步骤102，将当前未被占用的区段，确定为目标点亮区段。
具体的，本申请实施例提供的信号机灯丝状态监测方法，可以由本申请实施例提供的信号机灯丝状态监测装置执行，该装置可以被配置在任意联锁系统中，以对信号机的灯丝状态进行监测。
需要说明的是，各信号机所在各区段可以根据需要具体选择，比如可以是物理区段，也可以是根据需要划分的逻辑区段，只要保证使位于信号机所在各区段外的列车上的司机无法用肉眼察觉到信号机的亮灯状态即可。临界距离，理论上是以人能够正常目视到并可以做出准确判断的生理极限距离。
具体实现时，可以通过计轴检测、轨道电路定位等方式，确定当前联锁系统运行周期内各信号机所在区段是否被占用，从而将当前未被占用的区段，确定为目标点亮区段。
可以理解的是，本实施例中将未被占用的区段确定为目标点亮区段，从而使得运行在目标点亮区段外的列车上的司机无法用肉眼察觉到信号机的亮灯状态，从而避免了对司机产生干扰。
步骤103，驱动目标点亮区段内的目标信号机点亮。
步骤104，根据目标信号机的点亮状态，确定目标信号机的灯丝状态。
具体的，确定了目标点亮区段后，即可驱动目标点亮区段内的目标信号机点亮。若目标信号机被点亮，则可以确定目标信号机的灯丝正常；若目标信号机未被点亮，则可以确定目标信号机的灯丝异常。
具体实现时，可以对信号机的点亮驱动进行采集，从而根据采集结果，确定目标信号机的灯丝状态。比如，若信号机的灯丝正常时，采集结果为1，灯丝异常时，采集结果为0。则若通过采集，确定采集结果为0，则可以确定信号机的灯丝异常。
需要说明的是，联锁系统的运行周期通常很短，一般被配置为250毫秒(ms)，相应的，在当前周期内驱动目标信号机点亮的时间也很短，这就可能出现驱动目标信号机点亮时，还未采集到信号机的点灯驱动结果，目标信号机已从点灯状态转为灭灯状态的情况，从而导致对目标信号机的灯丝状态判断错误。那么，在本申请实施例中，可以使目标信号机点亮的时间稍长，从而避免信号灯点亮时间过短导致的信号机灯丝状态判断错误。
另外，考虑到驱动目标信号机点亮时，目标点亮区段外可能有列车正在靠近目标点亮区段，若目标信号机的点灯状态过长时，可能会造成靠近目标点亮区段的列车进入目标点亮区段后，目标信号机仍处于点灯状态，从而对列车行车造成影响。且目标信号机点亮的时间过 长会造成能量的过多消耗。在本申请实施例中，目标信号机点亮的时间不易过长。
在本申请实施例中，可以使目标信号机持续点亮两个联锁系统运行周期，即，步骤103，具体可以包括：驱动目标点亮区段内的目标信号机，并使所述目标信号机持续点亮两个联锁系统运行周期。从而可以使对目标信号机的灯丝状态的判断结果更准确可靠，同时不会对列车行车造成影响，且避免能量的过多消耗。采用两个周期，是为了保障能准确的采集到灯丝状态信息,例如，一个周期内如果丢包的话，则还有另一个周期内的数据。
进一步的，驱动目标信号机点亮的初期，点灯驱动回路的运行状态可能不稳定，从而易对目标信号机的灯丝状态的判断造成影响。因此，在本申请实施例中，为了使对目标信号机的灯丝状态的判断结果更准确可靠，可以在点灯驱动回路的运行状态稳定后，根据目标信号机的点亮状态，确定目标信号机的灯丝状态。即，步骤104可以包括：
根据目标信号机点亮后的第二个联锁系统运行周期内的点亮状态，确定目标信号机的灯丝状态。
具体的，在目标信号机点亮后的第二个联锁系统运行周期内，点灯驱动回路的运行状态趋于稳定，此时，可以对信号机的点灯驱动进行采集，以采集在第二个联锁系统运行周期时，目标信号机的点亮状态，从而根据采集结果，确定目标信号机的灯丝状态。
可以理解的是，本申请实施例提供的信号机灯丝状态监测方法，可以在联锁系统每个运行周期，对信号机灯丝状态进行监测，从而可以实现对信号机的灯丝状态的及时检查，提高了联锁系统的可靠性。
