Ntse laser deb sensors pab cov chav dej ntse

Cov chav dej ntse hauv pej xeem yog cov neeg txawj ntse tshawb nrhiav thiab tswj cov tshuab uas tso siab rau hauv Internet + Internet of Things thev naus laus zis kom ua tiav ntau yam nyiaj ntsuab xws li kev taw qhia chav dej ntse, ntse saib xyuas ib puag ncig, kev siv hluav taws xob thiab cov cuab yeej txuas txuas, kev khiav hauj lwm thiab kev saib xyuas, uas tuaj yeem muab tau. zoo dua, ua tau zoo dua, kev pabcuam yooj yim thiab xis rau cov neeg siv chav dej.

01Ntse sensors los pab txhim kho cov chav dej ntse hauv pej xeem 

Nyob rau hauv cov nqe lus ntawm kev taw qhia chav dej ntse, kev siv cov ntse sensors tuaj yeem ntes covtag nrho ntws ntawm cov neeg caij tshebthiabsquatting muaj peev xwm,thiab ob cov ntaub ntawv no tuaj yeem siv los ntawm kev sib tham sib tham hauv cheeb tsam pej xeem, kom cov neeg siv chav dej thiab cov thawj coj tuaj yeem pom kev siv txhua lub rooj zaum tso quav rau txiv neej thiab poj niam, kev siv chav dej thib peb thiab niam thiab tus me nyuam chav, thiab txawm tias muab cov thawj coj nrog cov ntaub ntawv loj los kwv yees qhov ceev ntawm cov neeg khiav dej num thiab ua kom muaj kev tswj xyuas kev tu kom zoo.

Rau ob qho tag nrho cov chaw tso quav tso quav thiab squat nyob, peb tuaj yeem txhim kho qhov tseeb ntawm cov ntaub ntawv loj thiab txhim kho qhov kawg ntawm cov neeg siv kev paub nrog cov ntse sensors tshiab uas yog

tseeb duathiab muajtsawg kawg cuav zoo.

02 Kev sib piv ntawm kev ua haujlwm ntawm txhua lub sensor 

Tam sim no, feem ntau ntawm kev tshawb nrhiav squat siv cov tsoos ntse qhov rooj xauv lossis infrared sensors, thaum lub qhov rooj patronage nrhiav tau siv infrared sensors thiab 3D koob yees duab. Ib hom tshiab ntawm laser ntes, uas yog maj mam dhau los ua cov neeg siv khoom-qib hauv nqe thiab nthuav dav hauv daim ntawv thov, tuaj yeem ua tiav ob qho tib si squat nrhiav thiab patronage txheeb cais nrog qhov tseeb ntawm ntau dua 99%. Ntawm no yog ib qho piv txwv ntawm lub laser ntes los ntawm DianYingPu (R01 TSI) ua piv txwv, kev ua tau zoo ntawm ntau hom sensors feem ntau yog siv rau kev tshawb nrhiav squatting piv.

Table I. Kev soj ntsuam ntawm tag nrho qhov zoo thiab qhov tsis muaj zog ntawm kev ua haujlwm sensor

Txhawm rau txhim kho qhov tseeb ntawm kev tshawb nrhiav squat lossis cov neeg caij tsheb khiav kom pom, kev ua haujlwm siab sensors nrog kev ua haujlwm ruaj khov thiab qis qis qis qis yuav tsum muaj lub tswb nrov. CovHauv qab no yog kev sib piv ntawm ntau qhov kev ua tau zoo ntawm ntau lub infra-red sensors thiab DianYingPu R01Lidar sensors.

Ntsuas deb

Hauv cov nroog tshiab lossis kho dua tshiab, thaj chaw zoo nkauj, txoj kev loj, tshav dav hlau thiab lwm lub sijhawm ntawm cov chav dej ntse ntse, nrog R01Lidar sensorsTxhawm rau kom ua tiav qhov kev tshawb nrhiav squatting thiab cov neeg caij tsheb khiav cov ntaub ntawv muaj nuj nqi, yuav tsis raug rau cov tsoos infrared sensor installation qhov siab txwv (tseem ceeb infrared sensor xav tau lub installation qhov siab nyob rau hauv 2m, sab hauv tsev tsis muaj zog ambient teeb meem).

R01Lidar sensorsKev sim ua ntej ntawm cov khoom sib txawv xim, nrog rau cov khoom xim tsaus, mus txog qhov deb ntawm ntau tshaj 3 meters.Pa infrared sensors tsuas ntsuas txog li 1 meter. 

B.Qhov tseebntawm kev ntsuas

Thaum siv cov chav dej hauv tsev, qhov sib txawv ntawm cov neeg siv khoom siab, khaub ncaws thiab khoom siv tuaj yeem ua rau muaj kev hloov pauv ntawm qhov kev ncua deb ntawm lub sensor vim muaj qhov sib txawv, uas yuav ntsuas qhov tseeb ntawm qhov ntsuas qhov ntsuas qhov deb, piv txwv li qhov yuam kev tus nqi.

Cov duab saum toj no siv qhov ntsuas qhov tseeb hauv tsev siv cov thawv ntawv tiaj tus, kab rov tav axis yog tus qauv kev ncua deb, ntsug axis yog qhov yuam kev deb,kuaj cov npe sib txawv ntawm LiDAR sensors,los ntawm cov ntaub ntawv hloov pauv qhov xwm txheej, lublwm yam 4 hom nyob rau hauv lub 3m range sensoryuam kevmuajzoo fluctuation,hom 1, 2, 4 txawm tias los ntawm 260cm mus ntxiv tsis tuaj yeem kuaj cov ntaub ntawv. CovR01LIDAR, ntawm qhov tod tes, yuav luag tsis muaj qhov yuam kev hauv qhov3m qhov siab,nrog aQhov siab tshaj plaws yog 440 cm. 

Xav tias qhov xwm txheej hnyav heev tab sis muaj peev xwm ua tau: tus me nyuam tsuas yog 1m hauv qhov siab, lub ntsuas hluav taws xob tau teeb tsa ntawm qhov siab ntawm 2.6m, tus menyuam tuaj yeem txav nws lub cev rov qab mus rau tom qab squatting, qhov ntsuas ntau yog nyob rau hauv thaj tsam ntawm 1.9-2.1. m, yog hais tias cov ntaub ntawv ntsuas los ntawm lub sensor fluctuates heev, qhov tshwm sim ntawm lub tswb cuav yuav dhau los ua siab, cuam tshuam rau cov neeg siv khoom kom yuam kev txog squatting margin.
