01 Isingeniso
I-Laser uhlobo lokukhanya olukhiqizwa yimisebe evuselelwe yama-athomu, ngakho-ke ibizwa ngokuthi “i-laser”. Idunyiswa njengenye into esungulwe kakhulu esintwini ngemuva kwamandla enuzi, amakhompyutha kanye nama-semiconductor kusukela ngekhulu lama-20. Ibizwa ngokuthi “ummese osheshayo”, “umbusi onembe kakhulu” kanye “nokukhanya okugqamile”. I-laser rangefinder iyithuluzi elisebenzisa i-laser ukukala ibanga. Ngokuthuthuka kobuchwepheshe bokusetshenziswa kwe-laser, i-laser ranging isetshenziswe kabanzi ekwakhiweni kobunjiniyela, ukuqapha kwe-geological kanye nemishini yezempi. Eminyakeni yamuva nje, ukuhlanganiswa okwandayo kobuchwepheshe be-laser semiconductor obusebenza kahle kakhulu kanye nobuchwepheshe bokuhlanganiswa kwesekethe enkulu kukhuthaze ukwenziwa kube kuncane kwamadivayisi e-laser ranging.
02 Isingeniso Somkhiqizo
I-LSP-LRD-01204 semiconductor laser rangefinder iwumkhiqizo omusha othuthukiswe ngokucophelela yiLumispot ohlanganisa ubuchwepheshe obuthuthukisiwe kanye nomklamo owenziwe umuntu. Lo modeli usebenzisa i-diode ye-laser engu-905nm ehlukile njengomthombo wokukhanya oyinhloko, ongagcini nje ngokuqinisekisa ukuphepha kwamehlo, kodwa futhi usetha izinga elisha emkhakheni we-laser rangeing ngokuguqulwa kwayo kwamandla okuphumelelayo kanye nezici zokukhipha ezizinzile. Ifakwe ama-chip asebenza kahle kakhulu nama-algorithms athuthukile athuthukiswe ngokuzimela yiLumispot, i-LSP-LRD-01204 ifinyelela ukusebenza okuhle kakhulu ngokuphila isikhathi eside kanye nokusetshenziswa kwamandla aphansi, ihlangabezana kahle nesidingo semakethe semishini yokulinganisa enembile kakhulu, ephathekayo.
Umfanekiso 1. Umdwebo womkhiqizo we-LSP-LRD-01204 semiconductor laser rangefinder kanye nokuqhathaniswa kosayizi nohlamvu lwemali lwe-yuan eyodwa
03 Izici Zomkhiqizo
*I-algorithm yokunxephezela idatha esezingeni eliphezulu ngokunemba okuphezulu: i-algorithm yokwenza ngcono, ukulinganisa okuhle
Ekufuneni ukunemba kokulinganisa ibanga okuphelele, i-LSP-LRD-01204 semiconductor laser rangefinder isebenzisa ngendlela entsha i-algorithm yokulinganisa ibanga ethuthukisiwe, ekhiqiza ijika eliqondile lokulinganisa idatha ngokuhlanganisa imodeli yezibalo eyinkimbinkimbi nedatha elinganisiwe. Lokhu kuthuthukiswa kobuchwepheshe kwenza i-rangefinder yenze ukulungiswa kwesikhathi sangempela nokunembile kwamaphutha enkambisweni yokulinganisa ibanga ngaphansi kwezimo ezahlukahlukene zemvelo, ngaleyo ndlela ifinyelele ukusebenza okuhle kakhulu ngokunemba kokulinganisa ibanga eliphelele ngaphakathi kwemitha eli-1 kanye nokunemba kokulinganisa ibanga eliseduze kwemitha eli-0.1.
*Lungiselelaindlela yokulinganisa ibanga: ukulinganisa okunembile ukuthuthukisa ukunemba kokulinganisa ibanga
I-laser rangefinder isebenzisa indlela yokuphindaphinda imvamisa ephezulu. Ngokuqhubeka nokukhipha ama-laser pulses amaningi nokuqoqa nokucubungula izimpawu ze-echo, icindezela ngempumelelo umsindo nokuphazamiseka futhi ithuthukise isilinganiso sesignali kuya komsindo sesignali. Ngokwenza ngcono ukwakheka kwendlela yokukhanya kanye ne-algorithm yokucubungula izimpawu, ukuzinza nokunemba kwemiphumela yokulinganisa kuyaqinisekiswa. Le ndlela ingafinyelela ukulinganisa okunembile kwebanga eliqondiwe futhi iqinisekise ukunemba nokuqina kwemiphumela yokulinganisa ngisho naphezu kwezimo eziyinkimbinkimbi noma izinguquko ezincane.
