Number strongest several AP of intensity can be generally thought in same plane region (namely same floor), and therefore, the present embodiment is preferred
Using specific location of the three-point fix technological orientation current mobile terminal in floor, the particular content of three-point fix algorithm is such as
Under:
Known 3 position coordinates (x1, y1), (x2, y2), (x3, y3) and known unknown point coordinate (x0, y0) are to three
Distance d1, d2, d3 of point, ask unknown point coordinate (x0, y0).
Make three circles by radius of d1, d2, d3, according to Pythagorean theorem, obtains the position meter of the i.e. unknown point of intersection point
Calculate formula:
(x1-x0)2+(y1-y0)2=d12;
(x2-x0)2+(y2-y0)2=d22;
(x3-x0)2+(y3-y0)2=d32;
Wherein, distance d1, d2, d3 is calculated by following range formula:
D=10^ [(abs (db)-A)/(10*n)];
Wherein, d indicates the distance between signal transmitting terminal and receiving end;Db indicates transmitting terminal received by receiving end

Signal strength, be constant;N indicates the environmental attenuation factor, is constant.Wherein, n can be adjusted according to the difference of environment,
Namely environment is different, n value is not also identical.
In the present embodiment, A and n are empirical value, the environment of specific value and the hardware node and radio signal propagation that use
It is closely related, so two empirical values must be demarcated in advance in application environment before ranging.By above-mentioned range formula it is found that
Under the premise of A and n is determined, due to the signal strength for each wireless aps that known mobile terminal receives, above-mentioned distance is public
It is linear equation with one unknown about distance d that formula is practical, and the signal strength for each wireless aps that mobile terminal is received substitutes into above-mentioned
Range formula can calculate the distance between mobile terminal and each wireless aps d1, d2, d3.
In the present embodiment, after floor locating for current mobile terminal has been determined, by above-mentioned three-point fix algorithm, based on each
The distance between the position of wireless aps and each wireless aps, can be calculated current mobile terminal in the specific position of current floor
It sets.It should be noted that the selected wireless aps quantity of this phase orientation is preferably greater than three, the AP quantity for calculating is got over
It is more, it is concluded that mobile terminal candidate coordinate it is also more, and then the accuracy of calculating can be promoted.

Step D: repeating step A to step C, until there is no the wireless aps for having neither part nor lot in region division, wherein same
A sample wireless aps are only involved in a region division.
In the present embodiment, indoor positioning device first carries out region division to each floor respectively, and a region can be regarded as
Same floor is also divided into multiple and different environmental areas by one environment, and varying environment region corresponds to different environmental attenuations
Factor of n and unit signal intensity A.
The difference of positional distance is specifically based in the present embodiment to discern whether in the same environmental area, for example, certain
One AP detection is to there are 5 other AP around it, then the adjacent AP for selecting 3 distances nearest from the adjacent AP of the AP, with
A quadrangle (position coordinates that the vertex of quadrangle is four AP) are constructed, the surrounded region of the quadrangle constitutes a ring
Border region.When dividing next environmental area, the wireless aps for also having neither part nor lot in region division are selected, then according to above-mentioned side
Formula constructs another quadrangle, to obtain next environmental area.It should be noted that the division of environmental area can be by
Tessellation is also possible to divide by quadrangle or pentagon, and each region that divides can be the AP of corresponding identical quantity,
It is also possible to the AP of corresponding different number, is configured with specific reference to actual needs.
In the present embodiment, after completing the band of position and dividing, it is based on range formula, it is corresponding that the environmental area can be found out
Environmental attenuation factor of n and unit signal intensity A, specific calculation are as follows:
According to formula d=10^ ((abs (db)-A)/(10*n)), the linear equation in two unknowns about d (A, n) is solved, wherein
D is the distance between difference AP coordinate in same environmental area, is known;Db is that difference AP is mutually detected in same environmental area
