Feem ntau ntseeg tias lub cev muaj zog yog tib lub hauv paus hauv lub kaw lus tswj kev txav mus los. Txawm li cas los xij, los ntawm kuv ntau xyoo ntawm kev ua haujlwm nrog cov tshuab tsav me me, kuv tau paub tias kev txawj ntse tiag tiag - lub peev xwm ua tiav thiab tswj hwm qhov tseeb - nyob ntawm lub encoder tag nrho. Yog tias koj tsis muaj lub voj voog tseem ceeb no, lub cev muaj zog zoo li ntxhw. Qhov no tseem ceeb heev raumicro iav motorsvim lawv qhov kev ua yuam kev tsis zoo yog qhov tsawg heev. Kev xaiv tus encoder tsim nyog tsis yog tsuas yog teeb meem kev siv tshuab xwb, nws yog qhov txwv rau tag nrho cov khoom kev ntseeg siab thiab kev ua tau zoo ntawm kev txiav txim siab tseem ceeb.

Vim li cas Encoders yog "lub hlwb" ntawm cov DC Gear Motors me me

Kev sib xyaw ua ke ntawm tus encoder nrog ib qholub cev muaj zog me me DC iavzoo ib yam li kev hloov pauv lub zog fais fab yooj yim mus rau hauv lub kaw lus tswj hwm kaw-voj. Lub encoder los muab cov ntaub ntawv tsim nyog, xws li txoj haujlwm, qhov ceev thiab kev taw qhia ua rau tus maub los tuaj yeem hloov kho lub sijhawm tiag tiag. Qhov no yog qhov tseem ceeb rau cov ntawv thov uas xav tau qhov tseeb siab. Piv txwv li, xav txog cov khoom siv kho mob portable - micro iav motor siv rau kev kho mob - qhov chaw tseeb ntawm cov kua xa mus lossis txog kev nyab xeeb ntawm tus neeg mob. Lub encoder ua kom ntseeg tau tias cov zis ntawm lub cev muaj zog, txawm tias tom qab txo iav, ua raws li qhov yuav tsum tau ua ntawm lub kaw lus.

Kev daws teeb meem ntawm qhov teeb meem: Ntau dua tsis yog qhov zoo dua tas li

Cov kws ua vaj tse feem ntau poob rau hauv qhov yuam kev ntawm kev xav tias qhov kev daws teeb meem siab tshaj plaws (pulses per revolution, PPR) yeej ib txwm yog qhov kev xaiv zoo tshaj plaws. Txawm hais tias nws yog qhov tseeb tias qhov kev daws teeb meem siab muab kev tswj hwm zoo dua, tab sis kuj ua rau qhov nyuaj thiab tus nqi nce ntxiv.

• Tus nqi tiag tiag ntawm PPRS siab:

Kev daws teeb meem siab dua txhais tau tias tus maub los xav tau kev ua cov teeb liab sai dua. Kev qeeb thiab qhov yuam kev tuaj yeem tshwm sim yog tias lub microcontroller tsis tuaj yeem ua raws li qhov zaus ntawm lub zog. Tsis tas li ntawd, qhov kev daws teeb meem ntawm cov zis tawm tau zoo dua rau cov iav loj 12V micro iav motors. Peb yuav tsum nug peb tus kheej: puas yog tus nqi ntxiv thiab qhov nyuaj ntawm 1024 PPR encoders tsim nyog tiag tiag thaum 256 PPR encoder tuaj yeem ua tau raws li qhov xav tau tiag tiag ntawm daim ntawv thov?

• Cov lus qhia siv tau:

Kuv cov lus qhia yog ua ntej xam qhov tseeb ntawm qhov chaw uas xav tau rau qhov kawg ntawm lub qhov tso zis thiab tom qab ntawd ua haujlwm rov qab. Rau feem ntau ntawm cov neeg siv khoom siv, thiab txawm tias ntau daim ntawv thov kev lag luam, qhov kev daws teeb meem nruab nrab thiab ruaj khov feem ntau yog qhov kev xaiv ntse dua thiab pheej yig dua.

