Hauv cov teb xws li drone obstacle zam, muaj automation, ntse kev ruaj ntseg, thiab robotic navigation, laser rangefinder modules tau dhau los ua qhov tseem ceeb ntawm cov khoom tseem ceeb vim lawv qhov siab precision thiab ceev teb. Txawm li cas los xij, laser kev nyab xeeb tseem yog ib qho kev txhawj xeeb tseem ceeb rau cov neeg siv - peb yuav ua li cas kom ntseeg tau tias laser rangefinder modules ua haujlwm tau zoo thaum ua raws li kev tiv thaiv qhov muag thiab cov qauv kev nyab xeeb ib puag ncig? Kab lus no muab kev tshuaj xyuas qhov tob ntawm laser rangefinder module kev nyab xeeb kev faib tawm, cov ntawv pov thawj thoob ntiaj teb, thiab cov lus pom zoo xaiv los pab koj xaiv kev nyab xeeb dua thiab ua raws li kev xaiv.
1. Laser Safety Levels: Qhov txawv ntawm Chav Kawm I mus rau Chav Kawm IV
Raws li IEC 60825-1 tus qauv muab los ntawm International Electrotechnical Commission (IEC), cov khoom siv laser raug faib ua Class I mus rau Class IV, nrog cov chav kawm siab dua qhia tias muaj kev pheej hmoo ntau dua. Rau laser rangefinder modules, cov kev faib feem ntau yog Class 1, Class 1M, Class 2, thiab Class 2M. Lub ntsiab sib txawv yog raws li nram no:
| Qib kev nyab xeeb | Cov zis siab tshaj plaws | Risk Description | Hom Daim Ntawv Thov Scenarios |
| Chav Kawm 1 | <0.39mW (pom lub teeb) | Tsis muaj kev pheej hmoo, tsis muaj kev tiv thaiv kev tiv thaiv | Cov khoom siv hluav taws xob, khoom siv kho mob |
| Chav Kawm 1M | <0.39mW (pom lub teeb) | Tsis txhob saib ncaj qha los ntawm cov cuab yeej kho qhov muag | Muaj ntau yam, automotive LiDAR |
| Chav kawm 2 | <1mW (lub teeb pom kev) | Kev raug luv luv (<0.25 vib nas this) muaj kev nyab xeeb | Handheld rangefinders, saib xyuas kev ruaj ntseg |
| Chav Kawm 2M | <1mW (lub teeb pom kev) | Tsis txhob saib ncaj qha los ntawm cov cuab yeej kho qhov muag lossis lub sijhawm ntev | Sab nraum zoov kev soj ntsuam, drone obstacle zam |
Key Takeaway:
Chav Kawm 1/1M yog tus qauv kub rau qib kev lag luam laser rangefinder modules, ua kom "qhov muag tsis pom kev" ua haujlwm nyob rau hauv ib puag ncig nyuaj. Chav kawm 3 thiab saum toj no lasers yuav tsum tau siv cov kev txwv nruj thiab feem ntau tsis haum rau pej xeem lossis qhib ib puag ncig.
2. Cov ntawv pov thawj thoob ntiaj teb: Ib qho Kev Xav Tau Zoo rau Kev Ua Raws Cai
Txhawm rau nkag mus rau hauv lub ntiaj teb kev lag luam, laser rangefinder modules yuav tsum ua raws li qhov yuav tsum tau muaj ntawv pov thawj kev nyab xeeb ntawm lub hom phiaj lub teb chaws / cheeb tsam. Ob tug qauv tseem ceeb yog:
① IEC 60825 (International Standard)
Npog EU, Asia, thiab lwm thaj chaw. Cov neeg tsim khoom yuav tsum muab daim ntawv qhia txog kev nyab xeeb ntawm cov hluav taws xob laser tag.
Daim ntawv pov thawj tsom rau qhov ntau yam wavelength, tso zis zog, beam divergence lub kaum ntse ntse, thiab kev tiv thaiv tsim.
② FDA 21 CFR 1040.10 (Tebchaws Asmeskas Kev Lag Luam)
US Food and Drug Administration (FDA) faib cov lasers zoo ib yam li IEC tab sis xav tau cov ntawv ceeb toom ntxiv xws li "DANGER" lossis "CAUTION".
Rau lub tsheb LiDAR xa tawm mus rau Tebchaws Meskas, ua raws li SAE J1455 (tsheb-qib vibration thiab kub-humidity qauv) kuj yuav tsum tau..
Peb lub tuam txhab lub laser rangefinder modules yog tag nrho CE, FCC, RoHS, thiab FDA tau ntawv pov thawj thiab tuaj nrog ua tiav cov ntaub ntawv xeem, kom ntseeg tau tias cov khoom xa tuaj thoob ntiaj teb.
3. Yuav Ua Li Cas Xaiv Qhov Kev Nyab Xeeb Zoo? Scene-Based Xaiv Phau Ntawv Qhia
① Consumer Electronics & Home Use
Qib pom zoo: Chav 1
Yog vim li cas: Ua tiav tshem tawm cov kev pheej hmoo ntawm cov neeg siv tsis raug, ua rau nws zoo tagnrho rau cov khoom siv ze-rau-lub cev xws li tshuab nqus tsev neeg hlau thiab cov tshuab ntse hauv tsev.
② Muaj Automation & AGV Navigation
Pom zoo Qib: Chav Kawm 1M
Yog vim li cas: Muaj zog tsis kam mus rau ambient teeb cuam tshuam, thaum kho qhov muag tsim tiv thaiv ncaj qha laser raug.
③ Kev Tshawb Fawb Sab Nraud & Kev Tsim Kho Machinery
Pom zoo Qib: Chav 2M
Yog vim li cas: Sib npaug precision thiab kev nyab xeeb nyob rau hauv qhov ntev (50-1000m) rangefinding, yuav tsum tau ntxiv kev ruaj ntseg daim ntawv lo.
4. Xaus
Qib kev nyab xeeb ntawm lub laser rangefinder module tsis yog hais txog kev ua raws li - nws kuj yog ib qho tseem ceeb ntawm kev koom tes hauv zej zog. Xaiv cov ntawv pov thawj thoob ntiaj teb Chav Kawm 1/1M cov khoom uas haum rau daim ntawv thov scenario txo qhov kev pheej hmoo thiab ua kom lub sijhawm ntev, ruaj khov ntawm cov khoom siv.
