Ekukhiqizweni kwezimboni, amaseli umthwalo asetshenziswa kabanzi ukukala isisindo sezinto. Kodwa-ke, ukunemba kweseli lomthwalo kuyinto ebalulekile ekuhlolweni ukusebenza kwayo. Ukunemba kubhekiswa umehluko phakathi kwenani lokuphuma kwenzwa kanye nenani elizolinganiswa, futhi lisuselwa ezintweni ezifana nokwethenjwa kwenzwa nokuqina. Ngakho-ke, le ndatshana izodingida ukunemba kweseli lomthwalo kanye nesicelo sayo.
Kuyini ukunemba kweseli lomthwalo?
Ukunemba kwenzwa yenzwa kusho umehluko phakathi kwesiginali yayo yokuphuma kanye nenani elizolinganiswa, elivame ukuvezwa njengephesenti lenkomba yenkomba (iphutha lenkomba). Iphutha lenkomba yokunemba lihlukaniswe ngobuningi, amaphesenti kanye nephutha lenkomba yedijithali. Esitokisini somthwalo, iphutha elilinganiselayo (Iphutha eliqondile noma eliqondile) libhekisela kwiphutha elibangelwa yizinto ezifana nezinto zehardware, amapharamitha okukhiqiza, njll. Iphutha lamaphesenti (noma iphutha elihlobene) libhekisela kwiphutha lesilinganiso phakathi kokukhipha inzwa kanye nenani langempela; Iphutha ledijithali libhekisele kwiphutha elinembile elikhiqizwa ukubalwa kwedijithali (njenge-AD Converter).
Izici ezithonya ukunemba kwamaseli omthwalo
I-Mechanical Mistalignment: Ngesikhathi sokuzwakala kokusebenza ngokweqile, ukuphakamiseka kwemishini kuyimbangela evamile yokulahleka kokunemba kwenzwa. Izimbangela zokungalingani kwemishini zihlanganisa deformation ngokomzimba, ukugqwala kwesakhiwo, ukufakwa okungelona okujwayelekile, njll.
Amaphutha wokucubungula wesiginali: Amazinga omsindo wesiginali aphezulu kakhulu noma aphansi kakhulu angathinta umphumela wenzwa. Izimbangela zamaphutha anjalo zifaka isilinganiso esincane sedizayini, ukucubungula ukulahleka kwesifunda noma ikhwalithi empofu, njll.
Izici zezemvelo: Amaseli omthwalo asetshenziswa ezimweni ezihlukile zezemvelo, futhi izimo ezahlukahlukene zezemvelo zizothinta ukusebenza kweseli lomthwalo. Njengokushintsha kokushisa, impilo yokusebenza, sebenzisa imvelo, njll.
Ukuthuthukiswa kokunemba kweseli lomthwalo
Khetha inzwa efanele: Okokuqala kwakho konke, kufanele ukhethe imodeli yeseli efanele yomthwalo ngokuya ngesimo sangempela sohlelo ukuze uthole imiphumela yokulinganisa yesisindo esithe xaxa.
Khetha ngokucophelela imvelo yesicelo: lapho ufaka futhi usebenzisa iseli lomthwalo, ukunakwa kufanele kukhokhwe ethonyeni lezinto ezihlukile zezemvelo ezifana nokushisa okukhona kanye nokugqoka okwenziwe ngomshini ngokunemba kweseli lomthwalo. Ezinye izinkambiso kanye nobubanzi bokusebenzisa okunengqondo kufanele kulandelwe, njengokugwema indawo yokushisa ephezulu noma ephansi kakhulu.
Ukulinganisa insimbi: ukulinganisa okufanele kungakuthuthukisa ngempumelelo ukunemba kweseli lomthwalo. Ukulinganisa kuqinisekisa izici zokuphendula ze-Sensor, ukuzwela nokuqina. Ukulinganiswa kwelebhu ukuhlinzeka ngemiphumela efanele yokulinganisa ukunemba kweseli yomthwalo futhi kuthuthukise ukuthembeka kokulinganisa kweseli lomthwalo.
Ekuphetheni
Ukunemba kweseli lomthwalo kuyipharamitha ebalulekile ukukala ukunemba kwensiza yayo. Uchungechunge lwezinyathelo ezifana nokuthuthukisa ukuqina kwensimbi, ukunciphisa ukudlidliza kwemishini, kanye nokwenza ngcono izimo zemvelo kungathuthukisa ukunemba kweseli lomthwalo. Ukusebenza okufana nokulinganisa kungaqinisekisa nokuthi iseli lomthwalo lingaqhubeka nokusebenza ngokunembe.
