Kusiyana pakati pa ma encoder owonjezera ndi absolute encoder.

Indondomeko yowonjezera encoder

Ma gratings owonjezera amakhala ndi mizere ya periodic.Kuwerenga kwa chidziwitso cha malo kumafuna malo ofotokozera, ndipo malo a nsanja yam'manja amawerengedwa poyerekezera ndi malo ofotokozera.

Popeza malo ofotokozera ayenera kugwiritsidwa ntchito kuti adziwe mtengo wa malo, mfundo imodzi kapena zingapo zimalembedwanso pa sikelo yowonjezereka.Mtengo wa malo otsimikiziridwa ndi malo owonetsera ukhoza kukhala wolondola ku nthawi imodzi ya chizindikiro, ndiko kuti, kuthetsa.Nthawi zambiri, sikelo yamtunduwu imagwiritsidwa ntchito chifukwa ndiyotsika mtengo kuposa sikelo yokwanira.

Komabe, kutengera liwiro komanso kulondola, kuthamanga kwambiri kwa sikani ya grating yowonjezereka kumadalira ma frequency olowera (MHz) amagetsi omwe amalandira komanso kusamvana kofunikira.Komabe, popeza kuchuluka kwanthawi zonse kwamagetsi omwe amalandila kumakhazikika, kukulitsa chigamulocho kumabweretsa kuchepa kofananira ndi liwiro lalikulu komanso mosemphanitsa.

Mtheradi encoder dongosolo

Mtheradi grating, mtheradi malo zambiri amachokera grating code chimbale, yomwe imakhala ndi mndandanda wa zizindikiro mtheradi zolembedwa pa wolamulira.Chifukwa chake, encoder ikayatsidwa, mtengo wamalo ukhoza kupezedwa nthawi yomweyo, ndipo ukhoza kuwerengedwa ndi dera lotsatira lazizindikiro nthawi iliyonse, osasuntha axis, ndikuchita ntchito yobwereza yobwereza.

Chifukwa kukonza nyumba kumatenga nthawi, kuwongolera kunyumba kumatha kukhala kovuta komanso kuwononga nthawi ngati makinawo ali ndi nkhwangwa zingapo.Pankhaniyi, ndi bwino kugwiritsa ntchito sikelo mtheradi.

Komanso, encoder mtheradi sichidzakhudzidwa ndi kuchuluka kwafupipafupi kwa chipangizo chamagetsi, kuonetsetsa kuti ntchito yothamanga kwambiri komanso yopambana.Izi ndichifukwa choti malowa amatsimikiziridwa pakufunika komanso kugwiritsa ntchito kulumikizana kosalekeza.Kugwiritsa ntchito kwambiri ma encoder absolute ndi makina oyika pamakina apamwamba aukadaulo (SMT), pomwe nthawi yomweyo kuwongolera liwiro komanso kulondola ndi cholinga chosatha.
