The invention belongs to the technical field of track circuits, and particularly relates to a method and system for reducing power consumption of a track circuit. The method comprises the following steps: acquiring carrier frequency and low frequency coding information; generating a frequency shift signal according to the carrier frequency and low frequency coding information; judging whether the frequency of the frequency shift signal is within a specified range or not; when the frequency of the frequency shift signal is within a specified range, the power of the frequency shift signal is amplified and then output, and the voltage and current amplitudes of the output signal are detected back; the amplitude of the output signal is reduced when the current of the output signal exceeds a threshold. According to the invention, the transmitting part and the receiving part of the track circuit adopt the same integrated circuit unit, so that the power consumption of the integrated circuit unit of the existing track
