Description
Technical field
The present invention relates to field of computer technology, relate in particular to a kind of efficient distribution network structure drafting method.
Background technique
Distribution network structure is shown by distribution network structure figure by geographical background figure, facilitate produced on-site operations staff into
The operations such as row power equipment O&M, repairing and construction, wherein most important during power distribution network produces operation management.It draws at present
Method main method processed is used specific geographical area Baidu map through computer screen screenshot mode, and interception is at multiple figures by hand
Piece is conducted into CAD mapping software, and by being spliced into a complete area map, as distribution network structure
Geographical background figure, then on manual drawing power circuit and equipment to geographical background picture.
Inefficiency in existing manual method production geographical background figure manufacturing process, since specific region area at least also has
50 square kilometres, lower rank Baidu map can only be intercepted, causes geographical background figure background picture resolution ratio not high, in addition exists
CAD upper one section of one section of drafting power circuit and device efficiency by hand is relatively low, and can not manage the money of power circuit and equipment
Expect account.
Summary of the invention
The object of the present invention is to provide a kind of high-resolution backgrounds based on offline map system, efficiently draw rack figure
Distribution network structure drafting method.
In order to realize goal of the invention above-mentioned, a kind of efficient distribution network structure drafting method, comprising the following steps:
S100: building map supply quotient offline map system；
S200: configuration power equipment pel symbol database；
S300: it is plotted in offline map system from particular primitive is selected in pel symbol database；
S400: manual and/or automatic addition line between the pel symbol of adjacent drafting verifies the integrality of connection.
Wherein, the method that S100 constructs map supply quotient offline map system is:
S101: obtaining the offline map picture of map supply quotient, and the n picture of every level is successively stored in n storage catalogue,
Unified picture pixels size；
S102: the total pixel size of splicing picture of every level is obtained, the display of every level is obtained divided by current window pixel size
Scale bar；
S103: the maximum display scale ruler and minimum display scale ruler of all levels are obtained；
S104: the window coordinates system according to current display window field range is converted into Picture Coordinate system, passes through Picture Coordinate system
Read the picture and pel symbol under current display scale ruler within the scope of this；
S105: when currently now the display window visual field zooms in and out, being directed toward the corresponding level picture by display scale ruler, then
Load the picture in the region；
S106: when window coordinates system and current map coordinate system difference, S104 step is returned to.
Map supply quotient of the present invention includes but is not limited to Baidu map, Google Maps, sogou map, Amap
Any one.In S101, picture pixels unify size and be generally subject to 256 × 256 pixels be；Picture saves format
But it is not limited to the formats such as JPG, JPEG, TIF, TIFF, PNG.
When S300 of the present invention is by pel symbol plotting offline map system, the pel symbol of every level is offline with the level
Map picture is corresponding.Therefore, in step S106, when user's moving map, system detection to window coordinates system with
Current map coordinate system is different, returns to S104 step, reads the picture and pel symbol under current display scale ruler within the scope of this,
And line be connected automatically based on pel symbol attribute, therefore can conveniently, directly any scale adjustment offline
Power circuit is checked in figure.
Wherein, the line in the step S400 includes aerial line segment or cable run.
Further, the pel symbol in the step S300 and S400 and its line are had an independent existence in present offline
In map system level.Therefore unified figure layer can be unified in be managed, such as editor, deletion.
The line attribute that pel symbol corresponds to every level includes color, line style and graphic style, independently corresponds to different layers
Grade, therefore the line attribute of the figure layer can be uniformly modified, it is convenient for Classification Management.
Method provided by the invention is advantageously implemented the account management of power distribution network power equipment, which further includes account number
According to library.Any one pel symbol of power equipment pel symbol database can all generate unique UUID on any level map
Associated object establishes unique association with account data library.It designs the search and management be conducive in database.
The utility model has the advantages that method of the invention effectively improves ground on the basis of retaining original geographical background figure acquisition low cost
Background drawing efficiency is managed, and high-resolution map same as offline map supplier can be provided；Isomorphism constructs professional rack
Figure drafting instrument is greatly improved rack figure and draws efficiency；This method is conducive to system ledger management and search, effectively support distribution
Network service management.

Specific embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of efficient distribution network structure drafting method, comprising the following steps:
S100: building map supply quotient offline map system；
S200: configuration power equipment pel symbol database；
S300: it is plotted in offline map system from particular primitive is selected in pel symbol database；
S400: manual and/or automatic addition line between the pel symbol of adjacent drafting verifies the integrality of connection.
Wherein, the method that S100 constructs map supply quotient offline map system is:
S101: obtaining the offline map picture of map supply quotient, and the n picture of every level is successively stored in n storage catalogue,
Unified picture pixels size；
S102: the total pixel size of splicing picture of every level is obtained, the display of every level is obtained divided by current window pixel size
Scale bar；
S103: the maximum display scale ruler and minimum display scale ruler of all levels are obtained；
