Kuyambitsa ndi kugawa kwa ma encoder

An encoderndi chipangizo chomwe chimaphatikiza ndikusintha chizindikiro (monga kutsetsereka pang'ono) kapena data kukhala mawonekedwe omwe angagwiritsidwe ntchito polumikizana, kutumiza, ndi kusunga.Encoder imatembenuza kusamuka kwa angular kapena kusamuka kwa mzere kukhala chizindikiro chamagetsi, choyambiriracho chimatchedwa code disc, ndipo chomalizacho chimatchedwa yardstick.Malinga ndi njira yowerengera, encoder imatha kugawidwa m'mitundu iwiri: mtundu wolumikizana ndi mtundu wosalumikizana;molingana ndi mfundo yogwirira ntchito, encoder imatha kugawidwa m'mitundu iwiri: mtundu wowonjezera ndi mtundu wathunthu.Encoder yowonjezereka imasintha kusunthako kukhala siginecha yamagetsi yanthawi ndi nthawi, kenako ndikusintha chizindikiro chamagetsi kukhala chowerengera, ndikugwiritsa ntchito kuchuluka kwa ma pulses kuyimira kukula kwa kusamukako.Malo aliwonse a encoder mtheradi amafanana ndi code ya digito, kotero chisonyezero chake chimangogwirizana ndi malo oyambira ndi otsiriza a muyeso, koma alibe chochita ndi ndondomeko yapakati ya muyeso.

Gulu la ma encoder
Malinga ndi mfundo yodziwikiratu, encoder imatha kugawidwa mumtundu wa kuwala, mtundu wa maginito, mtundu wa inductive ndi mtundu wa capacitive.Malingana ndi njira yake yowonetsera ndi mawonekedwe a chizindikiro, akhoza kugawidwa m'magulu atatu: mtundu wowonjezera, mtundu wamtundu ndi mtundu wosakanizidwa.
Encoder yowonjezera:

Encoder yowonjezeramwachindunji amagwiritsa ntchito mfundo photoelectric kutembenuka linanena bungwe magulu atatu lalikulu mafunde pulses A, B ndi Z gawo;kusiyana kwa magawo pakati pa magulu awiri a pulses A ndi B ndi madigiri a 90, kotero kuti kayendetsedwe ka kasinthasintha kakhoza kuweruzidwa mosavuta, pamene Phase Z ndi phokoso limodzi pa kusintha, komwe kumagwiritsidwa ntchito polemba malo.Ubwino wake ndi mfundo yosavuta komanso kapangidwe kake, pafupifupi moyo wamakina amatha kukhala opitilira makumi masauzande a maola, mphamvu zotsutsana ndi kusokoneza, kudalirika kwakukulu, komanso koyenera kufalitsa mtunda wautali.
Encoder mtheradi:

Absolute encoder ndi sensor yomwe imatulutsa manambala mwachindunji.Pa diski yake yozungulira, pali ma disc angapo a concentric code motsatira njira ya radial.Mitengo yamagulu amtundu wa code ili ndi ubale wapawiri.Chiwerengero cha ma code pa code disc ndi chiwerengero cha manambala a nambala yake ya binary.Kumbali imodzi ya code chimbale ndi kuwala gwero, ndi mbali ina pali photosensitive chinthu lolingana aliyense kachidindo njanji.Pamene code pamene diski ili m'malo osiyanasiyana, chinthu chilichonse chojambula zithunzi chimasintha chizindikiro chofananira molingana ndi chowunikira kapena ayi, ndikupanga nambala ya binary.Mbali ya encoder iyi ndikuti palibe chowerengera chomwe chikufunika, ndipo nambala yadijito yokhazikika yogwirizana ndi malowa imatha kuwerengedwa pamalo aliwonse a shaft yozungulira.
Hybrid Absolute Encoder:

Hybrid absolute encoder, imatulutsa zidziwitso ziwiri, chidziwitso chimodzi chimagwiritsidwa ntchito kuzindikira malo a maginito, okhala ndi chidziwitso chokwanira;seti inayo ndi yofanana ndendende ndi chidziwitso chotulutsa cha encoder yowonjezereka.
