Ukufika okusha – imodyuli ye-Erbium laser rangefinder engu-1535nm

01 Isingeniso

Eminyakeni yamuva nje, ngokuvela kwamapulatifomu okulwa angenamuntu, ama-drone kanye nemishini ephathekayo yamasosha ngamanye, ama-rangefinder e-laser asebenza isikhathi eside afakwe ngesandla abonise amathuba amaningi okusetshenziswa. Ubuchwepheshe be-laser yengilazi ye-Erbium obunobude obungu-1535nm buya ngokuya bukhula. Bunezinzuzo zokuphepha kwamehlo, ikhono elinamandla lokungena entuthwini, kanye nebanga elide, futhi buyisiqondiso esiyinhloko sokuthuthukiswa kobuchwepheshe be-laser.

02 Isingeniso Somkhiqizo

I-LSP-LRS-0310 F-04 laser rangefinder iyi-laser rangefinder ethuthukiswe ngokusekelwe ku-1535nm Er glass laser eyenziwe ngokuzimela yi-Lumispot. Isebenzisa indlela entsha yokulinganisa isikhathi sokundiza esisodwa (TOF), futhi ukusebenza kwayo kokulinganisa kuhle kakhulu ezinhlotsheni ezahlukene zezinhloso - ibanga lokulinganisa lezakhiwo lingafinyelela kalula amakhilomitha ama-5, futhi ngisho nasezimotweni ezihamba ngokushesha, ingafinyelela ibanga elizinzile lamakhilomitha ama-3.5. Ezimweni zokusetshenziswa ezifana nokuqapha abasebenzi, ibanga lokulinganisa labantu lingaphezu kwamakhilomitha ama-2, okuqinisekisa ukunemba kanye nohlobo lwedatha ngesikhathi sangempela. I-LSP-LRS-0310F-04 laser rangefinder isekela ukuxhumana nekhompyutha ephethe nge-RS422 serial port (insizakalo yokwenza ngokwezifiso i-TTL serial port nayo inikezwa), okwenza ukudluliswa kwedatha kube lula futhi kusebenze kahle.

03 Izici Zomkhiqizo

* Umklamo ohlanganisiwe wokwandiswa kwe-beam: ukuhlanganiswa okusebenzayo kanye nokuthuthukiswa kokuzivumelanisa nezimo kwemvelo

Umklamo wokwandiswa kwe-beam ohlanganisiwe uqinisekisa ukuhlanganiswa okunembile kanye nokubambisana okuphumelelayo phakathi kwezingxenye. Umthombo wephampu ye-LD unikeza ukufakwa kwamandla okuzinzile nokusebenzayo kwe-laser medium, i-fast axis collimator kanye nesibuko esigxilisayo kulawula ngokunembile ukuma kwe-beam, i-gain module ikhulisa amandla e-laser, kanti i-beam expander yandisa ngempumelelo ububanzi be-beam, inciphisa i-engeli yokuhlukana kwe-beam, futhi ithuthukise ukuqondisa kwe-beam kanye nebanga lokudlulisela. I-optical sampling module iqapha ukusebenza kwe-laser ngesikhathi sangempela ukuqinisekisa umphumela ozinzile nothembekile. Ngesikhathi esifanayo, umklamo ovaliwe unobungani nemvelo, wandisa impilo yesevisi ye-laser, futhi unciphisa izindleko zokulungisa.

