Kufika kwatsopano - 1535nm Erbium laser rangefinder module

01 Chiyambi

M'zaka zaposachedwa, pakutuluka kwa nsanja zopanda anthu, ma drones ndi zida zonyamula za asitikali aliyense payekha, zowunikira zam'manja zamtundu wautali za laser zawonetsa chiyembekezo chachikulu chogwiritsa ntchito. Erbium galasi laser kuyambira luso ndi wavelength 1535nm akukhala okhwima kwambiri. Lili ndi ubwino wa chitetezo cha maso, mphamvu yamphamvu yolowera utsi, ndi utali wautali, ndipo ndi njira yofunika kwambiri pa chitukuko cha luso la laser.

02 Chiyambi cha Zamalonda

LSP-LRS-0310 F-04 laser rangefinder ndi laser rangefinder yopangidwa kutengera 1535nm Er glass laser yopangidwa modziyimira payokha ndi Lumispot. Imatengera njira yoyambira ya single-pulse time-of-flight (TOF) , ndipo magwiridwe ake ndi abwino kwambiri pamitundu yosiyanasiyana ya mipherezero - mtunda woyambira wanyumba ukhoza kufika mtunda wa makilomita 5, komanso ngakhale magalimoto othamanga akhoza kufika mtunda wokhazikika wa makilomita 3.5. Muzochitika zogwiritsira ntchito monga kuwunika kwa ogwira ntchito, mtunda wa anthu ndi wopitilira makilomita awiri, kuwonetsetsa kulondola komanso nthawi yeniyeni ya deta. LSP-LRS-0310F-04 laser rangefinder imathandizira kulumikizana ndi makompyuta omwe abwera nawo kudzera pa doko la RS422 serial port (TTL serial port customization service imaperekedwanso), kupangitsa kufalitsa kwa data kukhala kosavuta komanso kothandiza.

* Mapangidwe ophatikizika a Beam: kuphatikiza koyenera komanso kusinthika kwachilengedwe

Mapangidwe ophatikizika owonjezera amatsimikizira kulumikizana kolondola komanso mgwirizano wabwino pakati pa zigawozo. Gwero la mpope la LD limapereka mphamvu zokhazikika komanso zogwira mtima za sing'anga ya laser, cholumikizira cholumikizira mwachangu ndi galasi loyang'ana bwino kuwongolera mawonekedwe a mtengo, gawo lopindula limakulitsa mphamvu ya laser, ndipo chowonjezera chamtengo chimakulitsa kukula kwa mtengowo, kumachepetsa mtengowo. divergence ngodya, ndi bwino Directivity mtengo ndi kufala mtunda. Optical sampling module imayang'anira magwiridwe antchito a laser munthawi yeniyeni kuti atsimikizire kutulutsa kokhazikika komanso kodalirika. Panthawi imodzimodziyo, mapangidwe osindikizidwa ndi ochezeka ndi chilengedwe, amakulitsa moyo wautumiki wa laser, ndipo amachepetsa mtengo wokonza.

* Njira yoyezera mtunda wosinthira magawo: muyeso wolondola kuti muwongolere kulondola kwa mtunda

Njira yosinthira magawo amatengera muyeso wolondola ngati maziko ake. Mwa kukhathamiritsa kapangidwe ka njira ya kuwala ndi ma aligorivimu apamwamba opangira ma siginecha, kuphatikiza kutulutsa kwamphamvu kwamphamvu komanso mawonekedwe amtundu wautali wa laser, imatha kulowa bwino kusokoneza kwamlengalenga ndikuwonetsetsa kukhazikika komanso kulondola kwazotsatira zake. Tekinolojeyi imagwiritsa ntchito njira yobwerezabwereza pafupipafupi kuti itulutse ma pulse angapo a laser ndikuwunjikana ndikusintha ma echo ma sign, kupondereza bwino phokoso ndi kusokoneza, kuwongolera kwambiri chiŵerengero cha ma sign-to-phokoso, ndikukwaniritsa muyeso wolondola wa mtunda womwe mukufuna. Ngakhale m'malo ovuta kapena poyang'anizana ndi kusintha kwakung'ono, njira zosinthira magawo zimatha kutsimikizira kulondola komanso kukhazikika kwa zotsatira zoyezera, kukhala njira yofunikira yaukadaulo yosinthira kulondola koyambira.

*Double threshold scheme limalipira kulondola koyambira: kuwerengetsa kawiri, kupitirira malire olondola

Pakatikati pa dongosolo la dual-threshold scheme lagona pamakina ake apawiri. Dongosolo limayamba kuyika magawo awiri osiyana azizindikiro kuti agwire mfundo ziwiri zofunika kwambiri za chizindikiro cha echo chandamale. Nthawi ziwirizi ndizosiyana pang'ono chifukwa cha malire osiyanasiyana, koma kusiyana kumeneku kumakhala chinsinsi chobwezera zolakwika. Kupyolera muyeso wanthawi yolondola kwambiri komanso kuwerengera, dongosololi limatha kuwerengera molondola kusiyana kwa nthawi pakati pa mfundo ziwirizi munthawi yake, ndikuwongolera bwino zotsatira zoyambira molingana, motero kuwongolera kulondola kosiyanasiyana.

