Problems solved by technology

This mode has a large amount of data in the background, and it is difficult to select the drawing space in the foreground, and every time a new type of wire is added, the maintenance of the background graphic element library is also doubled.
At the same time, due to the complex structure of distribution network lines, the design schemes of different areas are not uniform, the materials corresponding to different wire types of the same pole type are not uniform, and the accessories of pole towers are complex and diverse; therefore, it is necessary to maintain a large number of background databases
As the amount of data on club heads increases, drawing selection becomes cumbersome and the practicability of the software deteriorates.

Embodiment 1

[0040] see figure 2 , figure 2 The flow chart of the method for drawing distribution network lines based on CAD provided by the present invention is shown; the method for drawing distribution network lines based on CAD provided by this embodiment includes the following steps:

[0041] In step S101, the entity object in the distribution network circuit diagram is obtained, and the entity object is decomposed into towers, tower accessories and wires;

[0042] Wherein; the wire connecting the tower is represented by a straight line in the drawing area.

[0043] In step S102, generate a corresponding graphic metafile with the graphic element symbols corresponding to the tower and the tower accessories, and store it in the background folder in the CAD file format;

[0044] Wherein, the metafile is called into the drawing mode of the foreground, and is represented in the form of a meta symbol. In this embodiment, the metafile includes a tower graphic element and an accessory gr...

Embodiment 2

[0091] see Figure 4 , Figure 4 It shows the operation mode diagram of the CAD-based drawing method for distribution network lines provided by the present invention; this method introduces background metafiles with attributes, and the definition of a multi-head drawing method; with a small amount of background metafiles, various complex The distribution network line is drawn, and detailed engineering information statistics can be carried out; this embodiment adopts a small number of background metafiles to establish a primitive symbol database stored in the background folder, and the metafiles are provided with attribute labels. The drawing of the drawing area is also limited by the drawing rule of a long shot.

[0092] Among them, the background metafile with attribute labels includes five basic pole types in the distribution network lines, namely straight poles, reinforcing poles, tension poles, corner poles, and terminal poles. Depending on the level of the grid or the t...

Embodiment 3

[0104] The present embodiment provides the making process of the metafile in the background folder. First, the user determines the metafile to be established according to the actual situation; the establishment process of each metafile is specifically as follows:

[0105] 1. Create a new dwg file in CAD.

[0106] 2. Create a new layer and name it yin. It is hidden. If the added attribute label is not displayed, it will be placed in this layer when creating a new attribute label.

[0107] 3. In the default layer 0, draw the corresponding primitives.

[0108] 4. Add the att attribute tag. There are three types of attribute labels, which are model attribute labels, number attribute labels and text attribute labels. For example, according to the command of the att attribute label, enter the corresponding information in the label.

[0109] Model attribute label, used to collect the wire model;

[0110] Digital attribute tags, used to store digital information;

[0111] Text at...

Abstract

The invention provides a method and system for drawing a power distribution network based on CAD. The method comprises steps of decomposing an entity object in the power distribution network map into different types of pixel signs and straight lines, storing the pixel signs in a CAD file format in a background file and generating a pixel file, arranging the pixel file in a corresponding lead in a selected drawing layer, acquiring a lead type and storing the same into an attribute tag of the pixel entity, inserting the pixel entity into a lead end point position, and calculating and leading out drawing engineering statistic information based on the pixel file, the pixel attribute tag and the straight line length of the lead. In the drawing method, when the background pixel file is inserted into the drawing layer, the lead type can be automatically identified and stored into the attribute tag of the pixel entity object and a drawing method of one-rod-multi-heads is employed, so complicate pixel files storage due to various rod types and stay wires in the background can be simplified; and a method for optimizing drawing and calculation is provided.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a CAD-based method and system for drawing distribution network lines. Background technique [0002] The distribution network refers to the network that receives power from the transmission network and distributes it to the distribution substation, and supplies power to users through distribution lines. The main voltage levels of my country's distribution network lines are 10kV and 0.4kV. The power grid is a network composed of many distribution lines, and the distribution lines are composed of poles, pole switches, knife gates, ring network cabinets, switch stations, switching stations and other equipment. [0003] At present, the generation method of the distribution network circuit diagram is to use a graphic editing tool (GIS, CAD or other special distribution network graphic editor) to place the component symbols of the above-mentioned equipment on the diagram a...
