附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对现有技术和实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明提供的一种应用于轨道车辆的蹬车系统的结构示意图；
图2-1为本发明提供的一种动作执行机构以及蹬车梯的打开状态示意图；
图2-2为本发明提供的一种动作执行机构以及蹬车梯的收回状态示意图；
图3为本发明提供的另一种应用于轨道车辆的蹬车系统的结构示意图。
具体实施方式
本发明的核心是提供一种应用于轨道车辆的蹬车系统，降低了安全隐患，提高了自动化程度；本发明的另一核心是提供一种包括上述蹬车系统的轨道车辆，安全性以及自动化程度高。
为使本发明实施例的目的、技术方案和优点更加清楚，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。
请参考图1，图1为本发明提供的一种应用于轨道车辆的蹬车系统，包括控制模块1、与轨道车辆连接的蹬车梯3以及与蹬车梯连接的动作执行机构2；
控制模块1，用于当满足预设打开条件时生成第一打开信号并发送至动作执行机构2，当满足预设收回条件时，生成第一收回信号并发送至动作执行机构2；
动作执行机构2，用于在接收到第一打开信号后控制蹬车梯3打开至 轨道车辆车体外侧且不与轨道车辆车体平行，在接收到第一收回信号后控制蹬车梯3收回至轨道车辆底部。
考虑到现有技术中轨道车辆上设于司机室的蹬车梯3平行于车体侧壁，司乘人员在上下车的过程中身体须紧贴于车体侧壁，不易控制自身的重心从而存在较大的安全隐患，本发明中的蹬车梯3可以由控制模块1控制，在满足预设打开条件的情况下打开蹬车梯3至车体的外侧，在这种情况下上下车时不会存在控制不好重心的情况，提高了人们上下车过程中的安全性，同时，由于控制模块1能够在满足预设条件时打开或关闭蹬车梯3，提高了轨道车辆的自动化程度。
此外，本申请实施例中的蹬车系统也可用于乘客车厢上，当轨道车辆紧急停车，周围没有站台时，可利用本申请中的蹬车系统进行上下车。
具体的，控制模块1起到发送动作信号的作用，能够判断当前条件是否符合预设的打开与收回条件，如果符合的话则生成相应的第一打开信号或第一收回信号，其中，预设的打开收回条件可以包括一些基本的条件，例如，在蹬车梯3的打开范围内没有障碍物的阻挡等条件，预设的收回条件可以为当轨道车辆有速度时则生成收回信号；控制模块1可以由例如包括工控机的控制模块1来实现。
当然，预设的打开以及收回条件还可以为多种其他的情况，控制模块1也可以采用其他多种方式来实现，本发明在此不做限定。
为了更清楚地对本申请实施例进行说明，请参考图2-1和图2-2，图2-1为本发明提供的一种动作执行机构以及蹬车梯的打开状态示意图，图2-2为本发明提供的一种动作执行机构以及蹬车梯的收回状态示意图，包括：动作执行机构2以及蹬车梯3。
具体的，动作执行机构2在接收到第一打开信号时，对蹬车梯3进行打开控制，如图2-1所示，并在打开状态下为蹬车梯3提供足够的支撑力协助用户上下车，当动作执行机构2接收到第一收回信号时，控制蹬车梯3收回到如图2-2所示的位置，其中，蹬车梯3可以铰接在如图2-1以及图2-2所示的轨道车辆的底部，蹬车梯3可以在动作执行机构2的控制下围绕铰接点进行转动。这里的动作执行机构2以及蹬车梯3的布置以及两 者之间的连接可以根据不同轨道车辆的不同情况进行相应的设置，其中，蹬车梯3打开状态时梯身与车体侧壁的角度，以及蹬车梯3收回状态下的位置都可以进行预先设置调整，例如可以将打开角度设置为图2-1中的150°，最基本的原则是当蹬车梯3位于打开状态时位于车体外侧，这样人们在上下车过程中就不会因为身体紧贴车体侧壁而控制不好重心，当位于收回状态时，蹬车梯3应位于车体限界以内的位置，不会对车辆的安全运行造成影响。动作执行机构2可以有多种实现方式，例如液压伸缩缸，直线电机等。
