Encoder - encoder olu ngu ...

Igama elithi "zokukhowuda" ine ngemvelaphi IsiNgesi. It oluvela encode ilizwi, oko kuthetha ntoni na "ukuguqula." Kubavelisi ezininzi ezaziwayo-kakuhle ngamazwe ezi zixhobo iintlobo ezaziwayo-kakuhle ezifana Siemens, SKB, HEIDENHAIN RLS, Baumer, EGULAYO AG, Balluff, Schneider yombane (Autonics Telemecanique), OMRON.

Ububanzi isicelo kunye nenjongo

Encoder - woluvo lisetyenziswa endle industrial lokuguqula ubuninzi ezilawulwa kube yimitha yombane. Ukusebenzisa oko uzimisele, umzekelo, isikhundla nomphini motor yombane. Ngenxa yokuba isixhobo ngasinye, apho usebenzisa i ujikeleza, ukuba ukuxhotyiswa kunye nesixhobo, ukuchaneka yokunqanda kwimimandla torque ezithandwayo lokusebenzisa transducers ezinjalo inkqubo entle ukufuduka. Eyona njongo apho zokukhowuda isetyenziswa, - yokukala engile ukujikeleza yento ngexesha ujikelezo. Encoders zibalulekile kule nkqubo imveliso kwi amashishini isixhobo umatshini, izakhiwo rabototehnicheskih. Basebenzisa ngendlela ezininzi mihla izixhobo yokulinganisa, efuna ubhaliso ngqo womlinganiselo we-engile ze ujikelezo, pan kunye nokujikeleza.

encoders simo

Zonke encoders kwaziwe azizahlulo yokusebenza ingundoqo kwandiswe, resistor, Imagnethi yomhlaba kunye nezibonwa ngenethwekhi mveliso okanye ibhasi interface.

Ngokuxhomekeke kumgaqo jikelele nokusebenza encoders ekwanti ngokugqibeleleyo liye likhula. Umahluko phakathi kwezi ntlobo zimbini lilele imisebenzi eyenziwa ngabo. Uluhlu lwemisebenzi kunye encoder nto kuthiwa uluhlu ngokubanzi kakhulu esigquma zokukhowuda liye likhula.

uguquko encoders

Le zakho zokukhowuda. Kwinkqubo ukuzitshintsha into pulses yayo imveliso ayinakutshintshwa, imali leyo umlinganiselo ngqo engile ukujikeleza into. Ngokuqhelekileyo, transducers eziye ezisetyenziswa izixhobo umatshini ukuze babhalise iintshukumo emboxo lwe shaft okanye iinkqubo automated kwi loop ingxelo umlinganiselo baze babhale isantya shaft ujikelezo.

Encoder kwandiswe - isixhobo ukusebenza ngenxa pulses eyenziwe data ukujikeleza. Inani la ngeyunithi ejikeleza nganye - oku engundoqo yokusebenza parameter kwefowuni. Ixabiso yangoku ukubonwa ngu menzi woluvo yi nendlela yokubala inani la ukusuka reference kuyo. Ukuze ubophe izakhelo ukuseta amanqaku reference ukubetha zokukhowuda, apho kuqalwa emva kokutshintshela ngezinto zokusebenza. Ukumiselwa data usebenzisa kwandiswe transducer kunokwenzeka kuphela ngexesha ukujikeleza okanye ekujikeni. Xa ukujikeleza sele wayeka yonke ngocwangcisa zakho zokukhowuda data. Ngenxa yoko, xa athe data counter ezidlulileyo angaziwa. Kuba lula ukusebenza kwawo shaft kufuneka aziswe kwindawo yokuqala. khodi kwandiswe alwa ngokugqibeleleyo kunye umsebenzi yokulinganisa isantya ujikelezo. Esebenzisa ngokubala inani la ukusuka yamanqaku reference kunokuba azichaze njengoko yangoku Inanai elihambiselanayo lika njengokujikeleza engile nto.

