Mayelana nalolu hlelo lokusebenza

Lolu hlelo lokusebenza oluhambisana nokuvikelwa kwedatha mahhala, olungenazo izikhangiso nolwenzelwe ngokukhethekile izifundo ze-physics. Imiyalo yokuhlola nenguqulo yamadivayisi amadala ingatholakala ku-https: //spaichinger-schallpegelmesser.de. Ulwazi lomzimba lwezinhlelo zokubhekisela luyadingeka ekusebenzeni okulungile nasekuhlolweni kwedatha. Ukuqala isilinganiso, sicela uthephe ku- "Start" bese ku- "Measurement with gravitation" noma ku- "Measurement (indera ethambekele)". Uma isilinganiso singaqali ngaleso sikhathi, i-accelerometer yenziwe yangasebenzi kudivayisi yakho. Lokhu kungalungiswa ngokuvala kuqala ifoni bese uyiqala kabusha ngemuva kwe-approx. Imizuzu emi-5. Lolu hlelo lokusebenza lusebenzisa inzwa yokusheshisa ye-3D ukucacisa i-vector yokusheshisa. Umcibisholo we-vector uboniswa kanye nomcibisholo we-force vector ngesikhathi sangempela ohlelweni lwe-3D lokuxhumanisa. Ngaphezu kwalokho, uhlelo lokusebenza sinquma ijubane kanye isikhundla vector ngokusebenzisa ukuhlanganiswa. Amanani alinganisiwe wezinto zala mavector akhonjiswa kwimidwebo kanye namanani okusheshisa, amanani okushaywa kanye namanani wamandla. Uma i-smartphone noma ithebhulethi inenzwa ye-3D gyro, izivinini ze-angular nazo ziyarekhodwa kusetshenziswa inzwa ye-3D gyro futhi iboniswa njengamagrafu. Ukusebenza okusebenzayo kuhlanganiswe nohlelo lokusebenza ukuhlola wonke amanani alinganisiwe. Lapha, ama-polynomials kusuka ku-0 kuye ku-4 degrees nemisebenzi ye-sine angakhethwa njengemigomo yokusebenza. Ngokuzithandela, ukulungiselelwa kokushaywa kwe-harmonic kungashintshwa ngaphambi noma ngemuva kwesilinganiso. Kulokhu kusebenza, amanani okuqala we-vx (t) ne-sx (t), vy (t) ne-sy (t) noma i-vz (t) ne-sz (t) enzelwa ngokuzenzakalela i-harmonic oscillation kanye ne-low- ukungalungi kokuhlanganiswa kwemvamisa kwenziwa ngokuzenzakalela izihlungi ze-High-pass zisuswa ngokuzenzekelayo, ukuze imidwebo emihle kakhulu nokulingana kwe-sine kukhishwe ngokuvamile. Uhlelo lokusebenza futhi lunesihlungi esiphansi esingasethwa noma sikhanyiswe sicishwe noma ngemuva kwesilinganiso. Lokhu kuvumela ukuphazamiseka kwemvamisa ephezulu njengokudlidliza ukuthi kuhlungwe. Ngaphezu kwalokho, ngemuva kokwenza umsebenzi kufanelekile, ama-tangents kumagrafu wemisebenzi efanelekile sx (t) no-vx (t), sy (t) no-vy (t) noma u-sz (t) no-vz (t) angaboniswa . Lokhu kuyasiza, ngokwesibonelo, ukwenza ubudlelwano phakathi kwe-sx (t), vx (t) ne-ax (t).
Ngaphezu kwalokho, imiphumela yokulinganisa ingagcinwa, ivulwe, ithunyelwe futhi itholwe njengefayela le-CSV. Umkhuba wokulinganisa osebenzayo ongalungisa i-zero offset, amaphutha wokukala, kanye nokungahambisani kahle kwama-eksisi e-accelerometer nakho kuyasetshenziswa. Uyacelwa ukuthi uqaphele ukuthi lokhu kulinganiswa akukwazi ukulungisa umsindo omkhulu wenzwa yokusheshisa, ukuncika kokushisa okungenzeka kanye ne-hysteresis. Lolu hlelo lokusebenza lwenza ukukala okusheshayo nokuhlolwa okulula. Kodwa-ke, ukunemba kwalolu hlelo lokusebenza, ikakhulukazi isivinini kanye nokuthwala isikhundla, kukhawulwe ngamaphutha amakhulu enzwa yokusheshisa. Njengomphumela wokuhlanganiswa noma ukuhlanganiswa okuphindwe kabili, iphutha eliyinsalela elikhona ngemuva kokulinganisa landa ngokulandelana noma ngekota ngokuhamba kwesikhathi. Lokhu ngokuvamile kuholela emaphutheni amakhulu ngejubane nendawo yamanani evela ngemuva kwemizuzwana embalwa. Endabeni yokuhlolwa okuvame ukuba yisikhathi esifushane kakhulu ku-physics, lokhu ngokuvamile akuyona inkinga.
Uma unemibuzo noma uthola amaphutha, ngingajabula ukukuthumela i-imeyili: [e-mail].
