Chii chinonzi encoder?
Munguva yekushanda kwemota, kutarisa maparamita panguva chaiyo senge magetsi, kumhanya kwekutenderera, uye nzvimbo yenzvimbo yedenderedzwa remugodhi unotenderera zvinosarudza mamiriro emota.motamuviri nemidziyo iri kudhonzwa, uye zvakare, kudzora mota nenguva chaiyo nemamiriro ekushanda kwemuchina, nokudaro zvichiita kuti injini ishande zvakanaka, kudzorwa kwekumhanya, uye mamwe mabasa akawanda chaiwo.
Pano, kushandiswa kwe encoder sechinhu chekuyera chepamberi hakungorerutsi chete hurongwa hwekuyera, asiwo kwakarurama, kwakavimbika uye kune simba.
Encoder i sensor inotenderera inoshandura nzvimbo uye kuchinjika kwezvikamu zvinotenderera kuita nhevedzano yezviratidzo zvedigital pulse, izvo zvinounganidzwa uye zvinogadziriswa ne control system kuti zvibudise nhevedzano yemirairo yekugadzirisa nekushandura mamiriro ekushanda kwemuchina. Kana encoder ikabatanidzwa ne gear bar kana screw screw, inogona zvakare kushandiswa kuyera huwandu hwenzvimbo uye kuchinjika kwezvikamu zvinofamba zvakatwasuka.
Kupatsanurana kwekutanga kwe encoder
Encoder musanganiswa wezvishandiso zvekuyera nemazvo, chiratidzo kana data rekunyora, kushandura, kutaurirana, kutumira uye kuchengetera data rechiratidzo.
Iyo encoder chishandiso chekuyera nemazvo chinosanganisa zvikamu zvemakanika nemagetsi kuti zvikwanise kunyora, kushandura, kutaurirana, kutumira uye kuchengeta zviratidzo nedata. Zvichienderana nehunhu hwakasiyana, kupatsanurwa kwe encoder ndekwekuti: kodhi dhisiki uye chiyero chekodhi: kuchinjika kwemutsetse muzviratidzo zvemagetsi kunonzi code scale encoder, kuchinjika kwe angular mukutaurirana kwekodhi dhisiki, - incremental encoder: kupa nzvimbo, kona uye nhamba yematanho, nezvimwewo, kuhuwandu hwema pulses pakuchinjana kutsanangura chiyero chezvakasiyana. -Absolute encoder: Ipa ruzivo rwakadai senzvimbo, kona uye nhamba yekuchinja mu angular increments, kuwedzera kwe angular kwega kwega kunopiwa kodhi yakasiyana.
-Hybrid absolute encoders: Hybrid absolute encoders inoburitsa ruzivo rweseti mbiri: rumwe ruzivo runoshandiswa kuona nzvimbo yemapore emagnetic, nebasa reruzivo rwese; rumwe ruzivo rwakafanana chaizvo neruzivo rwekubuda kweincremental encoders.
Ma encoders anoshandiswa zvakanyanya pamota
Incremental encoder
Kushandisa zvakananga musimboti wekushandurwa kwemagetsi emagetsi kuti abudise maseti matatu emafungu emafungu emativi mana A, B na Z. A, B maseti maviri emafungu akasiyana echikamu che90o, anogona kuona zviri nyore divi rekutenderera; Z-chikamu chega chega kutenderera kwemhepo, kunoshandiswa pakuisa nzvimbo yekutarisa. Zvakanakira: musimboti uri nyore wekuvaka, avhareji yehupenyu hwemachina hwemakumi ezviuru zvemaawa kana kupfuura, kugona kwakasimba kwekudzivirira kupindira, kuvimbika kwakanyanya, kwakakodzera kutumira kure kure. Zvakashata: kusakwanisa kuburitsa ruzivo rwenzvimbo yakakwana yekutenderera kwemugodhi.
Ma encoders akazara
Sensor yedhijitari inoburitsa zvakananga, sensor denderedzwa rekodhi dhisiki iri munzira ye radial yenzira dzakawanda dzekodhi dzakatenderedza, chiteshi chimwe nechimwe chine nzira yakajeka uye isingapindi chiedza pakati pehuwandu hwenzvimbo dziri pedyo dzekodhi chiteshi chiteshi hukama huviri pakati pehuwandu hwenzvimbo dzekodhi chiteshi pakodhi dhisiki ndere nhamba yemadijiti ebhinari panhamba yenzvimbo dzekodhi chiteshi ndere nhamba yemabhiti ekodhi dhisiki rayo, mukodhi dhisiki yedivi renzvimbo yechiedza, rimwe divi renzvimbo inoenderana nekodhi chiteshi chimwe nechimwe pane chinhu chinonzwa chiedza; kana kodhi dhisiki iri munzvimbo yakasiyana, chinhu chinonzwa chiedza zvinoenderana nechiedza kana kusashandura chiratidzo chemazinga anoenderana kuti chigadzire nhamba yebhinari. Kana kodhi dhisiki iri munzvimbo dzakasiyana, chinhu chimwe nechimwe chinonzwa chiedza chinoshandura chiratidzo chemazinga anoenderana zvichienderana nekuti chakavhenekerwa here kana kuti kwete kuti chigadzire nhamba yebhinari.
