Infrared Data Communications

Infrared cov ntaub ntawv sib txuas lus hais txog kev xa cov ntaub ntawv siv infrared (IR) lub teeb nthwv dej. Qhov kev sib txuas lus wireless no siv cov infrared spectrum, uas nyob dhau qhov pom lub teeb pom kev. Infrared cov ntaub ntawv kev sib txuas lus yog feem ntau ua hauj lwm nyob rau hauv ntau yam kev siv rau luv luv-range wireless cov ntaub ntawv hloov lwm lub tsev. Cov txheej txheem muaj xws li ib tug transmitter uas converts hluav taws xob signals rau hauv infrared lub teeb pulses. Cov pulses nqa cov ntaub ntawv encoded thiab kis tau los ntawm qhov chaw dawb mus rau tus txais. Tus receiver ces txiav txim siab cov teeb liab infrared rov qab rau hauv cov thawj hluav taws xob teeb liab, tso cai rau rov qab tau cov ntaub ntawv xa mus. Kev sib txuas lus cov ntaub ntawv infrared muaj ntau qhov zoo, nrog rau kev yooj yim, kev siv hluav taws xob tsawg, thiab kev siv nyiaj tsawg. Nws feem ntau yog siv hauv cov chaw taws teeb tswj, qhov twg cov teeb liab infrared los ntawm cov chaw taws teeb tswj tau siv los tswj cov khoom siv hluav taws xob xws li TV, cua txias, thiab lub tshuab suab.
