Abstract. Inertial accelerometer sensor record txav Rhythmic thiab repetitive zog yog ib txwm muaj rau yuav luag txhua yam kev ua si nawv. Nws muaj peev xwm ua qauv kev ua kom nrawm nrawm ntawm lub viav vias (ob lub cev thiab siv) siv lub cosine squared muaj nuj nqi ntawm angular txoj hauj lwm nrog lub sij hawm.

Accelerometer siv li cas hauv kev ua kis las?

Lub ntsuas ntsuas nrawm kuj tseem tuaj yeem kuaj pom kev sib tsoouas tuaj yeem yog qhov tseem ceeb hauv kev ua kis las xws li rugby thiab Asmeskas ncaws pob uas cov kws qhia saib xyuas kom ncua sij hawm sib cuag ncaj qha rau lawv cov kis las kis thoob week.

Dab tsi yog accelerometer siv rau hauv kev ua si lub cev?

Accelerometers yog kev txav mus los uas muaj peev xwm ntes kev siv lub cev hnyav … Lub luag haujlwm tseem ceeb ntawm accelerometers yog tias lub sensor hloov txav mus rau hauv hluav taws xob teeb liab (suav) uas yog proportional rau cov leeg nqaij quab yuam tsim tawm (Melanson thiab Freedson, 1996)2

Accelerometer hauv PE yog dab tsi?

Accelerometers yog transducers uas tsim cov hluav taws xob teeb liab tso tawm raws li qhov tshwm sim ntawm cov khoom siv nrawm nrawm rauchav tsev. … PE accelerometers siv cov cuab yeej no los ntawm kev teeb tsa lub zog inertial mus rau piezoelectric siv lead ua.

Accelerometer nws siv li cas?

A accelerometer yog ib qho khoom siv hluav taws xob khoom siv los ntsuas lub zog nrawmCov rog zoo li no yuav zoo li qub, zoo li lub zog txuas ntxiv ntawm lub ntiajteb txawj nqus lossis, zoo li cov ntaub ntawv nrog ntau lub xov tooj ntawm tes, dynamic kom paub txog kev txav los yog kev vibrations. Acceleration yog qhov ntsuas ntawm qhov hloov ntawm qhov nrawm, lossis nrawm muab faib raws sijhawm.
