Track irregularity prediction system and method based on vibration acceleration axlebox

The present invention discloses a system and a rail irregularity prediction method based on the vibration acceleration axle box. The system comprises a pedestal acceleration sensors, rotational speed sensor pulse, the analog preprocessing circuit, A / D conversion circuit, an embedded system, a wireless network routing, PC. The axle box acceleration sensors disposed on the running gear axle box train running, the rotational speed sensor is provided in the pulse train axle cap, the axle box and a vehicle speed signal is a vibration signal axlebox rotation speed sensor pulses collected by the sensor vibration acceleration collected analog preprocessing circuit to go through a low-pass filter process, and then processed by A / D converting circuit converting the analog signal into a digital signal, the digital signal is sent by the embedded system via a wireless network routing upper computer, the host computer via the vibration signal prediction get track irregularity results. The present invention has a low cost, and good engineering implementation.
