Embodiment
[0022] like figure 1 As shown, a 25Hz track circuit acquisition system based on the two-by-two architecture uses a high-performance circuit board to replace the previous relay circuit, reducing construction and maintenance costs. The system includes interlocking lower computer IPS, interlocking maintenance station SDM, track circuit acquisition module TCIM-25, and full electronic communication module EIOCOM2. When collecting the status of outdoor track circuit equipment, the track circuit acquisition module TCIM-25 uses two FPGAs to sample the track signals, and sends them to two CPUs for calculation, and obtains the voltage, frequency and phase information of the track signals. The track occupancy or idle state is obtained after comparison with the known threshold. Then it is sent to the interlocking lower computer IPS through the full electronic communication module EIOCOM2, and the monitoring information of the track signal is sent to the interlocking maintenance station S...

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.
Description
technical field [0001] The invention relates to a railway signal equipment system, in particular to a 25Hz track circuit acquisition system based on a two-by-two-out-two architecture. Background technique [0002] In order to realize the acquisition of track circuit state occupancy or idleness and obtain track signal monitoring information, it is necessary to build more complex relay circuits and monitoring circuits to achieve this, which requires more relays and monitoring circuits in actual design and construction. These relays and monitoring circuits are expensive and will take up a lot of space in the machine room. In addition, when a relay fails, it cannot report to the police in time, which is inconvenient for on-site maintenance. Contents of the invention [0003] The purpose of the present invention is to provide a 25Hz track circuit acquisition system based on the two-by-two architecture in order to overcome the above-mentioned defects in the prior art, sample th...
