The invention discloses a railway vehicle and a speed measurement and positioning system thereof, belongs to the field of railway vehicles, and is used for speed measurement and positioning of the railway vehicle. According to the application, the alternating magnetic field generating device is arranged on the target rail vehicle, so that the oscillation devices arranged on the optical fiber at intervals can generate resonance under the induction of the alternating magnetic field generated by the alternating magnetic field generating device and reflect the optical signal transmitted in the optical fiber along with the operation of the target rail vehicle; the optical signal processing module can calculate the current speed of the target rail vehicle and the position of the target rail vehicle on the rail according to the transmitting time point and the receiving time point of the optical signal, and due to the fact that the transmission speed of the optical signal is high, the real-time performance and the accuracy of speed measurement and positioning of the rail vehicle are high; the potential safety hazard of the railway vehicle is eliminated; and the energy consumption is reduced.

    本发明公开了一种轨道车辆及其测速定位系统,属于轨道车辆领域,用于轨道车辆的测速定位。本申请在目标轨道车辆上设置了交变磁场发生装置,如此一来,随着目标轨道车辆的运行,光纤上间隔设置的振荡装置便能够在交变磁场发生装置产生的交变磁场的感应下产生谐振并对光纤中传输光信号进行反射,而光信号处理模块就可以根据光信号的发射时间点以及接收时间点计算目标轨道车辆当前的速度以及在轨道上的位置,由于光信号的传输速度较快,因此本申请中对轨道车辆进行测速定位的实时性以及准确性较高,消除了轨道车辆的安全隐患并降低了能量消耗。
