基于ARM技术开发了防止打伤钢轨装置,通过比较光电速度传感器和超声波测速传感器信号来判断机车车轮是否空转打滑。试验及使用结果验证了该装置的可靠性。
Based on the ARM technology, a rail device is designed to prevent injury. By comparing the signals of the photoelectric velocity sensor and the ultrasonic velocity sensor, the locomotive wheel is judged to be freewheeling. The test and the use of the results verify the reliability of the device.
