Intshayelelo kunye nokuhlelwa kweekhowudi

An umfaki khowudisisixhobo esiqokelela kunye nokuguqula isignali (efana ne-bit stream) okanye idatha ibe yifomu yomqondiso enokusetyenziselwa unxibelelwano, ugqithiso kunye nokugcinwa.I-encoder iguqula i-angular displacement okanye i-linear displacement ibe yisignali yombane, eyokuqala ibizwa ngokuba yi-code disc, kwaye le yokugqibela ibizwa ngokuba yi-yardstick.Ngokwendlela yokufunda, i-encoder inokwahlulwa ibe ziindidi ezimbini: uhlobo loqhagamshelwano kunye nohlobo olungaqhagamshelwanga;ngokomgaqo wokusebenza, i-encoder inokohlulwa ibe ziindidi ezimbini: uhlobo olongezelekayo kunye nohlobo olupheleleyo.I-encoder eyongeziweyo iguqula i-displacement ibe ngumqondiso wombane wexesha elithile, kwaye emva koko iguqule isignali yombane ibe yi-pulse yokubala, kwaye isebenzisa inani lee-pulses ukumela ubukhulu bokufuduka.Isikhundla ngasinye se-encoder esipheleleyo sihambelana nekhowudi ethile yedijithali, ngoko isalathisi sayo sinxulumene kuphela neendawo zokuqala kunye nesiphelo somlinganiselo, kodwa akukho nto yakwenza nenkqubo ephakathi yokulinganisa.

Ukuhlelwa kweekhowudi
Ngokomgaqo-siseko wokufumanisa, i-encoder inokohlulwa ibe luhlobo lwe-optical, uhlobo lwemagnethi, uhlobo lwe-inductive kunye nohlobo lwe-capacitive.Ngokwendlela yayo yokulinganisa kunye nefom yesiphumo somqondiso, inokwahlulwa ibe ziindidi ezintathu: uhlobo olunyukayo, uhlobo olupheleleyo kunye nohlobo oluxubileyo.
Isifaki khowudi esongezelelweyo:

I-encoder eyongeziweyoisebenzisa ngokuthe ngqo umgaqo wokuguqulwa kweefoto zombane ukuvelisa amaqela amathathu ee-square wave pulses A, B kunye ne-Z isigaba;Umahluko wesigaba phakathi kwamaqela amabini e-pulses A kunye ne-B yi-90 degrees, ukwenzela ukuba isalathiso sokujikeleza sigwetywe ngokulula, ngelixa iSigaba Z i-pulse enye nge-revolution, esetyenziselwa ukubeka indawo yereferensi.Izibonelelo zayo ziyimigaqo elula kunye nesakhiwo, umyinge wobomi bomatshini unokuba ngaphezu kwamashumi amawaka eeyure, amandla anamandla okuchasana nokuphazamiseka, ukuthembeka okuphezulu, kunye nokulungelelaniswa komgama omde.
Isifaki khowudi esipheleleyo:

I-Absolute encoder yinzwa yoluvo ekhupha amanani ngokuthe ngqo.Kwidiskhi yayo yekhowudi esetyhula, kukho iidiski ezininzi zekhowudi ezigxininisiweyo ecaleni kwendlela yeradial.Imithi yecandelo lomzila wekhowudi inobudlelwane obubini.Inani lekhowudi yeengoma kwidiskhi yekhowudi linani lamadijithi enani layo lokubini.Kwelinye icala lekhowudi idisc ngumthombo wokukhanya, kwaye kwelinye icala kukho i-photosensitive element ehambelana nomzila wekhowudi nganye.Xa ikhowudi Xa idiski ikwizikhundla ezahlukeneyo, into nganye ye-photosensitive iguqula isignali yenqanaba ehambelanayo nokuba ikhanyisiwe okanye ayikhanyi, yenza inombolo yokubini.Isici sale encoder kukuba akukho counter efunekayo, kwaye ikhowudi yedijithali esisigxina ehambelana nendawo inokufundwa kuyo nayiphi na indawo ye-shaft ejikelezayo.
I-Hybrid Absolute Encoder:

I-Hybrid absolute encoder, ikhupha iiseti ezimbini zolwazi, iseti enye yolwazi isetyenziselwa ukubona indawo yepoleni yamagnetic, kunye nomsebenzi wolwazi olupheleleyo;enye iseti iyafana kanye neenkcukacha zemveliso ye encoder eyongezelekayo.
