本申请涉及轨道车辆技术领域，特别是涉及一种悬浮间隙测量方法、装置、设备及介质。
背景技术
高速磁浮列车悬浮间隙测量是确保列车稳定运行的关键技术之一。悬浮间隙是指列车与轨道之间的距离，通常在10mm左右。为了实现准确的悬浮间隙测量，需要使用专门的传感器。
目前，由于长定子齿槽结构的影响，悬浮传感器在测量间隙时会产生纹波干扰，对悬浮系统的稳定性产生不利影响。为了降低这种齿槽纹波的影响，当前传感器设计采用了三维线圈形状和尺寸优化的措施，但这也导致了对线圈粘接和浇注工艺的要求提高，使得传感器成品率较低，生产成本较高，限制了悬浮系统的性能和可靠性，同时也增加了列车的整体成本。
鉴于上述问题，如何解决高速磁浮列车悬浮间隙测量过程中存在间隙纹波，是该领域技术人员亟待解决的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部实施例。基于本申请中的实施例，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，都属于本申请保护范围。
本申请的核心是提供一种悬浮间隙测量方法、装置、设备及介质，以解决高速磁浮列车悬浮间隙测量过程中存在间隙纹波的问题。
为了使本技术领域的人员更好地理解本申请方案，下面结合附图和具体实施方式对本申请作进一步的详细说明。
为了解决高速磁浮列车悬浮间隙测量过程中存在间隙纹波的问题，本申请提供了一种悬浮间隙测量方法。
需要说明的是，本申请提供的方法应用于包括第一探头组、第二探头组、后端处理电路和控制器的测距系统。其中，第一探头组和第二探头组的检测原理为电感式测距，探头组具体由多个线圈探头构成，随着电磁铁与长定子之间的间隙波动，探头检测电感变化。其次，第一探头组和第二探头组分别与对应的后端处理电路连接，各后端处理电路与控制器连接；后端处理电路获取第一探头组和第二探头组传输的电感值变化，得到对应的间隙值，并根据与控制器之间的协议，将检测到的间隙值发送至控制器。
图1为本申请实施例提供的探头组安装位置的示意图。如图1所示，在本申请中第一探头组7设置于长定子5槽结构对向的电磁铁6表面，第二探头组8设置于与长定子5槽结构相邻的齿结构对向的电磁铁6表面。需要在注意的是，本实施例中对于第一探头组和第二探头组的具体构造不做限制，根据具体的实施情况而定。
图2为本申请实施例提供的一种悬浮间隙测量方法的流程图。如图2所示，方法包括：
S10：获取第一探头组测量的第一间隙值和第二探头组测量的第二间隙值，并选取实际间隙值的确定方式。
S11：当选取第一确定方式时，确定第一间隙值和第二间隙值的平均值，以将平均值确定为实际间隙值。
S12：当选取第二确定方式时，确定第一间隙值和第二间隙值二者中的最小值，并获取第一间隙补偿值。
S13：将最小值与第一间隙补偿值加和，以得到实际间隙值。
在具体实施中，首先获取第一探头组测量的第一间隙值和第二探头组测量的第二间隙值。可以理解的是，由于第一探头组和第二探头组所设置的位置不同，因此二者测量出的间隙值不能直接作为实际间隙值。为了得到长定子与电磁铁之间实际的间隙值，需要选取实际间隙值的确定方式。
需要说明的是，本实施例中共提供两种实际间隙值的确定方式，这两种方式均能够消除实际间隙值测量过程中的纹波干扰。
具体地，当选取第一确定方式时，确定第一间隙值和第二间隙值的平均值，以将平均值确定为实际间隙值。而当选取第二确定方式时，确定第一间隙值和第二间隙值二者中的最小值，并获取第一间隙补偿值；将最小值与第一间隙补偿值加和，以得到实际间隙值。需要注意的是，本实施例中对于第一间隙补偿值的具体大小不做限制，根据具体的实施情况而定。
此外，还存在一种消除纹波的可行方式：通过构建间隙纹波处理模型，设置模型输入为第一探头组测量的间隙值、第二探头组测量的间隙值以及长定子与电磁铁之间的标准间隙，设置模型输出为实际间隙值；以规定纹波为约束条件/目标值，通过地面试验获取样本数据，采用机器学习算法(例如极端梯度提升算法、随机森林算法、贝叶斯统计等)对模型进行训练，获取最终的间隙纹波处理模型，并应用于测距系统。
