Kusvika kutsva - 1535nm Erbium laser rangefinder module

01 Nhanganyaya

Mumakore achangopfuura, nekubuda kwemapuratifomu ehondo asina vanhu, madrone nemidziyo inotakurika yemasoja ega ega, michina midiki yelaser rangefinders yakatorwa nemaoko yakaratidza mikana yakawanda yekushandisa. Tekinoroji yelaser range yegirazi yeErbium ine wavelength ye1535nm iri kuramba ichikura. Ine mabhenefiti ekuchengetedza maziso, kugona kwakasimba kupinda muutsi, uye kure kure, uye ndiyo nzira huru yekuvandudza tekinoroji yelaser rangeing.

02 Nhanganyaya yeChigadzirwa

Iyo LSP-LRS-0310 F-04 laser rangefinder irangefinder yelaser yakagadzirwa zvichibva pa 1535nm Er glass laser yakagadzirwa yakazvimirira neLumispot. Inoshandisa nzira itsva ye single-pulse time-of-flight (TOF) ranging method, uye mashandiro ayo erangi akanakira marudzi akasiyana ezvinangwa - daro rerangi rezvivakwa rinogona kusvika makiromita mashanu zviri nyore, uye kunyangwe kumotokari dzinofamba nekukurumidza, inogona kuwana rangi yakagadzikana yemakiromita 3.5. Muzviitiko zvekushandisa zvakaita sekutarisa vashandi, daro rerangi revanhu rinodarika makiromita maviri, zvichivimbisa kururama uye hunhu hwedata panguva chaiyo. Iyo LSP-LRS-0310F-04 laser rangefinder inotsigira kutaurirana nekombuta yemushandi kuburikidza neRS422 serial port (TTL serial port customization service inopihwawo), zvichiita kuti kutumira data kuve nyore uye kunoshanda.

03 Zvimiro zveChigadzirwa

* Dhizaini yakabatanidzwa yekuwedzera danda: kubatanidzwa kwakanaka uye kugadziriswa kwezvakatipoteredza kwakawedzerwa

Dhizaini yekuwedzera beam yakabatanidzwa inoita kuti pave nekubatana kwakaringana uye kushanda pamwe chete zvakanaka pakati pezvikamu. Sosi yepombi yeLD inopa simba rakasimba uye rinoshanda rekushandisa laser medium, fast axis collimator negirazi rinotarisisa zvinodzora chimiro chebeam nemazvo, gain module inowedzera simba relaser, uye beam expander inonyatso kuwedzera dhayamita yebeam, inoderedza angle yekusiyana kwebeam, uye inovandudza kutungamira kwebeam uye daro rekutumira. Optical sampling module inotarisa mashandiro elaser munguva chaiyo kuti ive nechokwadi chekuti kubuda kwayo kwakasimba uye kwakavimbika. Panguva imwe chete, dhizaini yakavharwa haina njodzi kune zvakatipoteredza, inowedzera hupenyu hwebasa relaser, uye inoderedza mari yekugadzirisa.

Mufananidzo 2 Mufananidzo chaiwo we erbium glass laser

* Chikamu chinoshandura daro rekuyera nzira: chiyero chaicho chekuvandudza kurongeka kwekuyera daro

Nzira yekushandura yakapatsanurwa inotora chiyero chakarurama sechinokosha chayo. Nekugadzirisa dhizaini yenzira yekuona uye maalgorithms epamusoro ekugadzirisa masaini, pamwe chete nemagetsi akawandisa uye hunhu hwemapundu marefu elaser, inogona kubudirira kupinda mumhepo inopindira uye kuve nechokwadi chekugadzikana uye kururama kwemhedzisiro yekuyera. Iyi tekinoroji inoshandisa nzira yepamusoro yekudzora frequency kuti irambe ichiburitsa mapulse akawanda elaser uye kuunganidza nekugadzirisa masaini eecho, zvinobudirira kudzvinyirira ruzha nekupindira, kuvandudza zvakanyanya chiyero chesignal-to-noise, uye kuwana chiyero chakarurama chedaro rakatarwa. Kunyangwe munzvimbo dzakaoma kana paine shanduko diki, nzira dzekushandura dzakapatsanurwa dzinogona kuramba dzichiona kururama nekugadzikana kwemhedzisiro yekuyera, zvichiva nzira yakakosha yehunyanzvi yekuvandudza kururama kwekuyera.

*Chirongwa che double threshold chinobhadhara kururama kwemarudzi akasiyana: calibration kaviri, kupfuura kururama kwemuganhu

Chinhu chikuru chechirongwa chedual-threshold chiri muchimiro chayo che dual calibration. Sisitimu iyi inotanga yaisa ma signal threshold maviri akasiyana kuti itore ma critical time points maviri e target echo signal. Aya ma time points maviri akasiyana zvishoma nekuda kwe ma thresholds akasiyana, asi mutsauko uyu ndiwo unova kiyi yekutsiva zvikanganiso. Kuburikidza nekuyera nguva nemazvo uye kuverenga, sisitimu inogona kuverenga nemazvo musiyano wenguva pakati pema points maviri aya munguva, uye kugadzirisa mhedzisiro yekutanga yeku ranging zvinoenderana, nokudaro ichivandudza zvikuru kururama kweku ranging.

