A New Anti-Interference Magnet Sensor

Abstract:

Anti-interference magnets sensor is used to railway wheel signal detection, it includes a magnetic field, a set which have induction to the magnetic field and the signal processing circuit which connect to the induction parts. In order to completely overcome the defect compared with ordinary wheel sensor in anti-interference, and not only adapt to measure the high speed train, but also adapt to measure the low speed train. We designed a kind of new wide response speed railway wheel sensor used giant magnetic resistance. It satisfies the requirements of detecting speed of 0km/h to 350 km/h, and improves the accuracy of detecting kinds of parameters in train. So it can ensure the safety of the train traffic[1-2].
