Adopt back method of the present invention, as shown in Figure 1, first perform step S100, obtain the qualifications of playback shunting movement record.In the present embodiment, qualifications comprises target locomotive, playback duration scope, playback spatial dimension etc.Be understood that, in practical implementation, do not need to provide all qualificationss, or several in qualifications only need be provided usually.The a certain particular locomotive of such as playback all shunting movement record data in a period of time.Can the shunting movement record of playback specific time period or particular locomotive fast and accurately based on back method of the present invention, thus be convenient to carry out the analysis of shunting movement record data daily.
Then perform step S110, obtain shunting movement record based on qualifications.In the present embodiment, first corresponding shunting movement record is chosen according to qualifications.Then shunting movement record is resolved.In the process, need the numbering (title) filtering out all signals on locomotive operation path from shunting movement record, and the sequencing of signal on operating path.
Then step S120 is performed, based on qualifications acquisition station field pattern data file.Then perform step S140, draw yards design base map according to yards design data file.In step S140, first the present embodiment analyzes the yards design data file got, thus from yards design data file, extract the type of each unit and the position of correspondence on departures field.Then on yards design base map, draw corresponding icon according to the type of each unit and the position of correspondence on field, station, thus complete yards design base map.
In the present embodiment, the unit of standing on field comprises line segment, track switch and signal.Because the present invention is based on existing yards design data, the details type of each unit on field of therefore standing also with existing yards design data consistent, just repeat no more here.Coordinate points according to line segment, track switch and signal draws out each data type icon in software interface, corresponding line segment and track switch is connected, complete yards design of completing.Back method of the present invention is based on yards design playback shunting movement record, and playback result is more directly perceived, facilitates consultation and understands.
Next just can based on yards design base map according to shunting movement record playback shunting movement record.In the process, first perform step S130, obtain operating path step.In this step, the operating path of locomotive is obtained according to shunting movement record.Then perform step S150, operating path plot step, operating path is plotted on the yards design base map that obtains in step S140.Finally just step S160 can be performed, data readback step.The step S160 of the present embodiment not only comprises locomotive operation replay procedure and also comprises signal state replay procedure.Wherein, locomotive operation playback be recorded in yards design base map according to shunting movement locomotive operation path on according to dynamic drafting locomotive location information time lapse; The playback of signal state be recorded in yards design base map according to shunting movement operating path on according to the corresponding signal status information of dynamic drafting time lapse.
Based on the difference of on-the-spot running condition, locomotive has dissimilar operating path.Different playback qualificationss also causes the obtain manner of operating path different simultaneously.Therefore, in the present embodiment, the acquisition process of operating path is divided into several stages.When the data readback step (S160) in each stage terminates, need to perform step S170, playback terminates determining step.In step S170, judge based on playback qualifications the playback target whether current playback reaches predetermined.In time reaching predetermined playback target, it is yes that playback terminates determining step judged result, enters step S180, and whole playback operation terminates.
The present embodiment draws yards design according to the station number of shunting monitoring log file record, field dynamic loading yards design data file.Because a shunting monitoring log file may need to load multiple yards design data file to draw yards design, therefore the present embodiment also comprises step S190, carry over determining step.Be no when playback terminates determining step (S170) judged result, playback needs to proceed, and now enters step S190.
In step S190, judge whether the operating path of locomotive next stage crosses current yards design base map based on shunting movement record.When the operating path of locomotive next stage crosses current yards design base map, then carry over judged result is yes.Now again perform step S120, obtain yards design data file new accordingly based on shunting movement record.Then again perform step S130 based on new yards design data file, carry out the acquisition operating path step in next stage.When the operating path of locomotive next stage is on current yards design base map, then carry over judged result is no.Now directly again perform step S130, carry out the acquisition operating path step in next stage.
What the present embodiment adopted is the acquisition operating path step (S130) often completing a stage, just performs corresponding operating path and draws (S150) and data readback (S160) step.Be understood that, also can adopt the acquisition operating path step first completing all stages, then perform in entirety and obtain operating path and data readback step.
In another embodiment of the invention, the acquisition operating path step in a stage is first carried out.Then judge whether the path obtained reaches predetermined demand (S170).If do not reach reservation demand, then proceed the acquisition operating path (S130) in next stage.If the path obtained reaches pre-provisioning request, then all operating paths obtained are plotted on the base map of field, corresponding station (S150).Finally on drawn operating path, carry out data readback (S160).