Mufananidzo 3. Dhiyagiramu yechirongwa chekuenzanisa nzira mbiri dzekugadzirisa miganhu ye algorithm

* Dhizaini yekushandisa simba shoma: kushanda zvakanaka, kuchengetedza simba, kushanda zvakanaka

Kuburikidza nekugadzirisa zvakadzama mamodule ecircuit akadai semain control board nedriver board, takashandisa machipisi emagetsi mashoma uye nzira dzekugadzirisa simba dzinoshanda zvakanaka kuti tive nechokwadi chekuti mu standby mode, kushandiswa kwesimba resystem kunodzorwa zvakanyanya pasi pe 0.24W, izvo zvinoderedza zvakanyanya kana tichienzanisa nemagadzirirwo echinyakare. Pa frequency ye 1Hz, kushandiswa kwesimba rese kunochengetwawo mukati me 0.76W, zvichiratidza kushanda zvakanaka kwesimba. Mumamiriro ekushanda akanyanya, kunyangwe kushandiswa kwesimba kuchizowedzera, kuchiri kudzorwa zvinobudirira mukati me 3W, zvichivimbisa kushanda kwakasimba kwemidziyo pasi pezvinodiwa zvepamusoro tichifunga nezvezvinangwa zvekuchengetedza simba.

* Kugona kushanda kwakanyanya: kupisa kwakanaka kwazvo, kuve nechokwadi chekuti kushanda kwakasimba uye kwakanaka

Kuti ikwanise kugadzirisa dambudziko rekupisa kwakanyanya, LSP-LRS-0310F-04 laser rangefinder inoshandisa sisitimu yepamusoro yekupisa. Nekugadzirisa nzira yekupisa yemukati, kuwedzera nzvimbo yekupisa uye kushandisa zvinhu zvinopisa zvakanyanya, chigadzirwa chinogona kukurumidza kubvisa kupisa kwemukati, zvichiita kuti zvikamu zvepakati zvigone kuchengetedza tembiricha yakakodzera yekushanda pasi pekushanda kwenguva refu. Kugona uku kwakanaka kwekupisa hakungowedzere hupenyu hwebasa rechigadzirwa chete, asiwo kunovimbisa kugadzikana uye kugara kwenguva refu kwekushanda kwakasiyana-siyana.

* Kutakurwa uye kugara kwenguva refu: dhizaini diki, mashandiro akanaka kwazvo akavimbiswa

Iyo LSP-LRS-0310F-04 laser rangefinder inozivikanwa nehukuru hwayo hudiki hunoshamisa (magiramu 33 chete) uye huremu hwakareruka, uku tichifunga nezvemhando yepamusoro yekushanda kwakasimba, kuramba kusimba kwakanyanya uye kuchengetedzeka kwemaziso epamusoro, zvichiratidza kuenzana kwakakwana pakati pekugona kutakurwa uye kugara kwenguva refu. Dhizaini yechigadzirwa ichi inoratidza zvizere kunzwisisa kwakadzama kwezvinodiwa nemushandisi uye mwero wepamusoro wekubatanidzwa kwehunyanzvi hwetekinoroji, zvichiva chinhu chinonyanya kutariswa mumusika.

04 Mamiriro Ekushandisa

Inoshandiswa muminda yakawanda yakakosha yakadai sekunanga nekuronga, kuisa ma photoelectric positioning, ma drones, mota dzisina vanhu, marobhoti, masisitimu ekufambisa akangwara, kugadzira akangwara, logistics akangwara, kugadzira kwakachengeteka, uye kuchengetedzwa kwakangwara.

06 Nhungamiro

* Laser inoburitswa neiyi ranging module i1535nm, iyo yakachengeteka kumaziso evanhu. Kunyangwe iri wavelength yakachengeteka kumaziso evanhu, zvinokurudzirwa kuti usatarise zvakananga pa laser;

* Paunenge uchigadzirisa parallelism yema optical axes matatu, iva nechokwadi chekuvhara lenzi inogamuchira, zvikasadaro detector ichakuvara zvachose nekuda kwe echo yakawandisa;

* Iyi module yekuyera haina mhepo. Ita shuwa kuti hunyoro hwenzvimbo huri pasi pe80% uye chengetedza nzvimbo yakachena kudzivirira kukuvadza laser.

* Kureba kwechikamu che "ranging module" kwakabatana nekuonekwa kwemhepo uye hunhu hwechinangwa. Kureba kwechikamu kuchaderedzwa kana paine mhute, mvura uye mamiriro ejecha. Zvinangwa zvakaita semashizha egirini, madziro machena, uye limestone yakafumurwa zvine reflectivity yakanaka uye zvinogona kuwedzera kureba kwechikamu. Pamusoro pezvo, kana kona yekutsvedza kwechinangwa ichi kuchiedza chelaser ikawedzera, kureba kwechikamu kuchaderedzwa;

* Zvinorambidzwa zvachose kupfura nelaser pazvinangwa zvakasimba zvinopenya zvakaita segirazi nemadziro machena mukati memamita mashanu, kuitira kudzivirira kuti echo isanyanya kusimba uye kukonzera kukuvara kweAPD detector;

* Zvinorambidzwa chose kubatanidza kana kubvisa tambo kana magetsi achishanda;

* Iva nechokwadi chekuti polarity yemagetsi yakabatana nemazvo, zvikasadaro ichakonzera kukuvara kwechigarire kumudziyo.
