This paper introduces the applications of Digital Universal Cab Signaling in section of Axle Counting Automatic Block. This cab signaling adopted methods of digital signal processing (DSP)technique. The cab signaling can cover the two kinds of signals, intermittent frequency shift signal and single rail track frequency shift signal, in the section of the axle counting automatic block. Its device is fair safe and has highly reliability and anti interference.
