Embodiment Construction

[0042] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention.

[0043] In order to achieve the above purpose, the present invention proposes a frequency-shifting track circuit system 01 , as shown in the figure, the system includes: indoor equipment 02 and outdoor equipment 03 ; the indoor equipment 02 includes interface equipment 021 and frequency-shifting equipment 022 .

[0044] The present invention is based on the interface equipment realized by the safety computer as the core, plus indoor equipment (including sending module, receiving module, direction switching module, analog network) and outdoor equipment (including tuning unit, matching unit, air core coil and compensation capacitor ) constitutes a closed-loop system.

[0045] The interface device 021 is used to receive the cont...

Abstract

The invention discloses a frequency-shift track circuit system. The system comprises indoor equipment which comprises interface equipment and frequency-shift equipment; the interface equipment receives a control command sent by coding equipment and returns track circuit system information to the coding equipment; the control command is sent to the frequency-shift equipment, a return signal returned by the frequency-shift equipment is received and analyzed, and whether a frequency-shift signal sent by the frequency-shift equipment is correct or not is judged according to the return signal; the frequency-shift equipment conducts signal modulation on the control signal, a frequency-shift signal of a rail train is generated, and the frequency-shift signal is sent to the rail train; the return signal, with respect to the frequency-shift signal, of the rail train is collected, the return signal is demodulated, and train track state information is obtained. According to the frequency-shift track circuit system, systematic management is formed for a frequency-shift track circuit, closed-loop control of the whole frequency-shift track circuit is achieved, and the security of the system is improved.

Description

technical field [0001] The invention relates to the technical field of track control, in particular to a frequency shifting track circuit system. Background technique [0002] The main function of the frequency-shifting track circuit is to realize track occupancy and idle inspection, and to send control commands to the locomotive. The current frequency-shifting track circuit mainly includes indoor equipment and indoor equipment. The indoor is composed of transmitters, receivers, analog networks, attenuators and other modules. The outdoor is composed of tuning unit, matching unit, air core coil and compensation capacitor. The transmitter of the indoor equipment sends the frequency-shifted signal to the rail, and the receiver receives the signal from the rail. The signal sending and receiving between each module are completed independently without mutual connection, and the signal security of itself is independently guaranteed without forming a system manage. For example, wh...
