Detailed description of the invention
Below will coordinate graphic and embodiment to describe embodiments of the present invention in detail, by this to the present invention asThe implementation procedure that what application technology means solves technical problem and reaches technology effect can fully understand and according to thisImplement.
As shown in Figure 1, providing embodiments of the invention one below sets forth based on symbol guide derivation design drawingMethod, as described in method comprise:
Step S101: make symbol guide file according to Resource Properties and atural object attribute in advance.
Make symbol guide file according to the corresponding relation of described Resource Properties and atural object attribute and the Symbol Style;
Described symbol guide file is specific layout design form;
Described Resource Properties comprises service attribute and space attribute;
Described atural object attribute kit is containing Style Attributes and space attribute.
It should be noted that, Resource Properties and atural object attribute can come from the information that uses both sides to appoint,Also can come from existing attribute information in resource management system, can determine these according to actual conditionsThe source of attribute information, and make symbol guide file as standard.
Symbol guide file specifically layout design form is made, and third party easy to use like this establishesMeter software is opened this file and designs according to this file. Third-party design software including, but not limited toAutoCAD, symbol guide file format is including, but not limited to DXF file format.
The service attribute of Resource Properties mainly including but not limited to title, type of service, size, size etc. withThe attribute of traffic aided, and space attribute, include but not limited to space geometry type, coordinate system coordinate etc. withThe attribute of spatial information is described.
Same atural object attribute also has similar feature.
Step S102: the resource object set in Gains resources management system is also carried out space conversion, root to itObtain the corresponding money of each resource object according to the attribute information of described symbol guide file and described each resource objectSource symbol object.
Resource management system is managed nearly all resource object, in the time carrying out design drawing conversion, and Ke YixuanSelect the resource of a subsystem and carry out drawing protract, therefore need in resource system, obtain these target resourcesThe set of object.
Resource object in resource management system is presented on GIS map, and the coordinate system that GIS map adopts hasMay be spheric coordinate system, and therefore the plane right-angle coordinate that design drawing all adopts need to carry out spaceConversion, carries out the conversion of coordinate system.
Symbol guide file is the design drawing that meets of making according to resource object attribute, earth object attributeThe file of paper file description rule therefore, after Gains resources object, can obtain this in symbol guide fileThe corresponding resource symbol object of resource object.
Step S103: according to the earth object set on described resource object set background extraction map and to itCarry out space conversion, obtain various places according to the attribute information of described symbol guide file and described each earth objectThe corresponding cultural symbol object of thing object.
Earth object on GIS map has a lot, and the related atural object of design drawing is only a part wherein,Therefore the earth object set that needs delineation to obtain, these earth objects must be and resource object set geographyPosition is corresponding, exceeds the earth object of this scope not in the scope of obtaining.
Similar with the principle of step 102, need to carry out space conversion to earth object, equally at symbol guideIn file, obtain the corresponding cultural symbol object of earth object.
Step S104: by described resource symbol object, cultural symbol object and space transitional information combination producingDesign drawing file.
Space transitional information represented coordinate system that the design drawing file after conversion follows, scope, central point,Engineer's scale, resource atural object gland relation etc.
Resource symbol object, cultural symbol object composition are become to complete design drawing file together.
It should be noted that, can adopt multiple combination standard to carry out resource symbol object and cultural symbol objectCombination, as simple stack, combine, be subordinate to according to resource object business according to same subsystem modeRelation combines etc., can choose optimum combination according to practice.
In order better to set forth the present invention, provide embodiments of the invention two below, as shown in Figure 2:
Step S201: make symbol guide file according to Resource Properties and atural object attribute in advance.
Having made symbol guide file, is exactly the conversion foundation of arranging Resource Properties and atural object attribute in fact,Which type of symbol which type of Resource Properties converts to, has had symbol guide file, just can be according to symbolThe pattern of arranging in template file is changed.
Can make symbol guide file according to standard map form group code information, as according in DXF filespecGroup code carry out the making of symbol guide file.
Step S202: the resource object set in Gains resources management system is also converted to plane by its coordinate systemRectangular coordinate system.
It is background that resource management system has adopted GIS map, and the coordinate system of its use is likely flat squareCoordinate system or spheric coordinate system, therefore adopt described resource object according to the space attribute of described resource objectCoordinate mode be converted to plane right-angle coordinate, what just adopt if original was plane right-angle coordinate,Need not carry out the conversion of coordinate system.
In resource management system, can comprise a lot of resource objects, can be to belonging to the resource object of an operation system togetherCarrying out drawing derives operation, therefore needs to determine resource object set, can by resource system to businessObtaining of resource object set carried out in classification.
Step S203: obtain each money according to the attribute information of described symbol guide file and described each resource objectThe corresponding resource symbol object of source object.
