Raws li peb paub, hauv cov ntsiab lus ntawm Is Taws Nem ntawm Yam, qhov tau txais thiab siv cov ntaub ntawv qhov chaw tau dhau los ua qhov tseem ceeb. Piv nrog rau qhov chaw sab nraum zoov, qhov chaw ua haujlwm ntawm qhov chaw sab hauv tsev yog qhov nyuaj thiab muag heev, thiab nws cov cuab yeej siv tau ntau yam. Piv txwv li, cov neeg ua haujlwm ntse ntawm lub Hoobkas thiab kev tswj xyuas cov khoom thauj thiab kev teem sijhawm, kev tswj xyuas kev nyab xeeb, kev tshawb nrhiav tsheb hauv av hauv av, cov neeg ua haujlwm ntse hauv tsev / tus qhua qhov chaw tswj xyuas, kev nthuav qhia qhov chaw navigation, thiab lwm yam.
Feem ntau, peb tuaj yeem faib cov cuab yeej hauv tsev tso rau hauv Wi-Fi positioning, ZigBee positioning, Bluetooth positioning, UWB positioning, RFID positioning, satellite positioning, low-frequency trigger positioning, base station positioning, acoustic positioning, optical positioning, geomagnetic positioning, etc. thiab Bluetooth.
Wi-nkaus module
Qhov chaw Wi-Fi tau pib siv rau hauv thaj chaw ntawm kev saib xyuas cov neeg ua haujlwm raws li qhov chaw cim npe nyob ib puag ncig xyoo 2010. Xyoo 2013, cov ntawv thov xws li Wi-Fi nrhiav pom raws li cov xov tooj ntawm tes kuj tau tshwm sim.
Tam sim no, Wi-Fi positioning yog ib qho nrov sab hauv tsev siv tshuab, thiab nws txoj kev muab tso rau raws li lub teeb liab lub zog propagation qauv qauv thiab txoj kev paub tus ntiv tes.
Lub teeb liab lub zog propagation qauv txoj kev hais txog kev siv ib qho channel fading qauv xav nyob rau hauv ib puag ncig tam sim no los kwv yees qhov deb ntawm lub davhlau ya nyob twg thiab qhov chaw paub AP raws li nws txoj kev sib raug zoo lej. Yog tias tus neeg siv hnov ntau lub cim AP, nws tuaj yeem dhau los ntawm peb sab Kev Tso Cai algorithm kom tau txais cov neeg siv cov ntaub ntawv qhov chaw; Txoj kev txheeb xyuas tus ntiv tes yog raws li cov yam ntxwv nthuav tawm ntawm Wi-Fi teeb liab, cov ntaub ntawv tshawb pom ntawm ntau APs tau muab tso rau hauv cov ntaub ntawv ntiv tes, thiab qhov ua tau ntawm qhov khoom txav mus los yog kwv yees los ntawm kev sib piv nrog cov ntaub ntawv siv.
Hauv qee qhov xwm txheej uas qhov chaw qhov tseeb yog qib ntsuas, Wi-nkaus tuaj yeem siv rau kev pab them nqi. Cov tshuab no yog tsim rau kev tso chaw thiab kev taw qhia ntawm tib neeg / tsheb, tsev kho mob, khw khw, chaw ua si, thiab lwm yam xwm txheej.
Bluetooth module
Nyob ib ncig ntawm 2014, Bluetooth-based positioning thev naus laus zis tau pib siv rau hauv kev saib xyuas thiab tso chaw.
Thaum Lub Xya Hli 2017, Bluetooth mesh tau tshaj tawm. Hauv ib xyoos thiab ib nrab, ntau tshaj 105 cov khoom lag luam nrog Bluetooth mesh network ua haujlwm tau lees paub, suav nrog cov chips, cov txheej txheem pawg, cov khoom siv, thiab cov khoom lag luam davhlau ya nyob twg.
