Kuyini i-encoder?
Ngesikhathi sokusebenza kwemoto, ukuqapha ngesikhathi sangempela kwamapharamitha afana nogesi wamanje, isivinini sokujikeleza, kanye nendawo ehlobene yesiqondiso esijikelezayo seshafti ejikelezayo kunquma isimo se-injiniumzimba kanye nemishini edonswayo, kanye nokulawula ngesikhathi sangempela kwemoto kanye nezimo zokusebenza kwemishini, ngaleyo ndlela kufezwe i-servoing, ukulawulwa kwesivinini, kanye neminye imisebenzi eminingi ethile.
Lapha, ukusetshenziswa kwe-encoder njengento yokulinganisa engaphambili akugcini nje ngokwenza uhlelo lokulinganisa lube lula kakhulu, kodwa futhi kunembile, kuthembekile futhi kunamandla.
I-Encoder iyinzwa ejikelezayo eguqula indawo kanye nokuhanjiswa kwezingxenye ezijikelezayo zibe uchungechunge lwezibonakaliso ze-pulse zedijithali, eziqoqwa futhi zicutshungulwe uhlelo lokulawula ukuze zikhiphe uchungechunge lwemiyalo yokulungisa nokushintsha isimo sokusebenza kwemishini. Uma i-encoder ihlanganiswe ne-gear bar noma i-screw screw, ingasetshenziswa futhi ukukala ubuningi bendawo kanye nokuhanjiswa kwezingxenye ezihambayo eziqondile.
Ukuhlukaniswa okuyisisekelo kwe-encoder
I-Encoder iyinhlanganisela esondelene yemishini neye-elekthronikhi yamadivayisi okulinganisa ngokunemba, isignali noma idatha yokufaka ikhodi, ukuguqulwa, yokuxhumana, ukudluliselwa kanye nokugcinwa kwedatha yesignali.
I-encoder iyithuluzi lokulinganisa ngokunemba elihlanganisa izingxenye zemishini neze-elekthronikhi ukuze i-encode, iguqule, ixhumane, idlulise futhi igcine izimpawu nedatha. Ngokwezici ezahlukene, ukuhlukaniswa kwe-encoder kungokulandelayo: i-code disc kanye ne-code scale: ukufuduka okuqondile kube yizimpawu zikagesi ezibizwa ngokuthi i-code scale encoder, ukufuduka kwe-angular kube ukuxhumana kwe-code disc, - i-incremental encoder: ukunikeza isikhundla, i-angle kanye nenani lama-laps, njll., enanini lama-pulses ngokujika ngakunye ukuze kuchazwe izinga lokuhluka. -I-absolute encoder: Nikeza ulwazi olufana nesikhundla, i-angle kanye nenani lokujikeleza ekukhuphukeni kwe-angular, ukukhushulwa ngakunye kwe-angular kunikezwa ikhodi ehlukile.
-Ama-encoder aphelele e-hybrid: Ama-encoder aphelele e-hybrid akhipha amasethi amabili olwazi: isethi eyodwa yolwazi isetshenziselwa ukuthola indawo yezigxobo zikagesi, nomsebenzi wolwazi oluphelele; enye isethi ifana ncamashi nolwazi lokukhipha lwama-encoder angaphezulu.
Ama-encoder asetshenziswa kakhuluama-motor
Isifaki khodi esikhulayo
Ukusebenzisa ngqo isimiso sokuguqulwa kwe-photoelectric ekukhipheni amasethi amathathu ama-pulse amagagasi ayisikwele u-A, u-B no-Z. A, u-B amasethi amabili ama-pulse umehluko wesigaba sama-90o, kunganquma kalula isiqondiso sokujikeleza; isigaba se-Z sijika i-pulse, esetshenziselwa ukubeka iphuzu lokubhekisela. Izinzuzo: isimiso esilula sokwakhiwa, impilo ejwayelekile yomshini yamahora angamashumi ezinkulungwane noma ngaphezulu, ikhono eliqinile lokulwa nokuphazamiseka, ukuthembeka okuphezulu, okufanelekela ukudluliselwa ibanga elide. Okubi: ukungakwazi ukukhipha ulwazi oluphelele lwesikhundla sokujikeleza kwe-shaft.
Ama-encoder aphelele
Inzwa yedijithali ephuma ngqo, i-sensor eyindilinga yekhodi yediski eceleni kwesiqondiso se-radial seziteshi eziningi zekhodi ezigxilile, isiteshi ngasinye ngemikhakha ekhanyayo nengangenisi ukukhanya phakathi kokwakheka kwenani lemikhakha yeziteshi zekhodi eziseduze ubuhlobo obuphindwe kabili phakathi kwenani leziteshi zekhodi ku-disc yekhodi inani lezinombolo ezimbili enanini leziteshi zekhodi inani lama-bits e-disc yayo yekhodi, ku-disc yekhodi ohlangothini lomthombo wokukhanya, olunye uhlangothi lwesiteshi sekhodi oluhambisanayo kukhona isici esizwela ukukhanya; lapho i-disc yekhodi isendaweni ehlukile, isici esizwela ukukhanya ngokuvumelana nokukhanya noma cha siguqula isignali yezinga elihambisanayo ukuze sakhe inombolo ye-binary. Lapho i-disc yekhodi isesimweni esihlukile, isici ngasinye esizwela ukukhanya siguqula isignali yezinga elihambisanayo ngokusho kokukhanya noma cha ukuze sakhe inombolo ye-binary.