具体的，蹬车梯3的作用为为人们的上下车提供帮助，可以为各种不同材质，不同形状的梯子，本发明在此不做限定。
本发明提供了一种应用于轨道车辆的蹬车系统，包括控制模块、与轨道车辆连接的蹬车梯以及与蹬车梯连接的动作执行机构；控制模块，用于当满足预设打开条件时生成第一打开信号并发送至动作执行机构，当满足预设收回条件时，生成第一收回信号并发送至动作执行机构；动作执行机构，用于在接收到第一打开信号后控制蹬车梯打开至轨道车辆车体外侧且不与轨道车辆车体平行，在接收到第一收回信号后控制蹬车梯收回至轨道车辆底部。
可见，相对于现有技术中平行于车体侧壁设置的蹬车梯，本发明中的控制模块能够根据预设的打开条件以及收回条件生成第一打开信号或第一收回信号，通过控制动作执行机构来控制蹬车梯打开至轨道车辆的车体外侧且不与车体平行或收回至轨道车辆底部，蹬车梯处于车体外侧使人们在上下轨道车辆时能够很好地控制身体重心，降低了安全隐患，还提高了轨道车辆的自动化程度。
在上述实施例的基础上：
作为一种优选的实施例，控制模块1包括：
探测传感单元11，用于探测蹬车梯3伸出的预设范围内是否有障碍物，当没有探测到障碍物时，生成无障碍信号；
速度检测模块12，用于检测轨道车辆的速度，当轨道车辆速度为零时生成零速信号，当轨道车辆速度不为零时生成非零速信号；
逻辑控制单元13，用于当接收到无障碍信号以及零速信号时生成第一打开信号并发送至动作执行机构2；
当接收到非零速信号时生成第一收回信号并发送至动作执行机构2。
本申请实施例为控制模块1的一种具体实现方式，其中，逻辑控制单元13可以为例如基于工控机设计的逻辑控制单元13，主要用于对当前条件进行判断，符合预设收回或打开条件时生成相应的第一打开信号或第一收回信号，相当于控制模块1的中枢。
具体的，本申请实施例中的当前条件的其中一种为探测传感单元11探测的有无障碍物的结果，当没有障碍物时，会生成无障碍信号，另一种当前条件为速度检测模块12检测到的轨道车辆的速度信息，当轨道车辆速度为零时生成零速信号，当轨道车辆速度不为零时生成非零速信号，逻辑控制单元13会对上述的当前条件与预设的打开条件以及收回条件进行对比，当符合条件时生成相应的信号，在本实施例中，当接收到无障碍信号以及零速信号时生成第一打开信号并发送至动作执行机构2，确保在轨道车辆零速时打开蹬车梯3，既保护了蹬车梯3，也确保了沿途行人以及设施的安全，确保在无障碍物时打开蹬车梯3，对蹬车梯3以及相关部件起到了保护作用。
具体的，探测传感单元11可以采用例如红外探测，超声波探测等方式，对蹬车梯3的打开范围内的障碍物进行探测，在没有探测到障碍物时生成无障碍信号，探测传感单元的探测范围可以根据不同的需求预先设置，当然，也可以在某一蹬车梯附近设置多个探测传感单元对障碍物进行检测，本发明在此不做限定；速度检测模块12可以为轨道车辆上已有的速度检测模块12，也可以为外加的速度检测模块12，本发明在此不做限定。
作为一种优选的实施例，控制模块1还包括：
控制开关14，用于用户通过其发送第二打开信号或第二收回信号至逻辑控制单元13；
则逻辑控制单元13具体用于：
当接收到零速信号、无障碍信号以及第二打开信号时，生成第一打开信号并发送至动作执行机构2；
当接收到第二收回信号以及非零速信号时，生成第一收回信号并发送至动作执行机构2。
具体的，本申请实施例中对当前条件判断的过程中增加了一个用户发送的第二打开信号或第二收回信号的判断，预设的打开条件为当接收到零速信号、无障碍信号以及第二打开信号时，生成第一打开信号；当接收到第二收回信号以及非零速信号时，生成第一收回信号，其中，增加了第二打开信号的判断的结果为在轨道车辆没有速度且没有障碍物的情况下，还需要用户手动发出第二打开信号，才会生成第一打开信号，在轨道车辆速度不为零的情况下，需要用户手动发送第二收回信号才会生成第一收回信号，此种做法的好处在于提高了安全性，防止造成意外事故。
