Iyo photoelectric encoder i sensor inoshandura iyo mechanic geometric displacement pane inobuda shaft kuita pulses kana dhijitari huwandu kuburikidza nephotoelectric shanduko, uye ndiyo inonyanya kushandiswa sensor. Iyo general photoelectric encoder inonyanya kuumbwa negiredhi disc uye photoelectric yekuona mudziyo. Mune servo system, sezvo iyo photoelectric encoder iri coaxial nemota, kana mota ichitenderera, grating disk inotenderera nekumhanya kwakafanana nemota. Mudziyo wekuona unogadzirwa nechiedza-emitting diodes nezvimwe zvinhu zvemagetsi zvinoona nekuburitsa masaini akati wandei. Iyo yazvino mota kumhanya inogona kuratidzwa nekuverenga huwandu hweanobuda mapurusi eiyo photoelectric encoder pasekondi. Pamusoro pazvo, kuti uone kwainotenderera, encoder inokwanisawo kupa maviri-channel optical code output ine phase difference ye90℃, uye kuona kutenderera kwemotor zvichienderana nekushanduka kwestate of the dual{8}}channel optical code. Zvinoenderana nemusimboti wekuona, encoders inogona kukamurwa kuita optical, magineti, inductive uye capacitive. Zvinoenderana nechiyero chayo nzira uye chiratidzo chekubuda fomu, inogona kupatsanurwa mumhando nhatu: inowedzera, yakakwana uye yakasanganiswa.
Kuwedzera encoder
Incremental encoders anoshandisa zvakananga musimboti wephotoelectric conversion kuburitsa matatu matatu esquare wave pulses A, B uye Z phase; A uye B maviri seti yemapulses ane mutsauko wechikamu che90 degree, kuitira kuti kutungamira kwekutenderera kugone kutariswa zviri nyore, uye chikamu cheZ chiri parevolution Imwe pulse inoshandiswa pakunongedza poindi yekumisikidza. Zvayakanakira chimiro chakareruka, avhareji yehupenyu hwemuchina inopfuura makumi ezviuru zvemaawa, yakasimba yekurwisa-kugona kukanganisa, kuvimbika kwepamusoro, uye yakakodzera kutapura{3}kurebesa. Izvo zvisingabatsiri ndezvokuti iyo yakakwana nzvimbo ruzivo rwekutenderera kwe shaft haigone kubuda.
Absolute encoder
Iyo yakakwana encoder inzwa inoburitsa zvakananga huwandu hwedhijitari. Kune akati wandei concentric code tracks pamwe neiyo radial kutungamira pane yayo denderedzwa kodhi disc. Tureyi yega yega inoumbwa ne{{2}transmissive uye opaque sectors} Iwo mafeni epadhuze kodhi chiteshi Huwandu hwenzvimbo hukama huviri. Huwandu hwemakodhi chiteshi pavhiri rekodhi ndiyo nhamba yemabhinari manhamba. Kune rimwe divi revhiri rekodhi ndiko kune mwenje sosi, uye rimwe divi rine photosensitive element inoenderana neimwe kodhi chiteshi; apo vhiri rekodhi riri munzvimbo dzakasiyana-siyana Kana, chimwe nechimwe chephotosensitive chinoshandura chinoenderana nechiyero chezinga zvichienderana nokuti inogamuchira chiedza kana kwete, uye inoumba nhamba yebhinari. Hunhu hwemhando iyi ye encoder ndeyekuti haidi counter, uye yakamisikidzwa kodhi yedhijitari inoenderana nechinzvimbo inogona kuverengerwa pane chero chinzvimbo cheshaft. Zviripachena, iyo yakawanda kodhi chiteshi, iyo yakakwirira resolution. Kune encoder ine N{{9}bit binary resolution, code disk inofanira kuva neN code channels. Patova ne21-bit absolute encoder zvigadzirwa muChina.
Mhedziso encoder inoshandisa yakasikwa bhinari kana cyclic binary (Grey kodhi) nzira yekushandura photoelectric. Musiyano uripo pakati peabsolute encoder uye incremental encoder ndiyo yakajeka uye opaque mutsara patani pane disc. Mhedziso encoder inogona kuve nemakodhi akati wandei, uye iyo mhedziso chinzvimbo inogona kuwonekwa zvinoenderana nekodhi pane yekuverenga kodhi disc. Dhizaini yekukodha inogona kutora bhinari kodhi, cyclic kodhi, maviri anozadzisa kodhi, nezvimwe.
Iyo yakakwana kukosha kweiyo angle coordinate inogona kuverengwa zvakananga; hapana kukanganisa kwakaunganidzwa; ruzivo rwechinzvimbo haruzorasikirwe mushure mekunge simba ragurwa. Zvisinei, kugadziriswa kunotarirwa nehuwandu hwebhiti mubhinari system, izvo zvinoreva kuti kurongeka kunoenderana nenhamba yebhiti.
Hybrid absolute encoder
Hybrid absolute encoder, inoburitsa maviri maseti eruzivo: imwe seti yeruzivo inoshandiswa kuona iyo magineti pole chinzvimbo, ine yakazara ruzivo basa; imwe seti yakangofanana neruzivo rwekubuda kweiyo incremental encoder.
