1, Kuyini i-encoder
Ngesikhathi sokusebenza kwe-Injini yegiya le-Worm N20 DC, amapharamitha afana namanje, isivinini kanye nendawo ehlobene yesiqondiso esijikelezayo seshaft ejikelezayo aqashwa ngesikhathi sangempela ukuze kutholakale isimo somzimba wemoto kanye nemishini edonswayo, futhi ngaphezu kwalokho ukulawula izimo zokusebenza zemoto kanye nemishini ngesikhathi sangempela, ngaleyo ndlela kufezwe imisebenzi eminingi ethile efana nokulawulwa kwe-servo kanye nesivinini. Lapha, ukusetshenziswa kwe-encoder njengento yokulinganisa engaphambili akugcini nje ngokwenza kube lula kakhulu uhlelo lokulinganisa, kodwa futhi kunembile, kuthembekile futhi kunamandla. I-encoder iyinzwa ejikelezayo eguqula inani elibonakalayo lesikhundla kanye nokufuduka kwezingxenye ezijikelezayo zibe uchungechunge lwezibonakaliso ze-pulse zedijithali, eziqoqwa futhi zicutshungulwe uhlelo lokulawula ukuze kukhishwe uchungechunge lwemiyalo yokulungisa nokushintsha isimo sokusebenza semishini. Uma i-encoder ihlanganiswe ne-gear bar noma i-screw screw, ingasetshenziswa futhi ukukala isikhundla kanye nokufuduka kwezingxenye ezihambayo eziqondile.
2, ukuhlukaniswa kwe-encoder
Ukuhlukaniswa okuyisisekelo kwe-Encoder:
I-Encoder iyinhlanganisela esondelene yemishini neye-elekthronikhi yedivayisi yokulinganisa ngokunemba, isignali noma idatha izofakwa ikhodi, ukuguqulwa, yokuxhumana, ukudluliselwa kanye nokugcinwa kwedatha yesignali. Ngokwezici ezahlukene, ama-encoder ahlukaniswa kanje:
● Idiski yekhodi kanye nesilinganiso sekhodi. I-encoder eguqula ukufuduka okuqondile kube yisignali kagesi ibizwa ngokuthi isikali sekhodi, kanti leyo eguqula ukufuduka kwe-angular kube ukuxhumana ngezingcingo yidiski yekhodi.
● Ama-encoder akhulayo. Ihlinzeka ngolwazi olufana nendawo, i-engeli kanye nenani lokujika, futhi ichaza izinga elifanele ngenani lama-pulse ngokujika ngakunye.
● I-encoder ephelele. Ihlinzeka ngolwazi olufana nendawo, i-engeli, kanye nenani lokujika nge-anular increments, futhi i-angular increment ngayinye inikezwa ikhodi ehlukile.
● I-hybrid absolute encoder. I-hybrid absolute encoder ikhipha amasethi amabili olwazi: isethi eyodwa yolwazi isetshenziselwa ukuthola indawo ye-pole enomsebenzi wolwazi oluphelele, kanti enye isethi ifana ncamashi nolwazi lokukhipha lwe-incremental encoder.
Ama-encoder asetshenziswa kakhulu kuma-motors:
●Isifaki khodi esikhulayo
Ukusebenzisa ngqo isimiso sokuguqulwa kwe-photoelectric ukukhipha amasethi amathathu ama-pulse amagagasi ayisikwele u-A, u-B no-Z. Umehluko wesigaba phakathi kwamasethi amabili ama-pulse u-A no-B ungama-90o, ukuze isiqondiso sokujikeleza singahlulelwa kalula; isigaba se-Z siyi-pulse eyodwa ngokujikeleza ngakunye futhi sisetshenziselwa ukubeka iphuzu lokubhekisela. Izinzuzo: ukwakhiwa kwesimiso esilula, impilo ejwayelekile yemishini ingaba ngaphezu kwamahora angamashumi ezinkulungwane, ikhono eliqinile lokulwa nokuphazamiseka, ukuthembeka okuphezulu, futhi kufanelekile ukudlulisa ibanga elide. Okubi: ukungakwazi ukukhipha ulwazi oluphelele lwesikhundla sokujikeleza kweshaft.
● Isifaki khodi esiphelele
Kuneziteshi eziningana zekhodi eziqondile eceleni kwendlela ye-radial epuletini lekhodi eliyindilinga lenzwa, futhi isiteshi ngasinye sakhiwe yimikhakha edlulisa ukukhanya nengadlulisi ukukhanya, futhi inani lemikhakha yeziteshi zekhodi eziseduze liphindwe kabili, kanti inani leziteshi zekhodi epuletini lekhodi liyinani lezinombolo ezimbili. Uma ipuleti lekhodi lisezikhundleni ezihlukene, isici ngasinye esizwela ukukhanya siguqulwa sibe isignali yezinga ehambisanayo ngokuya ngokukhanya noma cha, okwenza inombolo ye-binary.
