Ukufika okusha – 1535nm Erbium laser rangefinder module

01 Isingeniso

Eminyakeni yakamuva, ngokuvela kwezinkundla zokulwa ezingenamuntu, ama-drones nemishini ephathekayo yamasosha ngamanye, izitholi ze-laser eziphathwa ngesandla zebanga elide zibonise amathuba abanzi okusebenza. Ubuchwepheshe be-laser yengilazi ye-Erbium enobude obungu-1535nm buya ngokuya buvuthwa. Inezinzuzo zokuphepha kwamehlo, ikhono eliqinile lokungena entuthuni, kanye nebanga elide, futhi iyisiqondiso esibalulekile sokuthuthukiswa kobuchwepheshe be-laser.

02 Isingeniso Somkhiqizo

I-LSP-LRS-0310 F-04 laser rangefinder iyi-laser rangefinder eyakhiwe ngokusekelwe ku-1535nm Er glass laser eyakhiwe ngokuzimele yiLumispot. Isebenzisa indlela entsha ye-single-pulse time-of-flight (TOF) esukela , futhi ukusebenza kwayo okuhlukahlukene kuhle kakhulu ezinhlotsheni ezihlukene zokuhlosiwe - ibanga elisukela kumabhilidi lingafika kalula kumakhilomitha angu-5, futhi ngisho nasezimotweni ezigijimayo, iyalithola. ingakwazi ukufinyelela esitebeleni esisukela kumakhilomitha angu-3.5. Ezimeni zohlelo lokusebenza ezifana nokuqapha abasebenzi, ibanga elisukela kubantu lingaphezu kwamakhilomitha angu-2, okuqinisekisa ukunemba kanye nemvelo yesikhathi sangempela sedatha. I-laser rangefinder ye-LSP-LRS-0310F-04 isekela ukuxhumana nekhompuyutha engumsingathi ngembobo yochungechunge ye-RS422 (isevisi yokwenza ngokwezifiso i-TTL serial port nayo ihlinzekwa), okwenza ukudluliswa kwedatha kube lula futhi kusebenze kahle.

03 Izici Zomkhiqizo

* Idizayini edidiyelwe yokwandiswa kwe-Beam: ukuhlanganiswa okuphumelelayo kanye nokuvumelana nezimo kwemvelo okuthuthukisiwe

Idizayini edidiyelwe yokunwetshwa kwemishayo iqinisekisa ukuxhumana okunembile nokusebenzisana okuphumelelayo phakathi kwezingxenye. Umthombo wepompo we-LD unikeza okokufaka kwamandla okuzinzile nokusebenza kahle kwe-laser medium, i-axis collimator esheshayo nesibuko esigxilile silawula ngokunembile ukwakheka kwe-beam, imojula yokuzuza ikhulisa amandla e-laser, futhi isinwebesi se-beam sandisa ngempumelelo ububanzi be-beam, sinciphisa ugongolo. i-divergence angle, futhi ithuthukisa ukuqondisa kwe-beam nebanga lokudlulisela. I-optical sampling module iqapha ukusebenza kwe-laser ngesikhathi sangempela ukuze kuqinisekiswe ukuphuma okuzinzile nokuthembekile. Ngesikhathi esifanayo, umklamo ovaliwe unobungani bemvelo, unweba impilo yesevisi ye-laser, futhi unciphisa izindleko zokuyilungisa.

