Step S05, generates loop path group navigation scheme；
By defining the terminal of each time line route, generated according to the connection of branch's corner pile several by path segments
The loop path group navigation scheme of composition；
Step S06, chooses loop path group；
By selecting loop path group navigation scheme, preferably go out loop path group；
Step S07, determines transmission system rack logical relation, the flat section index in generation loop, cutting segmented paths sectional drawing, again
The new flat profile data storehouse of write-in segmentation；
On the basis of the loop path group that step S06 has chosen, loop attribute definition is carried out；Further according to loop path group Road
The rack logical relation of footpath fragment, carries out the association of branch's corner pile, and generates the flat profile data storehouse in loop；Simultaneously for step
All path segments, corner pile cutting after S04 names go out segmented paths sectional drawing, re-write the flat profile data of segmentation
Storehouse；
Step S08, reconstructs loop path plane cross section；
According to the flat section index in loop, and utilization is segmented flat profile data storehouse virtual reconstruction loop path plane cross section；
Step S09, if ranking judges；
Judge in the section combination of loop path plane cross section with the presence or absence of the flat section of segmentation for having completed shaft tower ranking, such as exist
Then call and enter next step after the flat section shaft tower database of the segmentation ranked, as being directly entered next step in the absence of if；
Step S10, sets up ground wire database in circuit pole tower annex and shelves；
Shaft tower ranking is carried out by using loop path plane cross section, ground wire database in circuit pole tower annex and shelves is set up,
And ranking results are write into the corresponding flat section shaft tower database of segmentation of each flat section of segmentation；
Step S11, arranges out several ground wire hanging wire mode；
By carrying out hanging wire template definition on three-dimensional shaft tower, using the flat section index in loop, flat profile data storehouse, segmentation are segmented
Ground wire database in flat section shaft tower database, circuit pole tower annex and shelves, moved towards according to loop, avoid ground wire from intersecting,
The principle auto arrangement of multiloop negative phase sequence goes out several ground wire hanging wire mode；
Step S12, batch optimization, replacing ground wire hanging wire mode；
It is preferred that go out loop, phase sequence hanging wire mode, according to transformer station interval, loop transposition, wire commutation and special overlap joint require into
The optimization of row batch, replacing ground wire hanging wire mode, lead while being updated according to ground wire hanging wire mode in circuit pole tower annex and shelves
Ground wire database；
Step S13, completes three-dimensional scenic modeling.
