Abstract

The invention discloses a method for detecting the state of a tuning area of an uninsulated frequency-shift automatic block system, relating to a method for detecting the state of a tuning area of a track circuit. The method is designed for solving the problem that the detection on the state of a tuning area of the existing electrical resonant uninsulated frequency-shift automatic block system can not be realized. The method comprises the following steps: a transmitting apparatus sends voltage signals to a transmitting matching transformer FBP, and the matching transformer FBP carries out matching transformation on the voltage signals and then inputs the voltage signals to an uninsulated track; a receiving matching transformer JBP acquires a track surface voltage of a receiving end, carries out matching transformation on the track surface voltage, and then outputs the track surface voltage to a receiving apparatus; the receiving apparatus carries out filtering separation on the signals so as to obtain a tuning area voltage signal and a main track voltage signal; and the tuning area voltage signal is compared with the main track voltage signal so as to realize the detection on the state of the tuning area of the uninsulated track circuit. The method disclosed by the invention is suitable to be applied to the detection on state of the tuning area of the uninsulated frequency-shift automatic block system.

Description

technical field [0001] The invention relates to a method for checking the state of a tuning area of ​​a non-insulated frequency shifting automatic blocking system. Background technique [0002] With the rapid development of railway construction and the continuous improvement of train running speed and density, the train operation control system based on non-insulated track circuit as the basis of ground train information transmission has been widely used. The track circuit that reflects the idleness of the train has become a key link to ensure the safety information transmission of the vehicle system, and there are higher requirements for the track circuit. It is particularly important to realize the inspection of the tuning area occupancy, broken rail, and tuning equipment failure status of the electrical resonance non-insulated track circuit, which directly affects the driving safety. The state inspection technology of the tuning area that has been proposed at present is ...
