The company has developed a railway wheel position detector with giant magnetoresistance effect, which belongs to the technical field of railway traffic signal acquisition and monitoring. The detector includes a U-shaped magnetic conductive circuit, a giant magnetoresistance sensor and a signal processing circuit board installed in a sealed casing, the resistance sensor is embedded in the magnetic gap of the magnetic flux gathering point of the U-shaped magnetic conductive circuit, and the resistance sensor is The output signal terminal is connected with the input terminal of the signal processing circuit board. The sensor of the utility model made of giant magnetoresistance effect has simple device and is insensitive to speed and frequency. The giant magnetic induction signal has a fast response, and the induction signal can not only adapt to high-speed trains, but also adapt to low-speed train wheel position detection until it stops. The railway wheel position detector with giant magnetoresistance effect has high sensitivity, good thermal stability and strong anti-electromagnetic interference ability.
