2. Kev tshaj tawm ntau zaus: Lub sijhawm xa tuaj tuaj yeem tsim lossis hloov pauv los ntawm lub platform, thiab lub sijhawm tshaj tawm tsawg kawg yog txhua teev
3. Kev sau cov ntaub ntawv hnyav: 4 teev los ntawm lub sijhawm pib, ib qho taw qhia txhua 5 feeb, tag nrho ntawm 48 cov ntsiab lus ntawm cov dej ntws.
4. Cov ntaub ntawv rov ntim dua: Thaum kev tshaj tawm cov ntaub ntawv tsis ua tiav, cov ntaub ntawv yuav raug xa rov qab xa rov qab nyob rau lub sijhawm tshaj tawm tom ntej, thiab cov ntaub ntawv nyob rau hauv qhov chaw khaws cia tau zoo tuaj yeem rov qhia dua.
5. Kev teeb tsa tsis tu ncua: Discrete lub sij hawm qhia cov ntsiab lus randomly los ntawm qhov kev pab cuam, qhov tsawg kawg nkaus kwv yees ntev yog 10S, thiab lub neej ntawd yog 0 mus rau 8 cov ntsiab lus los xyuas kom meej tias cov ntaub ntawv loj nyob rau hauv ib lub sij hawm luv luv yuav tsis thaiv qhov chaw nres tsheb sib txuas lus.
6. Chaw taws teeb ntawm qhov tsis sib xws: Los ntawm qhov ze-kawg handheld infrared nyeem ntawv thiab
Kev sib txuas lus nrog kev tswj hwm platform, teeb tsa IP, chaw nres nkoj, thiab lwm yam
7. Tswb muaj nuj nqi: Thaum lub roj teeb undervoltage qis dua tus nqi predetermined, lub platform yuav cia li tswb ceeb toom rau tus thawj tswj
8. Lub Sijhawm proofreading: Thaum cov ntaub ntawv raug tshaj tawm ib ntus, lub moos yuav tau txais kev lees paub nrog lub platform kom paub tseeb tias qhov tseeb ntawm lub sijhawm.
