Description

一种灵活编组的解编方法、设备和存储介质 技术领域
本申请涉及轨道交通技术领域，尤其涉及一种灵活编组的解编方法、系统、设备和存储介质。
背景技术
随着城市地铁交通规模的快速扩大，以及未来智能化的发展需求，对于车辆灵活编组以及智能重联提出了更高的需求，即车辆虚拟编组技术应用的呼声越来越高。
传统的地铁车辆一般为固定编组形式，根据不同时段客流量，可以通过车钩进行车辆的重联或解编操作，以满足不同的客流需求。传统的重联列车可以通过车钩来传递重联列车之间的纵向力，使列车保持同样的速度，同时通过车钩上的电气布线来传递前后车的相关车辆信息。但是传统的车钩重联解编操作比较繁琐，且耗费较多的人工及时间，极大程度上降低了整条线路的运营效率。
而虚拟编组是指将两列或多列车辆通过虚拟重联控制方式整合为一列车，不同于传统固定编组列车，列车与列车之间没有车钩，不需要人工参与，重联或解编均通过相关信号即可完成操作，极大地提高线路运营效率。
对于虚拟编组，因为其解编较为灵活，因此灵活编组的解编方法尤显重要。
发明内容
为了对灵活编组进行解编，本申请提供了一种灵活编组的解编方法、系统、设备和存储介质。
本申请第一个方面，提供了一种灵活编组的解编方法，所述方法包括：
确定解编条件被满足后，确定目标列车；

存储器；
处理器；以及
计算机程序；
其中，所述计算机程序存储在所述存储器中，并被配置为由所述处理器执行以实现如上述第一个方面所述的方法。
本申请第三个方面，提供了一种计算机可读存储介质，其上存储有计算机程序；所述计算机程序被处理器执行以实现如上述第一个方面所述的方法。
本申请在已完成虚拟编组的各列车运行线路不唯一，或者，与邻车通信中断，或者，接收到解编指令的情况下，会确定目标列车，并与目标列车进行解编，实现了灵活编组的解编。
附图说明
此处所说明的附图用来提供对本申请的进一步理解，构成本申请的一部分，本申请的示意性实施例及其说明用于解释本申请，并不构成对本申请的不当限定。在附图中：
图1为本申请实施例提供的一种灵活编组的解编方法的流程示意图。
具体实施方式
为了使本申请实施例中的技术方案及优点更加清楚明白，以下结合附图对本申请的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本申请的一部分实施例，而不是所有实施例的穷举。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在实现本申请的过程中，发明人发现，传统的地铁车辆一般为固定编组形式，根据不同时段客流量，可以通过车钩进行车辆的重联或解编操作，以满足不同的客流需求。传统的重联列车可以通过车钩来传递重联列车之间的纵向力，使列车保持同样的速度，同时通过车钩上的电气布线来传递前后车的相关车辆信息。但是传统的车钩重联解编操作比较繁琐，且耗费较多的人工及时间，极大程度上降低了整条线路的运营效率。
而虚拟编组是指将两列或多列车辆通过虚拟重联控制方式整合为一列车，不同于传统固定编组列车，列车与列车之间没有车钩，不需要人工参与，重联或解编均通过相关信号即可完成操作，极大地提高线路运营效率。
对于虚拟编组，因为其解编较为灵活，因此灵活编组的解编方法尤显重要。
基于此，本申请提供一种灵活编组的解编方法、设备和存储介质，该方法包括：确定解编条件被满足后，确定目标列车；与目标列车进行解编；解编条件为：已完成虚拟编组的各列车运行线路不唯一，或者，与邻车通信中断，或者，接收到解编指令。本申请提供的方法在已完成虚拟编组的各列车运行线路不唯一，或者，与邻车通信中断，或者，接收到解编指令的情况下，会确定目标列车，并与目标列车进行解编，实现了灵活编组的解编。
参见图1，本实施例提供的灵活编组的解编方法实现过程如下：
101，确定解编条件被满足后，确定目标列车。
其中，解编条件为：已完成虚拟编组的各列车运行线路不唯一(例如，编组列车将在不久之后运行在不同的线路上)，或者，与邻车通信中断，或者，接收到解编指令。
对于已完成虚拟编组的各列车运行线路不唯一的解编条件，其仅头车可能会满足，也就是说，只有头车才可能确定已完成虚拟编组的各列车运行线路不唯一的解编条件被满足。
对于接收到解编指令的解编条件，其仅非头车可能会满足，也就是说，只有非头车才可能确定接收到解编指令的解编条件被满足。
对于与邻车通信中断的解编条件，其既可以是头车能满足，也可以是非头车能满足，也就是说，头车可能确定与邻车通信中断的解编条件被满足，非头车也可能确定与邻车通信中断的解编条件被满足。
另外，确定目标列车的方案随着解编条件的不同而变化。
例如：
满足的解编条件为已完成虚拟编组的各列车运行线路不唯一时，确定目标列车的方案为：将运行路线不同的列车确定为目标列车。
满足的解编条件为接收到解编指令时，确定目标列车的方案为：将前一邻车确定为目标列车。
满足的解编条件为与邻车通信中断时，确定目标列车的方案为：将发送报文的邻车确定为目标列车。
其中，与邻车通信中断的确定方案为：连续接收到m个通信周期的报文均出现丢包，则确定与邻车通信中断，即确定解编条件被满足。
报文由同一邻车发送。m为预设的正整数。例如，m＝10，即连续10个通信周期的报均出现丢包。
丢包的情况可以为无法接收到报文，也可以为收到的报文中拓扑帧与本地拓扑帧不一致。
也就是说，连续m个通信周期均会出现无法接收到报文，或者收到的报文中拓扑帧与本地拓扑帧不一致。可以所有通信周期均无法接收到报文，也可以所有通信周期收到的报文中拓扑帧均与本地拓扑帧不一致，还可以部分周期通信周期无法接收到报文，部分周期通信周期收到的报文中拓扑帧与本地拓扑帧不一致。
