The invention relates to a wheel sensor. The wheel sensor comprises a first magnetic sensitive sensor, a second magnetic sensitive sensor and a permanent magnet, wherein the first magnetic sensitive sensor and the second magnetic sensitive sensor are arranged on a working surface of the wheel sensor respectively, are located at each end of the working surface respectively and are parallel to each other; one end of the first magnetic sensitive sensor is connected with a power supply input end of the sensor and the other end of the first magnetic sensitive sensor is connected with one end of the second magnetic sensitive sensor; a node is used as a signal output end of the sensor at the same time; the other end of the second magnetic sensitive sensor is grounded; the permanent magnet is arranged in the sensor and is located under the first magnetic sensitive sensor and the second magnetic sensitive sensor. The invention further relates to a method for judging train moving parameters using the wheel sensor. The wheel sensor and the method for judging the train moving parameters using the wheel sensor have the following beneficial effects that the structure is simpler and the cost is lower.
