具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
实施例一
图1为本申请实施例一提供的列车控制器输入电路的故障检测方法的流程图，图2为本申请实施例一提供的列车控制器输入电路的结构示意图。本申请实施例提供的方法可以由控制器中的列车控制器输入电路的故障检测装置来执行，可以采用软件和/或硬件的方式来实现。
如图2所示，本实施例提供的列车控制器1具有两个信号输入端，两个信号输入端各自与一个响应开关相连，两个响应开关用于根据相同列车控制信号执行开闭动作。将两个响应开关分别称为：第一响应开关11和第二响应开关12。两个响应开关的一端分别与对应的信号输入端相连，两个响应开关的另一端均通过供电线路与电源连接，供电线路上设置有控制开关13，控制开关13可根据控制器1发出的信号执行相应的开闭操作。
根据上述控制器输入电路的结构，本实施例提供的故障检测方法包括如下几个步骤：
步骤101、控制器向控制开关发送关断指令，以断开两个响应开关所在的供电线路。
该关断指令由控制器1发出，可以在需要进行故障检测的时候发出，也可以按照设定周期发出，即：每隔设定周期进行一次故障检测。
控制器1向控制开关13发出关断指令，以使控制开关13动作，进而断开两个响应开关 的供电。控制开关13的供电断了，则控制器对应的信号输入端正常情况下应当接收到低电平信号。
步骤102、控制器获取与两个响应开关对应的信号输入端接收到的第一电平信号。
控制器1从两个信号输入端分别接收第一电平信号。正常情况下，两个信号输入端接收到的第一电平信号均为低电平。
步骤103、控制器判断两个信号输入端接收到的第一电平信号是否均为低电平，若是，则执行步骤105；若否，则执行步骤104。
步骤104、控制器产生故障信息。
若两个信号输入端接收到的第一电平信号中的至少一个不为低电平，即：其中一个或两个为高电平，则表明对应的连接线路出现故障，控制器1产生故障信息。
步骤105、控制器向控制开关发送接通指令，以接通两个响应开关所在的供电线路。
若两个信号输入端接收到的第一电平信号均为低电平，则控制器1向控制开关13发送接通指令，以恢复第一响应开关11和第二响应开关12的供电。
步骤106、控制器获取与两个响应开关对应的信号输入端接收到的第二电平信号。
当两条供电线路恢复供电之后，控制器3获取两个信号输入端接收到的第二电平信号。
步骤107、控制器根据两个信号输入端接收到的第二电平信号判断两个响应开关的跳变是否满足两个响应开关各自所对应的跳变规则，若否，则产生故障信息。
上述两个响应开关可以为均为常开开关或常闭开关，或者其中一个为常开开关，另一个为常闭开关。
常开开关和常闭开关均具有对应的跳变规则：
若响应开关为常开开关，当响应开关未接收到列车控制信号之前，响应开关为常开状态，对应的信号输入端接收到低电平信号；当响应开关接收到列车控制信号之后，响应开关闭合，则对应的信号输入端接收到高电平信号。
若响应开关为常闭开关，当响应开关未接收到列车控制信号之前，响应开关为常闭状态，对应的信号输入端接收到高电平信号；当响应开关接收到列车控制信号之后，响应开关断开，则对应的信号输入端接收到低电平信号。
控制器1根据两个信号输入端接收到的第二电平信号来判断电平跳变是否满足各响应开关对应的跳变规则，若满足，则表明无故障发生；若不满足，则表明连接线路有故障，控制器1需产生故障信息。
本实施例提供的技术方案，通过断开连接在控制器两个信号输入端的响应开关的供电，判断两个信号输入端所接收到的信号是否为低电平，若否，则表明有故障产生；若是，则恢复连接在控制器两个信号输入端的响应开关的供电，继续判断两个信号输入端所接收到的电平信号是否满足与响应开关对应的跳变规则，若不满足，则表明连接线路有故障产生。本实施例提供技术方案能够对控制器输入电路进行故障检测，以使控制器及时得知故障状态并进 行相应的故障处理，以提高列车控制系统的可靠性，进而提高列车行驶安全性。
实施例二
本实施例是在上述实施例的基础上，对列车控制器输入电路的故障检测方法进行优化：
图3为本申请实施例二提供的列车控制器输入电路的结构示意图。如图3所示，第一响应开关11和第二响应开关12均为常闭开关。
上述步骤107中，控制器根据两个信号输入端接收到的第二电平信号判断两个响应开关的跳变是否满足两个响应开关各自所对应的跳变规则，若否，则产生故障信息，具体可以为：
控制器判断两个信号输入端接收到的第二电平信号是否均为高电平，若是，则表明满足两个响应开关的跳变规则。若否，则表明接收到低电平的连接线路出现故障，则控制器产生故障信息。
进一步的，还可以获取两个响应开关在根据列车控制信号进行跳变之后，两个信号输入端接收到的第三电平信号，并判断两个第三电平信号是否为低电平，若是，则满足响应开关的跳变规则，若否，则表明连接线路有故障发生。
