Kufika kwatsopano - gawo la 1535nm Erbium laser rangefinder

01 Chiyambi

M'zaka zaposachedwapa, chifukwa cha kubuka kwa nsanja zankhondo zopanda anthu, ma drone ndi zida zonyamulika za asilikali pawokha, zida zazing'ono zogwiritsidwa ntchito ndi laser rangefinder zazitali zawonetsa kuthekera kwakukulu kogwiritsa ntchito. Ukadaulo wa laser wagalasi wa Erbium wokhala ndi kutalika kwa 1535nm ukukulirakulira. Uli ndi ubwino wotetezeka maso, mphamvu yayikulu yolowa mu utsi, komanso kutalika kwa mtunda wautali, ndipo ndiye njira yofunika kwambiri pakukula kwa ukadaulo wa laser rangeing.

02 Chiyambi cha Zamalonda

LSP-LRS-0310 F-04 laser rangefinder ndi laser rangefinder yopangidwa kutengera laser yagalasi ya 1535nm Er yopangidwa yokha ndi Lumispot. Imagwiritsa ntchito njira yatsopano yosinthira nthawi ya ndege (TOF), ndipo magwiridwe ake osinthira ndi abwino kwambiri pamitundu yosiyanasiyana ya zolinga - mtunda wa nyumba ukhoza kufika makilomita 5 mosavuta, ndipo ngakhale pamagalimoto othamanga, imatha kufikira makilomita 3.5 okhazikika. Muzochitika zogwiritsira ntchito monga kuyang'anira antchito, mtunda wa anthu ndi woposa makilomita awiri, kuonetsetsa kuti deta ndi yolondola komanso yeniyeni. LSP-LRS-0310F-04 laser rangefinder imathandizira kulumikizana ndi kompyuta yolandirira kudzera pa RS422 serial port (ntchito yosinthira madoko a TTL serial imaperekedwanso), zomwe zimapangitsa kutumiza deta kukhala kosavuta komanso kogwira mtima.

* Kapangidwe kophatikizana ka kukula kwa denga: kuphatikiza bwino komanso kusinthasintha kwachilengedwe

Kapangidwe kowonjezera kwa beam kophatikizana kumatsimikizira kulumikizana kolondola komanso mgwirizano wabwino pakati pa zigawozo. Gwero la pampu ya LD limapereka mphamvu yokhazikika komanso yothandiza ya laser medium, fast axis collimator ndi focusing mirror zimawongolera molondola mawonekedwe a beam, gain module imakulitsa mphamvu ya laser, ndipo beam expander imakulitsa bwino m'mimba mwake wa beam, imachepetsa ngodya yosiyana ya beam, ndikukweza kuwongolera kwa beam ndi mtunda wotumizira. Optical sampling module imayang'anira magwiridwe antchito a laser nthawi yeniyeni kuti iwonetsetse kuti kutulutsa kokhazikika komanso kodalirika kukuchitika. Nthawi yomweyo, kapangidwe kotsekedwa ndi kotetezeka ku chilengedwe, kumawonjezera moyo wa ntchito ya laser, ndikuchepetsa ndalama zosamalira.

Chithunzi 2 Chithunzi chenicheni cha laser yagalasi ya erbium

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

Njira yosinthira magawo imatengera muyeso wolondola ngati maziko ake. Mwa kukonza kapangidwe ka njira yowunikira ndi ma algorithm apamwamba opangira ma signal, kuphatikiza mphamvu yayikulu yotulutsa komanso mawonekedwe a pulse yayitali ya laser, imatha kulowa bwino mumlengalenga ndikuwonetsetsa kuti zotsatira zoyezera zimakhala zokhazikika komanso zolondola. Ukadaulo uwu umagwiritsa ntchito njira yosinthira ma frequency ambiri kuti itulutse ma pulse angapo a laser ndikusonkhanitsa ndikugwiritsa ntchito ma echo signals, kuletsa bwino phokoso ndi kusokoneza, kukonza kwambiri chiŵerengero cha chizindikiro-kwa-phokoso, ndikukwaniritsa muyeso wolondola wa mtunda womwe mukufuna. Ngakhale m'malo ovuta kapena pakagwa kusintha pang'ono, njira zosinthira magawo zimatha kutsimikizira kulondola ndi kukhazikika kwa zotsatira zoyezera, kukhala njira yofunika kwambiri yowongolera kulondola kwa magawo.

*Chiwembu cha double threshold chimakwaniritsa kulondola kwa mitundu yosiyanasiyana: kuwerengera kawiri, kupitirira kulondola kokwanira

Pakatikati pa dongosolo la magawo awiri pali njira yake yowerengera kawiri. Dongosololi limayika malire awiri osiyana a chizindikiro kuti ligwire mfundo ziwiri zofunika kwambiri za chizindikiro cha echo. Mfundo ziwirizi zimasiyana pang'ono chifukwa cha malire osiyanasiyana, koma kusiyana kumeneku ndi komwe kumakhala chinsinsi chobwezera zolakwika. Kudzera mu kuyeza nthawi molondola komanso kuwerengera, dongosololi limatha kuwerengera molondola kusiyana kwa nthawi pakati pa mfundo ziwirizi munthawi, ndikulinganiza bwino zotsatira zoyambirira moyenerera, motero limasintha kwambiri kulondola kwa malire.