Lolu hlobo lwe-encoder lubonakala ngokuthi akukho khawunta edingekayo futhi ikhodi yedijithali eqondile ehambisana nendawo ingafundwa kunoma yisiphi isikhundla se-rotary axis. Ngokusobala, uma iziteshi zekhodi ziningi, kulapho isinqumo siphezulu khona, futhi ku-encoder ene-N-bit binary resolution, idiski yekhodi kumele ibe neziteshi zekhodi ze-N. Njengamanje, kunemikhiqizo ye-absolute encoder ye-16-bit eShayina.
3, isimiso sokusebenza se-encoder
Ngediski yekhodi ye-photoelectric ene-axis phakathi nendawo, kunemigqa yokubhala eyindilinga kanye nemigqa emnyama, futhi kunemishini yokudlulisa nokwamukela i-photoelectric yokuyifunda, futhi amaqembu amane ezibonakaliso ze-sine wave ahlanganiswa abe yi-A, B, C kanye ne-D. Igagasi ngalinye le-sine lihlukile ngomehluko wesigaba sama-degrees angu-90 (ama-degrees angu-360 uma kuqhathaniswa negagasi elijikelezayo), kanti izimpawu ze-C kanye ne-D zibuyiselwa emuva futhi zibekwe ngaphezulu kwezigaba ze-A kanye ne-B, ezingathuthukisa isignali ezinzile; kanti enye i-pulse yesigaba se-Z ikhishwa ngokujikeleza ngakunye ukuze imele isikhundla sokubhekisela sesikhundla esingu-zero.
Njengoba izigaba ezimbili u-A no-B zihlukile ngama-degree angu-90, kungaqhathaniswa ukuthi isigaba A singaphambili noma isigaba B singaphambili ukuze kubonwe ukujikeleza phambili nokuhlehla kwe-encoder, futhi i-zero reference bit ye-encoder ingatholakala nge-zero pulse. Izinto zepuleti lekhodi ye-encoder ziyingilazi, insimbi, ipulasitiki, ipuleti lekhodi yengilazi libekwe emgqeni oqoshiwe omncane kakhulu wengilazi, ukuzinza kwayo kokushisa kuhle, ukunemba okuphezulu, ipuleti lekhodi yensimbi ngqo ukuze lidlule hhayi umugqa oqoshiwe, hhayi obuthakathaka, kodwa ngoba insimbi inobukhulu obuthile, ukunemba kunqunyelwe, ukuzinza kwayo kokushisa kukhulu kakhulu kunengilazi, ipuleti lekhodi yepulasitiki lingabizi, izindleko zalo ziphansi, kodwa ukunemba, ukuzinza kokushisa, impilo imbi.
Isixazululo - isifaki khodi sokunikeza ukuthi zingaki imigqa eqoshiwe noma emnyama ngamadigri angu-360 okujikeleza ibizwa ngokuthi isixazululo, esaziwa nangokuthi inkomba yesisombululo, noma ngokuqondile ukuthi zingaki imigqa, ngokuvamile emigqeni engu-5 ~ 10000 ngokufaka inkomba ngokujikeleza ngakunye.
4, Isimiso sokulinganisa isikhundla kanye nokulawula impendulo
Ama-encoder athatha isikhundla esibaluleke kakhulu kuma-lifti, amathuluzi omshini, ukucubungula izinto, izinhlelo zokuphendula kwezimoto, kanye nasemishinini yokulinganisa nokulawula. I-encoder isebenzisa i-grating kanye nomthombo wokukhanya we-infrared ukuguqula isignali yokukhanya ibe isignali kagesi ye-TTL (HTL) nge-receiver. Ngokuhlaziya imvamisa yezinga le-TTL kanye nenani lamazinga aphezulu, i-engeli yokujikeleza kanye nendawo yokujikeleza yemoto kuboniswa ngokubonakalayo.
Njengoba i-engeli kanye nendawo kungalinganiswa ngokunembile, i-encoder kanye ne-inverter kungakhiwa kube uhlelo lokulawula oluvaliwe ukuze kwenziwe ukulawula kube okunembe kakhudlwana, yingakho ama-lifti, amathuluzi omshini, njll. kungasetshenziswa ngokunembe kangaka.
5, Isifinyezo
Ngamafuphi, siyaqonda ukuthi ama-encoder ahlukaniswe ngokwezinga eliqhubekayo neliphelele ngokwesakhiwo sawo, futhi womabili aguqula amanye amasignali, njengezibonakaliso ze-optical, abe amasignali kagesi angahlaziywa futhi alawulwe. Ama-lifti avamile namathuluzi omshini empilweni yethu asekelwe ekulungisweni okunembile kwenjini, futhi ngokulawulwa kwe-feedback closed-loop kwesignali kagesi, i-encoder ene-inverter nayo iyindlela yemvelo yokufeza ukulawula okunembile.
