The invention provides a gap measuring unit of a maglev train. The gap measuring unit comprises m1 sub-gap measuring units are arranged at m1 positions in the rail direction respectively, m1 is largerthan or equal to 2, each sub-gap measuring unit comprises a first induction coil, at least m2 sub-gap measuring units in the m1 sub-gap measuring units comprise second induction coils, m2 is larger than or equal to 1 and smaller than or equal to m1, m1 + m2 is larger than or equal to 4, the first induction coils and the second induction coils are located at different height positions in the height direction of the maglev train, in the same sub-gap measuring unit, the length of a first projection is greater than the length of a second projection, the second projection is in the first projection, and endpoints of the first projection and the second projection do not coincide with each other. The gap measuring unit is advantaged in that two gap measuring probes with different sizes are superposed at the same position, so the information of the maglev train passing through a rail gap can be effectively identified.

    本发明提供一种磁浮列车的间隙测量单元,包括分别设置于沿轨道方向的m1个位置上的m1个子间隙测量单元,m1≥2,每个子间隙测量单元均包括第一感应线圈,m1个子间隙测量单元中,至少有m2个子间隙测量单元均包括第二感应线圈,1≤m2≤m1,m1+m2≥4;第一感应线圈、第二感应线圈在磁浮车辆高度方向上位于不同的高度位置;在同一个子间隙测量单元中,第一投影的长度大于第二投影的长度,第二投影在第一投影内,且第一投影、第二投影的端点互不重合。本发明中,采用两种不同尺寸的间隙测量探头叠加在同一位置,能有效识别车辆过轨缝信息。
