具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。
请参考图1至图5，图1为具体实施例中待测悬浮传感器的结构示意图；图2为本发明所提供检测系统的检测部件安装于待测悬浮传感器的结构示意图；图3为本发明所提供检测系统一种具体实施例的原理框图；图4为具体实施例中检测系统的第一测试线圈单元的布局示意图；图5为具体实施例中检测系统的第二测试线圈单元的布局示意图。
该实施例提供的检测系统用于磁浮列车悬浮系统，磁浮列车的悬浮系统包括悬浮传感器01、悬浮控制器02和电磁铁(图中未示出)，其中，悬浮传感器01安装在电磁铁上，悬浮控制器02与悬浮传感器01和电磁铁连接，能够获取悬浮传感器01和电磁铁的相关参数信息。
该实施例的检测系统包括控制器10和检测部件20，控制器10与悬浮控制器02和检测部件20通信连接。
检测部件20包括驱动单元21、第一测试线圈单元22和第二测试线圈单元23。
其中，第一测试线圈单元22的第一测试线圈组221与待测的悬浮传感器01的间隙线圈的数目、位置和尺寸均对应，也就是说，待测的悬浮传感器01具有几个间隙线圈，第一测试线圈单元22就设有几个第一测试线圈组221，且，每个第一测试线圈组221与待测的悬浮传感器01的对应间隙线圈的位置在空间上对应，尺寸也对应，每个第一测试线圈组221设有至少一个线圈。第一测试线圈单元22用于模拟悬浮传感器01的外部磁场状态，通过对各第一测试线圈组221的线圈的控制，可以模拟出不同的间隙值，可以理解，为更好地对悬浮系统进行检测第一测试线圈单元22的设置应当能够满足悬浮传感器01的间隙通道的全量程的间隙变化值，在一个实 例中，该间隙变化值的范围为0mm～20mm。
就目前的应用来说，悬浮传感器01通常具有两个间隙线圈，行业内称之为A通道间隙线圈和B通道间隙线圈，所以图示方案中的第一测试线圈单元22也设有两个第一测试线圈组221，分别与A通道间隙线圈和B通道间隙线圈对应。可以理解，在实际应用中，若待测的悬浮传感器01的间隙线圈发生变化，检测部件20的第一测试线圈单元22的第一测试线圈组221对应设置，不再一一举例说明。
其中，第二测试线圈单元23的第二测试线圈组231与待测的悬浮传感器01的速度线圈的数目、位置和尺寸均对应，也就是说，待测的悬浮传感器01具有几个速度线圈，第二测试线圈单元23就设有几个第二测试线圈组231，且，每个第二测试线圈组231与待测的悬浮传感器01的对应速度线圈的位置在空间上对应，尺寸也对应，每个第二测试线圈组231设有至少一个线圈。第二测试线圈单元23用于模拟电感变化，使得待测的悬浮传感器01内的速度线圈能够等效识别出长定子齿槽结构的水平运行，以实现速度测量，也就是说通过对第二测试线圈单元23的各第二测试线圈组231的线圈的控制，可以模拟出所需要测试的速度值，那么，在具体设置时，第二测试线圈单元23的具体设置与需要测试的速度范围相关，在一个实例中，模拟的速度范围为0～600Km/h。
就目前的应用来说，悬浮传感器01通常也具有两个速度线圈，所以图示方案中的第二测试线圈单元23也相应设有两个第二测试线圈组231，分别与两个速度线圈对应。可以理解，在实际应用中，若待测的悬浮传感器01的速度线圈发生变化，检测部件20的第二测试线圈单元23的第二测试线圈组231也对应设置，不再一一举例说明。
第一测试线圈组221和第二测试线圈组231均包括至少一个线圈。
检测部件20的驱动单元21用于根据控制器10的控制指令发送驱动信号至第一测试线圈单元22和/或第二测试线圈单元23，也就说说，通过驱动单元21对第一测试线圈单元22的各第一测试线圈组221的线圈进行控制，以模拟不同的间隙值，通过驱动单元21对第二测试单元23的各第二测试线圈组231的线圈进行控制，以模拟不同的速度值。
显然，驱动单元21与第一测试线圈单元22和第二测试线圈单元23 均通信连接。
控制器10还用于采集悬浮控制器02反馈的参数信息。
如上，该检测系统可以将检测部件20安装在待测的悬浮传感器01上，使检测部件20的第一测试线圈单元22和第二测试线圈单元23分别与悬浮传感器01的间隙线圈和速度线圈对应，通过控制器10发送控制指令至驱动单元21，驱动单元21根据接收的控制指令生成驱动信号，并发送至第一测试线圈单元22和第二测试线圈单元23，以模拟列车运行时不同的间隙值和速度值，悬浮控制器02通过接收悬浮传感器01采集的间隙信号和速度信号进行处理，从而调节电磁铁的驱动电流，在此过程中，控制器10采集悬浮控制器02反馈的参数信息，实现对悬浮系统的测试，并以此进行悬浮系统的调试，另外，通过对第一测试线圈单元22和第二测试线圈单元23的控制也可以实现故障模拟，还可以根据测试进行现车故障排查，规避了现有技术中搭建试验台所需要的成本，在现车上即可进行，提高了检测效率，同时，该检测系统的设备体积小，便于携带。