Cov encoders optical thiab magnetic: Cov yam ntxwv ib puag ncig

Qhov kev xaiv ntawm optical lossis magnetic encoder nyob ntawm ntau dua ntawm qhov chaw ua haujlwm ntawm lub cev muaj zog dua li ntawm kev ua tau zoo.

• Kev rhiab heev ntawm qhov muag: Cov encoders optical yog qhov tseeb heev thiab siv lub teeb los nyeem cov coding disk. Txawm li cas los xij, lawv yog qhov rhiab heev rau hmoov av, dej noo thiab qhov kub thiab txias hloov pauv. Yog tias koj daim ntawv thov nyob rau hauv ib puag ncig hnyav - xws li lub tshuab muag khoom lossis sab nraum zoov sensor - nws tuaj yeem ua rau tsis ua haujlwm ua ntej. Kev ruaj khov ntawm lub magnetic encoder: nyeem cov magnetic disk, magnetic encoder siv hall effect sensors yog "mainstay" hauv kev lag luam. Ntawm cov pa phem thiab kev co tsis kam yog zoo dua li lub optical encoder. Txawm hais tias lawv yuav tsis raug me ntsis dua li optical encoders, lawv qhov kev ntseeg tau hauv ib puag ncig hnyav ua rau lawv zoo tagnrho rau cov ntawv thov xws li automotive systems lossis industrial automation.

Lub tswv yim Pincheng: kev koom ua ke thiab kev hloov kho

• Tshaj li phau ntawv cov ntaub ntawv: Peb tsis yog tsuas yog muag cov khoom xwb, peb tsim cov kev daws teeb meem. Thaum tus neeg siv khoom tuaj nug txog lub cev muaj zog microgear rau cov khoom tshiab, peb tshuaj xyuas tag nrho lub kaw lus - suav nrog qhov hnyav, lub voj voog ua haujlwm thiab cov xwm txheej ib puag ncig - ua ntej pom zoo rau lub encoder zoo. Qhov no ua kom ntseeg tau tias qhov kev sib txuas ua ke zoo meej, qhov sib txuas hluav taws xob meej thiab raug, qhov kawg tuaj yeem khiav tau raws li qhov xav tau.

• Cov txiaj ntsig ntawm kev hloov kho: Rau cov kev xav tau tshwj xeeb, xws li cov cav microgear kho mob uas xav tau cov PPR tsis yog tus qauv lossis cov teeb liab tshwj xeeb, peb tuaj yeem hloov kho qhov encoder interface ncaj qha hauv lub Hoobkas, txuag cov neeg siv khoom lub sijhawm tseem ceeb thiab txo qhov kev pheej hmoo ntawm kev ua yuam kev sib koom ua ke. Qhov no tseem ceeb heev rau cov khoom siv uas xav tau kev ua haujlwm ntev ntev yam tsis tas yuav saib xyuas.

Thaum kawg, rau koj xaiv qhov tsim nyogdc iav tsavencoder yog qhov kev txiav txim siab zoo, xav tau kom ua tiav qhov sib npaug ntawm cov lus qhia txog kev siv tshuab thiab cov kev xav tau tiag tiag.

Koj yuav tsum xaiv qhov no nrog tus khub uas nkag siab txog qhov sib txawv ntawm kev tswj kev txav me me. Los ntawm kev tsom mus rau qhov xav tau tiag tiag ntawm koj daim ntawv thov, tsis yog tsuas yog tus lej siab tshaj plaws hauv daim ntawv qhia cov ntaub ntawv, koj tuaj yeem ua kom cov khoom siv tau ntev thiab raug. Xaiv cov khub tuaj yeem muab cov kev daws teeb meem sib xyaw thiab txhim khu kev qha.
