Embodiment
As shown in Figure 2, the continuity protection route triggering method based on the destination may further comprise the steps in a kind of City Rail Transit System:
(1) system initialization arranges acquiescence continuity protection route overlap, Preset Time upper limit t;
(2) judge whether train enters overlap and trigger section, if yes, execution in step (3), otherwise interlock system CI does not set up overlap, and turn to step (11);
(3) judge whether main route is set up, if yes, execution in step (4), otherwise CI does not set up overlap, and turn to step (11);
(4) judge whether overlap sets up, if yes, execution in step (5), otherwise CI keeps existing overlap, and turn to step (11);
(5) CI sends the overlap lock request to automatic train monitor ATS, starts time meter simultaneously;
(6) ATS receives request back search destination information, if the direction that exists destination information then to calculate the overlap locking replies to CI, and execution in step (7), if there is not the overlap position of then returning acquiescence, and turns to (11);
(7) judge whether CI receives the overlap lock information, if yes, execution in step (10), otherwise execution in step (8);
(8) judge whether time meter has arrived preset time t, if yes, execution in step (9), otherwise return step (5);
(9) CI sets up the overlap of acquiescence, and turns to step (11);
(10) CI sets up overlap according to the destination, and turns to step (11);
(11) finish.
As shown in Figure 3, the direction information of our station CI and the mutual overlap of our station ATS is mainly passed through in the foundation of single interlocking area overlap (being that overlap and route are at same interlocking area).Enter overlap at train and trigger section, and after main route set up, CI sent overlap and sets up lock request to ATS, and begin an overlap simultaneously and set up timing; ATS is after the foundation request of receiving overlap, search for this overlap updrift side and trigger first interior train information of section, if this train has corresponding destination, then according to this destination information, calculate the direction of overlap locking, if train does not have destination number, perhaps other situation then provides the locked position of acquiescence; Before timing finishes, if CI confiscates the overlap direction information that ATS sends, then overlap is set up the position that is locked in acquiescence, set up by destination information if receive then.
As shown in Figure 4, stride the foundation of interlocking area overlap (be overlap with route at different interlocking areas, overlap is in the neighbour stands the CI zone) and then finished by the CI at neighbour station, the process of setting up of adjacent station CI and the process of our station CI are similar.The adjacent regional CI in station sends the overlap lock request to the ATS at neighbour station, the ATS at adjacent station provides train number, purpose information and position etc. according to our station, search for this overlap updrift side and trigger first interior train information of section, if this train has corresponding destination, then according to this destination information, calculate the direction of overlap locking; If train does not have destination number, perhaps other situation then provides the locked position of acquiescence.
Since the present invention increased ATS＜-interactive information of CI, in order not influence efficient, the length of section is set up in the triggering of overlap must consider the distance that train moves in the loss of time (t) that this interactive information produces.Under the Train Control pattern (hereinafter to be referred as CBTC) and reserve master mode (hereinafter to be referred as BM) based on communication, triggering distance of the present invention increases V on the basis of original triggering distance
m* t, as shown in Figure 5.Wherein, V
mBe the maximum speed that train on the circuit can reach, t refers to information transmission and handles the long time delay that consumes.
When overlap is (as shown in Figure 4) when standing interlocked control by the neighbour, the time that consumes is the longest, should also be that CI is triggering the maximum delay that overlap sets up simultaneously the time.Be illustrated in figure 6 as the time delays that single interlocking area overlap request is set up, be illustrated in figure 7 as and stride the time delays that interlocking area overlap request is set up, the trackside of DCS described in the figure is the time-delay of the other equipment of data communication system (DCS) rail.Above-mentioned Preset Time upper limit t is this time delays, and in this time delays, if do not receive the information of ATS, then CI is based upon overlap the position of acquiescence.
In the present invention, under the normal circumstances, CI can realize arranging according to ATS destination and current of traffic the protection section (when train is in route and triggers section) of different directions automatically when handling (artificial /) train route.When under degraded mode, when adopting automatic route mode route setting, ATS has under the situation of destination of train, still can be according to the destination of train number, and the direction that triggers corresponding overlap locking is consistent with follow-up entry direction.
The present invention is based on the train destination and trigger corresponding overlap, because the locking direction of overlap is consistent with the direction of next bar route, make that train does not need to wait for the overlap release time.Particularly under backup mode, train needn't wait for that the release time (approximately more than the 180s) of overlap just can directly arrange follow-up route, carries out corresponding operation.Suppose to move according to 1: 1 at big or small cross-channel, because there is the release time of overlap, former tracking interval best-case is 180s.After adopting the inventive method, Train Interval no longer is subjected to the restriction of overlap release time, can adapt at interval with the main track operation at interval, reaches 120s, and efficient has improved 33.3%, has improved the availability of efficiency of operation and system.The present invention triggers dissimilar continuity protection routes according to the destination of train automatically, has improved the Signal Products automatization level, and has not needed the operator manually to participate in, and has alleviated operator's workload and stress.
