Yini i-encoder?
Ngesikhathi sokusebenza kwemoto, ukuqapha kwesikhathi sangempela kwamapharamitha njengamanje, isivinini sokuzungeza, kanye nesimo esihlobene sokujikeleza kwe-shaft ejikelezayo kunquma isimoimotoumzimba nezinto zokusebenza ezidonswayo, futhi ngaphezu kwalokho, ukulawula kwesikhathi sangempela kwenjini nezimo zokusebenza zemishini, ngaleyo ndlela kuqashelwe ukuseviswa, ukulawulwa kwesivinini, kanye neminye imisebenzi eminingi ethile.
Lapha, ukusetshenziswa kwesishumeki sekhodi njengengxenye yokulinganisa yangaphambili akwenzi nje kuphela isistimu yokulinganisa ibe lula, kodwa futhi kunembile, ethembekile futhi enamandla.
I-Encoder iyinzwa ejikelezayo eguqula indawo kanye nokugudluzwa kwezingxenye ezijikelezayo zibe uchungechunge lwamasiginali we-digital pulse, aqoqwa futhi acutshungulwe uhlelo lokulawula ukuze kukhishwe uchungechunge lwemiyalo ukuze kulungiswe futhi kushintshwe isimo sokusebenza sesisetshenziswa. Uma isifaki khodi sihlanganiswe nebha yegiya noma isikulufu sesikulufu, singasetshenziswa futhi ukukala inani elibonakalayo lendawo kanye nokugudluzwa kwezingxenye ezinyakazayo.
Ukuhlukaniswa okuyisisekelo kwesifaki khodi
I-encoder iyinhlanganisela esondelene yomshini neye-elekthronikhi yamadivayisi wokulinganisa ukunemba, isignali noma idatha yokurekhoda, ukuguqulwa, ukuxhumana, ukudlulisa nokugcinwa kwedatha yesignali.
Isishumeki idivayisi yokulinganisa ukunemba ehlanganisa izingxenye zemishini ne-elekthronikhi ukuze ihlanganise, iguqule, ixhumane, idlulise futhi igcine amasiginali nedatha. Ngokwezici ezihlukene, ukuhlukaniswa kwe-encoder kungokulandelayo: i-code disc nesikali sekhodi: ukugudluzwa komugqa kumasiginali kagesi okubizwa nge-code scale encoder, ukufuduka kwe-angular ku-telecommunications ye-code disc, - isishumeki sekhodi esikhuphukayo: ukunikeza isikhundla, i-engeli kanye nenombolo yama-laps, njll. -Absolute encoder: Nikeza ulwazi olufana nendawo, i-engeli kanye nenani lama-revolutions ekunyusweni kwe-angular, ukukhuphuka kwe-angular ngakunye kunikezwa ikhodi eyingqayizivele.
-Izishumeki eziphelele zeHybrid: Izishumeki eziphelele zeHybrid zikhipha amasethi amabili olwazi: isethi eyodwa yolwazi isetshenziselwa ukuthola indawo yezigxobo kazibuthe, nomsebenzi wolwazi oluphelele; enye isethi ifana ncamashi nolwazi oluphumayo lwezishumeki ezikhulayo.
Izifaki khodi ezisetshenziswa kakhuluizinjini
Isifaki khodi esikhulayo
Ngokuqondile usebenzisa umgomo wokuguqulwa kwe-photoelectric ukuze ukhiphe amasethi amathathu ama-square wave pulses A, B no-Z. A, B amasethi amabili wesigaba se-pulses umehluko we-90o, angakwazi ukucacisa kalula isiqondiso sokujikeleza; I-Z-isigaba njalo i-pulse, esetshenziselwa ukubeka indawo yereferensi. Izinzuzo: isimiso esilula sokwakha, isilinganiso sempilo yemishini yamashumi ezinkulungwane zamahora noma ngaphezulu, ikhono eliqinile lokulwa nokuphazamiseka, ukwethembeka okuphezulu, kufanelekile ukudluliswa kwebanga elide. Ukungalungi: ayikwazi ukukhipha ulwazi oluphelele lwendawo yokujikeleza kwe-shaft.
Izifaki khodi eziphelele
Inzwa yedijithali ephumayo eqondile, i-sensor eyindilinga yekhodi disc eduze kokuqondisa kwe-radial yenombolo yamashaneli ekhodi agxilile, isiteshi ngasinye yimikhakha ekhanyayo-esobala kanye ne-light-impermeable phakathi kokubunjwa kwenombolo yemikhakha eseduze yekhodi yekhodi ubuhlobo obuphindwe kabili phakathi kwenani lamashaneli ekhodi kwi-code disc inombolo yamadijithi kanambambili enanini lamashaneli ekhodi inombolo ye-disc ohlangothini lwekhodi yokukhanya, enye ingxenye yekhodi yomthombo wayo. okuhambisana nesiteshi ngasinye sekhodi kukhona into ezwela ukukhanya; lapho i-code disc isendaweni ehlukile, into ezwela ukukhanya ngokuya ngokukhanya noma ingaguquli isignali yezinga ehambisanayo ukuze yakhe inombolo kanambambili. Uma idiski yekhodi isendaweni ehlukene, i-elementi ngayinye ye-photosensitive iguqula isignali yeleveli ehambisanayo ngokuya ngokuthi iyakhanyiswa yini noma cha ukuze yakhe inombolo kanambambili.
