Nkag siab seb rangefinders ua haujlwm li cas
Optical nrug meter
Optical rangefinders muab faib ua ob hom, theem hom rangefinders thiab mem tes rangefinders, raws li txoj kev ntsuas qhov deb.
Pulse rangefinder yog kev siv lub hom phiaj los tua lub teeb ntawm lub teeb, txiav txim siab lub hom phiaj yuav rov qab mus rau lub sijhawm ntawm lub teeb, thiaj li suav qhov kev ncua deb ntawm qhov ntsuas thiab lub hom phiaj, vim tias lub laser muaj qhov zoo. directionality, ib lub wavelength ib leeg, yog li nws yog photoelectric rangefinder feem ntau yog siv lub laser raws li cov khoom siv, yog li cov mem tes hom rangefinder kuj tseem hu ua laser rangefinder.
Siv cov txheej txheem pulse ntawm ntau yam laser rangefinder tuaj yeem ncav cuag ntau yam, tuaj yeem siv rau kev ntsuas sab hauv thiab sab nraum zoov, nws qhov ntev ntawm 3.5 meters txog 2000 meters, siab ntau laser rangefinder tuaj yeem ncav cuag 5000 meters, tub rog siv laser rangefinder tuaj yeem mus txog qhov deb dua. Raws li qhov muaj peev xwm los ntsuas qhov ntsuas qhov ntev ntawm lub hom phiaj, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom lub hom phiaj ntawm tus neeg siv, yog li lub laser rangefinder feem ntau muaj lub tshuab tsom iav, tseem hu ua laser rangefinder telescope, Daim duab 1 rau peb. -lub tog raj kheej laser rangefinder telescope ntawm daim duab raug.
Laser rangefinder qhov tseeb yog nyob ntawm qhov ntsuas los ntsuas lub laser muab tau txais lub sijhawm nruab nrab ntawm kev suav ntawm qhov tseeb, raws li kev siv tshuab thiab kev siv lub sijhawm laser rangefinder tuaj yeem muab faib ua qhov tseeb ntawm li 1 meter ntawm cov pa laser rangefinder (tsuas yog siv rau sab nraum zoov kev ua si, yos hav zoov, thiab lwm yam) thiab siv rau kev soj ntsuam thiab daim ntawv qhia, daim ntawv ntsuam xyuas av, kev tsim kho, kev siv engineering, kev ua tub rog thiab lwm lub sijhawm uas yuav tsum tau ua kom raug siab dua ntawm qhov tseeb ntawm hom laser rangefinder.
Phase method rangefinders yog rangefinders uas hloov cov theem ntawm lub laser thiab tau txais qhov kev ncua deb los ntawm kev ntsuas theem sib txawv ntawm lub laser reflected. Vim tias qhov yuav tsum tau xav txog rov qab mus rau lub laser theem kev tshawb pom, yog li cov kev xav tau ntawm cov teeb liab tau txais yuav tsum muaj kev siv zog, suav nrog kev nyab xeeb ntawm tib neeg lub qhov muag, yog li tsis tuaj yeem siv los ua lub tshuab hluav taws xob laser rangefinder telescope system. , thiab qhov ntau yog me me, xws li los ntawm ntau yam ntawm 0.5mm mus rau 150 meters, cov txheej txheem dav dav ntawm laser rangefinders siv 635nm (lub zeem muag rau liab) laser raws li cov khoom ntawm kev debugging, kuj paub. raws li lub infrared rangefinder. Feem ntau hu ua infrared rangefinder, tab sis qhov tseeb lub ntsiab lus ntawm lub laser tsis yog txhais los ntawm cov xim, thiab kev siv 635 nm laser rangefinder yog ncaj qha raug rau tib neeg lub qhov muag yuav ua rau irreversible kev puas tsuaj, thov nyeem kom raug siv thiab kev tiv thaiv.
Sonic Distance Ntsuas ntsuas
Kev ntsuas qhov deb ntawm acoustic yog siv lub suab tsis muaj qhov cuam tshuam thiab ntsuas qhov ntsuas, feem ntau siv ultrasonic tsis raws li cov khoom siv, uas yog, ultrasonic rangefinder. Ultrasonic transmitter mus rau ib qho kev taw qhia kom tso tawm ultrasonic tsis, nyob rau hauv lub tso tawm tib lub sij hawm pib lub sij hawm, ultrasonic tsis nyob rau hauv cov huab cua propagation, nyob rau hauv txoj kev kom tau raws li cov teeb meem yuav tam sim ntawd rov qab mus rau lub ultrasonic receiver kom tau txais lub reflected yoj tam sim ntawd cuam tshuam. kom nres lub sijhawm. Los ntawm kev tshawb pom cov nthwv dej uas cuam tshuam raws li qhov cuam tshuam tom qab nthwv dej tawm, lub sijhawm sib txawv T ntawm emitted ultrasonic nthwv dej thiab cov nthwv dej tau txais yog ntsuas, thiab tom qab ntawd qhov kev ncua deb L yog xam.
Vim lub ultrasonic propagation ceev nyob rau hauv cov huab cua los ntawm qhov kub thiab txias, av noo, huab cua siab, thiab lwm yam, yog li qhov kev ntsuas qhov yuam kev yog loj, thiab vim lub ultrasonic wavelength ntev, uas ua rau ib tug luv luv propagation nrug, yog li cov dav dav ultrasonic rangefinder ntsuas nrug. yog luv luv, qhov ntsuas qhov tseeb yog qhov tsawg. Tab sis kev siv ultrasound rau hauv cov kiv cua propagation yam ntxwv, nws qhov kev tshawb pom ntau yog loj dua qhov photoelectric rangefinder, nyob rau hauv qhov tseeb project yog dav siv nyob rau hauv kev ruaj ntseg, cable qhov siab ntsuas, obstacle nrhiav thiab lwm yam teb.
