Referring to the embodiment shown in Fig. 1 ~ 4 as can be known, the method for a kind of automatic generator orbital traffic route database, its step is as follows:

The platform of step 1, the automatic generator orbital of establishment traffic route database, it comprises graphing module, graphic attribute load module, the preservation of XML file and load-on module and rail line circuit-switched data automatically-generating module;

Step 2: draw by the graphing module field pattern of standing, by the drafting of some fundamental figures with drag the station field pattern (railway network) that can draw the same with the CAD drawing, the fundamental figure type has comprised summit (expression wheel counting apparatus or track switch, frontier point), limit (expression track, mode by line between two summits is drawn), teleseme and platform form graph topology information.In the process of drawing the station field pattern, click icon at toolbar, clicking in the target location afterwards will be at the relevant position graphing, and each figure is represented this figure by unique ID of the overall situation of automatic assignment in internal memory simultaneously, records type and the coordinate of this figure simultaneously.For a limit, describe and the concrete coordinate of writing edge not with the starting point of drawing and terminal point.Because it is not very attractive in appearance just having begun the wiring diagram of picture, can adjust the position of existing graphics by drag function, for edge graph shape, so because be the position of representing with two summits that only need drag the summit, the limit will repaint.Wheel counting apparatus and track switch are abstracted into summit in the graph theory, track is abstracted into limit in the graph theory, and every limit can be calculated the ID that automatically identifies starting point and terminal point and represent the limit by these two summits according to the coordinate on the coordinate of mouse action position and summit when being drawn by computing machine.For example, if drawn a limit between summit 3 and the summit 5, in internal memory, will have one＜3,5 so〉the limit, the ID on this limit is 8, by this method, the topological diagram of track then can be expressed as a vertex set and the set of limit.

Step 3: utilize the graphic attribute load module that graphic attribute information is set, if click right on each figure of described drafting, can eject the attribute that a dialog box arranges each figure, this attribute is the essential information of corresponding each object just, these essential informations be exactly by before the data producers from the CAD drawing artificial cognition come out to be filled up to information in the data form.But in this way, thus since do not need to consider the mutual relationship typing between the figure information can than manual type lack much and very directly perceived being not easy make mistakes.

Step 4: utilize the preservation of XML file and load-on module to carry out the XML file and preserve and load, the set graph topology information of step 2 and step 3 and each attribute information all are kept in the middle of the internal memory, preserving and load by the mode of XML is the mode of a kind of good tissue and management data, because can the various information of structurized description, be convenient to expansion, readable good simultaneously, convenient management.Also can adopt Excel file or other file layout.Hold function is used for memory information is saved in disk, and value-added tax function is used for fileinfo is loaded into internal memory, conveniently various figures and attribute information is managed and revises.

Step 5: utilize the automatic generator orbital of rail line circuit-switched data automatically-generating module traffic route database; Be converted into the manageable form of computing machine through CAD information after step 1 ~ step 4, this step purpose just is to generate final track data storehouse on basis before., can be directly used in and generate final track data storehouse all in the middle of internal memory through the attribute information of the annexation of each figure after preceding four steps and each figure.Step 5 specifically may further comprise the steps:

(1) coefficient sets VertexEdgeRelation[is closed in the storage on establishment summit and limit], the track that is used for each left side, summit connection of storage is gathered, the track set that the right connects.If axle-counting points, the left side or the right only connect a track, and the words left side of switch point or the right can connect two tracks, so use track to gather to record the list of tracks that the summit connects.

(2) each limit of scanning limit set, search starting point and the terminal point on this limit, add this limit to the VertexEdgeRelation[starting point] the right connect in the track set, add this limit to the VertexEdgeRelation[terminal point simultaneously] the left side connect in the track set, through after this step, the track set that this left side, summit connects, the track set that the right connects have all been tried to achieve in each summit.

(3) each limit of scanning limit set, search starting point and the terminal point on this limit, for starting point, inquiry VertexEdgeRelation[starting point] inquire about the track set that this left side, summit connects, inquiry VertexEdgeRelation[terminal point] inquire about the track set that this right, summit connects, inquire about the attribute information on this limit self simultaneously and above-mentioned Query Result is merged, can obtain all properties information and the track link information of a track, obtain a record in the middle orbit sector table of final track data storehouse, scan after all limits finish, obtain all records in the track regions segment table.

For teleseme table, wheel counting apparatus table, track switch table, track regions segment table, platform table, only need the corresponding set of scanning, the attribute information that goes to inquire about corresponding figure according to the ID of figure can generate each last tables of data.
