Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description:
Fig. 1 is the structural framing figure of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings:
A kind of LPWAN high-precision locating method, it is characterised in that including some Beacon equipment, positioning terminal, LPWAN nets Network, location-server, user APP;
The Beacon equipment is installed on localization region, and the Beacon equipment launches broadcast message to positioning terminal;It is described fixed The broadcast message that position terminal sends several Beacon equipment received is packed, and by LPWAN networks, is sent to positioning service Device;Location-server provides positioning result by location algorithm, and positioning result is pushed into user APP;User APP receives fixed The positioning result of position server.
Foregoing a kind of LPWAN high-precision locating method, it is characterised in that user APP can actively receive positioning service The positioning result of device, it can passively receive the positioning result of location-server.
Foregoing a kind of LPWAN high-precision locating method, it is characterised in that the Beacon equipment is to be based on LPWAN The signal broadcasting equipment of the communication technology, each Beacon equipment have a unique ID.
Foregoing a kind of LPWAN high-precision locating method, it is characterised in that the Beacon equipment is supplied using battery Electricity, removable, convenient deployment can be fixed.
Foregoing a kind of LPWAN high-precision locating method, it is characterised in that positioning terminal is the terminal based on LPWAN.
Foregoing a kind of LPWAN high-precision locating method, it is characterised in that Beacon equipment and positioning terminal can be selected Dormancy is selected, separated in time is waken up once, and Beacon equipment does time synchronized with positioning terminal.
A kind of foregoing LPWAN high-precision locating method, it is characterised in that location-server:If according to what is received ID, signal intensity, signal to noise ratio corresponding to dry beacon, provide positioning result, location algorithm can be by location algorithm Fingerprint algorithm or multilateration.
The each equipment of Beacon equipment has a unique ID, the ID of Beacon device broadcasts oneself and related letter Breath.In order to save power consumption, Beacon equipment can send out broadcast message with relatively low transmission power.In order to save electricity, Beacon is set Standby and positioning terminal can select dormancy, and separated in time is waken up once, when this needs the Beacon equipment to be done with positioning terminal Between it is synchronous.LPWAN networks can send time synchronized message to Beacon equipment and positioning terminal, Beacon equipment and positioning terminal When receiving synchronization message, the time of oneself can be corrected.It so may insure that positioning terminal can receive the broadcast frame of Beacon equipment.
Mobile Beacon equipment, then when sending broadcast frame, device identification, the positional information of itself of oneself can be taken (Such as GPS longitudes and latitudes)If fixed Beacon equipment then need to only broadcast the device identification of oneself.Positioning terminal intercepts week The Beacon equipment on side, when receiving-Beacon device broadcasts signals, analytic signal intensity and signal to noise ratio, receive a number of After Beacon equipment, all Beacon device identifications received and corresponding signal intensity and signal to noise ratio are assembled in one Rise, location-server is sent to by LPWAN networks.
ID of the location-server according to corresponding to several Beacon equipment received, signal intensity, signal to noise ratio, position Information, positioning result is provided by location algorithm, location algorithm can be fingerprint algorithm or multilateration.Fingerprint algorithm needs The finger print data for gathering abundance is trained, and can be trained with machine learning, deep learning scheduling algorithm.Multilateration needs Want the attenuation model of evaluating wireless signal
For 500m*400m outdoor, the positioning precision for only needing 10 Beacon equipment to meet 10 ~ 30 meters, 10 The cost of Beacon equipment only needs thousands of members.
LPWAN Beacon coverage distance, penetrability are also considerably beyond bluetooth, WIFI, and cost and bluetooth, WIFI mono- Cause, therefore can be used for indoor positioning, and only need a small amount of Beacon equipment, and Beacon equipment can directly pass through LPWAN reports the equipment state of itself, and such as electricity, position, maintenance cost are lower.For example, for 5 layers of mall, every layer 100m*100m, because beacon penetrability, each layer can receive the beacon broadcast frames of other layers, then every layer only needs 10 Beacon, 50 beacon are only needed altogether, you can meet 3 ~ 5 meters of positioning precision, 50 beacon costs altogether Only ten thousand yuan or so.And bluetooth positions, each layer is required for hundreds of Bluetooth beacons, needs 2000 Bluetooth beacons altogether, And Bluetooth beacon does not support data back in itself, it is also necessary to increases data back equipment, construction cost, maintenance cost are all too It is high.
Illustrated below with the LoRa technologies in LPWAN technologies, the reality based on the LPWAN technologies such as NB-IOT, SigFox, RPMA Existing process is similar.
Beacon equipment based on LoRa, broadcast beacon frames are supported, time synchronized is done by LoRa networks, passes through LoRa Network reports electricity, positional information, support dormancy and the wake-up of itself.Broadcast beacon frame Portable device ID, mobile beacon Also need to support GPS(Or the Big Dipper), positional information can be carried in broadcast message.Transmission power as little as 0dbm, transmitting one in every 10 seconds Secondary broadcast frame, 3500mAh batteries can continue a journey at least 5 years.
Positioning terminal based on LoRa, time synchronized is done by LoRa networks, can dormancy and wake-up, to guarantee to receive Beacon broadcast frame.After wake-up, beacon broadcast frames are intercepted, after certain amount beacon broadcast frame is received, will be received All beacon ID and corresponding signal intensity and signal to noise ratio fit together, positioning clothes are sent to by LoRa networks Business device.In addition, positioning terminal can report the information about power of itself by LoRa networks.Wake-up in every 5 minutes once positions, 3500mAh batteries can continue a journey at least 5 years.
LoRa networks are, it is necessary to support to issue time synchronized message to Beacon and positioning terminal.
Location-server, ID, signal intensity, signal to noise ratio according to corresponding to several beacon received, by fixed Position algorithm provides positioning result, and location algorithm herein is fingerprint algorithm, gathers the finger print data of abundance, is calculated with deep learning Positioning result is trained and provided to method.
The beneficial effects of the invention are as follows:Beacon and positioning terminal are all based on LPWAN technologies, in terms of positioning, power consumption It is far superior to 2G/3G/4G the and LPWAN base stations of public network with cost, and with battery powered, can meets the continuation of the journey of several years, Therefore can be in outdoor and indoor Scaledeployment, beacon is more, and positioning precision is higher.
Described above is only the preferred embodiment of the present invention, it should be pointed out that:For the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
