本申请实施例的列车行驶提示方法及装置，适用于辅助司机驾驶列车，使列车在利用车载储能装置作为动力源行驶时停止在方便救援的位置。
在本申请实施例中，通过基于车载储能装置中当前剩余储能和列车当前运行的线路的线路信息，从列车当前运行的线路中确定列车在当前剩余储能耗尽之前能到达且适合列车停靠的位置，将此位置作为最佳停车地点，并提示出该最佳停车地点，以辅助司机驾驶列车，避免将列车停止在不便救援的地方。
为了便于理解，先对本申请的方案所适用的系统进行介绍。本申请的方案所适用的系统可以称为UAS系统，如，参见图1，其示出了本申请一种列车行驶提示方法所适用的一种系统的组成架构示意图。
在图1所示的系统100中包括：储能检测装置101、至少一个传感器102、显示屏幕103、输入设备104和处理器105。其中储能检测装置101、传感器102、显示器103和输入设备104分别与处理器105通过数据连接。
其中，储能检测装置101用于检测列车上的车载储能装置的剩余储能。列车上的车载储能装置用于储存电能，在列车的供电电网发生故障时，为列车提供所需要的能量。处理器105通过储能检测装置101与处理器105之间的数据连接可以获取到车载储能装置的剩余储能。
可以理解的是，在车载储能装置内置有储能检测装置的情况下，系统100可以不包括储能检测装置，直接将处理器105与车载储能装置相连来获取到车载储能装置的剩余储能。
传感器102可以包括天线、速度传感器、位置传感器等等，用于检测列车运行相关的各种信息，如线路信息、运行速度、列车位置等。处理器105通过传感器102与处理器105之间的数据连接可以获取到传感器检测到的列车运行相关的各种信息。
显示屏幕103可以作为HMI，用于输出提示信息，如输出停车位置、行驶速度、列车运行信息等，以便驾驶列车的司机根据提示信息驾驶列车，还可以用于获取用户通过输入设备输入的操作信息，如接收用户选择进入提示模式的操作信息，以便处理器响应用户操作。
输入设备104用于接收用户输入的操作信息等。
显示屏幕103和输入设备104可以为触摸屏。
可以理解的是，系统100可以是列车上新增的独立系统；也可以是由列车上已有设备组合形成。
下面结合流程图对本申请实施例中列车行驶提示方法进行介绍。如，参见图2，其示出了本申请列车行驶提示方法一个实施例的流程示意图，本实施例 的方法可以应用于上述系统100中的处理器，该方法可在供电网发生停电故障时执行，可以包括：
S201，获取列车的车载储能装置中当前剩余储能。
其中，步骤S201可以在检测到供电网发生停电故障时立即自动执行，也可以基于用户操作触发执行。在一种可能的实现中，在检测到供电网发生停电故障时，系统会通过显示屏幕输出提醒用户选择是否进入提示模式的信息，在接收到用户选择进入提示模式的情况下，触发步骤S201执行。
可以理解的是，在供电网发生停电故障时，列车所需要的所有能量，包括列车行驶、空调、广播等，都由车载储能装置提供。通常列车会实现预留一定比例的电能用于列车行驶。其中，步骤201中获取的车载储能装置中当前剩余储能指的是列车预留的用于列车行驶的电能中的电能。
S202，获取列车当前运行的线路的线路信息。
其中，列车是在规划好的线路上运行的，线路信息指的是线路条件，可以是上坡、下坡、平路、弯道、隧道，还可以包括：线路周围的环境状况，如，线路路段周围是否临山、线路是否为单路段等等。列车在不同的线路条件下行驶所需要的电能是不同的，基于列车的线路信息既可以确定出列车运行所需消耗的能耗，又可以用于辅助选取适合停靠的位置点。
S203，基于当前剩余储能和线路信息，从列车当前运行的线路中，确定最佳停车地点。
其中，最佳停车地点为列车在当前剩余储能耗尽之前能到达且适合列车停靠的位置，可以为站点，也可以为区间内非隧道、非山洞、坡底等位置。
其中，确定最佳停车地点可以有多种可能的实现方式。在一种可能的实现中，可以先根据当前剩余的储能和线路信息能够确定出列车最远能够运行到的位置，在列车当前位置和最远能够运行到的位置之间的线路上选择一个位置作为最佳停车地点。在另一种可能的实现中，可以先在线路上确定一个位置，如某一个站点，然后根据当前剩余的储能和线路信息判断能否到达该位置，如果能，将该位置作为最佳停车地点。
