Mundima iri kukurumidza kukura yemotokari dzemuchadenga dzisina kurongwa (UAVs), inertial measurement units (IMUs) inomira sechinhu chinokosha chekuvandudza kushanda kwendege uye kufamba kwakarurama. Sezvo kudiwa kwema drones kuri kuramba kuchikwira mumaindasitiri kubva pakurima kusvika pakuongorora, kubatanidzwa kwehunyanzvi hweIMU tekinoroji kuri kuwedzera kukosha. Ichi chinyorwa chinoongorora basa rakakosha reIMUs mumadrones, kuratidza mabatiro avanoita kubhururuka kwakadzikama, kufamba chaiko uye kudzivirira zvipingamupinyi.
Pamwoyo weyese yepamusoro-inoshanda drone ndeye IMU, yakaoma sensor musangano inonyatso kuyera uye inorekodha drone's three-dimensional motion. Nekubatanidza gyroscopes, accelerometers uye magnetometers, IMU inopa data rakakosha pamaitiro eiyo drone, kukurumidza uye angular velocity. Mashoko aya haasi mashoko okuwedzera; zvakakosha kuti uve nechokwadi chekubhururuka kwakadzikama uye kufamba kunoshanda. Iyo IMU inoshanda sehuropi hweiyo drone, kugadzirisa data-chaiyo-nguva uye kuzivisa iyo ndege yekudzora hurongwa, ichibvumira kushanda kusina musono munzvimbo dzakasiyana siyana.
Chimwe chezvinhu zvakatanhamara zveIMU kugona kwayo kupa ruzivo rwechokwadi rwenguva. IMU inova nechokwadi chekuti drone inochengetedza nzira yekubhururuka yakagadzikana nekuyera pitch angle, roll angle uye yaw angle yedrone. Kugona uku kunonyanya kukosha mumamiriro ezvinhu akaoma akadai semhepo ine simba kana mhirizhonga, apo kunyange kutsauka kuduku kunogona kutungamirira kuzvikanganiso zvakakomba zvekufambisa. Nezviyero zveIMU chaizvo, vanofambisa drone vanogona kuva nechivimbo chekuti drones yavo ichashanda zvakavimbika kunyangwe mumamiriro ezvinhu anonetsa.
Pamusoro pezvo, IMU inoitawo basa rakakosha mukubatsira kufamba. Kana yasanganiswa nemamwe masensa akadai seGPS, iyo data yakapihwa neIMU inosimudzira kugona kweiyo drone kuona nzvimbo yayo uye kutaridzika kwayo nekunyanya kukwirira. Kubatana pakati peIMU neGPS tekinoroji inogonesa kufamba chaiko, zvichibvumira drones kuita nyore nyore nzira dzakaoma dzekubhururuka nemamishini. Kungave kugadzira maturakiti makuru eminda yepurazi kana kuita ongororo yemuchadenga, maIMU anovimbisa kuti drones inogara panzira uye inounza mibairo inosangana kana kudarika zvinotarisirwa.
Pamusoro pekufamba, IMU inobatsira kudzivirira zvipingamupinyi uye kuchengetedza ndege yakagadzikana. Iyo data inogadzirwa neIMU inodyiswa mune yekudzora ndege algorithm, ichibvumira iyo drone kuona uye kudzivirira zvipingamupinyi munguva chaiyo. Kugona uku kwakakosha kune zvikumbiro zvakaita sekutumira masevhisi, uko madrones anofanirwa kufamba munzvimbo dzemudhorobha dzakazadzwa nezvivakwa, miti uye dzimwe njodzi dzinogona kuitika. Nekushandisa data kubva kuIMU, iyo drone inogona kuita kupatsanura-yechipiri sarudzo kuti ichinje nzira yayo yekubhururuka, kuve nechokwadi chekuchengeteka uye kushanda zvakanaka.
Masensor epamberi mukati meIMU, anosanganisira MEMS sensors uye matatu-axis gyroscopes, akakosha pakuita izvi zvinoshamisa kugona. Masensa eMEMS anoshandisa zvimiro zvidiki zvemuchina kuyera kumhanyisa uye angular velocity, nepo matatu-axis gyroscopes inobata kutenderera kweiyo drone mumativi matatu. Pamwe chete, zvikamu izvi zvinoumba hurongwa hune simba hunobvumira drone kuti ishande nekururama kusingaenzaniswi uye kuvimbika.
Muchidimbu, kushandiswa kweIMUtekinoroji pane drones ichachinja mitemo yeindasitiri. IMU inosimudzira kuita kwese kweiyo drone nekupa dhata inodiwa yekubhururuka kwakadzikama, kunyatso fambisa uye kunoshanda kudzivirira zvipingamupinyi. Sezvo musika we drone uchiramba uchikura, kudyara mutekinoroji yeIMU yepamberi pasina mubvunzo ichave chinhu chakakosha mukubudirira kwekushanda uye kusangana nezvinodiwa zvakasiyana zvemaindasitiri akasiyana. Gamuchira remangwana rekubhururuka neIMU-equipped drones uye uwane mutsauko mukurongeka uye kugadzikana kunounzwa nemhepo.