*Umklamo wamandla aphansi: ukusebenza kahle, okonga amandla, nokusebenza kahle
Lobu buchwepheshe buthatha ukuphathwa kokusetshenziswa kwamandla okuphezulu njengengqikithi yabo, futhi ngokulawula kahle ukusetshenziswa kwamandla kwezingxenye ezibalulekile njengebhodi lokulawula eliyinhloko, ibhodi lokushayela, ibhodi le-laser kanye nebhodi le-amplifier yokwamukela, kufinyelela ekunciphiseni okukhulu ebangeni eliphelele ngaphandle kokuthinta ibanga lokuhamba kanye nokunemba. Ukusetshenziswa kwamandla ohlelweni. Lo mklamo wamandla aphansi awubonisi nje kuphela ukuzibophezela kwawo ekuvikelweni kwemvelo, kodwa futhi uthuthukisa kakhulu umnotho kanye nokusimama kwemishini, ube yingqophamlando ebalulekile ekukhuthazeni intuthuko eluhlaza yobuchwepheshe bokuhamba.
*Amandla okusebenza ngokweqile: ukushabalalisa ukushisa okuhle kakhulu, ukusebenza okuqinisekisiwe
I-laser rangefinder ye-LSP-LRD-01204 ibonise ukusebenza okumangalisayo ngaphansi kwezimo zokusebenza ezimbi kakhulu ngomklamo wayo omuhle kakhulu wokusabalalisa ukushisa kanye nenqubo yokukhiqiza ezinzile. Ngenkathi iqinisekisa ukutholakala kwebanga eliqondile kanye nebanga elide, umkhiqizo ungamelana namazinga okushisa aphezulu endaweni yokusebenza afinyelela ku-65°C, okubonisa ukuthembeka kwawo okuphezulu kanye nokuqina kwawo ezindaweni ezinzima.
*Idizayini encane, kulula ukuyiphatha
I-laser rangefinder ye-LSP-LRD-01204 isebenzisa umqondo womklamo omncane othuthukisiwe, ihlanganisa uhlelo lokukhanya olunembile kanye nezingxenye ze-elekthronikhi emzimbeni olula onesisindo esingamagremu ayi-11 kuphela. Lo mklamo awuthuthukisi nje kuphela ukuthwaleka komkhiqizo, okuvumela abasebenzisi ukuthi bawuthwale kalula ephaketheni noma esikhwameni, kodwa futhi wenza kube lula futhi kube lula ukuwusebenzisa ezindaweni eziyinkimbinkimbi nezishintshashintshayo zangaphandle noma ezindaweni ezincane.
04 Isimo Sesicelo
Kusetshenziswa kuma-UAV, izindawo zokubona, imikhiqizo yangaphandle ephathwa ngesandla kanye neminye imikhakha yesicelo ehlukahlukene (izindiza, amaphoyisa, izitimela, ugesi, ukugcinwa kwamanzi, ezokuxhumana, imvelo, i-geology, ukwakhiwa, iminyango yomlilo, ukuqhuma, ezolimo, amahlathi, ezemidlalo zangaphandle, njll.).

06 Iziqondiso
- I-laser ekhishwa yile module ejikelezayo ingu-905nm, okuphephile emehlweni abantu. Kodwa-ke, kunconywa ukuthi ungabheki ngqo ku-laser.
- Le module yokujikeleza ayingeni moya. Qiniseka ukuthi umswakama wendawo yokusebenza ungaphansi kuka-70% futhi ugcine indawo yokusebenza ihlanzekile ukuze ugweme ukulimaza i-laser.
- i-ranging module ihlobene nokubonakala komoya kanye nohlobo lwe-target. Ibanga lizoncishiswa ezimweni zenkungu, imvula kanye nesiphepho sesihlabathi. Ama-target afana namaqabunga aluhlaza, izindonga ezimhlophe, kanye ne-limestone eveziwe anokukhanya okuhle futhi angandisa ibanga. Ngaphezu kwalokho, lapho i-angle yokuthambekela kwe-target ku-laser beam ikhula, ibanga lizoncishiswa.
- Akuvunyelwe ngokuphelele ukuxhuma noma ukukhipha ikhebula uma ugesi uvuliwe; qiniseka ukuthi i-polarity yamandla ixhunywe kahle, ngaphandle kwalokho izobangela umonakalo waphakade kudivayisi.
- Kunezingxenye ezikhiqiza amandla kagesi aphezulu kanye nokushisa ebhodini lesifunda ngemva kokuba imodyuli yokuhlela ivuliwe. Ungathinti ibhodi lesifunda ngezandla zakho lapho imodyuli yokuhlela isebenza.