S204，提示出该最佳停车地点。
如，在界面中输出该最佳停车点的具体位置信息，还可以输出该最佳停车点距离当前位置的距离等。
可以理解的是，最佳停车地点可以是便于进行启动应急走行的地点，还可以是最终想要到达的地点。
为了使司机了解列车的当前运行状态，在一种可能的实现中，除了提示出最佳停车地点，还可以获取表征列车当前运行状态的运行信息，提示出运行信息。
其中，运行信息包括：列车运行方向、允许运行时间、允许运行能耗和预计剩余电量。其中允许运行时间指的是列车在当前剩余储能下能够运行的时间，可以根据当前剩余储能以及列车各项能耗进行估算得到。允许运行能耗指的是列车预留的用于列车行驶的电能中的电能，可以通过储能检测装置获取到。预计剩余电量指的是列车到达最佳停车地点之后还剩余的电量，可以在确定出最佳停车地点之后根据列车行驶的运行能耗估算得到。运行信息还包括：当前列车速度、当前列车公里标、当前列车工况、当前剩余电量、当前运行功率等。其中，当前列车工况可以是制动行驶、惰行行驶和牵引行驶中的一种。
上述这些运行信息在列车运行过程中是会发生变化的，为了准确反映列车的运行情况，系统会在后台实时更新这些运行信息，确保提示出的运行信息为当前列车状态下的信息。
在本申请实施例中，通过基于车载储能装置中当前剩余储能和列车当前运行的线路的线路信息，从列车当前运行的线路中确定列车在当前剩余储能耗尽之前能到达且适合列车停靠的位置，将此位置作为最佳停车地点，并提示出该最佳停车地点，以辅助司机驾驶列车，避免将列车停止在不便救援的地方。
为了更好的辅助司机驾驶列车，除了提示出最佳停车地点和列车运行信息，还可以提示出建议行驶方案。参见图3，其示出了本申请列车行驶提示方法的又一个实施例的流程示意图，该方法包括：
S301，获取列车的车载储能装置中当前剩余储能。
S302，获取列车当前运行的线路的线路信息。
S303，基于当前剩余储能和线路信息，从列车当前运行的线路中，确定最佳停车地点，其中，最佳停车地点为列车在当前剩余储能耗尽之前能到达且适合列车停靠的位置。
S304，提示出最佳停车地点。
S305，获取表征列车当前运行状态的运行信息。
S306，提示出运行信息。
其中，步骤S305可以在步骤S304之前执行，也可以在步骤S304之后执行。步骤S306和步骤S304可以同时执行，也可以在步骤S304之后执行。
其中，步骤S301～S306可参见上面的实施例的介绍，此处不再赘述。
S307，根据当前剩余储能、列车当前运行的线路的线路信息和最佳停车地点，确定列车行驶的建议工况，生成建议行驶方案。
其中，生成的建议行驶方案至少包括建议工况。
其中，建议行驶方案可以是建议停车方案，建议工况包括：惰行行驶或制动行驶，生成的建议行驶方案还包括：建议行驶速度。建议行驶方案还可以是建议应急走行方案，建议工况包括：惰行行驶、制动行驶和牵引行驶中的一种，生成的建议行驶方案还包括：建议行驶速度和建议行驶方向。
S308，提示出生成的建议行驶方案。
其中，生成建议行驶方案之后还可以得到一些有助于司机驾驶列车行驶的信息，如预计到达时间、剩余行驶时间和剩余行驶距离，其中，预计到达时间是指列车按照建议行驶速度行驶到达最佳停车地点的时间点，如列车将在下午3点到达最佳停车地点。剩余行驶时间是指列车按照建议行驶速度行驶到达最佳停车地点还需行驶的时间，如列车还需行驶20分钟到达最佳停车地点。剩余行驶距离是指列车到达最佳停车地点还需行驶的距离，如列车还需行驶20千米到达最佳停车地点。在一种可能的实现中，可以基于建议行驶速度和最佳停车地点与当前位置的距离计算出预计到达时间、剩余行驶时间和剩余行驶距离，然后将预计到达时间、剩余行驶时间和剩余行驶距离也提示出来。
由于剩余行驶距离和剩余行驶时间会随着列车行驶实时变化，为了确保提示信息的准确性，在一种可能的实现中，系统会在后台实时更新剩余行驶时间 和剩余行驶距离，确保提示出的剩余行驶时间和剩余行驶距离为当前列车状态下的信息。
本申请实施例中，在提示出最佳停车地点和列车运行参数的基础上，还提示出了建议行驶方案，即给出了具体的行驶建议，司机可以按照具体的行驶建议驾驶列车行驶。
在司机按照具体的形式建议驾驶列车行驶的一种可能的实现中，在提示出建议行驶方案的同时，系统会通过显示屏幕输出提醒司机确认建议行驶方案行驶的信息，在接收到用户确认建议行驶方案的情况下，控制列车按照建议行驶方案行驶。
