Embodiment
With reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention is wherein described.
Fig. 1 is the schematic diagram of an embodiment of Site Survey method of the present invention.As shown in Figure 1, the method step of the present embodiment is as follows:
The Site Survey method providing based on the above embodiment of the present invention, by locating information is carried out to data mining, extract the useful information in user positioning request, thereby obtain the wherein position of unknown access point, thereby can reduce location cost, keep the higher real-time of data.
Because the UAP positional information precision obtaining is in this way lower, for fear of other localization process is impacted, can the priority level of this UAP be made as low.
Fig. 2 is the schematic diagram of another embodiment of Site Survey method of the present invention.Wherein, in the embodiment shown in fig. 1, step 106 and 107 can be specially:
Be specifically described below by an example.
If find, UAP1 does not exist in existing AP database, therefore in UAP data acquisition system, sets up UAP1 group, comprises 12 locating information in this group, and particular content is as follows:
1、AP1RSSI1；AP2RSSI2；AP3RSSI3；UAP1RSSIa；2012-04-1010:09:43；116.3613472220，39.9388055550，30
2、AP4RSSI4；AP5RSSI5；AP6RSSI6；UAP1RSSIb；2012-04-1010:20:41；116.3613405430，39.9388155330，25
……
12、APx?RSSIx；APy?RSSIy；APz?RSSIz；UAP1RSSIn；2012-04-1412:20:41；116.3613405430，39.9388155330，60
Wherein comprise 3 partial contents every locating information.Part I is mark and the signal strength signal intensity of AP, and Part II is the time that Location Request is initiated, and Part III is positioning result.
For example, in the 1st article of locating information, AP1RSSI1 is mark and the signal strength information of known AP1, UAP1RSSIa is mark and the signal strength information of UAP, and 2012-04-1010:09:43 is the time that Location Request is initiated, 116.3613472220,39.9388055550, the 30th, positioning result.Given here is three-dimensional result, and positioning result can be also the 2-D data in plane certainly.
For the locating information in UAP1 group, first sort.Signal strength signal intensity absolute value and position error absolute value by UAP1 in each locating information are added.Then according to result order from small to large, locating information is arranged.Wherein position error is to obtain in advance according to the deviation between positioning result and physical location.
Utilize the signal attenuation formula of free space to calculate the position that UAP1 is possible.Formula is as follows:
Pr=Pt-PL(d)=Pt-PL(d
0)-10nlog(d/d
0)-FAF
Wherein Pr is the signal strength signal intensity receiving, and Pt is UAP transmitted power, and PL (d) is path attenuation, PL (d
0) for distance A P be d
0the path attenuation at place, n is path loss coefficient, FAF is shadowing factor.By above-mentioned formula, can estimate the possible position of UAP1.
Can be by above-mentioned fortran:
Wherein, n
afor path loss coefficient, different Experimental Areas is adopted to different values according to actual measured results, WAF is the wall decay factor that need to measure by experiment, d
ffor being equivalent to the scope of free space around transmitting antenna, conventionally establish d
fbe 3 meters, conventionally establish d
0be 1 meter, now PL (d
0) be 40dB.
Utilize above-mentioned formula, can utilize each locating information to obtain the distance d of UAP1 at a distance of positioning result, can obtain thus the UAP1 position range possible with respect to positioning result.If positioning result is three-dimensional data, the position range obtaining is that Radius is the spherical of d.Consider that obtained elevation information confidence level is not high, be unfavorable for obtaining positioning result, therefore can utilize the projection of the position range obtaining on horizontal plane to judge.In this case, the UAP1 position range possible with respect to positioning result is that radius is the circle of d.
According to putting in order, first utilize front 3 locating information, calculate respectively 3 possible position ranges of UAP1, if these 3 circles exist common common factor, using the position of corresponding position as UAP1 of occuring simultaneously.If there is not common common factor in these 3 circles, select successively next locating information to process, the like, until obtain 3 common factors that circle is common.

Fig. 4 is the schematic diagram of unknown another embodiment of Site Survey of the present invention.Preferably, in order to improve the robustness of system, can be before processing, by the signal strength signal intensity of UAP in each locating information certain scope that fluctuates, for example fluctuate 5%, obtain signal strength signal intensity a and b, utilize respectively a and b to calculate, thereby can obtain an annulus, can be conducive to like this location of UAP.
Preferably, in each group, locating information being sorted before processing, first locating information is carried out to Screening Treatment.
Fig. 5 is the schematic diagram that the present invention screens an embodiment of unknown access point.As shown in Figure 5, in the step 105 shown in Fig. 1, can comprise:
The sign of AP is mainly made up of the information such as MAC Address, SSID at present, and part AP producer may adopt and repeat MAC Address for AP, thereby same MAC may appear at multiple geographical position.Due to data screened deletion of meeting in location database of this part AP, so this part locating information need to be rejected.That is, deletion contains same UAP and positioning result differs locating information more than A rice, and A generally gets 2km at present.
Fig. 6 is the schematic diagram that the present invention screens unknown another embodiment of access point.Because AP data exist not stationarity, for example mobile phone moves the AP data of AP, data card AP or short time unlatching, and therefore the position of this part AP is not long-term fixing, may exert an influence to positioning result if introduce the AP of this part.Therefore need such locating information to delete.Conventionally UAP for the first time the distance between time of occurrence and last time of occurrence be greater than 72 hours.