本实施例中，根据长定子的齿槽结构引起的间隙波动对传感器探头进行合理布局，设置第一探头组和第二探头组形成传感器阵列。通过多探头组配合，结合间隙值取平均和间隙值补偿这两种实际间隙值的测量方式，能够有效减小甚至消除悬浮间隙测量中存在的纹波，提升悬浮控制系统的稳定性。
图3为本申请实施例提供的一种探头安装方式的示意图。在上述实施例的基础上，在一些实施例中，如图3所示，第一探头组和第二探头组分别由沿电磁铁延伸方向平行排列的三个探头组成。
对应地，在上述第一探头组的探头安装方式下，获取第一探头组测量的第一间隙值，包括：
S101：获取第一探头组中各探头测量的间隙值；
S102：判断各间隙值中是否存在与其余间隙值的差值均大于第一阈值的第一目标间隙值；若否，则进入步骤S103；若是，则进入步骤S104。
S103：确定第一探头组中各间隙值的平均值，以将各间隙值的平均值作为第一间隙值。
S104：确认第一目标间隙值对应的探头为第一故障探头。
S105：标记第一故障探头，并生成表征第一故障探头故障的告警信息。
S106：获取第一探头组中第一故障探头以外其余探头测量的间隙值的平均值，以将第一探头组中其余间隙值的平均值作为第一间隙值。
为获取第一间隙值，首先获取第一探头组中各探头测量的间隙值，也就是获取三个探头测量的间隙值。进一步判断各间隙值中是否存在与其余间隙值的差值均大于第一阈值的第一目标间隙值。本实施例中对于第一阈值大小不做限制，根据具体的实施情况而定。
若不存在与其余间隙值的差值均大于第一阈值的第一目标间隙值，则认为三个间隙值的偏差在允许的范围内，则确定第一探头组中各间隙值的平均值，以将三个间隙值的平均值作为第一间隙值。
若存在与其余间隙值的差值均大于第一阈值的第一目标间隙值，则认为三路探头中其中一路探头测得的第一目标间隙值与其他两路探头测得的间隙值相比明显偏差较大，确认第一目标间隙值对应的探头为第一故障探头。此时，标记第一故障探头，并生成表征第一故障探头故障的告警信息，以便于工作人员根据标记和告警信息对第一故障探头进行维护。获取第一探头组中第一故障探头以外其余探头测量的间隙值的平均值，也就是获取剩余的两路探头的间隙值的平均值，以将第一探头组中其余间隙值的平均值作为第一间隙值，从而提高第一间隙值测量的准确性。
对应地，在上述第二探头组的探头安装方式下，获取第二探头组测量的第二间隙值，包括：
S107：获取第二探头组中各探头测量的间隙值。
S108：判断各间隙值中是否存在与其余间隙值的差值均大于第一阈值的第二目标间隙值；若否，则进入步骤S109；若是，则进入步骤S110。
S109：确定第二探头组中各间隙值的平均值，以将各间隙值的平均值作为第二间隙值；
S110：确认第二目标间隙值对应的探头为第二故障探头。
S111：标记第二故障探头，并生成表征第二故障探头故障的告警信息。
S112：获取第二探头组中第二故障探头以外其余探头测量的间隙值的平均值，以将第二探头组中其余间隙值的平均值作为第二间隙值。
为获取第二间隙值，首先获取第二探头组中各探头测量的间隙值，也就是获取三个探头测量的间隙值。进一步判断各间隙值中是否存在与其余间隙值的差值均大于第一阈值的第二目标间隙值。本实施例中对于第一阈值大小不做限制，根据具体的实施情况而定。
若不存在与其余间隙值的差值均大于第一阈值的第二目标间隙值，则认为三个间隙值的偏差在允许的范围内，则确定第二探头组中各间隙值的平均值，以将三个间隙值的平均值作为第二间隙值。
若存在与其余间隙值的差值均大于第一阈值的第二目标间隙值，则认为三路探头中其中一路探头测得的第二目标间隙值与其他两路探头测得的间隙值相比明显偏差较大，确认第二目标间隙值对应的探头为第二故障探头。此时，标记第二故障探头，并生成表征第二故障探头故障的告警信息，以便于工作人员根据标记和告警信息对第二故障探头进行维护。获取第二探头组中第二故障探头以外其余探头测量的间隙值的平均值，也就是获取剩余的两路探头的间隙值的平均值，以将第二探头组中其余间隙值的平均值作为第二间隙值，从而提高第二间隙值测量的准确性。
图4为本申请实施例提供的另一种探头安装方式的示意图。在上述实施例的基础上，在一些实施例中，如图4所示，第一探头组和第二探头组分别由沿电磁铁延伸方向平行排列的两个探头组成。