可以理解的是，列车的工况以及行驶速度会直接影响列车的运行能耗，为了确保列车能够到达最佳停车地点，在车载储能装置中当前剩余储能较少的时候，可以重新生成建议行驶方案，建议司机以节能的方式行驶。在一种可能的实现中，在列车按照建议行驶方案行驶的过程中，按照预设周期检测所述车载储能装置中当前剩余储能；在当前剩余储能低于预设值时，根据当前剩余储能和列车当前运行的线路的线路信息，确定列车行驶至最佳停车地点的建议工况，生成新的建议行驶方案，并提示出该新的建议行驶方案。
为了便于理解，下面结合司机驾驶列车行驶的具体应用场景对本申请实施例中列车行驶提示方法进行介绍，列车在供电网发生停电故障时，可能会经历三个阶段：第一个阶段下列车会停在某个位置，可以称作停车阶段；第二个阶段下为列车应急行驶做准备，可以称作停车准备阶段；第三个阶段下列车进行应急行驶，可以称为应急行驶阶段。
参见图4，其示出了本申请列车行驶提示的又一个实施例的流程示意图，应用于上面提到的UAS系统，该方法包括：
S401，在检测到供电网发生停电故障时，列车进入停车阶段，UAS系统通过HMI提醒司机选择是否进入提示模式。进入提示模式，也就是使UAS系统处于工作模式，否则UAS仍处于热备模式。
S402，通过HMI获取司机选择，在司机选择了进入提示模式的情况下，执行步骤S403；在司机选择了不进入提示模式的情况下，结束流程。
S403，获取列车的车载储能装置中当前剩余储能。
S404，获取列车当前运行的线路的线路信息。
S405，基于当前剩余储能和线路信息，从列车当前运行的线路中，确定最佳停车地点。
可以理解的是，步骤S405中确定出的最佳停车地点是在制动或惰行工况下可以到达的位置，该位置需要便于后续列车启动进行应急走行。
S406，获取表征列车当前运行状态的运行信息，并在后台实时更新该运行信息，其中，运行信息至少包括：列车运行方向、允许运行时间、允许运行能耗和预计剩余电量。
S407，根据当前剩余储能、列车当前运行的线路的线路信息和最佳停车地点，确定列车行驶的建议工况，生成建议行驶方案，其中，建议工况可以是制动行驶或惰行行驶，生成的建议行驶方案还包括：建议行驶速度。
S408，获取预计到达时间、剩余行驶时间和剩余行驶距离。
S409，通过HMI提示出最佳停车地点、建议行驶方案、运行信息、预计到达时间、剩余行驶时间和剩余行驶距离。
在列车停止在最佳停车地点后，进入停车准备阶段。UAS系统执行步骤：
S410，获取列车的车载储能装置中当前剩余储能。
S411，获取列车当前运行的线路的线路信息。
S412，基于当前剩余储能和线路信息，从列车当前运行的线路中，确定应急走行最终的最佳停车地点。
可以理解的是，步骤S412中确定出的最佳停车地点是列车在停车阶段停车后，再启动进行应急走行时最终想要到达的地点。
S413，根据当前剩余储能、列车当前运行的线路的线路信息和最佳停车地点，确定列车应急行驶的建议工况，生成建议行驶方案。其中，建议工况可以是制动行驶、惰行行驶和牵引行驶中的一种，生成的建议行驶方案还包括：建议行驶速度和建议行驶方向。
S414，获取预计到达时间、剩余行驶时间和剩余行驶距离。
S415，通过HMI提示出最佳停车地点、建议行驶方案、预计到达时间、剩余行驶时间和剩余行驶距离。
可以理解的是，由于运行信息是实时更新显示的，所以在显示最终的最佳停车地点、建议行驶方案、预计到达时间、剩余行驶时间和剩余行驶距离时，运行信息也同时有显示。
S416，通过HMI提醒司机确认是否以建议行驶方案行驶。
S417，通过HMI获取司机确认信息，在司机确认以建议行驶方案行驶时，控制列车按照建议行驶方案中的建议工况行驶，以在预计到达时间到达该最佳停车地点。
S418，在列车以建议行驶方案行驶的过程中，检测车载储能装置中当前剩余储能。
S419，在当前剩余储能低于预设值时，重新执行步骤S413～S418。
其中，步骤S416～S419属于应急行驶阶段。
可以理解的是，列车在供电网发生停电故障时，可能已经距离站点很近，通过惰行行驶或制动行驶即可到达站点，此时列车只经历停车阶段，无需经历停车准备阶段和应急行驶阶段。
