Kev nkag siab zoo ntawm kev siv laser range finder
1. Kev faib tawm ntawm laser rangefinders
(1) Lub laser range finder yog muab faib ua ib tug handheld laser range finder thiab telescope laser range finder.
1. Handheld laser rangefinder: qhov ntsuas qhov deb feem ntau nyob hauv 200 meters, thiab qhov tseeb yog li 2 hli. Qhov no yog tam sim no feem ntau siv laser range finder. Functionally, ntxiv rau ntsuas qhov kev ncua deb, nws kuj tseem tuaj yeem xam qhov ntim ntawm cov khoom ntsuas.
2. Telescope-type laser range finder: qhov ntsuas qhov deb feem ntau yog li ntawm 600-3000 meters. Hom kab no muaj qhov ntsuas qhov ntev, tab sis qhov tseeb yog qhov tsawg, thiab qhov tseeb yog feem ntau txog 1 meter. Cov ntawv thov tseem ceeb yog kev ntsuas qhov ntev hauv thaj teb.
2. Cov teeb meem uas yuav tsum tau them sai sai rau thaum siv lub laser rangefinder
Kev ceev faj rau kev siv lub laser rangefinder:
① Lub laser rangefinder tsis tuaj yeem tsom ncaj qha rau tib neeg lub qhov muag rau kev ntsuas ncaj qha los tiv thaiv kev puas tsuaj rau tib neeg lub cev.
②Qhov dav dav laser ntau yam finder tsis yog dej tsis qab, yog li koj yuav tsum tau them sai sai rau cov dej tsis zoo.
③ Lub laser tsis muaj kev ua haujlwm ntawm kev tiv thaiv poob, yog li lub laser rangefinder yog ib qho yooj yim los ua txhaum lub teeb emitter.
Kev kho ntawm laser range finder:
① Nquag txheeb xyuas qhov zoo li ntawm cov cuab yeej thiab tshem tawm cov plua plav, roj, mildew, thiab lwm yam ntawm lub sijhawm.
②Thaum ntxuav lub qhov muag, lub hom phiaj lo ntsiab muag lossis lub qhov rai laser emission, siv cov ntaub mos muag. Nws yog nruj me ntsis txwv tsis pub khawb nrog cov khoom tawv, thiaj li tsis ua kom puas qhov kev ua haujlwm kho qhov muag.
③ Lub tshuab no yog cov cuab yeej ua haujlwm siab ua ke nrog lub teeb, tshuab thiab hluav taws xob. Nws yuav tsum tau ua tib zoo saib xyuas thaum siv. Nws yog nruj me ntsis txwv tsis pub nyem los yog poob ntawm qhov chaw siab kom tsis txhob muaj kev puas tsuaj rau lub ntsuas.
3. Laser range finder Muaj lus nug:
1. Lub hauv paus ntsiab lus ntawm kev siv infrared range lossis laser range yog dab tsi?
Lub hauv paus ntsiab lus ntawm qhov sib txawv tuaj yeem ua raws li ntsuas lub sijhawm xav tau rau lub teeb rov qab mus rau lub hom phiaj, thiab tom qab ntawd xam qhov deb D los ntawm qhov ceev ntawm lub teeb c=299792458m / s thiab atmospheric refraction coefficient n . Vim tias nws nyuaj rau ntsuas lub sijhawm ncaj qha, nws feem ntau yog ntsuas cov theem ntawm cov nthwv dej txuas ntxiv, uas yog hu ua theem ntsuas qhov ntsuas qhov ntsuas. Tau kawg, tseem muaj cov pulse range finders, feem ntau WILD's DI -3000. Nws yuav tsum raug sau tseg tias kev ntsuas theem tsis ntsuas theem ntawm infrared lossis laser, tab sis theem ntawm cov teeb liab hloov ntawm infrared lossis laser. Kev tsim kho kev lag luam muaj lub ntsuas hluav taws xob ntawm tes rau kev soj ntsuam hauv tsev uas ua haujlwm ntawm tib txoj cai.
2. Yuav tsum lub dav hlau ntawm cov khoom ntsuas yog perpendicular rau lub teeb?
Feem ntau precision ntsuas qhov deb yuav tsum muaj kev koom tes ntawm tag nrho cov kev xav ntawm prism, thaum lub rangefinder siv rau kev ntsuas hauv tsev ncaj qha ntsuas nrog cov phab ntsa du, feem ntau vim qhov kev ncua deb kuj luv thiab lub teeb liab lub zog ntawm lub teeb pom kev rov qab yog qhov loj txaus. Nws tuaj yeem paub los ntawm qhov no tias nws yuav tsum yog ntsug, txwv tsis pub lub teeb liab rov qab tsis muaj zog thiab qhov siab tshaj plaws tsis tuaj yeem tau txais.
3. Puas muaj peev xwm yog lub dav hlau ntawm cov khoom ntsuas yog diffuse reflection?
Nws yog feem ntau ua tau. Nyob rau hauv qhov tseeb engineering, ib tug nyias yas phaj yog siv raws li ib tug reflective nto los daws qhov teeb meem ntawm loj diffuse reflection.
4. Dab tsi yog qhov txawv ntawm ultrasonic ntau thiab laser sib txawv?
Ultrasonic ntau qhov tseeb yog qhov tsawg, thiab nws tsis tshua siv tam sim no. Qhov tseeb ntawm lub laser rangefinder tuaj yeem ncav cuag qhov yuam kev 1 hli, haum rau ntau yam kev ntsuas siab.
