Usually, the exploration that the path of the line of electric force of existing line of electric force or planning is carried out is confined to path, road along the line a bit aiming at another and put the path of following the tracks of line of electric force from the circuit.Traditional method can only be considered local lineament, for example road, house etc. very limitedly.The measurement of being carried out in the line of electric force exploration normally is recorded in the bidimensional coordinate that calculates measuring point in the minute book and after certain hour, height and distance for example along the line by hand.With traditional draughtsmanship these coordinates are drawn then.With this data input computing system, then to import by hand if desired.After this can on this curve map, determine the position of the supporting member that the line of electric force planned is required.Mark lead thereupon and check its distance apart from ground.If obtained enough distances, this design just is accepted and specifies corresponding material so that lay so.
There are following shortcomings in system based on this content.That is:
-whole design process adopts 2-D data and in fact should use three-dimensional data
-when changing the design charges planned and the expense height.
-whole process is very slow.
Mistake appears in the hand computation of input of-data and coordinate and drawing easily.
-prospecting technique requires and will remove fully so that set up a visual field clearly along the woody plant of the corridor in the path of being planned.
-prospecting technique gives no thought to the landform beyond the line route.
-design process is carried out in scale map, rather than with actual ratio, therefore because the landform of being drawn is unclear, may introduce error.
-lead designs with preset parameter.With respect to the various restrictions that will consider, these parameters can not change easily.
-before being accepted, design do not calculate the expense of the circuit of being planned.
Utilize U.K number of patent application 2,230, disclosed line of electric force surveying device and method can overcome above-mentioned shortcoming in 090A and the U.S patent application serial number 07/741114.
The line of electric force program of describing in these patented claims is a kind of program module of special use, it can move in any suitable procedure establishment environment, can be 2202871A for example at number of patent application, be entitled as in the U.K patented claim of " survey data record method and apparatus " and move in the described environment of invention disclosed, this patent documentation hereinafter as a reference.
Disclosed line of electric force survey system is the computer program that a cover is used for overhead power transmission line is carried out Aided Design and maintenance among U.K patented claim 2230090A number and the USSN07/741114.It has covered all aspects of design process, promptly measure the expense and relevant safety standard and industrial guideline of determining accurate supporting member position and wire type, consideration expection, until the required assembling of the stage of setting up to the end and the tension force of inspection circuit etc. from initial landform to the path of being planned.Key character of this cover program is that it is not just to finish after finishing the stage of setting up, but continues the visual inspection that the link tester that has set up is crossed various accessories is carried out the inspection of relevant loss or damage aspect and checked by surveying again when needed.In addition, it is not limited to the circuit that newly sets up, but is similarly the exploration of existing circuit and the supervision of existing supporting member provides convenience, as long as make them enter system at this.All these functions can realize in an independent cover synthesizer and they all quote an independent database.
The field exploration program allows tested line route not only can be on the actual position of circuit self, is other place of object of reference but also can be in away from the path of circuit but with this path.Yet this does not get rid of traditional prospecting technique that the variation that utilizes point obtains suitable height and distance information, but by by this way whole three-dimensional positions of observation station being calculated of present permission it has been done to replenish.A kind of dirigibility is provided in addition, that is, has been provided with the traditional switch technology that directly enters next station transmission three dimensional local information as transform method from a station.
In the open air during the exploration, by using new line of electric force prospecting technique to be easy to establish the position of whole inaccessibility points, this exploration comprises, determines to comprise the vertical plane of required point with two easy approaching points, the required point and calculate its position of directing pointing then.
For the exploration after the existing line of electric force trimming, the field exploration program can still monitor and gained data and design data library information are compared existing supporting member under in the open air the situation at the exploration instrument.
All position datas are all carried out record with the form of three-dimensional coordinate.Can certainly use traditional two dimension output so that be consistent with existing work habit and form.
The survey data of collecting with open-air computing machine can be sent into the design system of building in the office directly or by storage medium.Each data is inserted in the serial data and as the reference point of specific landform.This means that when data are transmitted when passing and arriving office's design system, the reception program will be read this information and with database information it be carried out suitably determining.Thus, reception program has just been set up a data file that is suitable for special purpose computer Aided Design (CAD) system.
The position and the type of supporting member can be added in this design document then.These supporting member information are directly transferred to database from the referral procedure storehouse.This means, can obtain definite size, carrying, structure and the expense of every kind of member at once.
In case established supporting member, just can begin to design lead.For this reason, worked out a specific program, this program has adopted the complex mathematical formula of the determined curve of lead and the position of having drawn lead.The shade of determining the circuit minimum spacing can also be marked, distance to the ground can be checked rapidly thus.Some landform (for example road) need be bigger than this minor increment spacing.These spacings can be checked with the minor increment function as standard that the CAD main system provides by the design engineer.
The lead program comprises various effective lead data and allows the design engineer to select only one.The design engineer can also change equivalent span (and the distance dependent between the point of tension), working temperature, ice coating load and wind condition, checks distance to the ground under extreme conditions thus.
In other stage of design process, check to guarantee that it satisfies all necessary security standards designed circuit, according to required equipment and the expense of being estimated of setting up the cost of designed lines is estimated then.Required equipment can be listed as into a form and use so that order goods in the future.
If in design with will do certain in any time during checking and change, this change can be reflected in the chart that demonstrates rapidly and can promptly check distance to the ground and expense according to safety standard.
The CAD system plotting unit of use standard can at any time obtain to have the hard copy of complete explanatory notes and strict diagrammatic sketch form.
