Momwe Ma Drone Injini Amagwirira Ntchito ndi Ntchito Zawo
Ma drone—kapena magalimoto amlengalenga opanda anthu (UAVs)—akuchulukirachulukira, kuyambira kujambula zithunzi zamasewera mpaka kuyang'anira ulimi kwakukulu. Ngakhale kuti ali ndi mawonekedwe ocheperako, ma drone ndi ophatikizana a makina, zamagetsi, ndi mapulogalamu omwe amagwira ntchito limodzi kuti akwaniritse kuuluka kokhazikika, kuyankha malamulo, ndikuchita ntchito zinazake. Nkhaniyi ikufotokoza momwe "mainjini" a ma drone (ponena za makina oyendetsa ndi makina owongolera ndege) amagwirira ntchito komanso ntchito zawo zazikulu m'magawo osiyanasiyana.
1. Zigawo zazikulu zomwe zimapangitsa kuti drone iwuluke
Kuti drone iwuluke, pali zinthu zingapo zofunika zomwe zimagwirizana:
1. Chimango
Kapangidwe kake kamene kamathandizira zigawo zonse. Kapangidwe kake nthawi zambiri kamakhala pulasitiki yophatikizika, ulusi wa kaboni, kapena aluminiyamu yopepuka. Kapangidwe ka chimango kamakhudza kayendedwe ka mpweya, kulimba, ndi mphamvu ya katundu.
2. Mota
Ma drone ambiri a multirotor amagwiritsa ntchito ma mota opanda maburashi chifukwa ndi othandiza, amphamvu, komanso osakonza bwino. Ma mota amenewa ndi omwe amachititsa kuti ma propeller apange mphamvu.
3. Chonyamulira
Choponderacho chimasintha kuzungulira kwa injini kukhala mpweya wotsikira pansi, zomwe zimapangitsa kuti chikwezedwe. Kukula ndi kukwera kwa choponderacho kumakhudza magwiridwe antchito, kusuntha, ndi kugwiritsa ntchito mphamvu.
4. ESC (Wowongolera Liwiro Lamagetsi)
ESC ndi "chowongolera mphamvu" cha mota. Chowongolera ndege chimatumiza chizindikiro ku ESC, chomwe chimawongolera mphamvu yamagetsi kupita ku mota, ndikuwonjezera kapena kuchepetsa ma revs ake molondola.
5. Batri
Mabatire a LiPo (Lithium Polymer) nthawi zambiri amagwiritsidwa ntchito chifukwa amatha kupereka mafunde amphamvu. Mphamvu (mAh), voteji (monga 3S/4S/6S), ndi C rating zimatsimikiza nthawi youluka komanso momwe imagwirira ntchito.
6. Woyang'anira Ndege (FC)
Uwu ndi "ubongo" wa drone. FC imalandira deta ya sensa (gyroscope, accelerometer, barometer, magnetometer), imaigwiritsa ntchito, kenako imatulutsa malamulo ku ESC/motor kuti ikhazikitse drone ndikuyenda motsatira zomwe zalowetsedwa.
7. Zosewerera zoyendera ndi malo
– IMU (Inertial Measurement Unit): kuphatikiza kwa gyroscope ndi accelerometer kuti muwerenge kayendedwe ndi kupendekera.
– GPS/GLONASS/Galileo: imazindikira malo ndipo imathandizira ndi njira zoyendetsera ndege zokha monga kubwerera kunyumba.
– Barometer: imathandiza kusunga mtunda.
– Kampasi (magnetometer): imathandiza kuyang'ana komwe kuli.
8. Njira yolumikizirana
- Kuwongolera kutali (RC link): tumizani malamulo oyendetsa.
– Chotumizira kanema / ulalo wa digito: wa FPV (Kuwona Munthu Woyamba).
- Telemetry: imatumiza deta monga batri, kutalika, liwiro, ndi malo.
9. Malipiro
Ikhoza kukhala kamera, gimbal, multispectral sensor, lidar, speaker, kapena ngakhale makina opopera/otsitsa.
2. Mfundo zoyambira zoyendetsera ndege ya multirotor drone
Ma drone a multirotor (quad, hexa, octo) amauluka powongolera liwiro lozungulira la injini iliyonse. Mosiyana ndi ndege zokhala ndi mapiko okhazikika, zomwe zimadalira mapiko kuti zipange kukweza ndege pouluka, ma multirotor amapanga kukweza ndege pafupifupi kwathunthu kuchokera ku propeller thrust.
Mayendedwe anayi akuluakulu a drone amafotokozedwa ndi kusintha kwa kayendedwe ka injini:
– Kunyamuka/kukwera: ma mota onse amafulumizitsidwa kuti mphamvu yonse yokweza ifike > kulemera kwa drone.