Following continuation is described for the embodiment shown in Fig. 1.Because the obtaining step of operating path is in the present embodiment divided into multiple stage, thus each stage just obtaining operating path step be below described in detail.As shown in Figure 2, when obtaining operating path, first to perform step S200, obtaining initialize signal machine.In the present embodiment, from shunting movement record, obtain the record data of locomotive first signal of process on field, station, first signal is defined as initialize signal machine.According to order time lapse, extract the record data of first signal obtained in Fig. 1 step S110.
In actual moving process, the operating path of locomotive is divided into several different type.One of them type is initial path, initial path be locomotive from truck position (locomotive, truck position is generally positioned at native gear place) drive to before first signal between path.Be understood that, initial path is a path only comprising a signal, and signal is positioned at the terminal in path.Therefore, in the present embodiment, after execution step S200, need to perform step S210, judge whether comprise initial path in the required operating path obtained.
In step S210, according to the record data combining station field pattern data file of initialize signal machine that step S200 obtains, judge that whether initialize signal machine is the endpoint signal machine in initial path.If initialize signal machine is the endpoint signal machine in initial path, then perform step S220, combining station field pattern data file is according to the corresponding initial path of the record data acquisition of initialize signal machine.Then corresponding and initial path step S150 (operating path plot step), step S160 (data readback step) is performed successively.
When the data readback step (S160) for initial path completes or initialize signal machine is not the endpoint signal machine in initial path, next perform step S230, obtain current demand signal machine.In the process obtaining operating path, if step S230 performs first time, then the initialize signal machine obtained in step S200 is set as current demand signal machine.
Similar initial path, the type of the operating path of locomotive also comprises transition path.Last signal of current yards design of process that transition path is locomotive sails the path between the entrance of field, the next stop into locomotive.Be understood that equally, for field, a certain specific station, transition path is a path only comprising a signal, and signal is positioned at the starting point in path.Therefore the present embodiment also comprises step S240, judges whether to there is transition path.
In step S240, according to the record data combining station field pattern data file of current demand signal machine that step S230 obtains, judge that whether current demand signal machine is the home signal machine in transition path.If current demand signal machine is the home signal machine in transition path, then perform step S250, combining station field pattern data file is according to the corresponding transition path of the record data acquisition of current demand signal machine.Then corresponding and transition path step S150 (operating path plot step), step S160 (data readback step) is performed successively.Be understood that, namely locomotive sails out of our station field behind transition path.
The type of the operating path of locomotive also comprises local operating path.Local operating path refers to the operating path of locomotive between adjacent two signals.When judging in step S240 that current demand signal machine is not the home signal machine in transition path, the local operating path of locomotive next just can be obtained.In the present embodiment, first perform step S260, obtain front signal machine.Temporally passage to take out in turn in shunting movement log file relative to the record data of the next signal machine of current demand signal machine and the signal of taking-up is set as front signal machine.
Following execution step S270, obtains local operating path.In this step, obtain the local operating path of locomotive according to the record data of current demand signal machine and front signal machine based on yards design data file.It is the detailed process obtaining locomotive local operating path shown in Fig. 3.As shown in Figure 3, first perform step S400, setting current road segment.In step S400, first based on the section that yards design data file is corresponding according to the record data determination current demand signal machine of current demand signal machine.Then section corresponding for current demand signal machine is set as current road segment.
Following execution step S410, determines service direction, based on the service direction of yards design data file according to the record data determination locomotive of current demand signal machine and front signal machine.In step S410, the coordinate corresponding in yards design according to the record data acquisition signal machine of current demand signal machine and front signal machine.With the coordinate of current demand signal machine for origin coordinates, stop coordinate with the coordinate of front signal machine, calculate the service direction that locomotive is current.
Next carry out step S420, setting stops section.First based on the section that yards design data file is corresponding according to the record data determination front signal machine of front signal machine.Then section corresponding for front signal machine is set as stopping section.
Following execution step S440, determines section, front.In step S440, determine the section, front be connected with current road segment on the service direction of locomotive according to current road segment based on yards design data logging.In the present embodiment, section comprises line segment and track switch.
