Yintoni isifaki khowudi?
Ngexesha lokusebenza kwemoto, ukujonga ixesha lokwenyani kwiiparamitha ezinje ngoku, isantya sokujikeleza, kunye nesikhundla esihambelanayo somda ojikelezayo we-shaft ejikelezayo imisela imekoimotoumzimba kunye nezixhobo ezirhuqwayo, kwaye ngaphezu koko, ulawulo lwexesha lokwenyani lwemoto kunye neemeko zokusebenza kwesixhobo, ngaloo ndlela ukuqonda ukusevisa, ukulawulwa kwesantya, kunye neminye imisebenzi emininzi ethile.
Apha, usetyenziso lwe-encoder njengesiseko somlinganiselo wesiphelo ayenzi lula kakhulu inkqubo yokulinganisa kuphela, kodwa ichanekile, ithembekile kwaye inamandla.
I-encoder i-sensor ejikelezayo eguqula indawo 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, isenokusetyenziswa ukulinganisa ubungakanani bomzimba bendawo kunye nokufuduswa kwamalungu ahambayo ahambayo.
Ulwahlulo olusisiseko lwe-encoder
I-encoder yindibaniselwano esondeleyo yomatshini kunye ne-elektroniki yezixhobo zokulinganisa ngokuchanekileyo, isignali okanye idatha yekhowudi, ukuguqulwa, ukunxibelelana, ukuhanjiswa kunye nokugcinwa kwedatha yesignali.
I-encoder sisixhobo sokulinganisa ngokuchanekileyo esidibanisa amacandelo omatshini kunye ne-elektroniki ukubethelela, ukuguqula, ukunxibelelana, ukuthumela nokugcina iimpawu kunye nedatha. Ngokweempawu ezahlukeneyo, ukuhlelwa kwe-encoder ngolu hlobo lulandelayo: i-code disc kunye ne-code scale: ukufuduka komgca kwiimpawu zombane ezibizwa ngokuba yi-code scale encoder, i-angular displacement kwi-telecommunications ye-code disc, - i-encoder eyongezelelweyo: ukubonelela ngesikhundla, i-angle kunye nenani leempuphu, njl. -Absolute encoder: Ukubonelela ngolwazi olufana nendawo, i-angle kunye nenani lee-revolutions kwi-angular increments, i-angular increment nganye inikwa ikhowudi ekhethekileyo.
-I-Hybrid absolute encoders: I-Hybrid absolute encoders ikhupha iiseti ezimbini zolwazi: isethi enye yolwazi isetyenziselwa ukufumanisa indawo yeepali zamagnetic, kunye nomsebenzi wolwazi olupheleleyo; enye iseti iyafana ncakasana nolwazi lwemveliso yeekhowudi ezongezelelekileyo.
Iikhowudi ezisetyenziswa ngokuqhelekileyo zeiinjini
I-encoder eyongeziweyo
Ngokuthe ngqo usebenzisa umgaqo wokuguqulwa kwe-photoelectric ukuvelisa iiseti ezintathu ze-square wave pulses A, B kunye ne-Z. A, B iiseti ezimbini ze-pulses isigaba umehluko we-90o, unokugqiba ngokulula ulwalathiso lokujikeleza; Z-isigaba ngasinye i-pulse, isetyenziselwa ukubeka indawo yesalathiso. Izinto eziluncedo: umgaqo olula wokwakha, umyinge wobomi bomatshini wamashumi amawaka eeyure okanye ngaphezulu, isakhono esinamandla sokuchasana nokuphazamiseka, ukuthembeka okuphezulu, okufanelekileyo ukuhanjiswa komgama omde. Ukungalungi: ayikwazi ukuvelisa ulwazi lwendawo epheleleyo yokujikeleza kweshaft.
Iikhowudi ezipheleleyo
Isivamvo sedijithali esiphuma ngokuthe ngqo, isivamvo sesetyhula sediski ecaleni kwendlela yeradial yenani lamatshaneli ekhowudi agxininisiweyo, itshaneli ngalinye ngamacandelo angafihliyo kunye nokukhanya okungenakuchaphazeleka phakathi kokwakhiwa kwenani lamacandelo ekhowudi esecaleni esecaleni kubudlelwane obuphindwe kabini phakathi kwenani lamatshaneli ekhowudi kwidisc yekhowudi linani lamadijithi okubini kwinani lamatshaneli ekhowudi linani lediski yecala lekhowudi yomthombo, kwelinye icala lekhowudi yomthombo wediski, kwelinye icala lekhowudi yomthombo wayo. ehambelana nomjelo wekhowudi nganye kukho into enovakalelo olukhanyayo; xa i-disc yekhowudi ikwindawo eyahlukileyo, into enobunzima bokukhanya ngokokukhanya okanye ungaguquli isignali yezinga elihambelanayo ukwenza inombolo yebhinari. Xa idisc yekhowudi ikwizikhundla ezahlukeneyo, into nganye ye-photosensitive iguqula isignali yenqanaba elihambelanayo nokuba ikhanyisile okanye ayikhanyiyo ukwenza inombolo yokubini.
