Nhanganyaya uye kupatsanurwa kwe encoders

An encodermudziyo unogadzira uye unoshandura chiratidzo (sekuyerera zvishoma) kana data kuita chiratidzo chechimiro chinogona kushandiswa kutaurirana, kutapurirana, uye kuchengetedza.Iyo encoder inoshandura angular displacement kana linear displacement kuita chiratidzo chemagetsi, yekutanga inonzi code disc, uye iyo yekupedzisira inonzi yardstick.Zvinoenderana neiyo nzira yekuverenga, iyo encoder inogona kukamurwa kuita mhando mbiri: yekubata mhando uye isiri-yekubata mhando;zvinoenderana nemusimboti wekushanda, iyo encoder inogona kukamurwa kuita mhando mbiri: incremental type uye absolute type.Iyo incremental encoder inoshandura kutamiswa kuita chiratidzo chemagetsi nguva nenguva, uye yozoshandura chiratidzo chemagetsi kuita pulse yekuverenga, uye inoshandisa huwandu hwemapulses kumiririra ukuru hwekutamisa.Imwe neimwe nzvimbo yeabsolute encoder inoenderana neimwe kodhi yedhijitari, saka chiratidzo chayo chinongoenderana nenzvimbo yekutanga uye yekupedzisira yechiyero, asi haina chekuita neyepakati maitiro ekuyera.

Kurongwa kwe encoders
Zvinoenderana nemusimboti wekuona, iyo encoder inogona kukamurwa kuita optical mhando, magineti mhando, inductive mhando uye capacitive mhando.Zvinoenderana neiyo calibration nzira uye chiratidzo chekubuda fomu, inogona kupatsanurwa mumhando nhatu: incremental type, absolute type uye hybrid type.
Kuwedzera encoder:

Kuwedzera encoderzvakananga inoshandisa musimboti wekushandurwa kwephotoelectric kuburitsa mapoka matatu esquare wave pulses A, B uye Z chikamu;mutsauko wechikamu pakati pemapoka maviri emapulses A uye B i90 madhigirii, kuitira kuti kutungamira kwekutenderera kugone kutariswa zviri nyore, nepo Phase Z iri imwe pulse per revolution, iyo inoshandiswa kune referensi point positioning.Mabhenefiti ayo ari nyore musimboti uye chimiro, avhareji yehupenyu hwemagetsi inogona kupfuura makumi ezviuru zvemaawa, yakasimba anti-kupindira kugona, kuvimbika kwepamusoro, uye yakakodzera kutapurirana kure-kure.
Absolute encoder:

Absolute encoder inzwa inoburitsa zvakananga nhamba.Pane yayo denderedzwa kodhi dhisiki, kune akati wandei concentric kodhi discs pamwe neiyo radial nzira.Miti yechikamu chekodhi yekodhi ine hukama huviri.Nhamba yemakodhi tracks pane kodhi dhisiki ndiyo nhamba yemanhamba eiyo binary nhamba.Kune rimwe divi rekodhi disc kune mwenje sosi, uye kune rumwe rutivi kune photosensitive chinhu chinoenderana nechero kodhi track.Kana iyo kodhi Kana dhisiki iri munzvimbo dzakasiyana, imwe neimwe photosensitive element inoshandura inoenderana nhanho chiratidzo zvichienderana nekuti yakavhenekerwa kana kwete, ichigadzira binary nhamba.Chimiro cheiyi encoder ndechekuti hapana counter inodiwa, uye yakamisikidzwa kodhi yedhijitari inoenderana nenzvimbo inogona kuverengerwa pane chero chinzvimbo cheinotenderera shaft.
Hybrid Absolute Encoder:

Hybrid absolute encoder, inoburitsa maviri maseti eruzivo, imwe seti yeruzivo inoshandiswa kuona iyo magineti pole chinzvimbo, ine mhedziso yeruzivo basa;imwe seti yakangofanana neruzivo rwekubuda kweiyo incremental encoder.
