1, Yintoni i-encoder
Ngexesha lokusebenza kweIbhokisi yegiya yeWorm N20 DC motor, iiparameter ezifana nombane, isantya kunye nendawo ehambelanayo yecala elijikelezayo leshaft ejikelezayo zijongwa ngexesha langempela ukuze kuchongwe imeko yomzimba wemoto kunye nezixhobo ezirhuqwayo, kwaye ngaphezu koko kulawulwe iimeko zokusebenza kwemoto kunye nezixhobo ngexesha langempela, ngaloo ndlela kufezekiswa imisebenzi emininzi ethile efana ne-servo kunye nolawulo lwesantya. Apha, ukusetyenziswa kwe-encoder njengento yokulinganisa yangaphambili akupheleli nje ekwenzeni lula inkqubo yokulinganisa, kodwa kukwachanekile, kuthembekile kwaye kunamandla. I-encoder sisiva esijikelezayo esiguqula ubungakanani bendawo kunye nokususwa kwezinto 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 indawo kunye nokususwa kwezinto ezihambayo ezithe ngqo.
2, udidi lwe-encoder
Udidi olusisiseko lwe-Encoder:
I-Encoder yindibaniselwano esondeleyo yomatshini kunye ne-elektroniki yesixhobo sokulinganisa ngokuchanekileyo, isignali okanye idatha iya kubhalwa, iguqulwe, ukuze inxibelelane, idlulisele kwaye igcinwe idatha yesignali. Ngokweempawu ezahlukeneyo, ii-encoder zahlulwe ngolu hlobo lulandelayo:
● Idiski yekhowudi kunye nesikali sekhowudi. I-encoder eguqula ukufuduka okuthe ngqo kube sisignali yombane ibizwa ngokuba sisikali sekhowudi, kwaye leyo iguqula ukufuduka kwe-angular kube lunxibelelwano yidiski yekhowudi.
● Iikhowudi ezinyuswayo. Ibonelela ngolwazi olufana nendawo, i-engile kunye nenani lokujika, kwaye ichaza isantya esifanelekileyo ngenani lee-pulses ngokujika ngakunye.
● I-encoder egqibeleleyo. Ibonelela ngolwazi olufana nendawo, i-engile, kunye nenani leenguqu kwii-angular increments, kwaye i-angular increment nganye inikwe ikhowudi eyahlukileyo.
● I-hybrid absolute encoder. I-hybrid absolute encoder ikhupha iiseti ezimbini zolwazi: iseti enye yolwazi isetyenziselwa ukubona indawo yepole enomsebenzi wolwazi olupheleleyo, kwaye enye iseti ifana nqwa nolwazi lwemveliso ye-incremental encoder.
Ii-encoders ezisetyenziswa kakhulu kwiimoto:
●I-encoder eyongezayo
Ukusebenzisa ngokuthe ngqo umgaqo wokuguqulwa kwe-photoelectric ukuvelisa iiseti ezintathu zeepulses zamaza ayisikwere u-A, u-B no-Z. Umahluko wesigaba phakathi kweeseti ezimbini zeepulses u-A no-B yi-90o, ukuze ulwalathiso lokujikeleza lukwazi ukugwetywa ngokulula; isigaba se-Z si-pulse enye ngokujikeleza kwaye sisetyenziselwa ukubeka indawo yereferensi. Iingenelo: ulwakhiwo oluqhelekileyo lomgaqo, ubomi obuqhelekileyo boomatshini bunokuba ngaphezulu kwamashumi amawaka eeyure, amandla aqinileyo okulwa nokuphazamiseka, ukuthembeka okuphezulu, kwaye kufanelekile ukudluliselwa komgama omde. Iingxaki: ukungakwazi ukukhupha ulwazi olupheleleyo lwendawo yokujikeleza kweshaft.
● I-encoder egqibeleleyo
Kukho iindlela ezininzi zekhowudi ezijijekileyo ecaleni kwendlela ye-radial kwipleyiti yekhowudi ejikelezayo yesensor, kwaye itshaneli nganye yenziwe ngamacandelo okuhambisa ukukhanya nalawo angadlulisi ukukhanya, kwaye inani lamacandelo eendlela zekhowudi ezikufutshane liphindwe kabini, kwaye inani leendlela zekhowudi kwipleyiti yekhowudi linani lamanani amabini. Xa ipleyiti yekhowudi ikwiindawo ezahlukeneyo, into nganye ebona ukukhanya iguqulwa ibe sisignali yenqanaba ehambelanayo ngokwesibane okanye hayi, nto leyo eyenza inani lesibini.
