母线电压对储能装置进行充电，以利用储能装置消耗目标能量。
在使用氢燃料混合动力机车中的储能装置来消耗氢燃料系统在停机延迟时间内所产生的目标能量时，可以在斩波充电模式下利用氢燃料混合动力机车中的直流母线电压来对氢燃料混合动力机车中的储能装置进行充电，并利用氢燃料混合动力机车中的储能装置来消耗氢燃料系统在停机延迟时间内所产生的目标能量。
可以理解的是，采用斩波的方法对氢燃料混合动力机车中的储能装置进行充电，在此种充电方式下，通过开关管对储能装置的充电电流进行控制，使得开关管在开通一段时间后再关断一段时间，这样就能够达到循环往复地对储能装置进行充电的目的。在此充电模式下，就可以让储能装置中的充电离子有一个扩散的过程，这样就会显著增加储能装置的充电利用率，并由此改善储能装置的充电效果。
显然，通过本实施例所提供的技术方案，就可以对氢燃料系统在停机延迟时间内所产生的能量进行更好的消耗。