其中，无法接收到的报文为拓扑帧报文或信息帧报文。
102，与目标列车进行解编。
本步骤的具体实现方案也随着解编条件的不同而变化。
●满足的解编条件为已完成虚拟编组的各列车运行线路不唯一时，
1.1监控与目标列车之间的距离。
具体实现时，可以先调整当前运行速度。此时，监控与目标列车之间的距离的实现方案为：根据当前运行速度，监控目标车辆与目标车辆前的邻车之间的距离。
1.2当与目标列车之间的距离达到达到临界通信距离时，与目标列车进行解编。
另外，临界通信距离为在任何情况下两列车都不会出现碰撞事故的距离，设前车为静止状态，此情况下计算出的两车距离最远，为最大常用制动距离与预设值的积。
以预设值为1.5为例，临界通信距离＝最大常用制动距离*1.5。
此外，在与目标列车进行解编时：
1)向目标车辆发送解编命令。
其中，解编命令用于指示目标车辆反馈响应帧。
2)接收到目标车辆反馈的响应帧后，设置拓扑帧中的初运行标志为禁止。
3)向目标车辆发送设置后的拓扑帧。设置后的拓扑帧用于指示目标车辆启动自动驾驶模式，完成解编。
●满足的解编条件为接收到解编指令时，
2.1向解编指令发送端反馈响应帧。
其中，响应帧用于指示解编指令发送端设置拓扑帧中的初运行标志为禁止，并发送设置后的拓扑帧。
2.2当接收到的拓扑帧中的初运行标志为禁止时，启动自动驾驶模式，完成解编。
●满足的解编条件为与邻车通信中断时，
3.1触发紧急制动。
3.2设置拓扑帧。
具体的，若当前无法接收到报文，则初始化拓扑帧。若当前接收到的报文中拓扑帧与本地拓扑帧不一致，则设置拓扑帧的初运行完成标志为未完成状态。
3.3启动自动驾驶模式。
本实施例提供的灵活编组的解编方法，列车(此时只能是头车)判断出编组列车将在不久之后运行在不同的线路上则头车要根据当前运行速度与解编后两车的运行距离差对后车进行运行控制使得两车之间的距离逐渐增大，当两车之间的距离达到临界通信距离时，列车(此时只能是头车)下发解编命令给后车，后车收到解编命令后返回响应帧，列车(此时只能是头车)收到响应帧后设置拓扑帧中初运行状态为禁止初运行，当后车收到禁止初运行的拓扑帧后启动自动驾驶模式完成解编。
两车之间的距离超过临界通信距离，两车各自恢复自动驾驶模式、初始化拓扑帧、初始化控制权状态。
当两车之间因其他原因导致拓扑帧或信息帧通信连续丢包超过10个时认为通信中断，在通信中断的条件下，接收不到报文的列车将本车拓扑帧初始化并改为自动驾驶模式，能收到报文的列车判断接收到的拓扑帧与本地拓扑帧不一致则设置初运行完成标志为未完成状态并且改为自动驾驶模式。
编组列车需要解编时，在精确定位手段探测到定位距离到达阈值前，前车优先使用精确定位手段、冗余使用列车定位计算两车间隔距离的方式获得两车间隔，前车控制行车间隔逐渐增大，超过精确定位手段探测到定位距离到达阈值后，列车使用列车定位计算两车间隔距离，继续控制两列车行车间隔达到编组通信临界距离后解编；解编后，后车执行完前车发的控制命令后，恢复自主运行。
需要说明的是，本实施例提供的方法针对的是已经建立灵活编组的列车组中的任一组列车，该列车可以为头车也可以为非头车。
该灵活编组的建立过程是通过列车、地面控制中心、数据交互中心实现的。
具体的，
401，列车实时向地面控制中心发送运行信息。
402，地面控制中心接收列车发送的运行信息。
403，地面控制中心将运行信息发送给数据交互中心。
404，数据交互中心接收地面控制中心发送的运行信息。
405，数据交互中心根据运行信息确定列车信息列表，并发送给列车。
具体的，
1、获取位置信息。
2、从位置信息和运行信息中识别出同一轨道上、同向行驶的列车。
3、根据识别到的列车确定列车信息列表。
4、将列车信息列表发送给列车。
406，列车中的任一列车(如第一列车)获取数据交互中心发送的列车信息列表。
其中，第一列车为任一组列车，该列车待进行灵活编组的建立。即，第一列车中的“第一”仅为标 识作用，为了区分其他列车，不具备任何其他含义。
407，第一列车根据列车信息列表与另一列车(如第二列车)进行通信。
其中，第二列车为除第一列车之外的任一组列车，该列车也待进行灵活编组的建立。即，第二列车中的“第二”仅为标识作用，为了区分其他列车，不具备任何其他含义。第二列车与第一列车为两组不同的列车，第一列车和第二列车需要进行建立灵活编组。
在执行步骤407时，第一列车会解析步骤406中收到的列车信息列表，得到列车数量。若列车数量大于1，且与第二列车之间的距离满足临界通信距离，则与第二列车进行通信。
其中，临界通信距离为在任何情况下两列车都不会出现碰撞事故的距离，设前车为静止状态，此情况下计算出的两车距离最远，为最大常用制动距离与预设值的积。
以预设值为1.5为例，临界通信距离＝最大常用制动距离*1.5。
408，第一列车基于通信，接收第二列车发送的第二拓扑帧。
其中，第二拓扑帧中的“第二”仅为标识作用，为了区分其他列车发送的拓扑帧，不具备任何其他含义。也就是说，第二拓扑帧是拓扑帧，是由第二列车发送的拓扑帧，即第二列车的拓扑帧。
另外，拓扑帧中包括初运行标志、IP地址列表、初运行完成标志等。
初运行标志用于描述所属列车是否禁止编组。
初运行完成标志用于描述所属列车是否完成初运行。
在步骤408中，除了基于通信，接收第二列车发送的第二拓扑帧，还会同时接收第二列车发送的第二信息帧。
其中，第二信息帧中的“第二”仅为标识作用，为了区分其他列车发送的信息帧，不具备任何其他含义。也就是说，第二信息帧是拓扑帧，是由第二列车发送的信息帧，即第二列车的信息帧。
