Description
Technical field
The present invention relates to the technical field such as railway infrastructure status monitoring and railway security guarantee, relate in particular to a kind of track circuit shunting badness dynamic testing method and device.
Background technology
Track circuit be two one steel rails of track section of definition as wire, the rail gap at two ends is loaded onto insulant, power transmission equipment is installed in one end, power receiving equipment is installed in one end.When without car, the low current of being sent by sending end makes the relay excitation of receiving end, represents that track circuit takies without car; In the time having car, the low current of being sent by sending end is by vehicle wheel to short circuit, and the relay loss of excitation of receiving end, represents that track circuit has car to take.
Train occupation track (train enters two one steel rails of this track circuit), control desk shows that this section takies, and is called shunted state of a track circuit, train occupation track, control desk does not show to take or do not have and reliably shows and take, is called track circuit shunting badness.So-called track circuit shunting badness is exactly " pressing not dead ", " the losing car " or " white light band " being commonly called as, that is: in the time that train (locomotive) enters a certain track section, the track relay of respective segments is but still in excited state, demonstration green light and white lamp that now can be wrong on corresponding signal lamp and control desk, show that this track circuit has lost the function that track section seizure condition is checked.

(1) track-circuit signalling transmission characteristic parameter detects, and comprising: track circuit section entrance, outlet voltage, track-circuit signalling transmission rail surface voltage, track circuit sending allowance detect.
(2) track-circuit signalling spectral characteristic parameter detecting, comprising: the detection of carrier frequency, frequency deviation, low-frequency information distribution and code order.
Track-circuit signalling is the STM to front installation (track circuit induction) antenna by the vehicle-mounted first round, receives and forms induced signal.Induced signal is sent into detection system track circuit acquisition processor by signal cable.Track circuit acquisition processor carries out dissection process to signal.
Existing track circuit detection system realizes parsing and the processing of the current conditions to track circuit transmitting terminal, can find that track circuit disturbs, falls the functions such as code, frequency shift (FS), building-out capacitor inefficacy judgement, but not there is the arbitration functions to track circuit shunting badness.
When car business personnel find after the bad section of doubtful track circuit, report to electricity business section maintainer, carry out on-the-spot test by maintainer.Current track circuit shunting badness test judging means mainly contains:
(1) utilize microcomputer monitoring to have access to test;
(2) use residual voltage tester test along separate routes;
(3) use 0.06 Ω or 0.15 Ω standard by-passed resistor line along separate routes, use multimeter or microcomputer monitoring to have access to test tracks circuit shunt residual voltage.
As fully visible, these methods of prior art all need field worker to test at indoor or outdoors, and workload is very large, can not carry out track circuit shunting badness dynamic test to all sections of system-wide in time.
