Dab tsi yog lrf core core?

TusLaser Chancefinder(LRF) yog Marvel ntawm cov kev siv thev naus laus zis niaj hnub, kev siv cov ntawv thov kev tsim tawm thiab cov chaw tsim khoom thiab cov tsheb ntsuas. Tab sis koj puas tau xav tias dab tsi ua rau tus zuam siv lub zog no? Kev ua yeeb yam ntawm ib lrf - nws qhov ntau tshaj plaws, thiab kev ntseeg tau raws li kev seev cev tawv} yog ncaj qha seev cev ntawm nws sab hauv.
 

Tus txheej txheem ua haujlwm yooj yim ntawm LRF

Feem ntau lrfs ua haujlwm nyob rau qhov yooj yim tseem ceeb meej cov ntsiab cai hu ua"Lub sij hawm {- ntawm - davhlau" (TOF).

Qhov ntsuas emits yog luv luv, pom tsis tau ntawm txoj hlua laser ntawm lub hom phiaj.

Cov mem tes no mus rau lub hom phiaj, xav txog nws, thiab rov qab mus rau lub cuab yeej.

Ib qho Ultra -} precise timer ntsuas lub sijhawm, t, nws coj mus ncig ua si.

Siv cov ceev xwm txheej ntawm lub teeb, c, qhov kev ncua deb yog xam nrog cov qauv:Kev ncua deb=(c × t) / 2.

Ib qho yooj yim piv txwv yog qw ntawm lub hav cuam kawb thiab sijhawm ntev npaum li cas nws yuav siv lub ncha. Ib LRF ua qhov no nrog lub teeb, tsheej lab ntawm ib ob, thiab nrog qhov tseeb tshwm sim.

Lub tsib lub Cheebtsam tseem ceeb ntawm LRF piav qhia

Core Cheebtsam 1: Lub Tsev Laser Transmitter Chav - "lub qhov ncauj"

Chav tsev yog lub luag haujlwm rau kev tsim thiab npaj cov lej laser laser.

Laser Diode:Lub plawv ntawm lub transmitter, cov semiconductor tsim kom muaj kev sib koom ua kom lub teeb laser laser las. Feem ntau lrfs siv ze -} 905nm lossis lub qhov muag {{

Tsav Circuit Court:Qhov no muab ib qho muaj zog, meej, thiab instantaneous cov tes hluav taws xob rau lub laser diode, kom muaj kev sib xws thiab ntse laser ci ntsa iab.

Transmitter cov khoom siv (Collimating Lens):Lub lens no siv cov txheej txheem divergent lub teeb ci ntawm diode thiab duab nws mus rau hauv ib lub teeb nruj, tig mus rau thaum sib npaug. Qhov no qhia lub zog, tso cai rau kev taug kev mus ntev nrog kev kis tsawg.

Kev Cuam Tshuam:Lub laser lub zog loj thiab nqaj zoo ncaj qha txiav txim siab ntau tshaj plaws thiab muaj peev xwm ntau yam me me, cov khoom nyob deb.

Core tivthaiv 2: Chav Kho Kho Kom Zoo Optical - "Ob Qhov Muag"

Thaum lub teeb xa tawm xa cov teeb liab, tus txais txoj haujlwm yog mus ntes tus neeg hnov ​​qhov tsaus muag rov qab ncha.

Lub Hom Phiaj Lens (Lension Lens):Qhov loj - aperture lens uas ua zoo li lub teeb "lub teeb ci," sib sau ua ke ntau npaum li kev sib sau ua kom tau.

Voj hloov kho qhov muag lim:Ib qho chaw tseem ceeb sib xyaw ua ke ntawm lub ntsuas hluav taws xob. Nws yog tuned ciatsuasQhov tshwj xeeb yoj ntawm lub laser (piv txwv li, 905nm) kom dhau los ntawm, kev thaiv lub hnub ci, kev taug kev, thiab lwm lub suab nrov.

Photodetector (avalanche photodiode {{}}} aph):Nov yog qhov ua khawv koob ntawm kev hloov dua siab tshiab tshwm sim. Ib qho APD hloov siab dawb rau cov kev tsaus muag lub teeb rau hauv cov cim hluav taws xob tsis muaj zog. Nws cov ntsiab lus tseem ceeb yog "avalanche" nce - nws sab hauv lub teeb liab, ua rau nws muaj peev xwm tsawg heev.

Kev Cuam Tshuam:Qhov loj ntawm lub hom phiaj lens thiab qhov rhiab ntawm cov Apd yog qhov tseem ceeb rau kev ua tiav ntev ntev. Lub taub lim zoo dictates kev ua tau zoo hauv qhov kaj, hnub ci.

Cov Cheebtsam Muaj 3: Lub Siab - precision sij hawm - "stopwatch"

Nov yog lub paj hlwb tom qab qhov tseeb. Ntsuas lub sijhawm - ntawm- ya davhlau yuav tsum muaj qhov zoo kawg.

Lub sij hawm - rau - hack digital converter (TDC):Qhov tshwj xeeb ntawm Circuit Court yog lub siab - tech cheatwatch. Nws ntsuas lub sijhawm luv ntawm lub laser ntawm Laser Pulse thiab tshawb pom ntawm lub teeb liab rov qab los ntawm kev daws teeb meem hauv picoseconds lossis nanoseconds.