409，第一列车根据第二拓扑帧建立灵活编组。
具体的，
1、确定运行曲线
●若根据第二拓扑帧确定不满足编组条件，则
1.1当第一列车位于第二列车前时，确定自动驾驶。
1.2当第一列车位于第二列车后时，根据第二列车的运行信息确定灵活编组的运行曲线。
由于拓扑帧中包括初运行标志，初运行标志用于描述所属列车是否禁止编组，因此根据第二拓扑帧确定不满足编组条件的具体判断方式为：
若第二拓扑帧的初运行标志为禁止(如即第二列车拒绝编组)，则确定不满足编组条件。
或者，
若第一列车的第一拓扑帧的初运行标志为禁止(如即第一列车拒绝编组)，则确定不满足编组条件。
其中，第一拓扑帧中的“第一”仅为标识作用，为了区分其他列车发送的拓扑帧，不具备任何其他含义。也就是说，第一拓扑帧是拓扑帧，是第一列车的拓扑帧。
或者，
若第一拓扑帧的初运行标志不为禁止，且第二拓扑帧的初运行标志不为禁止，但第一列车与第二列 车符合禁止编组情况，则确定不满足编组条件。
其中，第一列车与第二列车符合禁止编组情况为：
第一列车和第二列车中的前车弯道减速。或者，
第一列车和第二列车中的前车进入限速路段。或者，
第一列车和第二列车不能同时运行编组规定的时间。
例如，编组规定的时间为10分钟。也就是说，两列车建立灵活编组的前提是辆车可以编组运行10分钟。
如果本列车(即第一列车)拒绝编组(拓扑帧中初运行标志为禁止)或邻车(即第二列车)拒绝编组(拓扑帧中初运行标志为禁止)或两列车不具备编组条件(前车弯道减速、前车进入限速路段、不能同时运行编组规定的时间)则前车保持自动运行(即第一列车位于第二列车前时，第一列车为前车，此时确定自动驾驶)，后车根据前车的运行信息确定灵活编组的运行曲线(即第一列车位于第二列车后时，第一列车为候车，此时，根据第二列车的运行信息确定灵活编组的运行曲线)。
●若根据第二拓扑帧确定满足编组条件，则
2.1当第一列车位于第二列车后时，根据第二列车的运行数据确定灵活编组的运行曲线。
其中，运行数据包括但不限于如下的一种或多种：位置，速度，加速度。
另外，在根据第二列车的运行数据确定灵活编组的运行曲线之后，还会确认通信是否稳定，如果稳定则认为灵活编组建立完成。
确定通信稳定的方式为：连续接收到n个通信周期的报文不丢包，其中，n为预设的正整数，例如，n＝10，即连续10个通信周期报文不丢包。
由于在步骤408中会基于通信，接收第二列车发送的第二拓扑帧，那么，连续接收到n个通信周期的报文不丢包，即连续接收到n个通信周期的第二拓扑帧报文不丢包。如果在步骤408中会基于通信，接收第二列车发送的第二拓扑帧，同时，还接收第二列车发送的第二拓扑帧，那么，连续接收到n个通信周期的报文不丢包，即连续接收到n个通信周期的第二拓扑帧报文不丢包，或者，连续接收到n个通信周期的第二信息帧报文不丢包。
另外，根据列车信息列表与第二列车进行通信之后，还包括：另外，在执行步骤407之后，还会向第二列车发送第一拓扑帧和第一信息帧。
其中，第一信息帧中的“第一”仅为标识作用，为了区分其他列车发送的信息帧，不具备任何其他含义。也就是说，第一信息帧是信息帧，是第一列车的信息帧。
第一列车向第二列车发送第一拓扑帧和第一信息帧的步骤，与步骤408之间的关系可以有多种，例如第一列车先向第二列车发送第一拓扑帧和第一信息帧，再执行步骤408。再例如，第一列车先执行步骤408，再向第二列车发送第一拓扑帧和第一信息帧。还例如，第一列车同时既向第二列车发送第一拓扑帧和第一信息帧，又执行步骤408。
由于一组列车存在两组邻车(即第一列车的前一列车和后一列车)，对于第一列车来说，第二列车是其一组邻车，那么第一列车还会有另一组邻车，为了清楚区分两组不同邻车，将另一组邻车命名为第三 列车。即第三列车为第一列车的邻车，且第三列车与第二列车不同。
其中，第三列车中的“第三”仅为标识作用，为了区分其他列车，不具备任何其他含义。也就是说，第三列车是一组列车，该列车是为第一列车除第二列车之外的另一组邻车。
第一列车在发送第一拓扑帧和接收第二拓扑帧的过程中，还会接收第三列车发送的第三拓扑帧。
其中，第三拓扑帧。中的“第三”仅为标识作用，为了区分其他列车的拓扑帧，不具备任何其他含义。也就是说，第三拓扑帧是一拓扑帧，该拓扑帧是第三列车发送的，即第三列车的拓扑帧。
若第三拓扑帧中不包括第一列车的第一IP地址，则
1、根据第三列车与第一列车的位置关系更新第一列车的第一IP地址列表。
具体的，
●若第三列车位于第一列车前(即第三列车为第一列车的前车)，则
1)获取第二拓扑帧中的第二IP地址列表。
2)将第二IP地址列表放入第一IP地址列表中第一IP地址之后，形成更新的第一IP地址列表。
●若第三列车位于第一列车后(即第三列车为第一列车的后车)，则
1)获取第二拓扑帧中的第二IP地址列表。
2)将第二IP地址列表放入第一IP地址列表中第一IP地址之前，形成更新的第一IP地址列表。
2、根据更新的第一IP地址列表形成新的第一拓扑帧。
也就是说，第一列车和第二列车在互发拓扑帧过程中同时计算新的拓扑帧，如果前车(如第三列车)接收到的拓扑帧中不含有本车(即第一列车)的IP地址则将后车(即第二列车)的拓扑帧IP地址列表放在自己(即第一列车)IP地址后边组成新的IP地址列表形成拓扑帧，如果后车(如第三列车)接收到的拓扑帧不含有本车(即第一列车)的IP地址则将前车(即第二列车)的IP地址列表放在自己(即第一列车)IP地址前面形成新的IP地址列表形成拓扑帧，如果列车接收到的拓扑帧跟本列车的拓扑帧一致则判断初运行成功，设置初运行完成标志后再发送新的拓扑帧，当所有列车接收和发送的拓扑帧的初运行完成标志都一致，则确定灵活编组建立完成，进而编组完成标志，以及，设定列车参考方向。
