Infrared photoelectric keyboards tuaj yeem siv rau hauv ntau cov ntawv thov. Thaum siv lub tshuab txais hluav taws xob infrared photoelectric, yuav tsum tau them nyiaj rau ib puag ncig kev mob thiaj li ua rau infrared photoelectric keyboards tuaj yeem ua haujlwm nquag thiab muaj kev ntseeg siab. Infrared photoelectric keyboards feem ntau ua haujlwm stably thaum lub ambient illuminance siab. Txawm li cas los xij, nws yuav tsum zam tias qhov hloov kho qhov sib txig ntawm lub sensor ntsib lub teeb pom kev muaj zog xws li lub hnub ci thiab lub teeb ua pa. Feem ntau siv infrared photoelectric hloov kev faib tawm txoj kev: Raws li txoj kev kuaj pom, nws tuaj yeem muab faib ua peb hom: reflection type, opposite beam hom thiab specular reflection type. Qhov kev sib nrug ntawm lub nqaj-txav pom kev deb yog ntev thiab tuaj yeem ntes tus ceev (transmittance) ntawm cov khoom translucent. Kev cuam tshuam kev ua haujlwm nyob deb yog txwv nyob ze ntawm kev sib tshuam ntawm kab teeb thiaj zam tau cov teebmeem tom qab. Daim iav tsom iav hom muaj qhov cuam tshuam ntev dua, tsim nyog rau kev paub txog lub sijhawm ntev, thiab tseem tuaj yeem pom cov khoom pob tshab lossis ib nrab.
kev faib tawm
Raug cais los ntawm kev teeb tsa
Infrared photoelectric keyboards tuaj yeem muab faib ua peb hom raws li tus qauv: cais cov tso suab, tsim lub suab thiab tsim ua lub zog txhawb.
Lub suab yam sib xyaw ua ke yog cais cov amplifier thiab lub suab, thiab siv cov hluav taws xob sib xyaw tshwj xeeb thiab cov khoom siv sib xyaw ua ke kom ua, vim tias lub sensor muaj cov yam ntxwv ntawm ultra-me thiab ntau hom, thiab cov amplifier muaj ntau txoj haujlwm. Yog li no, hom no adopts lub davhlau ya nyob twg thaiv kev sib txuas txoj kev thiab tuaj yeem siv rau ob qho tib si AC thiab DC cov khoom siv fais fab. Nws muaj qhov ua haujlwm ntawm ntawm thiab tawm qeeb, tuaj yeem tsim lub teeb thiab lub suab hloov, tuaj yeem tswj tau 6 hom khoom tsim tawm, thiab muaj ob hom kev tawm suab ntawm kev sib tiv tauj thiab qib.
Lub tshuab ua kom nrov zog yog lub zog txuas ntxiv thiab lub zog tsim, ua nrog ASIC thiab nto saum toj tshuab, thiab ua haujlwm nrog DC fais fab mov. Nws teb tau qhov xwm txheej ceev (muaj ob yam ntawm 0.1ms thiab 1ms), tuaj yeem kuaj pom cov khoom me me thiab siab ceev txav. Hloov pauv qhov polarity ntawm lub zog mov tuaj yeem hloov ntawm qhov kev hloov qaim thiab tsaus, thiab tuaj yeem tsim qhov ntsuas tus kheej ntsuas kev ua haujlwm ruaj khov ua haujlwm qhov ntsuas pom. Ob qhov voltage thiab tawm cov qauv tam sim no tuaj yeem tiv thaiv kev cuam tshuam, uas yooj yim heev hauv kev teeb tsa.
Chav tsev tsim hluav taws xob ua ke ua ke nrog lub tshuab ntsuas suab, lub zog thiab lub zog siv hluav taws xob, thiab tau tsim nrog kev mob siab rau txoj kev sib txuas ua ke thiab saum npoo av thev naus laus zis. Nws feem ntau siv AC fais fab, uas yog haum rau hloov chaw sib cuag hom kev hloov mus rau ntawm qhov chaw ntau lawm thiab tuaj yeem siv ncaj qha rau lub zog tswj tam sim no. Koj tuaj yeem tuaj yeem teeb tsa tus kheej-tshawb nrhiav kev ua haujlwm ruaj khov qhov chaw ua haujlwm qhov taw qhia teeb los ntawm koj tus kheej. Cov khoom tso tawm yog nruab nrog SSR cov khoom khov kho lub xeev rov qab los yog xa tawm ib txwm qhib thiab ib txwm kaw kev sib chwv, uas tuaj yeem tiv thaiv kev cuam tshuam kev sib txuam thiab tuaj yeem ntsia nruj me ntsis hauv cov kab ke.
Nta
1. Qhov tshwj xeeb kev ntsuas tus kheej thiab qhov chaw ua haujlwm thaj chaw muaj kev tiv thaiv kev ua haujlwm tuaj yeem paub hauv lub sijhawm seb puas ua haujlwm tau ntseeg tau.
2. Tawm tsam, rov tsom iav, thiab tsom iav tsom iav cov yees duab tsom iav txhua tus muaj qhov cuam tshuam ntawm kev tiv thaiv kev cuam tshuam thiab yooj yim rau nruab.
3. Cov lus teb ceev nrawm dua, cov lus teb ceev ntawm lub tshuab hluav taws xob high-speed photoelectric tuaj yeem ncav cuag 0.1ms, 300,000 kev kuaj pom ua haujlwm tuaj yeem ua ib feeb, thiab cov khoom me me txav ntawm kev kub ceev tuaj yeem kuaj tau.
4. Txais cov kab ke sib xyaw tshwj xeeb thiab siab tshaj SMT nto saum toj tshuab, qhov kev cia siab yog siab heev.
5. Kev ntsuas me me, lub teeb yuag, kev teeb tsa yooj yim thiab kev debugging, thiab kev tiv thaiv luv luv.
