Yas khau npog tshuab yog lub tshuab tshwj xeeb hauv kev tsim cov khau yas. Cov khoom siv PE yog cov cuab yeej siv hluav taws xob uas tuaj yeem ua tiav cov kab ntau lawm los ntawm cov khoom siv raw mus rau cov khoom tiav. Cov kev tswj hluav taws xob siab tshaj plaws suav nrog kev ua haujlwm zaus sib txawv, photoelectric detector thiab tsis siv neeg kaw. Vuam txais kev sib xyaw ua ke ntawm kev kho cua sov vuam. Cov pwm tuaj yeem hloov tau los tsim cov khoom ntawm ntau yam kev qhia tshwj xeeb. Muaj peev xwm tsim PE thiab CPE khau npog. Yas khau npog tshuab muaj qhov zoo ntawm cov khoom zoo, tus nqi qis thiab cov zis siab. Nws tuaj yeem hloov cov khau npog phau ntawv, txuag kev ua haujlwm thiab txo cov nqi. tuaj yeem kho raws li cov neeg siv khoom xav tau.
Cov yam ntxwv ntawm kev ua tau zoo ntawm cov yas khau npog tshuab:
1. Siv zaus converter los tswj kev ua haujlwm;
2. Nws siv cov khoom zoo thiab muab kev ua haujlwm ruaj khov;
3. Tsis siv neeg tswj qhov kub thiab txias.
4. Suav thiab Askiv ua haujlwm interface, khawm tswj vaj huam sib luag, yooj yim kawm;
5. Los ntawm cov khoom siv raw khoom mus rau cov khoom txheej, cov khoom suav yog ua tiav tag nrho. Los ntawm pub rau cov khoom tiav, tag nrho cov txheej txheem kev ua haujlwm tsis siv neeg xav tau ib tus neeg.
