1, Yintoni i-encoder
Ngexesha lokusebenza kwe-aWorm gearbox N20 DC motor, iiparamitha ezinje ngoku, isantya kunye nendawo ehambelanayo yendlela ejikelezayo ye-shaft ejikelezayo ibekwe esweni ngexesha lokwenyani ukumisela imeko yemoto yomzimba kunye nesixhobo esirhuqwayo, kwaye ngaphezu koko ukulawula iimeko zokusebenza kwemoto kunye nezixhobo ngexesha lokwenyani, ngaloo ndlela ukuqonda imisebenzi emininzi efana ne-servo kunye nommiselo wesantya. Apha, ukusetyenziswa kwe-encoder njengento yokulinganisa isiphelo-ngaphambili ayenzi lula kakhulu inkqubo yokulinganisa, kodwa ichanekile, ithembekile kwaye inamandla. I-encoder i-sensor ye-rotary eguqula ubuninzi bomzimba wesikhundla kunye nokufuduka kwamacandelo ajikelezayo kwi-series ye-digital pulse signals, eqokelelwa kwaye iqhutywe yinkqubo yokulawula ukukhupha uluhlu lwemiyalelo yokulungelelanisa nokutshintsha imeko yokusebenza kwesixhobo. Ukuba i-encoder idityaniswe nebar yegiya okanye isikrufu sokujija, ingasetyenziselwa ukulinganisa indawo kunye nokufuduswa kwamalungu ahambayo ahambayo.
2, ulwahlulo lwe-encoder
Ulwahlulo olusisiseko lweKhowuwudi:
I-encoder yindibaniselwano esondeleyo yomatshini kunye ne-elektroniki yesixhobo sokulinganisa ngokuchanekileyo, isignali okanye idatha iya kufakwa ngekhowudi, ukuguqulwa, ukunxibelelana, ukuhanjiswa kunye nokugcinwa kwedatha yesignali. Ngokweempawu ezahlukeneyo, iikhowudi zihlelwa ngolu hlobo lulandelayo:
● Idiskhi yekhowudi kunye nesikali sekhowudi. I-encoder eguqula i-linear displacement ibe yisignali yombane ibizwa ngokuba yi-code scale, kwaye lowo uguqula ukufuduka kwe-angular kwi-telecommunication yi-code disc.
● Iikhowudi ezongezekayo. Inika ulwazi olunjengendawo, i-engile kunye nenani lokujika, kwaye ichaza ireyithi efanelekileyo ngenani lee-pulses kwi-turn nganye.
● Isifakeli-khowudi esipheleleyo. Inika ulwazi olufana nesikhundla, i-engile, kunye nenani lokujika kwi-angular increments, kwaye i-angular increment nganye inikwe ikhowudi eyodwa.
● iHybrid absolute encoder. Umhlanganiselwa ogqibeleleyo weekhowudi ukhupha iiseti ezimbini zolwazi: iseti enye yolwazi isetyenziselwa ukubona indawo yepali enomsebenzi wolwazi olupheleleyo, kwaye enye iseti iyafana ncakasana nolwazi oluphumayo lwe-encoder eyongezayo.
Iikhowudi ezisetyenziswa rhoqo kwiinjini:
●I-encoder eyongeziweyo
Ngokuchanekileyo usebenzisa umgaqo wokuguqulwa kwe-photoelectric ukuvelisa iiseti ezintathu ze-square wave pulses A, B kunye no-Z. Umahluko wesigaba phakathi kweeseti ezimbini ze-pulses A kunye ne-B yi-90o, ukwenzela ukuba ulwalathiso lokujikeleza lukwazi ukugwetywa lula; Inqanaba lika-Z yi-pulse enye kwi-revolution kwaye isetyenziselwa ukubeka indawo yesalathiso. Izinto eziluncedo: ulwakhiwo olulula lomgaqo, ubomi obuqhelekileyo boomatshini bunokuba ngaphezulu kwamashumi amawaka eeyure, isakhono esinamandla sokuchasana nokuphazamiseka, ukuthembeka okuphezulu, kwaye kufanelekile ukuhanjiswa komgama omde. Ukungalungi: ayikwazi ukuvelisa ulwazi lwendawo epheleleyo yokujikeleza kweshaft.
● Isifakeli-khowudi esipheleleyo
Kukho iziteshi ezininzi zekhowudi ye-concentric ecaleni kwendlela ye-radial kwi-plate yekhowudi yesetyhula ye-sensor, kwaye ishaneli nganye iqulunqwe ngamacandelo okuhambisa ukukhanya kunye nokungadlulisi ukukhanya, kunye nenani lamacandelo eendlela ezikufutshane zekhowudi ziphindwe kabini, kwaye inani leendlela zekhowudi kwiplati yekhowudi linani leedijithi zokubini. Xa ipleyiti yekhowudi ikwizikhundla ezahlukeneyo, into nganye ye-photosensitive iguqulelwa kwisignali yezinga elihambelanayo ngokuhambelana nokukhanya okanye cha, ukwenza inombolo yokubini.