对应地，在上述第一探头组的探头安装方式下，获取第一探头组测量的第一间隙值，包括：
S111：获取第一探头组中两个探头测量的间隙值。
S112：确定第一探头组中两个间隙值的平均值，以将两个间隙值的平均值作为第一间隙值。
为获取第一间隙值，首先获取第一探头组中两个探头测量的间隙值，进一步确定第一探头组中两个间隙值的平均值，以将两个间隙值的平均值作为第一间隙值。
对应地，在上述第二探头组的探头安装方式下，获取第二探头组测量的第二间隙值，包括：
S113：获取第二探头组中两个探头测量的间隙值。
S114：确定第二探头组中两个间隙值的平均值，以将两个间隙值的平均值作为第二间隙值。
为获取第二间隙值，首先获取第二探头组中两个探头测量的间隙值，进一步确定第二探头组中两个间隙值的平均值，以将两个间隙值的平均值作为第二间隙值。
在上述实施例的基础上，在一些实施例中，在获取第一探头组中两个探头测量的间隙值之后，还包括：
S121：判断两个间隙值的差值是否大于第二阈值；若不大于第二阈值，则进入步骤S112；若大于第二阈值，则进入步骤S122。
S122：将第一探头组中两个间隙值中最大的间隙值确定为第三目标间隙值。
S123：将第一探头组中两个间隙值中最小的间隙值确定为第四目标间隙值。
S124：获取第二探头组中两个探头测量的间隙值。
S125：根据第二探头组中两个探头测量的间隙值，分别判断第三目标间隙值和第四目标间隙值是否在第一预设范围内；若第三目标间隙值在第一预设范围内，则进入步骤S126。若第四目标间隙值在第一预设范围内，则进入步骤S129。
S126：确认第四目标间隙值对应的探头发生故障。
S127：标记第四目标间隙值对应的探头，并生成表征第四目标间隙值对应的探头发生故障的告警信息。
S128：将第三目标间隙值作为第一间隙值。
S129：确认第三目标间隙值对应的探头发生故障。
S130：标记第三目标间隙值对应的探头，并生成表征第三目标间隙值对应的探头发生故障的告警信息。
S131：将第四目标间隙值作为第一间隙值。
在具体实施中，当第一探头组采用两个探头时，完全依赖两个探头的间隙值的平均值作为第一间隙值。一旦其中一个探头出现故障，对应间隙值产生较大偏差，就会导致第一间隙值的测量不准确。因此为了避免出现上述情况，在获取第一探头组中两个探头测量的间隙值之后，还需要判断两个间隙值的差值是否大于第二阈值。本实施例中对于第二阈值大小不做限制，根据具体的实施情况而定。
若不大于第二阈值，则确认两个探头测得的间隙值的偏差在允许范围内，进入确定第一探头组中两个间隙值的平均值，以将两个间隙值的平均值作为第一间隙值的步骤。若大于第二阈值，则确认两个探头测得的间隙值的偏差超限，会导致第一间隙值的测量不准确。
为了避免第一间隙值的测量不准确，具体将第一探头组中两个间隙值中最大的间隙值确定为第三目标间隙值；将第一探头组中两个间隙值中最小的间隙值确定为第四目标间隙值。获取第二探头组中两个探头测量的间隙值。将第二探头组测得间隙值作为比对对象，根据第二探头组中两个探头测量的间隙值，分别判断第三目标间隙值和第四目标间隙值是否在第一预设范围内。本实施例中对于第一预设范围不做限制，需要依据第二探头组中两个探头测量的间隙值确定该第一预设范围；在第一预设范围内的间隙值被认为是正常的间隙值。
若第三目标间隙值在第一预设范围内，则认为第三目标间隙值相对来说是一个正常的测量值，第四目标间隙值相对来说是一个异常的测量值，可将第三目标间隙值作为第一间隙值。此时确认第四目标间隙值对应的探头发生故障；进一步标记第四目标间隙值对应的探头，并生成表征第四目标间隙值对应的探头发生故障的告警信息，以便于工作人员根据标记和告警信息对第四目标间隙值对应的探头进行维护。若第四目标间隙值在第一预设范围内，则认为第四目标间隙值相对来说是一个正常的测量值，第三目标间隙值相对来说是一个异常的测量值，可将第四目标间隙值作为第一间隙值。此时确认第三目标间隙值对应的探头发生故障；进一步标记第三目标间隙值对应的探头，并生成表征第三目标间隙值对应的探头发生故障的告警信息，以便于工作人员根据标记和告警信息对第三目标间隙值对应的探头进行维护。以此，保证了第一间隙值的准确测量。