Lolu hlobo lwe-encoder lubonakala ngokuthi aludingi i-counter futhi ikhodi yedijithali eqondile ehambisana nendawo ingafundwa kunoma iyiphi indawo yeshaft ejikelezayo. Ngokusobala, uma isiteshi sekhodi sisikhulu, kulapho isinqumo siphezulu, ku-encoder ene-N-bit binary resolution, idiski yekhodi kumele ibe nesiteshi sebhakhodi se-N. Njengamanje, kunemikhiqizo ye-absolute encoder engu-16-bit.
Isimiso sokusebenza se-encoder
Ngesikhungo esinomgodi wepuleti lekhodi ye-photoelectric, elinendandatho edlula emigqeni emnyama, kunamadivayisi okudlulisa kanye nokwamukela nge-photoelectric okufanele uwafunde, ukuthola amasethi amane ezibonakaliso ze-sine wave ezihlanganiswe zibe yi-A, B, C, D, igagasi ngalinye le-sine elinomehluko wesigaba sama-degrees angu-90 (uma kuqhathaniswa negagasi elijikelezayo lama-degrees angu-360), ukuguqulwa kwesignali ye-C, D, okubekwe ngaphezulu kwesigaba se-A, B esinezigaba ezimbili, ezingathuthukiswa ukuze kuqiniswe isignali; kanti okunye ukujika ngakunye ukukhipha i-pulse yesigaba se-Z egameni lesikhundla se-zero.
Njengoba umehluko wesigaba A, B ezimbili zama-degrees angu-90, ungaqhathaniswa nesigaba A ngaphambili noma isigaba B ngaphambili, ukuze ubone ukujikeleza okuhle nokuhlehla kwe-encoder, ngokusebenzisa i-pulse engu-zero, ungathola isikhundla sereferensi esingu-zero se-encoder.
Izinto zediski ye-Encoder zinengilazi, insimbi, ipulasitiki, idiski yengilazi ibekwe engilazini emgqeni omncane kakhulu oqoshiwe, ukuzinza kwayo kokushisa kuhle, ukunemba okuphezulu, idiski yensimbi idlula ngqo futhi ingadluli umugqa oqoshiwe, ayibuthakathaka, kodwa ngenxa yobukhulu obuthile bensimbi, ukunemba kunqunyelwe, futhi ukuzinza kwayo kokushisa kuzoba kubi kakhulu kunokwengilazi yomyalelo omkhulu, idiski yepulasitiki iyonga, izindleko zayo ziphansi, kodwa ukunemba, ukuzinza kokushisa, isikhathi sokuphila kubi kakhulu. Amadiski epulasitiki ayonga, kodwa ukunemba, ukuzinza kokushisa, kanye nesikhathi sokuphila kubi kakhulu.
Isixazululo - isifaki khodi sokunikeza ukuthi zingaki imigqa edlulayo noma emnyama ngamadigri angu-360 okujikeleza sibizwa ngokuthi isixazululo, esaziwa nangokuthi isixazululo senkomba, noma esibizwa ngokuqondile ngokuthi imigqa emingaki, ngokuvamile imigqa emi-5 ~ 10,000 ngenkomba yokujikeleza.
Izimiso Zokulinganisa Isikhundla kanye Nokulawula Impendulo
Ama-encoder aphethe isikhundla esibaluleke kakhulu kuma-lift, amathuluzi omshini, ukucubungula izinto, izinhlelo zokuphendula kwezimoto kanye nemishini yokulinganisa nokulawula. Ama-encoder asebenzisa ama-optical gratings kanye nemithombo yokukhanya ye-infrared ukuguqula amasignali optical abe amasignali kagesi e-TTL (HTL) nge-receiver, ekhombisa ngokubonakalayo i-engeli yokujikeleza kanye nendawo yemoto ngokuhlaziya imvamisa yezinga le-TTL kanye nenani lamazinga aphezulu.
Njengoba i-engeli nendawo kungalinganiswa ngokunembile, kungenzeka ukwakha uhlelo lokulawula oluvaliwe olune-encoder kanye ne-inverter ukuze kwenziwe ukulawula kube ngokunembe kakhulu, yingakho ama-lift, amathuluzi omshini, njll. angasetshenziswa ngokunembe kangaka.
Isifinyezo
Ngamafuphi, siyaqonda ukuthi i-encoder ihlukaniswe ngezinhlobo ezimbili ezilandelanayo neziphelele ngokwesakhiwo, nazo ziyizinye izimpawu, njengezibonakaliso ze-optical, zibe izimpawu zikagesi ezingahlaziywa futhi zilawulwe. Futhi siphila endaweni yokuphakamisa evamile, amathuluzi omshini asekelwe nje ekulawulweni okunembile kwemoto, ngempendulo yokulawula kwesignali kagesi okuvaliwe, i-encoder ene-frequency converter nayo iyindaba yokufeza ukulawula okuqondile.