Txhawm rau kom ua tau raws li qhov xav tau ntawm kev lag luam qhov chaw pabcuam, tus qauv tshiab Bluetooth 5.1 tau ntxiv cov kev taw qhia ua haujlwm, uas tuaj yeem pab lub cuab yeej kom paub meej cov kev taw qhia ntawm lub teeb liab Bluetooth, thiab tom qab ntawd pab tus tsim tawm los txhais cov kev daws teeb meem ntawm Bluetooth. cov cuab yeej kev taw qhia kom ua tiav qhov chaw centimeter-theem Precision Bluetooth positioning system.
Qhov chaw-raws li Bluetooth kev pabcuam daws teeb meem feem ntau muab faib ua ob pawg: cov kev daws teeb meem sib thooj thiab qhov chaw ua haujlwm. Txawm hais tias nws yog qhov chaw nyob hauv lub sijhawm lossis qhov chaw nyob sab hauv tsev, lub hauv paus ntsiab lus zoo ib yam. Ntawd yog, RSSI (tau txais lub teeb liab lub zog) mechanism yog ntxiv rau cov ntaub ntawv xa mus, thiab qhov kwv yees ntau ntawm cov khoom yog virtualized los ntawm RSSI. Kev ntsuas algorithm, thiab thaum kawg ua tiav qhov chaw sab hauv tsev.
Bluetooth tso chaw, tsuav yog lub cuab yeej Bluetooth ua haujlwm tau qhib, koj tuaj yeem nrhiav nws. Nrog kev tso tawm ntawm Bluetooth 5.x thiab ntau ntau lub xov tooj smartphones / ncoo / laptops kev koom ua ke nrog Bluetooth, Bluetooth xav tias yuav coj ntau qhov sib koom los ntawm qhov chaw ua lag luam. Raws li "2019 Bluetooth Market Update", qhov chaw pabcuam tau dhau los ua qhov kev daws teeb meem loj tshaj plaws ntawm Bluetooth, thiab nws qhov kev loj hlob txhua xyoo yuav tsum ncav cuag 43% hauv tsib xyoos tom ntej.
Bluetooth positioning yog siv rau ob qho tib si me me thiab loj qhov chaw ntawm tib neeg / khoom vaj khoom tsev, xws li ib-storey tsev los yog khw, exhibition halls, stadiums, warehouses, factories.

Nyob rau hauv xyoo tas los no, raws li UWB nti cov kev daws teeb meem tau loj hlob thiab cov nqi tau poob, cov tuam txhab lag luam hauv tsev kawm UWB txoj hauj lwm thev naus laus zis tau tshwm sim. UWB yog lub wireless positioning thev naus laus zis nrog kev sib kis tau zoo (txog 1000Mbps lossis ntau dua), tsis muaj zog xa tawm thiab muaj peev xwm nkag mus tau zoo.
UWB qhov chaw yog ntau lub sensor siv TDOA (Lub Sijhawm Sib Txawv ntawm Kev Tuaj Txog, lub sijhawm tuaj txog qhov sib txawv) thiab AOA qhov chaw ua haujlwm algorithm los tshuaj xyuas cov ntawv sau npe, nrog rau ntau txoj kev daws teeb meem, qhov tseeb siab, qhov tseeb qhov chaw tuaj yeem ncav cuag centimeter-theem thiab lwm yam ntxwv.
TDOA yog ib txoj hauv kev uas siv lub sijhawm sib txawv ntawm qhov tuaj txog, tseem hu ua hyperbolic positioning. Daim npav tag xa UWB teeb liab sab nraud, thiab txhua qhov chaw nres tsheb hauv lub wireless them ntawm tag yuav tau txais lub teeb liab wireless. Yog tias ob lub hauv paus chaw nres tsheb uas paub cov ntsiab lus tau txais lub teeb liab thiab qhov kev ncua deb ntawm lub cim thiab ob lub hauv paus chaw nres tsheb sib txawv, ces lub sij hawm cov ntsiab lus ntawm ob lub hauv paus chaw nres tsheb tau txais cov teeb liab sib txawv.
