Musiyano pakati pekuwedzera uye absolute encoder masisitimu.

Incremental encoder system

Kuwedzera magireti kunosanganisira periodic mitsara.Kuverenga kweruzivo rwechinzvimbo kunoda nzvimbo yereferenzi, uye chinzvimbo chepuratifomu inoverengerwa nekuenzanisa nenzvimbo yereferensi.

Sezvo mhedziso yereferensi ichifanira kushandiswa kuona kukosha kwechinzvimbo, imwe kana anopfuura mareferenzi mapoinzi akatemerwawo pachiyero chekuwedzera chegirati.Iko kukosha kwechinzvimbo kunotarwa nereferenzi point inogona kuve yakarurama kune imwe chiratidzo nguva, ndiko kuti, kugadzirisa.Kazhinji, rudzi urwu rwechiyero runoshandiswa nekuti rwakachipa pane chikero chakakwana.

Nekudaro, maererano nekumhanya uye nekurongeka, iyo yakanyanya kutarisisa kumhanya kweiyo inowedzera grating zvinoenderana neiyo yakanyanya kupinza frequency (MHz) yemagetsi ekugamuchira uye inodiwa kugadziriswa.Nekudaro, sezvo iyo yakanyanya kuwanda kweiyo inogashira yemagetsi yakagadziriswa, kuwedzera kugadzirisa kunozokonzera kuderera kunowirirana mukumhanya kwakanyanya uye zvinopesana.

Absolute encoder system

Absolute grating, iyo mhedziso yenzvimbo ruzivo runobva kune grating kodhi disc, iyo ine nhevedzano yemakodhi akazara akanyorwa pamutongi.Naizvozvo, kana iyo encoder ikabatidzwa, kukosha kwechinzvimbo kunogona kuwanikwa nekukasira, uye inogona kuverengerwa neinozotevera chiratidzo chedunhu chero nguva, pasina kufambisa axis, uye kuita referensi poindi yekudzoka oparesheni.

Nekuti kumba kunotora nguva, kutenderera kwemba kunogona kunetsa uye kutora nguva kana muchina wacho uine akawanda mbezo.Muchiitiko ichi, zvinobatsira kushandisa chiyero chakakwana.

Zvakare, iyo encoder yakakwana haizokanganiswe neiyo yakanyanya kupinza frequency yemagetsi mudziyo, kuve nechokwadi chepamusoro-kumhanya uye yakakwirira-resolution kushanda.Izvi zvinodaro nekuti iyo nzvimbo inotemerwa pakudiwa uye kushandisa serial kutaurirana.Iyo inonyanya kushandiswa kushandiswa kweabsolute encoder ndiyo yekuisa muchina mune yepamusoro Mount tekinoroji (SMT) indasitiri, apo panguva imwe cheteyo kuvandudza kukurumidza kwekuisa uye kurongeka ndicho chinangwa chisingaperi.
