Description of the drawings
Fig. 1 is a kind of three-dimensional power transmission line corridor band design method flow chart based on GIS provided by the invention.
Specific implementation mode
The specific implementation mode of the present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of three-dimensional power transmission line corridor band design method detailed process based on GIS of the present invention is as follows：
(1) new route engineering：
According to military area, waters protection zone, airport control zone, nature reserve area, scenic spot, minery, planning region, danger
Product area, geological-hazard-prone area, important scissors crossing etc., the Compulsory Feature that owner is added form important evacuation region, import
Primary spatial data can be in path each intersecting point piling position during on-site land survey after selecting path in engineering, and utilizes
GPS device records stake position longitude and latitude, elevation coordinate, in three-dimensional scenic, can import each stake position GPS data in GIS,
Three-dimensional scenic shows each stake point.After selecting each stake point, tower is selected, i.e., selected tower is conducive to this point, is established after layout
Line project figure.
(2) in circuit engineering drawing neutrality tower；
Wherein, including refer to the vertical tower of fixed pile, the vertical tower of span, Manual vertical tower and the ranking of strain section Automatic Optimal is specified to found tower.
1, refer to fixed pile and found tower：
Stake position is read from GIS Path selection results, turriform is inputted, selected turriform is stood on into finger fixed pile.
2, the vertical tower of span (tired away from) is specified：
Line route (tower point can not be found by having been deleted in line route, similarly hereinafter) is read from GIS Path selection results, inputs base
Quasi- tower number, span (tired away from), turriform, specified span position is stood on along line route by selected turriform.
3, Manual vertical tower：
Line route is read from GIS Path selection results, inputs turriform, mouse selects position, if the position is not in circuit
In path, angle tower can only be found, and change line route, selected turriform, which is stood on mouse, selects position.
4, tower is found in strain section Automatic Optimal ranking：
Assuming that possible vertical tower point has N number of on one section of circuit, stand the starting of tower point marked as 1, terminal marked as N, ranking
Tower has M kinds, various towers to have K kind tower heights.
The step of using labeling method to optimize ranking for：
A, the variant content of label point is determined；
B, the variate-value of each label point is sequentially calculated；
C, optimum results are searched out according to the variate-value backward of each label point.
It is specific as follows：
The direction of travel of configuration optimization is carried out from label point 1 to label point N substeps, and one will be carried out in each label point
Suboptimization.In order to record and transmit the optimum results of each label point it is necessary to determine the variant content of label point, to record mark
The state of number point, step-by-step optimization as a result, preparing data for optimization in next step.The main contents of label point variable in configuration optimization
There are 8：Label piont mark, the tower height of label point, the optimal connection of rear side the optimal connection of label piont mark, rear side tower, after
The tower height of the optimal connection in side, the accumulation economic indicator of optimal connection, label point rear side horizontal span, the vertical shelves of label point rear side
Away from.The content of label point variable can also increase rear side and optimize the parameters such as the drop base unit weight of connection label point, insulator chain pattern
To record the result of step-by-step optimization in further detail.
When current index point carries out step-by-step optimization and tower height takes different value, the result of optimization generally also differs, should
The tower height of label point is also that can not can determine that in step-by-step optimization, therefore, the above variable more than 1 for each label point
Group, how many kind tower height, label point is with regard to how many group variable to record optimum results when different tower heights.
The variate-value for calculating each label point is the process of multi-scheme ranking and step-by-step optimization.Calculate each label point variate-value
Direction of travel from label 1 to label N, gradually the ranking scheme of each label point is compared, records each tower of label point
Optimal case result when high.
Calculate label point variable method be：One timing of tower height of label point, is connected with each label point below taps into respectively
Row ranking, at this moment the parameters such as the tower of back label point, insulator chain pattern and economic indicator just can determine that.To all ranking sides
Case carry out accumulation economic indicator relatively and using the result of optimal case as the variate-value of label point.
The variate-value of label point 2 is calculated first.It determines that the tower height of label point 2 is H, label point 2 is connected with label point 1
Ranked, take various towers, tower height to rank respectively label point 1, while being verified to every ranking content, not at
Vertical scheme is given up.Since the tower of label point 1, tower height are to determine, tower material index, foundation cost, insulator chain
Expense etc. also determines therewith, thus obtains economic indicator when label point 1 takes different towers, tower height.To the ranking side of establishment
Case carries out Economic contrast, the variate-value using the minimum scenario outcomes of economic indicator as label point 2 in tower height H.Change label
The tower height of point 2 repeats above procedure, thus obtains the variable that label point 2 is connected in each tower height with label point 1
Value.Calculate the variate-value of label point i.It determines that the tower height of label point i is H, label point i is connected with 1~i-1 of label point respectively
It connects, and takes various towers, tower height to be ranked and verified respectively in 1~i-1 of label point, invalid scheme is given up.Work as label
When point i is connected with label point j, because i points and the tower height of j points have been determined, the level, vertical span on front side of j points are also certain,
Level, vertical span on rear side of j points in j point variables by learning.The economic indicator of each scheme is accumulated value, i.e., will be with label point
Economic indicator in the label point j variables that i is connected is plus the label point j economic indicators of itself.To the ranking side of all establishments
Case carries out Economic contrast, will accumulate variate-value of the minimum scenario outcomes of economic indicator as label point i in tower height H.Change
The tower height of label point i repeats above procedure, thus obtains variate-values of the label i in each tower height.