Step S204: calculate institute according to the geographical location information of living in of each resource object in described resource object setState the boundary rectangle of resource object.
Design drawing can not be unconfined scope, according to the needs that design and represent, intercepts part and carries out itRemaining operation, therefore only need to obtain the drawing scope that includes resource object set can meet the demands, because ofThis calculates the boundary rectangle of described resource object according to the residing geographical location information of these resource objects, i.e. bagThe minimum rectangle that contains these resource objects.
Step S205: cut off the atural object space segment that exceeds described boundary rectangle scope.
Step S206: obtain the earth object set on its background map comprising according to described boundary rectangle.
Step S207: the coordinate mode described earth object being adopted according to the space attribute of described earth objectBe converted to plane right-angle coordinate.
In conjunction with described resource object space attribute, extraneous rectangular extent calculate described plane right-angle coordinate scope,The space transitional information of central point, engineer's scale, resource atural object gland relation.
Step S208: obtain various places according to the attribute information of described symbol guide file and described each earth objectThe corresponding cultural symbol object of thing object.
Step S209: by described resource symbol object, cultural symbol object and space transitional information combination producingDesign drawing file.
Described resource symbol object, cultural symbol object are combined to and are included according to certain priority relationshipIn the design drawing file of described space transitional information.
The priority relationship of combination can be set according to the multiple standards of practical application. As inferior in operation layer.
Step S210: use third-party design software to open described design drawing file, to described design drawingRepresent.
That third-party design software is the most frequently used is AutoCAD.
Provide implementation procedure of the present invention of the present invention below in conjunction with concrete instance in order more in detail clearly to illustrateEmbodiment tri-, as shown in Figure 3, illustrates in practical situations of the present invention.
Taking telecommunication resources management system as example, in telecommunication resources management system, managing a lot of telecommunication line moneySource, specifically can comprise website, machine room, electric pole, staff well etc., and these telecom cable resource actual distribution existThe geographical position that each is clear and definite, telecommunication resources management system exists according to the actual geographic position of these resources conventionallyOn GIS map, draw, to present the resource placement in specific region. For some specific scenes, canCan carry out more professional presenting and design to the resource in certain region, can adopt special designs drawing softwareAutoCAD carries out specialty and presents and design, and therefore needs to encourage the figure of drawing on GIS map and converts specialty toDesign drawing.
Because symbol guide file is made in advance, the resource of arranging what type in design drawing withWhich kind of pattern presents, and writes with general DXF file format, and symbol guide file can be at AutoCADIn directly open, as shown in Figure 4, shown in Fig. 4, be the example of part resource, when practical application not only forResource pattern in Fig. 4 presents.
Need to be with reference to DXF form while writing DXF symbol guide file, used some group codes hereContent, as BLOCK group code and ENDBLK group code.
BLOCK group code content is as shown in table 1:
Table 1BLOCK group code content
ENDBLK group code content is as shown in table 2:
Table 2ENDBLK group code content
In DXF symbol guide file about the related content (intercepting) as follows of " the original carriage release lever of SNG-":
In carrying out internal memory being judged before conversion of drawings, whether be written into the symbol guide in symbol guide fileObject, if there is no, can carry out and load all resources and background map the Symbol Style in symbol guide fileObject, if existed, can directly carry out step below. Money at this with " Taikang County Xie Anlu pipeline "Source is that example describes. Symbol guide DXF file is as follows, intercepts part.
Step S301: the resource object set of obtaining " Taikang County Xie Anlu pipeline ".
Can obtain corresponding resource object set by inquiry " Taikang County Xie Anlu pipeline " in resource system.The information (only intercept part, and conceal some attribute informations) as shown in table 3 of obtaining:
Table 3 " Taikang County Xie Anlu pipeline " the Resources list
In above-mentioned resource, be the line forming between well and well, have respectively starting point, terminal and line.
Step S302: the resource object in resource object set is carried out to space coordinate conversion.
The attribute information of each resource object is made up of business attribute information and space attribute information. Due toAutoCAD drawing is planar design drawing, therefore sits if the GIS coordinate system of resource system belongs to sphereMark, needs to carry out necessary space coordinate conversion, and spherical coordinate is converted to rectangular co-ordinate, and unit is with rice,Long measure retains decimal to 0.001 meter.
Here original is to adopt the spherical coordinate of WGS-84, and we convert it the right angle of Mercator projection toCoordinate system.
Step S303: according to the attribute information of symbol guide file and resource object, obtain each starting point, terminalSymbol object with line.
