Specific embodiment
It is described in detail below in conjunction with accompanying drawing specific embodiment of this disclosure.It should be appreciated that this place is retouchedThe specific embodiment stated is merely to illustrate and explains the disclosure, is not limited to the disclosure.
Fig. 1 is a kind of flow chart of the localization method according to an exemplary embodiment, as shown in figure 1, this positioning sideMethod can apply to, in positioner, comprise the following steps.
Step S11：The wireless signal that Bluetooth beacon equipment on destination object for the scan setting sends.
Step S12：According to wireless signal, send ranging information to server, so that server carries out to destination object determiningPosition.
Destination object can be the arbitrary object needing and being tracked positioning, can be people can also be article.For example,Destination object can be child, old man, the historical relic in museum, the commodity in market, etc., the embodiment of the present disclosure is not made to thisLimit.
In the embodiment of the present disclosure, Bluetooth beacon equipment can be arbitrarily can to carry spy by BLE technology to transmission aroundDetermine the equipment of the radio broadcasting signal of ID.For example, it may be the EddyStone (Bluetooth beacon platform of increasing income) being issued based on GoogleBeacon (beacon) standard, incessantly at a certain time interval to the equipment around sending EddyStone packet, etc.Deng.
At present, typically by multiple Bluetooth beacon device distribution in fixing place, user can pass through electronic equipment ratioThe wireless signal sending as the Bluetooth beacon equipment that mobile phone scans stationary distribution, and then know itself current position.And this public affairsOpen in embodiment, Bluetooth beacon equipment is not stationary distribution, but Bluetooth beacon equipment is arranged on the target wanting tracing and positioningOn object, by positioner scanning signal, and then realize the destination object carrying Bluetooth beacon equipment is positioned.ThereforeBluetooth beacon device fabrication can be become less portable construction, for example, it is possible to Bluetooth beacon device fabrication is thickness 5 milliRice SMD, be equipped with the equipment of small-sized button cell, etc., the construction of the embodiment of the present disclosure pair and Bluetooth beacon equipment is notIt is construed as limiting, as long as can be carried by target device to be positioned.
Positioner can be stationary distribution indoors or outdoor device, can be according to the actual scanning of positionerScope meets distribution determining positioner.For example, apply in the indoor destination object of positioning, the historical relic in such as museumWhen, Bluetooth beacon equipment is arranged on historical relic, multiple positioners are distributed in museum, such as each room setting oneIndividual positioner, etc..Or for example, apply in the outdoor destination object of positioning, such as multiple positioners can be dividedOn the street lamp that cloth is disposed in the outdoor, etc..Certainly, either indoor positioning or outdoor positioning, the positioner quantity of settingMore, positioning is more accurate.
Ranging information can serve to indicate that the distance between positioner and destination object, and positioner is scanning indigo plantDuring the wireless signal that tooth beacon equipment sends, ranging information can be sent to server according to the wireless signal scanning, and thenServer is positioned to destination object according to ranging information.How by ranging information, service be sent to for positionerDevice, the embodiment of the present disclosure is not construed as limiting, for example can be by WiFi (WIreless-Fidelity, WLAN) to serviceDevice sends ranging information, or can also send in other way.
For ranging information specifically which kind of information, and how positioner determines ranging information, the embodiment of the present disclosureIt is not construed as limiting, below possible mode is illustrated.
Optionally, according to wireless signal, to server send ranging information, can according to the signal strength signal intensity of wireless signal,Determine RSSI (Received Signal Strength Indication, the received signal strength indicator) value of wireless signal, soSend RSSI value to server afterwards.
Generally, Bluetooth beacon equipment and positioner from must more close to, signal is stronger, more far away, and signal is weaker.So logicalCross the power of the signal that RSSI value can reflect that location equipment receives, positioner after RSSI value is sent to server,Server can calculate the distance between destination object and this positioner according to RSSI value, and then realizes to destination objectPositioning.By such mode, using BLE technology, can preferably realize indoor and outdoor while reducing the power consumption of equipmentPositioning to destination object.
Optionally, send RSSI value to server, can first determine the mean value of N number of RSSI value of acquisition, then to clothesThe mean value that business device transmission calculates.Wherein, N is the positive integer more than or equal to 2；
Due in actual applications, RSSI value there may be unstable, therefore the multiple RSSI value determining can be made evenAll, then send mean value to server.Value for N is how many, and the embodiment of the present disclosure is not construed as limiting, and for example, N can be 5,So namely mean value computing is carried out to the RSSI value of 5 determinations.Because the time interval of actual acquisition signal is very short, such as300ms about, therefore, retransmit after the mean value taking n times RSSI value, dynamic location efficiency can't be affected.By soMode, can more precisely destination object be positioned, lifting positioning reliability.
Fig. 2 is a kind of flow chart of the localization method according to an exemplary embodiment, as shown in Fig. 2 this positioning sideMethod can apply to, in server, comprise the following steps.
Step S21：Receive the ranging information of at least one positioner transmission.
Step S22：The ranging information being sent according at least one positioner, positions to destination object.
That is, server is previously stored with the position of each positioner, device is receiving one or morePositioner send the ranging information for same destination object after, can according to the whole ranging information receiving, andThe position that fixing device is located, positions to destination object.The mode positioning will be illustrated below.
When the ranging information for destination object that server receives only that positioner sends, for example, receiveTo positioner 1 send the RSSI value for indicating distance, server pass through RSSI value can be calculated destination object andThe distance of positioner 1 is 10 meters, then it is considered that destination object is located at centered on positioner 1, radius is 10 metersOn circular scope border.
When the ranging information for same destination object that server receives that multiple positioners send, for example, pleaseReferring to Fig. 3, the RSSI value for indicating distance that server receives positioner 1 transmission shows positioner 1 distance objectiveObject has 10m, and the RSSI value receiving positioner 2 transmission shows that positioner 2 distance objective object has 15m, then such as Fig. 3Shown it may be determined that destination object be located in figure point A be located position.
Certainly, positional information, after the positional information obtaining destination object, such as can be sent to user by serverMobile phone, to inform the position of ownership goal object.
By way of above, server can position to destination object more conveniently.
Optionally, at least one positioner at least includes the first positioner, receives at least one positioner and sendsRanging information, the first ranging information that the first positioner sends can be received, the first ranging information can serve to indicate that theThe distance between one positioner and destination object, in preset duration, detect whether to receive its in addition to the first positionerThe ranging information corresponding to destination object that his positioner sends.The ranging information being sent according at least one positioner,Destination object is positioned, Ke Yishi, if receive in preset duration other positioners transmission corresponding to target pairThe ranging information of elephant, then according to the ranging information all corresponding to destination object receiving, position to destination object；OrPerson, if be not received by the ranging information corresponding to destination object of other positioners transmission, basis in preset durationFirst ranging information, positions to destination object.
Preset duration can be duration set in advance, such as, can set preset duration as 0.5s, 0.1s, etc., thisOpen embodiment is not construed as limiting to this.
That is, server can receive the first range finding letter for destination object that the first positioner sendsAfter breath, can detect whether in preset duration that also other positioner has also scanned the Bluetooth beacon that destination object carriesThe signal that equipment sends, if any, the survey that whole positioners scanning destination object send can have receivedCalculate the position of destination object again after information, without if, the first survey of just only being sent according to the first positionerPosition away from the rough calculating destination object of information.So, server can more preferably, quickly be realized destination object is determinedPosition.