此外，本实施例中主要对于在第一探头组采用两个探头情况下的第一间隙值的准确测量进行了说明。可以理解的是，本实施例中所采用的方式同样适用于在第二探头组采用两个探头情况下的第二间隙值测量，从而保证第二间隙值测量的准确性。只是需要注意的是，区别于本实施例中以第二探头组作为比对对象，当进行第二探头组下的第二间隙值测量时，需要以第一探头组测得间隙值作为比对对象，具体过程在本实施例中不再赘述。
在上述实施例的基础上，在获取第一探头组测量的第一间隙值和第二探头组测量的第二间隙值之后，在选取实际间隙值的确定方式之前，还包括：
S132：获取第二间隙补偿值。
S133：判断第一间隙值与第二间隙值的差值是否大于第三阈值；若第一间隙值与第二间隙值的差值大于第三阈值，则进入步骤S134；若第一间隙值与第二间隙值的差值不大于第三阈值，则进入步骤S135。
S134：将第二间隙值与第二间隙补偿值加和，以得到新的第一间隙值，进入选取实际间隙值的确定方式的步骤；
S135：判断第二间隙值与第一间隙值的差值是否大于第三阈值；若第二间隙值与第一间隙值的差值大于第三阈值，则进入步骤S136；若第二间隙值与第一间隙值的差值不大于第三阈值，则进入选取实际间隙值的确定方式的步骤。
S136：将第一间隙值与第二间隙补偿值加和，以得到新的第二间隙值，进入选取实际间隙值的确定方式的步骤。
在具体实施中，当悬浮列车通过梁端接缝时，第一间隙值和第二间隙值会远远大于实际间隙值，导致实际间隙值测量失败。因此为了保证实际间隙值的准确测量，具体获取第二间隙补偿值。本实施例中对于第二间隙补偿值不做限制，根据具体的实施情况而定。
进一步判断第一间隙值与第二间隙值的差值是否大于第三阈值；若第一间隙值与第二间隙值的差值大于第三阈值，则认为此时第一间隙值为在接缝处测量的错误值。为了避免错误的第一间隙值导致实际间隙值的测量失败，具体将第二间隙值与第二间隙补偿值加和，以得到新的第一间隙值，进入选取实际间隙值的确定方式的步骤，进行后续的实际间隙值的计算。
若第一间隙值与第二间隙值的差值不大于第三阈值，则认为此时第一间隙值为正确值，进一步判断第二间隙值与第一间隙值的差值是否大于第三阈值；若第二间隙值与第一间隙值的差值大于第三阈值，则认为此时第二间隙值为在接缝处测量的错误值。为了避免错误的第二间隙值导致实际间隙值的测量失败，具体将第一间隙值与第二间隙补偿值加和，以得到新的第二间隙值，进入选取实际间隙值的确定方式的步骤，进行后续的实际间隙值的计算。若第二间隙值与第一间隙值的差值不大于第三阈值，则认为第一间隙值和第二间隙值均为正确值，进入选取实际间隙值的确定方式的步骤。
以此，保证了列车通过梁端接缝时不影响实际间隙值的测量。
在上述实施例的基础上，在一些实施例中，还包括：
S14：根据预设周期监测实际间隙值，并监测列车的当前速度；
S15：判断实际间隙值是否超出第二预设范围，且列车的当前速度大于速度阈值；若是，则进入步骤S16。
S16：输出告警信息。
在具体实施中，还可根据预设周期持续监测测量得到的实际间隙值，同时监测列车的当前速度。进一步判断实际间隙值是否超出第二预设范围，且列车的当前速度大于速度阈值；本实施例中对于第二预设范围和速度阈值均不做限制，根据具体的实施情况而定。
若实际间隙值未超出第二预设范围和/或列车的当前速度不大于速度阈值，则继续进行监测。若实际间隙值超出第二预设范围，且列车的当前速度大于速度阈值，则认为在列车的当前速度下间隙异常，继续运行可能会存在安全风险，需要输出告警信息以提示工作人员对列车进行减速并进行检查。
此外，为了提高工作人员的检查效率，当实际间隙值超出第二预设范围，且列车的当前速度大于速度阈值时，还包括：
S17：记录当前第一探头组和第二探头组相对于长定子的距离。
S18：生成测量日志；其中，测量日志包含在实际间隙值超出第二预设范围之前预设时间段内的实际间隙值的变化情况。
具体地，为了提高工作人员的检查效率，还需要记录当前第一探头组和第二探头组相对于长定子的距离，以便于工作人员查看异常间隙值。同时生成测量日志；测量日志包含在实际间隙值超出第二预设范围之前预设时间段内的实际间隙值的变化情况，以便于工作人员根据测量日志对间隙变化情况进行排查。
