Kugwiritsa ntchito IMU mu ma UAV: ​​Kuwongolera kulondola kwandege ndi kukhazikika

M'gawo lomwe likukula mwachangu la magalimoto osayendetsedwa ndi ndege (UAVs), ma inertiaal measurement units (IMUs) amawonekera ngati chigawo chachikulu chothandizira kuyendetsa bwino kwa ndege komanso kuyenda bwino. Pomwe kufunikira kwa ma drones kukupitilira kukula m'mafakitale kuyambira paulimi mpaka kuunika, kuphatikiza kwaukadaulo wapamwamba wa IMU kumakhala kofunika kwambiri. Nkhaniyi ikufotokoza za udindo wofunikira wa ma IMU mu ma drones, kuwonetsa momwe amathandizira pakuthawira kokhazikika, kuyenda bwino komanso kupewa zopinga.

Pamtima pa drone iliyonse yogwira ntchito kwambiri ndi IMU, msonkhano wovuta kwambiri wa masensa omwe amayesa mosamala ndikulemba maulendo atatu a drone. Mwa kuphatikiza ma gyroscopes, accelerometers ndi magnetometers, IMU imapereka chidziwitso chofunikira pamalingaliro a drone, kuthamanga komanso kuthamanga kwa angular. Chidziwitsochi sichimangowonjezera chidziwitso; m'pofunika kuonetsetsa ndege bata ndi kuyenda mogwira mtima. IMU imagwira ntchito ngati ubongo wa drone, kukonza deta yeniyeni yeniyeni ndikudziwitsa kayendetsedwe ka kayendetsedwe ka ndege, kulola kugwira ntchito mopanda malire m'madera osiyanasiyana.

Chimodzi mwazinthu zodziwika bwino za IMU ndikutha kupereka chidziwitso munthawi yeniyeni. IMU imawonetsetsa kuti drone imasunga njira yokhazikika yowulukira poyesa kutalika kwa phula, ngodya yopukutira ndi mbali ya yaw ya drone. Kutha kumeneku kumakhala kofunikira makamaka pazovuta monga mphepo yamkuntho kapena chipwirikiti, pomwe ngakhale kupatuka pang'ono kumatha kubweretsa zolakwika zazikulu pakuyenda. Ndi miyeso yolondola ya IMU, oyendetsa ndege amatha kukhala ndi chidaliro kuti ma drones awo azigwira ntchito modalirika ngakhale pakavuta kwambiri.

Kuphatikiza apo, IMU imagwiranso ntchito yofunikira pothandizira kuyenda. Zikaphatikizidwa ndi masensa ena monga GPS, zomwe zimaperekedwa ndi IMU zimakulitsa luso la drone kuti lidziwe pomwe ili komanso momwe ikuzungulira molondola kwambiri. Kugwirizana pakati pa IMU ndi ukadaulo wa GPS kumathandizira kuyenda bwino, kulola ma drones kuti azitha kuyendetsa bwino maulendo apaulendo ndi mautumiki. Kaya akulemba mapu a minda yayikulu kapena kuyang'anira ndege, ma IMU amaonetsetsa kuti ma drones akuyenda bwino ndikupereka zotsatira zomwe zimakwaniritsa kapena kupitilira zomwe amayembekeza.

Kuphatikiza pakuyenda, IMU imathandizira kupewa zopinga komanso kuyendetsa ndege mokhazikika. Deta yopangidwa ndi IMU imalowetsedwa mu algorithm yowongolera ndege, kulola drone kuzindikira ndikupewa zopinga munthawi yeniyeni. Kutha kumeneku ndikofunikira pamapulogalamu monga ntchito zoperekera, pomwe ma drones amayenera kuyenda m'matauni odzaza ndi nyumba, mitengo ndi zoopsa zina. Pogwiritsa ntchito deta yochokera ku IMU, drone ikhoza kupanga zisankho zachiwiri-pawiri kuti asinthe njira yake yowulukira, kuonetsetsa chitetezo ndi mphamvu.

Masensa apamwamba mkati mwa IMU, kuphatikiza masensa a MEMS ndi ma axis gyroscopes atatu, ndizofunikira kwambiri pakukwaniritsa izi. Masensa a MEMS amagwiritsa ntchito makina ang'onoang'ono kuti athe kuyeza kuthamanga komanso kuthamanga kwa angular, pamene ma gyroscopes atatu-axis amajambula kusuntha kwa drone m'miyeso itatu. Pamodzi, zigawozi zimapanga dongosolo lamphamvu lomwe limalola kuti drone igwire ntchito mosayerekezeka komanso yodalirika.

Mwachidule, ntchito yaIMUteknoloji pa drones idzasintha malamulo a makampani. IMU imathandizira magwiridwe antchito onse a drone popereka chidziwitso chofunikira pakuthawira kokhazikika, kuyenda bwino komanso kupewa zopinga. Pamene msika wa drone ukukulirakulira, kuyika ndalama muukadaulo wapamwamba wa IMU mosakayikira kukhala chinthu chofunikira kwambiri pakukwaniritsa bwino ntchito ndikukwaniritsa zosowa zosiyanasiyana zamafakitale osiyanasiyana. Landirani tsogolo la ndege ndi ma drones okhala ndi IMU ndikuwona kusiyana kolondola komanso kukhazikika komwe kumabweretsa.
