Qhov chaw sab hauv tsev tuaj yeem suav hais tias yog thaj chaw dawb huv rau kev siv, thiab tsis muaj cov cuab yeej tsim nyog kom ua tiav qhov haujlwm no. GPS teeb liab sab hauv tsev tsis zoo, thiab RSSI qhov chaw raug txwv los ntawm qhov raug thiab ntau yam, thiab nws nyuaj rau muab cov kev pabcuam txaus siab. Kev tso tawm tsis ntev los no ntawm Bluetooth 5.1 tau coj cov kev taw qhia tshiab-nrhiav muaj nuj nqi, uas muaj peev xwm muab centimeter-level positioning raug, thiab muab ib tug txhim khu kev qha kev daws teeb meem rau sab hauv tsev.
Yuav ua li cas ua tiav qhov "centimeter-theem" qhov chaw ntawm Bluetooth 5.1?
Tom qab kev taw qhia ntawm Kev Taw Qhia Nrhiav hauv Bluetooth 5.1 cov ntsiab lus tseem ceeb, qhov tseeb ntawm qhov chaw ntawm Bluetooth tuaj yeem ua kom zoo rau "centimeter-level". Qhov no yog vim hais tias cov kev taw qhia-nrhiav muaj nuj nqi ntawm Bluetooth 5.1 yog tsuas yog tsim los ntawm ob lub ntsiab lus, uas yog lub AoA (Lub kaum sab xis ntawm tuaj txog) thiab AoD (Lub kaum sab xis ntawm kev tawm mus).
AoA yog cov txheej txheem kom tau txais lub azimuth thiab qhov deb ntawm lub transmitter thiab tus txais los ntawm triangulation los ntawm kev sim cov kev taw qhia ntawm kev tuaj txog ntawm cov teeb liab mus rau lub receiver, feem ntau yog rau RTLS (lub sij hawm qhov chaw nyob qhov system), cov khoom taug qab thiab cov ntaub ntawv tseem ceeb. Cov cuab yeej qhia tau siv ib lub kav hlau txais xov kom xa cov pob ntawv tshwj xeeb ntawm kev taw qhia-nrhiav, thiab cov khoom tau txais muaj ntau lub kav hlau txais xov. Cov kav hlau txais xov sib txawv ntawm cov cuab yeej txais yuav muaj lub sijhawm me me offset thaum tau txais cov lus qhia-nrhiav pob khoom ntawm cov khoom siv. Qhov kev hloov pauv theem no tshwm sim los ntawm sab pob ntawv teeb liab ntawm cov khoom siv kav hlau txais xov yog hu ua IQ cov qauv ntawm lub teeb liab. Tom qab ntawd txheeb xyuas tus nqi IQ kom tau txais cov ntaub ntawv sib koom ua ke ntawm lub cuab yeej yuav tsum nyob.
Yuav Ua Li Cas Bluetooth 5.1 Siv Centimeter-Level Positioning
AoD tseem yog kev siv lub teeb liab theem sib txawv technology, nws triangulation yog ua los ntawm kev ntsuam xyuas cov kev taw qhia ntawm kev tawm ntawm cov teeb liab kis tau los ntawm lub transmitter, feem ntau yog rau sab hauv tsev qhov chaw. Qhov kev taw qhia-nrhiav thev naus laus zis no tsim nyog rau kev tswj cov khoom hauv tsev, kev xa khoom, thiab kev cia khoom. Tus tswv tsev tso npe xa cov pob ntawv qhia kev taw qhia los ntawm ntau lub kav hlau txais xov array, thiab cov cuab yeej tso chaw tau txais cov pob ntawv qhia kev nrhiav thiab suav cov kev sib koom ua ke ntawm cov khoom siv los ntawm kev ua piv txwv thiab kev tsom xam ntawm IQ qhov tseem ceeb.
Yuav Ua Li Cas Bluetooth 5.1 Siv Centimeter-Level Positioning
Kev sib txuas ntawm AoA thiab AoD txoj hauv kev, qhov tseeb ntawm Bluetooth 5.1 tau mus txog qib centimeter, thiab tuaj yeem ua tiav qhov chaw 3D sab hauv.
Puas yog tsab xov xwm no qhia koj tawm ntawm qhov tsis zoo ntawm Bluetooth 5.1 li cas siv centimeter-theem positioning? Yog tias tsis yog, tsis txhob yig tiv tauj Feasycom kom paub ntau ntxiv.
