In order to more clearly illustrate technical scheme and advantage, below to a kind of Statistical Area provided by the invention
The method of device within the domain quantity is described in detail, as shown in Fig. 2 specifically may comprise steps of：
Step 201：The coordinate points of each point device and at least one coordinate points of each tube apparatus are prestored, wherein
Each tube apparatus and each point device carry different types of identification information.
Specifically, each point device or tube apparatus have its corresponding coordinate points when being placed into working region, and pipe is set
The standby coordinate points that can have corresponding two end points, and when tube apparatus often increases a flex point, tube apparatus can increase by one and turn
Point coordinates point, and tube apparatus and point device carry different types of identification information, and coordinate points corresponding to each equipment
Coordinates logo information corresponding to carrying, it needs to be determined that area's device within the domain to be counted quantity when, can be according to each coordinate points
The type of coordinates logo information determine the quantity of area's device within the domain to be counted.
For example, prestore and sat corresponding to coordinate points s corresponding to point device S, coordinates logo information ss, point device D
Punctuate d, coordinates logo information dd, coordinate points g1, coordinates logo information gg, coordinate points g2 and coordinates logo corresponding to tube apparatus G
Information gg.
Step 202：Obtain the coordinate points of each point device for not determining corresponding region that prestore and each do not determine
At least one coordinate points on the tube apparatus of corresponding region.
Specifically, when obtaining the coordinate points and identification information of each point device and each tube apparatus, it is necessary to first really
Whether fixed each equipment has determined corresponding region, and and if only if at the equipment not region corresponding to determination, can obtain
Coordinate points corresponding to the equipment and coordinates logo information.
For example, in point device S, point device D and tube apparatus G, point device S has determined that corresponding region is H, so
What acquisition prestored does not determine that coordinate points d corresponding to the point device D of corresponding region, coordinates logo information dd, tube apparatus G are corresponding
Coordinate points g1, coordinates logo information gg, coordinate points g2 and coordinates logo information gg.
Step 203：It is determined that the border that each head and the tail for forming region to be counted are sequentially connected with.
Specifically, it is described corresponding according to the region because each region by least three is that line section boundary forms
Each border two end points coordinate, it may be determined that the position in region to be counted.
For distance, region Y to be counted border b1, border b2 and border b3 are determined.
Step 204：For each coordinate points, changing coordinates point is judged whether on any one border, if it is, holding
Row step 213, otherwise perform step 205.
Specifically, when judging that each coordinate points are whether in region to be counted, it is necessary to first by the coordinate points with it is to be counted
Each border contrast in region, it is determined whether on border, if, it may be determined that the coordinate points are in region to be counted, such as
Fruit does not exist, and ray is done by end points of the coordinate points, judges whether with the number of the intersection point on the border in region to be counted be odd number, such as
Fruit is that odd number can determine that the coordinate points in region to be counted, otherwise, it determines the coordinate points are outside region to be counted.
For example, judge coordinate points d, coordinate points g1 and coordinate points g2 whether on border b1, border b2 and border respectively
On b3, if coordinate points d on the b1 of border, can determine coordinate points d in region Y to be counted.Coordinate points g1 is in border b2
On, then it can determine coordinate points g1 in region Y to be counted.Coordinate points g2 is not on either boundary, using coordinate points g2 as end points
It is the ray g2 parallel to X-axis.
Step 205：It is determined that using changing coordinates point as the ray of end points.
Specifically, in changing coordinates point not when on the either boundary in region to be counted, then using changing coordinates point as end points
Ray is done, the ray can be parallel to X-axis, any one ray parallel to Y-axis or known angle.
Step 206：Judge that ray whether there is intersection point with each border, if it is, performing step 207, otherwise perform step
Rapid 215.
Specifically, because ray is without line length, it is possible to whether intersection point with each border is had to judge according to ray, when
Whether preceding coordinate points are in region to be counted.
For example, judge that ray g2 whether there is intersection point with border b1, b2 and b3 respectively；
If there is no intersection point in ray g2 with any one border, it may be determined that coordinate points g2 is outside region Y to be counted；
If any one or more in ray g2 and border b1, b2 and b3 have intersection point, need according to each friendship
Whether point judges coordinate points g2 in region Y to be counted.
