Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Embodiment 1
The embodiment of the present invention proposes a kind of section cable position for being applied to cable laying and postpones method, referring to Fig. 1, should
Method includes：
Step 101：Obtain every section and lay channel branch with every corresponding relation for laying path of cable；
Step 102：Every section of type and size for laying channel branch is obtained, and structure lays the disconnected of channel branch according to this
Face, the section should reflect this section lay channel branch and every cable lay path the corresponding relation (including
All processes can be represented, and this lays the cable of channel branch and represents its trend)；
Step 103：After the cable position in the section is adjusted, the section that mark is adjusted is reference section, mark
The cable that note is adjusted is cable to be adjusted；
Step 104：Cable to be adjusted in for non-reference section, finds non-with this in the section that this bar cable is passed through
The closest reference section of reference section upstream and downstream, and this is adjusted according to the cable position of this bar cable in the reference section
Cable position of the cable in the non-reference section.
The application scenarios to the embodiment of the present invention make a simple introduction below：In cabling process, every cable is all
Have it is respective lay path, and every is laid path and can be arranged on certain type of passage (such as cable duct, crane span structure, row
Pipe or direct-burried passage etc.) in.
Thus in order to describe the relation of every cable and place passage, passage will be integrally laid here be divided into some sections and lay
Channel branch, and every is treated that cabling all can lay channel branch through some sections, and each lays channel branch and is respectively provided with
The channel type uniquely fixed.Lead to multiple it is of course possible to can occur one on the position of passage fork and lay channel branch
Lay the situation of channel branch.
So as to lay position in order to set each local cable, it is thus necessary to determine that every cable with lay the right of channel branch
Should be related to, it can be realized by the operation of step 101.Under known determination model, all channel branch of laying are with every
The corresponding relation for treating cabling can be directly to know, simply may difference on expression-form.
Herein, this corresponding relation is expressed preferably in the way of node serial number here：First lay logical corresponding to all
The two ends of road branch are set up node and are numbered, then take the numbered sequence of the node that every cable is passed through as the correspondence pass
System.That is, node is located at lays channel branch two ends, a location point on cable run is represented.By cable road
Footpath is successively to all node serial numbers for laying channel branch two ends, such as " A1 ", " A2 " ... " An ".Laid because node is located at
Channel branch two ends, its starting point and ending point and branch point for just representing cable people having a common goal, the order of node serial number is represented
Branch direction, the representation of cable trace is node serial number sequence.If a cable is sequentially passed through since its starting point
" A1 " and " A2 ", then only number during " A1-A2 " appear in the node serial number sequence of the cable, therefore according to this numbering
Rule can distinguish the cable direction laid in channel branch.This node serial number mode can easily represent every section and lay
Channel branch and every corresponding relation of cable, with very strong operability and practicality.
Step 102 is mainly the section extracted from channel branch is laid in structure.Generally, it is from laying passage
Being chosen in branch can reflect that this section lays channel branch and cut with every one of the corresponding relation for laying path of cable
Face with this lays the type and size of channel branch and limits the specific object of the section as section.It is specifically excellent with one kind
As a example by the construction step of choosing：Channel branch is laid for every section, from the passage including cable duct, crane span structure, comb and direct-burried passage
Determine that this section lays the affiliated type of channel branch in type；The affiliated type for laying channel branch according to this section builds unconstrained
The section of dimension of picture；The size that this section lays channel branch is obtained, and according to this in the section base of the unconstrained dimension of picture
The section for constraining dimension of picture is built on plinth.Referring to Fig. 2 (a), Fig. 2 (b), Fig. 2 (c) and Fig. 2 (d), which respectively show electricity
Cable ditch (Fig. 2 (a)), crane span structure (Fig. 2 (b)), comb (Fig. 2 (c)), the general shape of direct-burried passage (Fig. 2 (d)) and cable can be placed
Region.Such as, after it is determined that laying type described in channel branch for cable duct, just according to the shape as shown in Fig. 2 (a)
The section of unconstrained dimension of picture (every dimensional parameters of each geometric element) is built, channel branch is laid according still further to this section
Under size (such as specific size of cable duct, the depth and width of channel branch) determines the dimension of picture everywhere in section
Come, to form specific section figure.This preferred construction step is by setting up the section shape library corresponding to channel type
To simplify the building process of section, be conducive to the lifting of section building process efficiency.