另外，在根据第二拓扑帧建立灵活编组之后，前车还会获取到后车的控制权。
例如，
●若第一列车位于第二列车前(即第一列车为前车)，则
向第二列车发送控制权获取请求，控制权获取请求用于指示第二列车反馈控制权转移响应。
接收到第二列车反馈的控制权转移响应后，向第二列车发送控制指令，控制指令用于指示第二列车停止自动驾驶。
●若第一列车位于第二列车后(即第一列车为后车)，则
接收第二列车发送控制权获取请求。
向第二列车反馈控制权转移响应。
接收第二列车发送的控制指令。
根据控制指令停止自动驾驶。
例如，如果第一列车为前车，那么第一列车判断编组完成标志为1时，发送控制命令给后车(即第二列车)要求获取控制权，当后车(即第二列车)判断编组完成标志为1且收到前车(即第一列车)的控制命令后发送控制权转移响应给前车(即第一列车)；前车(即第一列车)收到后车(即第二列车)的响应帧后发送具体控制命令给后车(即第二列车)，后车(即第二列车)收到后执行前车(即第一列车)控制命令而不再自动驾驶。
再例如，如果第一列车为后车，那么接收到前车(即第二列车)要求获取控制权后，断编组完成标志为1后发送控制权转移响应给前车(即第二列车)；前车(即第二列车)收到后车(即第一列车)的响应帧后发送具体控制命令给后车(即第一列车)，后车(即第一列车)收到后执行前车(即第二列车)控制命令而不再自动驾驶。
需要说明的是，列车之间(如第一列车与第二列车，第一列车与第三列车等)如果距离在200米以上可采用LTE-R或5G进行通信，如果距离200米以下可以用WIFI或雷达进行通信。
例如，在建立灵活编组时
1)列车在运行过程中实时发送位置信息及列车信息给控制中心；
2)数据交互中心从接收到的列车定位信息中识别出同一轨道上、同向行驶的列车，将列车信息列表发送给相关列车；
3)列车收到列车信息列表后解析列表数据，当列表中的列车数量大于1时且两车之间的距离进入到临界通信距离开始进行车-车通信；
4)前后两列车相互发送信息帧和拓扑帧；
5)如果本列车拒绝编组(拓扑帧中初运行标志为禁止)或临车拒绝编组(拓扑帧中初运行标志为禁止)或两列车不具备编组条件(前车弯道减速、前车进入限速路段、不能同时运行编组规定的时间)则前车保持自动运行，后车根据前车发送给后车的信息计算新的运行曲线；
6)在通信过程中列车时刻判断车间距，在编组完成之前后车根据前车的位置、速度、加速度计算出的新的运行曲线运行；
7)车-车通信稳定判定：列车收到的临车的拓扑帧报文有连续10个报文不丢失就认为通信稳定，列车可以设置通信状态标志为1；
8)列车在互发拓扑帧过程中同时计算新的拓扑帧，如果前车接收到的拓扑帧中不含有本车的IP地址则将后车的拓扑帧IP地址列表放在自己IP地址后边组成新的IP地址列表形成拓扑帧，如果后车接收到的拓扑帧不含有本车的IP地址则将前车的IP地址列表放在自己IP地址前面形成新的IP地址列表形成拓扑帧，如果列车接收到的拓扑帧跟本列车的拓扑帧一致则判断初运行成功，设置初运行完成标志后再发送新的拓扑帧，当所有列车接收和发送的拓扑帧的初运行完成标志都一致，无线编组控制单元就判断编组完成，无线编组控制单元设置编组完成标志，设定列车参考方向；
9)当前车判断编组完成标志为1时，发送控制命令给后车要求获取控制权，当后车判断编组完成标志为1且收到前车的控制命令后发送控制权转移响应给前车；前车收到被控车的响应帧后发送具体控制命令给后车，后车收到后执行前车控制命令而不再自动驾驶。
另外，在建立灵活编组后，会对灵活编组运行进行间隔控制。控制时，前车对灵活编组进行间隔控制体现在：前车会根据后车的牵引力/制动力信息确定各时刻牵引力/制动力，并将确定的牵引力/制动力发送给后车。后车对灵活编组进行间隔控制体现在：向前车发送自身的牵引力/制动力信息，并执行前车确定的牵引力/制动力。如果第一列车位于第二列车前，则第一列车为前车，如果第一列车位于第二列车后，则第一列车为后车。
下面分别针对第一列车位于第二列车前和第一列车位于第二列车后两种情形，分别描述第一列车如何对灵活编组进行间隔控制。
第一种情况：第一列车位于第二列车前，此时第一列车为前车，第二列车为后车。第一列车需要根据后车的牵引力/制动力信息确定各时刻牵引力/制动力，并将确定的牵引力/制动力发送给后车。第二列车需要向第一列车发送自身的牵引力/制动力信息，并执行第一列车确定的牵引力/制动力。
具体的，第一列车会
A.1确定灵活编组的当前运行阶段。
A.2根据当前运行阶段对灵活编组进行间隔控制。
●若当前运行阶段非停车阶段，则
计算下一时刻牵引力/制动力，并根据下一时刻牵引力/制动力进行间隔控制。
●若当前运行阶段为停车阶段，则
当与第二列车之间的距离不小于停车间隔时，基于单车运行曲线减速停车，并计算下一时刻牵引力/制动力，根据下一时刻牵引力/制动力进行间隔控制。
当与第二列车之间的距离小于停车间隔时，在确定满足制动条件后，根据当前速度计算制动距离。每当获取到地面位置信息，则基于制动距离以及获取到的地面位置信息计算当前制动率，根据当前制动力进行减速制动，并计算下一时刻牵引力/制动力，根据下一时刻牵引力/制动力进行间隔控制。
无论当前运行阶段为何种阶段，只要计算下一时刻牵引力/制动力，其计算方法均为：获取第二列车的牵引力/制动力信息，根据牵引力/制动力信息，计算下一时刻牵引力/制动力。
其中，根据牵引力/制动力信息，计算下一时刻牵引力/制动力的过程为：
a.1根据预先得到的速度-间隔距离曲线、与第二列车之间的距离以及当前速度，计算速度偏差。