As shown in Figure 4, A, B, C and D are the schematic diagram of four kinds of line segments on yards design, represent four kinds of locomotive operation circuits respectively.Black line wherein in square frame is the circulation line of locomotive, wherein: A be level to; B is Vertical dimension; C is left to bottom right oblique; D is that the oblique of upper right is arrived in lower-left.Be understood that, several line segment head and the tail are connected the circulation line that namely can form one section of locomotive successively.
In yards design data logging, each line segment record comprises connected precursor section record and follow-up section record.If current road segment is line segment, then first determine that the section, front of current line segment on locomotive operation direction is precursor section or follow-up section.Then the precursor section that acquisition is connected with current road segment from yards design data logging or follow-up section are as section, front.
The connection mode of the track switch on locomotive operation circuit is different from line segment.Now describe for a simple track switch type.Figure 5 shows that the schematic diagram of a simple track switch unit.In figure, the part of black line is the travel line of locomotive.Can be seen there is route 501 with unit center O for starting point fails to agree by Fig. 5, have route 503 to the right, have route 502 to upper right.Route 501,502,503 is intersected in O point.Definition 501 is railroad turnout base position, and 503 is track switch location, and 502 is track switch antiposition.
If current road segment is track switch, then need first to judge the connection location of section on the reversing sense of service direction and current road segment.If last section connects location (503) or the antiposition (502) of track switch, then obtaining the section connecting railroad turnout base position (501) is section, front; If last section connects the base position (501) of track switch, need to carry out search to determine section, front.Choose the location (503) of track switch or antiposition (502) as entry direction, search for the section be connected according to service direction successively.If the section that front signal machine is corresponding can be searched, then obtain the section that connect corresponding to entry direction as section, front.In search procedure:
1) if the search carried out along the section be connected enters the reversing sense of service direction, then the entry direction mistake of current search, needs to reselect entry direction;
2) if on service direction, current search to the position in section exceed the position in section corresponding to front signal machine, then the entry direction mistake of current search, needs to reselect entry direction;
3) if on service direction, search the section that signal beyond front signal machine is corresponding, then the entry direction mistake of current search, needs to reselect entry direction;
4) if search for the section be connected less than the next one, then the entry direction mistake of current search, needs to reselect entry direction.
In the present embodiment, take first to search for antiposition (502), then the mode of searching for location (503) is searched for.
In step S440, after getting section, front, first the record data in the section, front got are stored, then perform step S450, judge that whether section, front is consistent with termination section.If section, front is inconsistent with termination section, then perform step S460, upgrade current road segment.In step S460, the section, front obtained in step S440 is set as new current road segment.Then again perform step S440 based on new current road segment, obtain new section, front.And step S450 is performed to new section, front.
If section, front is consistent with termination section, then perform step S470, combination local operating path.In step S470, connect section corresponding to current demand signal machine successively and determine in step S440 and the section, all fronts stored, thus obtaining the local operating path between described current demand signal machine and described front signal machine.Now the acquisition operating path step in a stage also completes thereupon.
Local can perform the step S150 (drafting operating path) shown in Fig. 1 and step S160 (data readback) after obtaining operating path for the local operating path got.Operating path due to locomotive may comprise multiple local operating path, and therefore the present embodiment also comprises step S280 as shown in Figure 2, operating path determining step.In step S280, judge whether the final position in locomotive operation path crosses front signal machine according to shunting movement record.When the final position in locomotive operation path is before front signal machine or on front signal machine, then illustrate the locomotive operation of this playback terminate in front signal machine before or on.Now perform step S180 (playback terminates).
When the final position in locomotive operation path crosses front signal machine, illustrate that locomotive is crossed follow-up the continuing of front signal machine and sailed.Now need to carry out step S231, upgrade current demand signal machine.In step S231, a upper front signal machine obtained in the operating path stage is set as new current demand signal machine.Next again perform step S240 based on new current demand signal machine, thus start the acquisition operating path step of new stage.
In practical operation, stop the situation of data readback owing to running into midway sometimes.For this situation, the present embodiment adds step S290 between step S280 and step S231.After step S280 judges that the final position in locomotive operation path crosses front signal machine, first perform step S290, judge whether to there is interruptive command.If there is interruptive command, then directly enter step S180 (playback terminates); If there is no interruptive command, then proceed step S231.
