本发明系揭露一种列车速度量测设备及其方法。该列车速度量测设备包含：至少一第一转速计设置在一拖曳车的一轴上且根据该拖曳车之一车轮转速输出一脉波信号；至少一第二转速计设置在一电动车的一轴上且根据该电动车之一车轮转速输出一脉波信号；至少一速度量测单元用以量测根据从该至少一第一转速计和该至少一第二转速计所输出的该些脉波信号的速度值；一速度计算单元用以根据所量测的该些速度值来计算该列车的速度。

Provided are a train speed measuring device and method. The train speed measuring device includes: at least one first tachometer disposed at an axle of a trailer car and for outputting a pulse signal according to a wheel revolution of the trailer car; at least one second tachometer disposed at an axle of a motor car and for outputting a pulse signal according to a wheel revolution of the motor car; at least one speed measuring unit for measuring speed values on the basis of pulse signals outputted from the at least one first tachometer and the at least one second tachometer; and a speed calculating unit for calculating the speed of the train on the basis of the measured speed values.