其中，控制开关14可以为多种不同类型的开关，本发明在此不做限定。
作为一种优选的实施例，探测传感单元11还用于：
当探测到障碍物时，生成障碍信号；
则逻辑控制单元13还用于：
当接收到零速信号、障碍信号以及第二打开信号时，发送障碍信号至外部显示器4；
当接收到非零速信号以及第二打开信号时，将非零速信号发送至外部显示器4；
则系统还包括：
外部显示器4，用于接收障碍信号或非零速信号并显示。
为了更清楚地对本申请实施例进行说明，请参考图3，图3为本发明提供的另一种应用于轨道车辆的蹬车系统的结构示意图，包括：控制模块1、动作执行机构2、蹬车梯3以及外部显示器4，其中，控制模块1具体包括探测传感单元11、速度检测模块12、逻辑控制单元13以及控制开关14。
本申请实施例具有外部显示器4这一装置，其作用在于，可以对该系统当前的故障以及相应的状态信息进行显示，逻辑控制单元13当接收到零 速信号、障碍信号以及第二打开信号时，发送障碍信号至外部显示器4；当接收到非零速信号以及第二打开信号时，将非零速信号发送至外部显示器4，用户通过外部显示器4便可快速得知不能执行打开操作的原因，以便于做出相对应的处理。
具体的，本发明对外部显示器4的类型不做限定，可以为电脑显示器，也可以为具有蜂鸣装置的显示器，以便于提示用户。
作为一种优选的实施例，动作执行机构2还用于：
当自身处于打开状态时生成打开状态信号，当自身处于收回状态时生成收回状态信号；
则逻辑控制单元13还用于：
将接收到的打开状态信号或收回状态信号发送至外部显示器4；
若接收到非零速信号时没有接收到收回状态信号，生成未完全收回信号并发送至外部显示器4。
具体的，动作执行机构2还可以生成对应打开或收回状态的打开状态信号或收回状态信号，这可以由例如动作执行机构2内部的位置传感器实现，本发明在此不做限定。
具体的，逻辑控制单元将上述的打开状态信号或收回状态信号发送至外部显示器4，便于用户了解蹬车梯3的位置；若接收到非零速信号时没有接收到收回状态信号，生成未完全收回信号并发送至外部显示器4，对运行中打开的蹬车梯3状态进行提示，免发生意外事故，提高了轨道车辆运行的安全性，自动化程度较高。
作为一种优选的实施例，逻辑控制单元13还用于：
当接收到零速信号、无障碍信号以及打开状态信号时，生成牵引封锁信号并发送至轨道车辆的牵引控制模块1；
当接收到非零速信号时没有接收到收回状态信号，生成牵引封锁信号以及制动信号并发送至牵引控制模块1。
当接收到收回状态信号时，则停止发送牵引封锁信号，或停止发送牵引封锁信号和制动信号。
具体的，在轨道车辆停止且无障碍物的前提下打开蹬车梯3后，逻辑控制单元13会生成牵引封锁信号，对轨道车辆的启动进行限制，以免发生意外的危险，提高了轨道车辆的安全性；在轨道车辆的运行过程中如果检测到蹬车梯3没有收回，则会对轨道车辆采取制动和牵引封锁的措施，以免对蹬车梯3造成损坏或者对沿途的人或物造成破坏。
作为一种优选的实施例，探测传感单元11为超声波探测器。
具体的，超声波探测器具有安装、调试简单，维修、保养方便，测量精度高等优点。
当然，除了超声波探测器外，探测传感单元11也可以采用其他类型的探测装置，本发明在此不做限定。
作为一种优选的实施例，控制开关14包括：
设于司机室内部的第一控制开关和/或设于司机室外部的第二控制开关。
具体的，在司机室内部与司机室外部设置控制开关14起到了冗余的作用增强了系统的可靠性，当其中第一控制开关发生故障的情况下，可以使用第二控制开关进行操作，此外，设置在司机室内部的第一控制开关可以在下车时进行操作，在上车时可以操作司机室外部的第二控制开关打开蹬车梯3，使用起来比较方便。
作为一种优选的实施例，动作执行机构2为直线电机。
具体的，直线电机具有结构简单、易于调节控制以及加速度高等优点。
当然，动作执行机构2也可以为其他种类的能够控制蹬车梯3在两个位置切换的装置，例如液压伸缩缸等，本发明在此不做限定。
