Anti-electromagnetic-interference train wheel vibration measurement method based on axle box acceleration

The invention discloses an anti-electromagnetic-interference train wheel vibration measurement method based on axle box acceleration. In the method, a system composed of a supporting plate, a rubber sleeve, a wireless speed sensor, a wireless acceleration sensor, a wireless laser acceleration sensor, a signal receiver and a computer is provided. An end cover of a train wheel set is sleeved with the supporting plate, the sensors are fixed to the upper and lower ends of the supporting plate, the coefficient of wheel vibration in the train travelling process is measured through the sensors and transmitted to the receiver through a network module, and the relationship that the coefficient is varied along with train operating speed is finally obtained through the computer. Interferences which the wireless sensors are likely to suffer from are eliminated by combining software with hardware, vibration measurement data is subjected to trend correction through the wavelet trend correction method, and real-time monitor
