Lub hauv paus ntawm kev ua yuam kev rau photoelectric rangefinders
Qhov kev ua yuam kev ntawm qhov ntsuas qhov deb ntawm optoelectronic tau muab faib ua ob ntu:
(1) Qhov yuam kev: Qhov yuam kev uas yog 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 lub teeb nrawm ntsuas qhov yuam kev. Kev cuam tshuam ntawm qhov yuam kev hauv kev ntsuas qhov nrawm ntawm lub teeb ntawm qhov sib txawv ntawm tus nqi 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 sab hauv photoelectric ntawm qhov ntsuas, thiab qhov loj ntawm qhov yuam kev yog rov ua dua nyob rau hauv lub voj voog ntawm qhov ntev ntawm qhov ntsuas qhov ntsuas.
Ntawm lawv, kev faib ua feem yuam kev, lub sij hawm yuam kev, thiab xoom yuam kev yog lub ntsiab system yuam kev ntawm lub photoelectric nrug ntsuas ntsuas.
Raws li qhov loj ntawm cov ntaub ntawv ntsuas, nws tau pom tias vim muaj cov yam ntxwv xws li theem tsis sib xws thiab theem amplitude yuam kev ntawm qhov ntsuas lub teeb-emitting thiab txais cov raj, kuj tseem muaj cov ntsiab lus kho uas cuam tshuam txog qhov ntev ntawm qhov sib ntxiv ntawm qhov yuam kev. thiab atmospheric refractive index yuam kev. Kev lig kev cai, kev kho tus lej cuam tshuam txog qhov ntev ntawm qhov kev ncua deb tau sau ua ke los ua qhov sib npaug!. Qhov kev kho rau xoom point yuam kev yog hu ua additive tas li. Qhov 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, lub calibration ntawm lub system yuam kev ntawm lub photoelectric nrug ntsuas ntsuas feem ntau muaj xws li cov nram qab no peb yam:
(1) Kev txheeb xyuas qhov yuam kev raws sij hawm;
(2) Kev txheeb xyuas cov khoom ntxiv;
(3) Kev txheeb xyuas qhov sib npaug.