This figure can be given the slip-stick artist who is responsible for work progress.Can lay supporting member on this basis.Can set up lead then.In order to check required tension force whether correctly to apply, also use the open-air counter of hand-held lead is calculated.Can make the slip-stick artist determine lead should how much sagging (considering temperature conditions at that time) like this according to the tension force that is applied.
If need revise landform to adapt to any local geographical change that to set up the area, use same field exploration system just can finish this correction rapidly in the postorder stage.New survey data is delivered to main office and it is overlapped on the prototype, demonstrate any variation that is taken place at once.The effect of these changes can demonstrate moment.Can promptly determine and cost estimation then the change result.
Another feature is, if in some stage, plan (for example changes local geographical situation, build a suitable new road or local household requirement enlarging house), if this change is very important, so the effect of these variations can actual set up beginning before and the construction of line path of being planned done to be determined before the corresponding change.
For the daily servicing of circuit, worked out the circuit inspection program of suitable open-air computing machine, this computing machine can be collected the calibration information that range estimation obtains.In a single day these data are got back to main office and just are added in the database.The point range of not only can be corresponding repairing or further estimating or surveying becomes form, but also can be marked on their position near curve map or the planimetric map so that save the real time in maintenance stage.
At last, can when surveying again, utilize sag and tension force program to check the tension force of circuit then and there.Just can check distance between any point (at the place, ground or at some other highly for example treetop) under the situation that must not observe circuit.Another advantage of this pattern is, not only can check this distance under the common weather condition but also this inspection can also be carried out under the climatic condition in bad luck in the very little place of ground distance.
Provide design for the pole line slip-stick artist and safeguarded all required instruments of pole line under a certain environment in a few cover electric pole circuits that move on the office computer and tower line program, this system is fully open so that the design of having finished enters other the part of inserting its changed information.
Synthesizer moves under main CAD environment, and electric pole circuit/tower line data and figure can transmit need not with dialog procedure and do not produce in the separate unit of loss of information, they have utilized the computing machine that makes same CAD synthesizer operation, and and hardware independent.

Below with reference to accompanying drawings the present invention is further described, wherein:
In order to use during the ground exploration in the open air, several new features in the line of electric force program, have been increased.They are:
1. collimation is determined
2. hillside survey record
3. topographic section
4. tape measure
This four kinds of situations will be described below
1. collimation is determined
Aforesaid field is that each section of circuit considered as the unit that separates with software.At this it is improved, promptly by the drift angle in each break-in of survey record part of path in proper order being connected together becomes a unit.Therefore increased another kind of convenience, promptly utilized equipment to determine initial collimating status with respect to the position of line of electric force, the position of the said equipment is reference substance but not strict being on this path with the path of line of electric force.These system's permission use two cover coordinates or a cover coordinate and quadrant angle and/or surveyor's chain and reference value and horizontal angle are forward determined collimating status.This system is for by observing online point or being object of reference but the not strict point that is on this path determines the quadrant angle of line of electric force that convenience is provided automatically with the line of electric force path.
2. hillside survey record
Referring to Fig. 1, each point that records along the plane of straight line, point is imported a distance vertical with the one or both sides of circuit relatively.Ground the personnel that mark on a map connect together these points, thereby form the topographic section of giving set a distance of center line either side.These sections can be used for determining conductor spacing.
3. topographic section
Referring to Fig. 2, can determine topographic section by measuring intersection point and landform and circuit crossing angle or quadrant angle in landform and center line intersection.Except the survey record angle of intersection, thus can also the survey record center line left side and the difference of elevation of a distance, the right can represent this landform with complete three dimensional form.If survey record is vertical landform, the bottom of this landform and top extend to the both sides of circuit so.
4. tape measure
This measurement has increased convenience, the measured value with tape measure or estimation can be added in the database thus, so that determine that according to previous measuring point they are with respect to circuit distance, difference of elevation and angle.Can measure series of points in this way, each point of determining is all corresponding with a previous point.
Referring now to Fig. 3 and form,, the another set of program that is added in the line of electric force program comprises the module that is used for one or more backguy of electric pole or other wires carry member are enrolled power line design.
For each electric pole that is run into, this program will be determined all circuits, tap portion (fee-offs) and the load of existing backguy on electric pole.This program checks that according to database these parameters see whether it is up to specification.Load surpasses the safe range of regulation, then should select the electric pole of proper strength from routine library.If the situation of electric pole can't be remedied, can under possible situation, determine to use certain guy structure.
Every kind of suitable all possible guy structure of electric pole all is stored in the database file.This document have backguy intensity, allowed minimum/at most backguy numbers, pitch (for backguy to) and the angle of backguy and electric pole.This information stores with decomposition (horizontal and vertical combining) these three kinds of different load-up conditions with horizontal, vertical.
When electric pole needs backguy, from database file, read the guy structure of electric pole in order successively, meet up to one of discovery till the backguy of load-up condition.Provide the figure of these backguys and it is imported the diagram module.Calculate then and be added in the surplus load on the electric pole and when electric pole can not bear this load, provide warning.
In the load out of trim with determined under the situation of existing backguy, this program will be changed (backguy directly influence imbalance and mate forming unbalanced load) to those backguys that has been considered to non-equilibrium loading.
The typical printout result of backguy module when form is illustrated in 13 electric poles measuring line of electric force.For each electric pole, estimate electric pole intensity with this module and whether satisfy the demand.If do not satisfy the demand, then show danger or wrong, at this moment this program will be calculated (referring to for example calculating of electric pole 3) again with the bigger electric pole of intensity.If do not find the electric pole of proper strength, then should increase by at least one backguy in the program.