* Imodi yokulinganisa ibanga lokushintsha ingxenye: ukulinganisa okunembile ukuthuthukisa ukunemba kokulinganisa ibanga

Indlela yokushintshanisa ngezigaba ithatha isilinganiso esinembile njengengqikithi yayo. Ngokwenza ngcono ukwakheka kwendlela yokukhanya kanye nama-algorithms okucubungula amasignali athuthukile, kuhlanganiswe nokukhishwa kwamandla aphezulu kanye nezici zokushaya kwenhliziyo okude kwe-laser, ingangena ngempumelelo ekuphazamisekeni komoya futhi iqinisekise ukuzinza nokunemba kwemiphumela yokulinganisa. Lobu buchwepheshe busebenzisa isu lokuphindaphinda kwemvamisa ephezulu ukuze kukhishwe njalo ama-laser pulse amaningi futhi kuqoqwe futhi kucutshungulwe amasignali e-echo, kucindezelwe ngempumelelo umsindo nokuphazamiseka, kuthuthukiswe kakhulu isilinganiso sesignali kuya komsindo, futhi kufezwe ukulinganisa okunembile kwebanga eliqondiwe. Ngisho nasezindaweni eziyinkimbinkimbi noma lapho kubhekene nezinguquko ezincane, izindlela zokushintshanisa ngezigaba zisengaqinisekisa ukunemba nokuqina kwemiphumela yokulinganisa, zibe yindlela ebalulekile yobuchwepheshe yokuthuthukisa ukunemba kwezigaba.

*Uhlelo lwe-double threshold luhlanganisa ukunemba okuhlukahlukene: ukulinganisa okuphindwe kabili, ngaphezu kokunemba okulinganiselwe

Ingqikithi yesikimu se-dual-threshold isekusebenzeni kwayo kokulinganisa okubili. Uhlelo luqala ngokusetha imingcele emibili ehlukene yesignali ukuze lubambe amaphuzu amabili esikhathi abalulekile esignali ye-echo eqondiwe. Lawa maphuzu amabili esikhathi ahlukile kancane ngenxa yemingcele ehlukene, kodwa yilo mehluko oba yisihluthulelo sokubuyisela amaphutha. Ngokulinganisa isikhathi okunembe kakhulu nokubala, uhlelo lungabala ngokunembile umehluko wesikhathi phakathi kwala maphuzu amabili ngesikhathi, futhi lulinganise kahle imiphumela yokuqala yokulinganisa ngokufanele, ngaleyo ndlela luthuthukise kakhulu ukunemba kokulinganisa.

* Umklamo wokusetshenziswa kwamandla aphansi: ukusebenza kahle okuphezulu, ukonga amandla, ukusebenza kahle

Ngokusebenzisa kahle amamojula wesekethe njengebhodi lokulawula eliyinhloko kanye nebhodi lomshayeli, sisebenzise ama-chip asezingeni eliphezulu anamandla aphansi kanye namasu okuphatha amandla asebenzayo ukuqinisekisa ukuthi kwimodi yokulinda, ukusetshenziswa kwamandla esistimu kulawulwa ngokuqinile ngaphansi kuka-0.24W, okuwukwehla okukhulu uma kuqhathaniswa nemiklamo yendabuko. Ngemvamisa ehlukahlukene engu-1Hz, ukusetshenziswa kwamandla okuphelele nakho kugcinwa ngaphakathi kuka-0.76W, okubonisa ukusebenza kahle kwamandla okuhle kakhulu. Esimweni sokusebenza esiphezulu, yize ukusetshenziswa kwamandla kuzokwanda, kusalawulwa ngempumelelo ngaphakathi kuka-3W, kuqinisekisa ukusebenza okuzinzile kwemishini ngaphansi kwezidingo zokusebenza okuphezulu ngenkathi kucatshangelwa imigomo yokonga amandla.

* Amandla okusebenza ngokweqile: ukushabalalisa ukushisa okuhle kakhulu, ukuqinisekisa ukusebenza okuzinzile nokusebenza kahle