Step 207：Judge with the presence or absence of the end points of either boundary in each intersection point, if it is, performing step 208, otherwise
Perform step 210.
Specifically, when ray and each border have intersection point, it is necessary to judge whether each intersection point has the end of Arbitrary Boundaries
Point, if so, then needing to judge the position of two Borders and ray corresponding to the end points, so that it is determined that ray and each side
First quantity of boundary's intersection point is odd number or even number, if not provided, can with it needs to be determined that ray and each boundary intersection the
Two quantity.
For example, when ray g2 and border b1 have intersection point J, judge whether intersection point J is border b1, b2 and b3 respectively
End points；
When intersection point J is border b1 and border b2 end points, judge border b1 and border b2 whether in the same of ray g2
Side, if it is, the number of recording ray g2 and the intersection point on border is 0 or 2 any one even number, otherwise, recording ray g2
Any one odd number that number with the intersection point on border is 1 or 3.
When intersection point J is not the end points in border b1, border b2 and border b3, record intersection point J the first quantity.
Step 208：For each end points, whether two Borders are judged corresponding to current endpoint in the both sides of ray,
If performing step 209, step 210 is otherwise performed.
Specifically, when intersection point is the end points on some border, it is thus necessary to determine that two Borders are with penetrating corresponding to the end points
The position relationship of line, so that it is determined that the first quantity of ray and the intersection point on each border is odd number or even number.
Step 209：It is odd number to determine the first quantity, performs step 211.
Specifically, because the first quantity is default parameter, when two Borders of end points are in the both sides of ray, record
First quantity is odd number (such as 1 or 3).
Step 210：It is even number to determine the first quantity.
Specifically, when two Borders of end points are in the side of ray, the first quantity of record is even number (such as 2 or 0).
Step 211：Determine the second quantity of ray and the intersection point on the border beyond Border.
Specifically, because the second quantity is similarly default parameter, so appointing when ray and the intersection point on each border are present
Anticipate after the end points on border, continue to judge the of the border in addition to two articles of Borders corresponding to the end points and the intersection point of the ray
Two quantity.
For example, when intersection point J is border b1 and border b2 end points, determine whether ray g2 and border b3's has friendship
Point, if so, then the second quantity be 1, if without if the second quantity be 0.
Step 212：Judge whether the first quantity and the second quantity sum are odd number, if it is, performing step 213, otherwise
Perform step 215.
Specifically, it is odd number or even number according to the first quantity and the second quantity sum, it may be determined that changing coordinates point is
It is no in region to be counted.
For example, if the first quantity is 1, the second quantity is 0, then is odd number for 1 after addition, then changing coordinates point exists
In region to be counted；
If the first quantity is 1, the second quantity is 1, then is odd number for 1 after addition, then changing coordinates point is in area to be counted
It is overseas.
Step 213：Determine changing coordinates point in region to be counted.
Specifically, on any one border of changing coordinates point in region to be counted and when the first quantity and the second quantity
When extremely and being odd number, it may be determined that the coordinate points are in region to be counted.
Step 214：According to the quantity of the type of the coordinates logo information carried on internal coordinate point in region to be counted, it is determined that
The quantity of area's device within the domain to be counted.
Specifically, it is determined that area's device within the domain to be counted quantity when, only need to determine the coordinate points in region to be counted
The quantity of the coordinates logo information category of upper carrying, you can the quantity of tube apparatus is determined, by the quantity of point device and tube apparatus
Quantity is added, you can draws the total quantity of all devices in region to be counted.
For example, there are coordinate points d, corresponding coordinates logo information dd and coordinate points g1, correspondingly in region Y to be counted
Coordinates logo information gg, it may be determined that the total quantity of the equipment in region Y to be counted be 2.
Step 215：Determine changing coordinates point outside region to be counted.
Specifically, in ray corresponding to changing coordinates point and each border without any intersection point and in the first quantity and the second number
When amount sum is even number, it may be determined that changing coordinates point is outside region to be counted.
