A lot of details are set forth in the following description so that fully understand the present invention.But the present invention can implement to be much different from alternate manner described here, and those skilled in the art can do similar popularization without prejudice to intension of the present invention in the situation that, and therefore the present invention is not subject to the restriction of following public concrete enforcement.
The invention provides a kind of train operation curve method of adjustment, between station, establish multiple checkpoints; Train Schedule between two stations that the ATO system in train issues according to ATS system calculates train run curve, and determines the plan time of advent of the each checkpoint between described two stations; And described ATO system is adjusted train operation curve according to the train actual time of arrival of checkpoint the time of advent with planning.Those skilled in the art can understand, thereby can adjust time of run between the station of train by adjusting described train operation curve, because ATO system is adjusted train operation curve according to true train time of run,, when train ATO system is during by train operation curve controlled train operation after adjusting, can improve the punctuality rate of train arrival.
As preferred embodiment, between two described stations, be between continuous two platforms; Checkpoint described in each is uniformly-spaced built between two stations, is appreciated that those skilled in the art can adjust as required the location gap of checkpoint and not depart from the scope of the present invention in practice.
Fig. 1 shows the train operation curve method of adjustment of the embodiment of the present invention, and the method comprises the following steps:
Step S1: establish multiple checkpoints between station.
Described ATO system generates the information of each checkpoint according to known line information, line information can obtain from track data storehouse, from track data storehouse, obtain the shortest time of run moving between station simultaneously, the information of described checkpoint at least comprises the position of each checkpoint, arrive the shortest reach time of each checkpoint and can be assigned with the percentum of time from platform, which checkpoint has been travelled to for mark train the position of each checkpoint, thereby be convenient to locate and obtain corresponding information, the percentum that arrives the shortest reach time of each checkpoint and can be assigned with the time from platform is for calculating plan time of advent of train of each checkpoint.
Train Schedule between two stations that step S2:ATO system issues according to ATS system calculates train run curve, and determines the plan time of advent of the each checkpoint between described two stations.
Step S2 carries out from platform at train, Train Schedule and the shortest described time of run between two stations that ATO system issues in conjunction with ATS system obtain distributing the time, and described ATO system determines that train arrives the formula of plan time of advent of each checkpoint and is:
plan_reach_time=least_reach_time+distributable_time*percentage
Plan_reach_time is for planning the time of advent; Least_reach_time is the shortest reach time; Distributable_time is for can distribute the time; Percentage is percentum.
According to one embodiment of present invention, described plan also can be issued by ATS system the time of advent.
Step S3: described ATO system is adjusted train operation curve according to the train actual time of arrival of checkpoint the time of advent with planning.
When train travels to checkpoint by run curve, the ATO systematic comparison train actual time of arrival and plan the time of advent, if the absolute value of both differences exceedes predetermined threshold value, ATO system is changed train operation curve according to the train actual time of arrival, otherwise do not change train operation curve, train continues to travel according to the run curve of not changing.Predetermined threshold value can be set by those skilled in the art, and after consideration error component, numerical value is chosen suitably.
Step S4: after train operation curve is changed, ATO system recalculates the plan time of advent (optional) of follow-up each checkpoint.
Train driving performs step S3 and step S4 during to each check point again, until when train in-track platform, re-execute the step S1 to S4 in the present embodiment, according to embodiments of the invention, preferred mode is all to establish multiple checkpoints between all platform, can guarantee that the run curve of train in the process of automatic train operation and actual train operation curve more press close to, thereby improve the punctuality rate of train, certainly, according to putting into practice requirement, also can between the platform that need to set up checkpoint, set up multiple checkpoints.
Fig. 2 be former run curve A, the actual operation curve B of the embodiment of the present invention and adjust after run curve C between be related to example, in the present embodiment, train is sailed to platform P2 from platform P1, between platform P1 and platform P2, be provided with 10 checkpoint CP1, CP2 ... CP10, from Fig. 2, train is before platform P1 sets out, ATO system basis is from the platform P1 of ATS system acquisition to time of run the station of platform P2, calculate run curve between the station of mating with this time of run, be former run curve A, and determine the plan time of advent of the train of each checkpoint.In the time that ATO system control train is pressed former run curve A operation process CP1 to CP5, the difference that train arrives the actual time of arrival of each checkpoint and plans the time of advent is in pre-set threshold value, and therefore ATO system control train continues to press former run curve A operation; In the time that ATO system control train operation arrives CP6, detect the actual time of arrival be less than plan the time of advent, and the absolute value of both differences is greater than pre-set threshold value, arrive this checkpoint too early, train driving need slow down speed during to rear, thereby ATO system adjusts the plan run curve after CP6, the run curve C after adjusting adjusts plan time of advent of CP7-CP10 simultaneously; When run curve C after ATO system is pressed adjustment moves through CP7-CP10, the difference that inspection train arrives the actual time of arrival of each checkpoint and plans the time of advent is in pre-set threshold value, and the run curve C that ATO control train continues to press after adjustment moves.In Fig. 2, also list the actual operation curve B of train in contrast, as seen from the figure, after the run curve of train being adjusted in the time that train arrives CP6 by the present invention, train is according to the run curve C operation after adjusting, real-world operation is as the actual operation curve B in figure, and train will arrive at a station on schedule; If run curve is not adjusted in the time that train arrives CP6, still according to former run curve A, differ far away with guarantee the actual operation curve B that train can arrive at a station on schedule, the speed that is train can be faster, also be more early in-track platform of train, thereby cause the decline of punctuality rate, facts have proved that arrival time that the present invention makes train by ATO system to the adjustment of Train Schedule more on schedule.
Although the present invention with preferred embodiment openly as above; but it is not for limiting claim; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible variation and modification, therefore protection scope of the present invention should be as the criterion with the scope that the claims in the present invention were defined.
