Industrial touch monitors muaj ntau hom kev kov. Cov feem ntau yog capacitive, resistive thiab infrared kov. Txawm li cas los xij, tsis tshua muaj kev paub txog infrared touch monitors. Hnub no kuv yuav muab koj ib qho kev qhia dav dav rau infrared touch monitors. Qhov zoo thiab cov yam ntxwv thiab daim ntawv thov qhov xwm txheej ntawm.
Qhov zoo ntawm lub vijtsam kov infrared yog tias nws tuaj yeem kov nrog ntiv tes, cwj mem, lossis txhua yam khoom uas tuaj yeem thaiv lub teeb. Qhov tsis zoo ntawm lub vijtsam kov infrared yog tias nws tsis hnov zoo thaum siv rau ntawm cov duab kheej kheej. Qhov no yog vim qhov infrared grating matrix uas nyob ntawm kev ua haujlwm pom tseeb yuav tsum nyob rau tib lub dav hlau. Yog li ntawd, lub dav hlau ua hauj lwm uas yeej hnov tsw kov muaj qhov nrug loj dua ntawm qhov screen nkhaus. Qhov chaw, tshwj xeeb tshaj yog nyob rau ntawm cov ces kaum, tab sis qhov tsis txaus no tsis muaj nyob rau ntawm cov vaj huam sib luag tiaj tus, xws li cov kua siv lead ua kua.
Nws tuaj yeem hais tias infrared kov cov ntxaij vab tshaus muaj txiaj ntsig zoo thaum siv ntawm cov vaj huam sib luag tiaj tus. Infrared detection thev naus laus zis tuaj yeem tau txais ib txoj hauv kev yooj yim infrared nrhiav tau los ntawm kev siv infrared emitting raj thiab infrared txais raj (infrared khub raj luv luv) ntawm tib lub wavelength:
Tsuav yog muaj ib qho khoom thaiv qhov kev sib txuas ntawm cov raj infrared, cov teeb liab tau txais yuav poob qis heev. Yog li ntawd, infrared tuaj yeem kuaj xyuas qhov thaiv ntawm cov khoom thiab yog siv dav hauv cov tshuab tiv thaiv tub sab, tsis siv neeg ntsuas tshuab, txee thiab lwm lub tshuab.
Yog hais tias infrared siv nyob rau hauv ib tug luv luv deb, lub degree ntawm thaiv yuav ntes tau raws li lub attenuation ntawm lub teeb liab tau txais. Qhov no yog lub npe hu ua analog. Cov txheej txheem analog siv qhov ntom ntom ntawm cov hlab tau txais qhov kawg thiab tuaj yeem siv rau kev sib piv duab; Txhawm rau tiv thaiv kev cuam tshuam, kev tshawb pom infrared kuj tseem siv tau Pulse txoj kev,
Ntawd yog, lub raj xa hluav taws xob infrared emits lub teeb liab zaus, thiab lub receiver tsuas pom qhov zaus no, thiab hom mem tes muaj peev xwm tiv thaiv kev cuam tshuam. Yog tias hom pulse modulates lub teeb liab ntawm kev ua haujlwm zaus, nws kuj tuaj yeem siv rau kev sib txuas lus digital. Qhov no yog lub npe nrov infrared kev sib txuas lus. Cov chaw taws teeb tswj ntawm cov khoom siv hauv tsev, kev sib txuas lus infrared ntawm cov khoos phis tawj, thiab txawm tias qhov kev sib txuas lus fiber ntau ceev tshaj plaws niaj hnub no yog vim qhov no. Kev sib txuas lus infrared tsis cuam tshuam rau tib neeg lub cev.