encoders ingundoqo

Ngoko-ebizwa ngokupheleleyo isivamvo sikhundla. encoders Ngokwesiqhelo ezinjalo kuvandlakanywa iinkqubo ezintsonkothileyo engaphezulu inkqubela uphawu ngekhompyutha kwaye beesekethe optical. Kodwa banike iinkcukacha into kwangoko emva kokuba elidla efunekayo ukuze nokusebenza ngokuchanekileyo inkqubo xa iyonke. Xa kuthelekiswa nokusetyenziswa kokufundiswa encoders ingundoqo bebenoyilungisa uluhlu olubanzi kakhulu imisebenzi, njengoko imilinganiselo yenziwa usebenzisa yokutshixa ukubetha, kunye neekhowudi ezikhethekileyo digital. Unit isixhobo esifanayo - linani iikhowudi unique digital kweyunithi ojikelezayo (1 turn). Ngenxa yokuba zonke iikhowudi digital sensor output, unique, ukujonga yangoku nokulungelelanisa isindululo yomgama ngoko nangoko emva kokuqinisekiswa kwisixhobo kulula kwaye ngaphandle ilebhile referetnoy. Ngexesha i ikhodi kusebenze amanani kubonakala kwiziphumo womenzi woluvo. Yena luphawu kwindawo yangoku engile ukujikeleza into. Ngoko ke, lo zokukhowuda elipheleleyo alwa nje kuphela ingxaki zokulandela isantya ukujikeleza (ukujikeleza) yenjongosenzi, kodwa avelise iinkcukacha ezichanekileyo malunga nendawo yayo ngqo nangaliphi na ixesha, nokuba enxulumene okanye hayi.

Zezinto encoders ingundoqo

Kuxhomekeka kwiimpawu ezithile ayusolyutnye encoders zisenokwahluka uhlobo nokuqhobosha, okanye ubukho weemfama ngokusebenzisa, okanye eveleleyo shaft vuphukuphuku. Uluhlu izixhobo ezifana nayo zahlukahlukene kakhulu ngokubhekiselele iimpawu zangaphandle: ubude, ububanzi we umzimba njalo njalo. Ukongeza, kwakusazeka ukuba boluvo elililo kwizikhundla umlinganiselo ngexesha ukujikeleza multi-ithuba ne enye ithuba apho. Actuators bavelisa indawo yangoku ngaphakathi turnover enye kwaye abakwaziyo ukuqonda ezininzi nokujikeleziswa eziliqela olongezelelweyo.

khodi Optical - ntoni na?

Le lokuguqulela ke ubeka zixhonywe drive oluthi, ezenziwe ngeglasi. An khodi enombala, ngokuchaseneyo nabenzi boluvo ezichazwe ngasentla, lixhotyiswe ngakumbi ne rastorom kokugcina apho phezu ukujikeleza lihamba shaft kwaye luguqula le torque zibe ukukhanya efunyenwe photosensor kamva.

Olu hlobo converter ibhaqa engile ujikelezo, apho indawo nganye ekhethekileyo lihambisana ikhowudi unique ezizodwa amanani. Yena, kunye nenani revolutions kwaye iyunithi yokulinganisa wexesha elongezelelweyo lomenzi woluvo. Ukuqhagamshela khodi bayo isimiso ukusebenza efanayo kwandiswe nokusebenza ochazwe ngasentla.

Iintlobo abenzi boluvo kuxhomekeke isimiso ukusebenza

Iimpawu encoders zomsebenzi zahlulwe zibe Imagnethi yomhlaba kunye yombane.

Umgaqo ebonakalayo yokusebenza isekelwe ukusetyenziswa wokuqala isiphumo Hall, yafunyanwa ngama E. Hall ngo-1879. Kulo mzekelo, umahluko okunokwenzeka kwenzeka kuphela xa zibekwe wire DC kummandla zibuthe.

Ngeempawu ekusonjululweni kunye ukuchaneka zokukhowuda photoelectric magnethi obuphantsi, kodwa ukusetyenziswa kwayo lula. Yena ongafuni kude izithuba kunye neemeko ezisebenzayo.

Ummeli encoder otsalayo sisixhobo ukuba ukhusela ndzhendzheleko edlula izibonda kazibuthe kwimagnethi rotary, endhawini yo element woluvo. Nkulumo data samaza kwakhona unabo uhlobo ikhowudi yedijithali.

Ifayile ekhowudiweyo photoelectric - uphenyo, ukuba sisebenze ngokususela isivamvo, apho wabona ngenxa yokuba sesichengeni ekukhanyeni ngalo mba. Ivula lo mgaqo-1887 ngu H. Hertz. Xa ukusebenza kolu didi lomenzi woluvo elifana neli inguqu abasisigxina umqadi ukukhanya kube yimitha yombane.

Kuyahambisana photoelectric zokukhowuda optocoupler, woqondo kunye opto-elektroniki. Izivamvo olu hlobo bayawufuna ngakumbi iimpawu lwemveliso, ukusebenza, kunye ngaphezu kwezinye encoders, kodwa oku kufanelekile, kuba isakhono ukuchaneka kwazo iphezulu kakhulu kunaleyo okhuphisana.