Point-like resource symbol pattern processing: starting point (terminal) resource is if pipe well resource type is used symbolDesignation " the newly-built carriage release lever of SNG-" in template file, enters according to the information of recording in symbol guide fileRow conversion; Its label character content sources resource name, that pattern font derives from appointment is title HZTEXTCAD font, height and width are all 3.5, width factor is 0.8, gradient is 0, marks the seat at centerCursor position equals the actual height of the deduct-text of Y-direction coordinate of endpoint location.
Starting point (terminal) resource is if machine room resource type is used the designation " JF-in symbol guideNewly-built machine room ", change; Its label character content sources resource name, pattern font derives from appointmentFor the CAD font of title HZTEXT, height and width are all 3.5, and width factor is 0.8, and gradient is 0,The Y-direction coordinate that the coordinate position at mark center equals endpoint location offsets downward the actual height of text.
The intermediate point of starting point and terminal does not have the Symbol Style, only carries out Coordinate Conversion.
Wire resource symbol pattern processing: comprise duct section, if resource section is duct section type, with successivelyConnection source, intermediate point, terminal are line segment, and width is 1, and color is green;
1) start position of line: carry out Coordinate Conversion;
2) final position of line: carry out Coordinate Conversion;
3) width of line: the initial sum of line stops width and all sets and be set as 0.6;
4) the fill style of line: line style adopts the ByLayer type of CAD, ratio 1, thickness is 0;
5) pattern of label character: font type is set to HZTEXT font, font height and width be 3.5,Calculate the anglec of rotation, guarantee word and line parallel, word center word is the Y-direction of line segment center point coordinateOffset downward the actual height of text, color adopts fuchsin.
Above-mentioned these the Symbol Styles, all on the books in symbol guide file, according to the attribute letter of resource objectBreath finds corresponding symbol object in symbol guide file, and record and completed coupling conversion, timeGo through all resource objects, it is mated after conversion one by one, matching result is recorded in DXF file.
Step S304: the boundary rectangle of computational resource.
Boundary rectangle can be regarded as the maximum abscissa in the each summit of given two-dimensional shapes, minimum abscissa,Maximum ordinate, minimum ordinate are fixed the rectangle on border. The scope of boundary rectangle can comprise all resourcesObject set, can obtain boundary rectangle by existing known algorithm.
Space beyond boundary rectangle just can cut off.
Step S305: obtain the earth object set in boundary rectangle, and it is completed to space coordinate conversion.
The scope of drawing that boundary rectangle is clear and definite, can obtain on the background map comprising from GISServerEarth object set, and then can know Style Attributes and the space attribute of each earth object.
If what earth object adopted is spheric coordinate system, need to be converted into plane according to its space attributeRectangular coordinate system.
Calculate rectangle and the central point of output: the rectangular centre point coordinates of AutoCAD view(1.2738939E7,4065560.5), width 97714.0, height 56163.0;
Calculate the engineer's scale of output: 1:1;
The gland relation representing between computational resource, between atural object: atural object is at bottom, between atural object priority be point,Line, face;
Resource line segment: in middle rank layer;
Point resource pipe well and machine room are in top.
Step S306: according to the Style Attributes of symbol guide file and earth object, obtain each earth object phaseThe symbol object of answering.
Point-like atural object pattern: point-like atural object adopts unified circle here, radius is 1, original coordinates is through turningCentral coordinate of circle is just set after changing, and dimension style is with pipe well resource points dimension style.
The conversion of linear ground object pattern: the unified multi-line section pattern that adopts AutoCAD here, select ByLayerLine style, live width adopts the ByLayer width of CAD, and color is set to ByBlock color, linetype scale 1.0,Thickness is 0.0, and mark is with pipe well resource points dimension style, but on the online middle point coordinates in center.
The conversion of area feature pattern: the unified multi-line section pattern that adopts AutoCAD here, select ByLayerLine style, live width adopts the ByLayer width of CAD, and color is set to ByBlock color, linetype scale 1.0,Thickness is 0.0; Mark is with pipe well resource points dimension style, but center is constructed how much on multi-line section summitOn profile center point coordinate.
Above-mentioned these cultural symbol patterns, all on the books in symbol guide file, according to the genus of earth objectProperty information, in symbol guide file, find corresponding symbol object, record and completed coupling conversion,Travel through all earth objects, it is mated after conversion one by one, matching result is recorded in DXF file.
Step S307: the spatial information of output conversion designs drawing file, by the resource symbol object obtaining andCultural symbol object outputs in this design drawing file.
Design drawing file is a DXF file, its spatial information coordinate system that above calculating obtains,The information such as scope, central point, engineer's scale. Finally form a DXF file, offered user and browseAnd download, can in AutoCAD, change the operations such as design.
Cultural symbol object and resource symbol object are merged while outputing in design drawing file, preferablyCan combine according to certain priority, this priority can be set according to actual conditions, here withThe combination priority level of Telecommunication Line Resource System is example. As shown in table 4 below:
