The embodiment of the invention provides a wheel sensor, a train detection system and a train running track. The wheel sensor is arranged on the train running track, and the wheel sensor comprises a first coil, a first signal processing circuit, at least one second coil and a second signal processing circuit, wherein the first coil is used for generating a first magnetic field, and when a train runs on the track, the first magnetic field is changed to generate a first electric signal; the first signal processing circuit is electrically connected with the first coil and is used for generating adetection signal for detecting running characteristics of the train according to the first electric signal; the at least one second coil is used for generating a second magnetic field, and the secondmagnetic field is changed to generate a second electric signal when the train runs on the track; and the second signal processing circuit is electrically connected with the at least one second coil and is used for generating a first power supply signal required by operation of the first signal processing circuit according to the second electric signal. According to the embodiment of the invention, construction cost is reduced, anti-interference performance is improved, a fault rate and a maintenance workload are reduced, and detection of the running characteristics can be effectively ensured.