本申请实施例提供的信号机灯丝状态监测方法，可以在确定当前联锁系统运行周期内各信号机所在各区段的占用状态后，确定当前未被占用的区段，为目标点亮区段，然后驱动目标点亮区段内的目标信号机点亮，从而根据目标信号机的点亮状态，确定目标信号机的灯丝状态。由此，实现了对信号机灯丝状态的实时监测，提高了对信号机灯丝状态监测的及时性和可靠性，进而提高了联锁系统的可靠性。
通过上述分析可知，可以确定当前联锁系统运行周期各信号机所在各区段中，未被占用的区段为目标点亮区段，通过驱动目标点亮区段内的目标信号机点亮，从而根据目标信号机的点亮状态，确定目标信号机的灯丝状态。在实际运用中，当列车运行在非CBTC模式下时，信号机应从灭灯状态转换为点灯状态，而此时若将未被占用的区段中的信号机点亮，以进行灯丝状态的监测，就会对列车的运行产生影响。因此，本申请提供的信号机灯丝状态方法还可以通过图2所示的方式实现。下面结合图2，对上述情况进行详细说明。
图2是本申请另一个实施例的信号机灯丝状态监测方法的流程示意图。
如图2所示，该信号机灯丝状态监测方法，还可以包括：
步骤201，确定当前联锁系统运行周期内各信号机所在各区段的占用状态，其中各区段的长度，均大于肉眼可识别亮灯状态时的临界距离。
步骤202，将当前未被占用的区段，确定为目标点亮区段。
步骤203，判断当前位于未被占用的区段外的列车，是否运行在基于通信的列车控制系统模式下，若是，则执行步骤204，否则执行步骤206。
其中，未被占用的区段，即目标点亮区段。
步骤204，驱动目标点亮区段内的目标信号机，并使所述目标信号机持续点亮两个联锁系统运行周期。
步骤205，根据目标信号机点亮后的第二个联锁系统运行周期内的点亮状态，确定目标信号机的灯丝状态。
其中，上述步骤201-202，步骤204-205的具体实现过程及原理，可以参照上述实施例的详细描述，此处不作赘述。
步骤206，根据目标信号机的点灯驱动采集结果，确定目标信号机的灯丝状态。
具体的，若当前位于未被占用的区段外的列车，运行在CBTC模式下，则目标点亮区段内的目标信号机为灭灯状态，从而可以驱动目标信号机持续点亮两个联锁系统运行周期，以根据目标信号机点亮后的第二个联锁系统运行周期内的点亮状态，确定目标信号机的灯丝状态。
若当前位于未被占用的区段外的列车，运行在非CBTC模式下，则目标点亮区段内的目标信号机应从灭灯状态转换为点灯状态。此时，可以对目标信号机的点灯驱动进行采集，从而根据点灯驱动采集结果，确定目标信号机的灯丝状态。比如，若信号机的灯丝正常时，采集结果为1，灯丝异常时，采集结果为0。则若通过采集，确定采集结果为0，则可以确定信号机的灯丝异常。
进一步的，若确定其中一目标信号机的灯丝异常，则可以将该目标信号机的标识发送给区域控制器，以使区域控制器进行预警，从而工作人员可以及时对信号机进行修理。
另外，可以将灯丝异常的目标信号机的标识发送给区域控制器，从而在某列车需要根据灯丝异常的信号机的指示行车时，区域控制器可以根据当前的运行情况，向该列车发送控制指令，从而该列车可以根据控制指令行车，避免误闯信号灯等情况的发生，减少设备及人员的损失。
即，在本申请实施例中，还可以包括：
在确定其中一目标信号机的灯丝异常时，将该目标信号机的标识发送给区域控制器。
本申请实施例提供的信号机灯丝状态监测方法，首先确定当前联锁系统运行周期各信号机所在各区段的占用状态，然后将当前未被占用的区段，确定为目标点亮区段，若当前位于未被占用的区段外的列车，运行在CBTC模式下，则驱动目标点亮区段内的目标信号机，持续点亮两个联锁系统运行周期，从而根据目标信号机点亮后的第二个联锁系统运行周期内的点亮状态，确定目标信号机的灯丝状态，若当前位于未被占用的区段外的列车，运行在非CBTC模式下，则根据目标信号机的点灯驱动采集结果，确定目标信号机的灯丝状态。由此，实现了对信号机灯丝状态的实时监测，提高了对信号机灯丝状态监测的及时性和可靠性，进 而提高了联锁系统的可靠性。
