Description
Technical field
The present invention relates to field of track traffic, relate in particular to a kind of controlling party of route triggering orderMethod and system.
Background technology
In recent years, city rail traffic signal system automation and intellectuality develop rapidly, trainAutomatic monitored control system (AutomaticTrainSupervision, ATS) is a kind of intelligent automaticMonitoring system, provides the control device of automation, to alleviate running scheduling personnel homework burden,Promote efficiency and the service level of metro operation.
According to traditional ATS, it is to trigger according to from the close-by examples to those far off carrying out order that route triggers. With Fig. 1Analyze, when train is set out by AB place, arrive to turn back in AC place or directly to passing through AFTime, according to the traditional method of current ATS, first to trigger route HE, and then trigger ECOr EF. But according to interlocking condition, if now trigger route HE, interlocking can be by track switchAutomatic blocking to location or antiposition: as being locked in location, if be about to handle be intoRoad EC, must before semaphore E, come to a complete stop until train (CBTC train can be after coming to a complete stop afterMeet immediately unlocking condition, if be non-CBTC train, need after 45S, meet unlocking condition)After could release track switch and handle EC route; If instead must handle route EF, track switch is lockedAlso be like this in antiposition.
Can find out according to above description, in existing mode, the protection section lock of being interlockedThere is the possibility that significantly reduces efficiency of operation in the difference of closing position. Particularly, for CBTCTrain efficiency of operation does not have too much influence, for non-CBTC train, needs elder generationStop the sufficient 45S additional time of moving switch locking route again, even if now come by manual intervention, also there is the drawback that operating automation degree is not high in walkthrough front route.

Detailed description of the invention
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, will tie belowClose the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention carry out clear,Intactly describe, obviously, described embodiment is the present invention's part embodiment, instead ofWhole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not havingMake the every other embodiment obtaining under creative work prerequisite, all belong to the present invention's protectionScope.
First the embodiment of the present invention proposes a kind of control method of route triggering order, referring to Fig. 2,Comprise:
Step S1: unique path of clear and definite train operation.
Step S2: judge whether described train exists the combine scenes of multiple route: when described rowWhen car does not exist the combine scenes of multiple route, enter step S3; When described train exists multipleWhen the combine scenes of route, enter step S4.
Step S3: preserve route data and carry out accordingly route and trigger order control, method stepFinish.
Step S4: extract the definite route combination in described unique path.
Step S5: be near-end route and far-end route by described route Combinatorial resolution, by described far awayEnd route is defined as the dependence route of described near-end route, and dependence route relation is stored.
Step S6: carry out route according to stored dependence route relation and trigger order control.
Visible, the route proposing in the embodiment of the present invention triggers in the control method of order, passes throughRoute combination, root are determined in unique path of specifying train operation in the comprehensive scene of multiple routeAccording to relying on route relation, the triggering order of route is controlled. The embodiment of the present invention has been improvedThe control method that order is triggered on road, has reduced manual intervention, has improved automaticity and operationEfficiency.
In one embodiment of the invention, preferably, can come according to route map of train clear and definiteThe operational plan of train, to determine unique path of train operation.
In another embodiment of the present invention, there is not the combine scenes of multiple route when trainTime, preferably, unique path of train operation can be preserved, according to preserved enteringCircuit-switched data is carried out route and is triggered order control.
In one embodiment of the invention, carry out the process of route triggering order control at ATSIn, preferably, can first learn train operation path by the data of reading pre-storedDependence route relation, in the time that Existence dependency route is related to, can be preferentially according to stored complying withRely route relation to carry out route and trigger order control.
In another embodiment of the present invention, preferably, carry out according to relying on route relationRoute triggers order control and can comprise: preferentially handle according to stored dependence route relationFar-end route, after far-end route is handled successfully, then handles near-end route, thereby ensures trainHigh efficiency operation.
Below taking the route triggering order control as the train of HE-EC-BA to operating path in Fig. 1Be made as example, describe the specific implementation of the embodiment of the present invention in detail, referring to Fig. 3:
Step 301: according to the clear and definite train operation plan of route map of train, determine that train operation onlyOne path.
In this step, carry out the operational plan of clear and definite this train according to route map of train. In the present inventionIn embodiment, the operating path of train is route HE, route EC, route BA, and train is wantedIn the operation of turning back of when operation, but not by operation.
Step 302: judge whether train exists the combine scenes of multiple route.
In the embodiment of the present invention, there is route HE, route EF and route in the circuit shown in Fig. 1, so there is the combine scenes of multiple route in HE, two kinds of route combine scenes of route EC.
Step 303: extract the definite route combination in unique path.
In the time that train exists the combine scenes of multiple route, need to extract according to route map of trainThe route combination that unique path is definite. According to the unique path of train definite in step 301, canWith clearly, in this section of route, the corresponding route of train is combined as route HE, route EC.
Step 304: determine and rely on route relation storage.
In this step, be first near-end route by route Combinatorial resolution corresponding unique train pathWith far-end route, and far-end route is defined as to the dependence route of near-end route, determine rely on intoRoad relation. In the embodiment of the present invention, route HE is the near-end route of this train under this scene,Route EC is far-end route. So route EC is the dependence route of route HE, the two foundationRely on route relation, and the above results is stored in the server that ATS uses.
Step 305: carry out route according to stored dependence route relation and trigger order control.
After above-mentioned Data Preparation completes, ATS is carrying out route while triggering order control,First whether learn Existence dependency route relation by reading stored data, when existence is complied withWhile relying route to be related to, can preferentially handle.
In the embodiment of the present invention, route EC and route HE are Existence dependency route relations, instituteWith in the time handling the control of route triggering order, first handle far-end route EC, at far-end routeEC handles near-end route HE again after handling successfully, in the time that train sails into, can directly enter like thisThe row operation of turning back, thus the high efficiency operation of train ensured.
So far, completed the control method overall process of the route triggering order of the embodiment of the present invention.
