According to the order of main chain path, each branch road main chain, the path segments of each segmentation and corner pile are named;
Step S05, generates loop path group navigation scheme;
By defining the terminal of each time line route, the connection according to branch's corner pile generates the several loop path group navigation scheme be made up of path segments;
Step S06, chooses loop path group;
By selecting loop path group navigation scheme, optimize loop path group;
Step S07, determines transmission system rack logical relation, generates loop flat section index, cutting segmented paths sectional drawing, re-writes the flat profile data storehouse of segmentation;
On the basis of the loop path group chosen in step S06, carry out loop attribute definition; Again according to the rack logical relation of path segments in loop path group, carry out the association of branch's corner pile, and generate flat profile data storehouse, loop; Simultaneously go out segmented paths sectional drawing for all path segments after step S04 name, ground elevation cutting, re-write the flat profile data storehouse of segmentation;
Step S08, reconstruct loop path plane cross section;
According to the flat section index in loop, and utilize segmentation flat profile data storehouse virtual reconstruction loop path plane cross section;
Step S09, whether ranking judges;
Judge whether there is the flat section of the segmentation having completed shaft tower ranking in the section combination of loop path plane cross section, entering next step after then calling the segmentation flat section shaft tower database of ranking as existed, if do not existed, directly entering next step;
Step S10, sets up lead wire and earth wire database in circuit pole tower annex and shelves;
By utilizing loop path plane cross section to carry out shaft tower ranking, set up lead wire and earth wire database in circuit pole tower annex and shelves, and ranking results is write segmentation flat section shaft tower database corresponding to the flat section of each segmentation;
Step S11, arranges out several lead wire and earth wire hanging wire mode;
By carrying out hanging wire template definition on three-dimensional shaft tower, utilize lead wire and earth wire database in loop flat section index, segmentation flat profile data storehouse, segmentation flat section shaft tower database, circuit pole tower annex and shelves, according to loop trend, avoid that lead wire and earth wire is intersected, the principle auto arrangement of multiloop negative phase sequence goes out several lead wire and earth wire hanging wire mode;
Step S12, batch is optimized, change lead wire and earth wire hanging wire mode;
Optimize loop, phase sequence hanging wire mode, require to carry out batch optimization, change lead wire and earth wire hanging wire mode according to transformer station interval, loop transposition, wire commutation and special overlap joint, upgrade lead wire and earth wire database in circuit pole tower annex and shelves according to lead wire and earth wire hanging wire mode simultaneously;
Step S13, completes three-dimensional scenic modeling.
