[0060] Preferred Embodiment

[0061] Taking the inter-town high-speed railway as an example, according to the TB / T10059-2015 Railway Engineering Graphic Symbol Standard, the designer imports the pre-prepared engineering data graphic symbol block in the AutoCAD drawing, mainly including station, signal machine, track section, balise, TCC boundary and other blocks with attributes, and draws the inter-town line section signal plane layout according to certain design rules. The block object attributes are as shown in the following table:

[0063]

[0064]

[0065] After the drawing is completed, in the graphic area, click the "Export Engineering Data Table" menu through the right mouse button menu, pop up the "Select File Directory", select the directory after selection, and the system extracts the block data in AutoCAD, sorts the X and Y axis coordinates of the block data to form an ordered list, extracts the attributes of the block data, processes into engineering data table business model data, and finally exports the engineering data table business model data to Table 3 Main Line Signal Data Table and Table 4 Balise Position Table. As shown below:

[0066] Station information: Dongji Station, District = 103, Subdistrict = 6, Station Number = 03

[0067] Signal block: SYMBO_11, NAME = F0025, LOCATION = DK2+574, DIVIDE_LINE = 1

[0068] Track section block: FREQU_1, FREQUENCY = 2300-2, LENGTH = 943m, CAPABILITY = c = 25uf*121 = 76.2(X1LQAG).

[0069] Balise block: Balise_110, NAME = B0023 / 7-DW, LOCATION = DK2+375 Table 3 Main Line Signal Data Table

[0070]

[0071] Table 4 transponder position table

[0072]

[0073] After the on-site measurement by the construction technician, the measured length of the X1LQAG track section is 944 meters, which is 1 meter longer than the original design length, and the revised main line signal data table is shown in Table 5. At this time, the design drawing needs to be changed.

[0075]

[0076] In the graphic area, click the "update drawing" menu in the right mouse menu, and select the revised data directory. In the first step, the system converts the data block information into an entity business model by extraction. In the second step, the system reads the engineering data table and converts it into an entity business model. In the third step, the system uses the Diif algorithm to identify that the track section block LENGTH attribute is modified from 943m to 944m, and then automatically updates the information of this block.

[0077] Finally, verify whether the design drawing (such as Figure 4 ) is updated synchronously. In the graphic area, click the "compare data" menu in the right mouse menu, and select the revised data directory. In the first step, the system converts the data block information into an entity business model by extraction.