实施例三
本实施例是在上述实施例的基础上，对列车控制器输入电路的故障检测方法进行优化：
图4为本申请实施例三提供的列车控制器输入电路的结构示意图。如图4所示，第一响应开关11和第二响应开关12均为常开开关。
图5为本申请实施例三提供的故障检测方法中根据第二电平信号判断响应开关的跳变是否满足跳变规则的流程图。如图5所示，上述步骤107中，控制器根据两个信号输入端接收到的第二电平信号判断两个响应开关的跳变是否满足两个响应开关各自所对应的跳变规则，若否，则产生故障信息，具体可以包括如下几个步骤：
步骤1071a、控制器判断两个信号输入端接收到的第二电平信号是否均为低电平，若是，则执行步骤1073a；若否，则执行步骤1072a。
步骤1072a、控制器产生故障信息。
步骤1073a、控制器获取两个响应开关在根据相同列车控制信号执行开闭动作之后，与两个响应开关对应的信号输入端接收到的第三电平信号。
步骤1074a、判断两个信号输入端接收到的第三电平信号是否均为高电平，若否，则执行步骤1072a。
由于两个常开开关的供电线路断开后，对应信号输入端接收到的信号为低电平；而当供电线路恢复供电后，对应信号输入端接收到的信号仍然为低电平，此时是无法判断出两个响应开关所在的连接线路是否有故障。因此，需要执行步骤1073和步骤1074，在常开开关根据相同的列车控制信号执行开闭动作之后，判断对应信号输入端接收到的电平是否变为高电平，若是，则满足跳变规则；若否，则表明对应的连接线路有故障发生，控制器1可产生故障信息。
实施例四
本实施例是在上述实施例的基础上，对列车控制器输入电路的故障检测方法进行优化：
图6为本申请实施例四提供的列车控制器输入电路的结构示意图。如图4所示，两个响应开关中的其中一个响应开关为常开开关，另一个响应开关为常闭开关。例如：第一响应开关11为常开开关，第二响应开关12为常闭开关。
图7为本申请实施例四提供的故障检测方法中根据第二电平信号判断响应开关的跳变是否满足跳变规则的流程图。如图7所示，上述步骤107中，根据两个信号输入端接收到的第二电平信号判断两个响应开关的跳变是否满足两个响应开关各自所对应的跳变规则，若否，则产生故障信息，包括如下几个步骤：
步骤1071b、控制器判断两个信号输入端接收到的第二电平信号是否相异，若是，则执行步骤1073b；若否，则执行步骤1072b。
具体的，第一响应开关11为常开开关，在未接收到列车控制信号之前，对应信号输入端接收到的第二电平信号为低电平。第一响应开关11根据列车控制信号发生跳变之后，对应信号输入端接收到的第二电平信号为高电平。
第二响应开关12为常闭开关，在未接收到列车控制信号之前，对应信号输入端接收到的第二电平信号为高电平。第二响应开关12根据列车控制信号发生跳变之后，对应信号输入端接收到的第二电平信号为低电平。
则在正常情况下，两个信号输入端接收到的第二电平信号相异，若相同，则表明有故障发生。
步骤1072b、控制器产生故障信息。
步骤1073b、控制器获取两个响应开关在根据相同列车控制信号执行开闭动作之后，与两个响应开关对应的信号输入端接收到的第三电平信号。
步骤1074b、控制器判断两个信号输入端接收到的第三电平信号是否相异，若否，则执行步骤1072b。
进一步的，还可以执行步骤1073b和1074b，当两个响应开关根据列车控制信号执行开闭动作之后，在正常情况下，常开开关闭合，常闭开关断开，因此，两个信号输入端接收到的第三电平信号也是相异的。若两个第三电平信号相同，则表明有故障发生。

  12. 一种列车控制器输入电路的故障检测装置，其特征在于，所述控制器具有至少两个信号输入端，所述至少两个信号输入端中的每个与一个用于根据相同列车控制信号执行开闭动作的响应开关的一端连接，每个响应开关的另一端均通过供电线路与电源连接，所述供电线路上设置有控制开关；所述装置包括：
    关断指令发送模块，用于向所述控制开关发送关断指令，以断开所述供电线路；
    第一电平信号获取模块，用于获取所述每个信号输入端对应接收到的每个第一电平信号；
    第一电平信号判断模块，用于判断所述每个第一电平信号是否均为低电平，并在所述每个第一电平信号均为低电平时触发接通指令发送模块的操作，以及在所述每个第一电平信号中的至少一个为高电平时触发故障信息产生模块的操作；
    故障信息产生模块，用于产生故障信息；
    接通指令发送模块，用于向所述控制开关发送接通指令，以接通所述供电线路；
    第二电平信号获取模块，用于获取所述每个信号输入端对应接收到的每个第二电平信号；
    跳变规则判断模块，用于根据所述每个第二电平信号判断每个响应开关的跳变是否满足每个响应开关各自所对应的跳变规则，并在所述每个响应开关的跳变中的至少一个没有满足 对应的跳变规则时触发故障信息产生模块的操作。
