Ezweni lobuchwepheshe elithuthuka ngokushesha,amayunithi okulinganisa angasebenzi (IMUs)zigqame njengezingxenye ezibalulekile ezinhlelweni ezihlukahlukene kusukela ku-aerospace kuya kumasistimu ezimoto. Lesi sihloko sicubungula inkimbinkimbi ye-IMU, amandla ayo, kanye nendima yayo ebalulekile ekunikezeni izixazululo zesimo sengqondo.
####Iyini i-IMU?
Aniyunithi yokulinganisa inertial (IMU)iyithuluzi eliyinkimbinkimbi elikala amandla athile, izinga le-angular, futhi ngezinye izikhathi amandla kazibuthe azungezile. Ngokuyinhloko isetshenziselwa ukunquma indlela kanye nokunyakaza kwezinto ezisemkhathini we-three-dimensional. I-IMU iwuhlelo lokuzulazula lwe-strapdown inertial, okusho ukuthi ayidingi noma yiziphi izingxenye ezihambayo ukuze zisebenze, okuyenza ihlangane futhi ithembeke.
#### Ingenzani i-IMU?
Ukusebenza kwe-IMU kubanzi kakhulu. Ilandelela ukunyakaza kwezinto, ihlinzeka ngedatha ebalulekile yokuhamba, ukuzinza kanye nezinhlelo zokulawula. Emkhathini, ama-IMU asetshenziswa ezindizeni nasemkhathini ukuze kugcinwe indlela kanye nendlela. Ezinhlelweni zezimoto, zithuthukisa ukuzinza kwemoto namandla okuzulazula, ikakhulukazi ezindaweni lapho amasignali e-GPS engase abe buthaka noma angatholakali khona. Ukwengeza, ama-IMU abalulekile kumarobhothi, into engekho ngokoqobo, namadivayisi eselula, avumela ukulandelela ukunyakaza okunembayo nokusebenzisana komsebenzisi.
#### Iquketheni i-IMU?
I-IMU ngokuvamile iqukethe izingxenye ezintathu eziyinhloko: i-accelerometer, i-gyroscope, futhi ngezinye izikhathi i-magnetometer. Ama-Accelerometer akala ukusheshisa komugqa ngokuhambisana nezimbazo ezintathu (X, Y, no-Z), kuyilapho ama-gyroscopes ekala izinga lokuzungezisa mayelana nalawa ma-ax. Amanye ama-IMU athuthukisiwe ahlanganisa futhi ama-magnetometers ukuze anikeze idatha yokuma eyengeziwe ehlobene nendawo kazibuthe Yomhlaba. Le nhlanganisela yezinzwa yenza i-IMU inikeze idatha egcwele yokunyakaza neyomumo.
####IMU umgomo wokusebenza
Umgomo wokusebenza we-IMU usekelwe ekuhlanganisweni kwedatha yenzwa ngokuhamba kwesikhathi. Ama-Accelerometer athola izinguquko zejubane, kuyilapho ama-gyroscope akala izinguquko endaweni eyi-angular. Ngokuqhubeka nokusampula lezi zilinganiso, i-IMU ingabala indawo yamanje yento nomumo ngokuhlobene nomsuka wayo. Nokho, kubalulekile ukuqaphela ukuthi i-IMU inikeza ulwazi lokuma okuhlobene, okusho ukuthi ilandelela ukunyakaza kusuka kumsuka owaziwayo, kodwa ayinikezi idatha yendawo yonke.
Ukuze kuthuthukiswe ukusebenza kwawo, ama-IMU avame ukuhlanganiswa nobuchwepheshe be-Global Positioning System (GPS). Nakuba i-GPS inikeza ukuma okuphelele, ingase ingathembeki ezindaweni ezithile, njengemihosha yasemadolobheni noma amahlathi aminyene. Kulezi zimo, i-IMU inxephezela ukulahleka kwesignali ye-GPS, ivumela izimoto nezisetshenziswa ukuthi zigcine ukuzulazula okunembile futhi zigweme "ukulahleka."
#### Isifinyezo
Sengiphetha, iiyunithi yokulinganisa inertial (IMU)ubuchwepheshe obubalulekile obudlala indima ebalulekile ekuzulazuleni kwesimanje kanye nezinhlelo zokulandela ukunyakaza. Ngokuhlanganisa ama-accelerometer nama-gyroscopes, ama-IMU ahlinzeka ngedatha ebalulekile yokunquma umumo nokunyakaza kwento. Nakuba ihlinzeka ngolwazi oluhlobene lokuma, ukuhlanganiswa kwayo nobuchwepheshe be-GPS kuqinisekisa ukuthi abasebenzisi bangakwazi ukugcina ukuzulazula okunembile ngisho nasezimweni eziyinselele. Njengoba ubuchwepheshe buqhubeka buthuthuka, ama-IMU azohlala eyinsika yokuthuthukiswa kwezixazululo ezintsha kuzo zonke izimboni, ukuthuthukisa ukuphepha, ukusebenza kahle kanye nolwazi lwabasebenzisi.
Kungakhathaliseki ukuthi usebenza emkhathini, kwezezimoto, noma kumarobhothi, ukuqonda amakhono namakhono e-IMU kubalulekile ukuze uthole amandla ayo aphelele kuhlelo lwakho lokusebenza.
