METHOD FOR CORRECTING TRAIN POSITIONING ERROR IN WAYSIDE RADIO STATION

摘要

The present invention corrects the errors that can occur when determining the location of a train moving chain moving along a fixed route relates to a train position error correction method of the ground stations to determine the position more accurately. ; The present invention is to realize this, a reference signal is generated by the computer from the signal generator of the ground stations Each station is looking for the sample with the phase change in the sign of the phase information signal and the sampling signal phase, the reference signals are each sampled signal to extract the signal to be transmitted in response from the phase information signal to the ground stations of the receiver receives the reference signal phase, the sign is changed is zero, the size in the sample f (t) = calculating a 0, f (t) = 0 is the time of the reference signal t (t _a ) and f (t) t = 0, the phase information signal in the time (t _b ) using the time difference and obtaining a (t _b -t _a ), step of searching for the location of the on-board radio station on the time difference from the database of the earth stations, comprising an outputting a retrieved location information invention being characterized in that.