Lub teeb liab lub sij hawm raws li qhov chaw ua haujlwm, xws li UWB, yuav tsum tau rov ua haujlwm dua thaum lawv ntsib phab ntsa occlusion. Rau tib cheeb tsam, tus naj npawb ntawm chav yuav ob npaug, thiab kev siv lub hauv paus chaw nres tsheb yuav ob npaug. Nws yuav yooj yim dua rau kev xa cov chaw nres tsheb hauv qhov chaw qhib.
Cov kev lag luam tam sim no siv UWB qhov chaw siv thev naus laus zis yog qhov chaw, cov nroj tsuag tshuaj, tsev loj cuj, tsev kho mob, tsev laus, mines, thiab lwm yam lag luam.
Kev sib piv ntawm cheeb tsam cheeb tsam network positioning technology
Cov kev qhia saum toj no tau hais tseg raws li wireless hauv cheeb tsam hauv cheeb tsam network, ntawm lawv, ultra-wideband positioning system, qhov tseeb ntawm qhov chaw feem ntau mus txog centimeter-theem, tab sis xws li kev tso npe thov ntau yam me me, lub network yuav tsum tau rov ua dua, thiab cov neeg siv. yuav tsum tau siv cov cim qhia tshwj xeeb, cov cuab yeej ntsuas muaj tus nqi siv tau zoo. Txawm hais tias qhov tseeb ntawm lwm txoj kev tso npe yog me ntsis zuj zus, tus nqi kuj tseem qis dua. Feem ntau, lub teeb liab lub zog yog siv raws li kev siv.
Cov hom wireless hauv cheeb tsam network no feem ntau yog siv rau hauv qhov chaw sab hauv. Vim muaj kev cuam tshuam ntawm ib puag ncig sab hauv tsev, lub teeb liab txais lub zog yuav yooj yim hloov pauv. Nws yog ib qho nyuaj rau ua tiav qhov tseeb qhov chaw siv tsuas yog lub teeb liab lub zog.
Yog li ntawd, nyob ntawm qhov ntsuas qhov ntsuas, qhov chaw kuj tuaj yeem ua tiav siv txoj hauv kev raws li lub sijhawm tuaj txog ntawm lub teeb liab tau txais thiab ib txoj hauv kev raws li lub kaum sab xis tuaj txog ntawm lub teeb liab tau txais.
Peb lub thev naus laus zis ntawm Wi-Fi, Bluetooth thiab UWB, hais txog qhov tseeb ntawm qhov chaw, UWB tuaj yeem ncav cuag centimeter-level positioning, Bluetooth yog centimeter-to-meter level, thiab Wi-Fi tsuas yog meter-theem raug; Hais txog kev cuam tshuam, UWB yog qhov zoo dua li ob qho tib si; nyob rau hauv cov nqe lus ntawm kis tau tus mob nyob deb, Wi-Fi yog qhov deb tshaj plaws, UWB yog thib ob, thiab Bluetooth yog qhov luv tshaj; ntxiv rau; Hais txog tus nqi tsim kho, UWB cov nqi ntau dua li Wi-Fi thiab Bluetooth, Wi-Fi thiab Bluetooth muaj peev xwm cuam tshuam nrog niaj hnub smartphones zoo dua; Hais txog kev siv hluav taws xob, Bluetooth siv lub zog tsawg tshaj plaws, UWB yog thib ob, thiab Wi-Fi yog siab tshaj. Yog tias peb xav txog tag nrho cov xwm txheej no, Bluetooth zoo li yuav muaj lub sijhawm zoo los ua tus qauv tshiab hauv kev ua lag luam sab hauv tsev, thiab lwm yam thev naus laus zis yuav muaj lawv lub khw.