Chithunzi 3 Chithunzi cha ndondomeko ya njira yowerengera kulondola kwa njira ziwiri zolipirira

* Kapangidwe kogwiritsa ntchito mphamvu zochepa: kugwira ntchito bwino kwambiri, kupulumutsa mphamvu, magwiridwe antchito abwino

Kudzera mu kukonza bwino ma module a circuit monga bolodi lalikulu lowongolera ndi bolodi loyendetsa, tagwiritsa ntchito ma chip apamwamba amphamvu zochepa komanso njira zoyendetsera bwino mphamvu kuti tiwonetsetse kuti mu standby mode, kugwiritsa ntchito mphamvu ya dongosolo kumayendetsedwa mosamala pansi pa 0.24W, zomwe ndi kuchepa kwakukulu poyerekeza ndi mapangidwe achikhalidwe. Pafupipafupi ya 1Hz, kugwiritsa ntchito mphamvu konse kumasungidwa mkati mwa 0.76W, kuwonetsa kugwiritsa ntchito bwino mphamvu. Pa nthawi yogwira ntchito kwambiri, ngakhale kuti kugwiritsa ntchito mphamvu kudzawonjezeka, kumayendetsedwabe bwino mkati mwa 3W, kuonetsetsa kuti zida zikugwira ntchito bwino pansi pa zofunikira zapamwamba poganizira zolinga zosungira mphamvu.

* Kugwira ntchito molimbika kwambiri: kutentha kwambiri, kuonetsetsa kuti ntchito yake ndi yokhazikika komanso yothandiza

Pofuna kuthana ndi vuto la kutentha kwambiri, chipangizo cha laser cha LSP-LRS-0310F-04 chimagwiritsa ntchito njira yapamwamba yochotsera kutentha. Mwa kukonza njira yotulutsira kutentha mkati, kuwonjezera malo ochotsera kutentha komanso kugwiritsa ntchito zipangizo zochotsera kutentha bwino, chinthucho chimatha kuchotsa kutentha kwamkati mwachangu, kuonetsetsa kuti zigawo zazikulu zimatha kusunga kutentha koyenera pansi pa ntchito yayitali. Mphamvu yabwino kwambiri yochotsera kutentha sikuti imangowonjezera moyo wa ntchito ya chinthucho, komanso imatsimikizira kukhazikika ndi kusinthasintha kwa magwiridwe antchito osiyanasiyana.

* Kusunthika ndi kulimba: kapangidwe kakang'ono, magwiridwe antchito abwino kwambiri otsimikizika

Chojambulira cha laser cha LSP-LRS-0310F-04 chimadziwika ndi kukula kwake kochepa kodabwitsa (magalamu 33 okha) komanso kulemera kopepuka, poganizira ubwino wake wokhazikika, kukana kukhudza kwambiri komanso chitetezo cha maso chapamwamba, kusonyeza mgwirizano wabwino pakati pa kusunthika ndi kulimba. Kapangidwe ka chinthuchi kakuwonetsa bwino kumvetsetsa kwakuya kwa zosowa za ogwiritsa ntchito komanso kuphatikiza kwakukulu kwa luso laukadaulo, kukhala chinthu chofunikira kwambiri pamsika.

04 Chitsanzo cha Ntchito

Imagwiritsidwa ntchito m'magawo ambiri apadera monga kuyang'ana ndi kusuntha, malo ogwiritsira ntchito magetsi, ma drones, magalimoto opanda anthu, maloboti, machitidwe oyendera anzeru, kupanga mwanzeru, kukonza zinthu mwanzeru, kupanga motetezeka, komanso chitetezo chanzeru.

06 Malangizo

* Laser yomwe imachokera ku gawo ili ndi 1535nm, yomwe ndi yotetezeka kwa maso a anthu. Ngakhale kuti ndi mafunde otetezeka kwa maso a anthu, tikukulimbikitsani kuti musayang'ane mwachindunji pa laser;

* Mukasintha kufanana kwa ma axes atatu optical, onetsetsani kuti mwatseka lens yolandirira, apo ayi chowunikira chidzawonongeka kwamuyaya chifukwa cha echo yambiri;

* Gawo lozungulira ili sililola mpweya kulowa. Onetsetsani kuti chinyezi cha chilengedwe chili chochepera 80% ndipo sungani chilengedwe kukhala choyera kuti musawononge laser.

* Kuchuluka kwa gawo lozungulira kumakhudzana ndi mawonekedwe amlengalenga ndi mtundu wa cholinga. Kuchuluka kwa chinthucho kudzachepa munthawi ya chifunga, mvula ndi mvula yamchenga. Zolinga monga masamba obiriwira, makoma oyera, ndi miyala yamchere yowonekera zimakhala ndi kuwala kwabwino ndipo zimatha kuwonjezera kuchuluka kwa chinthucho. Kuphatikiza apo, pamene ngodya ya chopingacho ikukwera, kuchuluka kwa chinthucho kudzachepa;

* N'koletsedwa kwambiri kuwombera laser pamalo amphamvu owunikira monga magalasi ndi makoma oyera mkati mwa mamita 5, kuti echo isamveke mwamphamvu kwambiri ndikuwononga chowunikira cha APD;

* N'koletsedwa kwambiri kulumikiza kapena kuchotsa chingwecho magetsi akayaka;

* Onetsetsani kuti polarity yamagetsi yalumikizidwa bwino, apo ayi izi ziwononga chipangizocho kwamuyaya..
