Embodiment 2
Refer to Fig. 4, Fig. 4 be shown as provided by the invention based on CAD to distribution network line drawing practice operational mode figure; This method introduces the backstage metafile of band attribute, and the drawing practice definition of a bar bull; With a small amount of backstage metafile, the distribution network line completing various complexity is drawn, and can carry out detailed engineering information statistics; The present embodiment adopts a small amount of backstage metafile to set up to be stored in the pel symbol database in background folder, and this metafile is provided with attribute tags, and draw at drawing area to be also subject to the restriction of the drawing rule of a bar bull simultaneously.
Wherein, the backstage metafile of band attribute tags comprises five kinds of basic rod-type in distribution network line, is respectively straight line pole, stiffener, tension-resistant rod, angle pole, terminal pole.Different or wire type is different according to electrical network grade, the material that it uses is different.As tension-resistant rod because its place environment is different, be divided into again 1KVJKLJYG-70 tension-resistant rod, 10KVJKLGYJ-95 tension-resistant rod, 10KVJKLGYJ-240 tension-resistant rod etc.Therefore, may there is different bar heads in same rod-type title, and the material of correspondence is different.
The Graphics Mode that the present embodiment provides only represents with a pel symbol on backstage with corresponding metafile for similar figure metasymbol, and add ATT attribute tags as required.When on the wire being called to plot space, the wire type of placement location can be stored in the attribute tags of pel entity object.Same pel, when plot space generates different attribute according to the lead location of placing, achieves the polynary instantiation of metafile; As foreground plot space needs to call 1KVJKLYG-70 tension-resistant rod, backstage stores only a tension-resistant rod head being with attribute tags, when being inserted on 1KVJKLYG-70 wire, then can generate the tension-resistant rod head of band 1KVJKLYG-70 attribute; Again by pel entity diversified in the drawing area of foreground and database matching of getting the raw materials ready, can realize standby go out material function, in like manner 10KVJKLYG-95 tension-resistant rod and 10KVJKLYG-240 tension-resistant rod etc. are also by the tension-resistant rod head Element generation of a band attribute in backstage.
The metafile that the present embodiment provides is definable three types attribute tags in the metafile on backstage, for meeting the diversified demand of Distribution system design.Wherein, model attribute tags is for storing wire type;
Number attribute label is used for storage of digital information, and in distribution network line drafting, wire is with physical length scale, but some situation cannot be drawn in proportion, as the length of entrance line, the bracing wire length etc. of passageway bracing wire.For meeting this kind of specific demand, under making when family table case metafile and passageway bracing wire metafile, number attribute label can be added wherein, for storage of digital information.
Word attribute label is for storing Word message, and in order to use a small amount of backstage metafile as far as possible, some identical pel represents different entities in drawing.Have holes, four holes, six holes, nine holes etc. as shown case, its expression way is made up of a square, then represents the feature of its different hole count by text description.If each table case is all based upon backstage, eight metafiles at least to be set up, set up too much metafile and be unfavorable for Fast Drawing principle, therefore, set up unique corresponding table case pel, to add word attribute label to store Word message in the attribute tags of this table case pel, when being invoked into plot space, input hole count.The function of drawing with statistics is completed to realize less backstage metafile.
The drawing rule of one bar bull is as described below:
Often can occur diversity bar head in distribution network line, modal as joint used, and for example, namely likely there is some adjuncts in same shaft tower in straight line T extension bar, strain insulator T extension bar etc.If establish employing one bar one head mould formula, so above-mentioned band T extension bar head, to joint use and how complicated bar head all needs to define on backstage, increase the capacity of background data base; If adopt the Graphics Mode of a bar bull, then can at the metafile reducing background maintenance.
One bar bull drawing practice is as follows:
Shaft tower metafile or other metafiles are all inserted on wire end points and realize that a shaft tower has multiple bar head; But same position does not allow insertion two shaft tower class metafiles.
Bar head is divided into mobile jib head and time bar head simultaneously, and do to give a definition to mobile jib head: same bar head only allows interpolation mobile jib head, or does not add, but multiple bar heads and other adjuncts can be added, therefore, the quantity of straight line pole head is calculated in the following manner;
Straight line pole head quantity=with the shaft tower Shuo Liang – of wire type is with the mobile jib head quantity of wire type.
Embodiment 3
The manufacturing process of the metafile during the present embodiment provides background to press from both sides, first user determines according to actual conditions the metafile needing foundation; Described in each metafile process of establishing is specific as follows:
1, newly-built dwg file in CAD.
2, newly-built layer, called after yin.It is hiding, shows, then, during New anyAttribute label, be placed in this layer if the attribute tags of adding is not done.
3, in acquiescence layer 0, draw corresponding pel.
4, add att attribute tags.Attribute tags has three kinds, is respectively model attribute tags, number attribute label and word attribute label, such as, according to the order of att attribute tags, inputs corresponding information in label.
Model attribute tags, for gathering wire type;
Number attribute label, for storage of digital information;
Word attribute label, for storing Word message.
5, according to arranging demand, display properties label, when described attribute tags needs display, then attribute tags is placed on 0 layer, when described attribute tags is without the need to showing, then attribute tags is placed in yin layer.
6, DWG file is kept in background folder.
7, metafile naming rule is determined because of program, and the naming rule of this program is " type _ index number _ pel name dwg ".
Embodiment 4
The distribution network line that the present embodiment provides is drawn and is comprised initialization module, graphics module and statistics output module;
Initialization module carries out according to the following steps:
First, read backstage layer initialization document, read inner map data mining platform, in the drafting interface that foreground is corresponding, set up corresponding layer.
Wherein, this layer specifically comprises:
Pel layer: place pel entity object during for drawing.
Yin layer: for hiding the primitive attribute label not needing to show and print, and and the foundation correspondence of backstage metafile.
Mark layer: for filling in markup information, as bar number, line length, legend etc.
Leads layer: dissimilar wire is drawn in different layer, program is also identify dissimilar wire according to the difference of layer.Leads layer is multiple layer, and how many and add by user's wire type according to demand, its layer naming method is wire type
Secondly, after layer initialization, generate wire layer table with wire layer title, wire layer table is stored in internal memory for subsequent use.
Finally, read the title of dwg files all in background folder, it is classified, generate chained list, this chained list is stored in internal memory for subsequent use.
In the corresponding layer that graphic plotting completes at initialization module by graphics module, e.g., wire is plotted in wire layer, and pel is plotted in pel layer; By being stored in wire layer table in internal memory and chained list in initialization, ensureing that wire is plotted in corresponding wire layer, making backstage metafile call foreground and use.
The quantities information of the pel entity of completing added up by statistics output module, and export corresponding result.
Also comprise and arrange DCL panel module, this panel is used for user interactive.
