Imitha yokuxhumana ye-RF yesigaba sesithathu-sesine -iyimitha yokuxhumana ye-RF-enembayo ekhokha kusengaphambilini yamandla kagesi ehlanganisa ubuchwepheshe bokuxhumana be-RF(Radio Frequency), ukuthobela okuqinile kwe-IEC, kanye{3}}nobubanzi bemisebenzi yokuphatha amandla. Ihlukile kumamitha endabuko athembele ekuxhumaneni ngezintambo, imojuli yayo eyakhelwe-nge-RF inika amandla ukudluliswa kwedatha okungenantambo, kwephule umkhawulo woxhumano olunezintambo futhi ibe idivayisi ebalulekile yezinsiza zokwakha "inethiwekhi yokulinganisa amandla ehlakaniphile engenantambo".

I-Design Core
"Ngokusebenza kahle okungenantambo + ukunemba kwemitha + lula komsebenzisi" njengomqondo womklamo oyinhloko, le mitha yesigaba esi-3 esikhokhelwa ngaphambili ayifinyeleli kuphela izidingo eziyisisekelo zesigaba samandla asebenzayo esingu-1.0 kanye nesigaba samandla asebenzayo esingu-2.0 kodwa futhi ithuthukisa ukuzinza kokuxhumana kwe-RF ezindaweni eziyinkimbinkimbi zasendlini/zangaphandle. Iqinisekisa ukudluliswa okuthembekile okungenantambo kwedatha yemitha, ulwazi lokushajwa kabusha, namarekhodi omcimbi, kuyilapho yenza lula-ukufakwa kwesayithi (asikho isidingo sokubeka izintambo zokuxhumana) futhi yehlisa izindleko zokulungisa kamuva zohlelo lokulinganisa.

IP54 Ukuvikelwa kwe-RF Module
Ileveli yokuvikela ye-prepaid meter yesigaba esi-3 ifinyelela ku-IP54, engavimbela ngempumelelo ukunqwabelana kothuli nokuchaphaza kwamanzi ukuthi angangeni ngaphakathi. Imojula ye-RF, njengengxenye ewumgogodla, ifakwa endaweni evalekile yemitha, igwema ukuwohloka kokusebenza okubangelwa uthuli noma umswakama. Lokhu kuqinisekisa ukuxhumana okuzinzile kwe-RF ngisho nasezindaweni ezingaphandle ezivulekile-ezinjengamaphasishi okwakha, amabhokisi amamitha angaphandle).
{{0}Ukusebenza Kwe-RF Yamandla Aphansi
Imojula ye-RF isebenzisa{{0}isakhiwo samandla aphansi, futhi ukusetshenziswa kwamandla kukonke kwemitha kulawulwa ngezinga eliphansi (amanje okusebenzayo<30μA when powered on, 0.1μA-2μA when powered off). The low-power RF operation not only reduces the meter's own energy consumption but also extends the service life of the built-in lithium battery (1200mAh), ensuring continuous RF communication even during short-term power outages.
Izitifiketi
Imitha ithole izitifiketi eziningi ezigunyaziwe ukuze ihlangabezane nezidingo zokufinyelela ezimakethe zomhlaba.
