摘要： PROBLEM TO BE SOLVED: To specify a position of an abnormal wheel for each axle, in a system detecting the wheel tread state of a railroad train based on a traveling sound.
SOLUTION: Main components of a detection system of a wheel tread state include: a sound collecting device disposed immediately under an elevated bridge; two beam sensors arranged along a rail tracks; an IC tag on the train and an ID tag reader along a railway line; and a signal processing means. The signal processing means takes out an AC waveform signal from sound signals collected by the sound collecting device, and passes it through a band pass filter of a predetermined frequency band to be an extracted waveform. The extracted waveform is collated with a train speed calculated from outputs of the beam sensors and axle positions determined from the unit number of the ID tag. The right or wrong of the wheel tread state can be detected for each axle, and of the detection data are transmitted to a management PC such as a vehicle site. The axle position is easily and correctly specified when the temporal rolling and abrasion of the abnormal axle is performed.