a.2确定间隔控制最小距离。
具体的，通过如下公式计算间隔控制最小距离：
S min＝T sum*V back+ΔS+d。
其中，
S min为隔控制最小距离。
T sum为延时时间，T sum＝t c+t p+t b，t c为通信中断时间，t p为算法执行时间，t b为制动命令发出到制动施加时间。
V back为第二列车运行速度。
ΔS为第一列车与第二列车紧急制动距离差。
d为安全余量，例如，d为2米。
a.3在满足间隔控制最小距离的前提下，根据速度偏差、列车限速、限加速度、限加加速度值以及牵引力/制动力信息，计算下一时刻牵引力/制动力。
另外，无论当前运行阶段为何种阶段，只要根据下一时刻牵引力/制动力进行间隔控制，其控制过程均为：
通过灵活编组控制单元将下一时刻牵引力/制动力发送给第二列车的灵活编组控制单元。以使第二列车通过灵活编组控制单元将下一时刻牵引力/制动力转发给第二列车的CCU(Central Control Unit，中央控制单元)，通过第二列车的CCU施加下一时刻牵引力/制动力，以便控制第二列车的速度。
第二种情况：第一列车位于第二列车后，此时第二列车为前车，第一列车为后车。第二列车需要根据后车的牵引力/制动力信息确定各时刻牵引力/制动力，并将确定的牵引力/制动力发送给后车。第一列车需要向第二列车发送自身的牵引力/制动力信息，并执行第二列车确定的牵引力/制动力。
具体的，第一列车会向第二列车发送牵引力/制动力信息，以使第二列车根据牵引力/制动力信息，计算下一时刻牵引力/制动力，根据下一时刻牵引力/制动力进行间隔控制。
除此之外，还会通过灵活编组控制单元接收第二列车发送的下一时刻牵引力/制动力。通过灵活编组控制单元将下一时刻牵引力/制动力转发给第二列车的CCU。通过CCU施加下一时刻牵引力/制动力，以便控制第一列车的速度。
通过步骤104对灵活编组进行间隔控制的过程，可以在多列车之间无线编组、自动运行的基础上，实现编组内列车作为一个整体，统一由头车编组运行控制。主要是列车编组后，计算间隔控制曲线，控制列车在灵活编组行进过程中保持行车间隔。
例如，前车根据车辆位置、实时速度、制动距离、制动系统工况等实时状态信号，结合列车制动距离，控制编组内列车行进速度，保持灵活编组列车行车间距，保证列车在特殊工况下能够安全制动，避免追尾。
其中，编组运行的工况如表1所示：
表1
Figure PCTCN2021141522-appb-000001
通过上述过程，实现了第一列车与第二列车进行灵活编组，以及，编组后对灵活编组运行的控制。除了上上述控制过程，还会进行故障预警控制。
进行故障预警控制的前提条件是进行相应传感器信号的采集、信号综合、信号预处理及判断、故障诊断直至故障预警，针对无线灵活编组控制各环节及其相关关系，并在此基础上进行预警。
故障预警控制过程如下：
C.1采集列车运行数据。
本步骤中会采集多种数据，不同的数据可能会触发不同的预警条件，进行不同的预警。
本步骤所采集的列车数据包括：
第一类：单列车网络通信数据
例如：通过网络通信故障预警及诊断分析专家系统的MVB(Multifunction Vehicle Bus，多功能车辆总线)接口采集MVB数据。
通过网络通信故障预警及诊断分析专家系统的TCN(Train Communication Network，列车通信网络)接口采集TCN数据。
通过网络通信故障预警及诊断分析专家系统的ETH(Ethereum，以太坊)接口采集ETH数据。
第二类：单列车走行部在线数据
例如：通过走行部在线监测与故障预警装置采集温度数据和冲击数据。
第三类：单列车塞拉门数据
例如：通过塞拉门故障预警及安全防护系统采集塞拉门行驶多个交路发送的报警信息。
通过塞拉门故障预警及安全防护系统采集停靠轨迹。
第四类：单列车车载设备数据
例如：通过CCU采集车载设备的故障信息以及状态信息。
第五类：编组列车车车通信数据
例如：采集每个通信周期的报文。
第六类：编组列车降级模式数据
例如：采集运行模式和列车速度。
C.2根据列车运行数据进行故障诊断。
对于第一类：单列车网络通信数据，其故障诊断方案为：通过网络通信故障预警及诊断分析专家系统对MVB数据、WTB数据和ETH数据进行实时监控和分析，捕获网络异常。
对于第二类：单列车走行部在线数据，其故障诊断方案为：通过走行部在线监测与故障预警装置对温度数据和冲击数据进行实时监控和分析，检测钢轨典型损伤，并捕获如下一种或多种异常：轴承异常、齿轮传动系统异常、轮对异常。
对于第三类：单列车塞拉门数据，其故障诊断方案为：通过塞拉门故障预警及安全防护系统对获取的报警信息进行筛选，根据筛选后的每个交路的报警信息以及停靠轨迹统计塞拉门的检修信息，根据检修信息的等级分类进行故障诊断。
对于第四类：单列车车载设备数据，其故障诊断方案为：通过CCU对车载设备的故障信息以及状态 信息进行实时监控和分析，捕获设备异常。
对于第五类：编组列车车车通信数据，其故障诊断方案为：根据每个通信周期的报文，确定连续丢包的报文数量，根据连续丢包的报文数量捕获通信异常。
对于第六类：编组列车降级模式数据，其故障诊断方案为：根据运行模式确定是否出现降级模式运行。若出现降级模式运行后，列车速度发生波动，则确定捕获到降级模式异常。
C.3根据故障诊断结果确定检测预警条件是否被触发。
对于第一类：单列车网络通信数据，其是否触发方案为：若通过网络通信故障预警及诊断分析专家系统捕获到网络异常，则确定检测预警条件被触发。