– Pansi: ma mota amachepetsedwa kuti mphamvu yokweza < kulemera kwa drone. - Pitch (kutsogolo/kumbuyo): ma mota akutsogolo ndi kumbuyo amayikidwa pa liwiro losiyana, kotero drone imapendekeka ndikuyenda patsogolo kapena kumbuyo. - Gubuduza (kumanzere/kumanja): ma mota akumanzere ndi kumanja amayikidwa pa liwiro losiyana kuti drone ipendekeke mbali ina. - Yaw (kuzungulira pamalo): ma mota awiriawiri ozungulira mozungulira ndi motsutsa wotchi amayikidwa kuti akhale ndi ma thrust osiyanasiyana, ndikupanga mphindi yozungulira kotero drone imazungulira. Chinsinsi cha kukhazikika kwa drone ndikuwongolera mwachangu kwambiri. Wowongolera ndege amapanga zosintha makumi mpaka mazana pa sekondi (kutengera ma loops owongolera monga PID), kuonetsetsa kuti drone imakhalabe yolinganizika ngakhale ikakumana ndi mphepo kapena kusintha kwa katundu. 3. Momwe "injini" ya drone imagwirira ntchito: kuyambira kulamula kupita ku kayendedwe ka injini Mawu oti "injini" mu ma drone nthawi zambiri amatanthauza makina oyendetsa (motor + propeller + ESC) ndi makina owongolera omwe amawongolera. Kayendedwe ka ntchito ndi motere: 1. Woyendetsa ndege kapena ntchito yodziyimira payokha imapereka lamulo. Lamuloli likhoza kuchokera ku remote stick (manual), waypoint (automatic), kapena mission software (monga mapu). 2. Flight controller imawerenga ma FC sensors ndipo nthawi zonse imayerekeza momwe drone ilili panopa (tilt angle, acceleration, heading, level, GPS position) ndi cholinga chomwe mukufuna. 3. Njira yokhazikika imawerengera kusintha. Mwachitsanzo, ngati drone ipendekeka kumanja chifukwa cha mphepo yamkuntho, FC imawerengera kusintha kuti iwonjezere kugwedezeka kumbali imeneyo kuti ibwezeretse kukhazikika.
4. FC imatumiza chizindikiro ku ESC. Chizindikirocho chingakhale PWM, OneShot, DShot, kapena protocol ina. Lamuloli limatsimikiza momwe injini iyenera kuzungulirira mofulumira. 5. ESC imawongolera mphamvu yamagetsi kupita ku injini yopanda burashi. Ma mota opanda burashi amagwira ntchito ndi maginito "ozungulira" amagetsi. ESC imapereka mphamvu mwanjira inayake kuti izungulire rotor bwino komanso molondola. 6. Propeller imapanga mphamvu. Kuzungulira kwa injini kumayendetsa propeller, kukankhira mpweya pansi, kupanga kukweza ndi kuyendetsa ngati pakufunika. Zonsezi zimabwerezabwereza pakapita nthawi yochepa kwambiri, kotero drone imawoneka kuti "ikuyenda mozungulira" pomwe kwenikweni ikupanga ma micro-corrections nthawi zonse. 4. Kuyang'anira mphamvu ndi zinthu zomwe zimakhudza nthawi youluka. Mphamvu ndiye chinthu chachikulu choletsa ma drone. Kutalika kwa ulendo kumakhudzidwa ndi: - Mphamvu ya batri ndi magwiridwe antchito a motor-propeller. Propeller yoyenera imatha kusunga mphamvu zambiri. - Kulemera konse. Mota ikalemera (mwachitsanzo, kunyamula kamera yayikulu), mphamvu yochulukirapo imafunika, imakhala yowononga kwambiri. - Mphepo ndi kalembedwe ka ndege. Kuuluka mwamphamvu, ndi kuthamanga kwambiri, kapena motsutsana ndi mphepo kudzatulutsa batri mwachangu. - Kutentha. Mabatire a LiPo nthawi zambiri sagwira ntchito bwino kutentha kotsika. Ma drone aukadaulo nthawi zambiri amakhala ndi njira zowunikira mabatire ndi kuwerengera kuti awerengere nthawi yotsala youluka kuti oyendetsa ndege athe kubwerera kunyumba asanafike mphamvu yofunikira. 5. Njira zoyendera ndi zodziyimira pawokha Ma drone amakono ali ndi njira zosiyanasiyana zoyendera, mwachitsanzo: - Stabilize/Angle mode: drone imasunga kupendekera kodziyimira pawokha, koyenera oyamba kumene. - Kugwira pamalo: kumasunga malo pamalo enaake. - Kugwira malo (GPS): kumasunga malo pamalo enaake. - Kubwerera-Kunyumba (RTH): kumabwerera pamalo onyamuka chizindikiro chikatayika kapena batire ili yotsika. - Ntchito ya Waypoint: imauluka m'njira ya malo olumikizirana. Makina oyendetsera awa ndi omwe amapangitsa ma drone kukhala chida chogwirira ntchito, osati chidole chokha. 6. Kugwiritsa ntchito ma drone m'magawo osiyanasiyana 1) Kujambula ndi kujambula mavidiyo Ma drone amanyamula makamera okhala ndi ma gimbals kuti apange zithunzi zokhazikika kuchokera mlengalenga. Amagwiritsidwa ntchito pamafilimu, zotsatsa, zolemba zochitika, ndi zinthu zapaintaneti. Ubwino wake ndi wakuti amatha kukwaniritsa ma angles omwe kale anali ovuta/okwera mtengo kukwaniritsa. 2) Kujambula Mapu ndi Kufufuza Ndi makamera apamwamba kwambiri kapena masensa apadera, ma drone amatha kupanga ma orthomosaics, mitundu ya 3D, ndi mamapu a contour. Ntchito zake zikuphatikizapo: - kafukufuku wa malo ndi malo, - kuyeza kuchuluka kwa migodi, - kukonzekera zomangamanga.
