Anti-interference wheel sensor

An anti-jamming vehicle wheel sensor is provided. The utility model is mainly adopted to detect the railway vehicle wheel signal and consisting of a magnet, an induction part arranged in the magnet and a signal treatment circuit unit connected to the induction part; wherein the input end of the signal treatment circuit unit is connected to the output end of the induction part; wherein the induction part is a hall sensor; and the signal treatment circuit unit is provided with a signal amplification and adjustment circuit; and the magnet takes the U shape; for the characteristics of the hall induction that the output signal is free from the jamming of external electric field change and the induction precision is relatively high, the utility model can be adopted to radically overcome the defects of the traditional vehicle wheel sensor that the anti-jamming capacity is poor and only the detection can only be carried out at the high speed instead of low speed, thus satisfying the diction requirement at the speed of 0 to 300km/h, and improving the detection precision of the railway train running parameter and the safety of the running train.