* Imodi yokulinganisa ibanga lokushintsha ingxenye: ukulinganisa okunembile ukuze kuthuthukiswe ukunemba kokulinganisa ibanga

Indlela yokushintsha ehlukanisiwe ithatha isilinganiso esinembile njengomongo wayo. Ngokuthuthukisa umklamo wendlela yokubona kanye nama-algorithms okucubungula isignali athuthukisiwe, kuhlanganiswe nokuphuma kwamandla aphezulu kanye nezici ze-pulse amade we-laser, ingangena ngempumelelo ukuphazamiseka komkhathi futhi iqinisekise ukuzinza nokunemba kwemiphumela yokulinganisa. Lobu buchwepheshe busebenzisa isu lokuphindaphinda imvamisa ephezulu yokukhipha ama-laser pulses ngokuqhubekayo futhi buthelele futhi bucubungule amasignali e-echo, ukucindezela ngempumelelo umsindo nokuphazamiseka, ukuthuthukisa kakhulu isilinganiso sesignali-kumsindo, kanye nokuzuza ukukalwa okunembile kwebanga eliqondiwe. Ngisho nasezindaweni eziyinkimbinkimbi noma lapho kubhekene nezinguquko ezincane, izindlela zokushintsha ezihlukanisiwe zisengaqinisekisa ukunemba nokuzinza kwemiphumela yokulinganisa, kube izindlela zobuchwepheshe ezibalulekile zokuthuthukisa ukunemba okuhlukahlukene.

*I-Double threshold scheme inxephezela ukunemba okusukela kabili: ukulinganisa okuphindwe kabili, ukudlula ukunemba komkhawulo

Umnyombo we-double-threshold scheme usendleleni yawo yokulinganisa okukabili. Isistimu iqala ngokusetha imikhawulo yesignali emibili ehlukene ukuze ithwebule amaphuzu amabili esikhathi esibalulekile esignali ye-echo eqondiwe. Lawa maphoyinti esikhathi amabili ahluke kancane ngenxa yemikhawulo ehlukene, kodwa yilo mehluko oba ukhiye wokunxephezela amaphutha. Ngokulinganisa isikhathi nokunemba okuphezulu nokubala, isistimu ingakwazi ukubala ngokunembile umehluko wesikhathi phakathi kwalawa maphuzu amabili ngesikhathi, futhi ilinganise kahle imiphumela yasekuqaleni esukelayo ngokufanele, ngaleyo ndlela ithuthukise ngokuphawulekayo ukunemba okuhlukahlukene.

Umfanekiso 3 Umdwebo wohlelo lwesinxephezelo se-double threshold algorithm esukela ngokunemba

* Idizayini yokusetshenziswa kwamandla okuphansi: ukusebenza kahle okuphezulu, ukonga amandla, ukusebenza okulungiselelwe

Ngokusetshenziswa okujulile kwamamojula wesekethe njengebhodi lokulawula eliyinhloko kanye nebhodi lomshayeli, samukele ama-chips anamandla aphansi athuthukile kanye namasu okuphatha amandla asebenzayo ukuze siqinisekise ukuthi kumodi yokulinda, ukusetshenziswa kwamandla esistimu kulawulwa ngokuqinile ngaphansi kuka-0.24W, okuyinto kuwukuncishiswa okuphawulekayo uma kuqhathaniswa nemiklamo yendabuko. Kumafrikhwensi ahlukahlukene we-1Hz, ukusetshenziswa kwamandla sekukonke nakho kugcinwa ngaphakathi kwe-0.76W, okubonisa ukusebenza kahle kwamandla okuhle kakhulu. Esimeni sokusebenza esiphezulu, nakuba ukusetshenziswa kwamandla kuzokwanda, kusalawulwa ngokuphumelelayo ngaphakathi kwe-3W, iqinisekisa ukusebenza okuzinzile kwemishini ngaphansi kwezidingo eziphezulu zokusebenza ngenkathi kucatshangelwa imigomo yokonga amandla.

