Intshayelelo

Ukufunyanwa kwedatha (i-DAQ) kubhekiselele ekuqokeleleni okuzenzekelayo kokungabikho kwamandla okanye izibonakaliso zamandla ezivela kwi-analog kunye neeyunithi zedijithali ezifana ne-sensor kunye nezinye izixhobo eziza kulinganiswa, kwaye zithunyelwe kwikhompyutheni yokusingatha ukuhlalutya kunye nokusebenza.Inkqubo yokufumana idatha yinkqubo yokulinganisa eguquguqukayo, echazwe ngumsebenzisi edibanisa isofthiwe yokulinganisa kunye neemveliso ze-hardware ezisekelwe kwiikhomputha okanye ezinye iiplatifomu zovavanyo olukhethekileyo.

Ukufunyanwa kwedatha, okwakwaziwa njengokufunyanwa kwedatha, lujongano olusebenzisa isixhobo ukuqokelela idatha ngaphandle kwenkqubo kwaye ifake ngaphakathi kwenkqubo.Itekhnoloji yokufumana idatha isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo.Ngokomzekelo, iikhamera, ii-microphone, zizixhobo zokufumana idatha.

Idatha eqokelelweyo yintlobo yobuninzi bomzimba obuguqulelwe kwiimpawu, ezifana nobushushu, inqanaba lamanzi, isantya somoya, uxinzelelo, njl., ezinokuthi zibe yi-analog okanye idijithali.Ukufumana ngokuqhelekileyo yindlela yokwenza isampuli, oko kukuthi, ukuqokelelwa kwedatha kwinqanaba elifanayo liphinda liphindwe ngamaxesha (okubizwa ngokuba yimijikelo yesampulu).Uninzi lwedatha eqokelelweyo yenzeke ngoko nangoko, kodwa inokuba yi-eigenvalue kwithuba elithile lexesha.Umlinganiselo wedatha ochanekileyo sisiseko sokufunyanwa kwedatha.Iindlela zokulinganisa idatha ziqhagamshelwano kunye nokungaqhagamsheki, kwaye izinto zokubona ziyahluka.Kungakhathaliseki ukuba yeyiphi indlela kunye necandelo, isekelwe ekubeni ingachaphazeli imeko yento phantsi kovavanyo kunye nommandla wokulinganisa ukuqinisekisa ukuchaneka kwedatha.Ukufunyanwa kwedatha kuneempembelelo ezininzi, kubandakanywa ukufunyanwa kwezinto eziqhubekayo zomzimba ezichaseneyo.Kumzobo oncediswa yikhompyutha, imephu, kunye noyilo, inkqubo yokwenza imifanekiso yedijithali okanye imifanekiso ingaphinda ibhengezwe njengokufunyanwa kwedatha, apho ubungakanani bejometri (okanye ubungakanani bomzimba, obufana negreyscale) idatha iqokelelwa.

Injongo

Ukufunyanwa kwedatha kubhekiselele kwinkqubo yokuqokelela ngokuzenzekelayo ulwazi oluvela kwi-analog kunye neeyunithi zedijithali phantsi kovavanyo, njengeenzwa kunye nezinye izixhobo eziphantsi kovavanyo.Iinkqubo zokufumana idatha ziguquguqukayo, iinkqubo zokulinganisa ezichazwe ngumsebenzisi ezidibanisa i-hardware yokulinganisa ikhompyutha kunye neemveliso zesofthiwe.

Injongo yokufunyaniswa kwedatha kukulinganisa izinto ezenzeka emzimbeni ezifana nombane, umsinga, ubushushu, uxinzelelo, okanye isandi.Ukufunyanwa kwedatha esekwe kwiPC, kulinganiswa ngokudityaniswa kweemodyuli zehardware, isoftware yesicelo kunye nekhompyuter.Nangona iinkqubo zokufumana idatha zineenkcazo ezahlukeneyo ngokuxhomekeke kwiimfuno zezicelo ezahlukeneyo, inkqubo nganye iqokelela, ihlalutye kwaye ibonise ulwazi ngenjongo efanayo.Inkqubo yokufumana idatha idibanisa iimpawu, i-sensor, i-activators, i-signal conditioning, izixhobo zokufumana idatha, kunye nesofthiwe yesicelo.