具体应用中，根据待测的悬浮传感器01的数目，可以设置匹配的多个检测部件20，这些检测部件20可以同一个控制器10通信，控制器10对不同的检测部件20发送不同的控制指令，以满足不同的测试需求。
具体的方案中，第一测试线圈单元22的第一测试线圈组221设置有两个以上的线圈，各线圈相对独立，即驱动单元21可以控制第一测试线圈组221的不同线圈的通断，彼此不受影响。
如图4所示，每个第一测试线圈组221设有多个线圈，第一测试线圈组221的宽度X3和长度Y2与对应的悬浮传感器01的间隙线圈一致，两个第一测试线圈组221之间的间隔距离与悬浮传感器01中两个间隙线圈的间隔距离一致。
第二测试线圈单元23的第二测试线圈组231设置有两个以上的线圈，各线圈也相对独立，即驱动单元21可以控制第二测试线圈组231的不同线圈的通断，彼此不受影响。
如图5所示，每个第二测试线圈组231设有多个线圈，第二测试线圈组231的宽度X1和长度Y与对应的悬浮传感器01的速度线圈一致，两个第二测试线圈组231之间的间隔距离与悬浮传感器01中两个速度线圈的间 隔距离一致。
在上述设置的基础上，驱动单元21对于测试线圈组的驱动信号包括各测试线圈组的每个线圈的通断状态、通断频率，这些线圈的通断顺序以及线圈通断的数目，具体以实际测试时对应工况所需要求为准。
具体的方案中，悬浮控制器02反馈的参数信息包括悬浮传感器的间隙值、速度值以及对应电磁铁的电流值。
具体设置时，第一测试线圈单元22和第二测试线圈单元23可以设置在一个电路板上，且第一测试线圈单元22和第二测试线圈单元23在电路板内处于不同的平面，以免两者相互干扰。当然，驱动单元21可以为驱动控制电路，也设置在同一电路板上，或者单独设置。
具体的，驱动单元21可以通过控制电路驱动逻辑开关器件或者继电器生成驱动信号。
当然，可以理解，也可以将第一测试线圈单元22设置在一个电路板上，第二测试线圈单元23设置在另一个电路板上。
如图1所示，通常的悬浮传感器01具有检测面，整体呈L形结构，实际设置时，检测部件20设有外壳24，该外壳24的外形与悬浮传感器01一致，以方便将外壳24安装在悬浮传感器01上，前述驱动单元21、第一测试线圈单元22和第二测试线圈单元23均安装在外壳24内，如此，将检测部件20的各部件集成在外壳24内，方便安装。
参考图2，外壳24包括与悬浮传感器01的检测面011对应的壳体部241，安装后，该壳体部241置于悬浮传感器01的检测面011上，第一测试线圈单元22和第二测试线圈单元23均安装在壳体部241内，具体地，第一测试线圈单元22的各第一测试线圈组221的各线圈的长度方向与壳体部241的宽度方向一致，即与悬浮传感器01的检测面011的宽度一致，第二测试线圈单元23的各第二测试线圈组231的各线圈的长度方向与壳体部241的长度方向一致，即与悬浮传感器01的检测面的长度一致，如前所述，这与悬浮传感器01内的间隙线圈和速度线圈的排布方向相关。
为方便安装和检测，检测部件20还在外壳24内设有无线通信模块25，驱动单元21具体通过无线通信模块25实现与控制器10的通信。
为实现检测部件20的供电及设备续航，检测部件20的外壳24内还设 有电源模块，该电源模块具体可以为电池26，当然也可以为已有的其他电源形式。
实际应用时，根据需要测试的悬浮传感器01的数量，准备检测部件20，将检测部件20放置于待测的悬浮传感器01上，调试人员可通过控制器10向检测部件20的驱动单元21发送控制指令，以生成驱动信号，可以设置模拟全间隙范围、全速度范围，测试不同间隙、不同速度下悬浮控制器02反馈的间隙值、速度值和电流值等参数；同时，也可以设置某一个或多个悬浮传感器01的速度异常(过快或过慢)或间隙异常(过大或过小)，来监测悬浮控制器02的响应能力或逻辑处理方式等，判断悬浮控制器02的工作状态，实现悬浮系统的闭环检测。
以上对本发明所提供的用于磁浮列车悬浮系统的检测系统进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