Rudzi urwu rwe encoder runoratidzwa nekuti harudi counter uye kodhi yedhijitari yakatarwa inoenderana nenzvimbo inogona kuverengwa chero panzvimbo ye rotating shaft. Zviri pachena kuti, kana kodhi yacho yakakura, resolution yacho inowedzera, kune encoder ine N-bit binary resolution, kodhi yacho inofanira kunge iine N barcode channel. Parizvino, kune zvigadzirwa zve 16-bit absolute encoder.
Nheyo yekushanda kweEncoder
Pakati penzvimbo ine shaft ye photoelectric code plate, ine rin'i inopinda nepakati pemitsetse yakasviba, pane michina ye photoelectric transmitter nereceiver yekuverenga, kuti uwane maseti mana e sine wave signals akabatanidzwa kuita A, B, C, D, sine wave yega yega ine phase difference ye 90 degrees (zvichienderana ne circumferential wave ye 360 degrees), C, D signal inversion, yakaiswa pamusoro pe A, B two-phase, iyo inogona kuwedzerwa kuti igare zvakanaka; uye imwe nguva yega yega inobuda Z-phase pulse panzvimbo ye zero position Reference position.
Sezvo musiyano weA, B nezvikamu zviviri uri madhigirii makumi mapfumbamwe, unogona kuenzaniswa nechikamu cheA chiri pamberi kana chikamu cheB chiri pamberi, kuti uone kutenderera kwakanaka uye kudzoreredzwa kwe encoder, kuburikidza ne zero pulse, unogona kuwana nzvimbo ye zero reference ye encoder.
Zvinhu zvedhisiki reEncoder zvine girazi, simbi, purasitiki, dhisiki regirazi rakaiswa mugirazi pamutsetse wakatetepa wakavezwa, kugadzikana kwaro kwekupisa kwakanaka, kunyatsojeka, dhisiki resimbi zvakananga kuti ripfuure uye risapfuure mutsetse wakavezwa, harisi kusimba, asi nekuda kwehukobvu hwakati hwesimbi, kunyatsojeka kwakaganhurirwa, uye kugadzikana kwaro kwekupisa kuchava kwakaipa kupfuura kwegirazi rakakura, dhisiki repurasitiki rinodhura, mutengo waro wakaderera, asi kururama, kugadzikana kwekupisa, uye hupenyu hwenguva refu hwakaipa. Madhisiki epurasitiki anodhura, asi kururama, kugadzikana kwekupisa, uye hupenyu hwenguva refu hwakaipa.
Resolution - encoder yekupa kuti mitsetse mingani inodarika kana yerima pa360 degrees yekutenderera inonzi resolution, inozivikanwawo se resolution ye index, kana kuti inonzi zvakananga kuti mitsetse mingani, kazhinji mitsetse 5 ~ 10,000 pa index ye revolution.
Kuyera Nzvimbo uye Nheyo Dzekudzora Mhinduro
Ma encoders ane chinzvimbo chakakosha zvikuru muma lifts, machine tools, material processing, motor feedback systems uye measurement and control equipment. Ma encoders anoshandisa optical gratings uye infrared light sources kushandura optical signals kuita TTL (HTL) electrical signals kuburikidza ne receiver, iyo inoratidza rotational angle nenzvimbo yemota nekuongorora frequency yeTTL level uye huwandu hwemazinga akakwira.
Sezvo kona nenzvimbo zvichigona kuyerwa nemazvo, zvinokwanisika kugadzira sisitimu yekudzora yakavharwa ine encoder neinverter kuti control ive yakanyatsojeka, ndosaka ma lift, maturusi emuchina, nezvimwewo zvichigona kushandiswa nemazvo.
Pfupiso
Muchidimbu, tinonzwisisa kuti encoder yakakamurwa kuita mhando mbiri dzinotevedzana uye dzakakwana zvichienderana nechimiro, idzowo dzimwe zviratidzo, dzakadai semasaini ekuona, kuita zviratidzo zvemagetsi zvinogona kuongororwa nekudzorwa. Uye isu tinogara mukusimudza kwakajairika, zvishandiso zvemuchina zvinongoenderana nekutonga kwakarurama kwemota, kuburikidza nemhinduro yechiratidzo chemagetsi chinodzorwa-chinotenderera, encoder ine frequency converter inyaya yechokwadi yekuwana kutonga kwakarurama.