Ukuze kuhlangatshezwane nenselele yokushisa okuphezulu, i-LSP-LRS-0310F-04 laser rangefinder isebenzisa uhlelo oluthuthukisiwe lokusabalalisa ukushisa. Ngokwenza ngcono indlela yokuqhuba ukushisa kwangaphakathi, ukwandisa indawo yokusabalalisa ukushisa nokusebenzisa izinto zokusabalalisa ukushisa ezisebenza kahle kakhulu, umkhiqizo ungasusa ngokushesha ukushisa kwangaphakathi okukhiqizwayo, uqinisekise ukuthi izingxenye eziyinhloko zingagcina izinga lokushisa elifanele lokusebenza ngaphansi kokusebenza komthwalo wesikhathi eside. Leli khono elihle kakhulu lokusabalalisa ukushisa aligcini nje ngokwandisa impilo yesevisi yomkhiqizo, kodwa futhi liqinisekisa ukuzinza kanye nokuvumelana kokusebenza okuhlukahlukene.

* Ukuphatheka nokuqina: ukwakheka okuncane, ukusebenza okuhle kakhulu kuqinisekisiwe

I-laser rangefinder ye-LSP-LRS-0310F-04 iphawuleka ngobukhulu bayo obuncane obumangalisayo (amagremu angu-33 kuphela) kanye nesisindo esincane, kuyilapho kucatshangelwa ikhwalithi enhle yokusebenza okuzinzile, ukumelana nomthelela omkhulu kanye nokuphepha kwamehlo kwezinga lokuqala, okubonisa ibhalansi ephelele phakathi kokuthwala nokuqina. Umklamo walo mkhiqizo ubonisa ngokugcwele ukuqonda okujulile kwezidingo zomsebenzisi kanye nezinga eliphezulu lokuhlanganiswa kokusungula izinto ezintsha kwezobuchwepheshe, okuba yinto ebalulekile emakethe.

04 Isimo Sesicelo

Isetshenziswa emikhakheni eminingi ekhethekile efana nokukhomba nokuqondisa, ukubeka i-photoelectric, ama-drone, izimoto ezingenamuntu, amarobhothi, izinhlelo zokuhamba ezihlakaniphile, ukukhiqiza okuhlakaniphile, ukuthutha okuhlakaniphile, ukukhiqiza okuphephile, kanye nokuphepha okuhlakaniphile.

06 Iziqondiso

* I-laser ekhishwa yile module ejikelezayo ingu-1535nm, okuphephile emehlweni abantu. Nakuba iyi-wavelength ephephile emehlweni abantu, kutuswa ukuthi ungayibheki ngqo i-laser;

* Uma ulungisa ukufana kwezimbazo ezintathu ze-optical, qiniseka ukuthi uvimba ilensi eyamukelayo, ngaphandle kwalokho i-detector izolimala unomphela ngenxa ye-echo eyeqile;

* Le module yokulinganisa ayingeni moya. Qiniseka ukuthi umswakama wendawo ungaphansi kuka-80% futhi ugcine indawo ihlanzekile ukuze ugweme ukulimaza i-laser.

* Ububanzi bemojuli yokuzungeza buhlobene nokubonakala komoya kanye nohlobo lwento eqondiwe. Ububanzi buzoncishiswa ezimweni zenkungu, imvula kanye neziphepho zesihlabathi. Izinto eziqondiwe ezifana namaqabunga aluhlaza, izindonga ezimhlophe, kanye ne-limestone eveziwe zinokukhanya okuhle futhi kungandisa ububanzi. Ngaphezu kwalokho, lapho i-engeli yokuthambekela kwento eqondiwe emsebeni we-laser ikhula, ububanzi buzoncishiswa;

* Akuvunyelwe ngokuphelele ukudubula nge-laser ezindaweni ezikhanyayo eziqinile njengengilazi nezindonga ezimhlophe ngaphakathi kwamamitha ama-5, ukuze kugwenywe ukuthi umsindo uqine kakhulu futhi ubangele umonakalo kumtholi we-APD;

* Akuvunyelwe ngokuphelele ukuxhuma noma ukukhipha ikhebula uma ugesi uvuliwe;

* Qiniseka ukuthi i-polarity yamandla ixhunywe kahle, ngaphandle kwalokho izobangela umonakalo ongapheli kudivayisi.
