Anthu ambiri amakhulupirira kuti mota ndiye maziko okhawo mu dongosolo lowongolera kuyenda. Komabe, mu zaka zanga zambiri zogwirira ntchito ndi makina oyendetsera ang'onoang'ono, ndazindikira kuti nzeru zenizeni - kuthekera kokwaniritsa ndikusunga ulamuliro wolondola - zili ndi encoder yokha. Ngati mulibe njira yowunikira yofunikira iyi, mota ndi wovuta kwambiri. Izi ndizofunikira kwambiri kwama mota a magiya ang'onoang'onochifukwa kulekerera kwawo zolakwika kumakhala kochepa kwambiri. Kusankha encoder yoyenera si vuto laukadaulo lokha, komanso ndi malire pa kudalirika kwa malonda onse ndi magwiridwe antchito a chisankho chofunikira.

Chifukwa chiyani ma Encoders ndi "ubongo" wa ma DC Gear Motors ang'onoang'ono

Kuphatikiza kwa encoder ndimota yaying'ono yamagetsi ya DCndi zofanana ndi kusintha magetsi osavuta kukhala makina owongolera otsekedwa. Cholembera chopereka deta yofunikira, monga malo, liwiro ndi njira zimapangitsa kuti chowongolera chizitha kusintha nthawi yeniyeni. Izi ndizofunikira kwambiri pakugwiritsa ntchito komwe kumafuna kulondola kwambiri. Mwachitsanzo, taganizirani zida zamankhwala zonyamulika - mota yaying'ono yogwiritsidwa ntchito pazifukwa zachipatala - malo enieni otumizira madzi kapena za chitetezo cha wodwala. Cholembera chimatsimikizira kuti kutulutsa kwa mota, ngakhale mutachepetsa zida, kukugwirizana kwathunthu ndi zofunikira za makina.

Vuto la kuthetsa vutoli: Zambiri sizili bwino nthawi zonse

Mainjiniya nthawi zambiri amalakwitsa kuganiza kuti njira yabwino kwambiri yopangira zinthu (pulses per revolution, PPR) nthawi zonse ndiyo yabwino kwambiri. Ngakhale kuti ndi zoona kuti njira yabwino kwambiri yopangira zinthu imapereka ulamuliro wabwino, komanso imawonjezera zovuta komanso mtengo.

• Mtengo weniweni wa PPRS wokwera:

Kuchuluka kwa mphamvu kumatanthauza kuti wowongolera amafunika kukonza ma signal mwachangu. Kuchedwa ndi zolakwika zitha kuchitika ngati wowongolerayo sangathe kutsatira ma pulse frequency. Kuphatikiza apo, kutsika kwa shaft yotulutsa kwasinthidwa kwambiri kuti pakhale ma gear ratio apamwamba a 12V micro gear motors. Tiyenera kudzifunsa tokha: kodi mtengo wowonjezera ndi zovuta za ma encoder a 1024 PPR ndizofunikiradi pamene 256 PPR encoder ikhoza kukwaniritsa zofunikira zenizeni za pulogalamuyo?

• Malangizo othandiza:

Malangizo anga ndi akuti choyamba muwerengere kulondola kwa malo komwe kumafunika pa shaft yomaliza yotulutsa kenako mugwiritse ntchito mobwerera m'mbuyo. Pa ntchito zambiri za ogula, komanso ntchito zambiri zamafakitale, kutsimikiza kokhazikika komanso koyenera nthawi zambiri kumakhala kwanzeru komanso kotsika mtengo.

Ma encoders a kuwala ndi maginito: Zinthu zachilengedwe

Kusankha chojambulira cha kuwala kapena cha maginito kumadalira kwambiri malo ogwirira ntchito kwa injini osati momwe imagwirira ntchito.

• Kuzindikira kwa kuwala: Ma encoder owoneka ndi olondola kwambiri ndipo amagwiritsa ntchito kuwala powerenga diski yolembera. Komabe, ndi osavuta kumva fumbi, chinyezi komanso kusinthasintha kwakukulu kwa kutentha. Ngati ntchito yanu ili pamalo ovuta - monga makina ogulitsa kapena sensa yakunja - ingayambitse kulephera msanga. Kukhazikika kwa encoder ya maginito: werengani diski ya maginito, encoder ya maginito pogwiritsa ntchito masensa a hall effect ndi "chinthu chofunikira kwambiri" mumakampani. Za kuipitsa ndi kukana kugwedezeka ndizabwino kwambiri kuposa encoder yowonera. Ngakhale kuti ikhoza kukhala yolondola pang'ono kuposa ma encoder owonera, kudalirika kwawo m'malo ovuta kumawapangitsa kukhala abwino kwambiri pakugwiritsa ntchito monga makina agalimoto kapena makina odziyimira pawokha amakampani.

Lingaliro la Pincheng: kuphatikiza ndi kusintha

• Kupatula buku la deta: Sitimangogulitsa zinthu zokha, koma timapanga mayankho. Kasitomala akabwera kudzafunsa za injini ya microgear ya chinthu chatsopano, timasanthula dongosolo lonse - kuphatikizapo katundu, nthawi yogwirira ntchito, ndi momwe chilengedwe chilili - tisanapereke encoder yoyenera. Izi zimatsimikizira kuti kulumikizana kwa makina kopanda cholakwika, mawonekedwe amagetsi ndi omveka bwino, ndipo dongosolo lomaliza limatha kugwira ntchito mokwanira monga momwe timayembekezera.

• Ubwino wosintha: Pazofunikira zapadera, monga ma mota a microgear azachipatala omwe amafunikira PPR yosakhala yokhazikika kapena ma signal apadera otulutsa, timatha kusintha mawonekedwe a encoder mwachindunji mufakitale, kupulumutsa makasitomala nthawi yambiri ndikuchepetsa chiopsezo cha zolakwika zophatikiza. Izi ndizofunikira kwambiri pazida zomwe zimafuna kugwiritsidwa ntchito kodalirika kwa nthawi yayitali popanda kukonza.

Pamapeto pake, kuti musankhe yoyeneramota yamagetsi ya DCChojambulira ndi chisankho chanzeru, chomwe chikufunika kuti pakhale mgwirizano pakati pa zofunikira zaukadaulo ndi zofunikira zenizeni zogwiritsira ntchito.

Muyenera kusankha izi ndi mnzanu amene amamvetsetsa bwino za kayendedwe kakang'ono. Mwa kuyang'ana kwambiri pa zosowa zenizeni za pulogalamu yanu, osati chiwerengero chachikulu kwambiri mu pepala la deta, mutha kuwonetsetsa kuti malonda akhala nthawi yayitali komanso olondola. Sankhani ogwirizana nawo angapereke mayankho ogwirizana komanso odalirika.
