Railway locomotive frequency shift signal carrier frequency and modulation frequency bearing the important information, in order to detect locomotive signal for high precision, this paper analyzes the locomotive signal characteristics, puts forward a new demodulation method, realizes locomotive digital frequency shift signal detection, and the four different carrier frequency signal automatic identification and automatic detection. Using MATLAB simulation, the results show that the method is effective, and carrier frequency and modulation frequency detection error are low. So this scheme can improve the railway locomotive frequency shift signal detection accuracy with high integration and high reliability.
