i-accelerometer

Kungenxa yoko le nto i-accelerometers ngabahlobo abalungileyo be-gyroscopes: kuba banokubona izikhombisi ezibalaseleyo "ezantsi" (ubuncinci, xa zikwimeko yomxhuzulane womhlaba).

Ewe, ngokuthetha ngokubanzi. Ukusuka komnye umzuzu ukuya komnye, ifumana umxhuzulane, ukukhawulezisa komgca, amandla e-centrifugal aveliswa kukujikeleza, ukungcangcazela, ingxolo kwaye, ngokuqinisekileyo, iziphene zenzwa.

Ngoko ke, nangona izinga eliphezulu lesampuli kunye nokuchaneka okulungileyo kwee-sensors ze-MEMS (ngokuqhelekileyo zilungile njenge-gyroscopes), idatha ye-accelerometer iseyenye yedatha enomsindo kwaye engathembekanga. Ifumene "iimpawu" ezininzi ekufuneka zingacaciswanga. Kodwa luvakalelo kuyo yonke le miqondiso yahlukileyo eyenza ukuba ibe yendalo yonke-ikuva yonke into.

Kukho amanyathelo amabini okudibanisa okukhawulezisa ukusuka kwindawo esifuna ukuyazi ngokwenene, ngoko kufuneka sishwankathele i-deltas eninzi kunye nemigca yempazamo, ukusuka kwisantya esilinganisiweyo ukuya kwisantya esiqikelelweyo, kwaye ke kufuneka siyenze kwakhona ukuze sifumane uqikelelo. isikhundla. Iimpazamo zihlala zisanda.

Kungenxa yoko le nto i-GPS ingumhlobo we-accelerometer: kuba iya "zero" impazamo yendawo eyandayo ngamaxesha athile, kanye njengoko i-accelerometer isusa ngobunono impazamo ye-azimuth yegyroscope.

imagnetometer

Ikhampasi elungileyo ayifanele ingahoywa. Nangona kunjalo, njenge-accelerometer, ihlala isetyenziswa njengendlela yokulawula ixesha elide le-gyro drift. Ukwazi ukuba leliphi icala elingasentla kubaluleke ngakumbi kunokwazi ukuba leliphi icala elikumagnethi emantla-kodwa ngezi zimbini, siyakwazi ukukwazi ukuma kwethu okuhle ngokwenene emhlabeni.

Bahlala bedityaniswa nabamkeli beGPS, kuba baphinda balwe nobuthathaka obukhulu bomnye nomnye, kodwa bahambelana ngokusondeleyo kweminye imiba. Enye inika indawo egqwethekileyo, kwaye enye inika umkhombandlela ogqwesileyo.