Olu hlobo lwe-encoder luphawulwa kukuba akukho khawuntara ifunekayo kwaye ikhowudi yedijithali esisigxina ehambelana nendawo inokufundwa nakweyiphi na indawo ye-rotary axis. Ngokucacileyo, okukhona iitshaneli zekhowudi zininzi, kokukhona isisombululo siphezulu, kwaye kwi-encoder enesisombululo se-N-bit binary, idiski yekhowudi kufuneka ibe neetshaneli zekhowudi ze-N. Okwangoku, kukho iimveliso ze-16-bit absolute encoder eTshayina.
3, umgaqo wokusebenza we-encoder
Ngediski yekhowudi ye-photoelectric ene-axis embindini, kukho imigca yokubhala ejikelezayo kunye nemigca emnyama yokubhala kuyo, kwaye kukho izixhobo zokudlulisa nezokwamkela i-photoelectric zokuyifunda, kwaye amaqela amane emiqondiso ye-sine wave adityaniswe kwi-A, B, C kunye ne-D. I-sine wave nganye yahlukile ngomahluko wesigaba se-90 degrees (ii-degrees ezingama-360 xa kuthelekiswa ne-circumferential wave), kwaye imiqondiso ye-C kunye ne-D ibuyiselwa umva kwaye ibekwe ngaphezulu kwizigaba ze-A kunye ne-B, ezinokuphucula isignali ezinzileyo; kwaye enye i-Z phase pulse iphuma kwi-revolution nganye ukuze imele indawo yesalathiso sendawo engu-zero.
Njengoko izigaba ezibini u-A no-B zahlukile ngama-90 degrees, kunokuthelekiswa nokuba isigaba u-A singaphambili okanye isigaba u-B singaphambili ukuze kubonwe ukujikeleza phambili nokujika okungasemva kwe-encoder, kwaye i-zero reference bit ye-encoder inokufumaneka nge-zero pulse. Izixhobo zeplate yekhowudi ye-encoder ziyiglasi, isinyithi, iplastiki, iplate yekhowudi yeglasi ibekwe kumgca oqingqiweyo weglasi obhityileyo kakhulu, uzinzo lwayo lobushushu lulungile, ukuchaneka okuphezulu, iplate yekhowudi yesinyithi ngqo ukuze idlule kwaye ayingomgca oqingqiweyo, ayibuthathaka, kodwa ngenxa yokuba isinyithi sinobukhulu obuthile, ukuchaneka kulinganiselwe, uzinzo lwayo lobushushu lubi kakhulu kuneglasi, iplate yekhowudi yeplastiki inoqoqosho, iindleko zayo ziphantsi, kodwa ukuchaneka, uzinzo lobushushu, ubomi abulunganga.
Isisombululo - i-encoder yokubonelela ngemigca emingaphi ebhalwe ngemigca okanye emnyama nge-360 degrees yokujikeleza ibizwa ngokuba yi-resolution, eyaziwa ngokuba yi-resolution indexing, okanye ngokuthe ngqo ukuba imigca emingaphi, ngokubanzi kwimigca emi-5 ~ 10000 ngokujikeleza ngakunye.
4, Umlinganiselo wesikhundla kunye nomgaqo wolawulo lwempendulo
Ii-encoders zithatha indawo ebaluleke kakhulu kwiilifti, izixhobo zoomatshini, ukucubungula izinto, iinkqubo zempendulo yeemoto, kunye nezixhobo zokulinganisa nokulawula. I-encoder isebenzisa i-grating kunye nomthombo wokukhanya we-infrared ukuguqula isignali ye-optical ibe sisignali yombane ye-TTL (HTL) nge-receiver. Ngokuhlalutya i-frequency yenqanaba le-TTL kunye nenani lamanqanaba aphezulu, i-engile yokujikeleza kunye nendawo yokujikeleza yemoto kuboniswa ngokubonakalayo.
Ekubeni i-engile kunye nendawo zinokulinganiswa ngokuchanekileyo, i-encoder kunye ne-inverter zinokwenziwa zibe yinkqubo yolawulo oluvaliweyo ukuze ulawulo luchaneke ngakumbi, yiyo loo nto ii-lifti, izixhobo zomatshini, njl.njl. zingasetyenziswa ngokuchanekileyo.
5, Isishwankathelo
Ngamafutshane, siyaqonda ukuba ii-encoders zahlulwe zibe zii-incremental kunye ne-absolute ngokwesakhiwo sazo, kwaye zombini ziguqula ezinye iisignali, ezifana neesignali ze-optical, zibe ziisignali zombane ezinokuhlalutywa kwaye zilawulwe. Ii-elevator eziqhelekileyo kunye nezixhobo zomatshini ebomini bethu zisekelwe kuhlengahlengiso oluchanekileyo lwe-motor, kwaye ngolawulo oluvaliweyo lwe-feedback lwesignali yombane, i-encoder ene-inverter ikwayindlela yendalo yokufumana ulawulo oluchanekileyo.
