Kev saib xyuas niaj hnub thiab cov qauv ntawm laser rangefinding
Optical rangefinder txij nkawm:
① feem ntau tshawb xyuas qhov zoo li ntawm cov cuab yeej hauv lub sijhawm kom tshem tawm cov plua plav thiab av, roj, mildew, thiab lwm yam.
② Ntxuav lub qhov muag, lub hom phiaj lo ntsiab muag lossis lub qhov rai laser emission yuav tsum siv cov ntaub mos muag. nruj me ntsis txwv tsis pub siv cov khoom tawv, thiaj li tsis ua kom cov khoom kho qhov muag puas.
③ Lub tshuab no yog lub tshuab kho qhov muag, tshuab thiab hluav taws xob sib xyaw ua ke ntawm cov cuab yeej ua haujlwm siab, kev siv uas yuav tsum tau ua tib zoo thiab maj mam muab tso, thiab nruj me ntsis txwv tsis pub extrusion lossis ntog los ntawm qhov siab, kom tsis txhob muaj kev puas tsuaj rau lub ntsuas.
Cov teeb meem xav tau kev saib xyuas thaum siv: laser rangefinder tsis tuaj yeem tsom rau tib neeg qhov muag ncaj qha ntsuas, tiv thaiv kev puas tsuaj rau tib neeg lub cev. Nyob rau tib lub sij hawm, lub vibration meter dav dav laser rangefinder tsis muaj dej tsis muaj dej, yog li koj yuav tsum tau them sai sai rau cov dej tsis zoo. Yog li qhov kom zoo dua ntawm qhov chaw tsim khoom uas tuaj yeem ua kom tsis muaj dej tsis zoo thiab fogproof, nruab nrog cov ceg ntoo hav zoov thiab nplooj pleev xim rau xim.
Lub laser tsis muaj kev ua haujlwm ntawm kev tiv thaiv poob, yog li lub laser rangefinder yog ib qho yooj yim los poob lub luminescent ntaus ntawv.
Txoj Cai
1. Muaj peev xwm ntsuas cov khoom dav hlau rau diffuse reflection
Feem ntau kuj tuaj yeem siv tau, qhov tseeb engineering yuav raug siv los ua ib lub phaj yas nyias nyias los daws qhov teeb meem ntawm kev cuam tshuam loj heev.
2. Kev siv infrared ntau yam lossis laser ranging txoj cai
Lub hauv paus ntsiab lus ntawm kev ntsuas qhov deb tuaj yeem txo qis los ntsuas lub sij hawm xav tau rau lub teeb mus rau thiab los ntawm lub hom phiaj, thiab tom qab ntawd los ntawm qhov ceev ntawm lub teeb c=299792458m / s thiab atmospheric refraction coefficient n los xam cov nrug D. Vim yog qhov nyuaj ntawm kev ntsuas lub sij hawm ncaj qha, nws feem ntau yog txiav txim siab los ntawm theem ntawm cov nthwv dej tsis tu ncua, hu ua phasor rangefinder. Tau kawg, kuj tseem muaj cov ntsuas pulsefinders, feem ntau WILD's DI-3000.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias phasorimetry tsis ntsuas cov theem ntawm infrared lossis laser, tab sis theej cov theem ntawm cov teeb liab modulated nyob rau sab saum toj ntawm infrared lossis laser. Kev tsim kho kev lag luam muaj ib tug handheld laser rangefinder rau kev ntsuas vaj tse, uas ua haujlwm ntawm tib txoj cai.
3. Laser rangefinder qhov tseeb tuaj yeem ncav cuag 1 hli yuam kev, haum rau ntau hom kev ntsuas siab.
Laser rangefinders yuav tsum tau them sai sai rau kev siv qhov teeb meem: laser rangefinders tsis tuaj yeem tsom rau tib neeg qhov muag ncaj qha ntsuas, tiv thaiv kev puas tsuaj rau tib neeg lub cev. Nyob rau tib lub sij hawm, lub vibration meter dav dav laser rangefinder tsis muaj dej tsis muaj dej, yog li koj yuav tsum tau them sai sai rau cov dej tsis zoo. Teb Chaws Asmeskas Rio Porter laser rangefinder, vim yog lub tebchaws United States feem ntau rau sab nraum zoov shou yos hav zoov enthusiasts, yog li qhov zoo ntawm kev ua qhov chaw yog waterproof thiab fogproof, nrog hav zoov ntoo ceg thiab nplooj pleev xim rau xim.
4. Lub dav hlau ntawm cov khoom ntsuas yuav tsum yog perpendicular rau lub teeb.
Feem ntau qhov kev txiav txim siab yuav tsum tau ua kom muaj kev cuam tshuam prisms nrog lub tsev ntsuas nrog lub rangefinder, ncaj qha mus rau qhov kev ntsuas ntawm phab ntsa du, feem ntau vim tias qhov kev ncua deb yog ze, lub teeb pom kev rov qab mus rau lub teeb liab lub zog loj txaus. Nrog rau qhov no tuaj yeem paub, yuav tsum yog ntsug, txwv tsis pub lub teeb liab rov qab tsis muaj zog heev yuav tsis tuaj yeem tau txais qhov kev ncua deb.
5. Ultrasonic ntau qhov tseeb yog qhov tsawg, siv tsawg dua.
