The weak signal detect approach based on chaotic oscillator is an useful scheme for the signal detect in strong noise circumstance.This paper proposes a method to use the chaotic oscillator frequency detection applied in railway UM2000.We use the Holmes's Duffing oscillator to detect the UM2000 frequency shift signal in mass noise circumstance.The experiment results demonstrate that the proposed method has preferable performance.