Certainly, lay and support be also possible that in channel branch, for different types of section, the boundary shape of section and
The region that cable can be placed all is different.As being exactly there was only in pipe that cable can be placed in comb, and in standoff feelings
All it is that cable may be placed only on support under condition.
After the completion of section structure, laying path and lay the corresponding relation of channel branch, every according to every cable
Cable all just also can all specify that by which section, just can be enterprising in these sections hence for every laying for cable
OK, wherein also including setting a plurality of cable of arrangement by adjusting cable position of the cable on each section, determining that its is relative
Position relationship.
Step 103 is mainly cable position and postpones preparatory stage of calculating.When the cable position in the section is adjusted
Afterwards, the section that mark is adjusted is reference section, marks the cable being adjusted to be cable to be adjusted, thus follow-up cable position
Adjustment is just primarily directed to the cable to be adjusted in non-reference section, and reference section had been adjusted so need not be again
Adjustment, non-cable to be adjusted need not do larger change so not making cable position adjustment if there is no need.Specifically, exist
Just it is cable to be adjusted this several cable marks, this after the cable position of a few cables in certain section is changed
Individual section mark is reference section.Preferably carry out cable position postpone calculating before, every cable to be adjusted is passed through
Non-reference section add section set to be adjusted, so as to afterwards just only line position need to be entered to the section in section set to be adjusted
Put adjustment.Certainly, after all steps are completed every time, it is necessary to section set to be adjusted is emptied, to carry out cable next time
Position adjustment.Such step can be substantially reduced the scope of cross section regulation, improve algorithm execution speed.
After above-mentioned mark is completed, step 104 is exactly actually the tune that cable position is carried out on each non-reference section
It is whole.Specifically, seek to first to find upper and lower with the non-reference section in the section for needing the cable to be adjusted of adjustment to be passed through
The closest reference section of trip, to obtain corresponding reference cable position, then adjusts further according to this reference cable position
Cable position in the whole non-reference section.Preferred adjustment mode is as described below：When each section is adjusted, this is first obtained
In reference section the cable position of this cable relative to the position coordinates of section reference point as reference position coordinate, wherein,
The section reference point is on the axis for laying channel branch.The following cable placed in the non-reference section
Region in, the cable position of this cable is adjusted to most short with the position coordinates distance relative to section reference point
Position.Such as, cable duct selects the support nearest away from reference cable position, and crane span structure selection bottom is nearest away from reference cable position
The cable placed room, comb selects the pore nearest away from reference cable position, and direct-burried channel selecting is away from reference cable position
The room of nearest placement cable.Finally, in section all cables all by after above-mentioned adjustment, one being entered according still further to constraints
The cable position of every cable in the successive step non-reference section, the constraints includes：Cable bottom has support to support；
Every cable is not Chong Die with other cables.Generally be exactly will overlap cable separate, under the cable supported without support
Move on to channel bottom.Such adjustment mode is more direct, easy, can soon complete the adjustment of all sections, also
The calculating that cable position in other sections is postponed is quickly finished with according to the cable arrangement in the reference section set by user.
Specific initialization adjustment cable position examples of interfaces as shown in figure 3, user can select any one section, initially
The position of cable is set or adjusted on the original basis, the suitable of cable position on other non-reference sections is carried out on this basis
Prolong calculating, it is possible to be automatically completed the adjust automatically to cable position.Because the cable position in each section is determined, its
Between cable run in channel branch also determine that, lay mould such that it is able to update a whole set of cable on original model
Type, completes the automatic calculating of postponing to the section cable position of cable laying.
The section cable position that what the embodiment of the present invention was proposed be applied to cable laying is postponed method low cost, time
Short, efficiency high, the degree of accuracy are high, substantially increase the automaticity of cable laying flow, can meet more users for electricity
Cable lays the performance requirement of aid.
