Abstract
The present invention relates to a kind of metro safety protection zone illegal item area method for fast measuring.Mainly solve existing manual measurement method and exist time-consuming many, accuracy is poor, the technical problem more than carrying instrument.Method for fast measuring of the present invention is comprised the following steps：Polygon illegal item angle point is gathered：By the gps coordinate of each point of built-in GPS location illegal item profile；Obtain area：Polygon is resolved into into triangular structure, the area of each triangle and the as area of polygon illegal item, wherein：△ opkpk+1 are definition origin,（0,0）For starting point o of triangle, the triangle opkpk+1 of 2 points of pk of polygon arbitrary neighborhood, pk+1 composition, k are polygonal k-th summit, and S is summation；Automatic reference area value is programmed by JAVA again.
Description
Technical field
The present invention relates to a kind of measuring method of project area, more particularly to a kind of metro safety protection zone illegal item face
Product method for fast measuring.
Background technology
In existing metro safety protection zone, the main method of illegal item area measurement is to introduce ordinary skill measuring and calculating at present
Method, for the illegal item of small area, patrolman can be carried out simply by using modes such as tape measure, artificial range estimation estimations
Measuring and calculating, for large area illegal item, patrolman can calculate its area value by the high precision instruments such as total powerstation auxiliary.So
And, with rail line increase and protective zone in illegal item accumulate, existing e measurement technology at present
The requirement that illegal item area is quickly calculated cannot much be met, both time-consuming many, its accuracy is also not high enough, often also needs to
Carry various measurement measuring and calculating instruments to accompany with instrument, both not readily portable, its work efficiency is also very low.
The content of the invention
It is an object of the invention to provide a kind of metro safety protection zone illegal item area method for fast measuring.Mainly solve
Existing manual measurement method presence is time-consuming more, and accuracy is poor, the technical problem more than carrying instrument.
Technical scheme：A kind of metro safety protection zone illegal item area method for fast measuring, including it is following
Step：
A, the collection of polygon illegal item angle point：By the gps coordinate of each point of built-in GPS location illegal item profile；
B, the area for obtaining polygon illegal item：Polygon is resolved into into triangular structure, the area of each triangle and i.e.
For the area of polygon illegal item,
Wherein：△ opkpk+1 are definition origin,（0,0）For starting point o of triangle, polygon arbitrary neighborhood 2 points of pk, pk+1
The triangle opkpk+1 of composition, k are polygonal k-th summit, and S is summation；
C and then automatic reference area value is programmed by JAVA.
The invention has the beneficial effects as follows：The present invention positions illegal item framework by geographical position coordinates, improves artificial
Because of Area computing error caused by time or uncertainty during inspection, the accuracy of area achievement value is further increased.
In terms of work efficiency：During eliminating existing inspection, patrolman need to be caused with reference to calculating by the way of various measuring and calculating
Waste of time, further increase work efficiency.Operationally：Only need to patrolman's understanding and be familiar with illegal item angle
The acquisition operations of point, Area computing are calculated automatically by JAVA programmings, and compared with the prior art, it is more convenient to operate.

1 triangle illegal item coordinate diagram of Fig. 1 embodiment of the present invention.
2 hexagon illegal item coordinate diagram of Fig. 2 embodiment of the present invention.
3 tetragon illegal item coordinate diagram of Fig. 3 embodiment of the present invention.
Fig. 4 illegal item area measurement flow charts of the present invention.
Specific embodiment
Embodiment 1, reference picture Isosorbide-5-Nitrae, each profile angle first by built-in GPS location function, to illegal item
Point is acquired, by high precision instrument aiding in carrying out each angle point positioning and the acquisition of coordinate in gatherer process, most
Area is measured by JAVA programmings afterwards.Specially find that illegal item is triangle, gather illegal item profile first
Gps coordinate S (the x of three points1,y1),a(x2,y2),b(x3,y3), the directed area formula of the illegal item is：
Determinantal expansion in step one can be obtained：
Then automatic reference area value is programmed by JAVA.
Embodiment 2, reference Fig. 2,4, each profile angle first by built-in GPS location function, to illegal item
Point is acquired, by high precision instrument aiding in carrying out each angle point positioning and the acquisition of coordinate in gatherer process, most
Area is measured by JAVA programmings afterwards.Specially find that illegal item is hexagon, gather illegal item profile first
The gps coordinate of six points, with S points as starting point（Point 1）, conduct puts 2,3,4,5,6 to a～e points successively, and the coordinate of six points is：S
(x1,y1),a(x2,y2),b(x3,y3), c (x4,y4), d (x5, y5), e (x6,y6), we can draw following area of a polygon
Summation formula：
So as to derive
Then automatic reference area value is programmed by JAVA.
Embodiment 3, reference Fig. 3,4, each profile angle first by built-in GPS location function, to illegal item
Point is acquired, by high precision instrument aiding in carrying out each angle point positioning and the acquisition of coordinate in gatherer process, most
Area is measured by JAVA programmings afterwards.Specially find that illegal item is tetragon, gather illegal item profile first
The gps coordinate of four points, with S points as starting point（Point 1）, conduct puts 2,3,4 to a～c points successively, and the coordinate of four points is：S(x1,
y1),a(x2,y2),b(x3,y3), c (x4,y4), can obtain：
Note：If being given clockwise, then directed area is negative to point, is given counterclockwise, then directed area is for just.
Therefore, can derive area formula is
So as to derive
Then automatic reference area value is programmed by JAVA.