对于第二类：单列车走行部在线数据，其是否触发方案为：若通过走行部在线监测与故障预警装置捕获到任一种异常，或者，检测到钢轨典型损伤，则确定检测预警条件被触发。
对于第三类：单列车塞拉门数据，其是否触发方案为：根据检修信息的等级分类进行故障诊断，故障诊断为出现故障则确定检测预警条件被触发。
对于第四类：单列车车载设备数据，其是否触发方案为：若通过CCU捕获到设备异常，则确定检测预警条件被触发。
对于第五类：编组列车车车通信数据，其是否触发方案为：若连续丢包的报文数量达到m，则确定检测预警条件被触发。
其中，m为预设的正整数，例如，m＝10，即连续10个通信周期的报均出现丢包。
丢包为无法接收到报文和/或收到的报文中拓扑帧与本地拓扑帧不一致。即丢包的情况可以为无法接收到报文，也可以为收到的报文中拓扑帧与本地拓扑帧不一致。
也就是说，连续m个通信周期均会出现无法接收到报文，或者收到的报文中拓扑帧与本地拓扑帧不一致。可以所有通信周期均无法接收到报文，也可以所有通信周期收到的报文中拓扑帧均与本地拓扑帧不一致，还可以部分周期通信周期无法接收到报文，部分周期通信周期收到的报文中拓扑帧与本地拓扑帧不一致。
其中，无法接收到的报文为拓扑帧报文或信息帧报文。
对于第六类：编组列车降级模式数据，其是否触发方案为：若捕获到降级模式异常，则确定检测预警条件被触发。
C.4若预警条件被触发，则进行相应预警。
预警方式可以有多种，如大屏显示，与负责人电话沟通、邮件沟通等。
通过上述故障预警控制过程，可以对多种故障进行预警及救援。
当列车因严重故障无法行驶时，人工驾驶救援列车联挂救援故障列车，使故障列车行驶到下一站，清客下线，然后进入维修区域。
例如：
第一类：单列车网络通信故障
列车装配网络通信故障预警及诊断分析专家系统。该系统内置于一台高性能工业计算机内，该计算机提供MVB、TCN、ETH接口，可以对MVB数据、WTB数据和ETH数据进行实时监控和分析。该 系统设备可以应用于高铁车辆、城际列车、地铁车辆等各种轨道车辆。该系统能够分析符合IEC 61375标准的MVB、WTB、ETH数据，能够提供从物理层信号质量分析到协议分析功能。通过分析信号的波形特征、链路层的帧序列和协议数据，来捕获网络异常，提前发现风险和隐患并将故障信息发送给中央控制单元，保证列车稳定可靠的运行。该系统能够在分析出故障时刻将故障前3分钟和故障后1分钟的该类型数据进行存储，有助于后期分析和整改。
第二类：单列车走行部在线故障
地铁列车走行部在线监测与故障预警装置是为保障地铁列车安全运行而研制的在线实时监测走行部故障状态的预警装置。该装置采用温度监测与冲击监测相结合的多参数诊断机制及故障诊断专家系统，对列车走行部关键部件及典型钢轨损伤进行全面在线监测。
1)实现对可能危害地铁列车安全运行的轴承、齿轮传动系统、轮对(踏面麻点、碾皮、擦伤、烧附、腐蚀、凹痕、裂损、碰伤及轮对多边形等)故障的早期预警及精确定位，为地铁列车的安全运行提供重要保障。同时，通过对运营状态及故障数据进行历史趋势分析、统计分析、对比分析等分析，提供专业化的部件失效根本原因分析及列车维护建议；
2)实现钢轨典型损伤(如钢轨波磨)的检测，为线路的维护提供指导建议。
该监测系统在发现影响列车运行故障时，及时向中央控制单元发送故障信息供中央控制单元做出相关决策。
第三类：单列车塞拉门故障
塞拉门故障预警及安全防护系统通过获取塞拉门行驶多个交路发送的报警信息；对所述报警信息进行筛选；获取列车的速度信息；根据速度信息确定列车的停靠轨迹；根据筛选后的每个交路的报警信息以及停靠轨迹统计塞拉门的检修信息；通过检修信息等级的分类确定出需要及时进行处理的故障上传给中央控制单元，中央控制单元及时作出预警。
第四类：单列车车载设备故障
列车车载设备本身都有自我诊断功能，车载设备在发生故障时及时将故障信息发送给中央控制单元同时记录故障时刻相关通信数据及设备自身状态信息，中央控制单元根据信息等级和车载设备数量根据预先配置的算法执行相关故障预警及安全防护功能。
车地无线传输系统将故障信息及时发送给地面控制中心，地面控制中心专家诊断系统辅助技术人员诊断出列车故障原因，为后期维修和完善专家诊断系统做好工作。
第五类：编组列车车车通信故障
头车连续10次收不到后车报文：头车处理算法保持不变，在发给后车的拓扑帧数据流中设置后车通信中断标志，初运行状态为未完成初运行；
后车连续10次收不到前车报文：头车处理算法保持不变，后车执行解编操作并实行自动运行，后车给头车发送到拓扑帧数据流中设置通信中断标志，初运行状态为未完成初运行；
头车和后车都收不到对方数据达到10个报文：列车将初运行状态设置为初运行未完成状态，列车自动运行，列车保持拓扑帧和信息帧继续发送；
头车和后车通信丢包数量在10个报文以下：记录连续丢包数量，保持原来编组状态运行，连续丢包 不到10个就认为编组运行正常，控制模式不改变；
头车和后车编组状态在建立和解编之间反复：为避免此种工况存在，通信采用冗余技术实现，如果还有则调查是否受外界环境影响，在此处环境下增加辅助通信设备确保消除通信干扰问题，如不能解决，软件层面上则在反复3次后不再进行编组重联，只进行拓扑帧和信息帧收发，初运行状态一直设置为初运行未结束状态，直到连续不丢包时间保持10分钟才设置初运行完成，进行编组运行。
第六类：编组列车降级模式故障
具体包括：
1)编组列车头车降级模式故障
编组运行列车头车因故障出现降级模式运行后如果能继续保持后车最高速度运行则继续编组运行，否则编组运行到最近的避让区间执行解编避让操作(头车过道岔模式)。
2)编组列车后车降级模式故障
