The company has developed a railway wheel sensor signal non-polar receiving and processing circuit and integrated chip, which are used in the field of railway signal processing technology. The railway wheel sensor signal non-polar receiving circuit includes: a first filter unit circuit, the input end is connected to the wheel sensor Both ends of the coil are connected to the wheel sensor signal, and the peak noise in the wheel sensor signal is filtered and then output to the first amplifying unit circuit through the output end; the first amplifying unit circuit is used to filter the wheel sensor after the first filter. The signal is differentially amplified and then output; the second amplifying unit circuit is connected to the first amplifying unit circuit, and performs in-phase amplification on the differentially amplified wheel sensor signal and outputs the wheel sensor signal. The invention effectively solves the interference of the interference noise to the effective signal, thereby improving the reliability and acquisition precision of the vehicle counting axle.
