Yintoni i-encoder?
Ngexesha lokusebenza kwemoto, ukujonga iiparameter ngexesha langempela ezifana nombane, isantya sokujikeleza, kunye nendawo ehambelanayo yecala elijikelezayo leshafti ejikelezayo kumisela imeko yeimotoumzimba kunye nezixhobo ezirhuqwayo, kunye nolawulo lwangempela lwemoto kunye neemeko zokusebenza kwesixhobo, ngaloo ndlela kufezekiswa i-servoing, ulawulo lwesantya, kunye neminye imisebenzi emininzi ethile.
Apha, ukusetyenziswa kwe-encoder njengento yokulinganisa engaphambili akupheleli nje ekwenzeni lula inkqubo yokulinganisa, kodwa ikwachanekile, ithembekile kwaye inamandla.
I-Encoder sisixhobo sokubona esijikelezayo esiguqula indawo kunye nokususwa kweendawo ezijikelezayo zibe luchungechunge lwemiqondiso ye-digital pulse, eqokelelwa kwaye icutshungulwe yinkqubo yolawulo ukuze ikhuphe uthotho lwemiyalelo yokulungisa nokutshintsha imeko yokusebenza kwesixhobo. Ukuba i-encoder idityaniswe ne-gear bar okanye i-screw screw, ingasetyenziselwa ukulinganisa ubungakanani bendawo kunye nokususwa kweendawo ezihambayo ezithe ngqo.
Uhlu olusisiseko lwe-encoder
I-Encoder yindibaniselwano esondeleyo yoomatshini kunye neye-elektroniki yezixhobo zokulinganisa ngokuchanekileyo, isignali okanye idatha yokubhala ikhowudi, ukuguqula, yonxibelelwano, ukuhambisa kunye nokugcina idatha yesignali.
I-encoder sisixhobo sokulinganisa ngokuchanekileyo esidibanisa izinto zoomatshini neze-elektroniki ukuze zifake ikhowudi, ziguqule, zinxibelelane, zidlulisele kwaye zigcine imiqondiso kunye nedatha. Ngokweempawu ezahlukeneyo, ulwahlulo lwe-encoder lulandelayo: i-code disc kunye ne-code scale: ukufuduka okuthe ngqo kwiisignali zombane ezibizwa ngokuba yi-code scale encoder, ukufuduka kwe-angular kwi-telecommunications kwi-code disc, - i-incremental encoder: ukubonelela ngendawo, i-angle kunye nenani lee-laps, njl.njl., kwinani lee-pulses ngokujika nganye ukuchaza isantya sokwahluka. -I-absolute encoder: Nika ulwazi olufana nendawo, i-angle kunye nenani lee-revolutions kwi-angular increments, i-angular increment nganye inikwa ikhowudi eyahlukileyo.
-Ii-encoders ezipheleleyo ze-hybrid: Ii-encoders ezipheleleyo ze-hybrid zivelisa iiseti ezimbini zolwazi: iseti enye yolwazi isetyenziselwa ukubona indawo yee-poles zemagnethi, kunye nomsebenzi wolwazi olupheleleyo; enye iseti ifana nqwa nolwazi lwemveliso lwee-encoders ezikhulayo.
Ii-encoders ezisetyenziswa rhoqo kwiiimoto
I-encoder eyongeziweyo
Ukusebenzisa ngokuthe ngqo umgaqo wokuguqulwa kwe-photoelectric ukuya kwimveliso yeeseti ezintathu zeepulses zesikwere ze-A, B kunye ne-Z. A, B iiseti ezimbini zeepulses umahluko wesigaba se-90o, unokumisela ngokulula indlela yokujikeleza; Isigaba se-Z sijika ipulse nganye, sisetyenziselwa ukubeka indawo yereferensi. Iingenelo: umgaqo olula wokwakha, ubomi obuqhelekileyo boomatshini bungamashumi amawaka eeyure nangaphezulu, amandla aqinileyo okulwa nokuphazamiseka, ukuthembeka okuphezulu, okufanelekileyo ekudluliseni umgama omde. Iingxaki: ukungakwazi ukukhupha ulwazi olupheleleyo lwendawo yokujikeleza kweshaft.
Iikhowudi ezipheleleyo
I-sensor yedijithali ephuma ngqo, i-sensor ikhowudi yediski ejikelezayo ecaleni kwendlela ye-radial yeendlela ezininzi zekhowudi ezixineneyo, itshaneli nganye ngamacandelo akhanyayo angabonakaliyo kwaye angangeni kukhanya phakathi kokwakhiwa kwenani lamacandelo etshaneli yekhowudi akufutshane lulwalamano oluphindwe kabini phakathi kwenani leendlela zekhowudi kwi-disc yekhowudi linani lamanani e-binary kwinani leendlela zekhowudi linani leebhithi ze-disc yayo yekhowudi, kwi-disc yekhowudi ecaleni lomthombo wokukhanya, elinye icala elihambelana netshaneli nganye yekhowudi kukho into ebonakala kukukhanya; xa i-disc yekhowudi ikwindawo eyahlukileyo, into ebonakala kukukhanya iguqula isignali yenqanaba elihambelanayo ukuze yenze inombolo ye-binary. Xa i-disc yekhowudi ikwiindawo ezahlukeneyo, into nganye ebonakala kukukhanya iguqula isignali yenqanaba elihambelanayo ngokwesibane okanye hayi ukuze yenze inombolo ye-binary.