* Amandla okusebenza ngokwedlulele: ukuchithwa kokushisa okuhle kakhulu, ukuqinisekisa ukusebenza okuzinzile nokusebenza kahle

Ukuze ubhekane nenselele yokushisa ephezulu, i-laser ye-LSP-LRS-0310F-04 rangefinder isebenzisa isistimu ethuthukisiwe yokukhipha ukushisa. Ngokulungiselela indlela yokushisa yangaphakathi, ukwandisa indawo yokushisa ukushisa nokusebenzisa izinto zokushisa ezisezingeni eliphezulu, umkhiqizo ungasusa ngokushesha ukushisa kwangaphakathi okukhiqizwa, uqinisekisa ukuthi izingxenye eziyinhloko zingakwazi ukugcina izinga lokushisa elifanele lokusebenza ngaphansi komthwalo ophezulu wesikhathi eside. ukusebenza. Leli khono elihle kakhulu lokukhipha ukushisa aligcini nje ngokunweba impilo yesevisi yomkhiqizo, kodwa futhi liqinisekisa ukuzinza nokuvumelana kokusebenza okuhlukahlukene.

* Ukuphatheka nokuqina: idizayini encane, ukusebenza okuhle kakhulu okuqinisekisiwe

I-LSP-LRS-0310F-04 laser rangefinder ibonakala ngobukhulu bayo obuncane obumangalisayo (amagremu angu-33 kuphela) nesisindo esilula, kuyilapho kucatshangelwa izinga eliphezulu kakhulu lokusebenza okuzinzile, ukumelana nomthelela ophezulu kanye nokuphepha kwamehlo kwezinga lokuqala, okubonisa okuphelele. ibhalansi phakathi kokuphatheka nokuqina. Idizayini yalo mkhiqizo ikhombisa ngokugcwele ukuqonda okujulile kwezidingo zabasebenzisi kanye nezinga eliphezulu lokuhlanganiswa kokuqanjwa kabusha kwezobuchwepheshe, kube yinto okugxilwe kuyo ukunakwa emakethe.

04 Isicelo Scenario

Isetshenziswa emikhakheni eminingi ekhethekile njengokuphokophela nokusukela, ukubeka izithombe zikagesi, ama-drones, izimoto ezingenamuntu, amarobhothi, izinhlelo zokuthutha ezihlakaniphile, ukukhiqiza okukhaliphile, ukugcinwa kwezinto ezihlakaniphile, ukukhiqizwa okuphephile, nokuphepha okukhaliphile.

06 Iziqondiso

* I-laser ekhishwe yile moduli ehlukahlukene ingu-1535nm, ephephile emehlweni abantu. Nakuba kuwubude obuphephile bamehlo omuntu, kunconywa ukuthi ungabheki ngqo i-laser;

* Lapho ulungisa ukufana kwezimbazo ezintathu ze-optical, qiniseka ukuthi uvimba ilensi etholayo, ngaphandle kwalokho umtshina uzolimala unomphela ngenxa yokunanela ngokweqile;

* Le mojula ehlukahlukene ayinawo umoya. Qinisekisa ukuthi umswakama ohlobene wendawo ungaphansi kuka-80% futhi ugcine indawo ezungezile ihlanzekile ukugwema ukulimaza i-laser.

* Ububanzi bemojuli ehlukanisiwe buhlobene nokubonakala komkhathi kanye nemvelo yethagethi. Ububanzi buzoncishiswa ezimweni zenkungu, imvula neziphepho zesihlabathi. Okuqondisiwe okunjengamaqabunga aluhlaza, izindonga ezimhlophe, ne-limestone eveziwe kunokubonakala okuhle futhi kungandisa ububanzi. Ukwengeza, lapho i-engeli yokuthambekela kokuqondisiwe ku-laser beam ikhuphuka, ububanzi buzoncishiswa;

* Akuvunyelwe ngokuphelele ukudubula i-laser ezindaweni ezihlosiwe eziqinile njengengilazi nezindonga ezimhlophe phakathi kwamamitha angu-5, ukuze ugweme i-echo ukuthi iqine kakhulu futhi ibangele umonakalo kumtshina we-APD;

* Akuvunyelwe ngokuphelele ukuxhuma noma ukukhipha ikhebula lapho amandla evuliwe;

* Qinisekisa ukuthi i-polarity yamandla ixhunywe ngendlela efanele, ngaphandle kwalokho izodala umonakalo unomphela kudivayisi.
