The invention provides a locomotive speed measuring device, which comprises an ultrasonic generator arranged at the front end of a locomotive head and used for transmitting ultrasonic waves to a rail; the ultrasonic receiver is arranged at the front end of the locomotive head and is used for receiving reflected wave beams formed after being reflected by the rails; the controller is in communication connection with the ultrasonic receiver and is used for receiving the reflected wave beam and determining the speed of the current locomotive according to the reflected wave beam; and the vehicle speed alarm module is in communication connection with the controller and gives an alarm when the vehicle speed of the locomotive exceeds a preset threshold value. The vehicle speed is measured through ultrasonic waves, so that the speed measurement error caused by wheel idling in the traction acceleration stage and wheel slipping in the braking deceleration stage of the locomotive can be effectively avoided, and the reliability is good.

    本发明提供了一种机车测速装置,包括:超声波发生器,设置在机车车头前端,用于向铁轨发射超声波;超声波接收器,设置在机车车头前端,用于接收经铁轨反射后形成的反射波束;控制器,与所述超声波接收器通信连接,用于接收反射波束,并根据反射波束确定当前机车的车速;车速报警模块,与所述控制器通信连接,当机车的车速超过预设阈值时,发出警报。本发明通过超声波完成车速的测量可以有效避免机车在牵引加速阶段时的车轮空转和制动减速阶段时的车轮打滑所造成的测速误差,可靠性好。
