Embodiment
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 clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to accompanying drawing 1, the schematic flow sheet of a kind of power circuit method for building up providing for the embodiment of the present invention, the method comprises:
Step S101: the two-dimentional line of electric force data of obtaining the described power circuit being applied on three-dimensional platform.
Step S102: the two-dimentional line of electric force data of described power circuit are converted to three-dimensional data.
Described three-dimensional data comprises a data and line data.
Two-dimentional line of electric force data for the power circuit loading under three-dimensional platform, restriction due to data layout, the two-dimentional line of electric force data of power circuit need to be converted to the form that can load under three-dimensional platform by data converter, then three-dimensional platform reads this three-dimensional data by network mode, finally realizes the three-dimensional display of two-dimentional line of electric force data.
The data layout of supposing to deposit in electric power data storehouse three-dimensional data is DWG form, and first data converter is converted to point-line-surface data by DWG data, and this transfer process can be by being used teigha control to realize.After point-line-surface DSR, being two-dimentional line of electric force data, how realizing on three-dimensional platform and representing, and corresponding dotted line content revealing is become to the form of three-dimensional power model, is the key that three-dimensional data represents.
Step S103: for every bit data, set up three-dimensional line rod model at described some data place, and determine the elevation information between three-dimensional line rod model described in each.
While traversing some data from a data, at first data place, just set up three-dimensional line rod model, from second point data, start except setting up three-dimensional line rod model, also to determine the height with previous some data bus connection, until traverse last some data, the three-dimensional model of simple straight line pattern has just established.
Step S104: for the line data between every two described three-dimensional line rod models, determine two distances between described three-dimensional line rod model, and the difference in height information of two described three-dimensional line rod models, the number that calculates the straight line that forms curve corresponding to described line data according to described distance and described difference in height information, is connected to form curve corresponding to described line data by described number bar straight line.
Be understandable that, circle can be regarded a positive N limit row that is joined and formed by a lot of very short straight-line segment first places as, N is more than or equal to 1 positive integer, curve with radian also can be connected into by a plurality of straight lines, first to determine between two three-dimensional line rod models and will form this arc (number) with how many straight lines, and the falling head (maxdh) of straight line position when two three-dimensional line rod models are middle.
Can calculate two distances (distance) between three-dimensional line rod model by function, then calculate the length (segment=distance/number) of every section of straight line, the height (high=Math.Sin ((3.14159261/number*i)) * maxdh) that obtains the decline of every section of straight line by traversal subtracts the height acquisition z coordinate of decline again with original height.The coordinate figure of x, y, z that has so just obtained the end points of each straight line, is recorded in array, until traveled through number time, then the coordinate of the end points of these each straight lines is generated to line, be exactly curve.
Step S105: for three-dimensional line rod model described in each, calculate the angle of laying of described three-dimensional line rod model.
The three-dimensional line rod model that each some data that power circuit R is corresponding are laid has certain angle, and correct judgement three-dimensional line rod model is laid angle, can avoid the situation that power circuit intersects to occur.Refer to Fig. 2, the schematic diagram of laying angle of a kind of three-dimensional line rod model providing for the embodiment of the present invention.First the angle of laying of determining the three-dimensional line rod model that first data are corresponding is A direction, supposes that the direction of laying of the three-dimensional line rod model that next some data are corresponding is on C and C1 line.Do so B to the second three-dimensional line rod model corresponding to some data of perpendicular line of A, so just generate two angle d1 and d2, the situation of intersecting for fear of power circuit, the angle of laying that can judge three-dimensional line rod model should be in d1 angular range, be less than 180 degree, by that analogy, find to guarantee that the condition of three-dimensional line rod model homonymy is that the angle of laying of all three-dimensional line rod models is less than at the same time 180 degree angles or is greater than on the angular bisector at 180 degree angles simultaneously.So this angle is assigned on the deflection angle attribute of these data.Wherein, the laying angle and can directly draw by function of the three-dimensional line rod model that first data are corresponding, the three-dimensional line rod model that last some data is corresponding lay the angle of laying that angle can equal three-dimensional line rod model corresponding to previous some data.
Can be by function by each on three-dimensional line rod model center line bar, the direction along the arm of three-dimensional line rod model moves to the top of the arm of three-dimensional line rod model, the Position that supposes to set up each point in three-dimensional line rod model center line bar is currWaypoint, the brachium of three-dimensional line rod model is x, by currWaypoint=currWaypoint.Move (x, currWaypoint.Yaw ± 90,0) calculate the point of setting up line, other constant, need to set up several lines the method that just repeats several times, many lines are just established like this.
Step S106: set up described power circuit according to corresponding curve and described each three-dimensional line rod model of line data of laying between angle, described every two described three-dimensional line rod models of three-dimensional line rod model described in each.