Olu hlobo lwe-encoder lubonakaliswa yinyaniso yokuba akukho counter efunekayo kwaye ikhowudi yedijithali esisigxina ehambelana nendawo inokufundwa kuyo nayiphi na indawo ye-axis ejikelezayo. Ngokucacileyo, iitshaneli ezininzi zekhowudi, ziphezulu isisombululo, kunye ne-encoder ene-N-bit yesisombululo sokubini, idisk yekhowudi kufuneka ibe ne-N code channels. Okwangoku, kukho i-16-bit epheleleyo yeemveliso ze-encoder e-China.
3, umgaqo osebenzayo we-encoder
Nge-disk yekhowudi ye-photoelectric ene-axis embindini, kukho ukupasa okusetyhula kunye nemigca ebhaliweyo emnyama kuyo, kwaye kukho i-photoelectric yokudlulisa kunye nokufumana izixhobo zokuyifunda, kunye namaqela amane emiqondiso ye-sine wave idityanisiwe ibe yi-A, B, C kunye ne-D. I-sine wave wave iyahluka nge-90 degrees umehluko wesigaba (i-360 degrees ngokumalunga ne-circumferential wave kunye ne-Drug redverse), kunye ne-C. ukwandisa umqondiso ozinzileyo; kunye nesinye isigaba se-Z se-pulse siphuma kwi revolution nganye ukumela indawo yereferensi enguziro.
Njengoko izigaba ezibini ze-A kunye ne-B zihluke ngee-degrees ezingama-90, zinokuthelekiswa nokuba isigaba A singaphambili okanye isigaba B singaphambili ukuqonda ukujikeleza kwangaphambili kunye nokubuyisela umva kwe-encoder, kunye ne-zero ye-reference bit ye-encoder inokufumaneka nge-pulse ye-zero. Ikhowudi yekhowudi ye-encoder izixhobo zeglasi, intsimbi, iplastiki, iplate yeglasi ifakwe kwiglasi encinci kakhulu, ukuqina kwayo kwe-thermal kulungile, ukuchaneka okuphezulu, iplate yekhowudi yentsimbi ngokuthe ngqo ukudlula kwaye ayikrolwanga umgca, kungekhona ubuthathaka, kodwa ngenxa yokuba isinyithi sinobunzima obuthile, ukuchaneka kulinganiselwe, ukuzinza kwayo kwe-thermal ngumyalelo wobungakanani beplate ephantsi, kodwa i-plate yeplastiki ibiza kakhulu, i-plate ye-plastic iphantsi, ikhowudi yeplastiki, ikhowudi yeplastiki, ikhowudi yeplastiki. uzinzo thermal, ubomi amahlwempu Abanye.
Isisombululo - i-encoder yokubonelela ukuba mingaphi na okanye imigca ekroliweyo emnyama nge-360 degrees yokujikeleza ibizwa ngokuba yi-solution, ekwaziwa njenge-resolution indexing, okanye ngokuthe ngqo ukuba mingaphi imigca, ngokubanzi kwimigca emi-5 ukuya kwe-10000 ngesalathiso senguquko nganye.
4, Umlinganiselo wesikhundla kunye nomgaqo wokulawula impendulo
Ii-encoders zikwindawo ebaluleke kakhulu kwizinyusi, izixhobo zoomatshini, ukusetyenzwa kwemathiriyeli, iinkqubo zengxelo yeemoto, kunye nakwisixhobo sokulinganisa kunye nokulawula. I-encoder isebenzisa i-grating kunye nomthombo wokukhanya kwe-infrared ukuguqula isignali ye-optical ibe ngumqondiso wombane we-TTL (HTL) ngokusebenzisa umamkeli. Ngokuhlalutya ukuphindaphinda kwinqanaba le-TTL kunye nenani lamanqanaba aphezulu, i-angle yokujikeleza kunye nesikhundla sokujikeleza kwemoto ibonakaliswe ngokubonakalayo.
Ekubeni i-angle kunye nesikhundla sinokulinganiswa ngokuchanekileyo, i-encoder kunye ne-inverter inokuqulunqwa kwinkqubo yokulawula i-loop evaliweyo ukwenza ulawulo oluchanekileyo, yingakho i-elevators, izixhobo zomatshini, njl.
5, Isishwankathelo
Isishwankathelo, siyaqonda ukuba i-encoders ihlulwe ngokunyuka kwaye ngokupheleleyo ngokwesakhiwo sabo, kwaye bobabini baguqula ezinye iimpawu, njengezibonakaliso ze-optical, zibe yimiqondiso yombane enokuthi ihlalutywe kwaye ilawulwe. Izinyusi eziqhelekileyo kunye nezixhobo zoomatshini ebomini bethu zisekwe kuhlengahlengiso oluchanekileyo lwemoto, kwaye ngolawulo oluvaliweyo lwe-loop yesiginali yombane, i-encoder ene-inverter ikwayindlela yendalo yokufezekisa ulawulo oluchanekileyo.