* Mapangidwe ogwiritsira ntchito mphamvu zochepa: kuchita bwino kwambiri, kupulumutsa mphamvu, kuchita bwino

Kupyolera mu kukhathamiritsa mozama ma modules ozungulira monga bolodi lalikulu loyendetsa ndi bolodi la dalaivala, tatengera tchipisi tating'onoting'ono tamphamvu komanso njira zoyendetsera mphamvu zowonetsetsa kuti mumayendedwe oyimilira, kugwiritsa ntchito mphamvu zamagetsi kumayendetsedwa mosamalitsa pansipa 0.24W, yomwe ndi kuchepa kwakukulu poyerekeza ndi mapangidwe achikhalidwe. Pamaulendo osiyanasiyana a 1Hz, kugwiritsa ntchito mphamvu zonse kumasungidwanso mkati mwa 0.76W, kuwonetsa mphamvu zamagetsi. Pachimake chogwira ntchito, ngakhale kuti mphamvu yogwiritsira ntchito mphamvu idzawonjezeka, imayang'aniridwa bwino mkati mwa 3W, kuonetsetsa kuti zipangizozi zikugwira ntchito pansi pa zofunikira kwambiri poganizira zolinga zopulumutsa mphamvu.

* Kuthekera kogwira ntchito kwambiri: kutentha kwabwino kwambiri, kuwonetsetsa kugwira ntchito mokhazikika komanso kothandiza

Pofuna kuthana ndi vuto la kutentha kwambiri, LSP-LRS-0310F-04 laser rangefinder imagwiritsa ntchito njira yapamwamba yochepetsera kutentha. Mwa kukhathamiritsa njira yopangira kutentha kwamkati, kuonjezera malo otenthetsera kutentha ndikugwiritsa ntchito zida zotenthetsera kutentha kwambiri, mankhwalawa amatha kutulutsa mwachangu kutentha kwamkati komwe kumapangidwa, kuonetsetsa kuti zigawo zikuluzikulu zimatha kukhalabe ndi kutentha koyenera kwa ntchito pansi pa katundu wanthawi yayitali. ntchito. Kuthekera kwabwino kwambiri kwa kutentha kumeneku sikungowonjezera moyo wautumiki wa mankhwalawo, komanso kumatsimikizira kukhazikika ndi kusasinthasintha kwa magwiridwe antchito osiyanasiyana.

* Kusunthika ndi kulimba: kapangidwe ka miniaturized, magwiridwe antchito abwino kwambiri amatsimikizika

LSP-LRS-0310F-04 laser rangefinder imadziwika ndi kukula kwake kodabwitsa (ma gramu 33 okha) ndi kulemera kwake, poganizira za khalidwe labwino kwambiri la machitidwe okhazikika, kukana kwakukulu ndi chitetezo cha maso choyamba, kusonyeza bwino kwambiri. mgwirizano pakati pa kunyamula ndi kukhazikika. Mapangidwe a mankhwalawa akuwonetsa bwino kumvetsetsa kwakuya kwa zosowa za ogwiritsa ntchito komanso kuchuluka kwakukulu kwa kuphatikiza kwaukadaulo waukadaulo, kukhala chidwi kwambiri pamsika.

04 Ntchito Scenario

Amagwiritsidwa ntchito m'magawo ambiri apadera monga kusaka ndi kusiyanasiyana, malo opangira ma photoelectric, ma drones, magalimoto opanda anthu, ma robotiki, njira zoyendera zanzeru, kupanga mwanzeru, mayendedwe anzeru, kupanga kotetezeka, ndi chitetezo chanzeru.

* Laser yotulutsidwa ndi gawo loyambira ili ndi 1535nm, yomwe ili yotetezeka kwa anthu. Ngakhale ndi mawonekedwe otetezeka a maso aumunthu, tikulimbikitsidwa kuti tisayang'ane mwachindunji pa laser;

* Mukakonza kufanana kwa nkhwangwa zitatu zowoneka bwino, onetsetsani kuti mwatsekereza lens yolandila, apo ayi chowunikiracho chidzawonongeka kosatha chifukwa cha echo yochulukirapo;

* Module yoyambira iyi ndiyopanda mpweya. Onetsetsani kuti chinyezi cha chilengedwe ndi chochepera 80% ndikusunga chilengedwe kuti chisawononge laser.

* Kusiyanasiyana kwa module yoyambira kumayenderana ndi mawonekedwe amlengalenga komanso mtundu wa zomwe mukufuna. Mitunduyi idzachepetsedwa ndi chifunga, mvula ndi mphepo yamkuntho. Zolinga monga masamba obiriwira, makoma oyera, ndi miyala yamchere yowonekera imakhala ndi maonekedwe abwino ndipo imatha kuonjezera kusiyana. Kuonjezera apo, pamene chandamale chofuna kupendekera ku mtengo wa laser chikuwonjezeka, mtunduwo udzachepetsedwa;

* Ndizoletsedwa kuwombera laser pazifukwa zowunikira zolimba monga galasi ndi makoma oyera mkati mwa mita 5, kuti tipewe echo kukhala yamphamvu kwambiri ndikuwononga chowunikira cha APD;

* Ndizoletsedwa kulumikiza kapena kutulutsa chingwe mphamvu ikayatsidwa;

* Onetsetsani kuti polarity yamagetsi imalumikizidwa bwino, apo ayi zingayambitse kuwonongeka kwa chipangizocho.
