The invention discloses a railway interlocking signal management system, which includes a filter receiving module and a push-pull oscillation module. The filter receiving module receives an analog signal output by a railway interlock signal transmitting module. The pull oscillation module uses the switching properties of the transistor Q5 to charge the LC circuit composed of the capacitor C7 and the inductor L2, then the LC circuit oscillates and amplifies the signal frequency, and designs two adjustments, one of which uses the high-level conduction of the transistor Q3 to feed back the signal to the operational amplifier AR2 In the inverting input terminal, the operational amplifier AR2 compares and adjusts the output signal of the denoising circuit, and then directly feeds back to the inverting output terminal of the operational amplifier AR4 to reduce the output signal potential of the operational amplifier AR4. Similarly, the second channel uses the triode Q4 to feed back low power After the flat signal is followed by the operational amplifier AR3, it is directly compensated to the output of the operational amplifier AR4. On the basis of amplifying the signal frequency, the signal amplitude is stabilized, so as to ensure that the frequency and amplitude of the signal during transmission meet the channel standard.
