Description

A kind of transmission line forest fire alarm method
Technical field
The invention belongs to electric power project engineering field, be specifically related to a kind of transmission line forest fire alarm method.
Background technology
When there is mountain fire near transmission line of electricity, will spread below it in a few minutes to dozens of minutes, thus cause tripping operation.Therefore, when satellite monitoring is to mountain fire, the alarm that this fire point is formed transmission line of electricity should be calculated rapidly, for the valuable time is striven in the scene measure of putting out a fire to save life and property.But, the transmission line of electricity of each province is intricate, shaft tower is nearly hundreds thousand of to millions of, and in the mountain fire high-incidence season, fire within some province one day is counted just hundreds of, therefore calculates a large amount of fire point and in fact can regard with the distance between magnanimity shaft tower the computational problem that loose point data asks for neighbour as.The method of computing electric power line mountain fire alarm was in the past, carries out search calculate shaft tower one by one, calculated fire point and its distance one by one, carried out alarm according to shaft tower and fire point distance.This method computing velocity is very slow, and only can calculate a fiery point at every turn, easily incurs loss through delay the process opportunity of fire point.
Summary of the invention
The technical problem to be solved in the present invention is, loaded down with trivial details defect is calculated for warning distance between a large amount of fire point of transmission line forest fire and magnanimity shaft tower, propose a kind of transmission line forest fire alarm method, the method energy several times are increased work efficiency, and search speed is fast, calculating accuracy is high.
Technical scheme of the present invention is: a kind of transmission line forest fire alarm method proposed, it is the multiple fiery point coordinate monitored according to polar-orbiting satellite, the circle that radius is 3km is drawn respectively centered by each fire point, buffer zone using this circle as corresponding fire point, search k neighbour's shaft tower in buffer zone, only carrying out alarm calculating to k neighbour's shaft tower place transmission line of electricity can success.The method comprises following concrete steps when performing:
(1) shaft tower geographical basis data, are collected.Online collection entrusts the electric power line pole tower in province to fall apart point set G,
G={a 1(lon 1,lat 1),a 2(lon 2,lat 2),…,a n(lon n,lat n)},
In formula, G is that electric power line pole tower falls apart point set, a nbe that the n-th shaft tower falls apart a little, lon nbe the longitude that the n-th shaft tower falls apart a little, lat nit is the latitude that the n-th shaft tower falls apart a little.
According to above formula, continue the geographical basis data that in collection type, contained each electric power line pole tower falls apart a little, described geographical basis data comprise electric pressure, latitude and longitude coordinates, transmission line of electricity title and, geography information figure layer data, vegetation distribution plan layer data;
(2), fiery dot buffer zone is divided.If satellite monitoring fire point is f i(x i, y i), f in formula ibe i-th satellite monitoring fire point, x ibe i-th satellite monitoring fire point longitude coordinate, y ibe i-th satellite monitoring fire point latitude coordinate, i=1,2,3 ..., with each fire point for the center of circle, with 3km length for radius draws circle respectively, then the region that each circle comprises is the buffer zone of this fire point;
(3), fire point neighbour shaft tower search.Be the electric power line pole tower in each buffer area in the drawn circle of on-line search step (2), fire point f i(x i, y i), f in formula ibe i-th satellite monitoring fire point, x ibe i-th satellite monitoring fire point longitude coordinate, y ibe i-th satellite monitoring fire point latitude coordinate, i=1,2,3, the shaft tower a in buffer zone, place i1, a i2..., a ikbe k neighbour's shaft tower of i-th fire point, see accompanying drawing 1 ~ 2, as shown in Figure 1.If fire point f i(x i, y i) place do not find shaft tower in buffer zone, then can confirm that this fire point is without neighbour's shaft tower, and then confirm that this fire point does not form alarm to transmission line of electricity;
(4) fire point neighbour's shaft tower place transmission line of electricity, is judged.I-th fire point f is judged according to entrusting the electric power line pole tower in the province point set G that falls apart i(x i, y i) all transmission lines of electricity at k neighbour's shaft tower place;
(5), judge that whether passage is unimpeded.Combustible passage between the transmission line of electricity in province and described fire point is entrusted in on-line search.According to transmission line of electricity vegetation distribution layer and the geography information layer in online trust province of collecting, judge that whether the combustible passage searched between described fire point and described transmission line of electricity is unimpeded according to following regular A ~ B.Described regular A ~ B is:

If rule D is D≤1km, issue described fire point to the information of entrusting transmission line of electricity to form Level 1Alarming;
If rule E is 1km<D≤2km, issue described fire point to the information of entrusting transmission line of electricity to form secondary alarm;
If rule F is 2km<D≤3km, then issue described fire point to the information of entrusting transmission line of electricity to form three grades of alarms.
The experience of trial edition method alarm transmission line forest fire shows, the shaft tower beyond distance fire point 3km can not be dangerous, therefore only need carry out alarm calculating to the shaft tower that fire is put within 3km scope.Problem reduction is: find k neighbour's shaft tower within the scope of single fire point 3km, only needs to calculate the distance between fire point and k neighbour's shaft tower.Compared with ergodic algorithm in the past, avoid the calculating to the outer a large amount of shaft tower of scope, substantially increase work efficiency, also can carry out alarm calculating to multiple fire point simultaneously, avoid waiting in line of multiple fire point, hundreds of times of ground improve computing velocity, substantially reduce the fire point processing time.
The invention has the beneficial effects as follows:
1), this method orderliness is clear, and computing velocity is fast, efficiency is high, and the transmission line forest fire alarm being applicable to any area calculates;
2) search to the overseas shaft tower in fiery dot buffer zone, can being avoided, apart from calculating, significantly improving computing velocity;
3), alarm calculating can be carried out to multiple fire point simultaneously, substantially increase counting yield;
4), make full use of vegetation distribution plan layer data, consider that whether the combustible passage between fire point and transmission line of electricity is unimpeded, avoid and issue fault alarm information to without dangerous fire point, improve the accuracy of alarm;
5), alarm is carried out according to the distance of fire point and transmission line wire, compared with the mode of in the past carrying out alarm according to fire point and shaft tower distance, more tally with the actual situation, and avoid the warning information multiple shaft towers of same transmission line of electricity being issued to repetition.