Olu hlobo lwe-encoder lubonakaliswe yinyaniso yokuba ayifuni i-counter kunye nekhowudi yedijithali esisigxina ehambelana nendawo inokufundwa kuyo nayiphi na indawo ye-shaft ejikelezayo. Ngokucacileyo, ngakumbi itshaneli yekhowudi, iphezulu isisombululo, kwi-encoder ene-N-bit yesisombululo sokubini, idisc yekhowudi kufuneka ibe neshaneli yebhakhowudi ye-N. Okwangoku, kukho i-16-bit epheleleyo yeemveliso ze-encoder.
Umgaqo wokusebenza we-encoder
Ngeziko eline-shaft ye-photoelectric code plate, enendandatho kwimigca emnyama, kukho i-photoelectric transmitter kunye nezixhobo zomamkeli ukufunda, ukufumana iiseti ezine zeempawu zamaza e-sine ezidityanisiweyo zibe yi-A, B, C, D, i-sine nganye yamaza kunye nokwahlukana kwesigaba se-90 degrees (ngokunxulumene ne-circumferential wave for the 360 degree signal in the C, D, D, 2000 degree inversion, i-D, i-B, i-D, i-D, inokuphuculwa ukuzinzisa umqondiso; kunye nelinye ithuba ngalinye ukukhupha ukubetha kwenqanaba elingu-Z egameni lendawo engu-0 yeReferensi.
Njengo-A, B umahluko wesigaba sesibini seedigri ezingama-90, unokuthelekiswa nesigaba A ngaphambili okanye isigaba B ngaphambili, ukuze ubone i-encoder elungileyo kunye nokujikeleza umva, nge-pulse engu-zero, ungafumana indawo yereferensi ye-encoder's zero.
Izinto ze-encoder zediski zineglasi, isinyithi, iplastiki, idiski yeglasi ifakwe kwiglasi kumgca oqingqiweyo oqingqiweyo kakhulu, ukuzinza kwayo kwe-thermal kulungile, ukuchaneka okuphezulu, idiski yensimbi ngokuthe ngqo ukuba idlule kwaye ingadluli umgca oqingqiweyo, ungabi buthathaka, kodwa ngenxa yobunzima obuthile besinyithi, ukuchaneka kulinganiselwe, kwaye ukuzinza kwayo kwe-thermal kuya kuba kubi kakhulu kunoko kweglasi ye-glass ye-odolo ye-disc, kodwa i-plastiki ye-disc ye-odolo yezoqoqosho iphantsi, kodwa i-disc ye-plastiki iphantsi. ukuchaneka, ukuzinza kwe-thermal, ixesha lokuphila libi. Iidiski zeplastiki zinoqoqosho, kodwa ukuchaneka, ukuzinza kwe-thermal, kunye nobude bobomi bubi.
Isisombululo - ikhowudi yokufaka ikhowudi yokubonelela ukuba mingaphi na okanye imigca emnyama kwidigri ezingama-360 zojikelezo ibizwa ngokuba sisisombululo, ekwaziwa ngokuba sisisombululo sesalathiso, okanye ebizwa ngokuthe ngqo ukuba mingaphi na imigca, ngokubanzi 5 ~ 10,000 imigca kwirevolution index.
Umlinganiselo wesikhundla kunye neMigaqo yoLawulo lweeNgxelo
Iikhowudi zikwindawo ebaluleke kakhulu kwizinyusi, izixhobo zoomatshini, ukusetyenzwa kwemathiriyeli, iinkqubo zengxelo yeemoto kunye nomlinganiselo kunye nezixhobo zokulawula. Ii-encoders zisebenzisa i-optical gratings kunye nemithombo yokukhanya ye-infrared ukuguqula imiqondiso ye-optical kwi-TTL (HTL) imiqondiso yombane nge-receiver, ebonisa ngokubonakalayo i-engile yokujikeleza kunye nesikhundla semoto ngokuhlalutya ukuphindaphinda kwinqanaba le-TTL kunye nenani lamanqanaba aphezulu.
Njengoko i-angle kunye nesikhundla sinokulinganiswa ngokuchanekileyo, kunokwenzeka ukwenza inkqubo yokulawula i-loop evaliweyo kunye ne-encoder kunye ne-inverter ukwenza ulawulo luchaneke ngakumbi, yingakho ukunyuswa, izixhobo zomatshini, njl. zingasetyenziswa ngokuchanekileyo.
Isishwankathelo
Isishwankathelo, siyaqonda ukuba i-encoder ihlukaniswe kwiintlobo ezimbini ezikhulayo kunye nezipheleleyo ngokuhambelana nesakhiwo, nazo ezinye iimpawu, ezifana nezibonakaliso ze-optical, kwiimpawu zombane ezinokuhlalutywa kwaye zilawulwe. Kwaye siphila ekuphakameni okuqhelekileyo, izixhobo zoomatshini zisekwe nje kulawulo oluchanekileyo lwemoto, ngempendulo yomqondiso wombane ovaliweyo wolawulo, i-encoder ene-converter frequency ikwangumcimbi wokufezekisa ulawulo oluchanekileyo.
