Description
Technical field
The present invention relates to railway art, particularly relate to a kind of method and device of dynamic handling railroad track shunting badness.
Background technology
Track circuit is used to the elementary cell to car team integrity checking.When track circuit is normal, when there being car team, this track relay falls, and picks up without this track relay during car team; There are two kinds of phenomenons: the first is presented as there is car team for fall without track relay during car team under track circuit failure; The second picks up for track relay when having a car team, and be presented as without car team, these phenomenon railway systems are called shunting badness.Under the fail-safe principle of railway territory, the fail-safe principle of operational railway circuit is: track circuit relay falls, at once effectively and think there is car team at respective carter section; Without its track section relay energized under route in interval or station, think that section is idle immediately, its respective carter section is without car team; Its route inner orbit section relay energized in station, just thinks that this section is without car team after needing interlocking equipment released by checking three sections to unlock it.So the first under its fault has car team without embodying during car team, though affect conveying efficiency, safety is protected.But the shunting badness under its fault or unlock phenomenon is in advance a kind of potential safety hazard of railway systems always.
And the interlocking equipment that in control station, Signal lighting and route inner orbit section unlock, according to released by checking three sections, the order of route inner orbit section is unlocked, once car team enter station track completely and station track section unlock after, if station track track section generation shunting badness, interlocking can handle the route that other car team enters this station track, then may cause car team accidents.In addition, released by checking three sections is as the unlock method of interlocking equipment to route inner orbit section, depend on track relay once fell and once picked up state, once though the actuating of relay of route inner orbit section meets released by checking three sections, but car team does not leave its track section unlocked completely, now interlocking equipment can arrange the route through this track section, and its route gather can cause the car team also on this unlock zone to be turned on one's side, thus causes life and property loss.
Along with the fast development of high speed railway, visitor's special train control central apparatus carries Wayside signal lighting controlling functions, its lighting computing depends on track circuit information, if there is its track relay of the track circuit section of car team to fall, when train control center controls the Signal lighting of this track circuit section of protection for allowing signal, namely the signal protecting this section when track section has car team is open, grant subsequent car team enters this car team track section, this is a kind of shunting badness phenomenon that signal control equipment exports, this situation can cause car team rear-end collision when occurring, 7.23 accidents as generation in 2011 are exactly this kind of situation.
Secondly, when car team is with higher than the overspeed of circuit permissible velocity, car team may be caused to overstep the limit and cause life and property loss, this situation is that the car team that hypervelocity causes shifts to an earlier date deorbit section, and this phenomenon need report to the police and process, and avoids accident to occur.As 4.28 accidents of 2008 and DJ5506 overspeed on October 13 in 2008, though hypervelocity does not have an accident but troubling, this situation is the shunting badness phenomenon in another meaning, and namely car team should not leave certain track section and in fact have left certain track section.
As fully visible, how to solve the shunting badness problem that track circuit causes, how to solve the problems such as the shunting badness of signal control equipment output, thus improve the safe operation of railway transportation production, this is those skilled in the art's important technology difficult problem urgently to be resolved hurrily, is also the global problem in this field.
