according to plotting position, scene, the geographic satellite layer that coupling system provides and VectorLayer, determine location point, completes cable shaft manual drawing function;
(3) system provides to lay and buries function underground, laid processes safeguards the topological relation with cable shaft automatically, cable burial parameter is selected before drawing, as embedding manner, profile type, bury title underground, distance of embedded pipe, numbering start position, pipe laying ranks number, select whether increase cable shaft, select whether automatic filling cable shaft is numbered, select cable number from increasing from subtracting, embedding manner comprises ditch and buries, pipe buries, crane span structure, water-bed, direct-burried, tunnel, push pipe, built on stilts corridor, profile type comprises regular and irregular section, after drafting, system buries type underground according to what set automatically, pipe laying ranks number creates sectional view automatically,
(4): system provides opens sectional view function, sectional view is buried underground for safeguarding, amendment and creative management unit, service conduit permeability;
(5): system provides manually adds cable signal point function, the cable information of cable locating track is not completed and pore takies situation for typing, in sectional view, by adding cable signal dot pattern, color is used to distinguish type of cable, and use mark records cable title, record cable information with this, this is cable signal point manual creation pattern;
(6): system provides cabling, cable to associate and buries function underground, the cable information of cable locating track has been completed for typing, complete when cabling simultaneously and go out ditch operation into ditch, system creates cable signal dot pattern automatically, and according to the administrative unit of the type of cable selected, electric pressure and selection, Lookup protocol cable signal point color, and the affiliated cable field of maintenance cable signal point is the ID value of this cable, this is the automatic creation mode of cable signal point;
(7): system provides cable shaft profile stretch-out view, centered by work well, all directions section is according to spatial relation automatic placement, automatically the situation of taking is marked and drawed with color according to cable louding, there is provided and check pipeline account informational function fast, in addition, in stretch-out view, support sectional view photo upload function, multiple pictures is uploaded in a cable shaft or a section support.
