1, encoder ndi chiyani
Panthawi yogwira ntchito aWorm gearbox N20 DC mota, magawo monga apano, kuthamanga ndi malo achibale amayendedwe ozungulira a shaft yozungulira amayang'aniridwa munthawi yeniyeni kuti adziwe momwe thupi lagalimoto lilili ndi zida zomwe zimakokedwa, komanso kuwongolera momwe ma mota amagwirira ntchito ndi zida munthawi yeniyeni, potero kuzindikira ntchito zambiri zapadera monga servo ndi kuwongolera liwiro. Apa, kugwiritsa ntchito encoder ngati choyezera chakutsogolo sikumangofewetsa njira yoyezera, komanso yolondola, yodalirika komanso yamphamvu. Encoder ndi sensa yozungulira yomwe imatembenuza kuchuluka kwa thupi la malo ndi kusuntha kwa magawo ozungulira kukhala mndandanda wa zizindikiro zamtundu wa digito, zomwe zimasonkhanitsidwa ndikusinthidwa ndi dongosolo lolamulira kuti lipereke malamulo angapo kuti asinthe ndikusintha momwe ntchito ya zipangizo. Ngati encoder ikuphatikizidwa ndi giya kapena screw screw, itha kugwiritsidwanso ntchito kuyeza malo ndi kusamuka kwa mizere yosuntha.
2, gulu la encoder
Gulu loyambira la encoder:
Encoder ndi makina osakanikirana ndi magetsi osakanikirana a chipangizo choyezera molondola, chizindikiro kapena deta idzasungidwa, kutembenuka, kulankhulana, kutumiza ndi kusunga deta ya chizindikiro. Kutengera ndi mawonekedwe osiyanasiyana, ma encoders amagawidwa motere:
● Code disc ndi sikelo ya code. Encoder yomwe imasintha kusamuka kwa mzere kukhala siginecha yamagetsi imatchedwa code scale, ndipo yomwe imasintha kusamuka kwa angular kukhala telecommunication ndi code disc.
● Ma encoder owonjezera. Amapereka zambiri monga malo, ngodya ndi kuchuluka kwa matembenuzidwe, ndikutanthauzira mulingo wotsatira ndi kuchuluka kwa kugunda kulikonse.
● Encoder wathunthu. Amapereka zidziwitso monga malo, ngodya, ndi kuchuluka kwa matembenuzidwe muzowonjezera zamakona, ndipo kuwonjezereka kulikonse kwa angular kumapatsidwa code yapadera.
● encoder ya Hybrid absolute. Encoder ya hybrid absolute encoder imatulutsa zidziwitso ziwiri: gulu limodzi lazidziwitso limagwiritsidwa ntchito kuzindikira malo omwe ali ndi chidziwitso chonse, ndipo seti inayo ndi yofanana ndendende ndi zomwe zimachokera ku encoder yowonjezereka.
Ma encoder omwe amagwiritsidwa ntchito kwambiri pama motors:
●Ma encoder owonjezera
Mwachindunji ntchito photoelectric kutembenuka mfundo linanena bungwe la magawo atatu lalikulu yoweyula pulses A, B ndi Z. Kusiyana kwa gawo pakati pa seti ziwiri za zimachitika A ndi B ndi 90o, kuti malangizo kasinthasintha akhoza kuweruzidwa mosavuta; gawo la Z ndi kugunda kumodzi pakusintha kulikonse ndipo amagwiritsidwa ntchito poyika malo. Ubwino: Kumanga mfundo zosavuta, moyo wamakina wapakati ukhoza kupitilira maola masauzande ambiri, kuthekera kolimba kotsutsana ndi kusokoneza, kudalirika kwakukulu, komanso koyenera kufalitsa mtunda wautali. Zoyipa: kulephera kutulutsa chidziwitso chonse cha malo ozungulira shaft.
● Encoder wathunthu
Pali njira zingapo zotsatsira ma code panjira yozungulira pagawo lozungulira la sensa, ndipo njira iliyonse imapangidwa ndi magawo otumiza kuwala komanso osatulutsa kuwala, ndipo kuchuluka kwa magawo amayendedwe oyandikana nawo kumawirikiza kawiri, ndipo kuchuluka kwa ma code pa code plate ndi nambala ya manambala a binary. Pamene code plate ili m'malo osiyanasiyana, chinthu chilichonse chazithunzi chimasinthidwa kukhala chizindikiro chofananira molingana ndi kuwala kapena ayi, kupanga nambala ya binary.