3) Ulimi wolondola Ma drone amatha kuyang'anira thanzi la mbewu pogwiritsa ntchito makamera ambiri (monga NDVI), kuzindikira madera omwe madzi akusowa, kufalikira kwa tizilombo, kapena kusowa kwa michere. Palinso ma drone opopera omwe amathandiza kugawa mankhwala ophera tizilombo/feteleza mosamala kwambiri. 4) Kuyang'anira zomangamanga Ma drone amagwiritsidwa ntchito kuyang'ana: - nsanja zolumikizirana, - zingwe zamagetsi, - milatho, - kumanga madenga, - ma turbine amphepo. Izi zimachepetsa chiopsezo kwa ogwira ntchito ndikufulumizitsa njira yowunikira. 5) Kusaka ndi kupulumutsa (SAR) ndi kuchepetsa masoka Ma drone okhala ndi makamera otentha amatha kusaka ozunzidwa m'malo akuluakulu, kuphatikiza usiku kapena m'malo okhala ndi utsi. Pa kusefukira kwa madzi/kugwa kwa nthaka, ma drone amathandiza kupanga mapu mwachangu komanso kuwunika kuwonongeka. 6) Chitetezo ndi kuyang'anira Pakuyendayenda m'malo opangira mafakitale, minda, kapena malire, ma drone amatha kuyang'anira nthawi zonse. Komabe, chinsinsi ndi malamulo ziyenera kuganiziridwa. 7) Kayendetsedwe ka zinthu ndi kutumiza M'mayiko angapo, ma drone akuyamba kuyesedwa kuti aone ngati katundu wopepuka waperekedwa (mankhwala, zitsanzo za labotale, mapaketi ang'onoang'ono). Mavuto akuphatikizapo chitetezo, njira zamlengalenga, nyengo, ndi zilolezo. 7. Mavuto ndi mbali zachitetezo Ngakhale zili zothandiza, ma drone ali ndi mavuto: - Malamulo oyendetsera ndege: malire okwera, madera oletsedwa, zilolezo zoyendetsera, ndi zofunikira pa woyendetsa ndege. - Chitetezo: chiopsezo cha kugundana, ngozi chifukwa cha kulephera kwa batri, kapena kusokoneza chizindikiro. - Nyengo: mphepo yamkuntho ndi mvula zimakhudza kwambiri kukhazikika. - Zachinsinsi ndi makhalidwe abwino: kugwiritsa ntchito kamera moyenera ndikofunikira. Kugwiritsa ntchito zinthu zotetezeka, kukonza propeller/motor nthawi zonse, kuwerengera masensa, ndi njira zowunikira ndege isanakwere ndikofunikira kwambiri kuti tipewe zochitika. Kutsiliza Momwe injini ya drone imagwirira ntchito kwenikweni ndi njira yolumikizirana pakati pa injini yopanda burashi, propeller, ESC, batri, ndi chowongolera ndege chomwe chimapitiliza kukonza deta ya masensa kuti chikhale chokhazikika. Mothandizidwa ndi GPS, barometer, ndi ma algorithms owongolera, ma drone amatha kuuluka pamanja kapena okha ndikuchita ntchito zosiyanasiyana. Ntchito zawo tsopano zimachokera ku dziko lolenga kupita ku mafakitale - kupanga mapu, ulimi wolondola, kuyang'anira zomangamanga, kusaka ndi kupulumutsa, chitetezo, ndi zinthu. Mtsogolomu, pamene magwiridwe antchito a batri akuwonjezeka, luntha lochita kupanga, ndi malamulo akukhwima, ma drone adzakhala zida zofunika kwambiri pantchito yatsiku ndi tsiku. Ngati mukufuna, nditha kusintha nkhaniyi kuti ikhale yasayansi kwambiri (ndi magawo aukadaulo monga PID, DShot, BLDC commutation) kapena yotchuka kwambiri kwa owerenga ambiri.
