Kev saib xyuas niaj hnub thiab cov qauv ntawm laser rangefinders
Optical rangefinder txij nkawm:
① feem ntau tshawb xyuas qhov zoo li ntawm cov cuab yeej raws sij hawm kom tshem tawm cov plua plav thiab av, roj, pwm 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 siv tawv tawv khawb, thiaj li tsis ua rau cov khoom siv kho qhov muag puas.
③ Lub tshuab no yog ib qho khoom siv 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 los yog ntog los ntawm qhov chaw siab, thiaj li tsis ua rau cov twj paj nruag puas.
Cov teeb meem yuav tsum tau sau tseg thaum siv: 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. Yog li qhov kom zoo dua ntawm cov khoom tsim ntawm qhov chaw uas tuaj yeem ua dej tsis zoo thiab tiv thaiv huab cua, nruab nrog cov ceg ntoo hav zoov thiab nplooj coated nrog 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.
1. Muaj peev xwm ntsuas cov khoom dav hlau rau diffuse reflection
Feem ntau kuj tuaj yeem siv tau, qhov project tiag tiag yuav siv lub phaj yas nyias los ua ib qho kev cuam tshuam 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 ua tiav raws li qhov ntsuas ntawm lub teeb mus ncig lub sijhawm mus rau lub hom phiaj, thiab tom qab ntawd los ntawm qhov ceev ntawm lub teeb c=299792458m / s thiab atmospheric refraction coefficient n los xam qhov deb D. Vim qhov nyuaj ntawm kev ntsuas ncaj qha ntawm lub sijhawm, feem ntau txiav txim siab theem ntawm cov nthwv dej txuas ntxiv, hu ua phasor rangefinder. Tau kawg, kuj tseem muaj cov ntsuas ntsuas pulse, 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 tes tuav laser rangefinder rau kev ntsuas vaj tsev, uas ua haujlwm ntawm tib txoj cai.
3. Laser rangefinder qhov tseeb tuaj yeem ncav cuag 1 millimeter yuam kev, haum rau ntau hom kev ntsuas siab.
Laser rangefinder yuav tsum tau them sai sai rau kev siv qhov teeb meem: laser rangefinder tsis tuaj yeem tsom rau tib neeg lub 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 lub tebchaws United States hauv zos feem ntau yog rau sab nraum zoov shou yos hav zoov enthusiasts, yog li qhov kom zoo dua ntawm ua qhov chaw uas yuav waterproof tiv thaiv pos huab, nruab nrog zoov nuj txeeg 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, kev siv tsawg dua.