Olu hlobo lwe-encoder luphawulwa kukuba alufuni khawuntara kwaye ikhowudi yedijithali esisigxina ehambelana nendawo inokufundwa kuyo nayiphi na indawo yeshaft ejikelezayo. Ngokucacileyo, okukhona itshaneli yekhowudi iphezulu, kokukhona isisombululo siphezulu, kwi-encoder enesisombululo se-N-bit binary, idiski yekhowudi kufuneka ibe netshaneli yebhakhowudi ye-N. Okwangoku, kukho iimveliso ze-encoder ezipheleleyo ze-16-bit.
Umgaqo wokusebenza we-encoder
Ngaphakathi kwesiseko esine-shaft yepleyiti yekhowudi ye-photoelectric, enesangqa esidlula kwimigca emnyama, kukho izixhobo zokudlulisela kunye nezamkeli ze-photoelectric ekufuneka zifundwe, ukuze kufunyanwe iiseti ezine zemiqondiso ye-sine wave edityaniswe kwi-A, B, C, D, i-sine wave nganye enomahluko wesigaba sama-90 degrees (xa kuthelekiswa ne-circumferential wave ye-360 degrees), i-C, D signal inversion, ebekwe kwi-A, B two-phase, enokuphuculwa ukuze kuzinziswe isignali; kwaye enye ijika nganye ukuze ikhuphe i-Z-phase pulse egameni le-zero position Reference position.
Njengoko umahluko phakathi kwe-A ne-B kwisigaba sesibini se-90 degrees, unokuthelekiswa nesigaba se-A esingaphambili okanye isigaba se-B esingaphambili, ukuze ubone ukujikeleza okuhle nokujika okungasemva kwe-encoder, nge-zero pulse, ungafumana indawo yesalathiso se-zero ye-encoder.
Izinto zediski ye-Encoder zineglasi, isinyithi, iplastiki, idiski yeglasi ibekwe kwiglasi kumgca obhityileyo kakhulu oqingqiweyo, uzinzo lwayo lobushushu lulungile, luchanekile kakhulu, idiski yesinyithi idlula ngqo kwaye ingadluli kumgca oqingqiweyo, ayibuthathaka, kodwa ngenxa yobukhulu obuthile besinyithi, ukuchaneka kulinganiselwe, kwaye uzinzo lwayo lobushushu luya kuba lubi kuneglasi yomyalelo wobukhulu, idiski yeplastiki iyonga, ixabiso layo liphantsi, kodwa ukuchaneka, uzinzo lobushushu, ixesha lokuphila libi kakhulu. Iidiski zeplastiki ziyonga, kodwa ukuchaneka, uzinzo lobushushu, kunye nexesha lokuphila libi kakhulu.
Isisombululo - i-encoder yokubonelela ngemigca emingaphi okanye emnyama nge-360 degrees yokujikeleza ibizwa ngokuba yi-resolution, eyaziwa ngokuba yi-resolution ye-index, okanye ebizwa ngokuthe ngqo ngokuba yimigca emingaphi, ngokubanzi yi-5 ~ 10,000 imigca nge-revolution index.
Imigaqo yokulinganisa isikhundla kunye nolawulo lwempendulo
Ii-encoders zithatha indawo ebaluleke kakhulu kwiilifti, izixhobo zoomatshini, ukucubungula izinto, iinkqubo zempendulo yeemoto kunye nezixhobo zokulinganisa nokulawula. Ii-encoders zisebenzisa ii-optical gratings kunye nemithombo yokukhanya ye-infrared ukuguqula ii-optical signals zibe ziisignali zombane ze-TTL (HTL) nge-receiver, ebonisa ngokubonakalayo i-engile yokujikeleza kunye nendawo yemoto ngokuhlalutya i-frequency yenqanaba le-TTL kunye nenani lamanqanaba aphezulu.
Njengoko i-engile kunye nendawo zinokulinganiswa ngokuchanekileyo, kunokwenzeka ukwenza inkqubo yolawulo oluvaliweyo olune-encoder kunye ne-inverter ukwenza ulawulo lube ngokuchanekileyo nangakumbi, yiyo loo nto iilifti, izixhobo zomatshini, njl.njl. zingasetyenziswa ngokuchanekileyo.
Isishwankathelo
Ngamafutshane, siyaqonda ukuba i-encoder yahlulwe yaba ziintlobo ezimbini ezilandelelanayo nezipheleleyo ngokwesakhiwo, zikwayiminye imiqondiso, efana nemiqondiso ye-optical, ibe yimiqondiso yombane enokuhlaziywa nokulawulwa. Kwaye siphila kwi-lift eqhelekileyo, izixhobo zomatshini zisekelwe nje kulawulo oluchanekileyo lwemoto, ngempendulo yolawulo lwesignali yombane oluvaliweyo, i-encoder ene-frequency converter nayo yinto enokwenzeka ukuze kufezekiswe ulawulo oluchanekileyo.
