NB-IoT muaj nuj nqi
Kov khawm: Nws tuaj yeem siv rau kev saib xyuas ze ze, thiab tuaj yeem ua rau NB qhia.Nws siv txoj kev kov capacitive, qhov kov rhiab heev.
Kev txij nkawm nyob ze: nws tuaj yeem siv rau kev saib xyuas ntawm qhov chaw, suav nrog kev teeb tsa, kev nyeem cov ntaub ntawv, kev hloov kho firmware thiab lwm yam.
NB kev sib txuas lus: Lub module cuam tshuam nrog lub platform los ntawm NB network.
Metering: Txhawb ib leeg nrog sensor metering
Cov ntaub ntawv khov txhua hnub: Sau cov dej ntws ntawm cov hnub dhau los thiab tuaj yeem nyeem cov ntaub ntawv ntawm 24 lub hlis dhau los tom qab lub sijhawm ntsuas.
Cov ntaub ntawv khov txhua hli: Sau cov dej ntws ntawm hnub kawg ntawm txhua lub hli thiab tuaj yeem nyeem cov ntaub ntawv ntawm 20 xyoo dhau los tom qab lub sijhawm ntsuas.
Cov ntaub ntawv hnyav ib teev: Siv 00:00 txhua hnub raws li lub sijhawm pib siv, sau cov mem tes nce ntxiv txhua teev, thiab lub sijhawm tshaj tawm yog lub voj voog, thiab khaws cov ntaub ntawv hnyav ib teev hauv lub sijhawm.
Disassembly tswb: Tshawb xyuas qhov teeb tsa module teeb tsa txhua thib ob, yog tias cov xwm txheej hloov pauv, lub tswb cuam tshuam keeb kwm yuav raug tsim tawm.Lub tswb yuav pom tseeb tsuas yog tom qab kev sib txuas lus module thiab lub platform ntse sib txuas lus ib zaug.
Magnetic nres tswb: Thaum cov hlau nplaum nyob ze rau Hall sensor ntawm lub ntsuas ntsuas module, sib nqus nres thiab keeb kwm sib nqus nres yuav tshwm sim.Tom qab tshem tawm cov hlau nplaum, qhov sib nqus nres yuav raug muab tso tseg.Cov keeb kwm sib nqus nres yuav tsuas yog muab tso tseg tom qab cov ntaub ntawv tau tshaj tawm rau lub platform.