Lolu hlobo lwesifaki khodi lubonakala ngeqiniso lokuthi aludingi ikhawunta futhi ikhodi yedijithali egxilile ehambisana nendawo ingafundwa kunoma iyiphi indawo ye-shaft ejikelezayo. Ngokusobala, uma isiteshi sekhodi sikhula, ukulungiswa kuphezulu, kusifaki khodi esinokulungiswa kanambambili kwe-N-bit, idiski yekhodi kufanele ibe neshaneli yebhakhodi engu-N. Njengamanje, kunemikhiqizo yesishumeki se-16-bit absolute.
Umgomo wokusebenza kwesifaki khodi
Ngaphakathi nendawo ene-shaft yepuleti lekhodi ye-photoelectric, enendandatho emigqeni emnyama, kukhona i-photoelectric transmitter ne-receiver device okufanele ifundwe, ukuze kutholwe amasethi amane amasignali we-sine wave ahlanganiswe abe yi-A, B, C, D, igagasi ngalinye le-sine elinomehluko wesigaba wama-degrees angu-90 (okuhlobene negagasi elijikelezayo le-360 degree inversion, i-B, i-D, i-A, i-D, i-B, i-A, i-D, i-A, i-D, ingathuthukiswa ukuze izinze isignali; futhi okunye ukujika ngakunye ukuze kukhishwe ukushaya kwesigaba esingu-Z esikhundleni sendawo eyiziro yereferensi.
Njengo-A, B umehluko wezigaba ezimbili wamadigri angu-90, ungaqhathaniswa nesigaba esingu-A ngaphambili noma isigaba B ngaphambili, ukuze ubone isifaki khodi esizuzisayo esihle nesihlehlayo, nge-pulse enguziro, ungathola indawo yereferensi yesifaki khodi enguziro.
I-encoder disc impahla inengilazi, insimbi, ipulasitiki, idiski yengilazi ifakwe engilazini emugqeni omncane kakhulu oqoshiwe, ukuzinza kwayo okushisayo kuhle, ukunemba okuphezulu, i-disc yensimbi ngokuqondile ukuze idlule futhi ingadluli umugqa oqoshiwe, hhayi obuthakathaka, kodwa ngenxa yobukhulu obuthile bensimbi, ukunemba kulinganiselwe, futhi ukuzinza kwayo okushisayo kuyoba kubi kakhulu kunalokho kwengilazi yengilazi ye-oda eliphansi, kodwa i-plastic discnitude iphansi, izindleko ze-disc ziphansi, i-plastic disc iphansi ukunemba, ukuzinza okushisayo, isikhathi sokuphila sibi kakhulu. Amadiski epulasitiki ayonga, kodwa ukunemba, ukuzinza kokushisa, nesikhathi sokuphila kubi kakhulu.
Ukulungiswa - isifaki khodi sokunikeza ukuthi bangaki imigqa edlulayo noma emnyama ngamadigri angu-360 wokuzungezisa kubizwa ngokuthi ukulungiswa, okubuye kwaziwe ngokuthi ukulungiswa kwenkomba, noma okubizwa ngokuqondile ngokuthi mingaki imigqa, ngokuvamile imigqa engu-5 ~ 10,000 ngenkomba ye-revolution ngayinye.
Ukukalwa Kwesikhundla kanye Nezimiso Zokulawula Impendulo
Izifaki khodi zithatha isikhundla esibaluleke kakhulu ekuphakameni, amathuluzi omshini, ekucutshungulweni kwezinto ezibonakalayo, amasistimu wempendulo yezimoto kanye nemishini yokulinganisa nokulawula. Izifaki khodi zisebenzisa igridi yokubona nemithombo yokukhanya kwe-infrared ukuguqula amasiginali okukhanya abe amasiginali kagesi we-TTL (HTL) ngesitholi, esibonisa ngokubonakalayo i-engeli yokujikeleza nendawo yemoto ngokuhlaziya imvamisa yeleveli ye-TTL kanye nenani lamazinga aphezulu.
Njengoba i-engeli nendawo kungalinganiswa ngokunembile, kungenzeka ukwenza isistimu yokulawula iluphu evaliwe ngesishumeki ne-inverter ukwenza isilawuli sicace nakakhulu, yingakho ama-lift, amathuluzi omshini, njll. angasetshenziswa ngokunembe kangaka.
Isifinyezo
Kafushane, siyaqonda ukuthi isishumeki sehlukaniswe izinhlobo ezimbili ezikhuphukayo neziphelele ngokuya ngesakhiwo, zingamanye amasiginali, njengamasiginali obonakalayo, kumasiginali kagesi angahlaziywa futhi alawulwe. Futhi siphila ekuphakameni okuvamile, amathuluzi omshini asekelwe nje ekulawuleni okunembayo kwenjini, ngempendulo yesilawuli sesignali kagesi esivaliwe, isishumeki esinesiguquli semvamisa nakho kuyindaba yokufinyelela ukulawula okunembayo.
