Cov peev txheej ntawm kev ua yuam kev hauv photoelectric rangefinders
Qhov sib txawv qhov yuam kev ntawm photoelectric rangefinder tau muab faib ua ob ntu:
(1) Kev ua yuam kev loj: qhov yuam kev proportional rau qhov ntev ntawm qhov ntsuas qhov deb, feem ntau tshwm sim los ntawm qhov yuam kev zaus, atmospheric refractive index yuam kev, thiab lub tshuab nqus tsev ntsuas qhov yuam kev, ua rau muaj qhov yuam kev hauv qhov sib txawv. Qhov cuam tshuam ntawm kev ntsuas qhov yuam kev ntawm qhov ceev ntawm lub teeb ntawm tus nqi sib txawv tuaj yeem tsis quav ntsej.
(2) Kho qhov yuam kev: qhov kev ua yuam kev ntawm qhov ntsuas, ywj siab ntawm qhov ntev ntawm qhov ntsuas qhov deb, suav nrog calibration yuam kev ntawm xoom point yuam kev, alignment yuam kev ntawm lub ntsuas thiab lub reflector, theem ntsuas yuam kev, amplitude thiab theem yuam kev, theem tsis -uniformity yuam kev ntawm lub teeb-emitting raj, thiab periodic yuam kev. Lub sij hawm yuam kev feem ntau yog los ntawm tib zaus cuam tshuam ntawm cov teeb liab photoelectric sab hauv ntawm lub ntsuas, thiab qhov loj ntawm qhov yuam kev yog rov ua dua nyob rau hauv lub voj voog ntawm qhov ntev ntawm qhov ntsuas ntsuas ntsuas.
Ntawm lawv, proportional yuam kev, periodic yuam kev, thiab xoom yuam kev yog lub ntsiab systematic yuam kev ntawm lub photoelectric rangefinder.
Raws li ib tug loj npaum li cas ntawm cov ntaub ntawv ntsuas, nws yog pom tau hais tias vim lub theem tsis sib xws thiab amplitude thiab theem tsis ua hauj lwm ntawm lub ntsuas lub teeb-emitting thiab txais hlab, kuj muaj cov kev kho cov nqe lus hais txog nyob deb, ntxiv rau cov zaus yuam kev thiab atmospheric refractive index yuam kev. Kev lig kev cai, kev kho yam cuam tshuam txog kev ncua deb yog sib sau ua ke ua qhov sib npaug!. Qhov kev kho rau xoom point yuam kev yog hu ua additive tas li. Kev ua yuam kev tuaj yeem raug tshem tawm los ntawm kev siv cov kev kho rau qhov kev ua yuam kev ntawm qhov system uas tau txais thaum lub sij hawm calibration. Yog li ntawd, calibration ntawm lub system yuam kev ntawm photoelectric rangefinder feem ntau suav nrog peb yam hauv qab no:
(1) Kev txheeb xyuas qhov yuam kev raws sij hawm;
(2) Kev txheeb xyuas cov khoom ntxiv;
(3) Kev txheeb xyuas qhov sib npaug.
