Description
technical field [0001] The invention relates to the technical field of signal measurement, in particular to a frequency shifting track circuit testing system. Background technique [0002] The railway track circuit is composed of steel rails, sending equipment and receiving equipment, and is used to transmit locomotive signal information from ground equipment to on-board equipment. The safe operation of the train is inseparable from the reliable operation of the track circuit, and the reliable operation of the track circuit is inseparable from its fast and accurate testing, so as to discover hidden dangers in time and troubleshoot faults. The existing frequency-shifting track circuit test device used in ordinary railways has poor stability, anti-interference performance, and low test accuracy, and cannot meet the needs of the development of electrified railways and high-speed railways. Contents of the invention [0003] In view of this, the present invention proposes a fa...
