Abstract
This disclosure relates to an intelligent train wheel sensor including a permanent magnetic coil and a low-pass filter circuit, an amplifying and shaping circuit, an analog/digital conversion circuit, and an output interface and interface conversion circuit, which are connected to each other in turn. The analog/digital conversion circuit and the output interface and interface conversion circuit being connected to a micro-processing control unit. The permanent magnetic coil is further connected in turn to a rectifier and filter circuit, a power storage circuit, a charging control circuit and rechargeable batteries. The rechargeable batteries supply power to the low-pass filter circuit, the amplifying and shaping circuit, the analog/digital conversion circuit, the micro-processing control unit and the output interface and interface conversion circuit. Such intelligent sensor has high reliability, requires no external power supply, can be installed and maintained conveniently. Furthermore, such intelligent sensor can identify a wheel signal of a low-speed train.
