The invention discloses a railway interlocking signal management system, which comprises a filtering receiving module and a push-pull oscillation module, and is characterized in that the filtering receiving module receives an analog signal output by a railway interlocking signal transmitting module and is connected with the push-pull oscillation module; the push-pull oscillation module charges anLC circuit composed of a capacitor C7 and an inductor L2 through the switching property of a triode Q5, then the LC circuit oscillates and amplifies the signal frequency, two paths of adjustment are designed, one path is conducted through the high level of a triode Q3, and signals are fed back to the inverting input end of an operational amplifier AR2; the operational amplifier AR2 compares and regulates the signal output from a denoising circuit and directly performs feedback to the reversing output end of the operational amplifier AR4, and reduces the level of the output signal of the operational amplifier AR4. Similarly, the two paths of low-level signals fed back by the triode Q4 follow the signals through the operational amplifier AR3 and then are directly compensated to the output end of the operational amplifier AR4, the signal amplitude is stabilized on the basis of amplifying the signal frequency. Therefore, the frequency and the amplitude during signal transmission are ensured to meet the standard of a channel.