After the variate-value of each label point calculates, optimum results can be easily searched out.Find optimum results
Process be backward, i.e., from label point N to 1 recursion of label point.The accumulation economy under each tower height to ranking terminal label point N
Index is compared, and economic indicator the lowest is prioritization scheme.According to the optimal linkage record of rear side in prioritization scheme variable
Label, tower, the tower height that the optimal connection label point of the rear side being connected with the prioritization scheme of label point N can be found, are passed successively
It pushes away until tower, tower height of the recursion to label point.A deck label point, tower, the tower height that the above contrary recurrence is found out are whole section
The result of line optimization ranking.If before ranking, tower, the tower height of beginning or end it has been determined that its optimization process
With it is above-mentioned still consistent, only the set of variables of beginning or end only has one group.
The basic thought of Dynamic Programming is that optimization problem is divided into several stages, then carries out subsection optimization to reach whole
Body optimizes.According to this thought, it is desirable that the model of optimization has markov property.So-called markov property is exactly model with following
Feature：The past situation of process can only go the future of influence process by current state.That is, if given a certain
The state in stage, then each stage condition is not influenced before by this stage for the development of process later in this stage.
Tower is integrated and is determined by the level of front and rear sides, vertical span on tower position.But in above-mentioned configuration optimization process
When the tower of middle determining label point i, the tower of rear side, the level of tower height and rear side, vertical span are all certain, optimization
Ranking only considered the variation of front side, and therefore, the result of optimization may be not achieved optimal.For example, the tower height as label point i is
When 27m, optimal connection label point is i-1, tower G1-27 on rear side of the result of label point i step-by-step optimizations is.
Step-by-step optimization is carried out in label point i+1 in next step, is attached simultaneously with i points when the tower height of label point i+1 takes 27m
Determining tower when label point i tower height 27m, the tower that vertical span is more than G1 tower use condition 5m, i points at this time is G2-27, this
It is G2-27 that sample, which in the result of i+1 point step-by-step optimizations is i point towers, and i-1 point towers are G1-27.If but changing the tower of i-1 points
Height uses G1-30 in i-1 points, then the vertical span of i points will reduce, and G1-27 can be used.Obviously, it is used in i-1 and i points
The tower material index of the tower material index ratio G1-27 and G2-27 of G1-30 and G1-27 is small, i.e., this optimum results is more preferable.This example is said
It is illustrated when i+1 points carry out step-by-step optimization, the tower height variation of i-1 points still has influence to optimum results, while illustrating
Stating configuration optimization process, there are aftereffect to ask influence, while illustrating above-mentioned configuration optimization process there are aftereffect sex chromosome mosaicism, is discontented with
The result of the condition of the sufficient thoery of dynamic programming, optimization is not optimal result.
The aftereffect sex chromosome mosaicism of configuration optimization is solved, the group number of label point variable only need to be suitably increased, aftereffect will be generated
Factor also record and later optimization process be added.When label point takes a tower height to optimize and compares, more than remember
Record one accumulation economic indicator minimum optimum results, but to rear side each difference tower height when optimum results will record
Come.If there is K kind tower heights, the set of variables number of label point increases to K2 groups by K groups.To solve the aftereffect sex chromosome mosaicism of configuration optimization,
The variate-value of label point i should be calculated by the following method.Determine label point i tower height be H, by label point i respectively with label point 1~
I-1 is connected, and takes various towers, tower height to be ranked and verified in 1~i-1 of label point, ranking when should by label point 1~
The various tower height schemes of the optimal connection of rear side take into account in i-1 variables, and invalid scheme is given up.To the scheme of all establishments
Compare by the different economic indicator accumulated of tower height grouping of rear side, using the minimum scenario outcomes of economic indicator in each group as
Label point i in tower height H on rear side of various tower heights variate-value.Change the tower height of label point i, repeats above procedure, this
Sample just obtains label point i in various tower heights, and rear side connects the variate-value in the case of different tower heights.Above-mentioned optimization method solves
The aftereffect sex chromosome mosaicism of configuration optimization meets Dynamic Programming markov property requirement, to make being optimal of ranking results.
