Kwimeko yetekhnoloji eguquka ngokukhawuleza, iyunithi yokulinganisa i-inertial (IMU) izinzwa ziye zaba yinxalenye ebalulekileyo kwizicelo ukusuka kubathengi be-elektroniki ukuya kwiirobhothi eziphambili. I-sensor ye-IMU sisixhobo esiyinkimbinkimbi esenzelwe ukulinganisa i-angle ye-axis ye-axis ye-angular yento kunye nomlinganiselo wayo we-angular kunye nokukhawuleza. Le propati yenza ukuba ibaluleke kakhulu ekusombululeni iingxaki ezintsonkothileyo ezinxulumene nokuhamba, uqhelaniso kunye nolawulo lwentshukumo.
Ukuqulunqwa kunye nomgaqo wokusebenza
IIsivamvo se-IMUubukhulu becala iqulathe amacandelo amabini angundoqo: i-accelerometer kunye ne-gyroscope. Ii-accelerometers zilinganisa ukukhawuleza komgca wento ecaleni kwee-asi ezintathu (X, Y, kunye no-Z). I-Gyroscopes, ngakolunye uhlangothi, ilinganisa isantya se-angular, inika idatha ebalulekileyo malunga nokuhamba okujikelezayo kwento.
Ezi zivamvo zinokusetyenziswa ngabanye okanye ngokudityaniswa ukwenza inkqubo ye-IMU ebanzi kakhulu ezintandathu okanye ezilithoba. Iinkqubo ze-axis ezintandathu ngokuqhelekileyo ziquka ii-accelerometers ezintathu kunye ne-gyroscopes ezintathu, ngelixa iinkqubo ezilithoba ze-axis zongeza i-magnetometers ukunika idatha eyongezelelweyo yokuqhelaniswa. Ngokuqhubekayo ukulinganisa utshintsho kwi-inertia, ii-sensors ze-IMU zinokuqikelela imeko yentshukumo yento, kubandakanywa isikhundla sayo, isantya kunye nesimo sengqondo. Le datha yexesha langempela ibalulekile kwizicelo ezifuna ukulandelela okuchanekileyo kunye nokulawula intshukumo.
Iimeko zesicelo
Abenzi boluvo be-IMUzinezinto ezininzi kwaye zinokusetyenziswa kumashishini ahlukeneyo. Kwicandelo leemoto, badlala indima ebalulekileyo ekwandiseni uzinzo lwezithuthi kunye nokuhamba. Ngokubonelela ngedatha yexesha langempela malunga nolwalathiso lwesithuthi kunye nokukhawuleza, ii-sensors ze-IMU zenza iinkqubo zokuncedisa umqhubi ophezulu (ADAS) zisebenze ngokufanelekileyo, ziphucule ukhuseleko kunye nokusebenza.
Kwiirobhothi, ii-sensors ze-IMU zibalulekile ekugcineni ukulinganisela kunye nokuzinza. Benza iirobhothi ukuba ziqikelele isantya kunye nendlela ezihamba ngayo, ngaloo ndlela ziququzelela ukuma okuchanekileyo kunye nokuhamba. Esi sikhundla sibaluleke kakhulu kwizicelo ezinjengeemoto eziziqhubayo kunye needrones, apho ukunyakaza okuchanekileyo kubalulekile ekusebenzeni ngempumelelo.
Ukongeza, ii-sensors ze-IMU ziya zidityaniswa ngakumbi kwi-elektroniki yabathengi, njengee-smartphones kunye nezixhobo zokudlala. Baphucula amava omsebenzisi ngokuvumela iimpawu ezinjengolawulo olusekwe kwintshukumo kunye nezicelo zokwenyani ezongeziweyo. Kwiinkqubo zokulawula i-industrial, ii-sensors ze-IMU zinceda ukufezekisa i-automation kunye nokusebenza kakuhle, ukuvumela ukubeka iliso olungcono kunye nokulawulwa koomatshini.
Ishishini le-aerospace nalo lizuze kakhulu kubuchwephesha be-IMU. Kwiinqwelo-moya kunye ne-spacecraft, i-sensors ze-IMU zisetyenziselwa ukuhamba kunye nokulawula isimo sengqondo ukuqinisekisa ukuba ezi nqwelo-moya ziyakwazi ukusebenza ngokukhuselekileyo nangokufanelekileyo kwiindawo ezinzima.
Isishwankathelo
Kufuphi,Abenzi boluvo be-IMUziitekhnoloji ezisisiseko ezixhasa usetyenziso oluninzi kwiinkalo ezahlukeneyo. Ikhono layo lokulinganisa ukukhawuleza kunye ne-angular velocity ngokuchaneka okuphezulu kwenza kube sisixhobo esibalulekileyo sokuhamba, ukuqhelaniswa kunye nokulawula ukunyakaza. Njengoko iteknoloji iqhubela phambili, indima ye-IMU sensors iya kuba yinto evelele ngakumbi, ukuqhuba izinto ezintsha kunye nokuphucula ukusebenza kwezixhobo zanamhlanje. Ingaba kwiinkqubo zeemoto, iirobhothi, i-electronics yabathengi okanye i-aerospace, ii-sensors ze-IMU ziya kuhlala zihamba phambili kuphuhliso lwezobuchwepheshe ukudala ihlabathi elihlakaniphile, elidibeneyo.