Mtundu uwu wa encoder umadziwika kuti palibe chowerengera chomwe chimafunikira ndipo khodi ya digito yokhazikika yogwirizana ndi malowa imatha kuwerengedwa pamalo aliwonse a mayendedwe ozungulira. Mwachiwonekere, ma tchanelo ochulukirachulukira, ndiye kuti chiwongolero chake ndi chapamwamba, komanso kwa encoder yokhala ndi N-bit binary resolution, code disk iyenera kukhala ndi njira za N code. Pakadali pano, ku China kuli zinthu za 16-bit absolute encoder.
3, mfundo ntchito encoder
Ndi disk photoelectric code yokhala ndi olamulira pakati, pali chiphaso chozungulira ndi mizere yolemba mdima pa iyo, ndipo pali photoelectric kutumiza ndi kulandira zipangizo kuwerenga izo, ndipo magulu anayi a sine wave zizindikiro zimaphatikizidwa mu A, B, C ndi D. Sine wave amasiyana ndi 90 madigiri kusiyana (360 madigiri okhudzana ndi circumferential mafunde ozungulira ndi mafunde apamwamba ndi B, ndi gawo B akhoza reposed ndi A, B, C ndi D. onjezerani chizindikiro chokhazikika; ndipo kugunda kwina kwa gawo la Z kumatuluka pakusintha kulikonse kuyimira ziro malo.
Popeza magawo awiriwa A ndi B ali osiyana ndi madigiri 90, akhoza kufananizidwa ngati gawo A lili kutsogolo kapena gawo B lili kutsogolo kuti lizindikire kuzungulira ndi kubweza kwa encoder, ndipo ziro zolozera pang'ono za encoder zitha kupezedwa kudzera pa zero pulse. Encoder code mbale zipangizo ndi galasi, zitsulo, pulasitiki, galasi code mbale waikidwa pa galasi woonda kwambiri lolembedwa mzere, kukhazikika kwake matenthedwe ndi zabwino, mwatsatanetsatane mkulu, zitsulo code mbale mwachindunji kudutsa osati lolembedwa mzere, osati osalimba, koma chifukwa chitsulo ali makulidwe ena, kulondola ndi malire, matenthedwe bata ndi dongosolo la kukula kwake ndi otsika mtengo kuposa galasi, pulasitiki mtengo wake ndi otsika mtengo, galasi, pulasitiki, mtengo wake ndi otsika mtengo kuposa galasi, pulasitiki. kutentha bata, moyo ndi osauka Ena.
Resolution - encoder kuti apereke mizere ingati yodutsa kapena yakuda pamadigiri 360 a kuzungulira imatchedwa kusamvana, komwe kumadziwikanso kuti kusamvana, kapena mizere ingati, nthawi zambiri mu mizere 5 ~ 10000 pakusintha kosintha.
4, Muyeso wa malo ndi mfundo yowongolera mayankho
Ma encoder amakhala ndi malo ofunikira kwambiri pama elevator, zida zamakina, kukonza zinthu, makina oyankha pamagalimoto, komanso pakuyezera ndi kuwongolera zida. Encoder amagwiritsa ntchito grating ndi gwero la kuwala kwa infrared kuti asinthe chizindikiro cha kuwala kukhala chizindikiro chamagetsi cha TTL (HTL) kudzera pa wolandila. Mwa kusanthula pafupipafupi mlingo wa TTL ndi kuchuluka kwa milingo yayikulu, mawonekedwe ozungulira ndi malo ozungulira agalimoto amawonekera.
Popeza ngodya ndi malo akhoza kuyeza molondola, encoder ndi inverter akhoza kupangidwa kukhala otsekedwa-loop control system kuti ulamuliro ukhale wolondola, chifukwa chake zikepe, zida zamakina, ndi zina zotero zingagwiritsidwe ntchito molondola.
5, Mwachidule
Mwachidule, timamvetsetsa kuti ma encoders amagawidwa kukhala owonjezera komanso mtheradi molingana ndi kapangidwe kawo, ndipo onsewo amasintha ma signature ena, monga ma sign optical, kukhala ma sign amagetsi omwe amatha kusanthula ndikuwongolera. Ma elevator wamba ndi zida zamakina m'miyoyo yathu zimachitika kutengera kusintha kolondola kwa mota, ndipo kudzera mumayendedwe otsekeka amtundu wamagetsi, encoder yokhala ndi inverter ndi njira yachilengedwe yopezera kuwongolera kolondola.