编组运行列车后车因故障出现降级模式运行后如果能继续保持后车最高速度运行则继续编组运行，否则编组运行到两车间距达到临界编组距离后头车通信中断后解编各自独立运行。
除此之外，可以对编组列车停车故障进行预警
例如，
针对对编组列车头车停车故障预，编组运行列车头车因故障出现停车故障(包括紧急制动情况)，编组列车不解编，执行编组停车模式。
针对编组列车后车停车故障，编组运行列车后车因故障出现停车故障(包括紧急制动情况)，头车执行解编命令，解编后头车保持自主运行模式，后车上报故障执行停车模式。
还可以对牵引系统故障进行预警。
例如：两车降速模式运行且不解编。
前车处理：列车计算牵引损失程度，修正运行曲线，运行到下一站，清客下线。
列车TCMS(Train Control and Management System，列车控制和管理系统)与TCU(Transmission Control Unit，传动控制单元)通信，通过交互确认故障的TCU数目，计算出列车能够发挥的牵引力、最大运行速度；如果最大速度小于目标速度，则将目标速度设定为最大运行速度，修正运行曲线，运行到下一站，解编，清客下线。
后车处理：解编前按照前车指令编组运行。前车进站道岔前解编，后车恢复自动运行控制。
还可以对制动系统故障进行预警。
例如，两车降速模式运行且不解编。
前车处理：列车计算制动损失程度，修正运行曲线，运行到下一站，清客下线。
后车处理：解编前按照前车指令编组运行。前车进站道岔前解编，后车恢复自动运行控制。
本实施例提供一种灵活编组的解编方法，可以对已经建立灵活编组的列车进行解编。下面再次针对列车编组运行过程，举例介绍本实施例提供的灵灵活编组的解编方法的实现细节。
列车根据地面控制中心提供的可编组列表及列表中各列车的间距进行编组，当列车拓扑目录一致时 表示编组完成，列车设置初运行结束标志；头列车根据编组信息进行协同控制；头车发送解编命令，通过本实施例提供的灵活编组的解编方法进行解编。
编组列车在一条线路上自动运行(没有达到解编、进站、过道岔条件)，编组列车根据到站时间及线路坡度等情况采用自动驾驶算法计算出当前位置到进站前的速度控制曲线，按速度控制曲线合理施加牵引力及制动力以达到节能目的。
编组中前车按照单车自动运行模式驾驶，前车控制后车牵引力制动力施加进行间隔控制。
1、通过步骤101至103建立编组
列车距离大于200m，无线编组控制单元通过获得的每个车位置计算列车间隔。
距离小于200m后通过间隔检测装置获取前后车之间的相对距离。
例如：
1)两车在道岔相遇
具体分为：
(1)不同线路两车在道岔相遇
先获得道岔控制权的列车为前车，优先通过道岔；
前车过道岔前，后车追上前车，建立编组；
前车按单车过道岔模式过道岔；
后车按前车命令运行通过道岔。
(2)同线路两车在道岔相遇
后车追上前车，建立编组，两列车编组按单车过道岔模式过道岔。
2)在两车在道岔相遇之后，后车追前车，此时通过步骤101至103完成两车间的灵活编组建立。
为后车追前车，编组列车达到稳定的目标间隔的行车过程。通过控制列车在运行过程中处于某种间隔采用相应运行速度的方式，达到间隔控制的目标。
编组协同控制根据两车不同工况调整目标间隔。列车变速过程中以加速度和最大减速度运行，同时加速度的变化率(加加速度)不应影响到乘客的舒适性，这些值根据列车的运行特性确定。
根据前后车建立编组时的状态，将工况分为以下9种：
(1)前车匀速运行
前车以速度V1匀速运行，后车以速度V2匀速运行，V2>V1。建立编组时，前车利用车间通信获得后车位置，根据本车位置计算前后车间隔。
前车匀速运行场景分解如表2所示。
表2
序号 编组时刻后车状态 编组后前车控制后车行为
1 匀速 匀速->减速运行
2 加速 加速->减速运行
3 减速 减速到V1->匀速运行
(2)前车匀加速运行
前车以速度V1匀加速运行，后车以速度V2运行，V2>V1。建立编组时，前车利用车间通信获得后车位置，根据本车位置计算前后车间隔。
前车匀加速运行场景分解图表3所示。
表3
Figure PCTCN2021141522-appb-000002
其中，LB1为减速距离，前后车运行达到减速距离后，后车必需减速运行。
(3)前车匀减速运行
前车以速度V1开始匀减速运行，后车以速度V2运行，V2>V1。建立编组时，前车利用车间通信获得后车位置，根据本车位置计算前后车间隔。
前车匀减速运行场景分解如表4所示。
Figure PCTCN2021141522-appb-000003
2、通过步骤104进行间隔控制
建立编组后的第一时刻，后车把自身的牵引力制动力信息发送给前车，前车以后车发挥的牵引力制动力为基础，进行下一时刻力计算。
下一时刻力计算时，根据前车计算出九种工况后车的速度-间隔距离曲线，通过列车间通信获得后车定位信息，计算两列车相对间隔距离；在前车列车稳定接收到后车采用精确定位手段发送的信号后，前车优先使用精确定位手段、冗余使用列车定位计算两车间隔距离的方式获得两车间隔；头车实时采集列车速度信息，根据车间间隔距离，计算速度偏差；根据速度偏差，考虑列车限速、限加速度、限加加速度值，计算需要施加的牵引力/制动力；前车通过无线编组控制单元将需要施加的牵引力/制动力发送给后车无线编组控制单元，后车无线编组控制单元转发给CCU；后车CCU向列车的牵引系统或制动系统发出请求值，以施加牵引力将列车加速到控制速度，或施加制动力使列车减速至规定值。
前车每隔一段时间(5s)计算速度-间隔距离曲线，修正运行偏离。
在间隔控制过中，前后车达到稳定的目标间隔后的行车过程如下：
1)前车加速
前后车由速度V1，加速后稳定运行在速度V2.
