The invention relates to a 25Hz track circuit acquisition system based on a double 2-vote-2 architecture. The 25Hz track circuit acquisition system comprises an interlocking lower computer IPS, an interlocking maintenance station SDM, a track circuit acquisition module TCIM-25 and a full-electronic communication module EIOCOM2; the track circuit acquisition module TCIM-25, the full-electronic communication module EIOCOM2 and the interlocking lower computer IPS are orderly connected; the full-electronic communication module EIOCOM2 is connected with the interlocking maintenance station SDM; when acquiring the state of an outdoor track circuit apparatus, the track circuit acquisition module TCIM-25 samples track signals and calculates to obtain the voltage, frequency and phase information of the track signals, and obtains the result that the track is occupied or in an idle state after comparing the information with a known threshold; next, the result information is sent to the interlocking lower computer IPS via the full-electronic communication module EIOCOM2, and meanwhile, sends the monitoring information of the track signal to the interlocking maintenance station SDM. Compared with the prior art, the 25Hz track circuit acquisition system based on the double 2-vote-2 architecture has the advantages of greatly improving the reliability and the maintenance of the system, realizing the integration of safe acquisition and monitoring, and the like.
