The purpose of the embodiment of body, it is not intended that in the limitation present invention.Each technical characteristic of above example can carry out arbitrary group
Close, to make description succinct, combination not all possible to each technical characteristic in above-described embodiment is all described, however,
As long as contradiction is not present in the combination of these technical characteristics, the scope of this specification record is all considered to be..
Referring to Fig. 1, one embodiment of the bluetooth indoor orientation method in the embodiment of the present invention includes：
101st, multiple Beacon base stations of mobile terminal and the interior arrangement of scene carry out Bluetooth communication, measure the mobile terminal
Receive the signal reception power for the Bluetooth signal that the multiple Beacon base stations are sent.
In the present embodiment, multiple Beacon base stations are first arranged in scene.It can be interior on the scene, for example open up
The indoor application environment such as shop, museum, conference and exhibition center, also it can apply the present invention to outdoor according to actual conditions certainly.
Beacon (Chinese " beacon ", " beacon ") is a kind of " neighbor systems (Proximity System) ".Within the system, operate in
The signal that smart mobile phone, tablet personal computer, the application on wearable or other computing devices can be sent to " Beacon equipment " enters
Row response.Beacon is exactly that one kind realizes pinpoint set by low-power Bluetooth technology (Bluetooth Low Energy)
Standby, indoor one Beacon signal transmitting base station of placement, this base station can create a signal area, actively be carried out without user
Information search, corresponding program will be carried actively when user carries mobile device (for example mobile phone) entering signal region
Show whether user needs to access this signal network, the application program in mobile phone launches base according to the Beacon signals of reception afterwards
The signal reception power of the Bluetooth signal sent of standing calculates the distances of mobile phone distance Beacon signal transmitting base stations, so as to accurate
User is positioned.It is prior art on Beacon base stations, beacon base stations constantly send beacon broadcasting packets, should
Message includes transmission power, i.e. signal intensity.The mobile terminal can be the mobile terminals such as mobile phone, tablet personal computer.The movement

The positional information of Beacon base stations, the current location information of mobile terminal can be drawn by multipoint positioning algorithm.The position
Information can be two-dimensional coordinate or three-dimensional coordinate or latitude and longitude information etc..The present embodiment utilizes each beacon of distance of mobile terminal
The distance of base station and the position of each Beacon base stations, you can the function of multipoint positioning is realized, by multipoint positioning algorithm, from
And calculate the current location of mobile terminal.Have a variety of implementations on specific location algorithm, in Beacon technologies and
Have in iBeacon technologies, be no longer described in detail herein.Calculating is placed on server end by the present embodiment, so as to greatly reduce movement
The resource utilization of terminal so that faster, positioning is more accurate for locating speed.
103rd, the mobile terminal receives positional information and cartographic information and the corresponding display that the server is sent.
In the present embodiment, cartographic information and the positional information being calculated are handed down to mobile terminal by server in the lump, so
Mobile terminal can correspond to the positional information that reality is current in cartographic information afterwards, show user to watch, so as to realize bluetooth
Indoor positioning.
It is preferably, described to obtain the positional information of the mobile terminal according to the ranging parameters and signal reception power,

It is worth operation function.
In practical application, easier in order to calculate, A is that the bluetooth module distance of Beacon base stations and mobile terminal is
The power received at 1 meter, in general, A is general constant, that is, ranging parameters.Namely, it is preferable that described pre-
Set a distance is 1 meter.Further, when the preset distance is 1 meter, the value of the ranging parameters and the value of signal reception power
It is identical.
Then, the model of the ranging parameters measured and corresponding mobile terminal is sent to server associated storage.Clothes
Ranging parameters corresponding to multiple models, and the ranging parameters more than one of each model are stored with business device.As long as in step 201
The mobile terminal skip of measurement is more, then the data that server obtains in step 202 are with regard to more.Then, server is to these data
Handled, according to corresponding to the model of the multiple mobile terminal and corresponding ranging parameters obtain each model mobile terminal
Ranging parameters.
Preferably, the model and corresponding ranging parameters according to the multiple mobile terminal obtains each model movement
Ranging parameters corresponding to terminal, including：
The ranging parameters of the multiple mobile terminal are classified according to model；
To being filtered processing with multiple ranging parameters of a model, then it is averaging to obtain ranging corresponding to the model and joins
Number.
In the present embodiment, if being stored with server with a multiple measurement A Value Data for model mobile terminal, server pair
A values can first carry out filtering process, filter out the too big irrational numerical value of error, then the A values to belonging in reasonable orientation take
Average value processing, the mobile terminal skip so measured is more, and obtained ranging parameters are more accurate.
