The invention provides a high-speed maglev train speed measurement sensor and a maglev train, and relates to the technical field of maglev train speed measurement. The high-speed maglev train speed measurement sensor comprises a sensor body capable of being installed on a maglev train, at least one probe coil installed on the sensor body and parallel to a long stator of a maglev track, and a sampling processing circuit. The probe coil is in a planar spiral shape and is loaded with an alternating excitation signal; the sampling processing circuit can process the alternating current signal of the probe coil into a digital signal indicating the impedance change of the probe coil. The high-speed maglev train speed measurement sensor provided by the invention can perform high-precision real-time speed measurement on a maglev train, and is low in cost.

    本发明提出了一种高速磁悬浮列车测速传感器及磁悬浮列车,涉及磁悬浮列车测速技术领域,该高速磁悬浮列车测速传感器包括:可安装于磁悬浮列车上的传感器本体、至少一个安装于传感器本体上且与磁悬浮轨道长定子平行设置的探头线圈、采样处理电路;所述探头线圈为平面螺旋状,且加载有交变的激励信号;所述采样处理电路可将探头线圈的交流信号处理成指示探头线圈阻抗变化的数字信号。本发明提出的高速磁悬浮列车测速传感器可对磁悬浮列车进行高精度的实时测速,同时成本较低。