Kev Cuam Tshuam:Lub TDC qhov precision yog qhov txiav txim ncaj qha ntawm kev coj ua qhov tseeb. Lub sijhawm ua yuam kev ntawm ib qho Nanosecond txhais lus rau kev ncua deb ntawm txog 15 centimeters.

Qej Cheebtsam 4: Tswj & Teeb Meem Ua Ntej - Lub Hlwb "

Chav tsev no Orchestrates tag nrho cov haujlwm thiab ua rau kev nkag siab ntawm cov ntaub ntawv nyoos.

Microckontroller / digital teeb liab processor (DSP):Kev ua haujlwm ua nruab nrab ntawm LRF.

Teeb Liab Ua Circuital:Qhov no ua kom sov, cov ntxaij lim dej, thiab duab cov teeb liab tsis muaj zog thiab nrov hluav taws xob los ntawm Apd.

Cov paub tab tseem ceeb:

Xa cov lus hais kom ua rau lub laser tsav thiab ib txhij pib pib tdc.

Kev txheeb xyuas cov teeb liab kev ua kom pom tseeb txog qhov tseeb laser rov qab echo noj suab nrov.

Lim tawm tawm cov lus tsis tseeb (piv txwv li, los ntawm nag, plua plav, lossis noog).

Txib lub tdc nres rau cov phiajcim siv tau thiab ua tiav kev xam kev deb.

Core tivthaiv 5: Cov zaub & Cov Neeg Siv Khoom Siv interface - "lub ntsej muag"

Qhov no yog li cas tus neeg siv cuam tshuam nrog lub ntaus ntawv thiab tau txais cov ntaub ntawv.

Muab:Ib OLED lossis LCD npo uas qhia txog kev ntsuas ntsuas, hom, roj teeb muaj xwm txheej, thiab lwm cov ntaub ntawv.

Qhov muag daj / saib system:Hauv monocular -} style lrfs, qhov no yog lub zog ua kom zoo rau lub hom phiaj.

Tswj nyees khawm:Rau lub zog, hom kev xaiv, thiab pib ntsuas kev ntsuas.

Kev Cuam Tshuam:Chav tsev no txhais tau cov neeg siv kev paub dhau los ntawm kev pom meej, tus nqi kho tshiab, thiab siv tau yooj yim. Niaj hnub no lrfs feem ntau sib xyaw nrog cov solvers zoo nkauj, Bluetooth, thiab lwm yam ntawm no.

Yuav ua li cas cov tub ntxhais tseem ceeb ua haujlwm ua ke

Lub lag luam seamless ntawm LRF yog lub suab paj nruag ntawm kev sib koom tes:

Pib:Tus neeg siv nias lub pob. Chav tswj tau xa cov lus txib.

EMIT & pib moos:Lub Tsheb Tsav Hluav Taws Xob Cov Hluav Taws Xob Cov Hluav Taws Xob Lub Laser Diode, xa ib mem tes los ntawm lub tshuab xa khoom. Ib txhij, chav tswj hwm cov tdc kom pib sijhawm.

Tau Txais:Tus lej taw qhia yog sau los ntawm lub hom phiaj lens, lim los ntawm lub cim roj kho tshiab, thiab hloov dua siab tshiab rau hauv lub cim hluav taws xob los ntawm Aph.

Txheej Txheem & Ntes:Cov teeb liab ua cocuitalry ntxuav thiab ua kom pom cov teeb liab. Thaum cov khoom xa rov qab raug txheeb xyuas, nws ceeb toom cov chav tswj hwm.

Moos & xam:Cov kev tswj hwm cov lus txib lub TDC nres. Nws nyeem lub sijhawm T, thiab lub microcontroller xam qhov deb.

Muab:Qhov tshwm sim tau xa mus rau chav ua zaub rau tus neeg siv pom.

Xaus thiab Yav Tom Ntej Saib Xyuas

Hauv cov ntsiab lus, tsib lub Cheebtsam tseem ceeb ua ib qho system ua tiav: tusLaser xa khoomyog rab hmuv, tusKho qhov muag kho qhov muagyog daim ntaub thaiv npog, tusSijhawm timingyog tus kav, tusChav Tswjyog lub hlwb, thiab covQho sauyog lub qhov rais. Ua ke, lawv hloov kho lub cev nqaij daim tawv rau lub cev muaj zog, lub cuab yeej siv tau.

LRF Technology Sib Xws

Nti - nplai sib xyaw ua ke:Kev siv zog yog txoj kev nyob hauv kev sib sau ua ke laser, ntes, ua rau me me, pheej yig dua, thiab qis} fais fab khoom siv.

Sensor Fusion:LRFS tau nce zuj zus nrog GPS, Imus), koob yees duab), cov koob yees duab, thiab cua sov {{} dimension cov ntaub ntawv tshuab.

Txhim khu kev txawj ntse:Kev sib koom ua ke ntawm Ai yuav pab tau cov nta uas zoo li lub phiaj xwm tsis siv neeg, taug qab, thiab kev faib tawm, thiab ntau dua automonendous puas tau ua ntej.

Cov ntaub ntawv tiv toj:

Yog tias koj muaj tswv yim, xav tham nrog peb. Tsis hais qhov twg peb cov neeg yuav khoom yog thiab peb yuav tsum ua raws li peb lub hom phiaj los muab peb cov neeg siv khoom kom muaj txiaj ntsig zoo, tus nqi zoo tshaj plaws, thiab kev pabcuam zoo tshaj plaws.
