Description
Technical field
The present invention relates to electronic information field, particularly relate to the indoor and outdoor localization method of a kind of low-power consumption.
Background technology
Along with the development of technology of Internet of things, the demand of all things on earth interconnection is persistently risen with expectation, particularly exists by society
Indoor positioning field, the demand of location scene gets more and more, and this also promotes the development in localization method field, and people are at present
Application demand propose many and obtain the scheme of location information, as GNSS, WiFi localization method, bluetooth localization method, RFID,
The technology such as UWB.
Indoor positioning market prospect is extensive at present, and iBeacon is the technical scheme that Apple releases, and opens indoor positioning
The new entrance of application, numerous indoor positioning schemes based on this technology are arisen at the historic moment.
Scheme one:
At indoor deployment iBeacon localizer beacon, beacon sends framing signal, owing to sending framing signal in each second
Time is only several milliseconds, and therefore localizer beacon power consumption is extremely low, can be reached more than 5 years by battery use of powering, and localizer beacon is installed
Convenient, implementation cost is low.
Receive terminal and continue the framing signal of detection and location beacon transmission and by communication technologys such as Wi-Fi, 2G, 3G, 4G
Transfer data to background system, backstage alignment system carry out position calculation.Receive terminal and persistently carry out framing signal scanning
And communication work, power consumption of terminal and cost are the highest, significantly limit its application.
Scheme two:
At indoor deployment bluetooth detector, people or article wear or disposes Bluetooth label, label sending bluetooth
Signal, bluetooth detector receives this signal and passes through network by signal return to background system, background system calculating location knot
Really.
This kind of mode Bluetooth label has only to the framing signal several milliseconds of middle transmission per second, and tag power consumption is low, during use
Between long, low cost.But bluetooth detector continues the location information of detecting bluetooth label transmission and by WiFi, 3G, 4G or netting twine
Transferring data to background system etc. communication technology, therefore bluetooth detector needs external power supply or POE netting twine, and bluetooth detector becomes
This height, disposes and implements cost greatly, significantly limit the application of this kind of mode.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the indoor and outdoor localization method of a kind of low-power consumption, combines
The advantage stating scheme one, two, uses LPWAN (Low-Power Wide Area Network, low-power consumption Wide Area Network) technology,
In the case of network design cost is suitable with existing scheme one, location terminal or the continuation of the journey of label and stand-by time reach scheme
The level of two, greatly improves actual promotional value.
To this end, the present invention provides the indoor and outdoor localization method of a kind of low-power consumption, comprise the steps:
S1, disposing low-power consumption location node in required indoor environment, described low-power consumption location node includes that bluetooth positions
Beacon；
S2, after receiving terminal receives location information, use LPWAN technology realize low power consumption transmission location information to backstage
Monitoring system, is completed indoor positioning by backstage.
Further, step S3 is also included: employing satellite navigation system positions in outdoor, and satellite navigation system is defeated
The longitude and latitude result gone out is back to backstage by LPWAN, it is achieved the comprehensive location of indoor and outdoor.
Further, described LPWAN technology is ultra long haul low power consumption data transmission technology LoRa, protenchyma based on honeycomb
One in networking technology NB-IoT.
Further, the one during described receiving terminal is location label, bracelet, chest card.
Further, receiving terminal receive and detected by receiving terminal by the location information of LPWAN technical transmission
No. ID arrived and signal intensity.
In step S2, carry out one-time positioning signal detection and transmission at set intervals；When sensor sensing to personnel or
Article do not move then automatically into resting state, when sensing that personnel or item motion then automatically waken up, enter duty.
3-axis acceleration value in sensor sample a period of time, and three axles every time sampled in calculating this time period are total
AccelerationWhen the variance of three axle total acceleration values is more than gate value, then it represents that personnel or article are transported
Dynamic, on the contrary represent static.
Preferably, when the numbering that receiving terminal detects the iBeacon localizer beacon that signal is the strongest does not change, then
Do not carry out location information data on respond with reduce receiving terminal power consumption；Otherwise, when the strongest iBeacon localizer beacon of signal
Numbering changes, then upload location information is to background system, carries out the renewal of positional information.
Preferably, when receiving terminal receives the signal of indoor low-power consumption location node, satellite navigation module does not works；When
Receiving terminal can not receive the signal of indoor low-power consumption location node, then satellite navigation module is started working, it is achieved location mould
The conversion of formula.
Further, LPWAN embedded in base station satellite navigation module the textual information of real-time reception satellite navigation system, when
When receiving terminal startup satellite navigation locating module positions, the textual information of known satellite navigation is passed through by LPWAN base station
LPWAN technology is quickly sent to receiving terminal, and receiving terminal utilizes the auxiliary of this information to realize satellite fix rapidly.
Compared with prior art, the present invention uses and disposes the low-power consumption location nodes such as bluetooth localizer beacon in indoor environment,
Use LPWAN technology realize low power consumption transmission location information to background monitoring system, backstage complete indoor positioning, meanwhile,
Outdoor employing satellite navigation system positions, after the longitude and latitude result that satellite navigation system exports being back to by LPWAN
Platform, it is achieved the comprehensive location of indoor and outdoor, had both overcome the problem that in prior art, cost is high and power consumption is high, and when sensor sense
Personnel should be arrived or article do not move then automatically into resting state, be effectively increased continuation of the journey and stand-by time, greatly improve reality
Border promotional value.
Accompanying drawing explanation
Fig. 1 is the method flow diagram of the present invention.
Detailed description of the invention
Below embodiments of the invention are described in detail.
Referring to Fig. 1, the present invention provides the indoor and outdoor localization method of a kind of low-power consumption, comprises the steps:
S1, disposing low-power consumption location node in required indoor environment, described low-power consumption location node includes that bluetooth positions
Beacon；
S2, after receiving terminal receives location information, use LPWAN technology realize low power consumption transmission location information to backstage
Monitoring system, is completed indoor positioning by backstage；
