Ukwethulwa nokuhlelwa kwezifaki khodi

An isifaki khodiiyidivayisi ehlanganisa futhi eguqule isignali (efana nokusakaza kancane) noma idatha ibe ifomu lesignali engasetshenziselwa ukuxhumana, ukudlulisa, nokugcina.Isifaki khodi siguqula ukugudluka kwe-angular noma ukugudluzwa ngomugqa kube isignali kagesi, eyokuqala ibizwa ngokuthi i-code disc, kanti lena yakamuva ibizwa ngokuthi i-yardstick.Ngokwendlela yokufunda, isishumeki singahlukaniswa sibe izinhlobo ezimbili: uhlobo lokuxhumana kanye nohlobo olungathintwa;ngokuya ngesimiso sokusebenza, isishumeki singahlukaniswa sibe izinhlobo ezimbili: uhlobo olukhulayo kanye nohlobo oluphelele.Isifaki khodi esikhulayo siguqulela ukugudluzwa kube isignali kagesi yezikhathi ezithile, bese siguqulela isignali kagesi ibe ishayela lokubala, futhi sisebenzisa inombolo yama-pulses ukumela ubukhulu bokususwa.Indawo ngayinye yesifaki khodi esiphelele ihambisana nekhodi ethile yedijithali, ngakho inkomba yayo ihlobene kuphela nendawo yokuqala nesiphetho yesilinganiso, kodwa ayihlanganise lutho nenqubo emaphakathi yesilinganiso.

Ukuhlelwa kwezifaki khodi
Ngokomgomo wokutholwa, isishumeki sekhodi singahlukaniswa sibe uhlobo olubonayo, uhlobo lukazibuthe, uhlobo lwe-inductive kanye nohlobo lwe-capacitive.Ngokwendlela yayo yokulinganisa kanye nefomu lokukhipha isignali, ingahlukaniswa ngezinhlobo ezintathu: uhlobo olukhulayo, uhlobo oluphelele kanye nohlobo oluxubile.
Isifaki khodi esikhulayo:

Isifaki khodi esikhulayoisebenzisa ngokuqondile isimiso sokuguqulwa kwe-photoelectric ukuze ikhiphe amaqembu amathathu ama-square wave pulses A, B kanye no-Z isigaba;umehluko wesigaba phakathi kwamaqembu amabili ama-pulses A no-B angama-degree angu-90, ukuze isiqondiso sokuzungeza sahlulelwe kalula, kuyilapho iSigaba Z siwukushaya okukodwa kokuphenduka ngakunye, okusetshenziselwa ukubeka iphuzu lenkomba.Izinzuzo zayo ziyisimiso esilula nesakhiwo, isilinganiso sempilo yemishini singaba ngaphezu kwamashumi ezinkulungwane zamahora, ikhono eliqinile lokulwa nokuphazamiseka, ukwethembeka okuphezulu, futhi ifanele ukudluliswa kwebanga elide.
Isifaki khodi esiphelele:

I-Absolute encoder iyinzwa ekhipha izinombolo ngokuqondile.Ku-disc yayo yekhodi eyindilinga, kunama-disc ekhodi e-concentric amaningana eduze kwesiqondiso se-radial.Izihlahla zomkhakha wethrekhi yekhodi zinobudlelwano obukabili.Inombolo yamathrekhi ekhodi kudiski yekhodi inombolo yamadijithi enamba yayo kanambambili.Ngakolunye uhlangothi lwekhodi yekhodi kuwumthombo wokukhanya, futhi ngakolunye uhlangothi kunesici se-photosensitive esihambisana nethrekhi ngayinye yekhodi.Uma ikhodi Uma idiski isendaweni ehlukene, isici ngasinye se-photosensitive siguqula isignali yeleveli ehambisanayo ngokuya ngokuthi ikhanyisiwe noma cha, kwakheka inombolo kanambambili.Isici salesi sishumeki sekhodi ukuthi asikho isibali esidingekayo, futhi ikhodi yedijithali egxilile ehambisana nendawo ingafundwa kunoma iyiphi indawo ye-shaft ejikelezayo.
I-Hybrid Absolute Encoder:

I-Hybrid absolute encoder, ikhipha amasethi amabili olwazi, isethi eyodwa yolwazi isetshenziselwa ukuthola indawo yesigxobo kazibuthe, nomsebenzi wolwazi oluphelele;enye isethi ifana ncamashi nolwazi oluphumayo lwesishumeki esikhulayo.