间隔距离为S0：前车先施加牵引力，前车根据间隔控制，逐渐对后车施加牵引力。前后车间隔逐渐增大到V2运行下的间隔。
其中，S0为两车平稳运行时两车最小目标间隔距离。建立编组时，后车处于匀速或者加速状态，则 S0为最小目标间隔距离；
2)前车匀速
(1)根据列车载重，前后车同时施加牵引力或制动力。
(2)距离调节模式，调节小段间隔距离。
车间隔由S0，变为S0+d时，后车先减速，后加速，最后与前车稳定运行在速度V1；
车间隔由S0，变为S0-d时，后车先加速，后减速速，最后与前车稳定运行在速度V1。
3)前车减速
前后车由速度V1，减速后稳定运行在速度V2。
1)间隔距离为S0：前车后车先惰行，当前车速度处于最大速度允许误差后，施加制动；后车根据间隔控制，逐渐施加制动力；前后车间隔逐渐减小。
2)间隔距离为S1：前车先施加制动力，后车先保持的在速度V1，逐渐减小间隔；运行到LB1后，减速，逐渐达到目标间隔距离
工况变化后，头车计算工况变化，计算后车的速度-间隔距离曲线，计算需要施加的牵引力/制动力，发送给后车。
其中，S1为前后车目标间隔距离；建立编组时，后车处于减速状态，S1为两列车速度相同时的间隔距离。
4)过道岔模式
(1)编组列车经过道岔后方向相同
编组过道岔与单车过道岔行为没有区别，相当于单列车的车身变长，经过道岔的时间变长。
(2)编组列车经过道岔后方向不同
通过本实施例提供的灵活编组的解编方法，编组进入解编模式。
5)两车编组过道岔后不解编
编组列车按单车过道岔模式通过道岔。
6)两车编组过道岔后解编
两车目的地不同时，在线路不同的道岔前，通过本实施例提供的灵活编组的解编方法进行解编。两种工况均为道岔动作到不同方向。
此时，前车在道岔动作距离L2与道岔建立通信，道岔受控，前车控制道岔动作；道岔最迟在道岔状态反馈距离L3反馈状态，道岔状态正常后，通过本实施例提供的灵活编组的解编方法进行解编，前车经过道岔；道岔状态反馈故障，前车以道岔减速度减速，编组不解编。
后车在道岔动作距离L2开始以道岔减速度运行。
通过本实施例提供的灵活编组的解编方法解编后，后车尝试与道岔通信，获得控制权后，控制道岔向不同方向动作；
过道岔后按照电子地图计算运行曲线。
其中，L2＝道岔动作时间内列车行驶的最大距离+道岔减速时间内列车行驶的最大距离。
L3为道岔减速时间内列车行驶的最大距离
前车按单车过道岔模式过道岔，后车按前车命令逐渐增加运行间隔后，通过本实施例提供的灵活编组的解编方法进行解编。解编后后车根据当前状况确定自动运行控制模式(在道岔前没有获得道岔控制就按照道岔减速度减速，直至停车)。
3、停车过程
停车过程中，前车后车速度由V1逐渐减小到0，由运行时的间隔S减少到停车间隔St。
其中，St为设置的前后车目标停车间隔距离。S为前后车实际间隔距离。
可靠的控制停车的距离差需要在0.3m。
S>＝St时，前车按照单车运行曲线减速停车，后车根据间隔控制，缩小与前车间隔，间隔达到St后，前车控制后车保持间隔距离为St运行，不再按照最小间隔进一步缩小行车间隔。
S<St时，在前车匀速运行阶段，控制后车减速，调整前后车间隔由S变为St；前车按照单车运行曲线减速停车，前车控制后车保持间隔距离为St，不再按照最小间隔进一步缩小行车间隔。
停车过程中，无线两编组的前车后车速度由V1逐渐减小到0，由运行时的间隔S减少到停车间隔St。
前车按照单车运行曲线减速，以常用制动减速停车；后车根据间隔控制曲线，减速度小于前车减速度，逐渐缩小与前车间隔。
前车停车过程：列车以一定速度驶入站内,该速度为制动前初始速度(例如车速已降至9-11.5m/s)，进站后列车开始制动，从列车开始制动到列车完全停稳的距离称为制动距离，在该距离内按一定分布(布置信标进行列车定位)，列车每经过信标时，获取该处的地面位置信息，通过速度-距离运算模块进行算法运算得到当前位置上最为适合的理论制动率，该理论制动率便作为实际制动率控制列车进行减速制动。当列车到达下一个定位位置时，执行与上述相同的过程，直到列车速度为零，即停稳在停车点。
后车停车过程：后车由运行时的间隔S运行到停车间隔St，前车制动进站时，实时检测前后车间隔；前车根据速度-间隔曲线，计算后车施加的牵引力制动力。
