Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and
It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.
Refer to accompanying drawing 1, for the flow process signal of a kind of power circuit method for building up that the embodiment of the present invention provides
Figure, the method includes:
Step S101: obtain the two-dimentional power line data of the described power circuit being applied on three-dimensional platform.
Step S102: the two-dimentional power line data of described power circuit is converted to three-dimensional data.
Described three-dimensional data includes point data and line data.
The two-dimentional power line data of the power circuit for loading under three-dimensional platform, due to data form
Limiting, the two-dimentional power line data of power circuit needs to be converted to by data converter can under three-dimensional platform
The form loaded, then three-dimensional platform reads this three-dimensional data by network mode, final realization two dimension electricity
The three-dimensional display of line of force data.
Assuming that the data form depositing three-dimensional data in electric power data storehouse is DWG form, data converter is first
First DWG data being converted to point-line-surface data, this transformation process can be by using teigha control real
Existing.After point-line-surface DSR, it is two dimension power line data, how to realize opening up on three-dimensional platform
Existing, and by the form of the corresponding three-dimensional power model of dotted line content revealing one-tenth, be that three-dimensional data represents
Crucial.
Step S103: for every bit data, sets up three-dimensional line rod model at described point data, and
Determine the elevation information between each described three-dimensional line rod model.
When point data traverses point data, at first point data, just set up three-dimensional line rod model, from
Second point data start in addition to setting up three-dimensional line rod model, are also predefined and the height of previous point data line
Degree, until traversing last point data, the threedimensional model of simple straight line pattern just establishes.
Step S104: for line data between three-dimensional line rod model described in each two, determine two institutes
State the distance between three-dimensional line rod model, and the difference in height information of two described three-dimensional line rod models, root
The straight line of curve corresponding to the described line data of formation is calculated according to described distance and described difference in height information
Number, connects described number bar straight line and forms the curve that described line data are corresponding.
Connect formed it is understood that circle can be regarded as by a lot of straightway first places the shortest
Positive N limit row, N is the positive integer more than or equal to 1, and the curve of band radian can also be connected by multiple straight lines
Become, first have to determine between two three-dimensional line rod models and form this arc with a how many straight line
(number), and straight line in the middle of two three-dimensional line rod models time position falling head (maxdh).
The distance (distance) between two three-dimensional line rod models can be calculated by function, then calculate
The length (segment=distance/number) of every section of straight line, obtains the decline of every section of straight line by traversal
Height (high=Math.Sin ((3.14159261/number*i)) * maxdh) subtract with original height again
The height declined obtains z coordinate.Thus obtain the coordinate figure of the x, y, z of the end points of each straight line,
Record is in array, until having traveled through number time, then the Coordinate generation the end points of these each straight lines
Line, it is simply that curve.
Step S105: for each described three-dimensional line rod model, calculate laying of described three-dimensional line rod model
Angle.
The three-dimensional line rod model that each point data corresponding for power circuit R is laid has certain angle, just
True judgement three-dimensional line rod model lays angle, and the situation that power circuit can be avoided to intersect occurs.Please join

The angle of laying determining three-dimensional line rod model corresponding to first point data is A direction, it is assumed that next point
The direction of laying of the three-dimensional line rod model that data are corresponding is on C and C1 line.So it is the vertical line B of A
To the three-dimensional line rod model that second point data is corresponding, thus generate two angle d1 and d2, in order to avoid
The situation that power circuit intersects, it can be determined that the angle of laying going out three-dimensional line rod model should be at d1 angle model
In enclosing, less than 180 degree, by that analogy, find that the condition ensureing three-dimensional line rod model homonymy is, all
The angle of laying of three-dimensional line rod model is less than 180 degree of angles or the angle bisection at simultaneously greater than 180 degree of angles at the same time
On line.So this angle is assigned on the deflection angle attribute of this point data.Wherein, count for first
Laying angle and can directly be drawn by function according to corresponding three-dimensional line rod model, last point data
Corresponding three-dimensional line rod model lay the three-dimensional line rod model that angle can be corresponding equal to previous point data
Lay angle.
Can by function by each on three-dimensional line rod model center line bar along the arm of three-dimensional line rod model
Direction move to the top of arm of three-dimensional line rod model, it is assumed that set up in three-dimensional line rod model center line bar
The Position of each point is currWaypoint, and the brachium of three-dimensional line rod model is x, passes through
CurrWaypoint=currWaypoint.Move (x, currWaypoint.Yaw ± 90,0) calculate and set up line
Point, other constant, need to set up several lines and just repeat several times the method, the most a plurality of line is just established.
Step S106: lay described in angle, described each two three according to each described three-dimensional line rod model
Tie up curve corresponding to the line data between line rod model and described each three-dimensional line rod model sets up described electricity
Line of force road.
