Txawm hais tias muaj kev txhim kho sai ntawm cov khoom siv ntse xws li xov tooj ntawm tes, TV tseem yog ib qho khoom siv hluav taws xob tsim nyog rau tsev neeg, thiab cov chaw taws teeb tswj, raws li cov khoom siv tswj hwm ntawm TV, tso cai rau tib neeg los hloov TV raws yam tsis muaj teeb meem.
Txawm hais tias kev loj hlob sai ntawm cov khoom siv ntse xws li xov tooj ntawm tes, TV tseem yog cov khoom siv hluav taws xob tsim nyog rau tsev neeg.Raws li cov cuab yeej tswj hwm ntawm TV, tib neeg tuaj yeem hloov tau yooj yim TV raws.Yog li yuav ua li cas cov chaw taws teeb tswj kom paub txog cov chaw taws teeb tswj ntawm TV?
Nrog rau kev nce qib ntawm thev naus laus zis, hom kev tswj chaw taws teeb wireless tseem nce ntxiv.Feem ntau muaj ob hom, ib qho yog infrared chaw taws teeb tswj, lwm yam yog xov tooj cua co tswj hom.Nyob rau hauv peb lub neej niaj hnub, feem ntau siv dav yog infrared chaw taws teeb tswj hom.Ua piv txwv TV chaw taws teeb tswj, cia peb tham txog nws txoj haujlwm ua haujlwm.
Cov chaw taws teeb tswj feem ntau yog tsim los ntawm kev xa xov hluav taws xob (chaw taws teeb controller), receiver thiab central processing unit (CPU), uas lub receiver thiab CPU nyob hauv TV.Cov chaw taws teeb tswj TV dav dav siv cov kab hluav taws xob infrared nrog lub wavelength ntawm 0.76 ~ 1.5 microns los tawm cov ntaub ntawv tswj.Nws qhov kev ua haujlwm nrug tsuas yog 0 ~ 6 meters thiab nthuav tawm raws txoj kab ncaj nraim.Nyob rau hauv lub internal Circuit Court ntawm lub chaw taws teeb controller, sib haum mus rau txhua tus yuam sij ntawm lub chaw taws teeb controller, lub internal Circuit Court txais ib tug tshwj xeeb coding txoj kev coj mus rau nws.Thaum tus yuam sij tshwj xeeb raug nias, ib qho kev sib txuas hauv Circuit Court yog txuas nrog, thiab lub nti tuaj yeem tshawb xyuas qhov Circuit Court txuas thiab txiav txim siab qhov tseem ceeb yog nias.Tom qab ntawd, lub nti yuav xa tawm cov coding ib ntus teeb liab sib raug rau tus yuam sij.Tom qab amplification thiab modulation, lub teeb liab yuav raug xa mus rau lub teeb-emitting diode thiab hloov mus rau hauv infrared teeb liab mus rau sab nraud.Tom qab tau txais lub teeb liab infrared, lub TV receiver demodulates thiab ua kom nws rov qab tswj lub teeb liab, thiab xa cov teeb liab mus rau lub hauv paus ua haujlwm, uas ua haujlwm sib xws xws li hloov cov channel.Yog li, peb paub qhov chaw taws teeb tswj kev ua haujlwm ntawm TV.
Infrared chaw taws teeb tswj muaj ntau yam zoo.Ua ntej tshaj plaws, tus nqi ntawm infrared chaw taws teeb tswj yog qis dua thiab yooj yim dua kom tau txais los ntawm pej xeem.Qhov thib ob, cov chaw taws teeb tswj infrared yuav tsis cuam tshuam rau ib puag ncig ib puag ncig thiab yuav tsis cuam tshuam nrog lwm yam khoom siv hluav taws xob.Txawm hais tias cov khoom siv hauv tsev hauv cov tsev sib txawv, peb tuaj yeem siv tib hom kev tswj chaw taws teeb, vim tias cov chaw taws teeb tswj infrared tsis tuaj yeem nkag mus rau phab ntsa, yog li yuav tsis muaj kev cuam tshuam.Thaum kawg, cov chaw taws teeb tswj qhov system Circuit Court debugging yog qhov yooj yim, feem ntau peb tuaj yeem siv nws yam tsis muaj kev debugging, tsuav yog peb txuas kom raug raws li qhov teev hauv Circuit Court.Yog li ntawd, infrared chaw taws teeb tswj tau siv dav hauv peb cov khoom siv hauv tsev.
Nrog rau qhov tshwm sim ntawm lub sijhawm ntse, cov haujlwm ntawm TV tau dhau los ua ntau thiab ntau haiv neeg, tab sis cov chaw taws teeb tswj tau dhau los ua ntau thiab yooj yim.Tsis muaj ntau cov nyees khawm ua ntej, thiab cov tsos yog ntau humanized.Txawm li cas los xij, txawm li cas los xij, nws yuav txhim kho li cas, cov chaw taws teeb tswj, uas yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob rau tib neeg-khoos phis tawj, yuav tsum hloov tsis tau.
