IBanga loShishinoI-NB-IoTI-DTU
Inkxaso yeProtocol yeCoAP, iLifu leTelecom laseChina, iNB-IoT,
I-LPWAN, ixhasa unikezelo lwamandla ebhetri lwangaphandle
I-ZSN311 NB-IoT DTU yitheminali yangaphandle esekwe kwi-NB-IoT yokuhanjiswa kwedatha engenazingcingo, umthamo omncinci, uxhasa ujongano oluninzi; xhasa i-intanethi, i-IDLE, imo yePSM, fumana ukusetyenziswa kwamandla okulinda okusezantsi;Inkxaso ye-protocol ye-UDP/CoAP network network, ebonelela ngemowudi yokuhanjiswa kwedatha ecacileyo ngokupheleleyo kubasebenzisi;Ixhasa ipakethi yokubetha kwentliziyo, ipakethi yobhaliso, iheda;Xhasa i-IoT Cloud yethu eyakhiweyo ngaphandle kokwakha iseva ngabasebenzisi;Ixhasa ngokupheleleyo iSCADA yemizi-mveliso, abasebenzisi akufuneki bakhathalele iprothokholi yenethiwekhi entsonkothileyo, ngothumelo olupheleleyo lweseriyeli ungafikelela ekuthumeleni idatha engenazingcingo & nerecei, wenze isixhobo sakho siqhagamshele kwi-Intanethi ngaphandle kokuthintelwa kwexesha okanye indawo.
Ukusebenzisa iQuectel Industrial Grade Communication Chip
I-MDN311-485 isebenzisa i-Quectel Industrial Grade Communication Chip ukuze iqinisekise ngokufanelekileyo unxibelelwano lwenethiwekhi ye-NB-IoT engaphazanyiswa.
Iprotocol ye-MDN311 yenkxaso ye-CoAP
I-NB-IoT DTU inokukhetha i-Mind IoT Cloud/China Telecom IoT Cloud

Isixhobo sisebenza ngokusetyenziswa kwamandla aphantsi kwaye asikwazi ukufumana idatha ye-downlink kwiziko ledatha.
I-DTU kufuneka ifake idatha ngokusebenzayo kwaye ifake imo yoqhagamshelwano phambi kokuba iziko lithumele idatha.
Emva kokungabikho konxibelelwano lwedatha, i-MDN311 ingena ngokuzenzekelayo kwimodi ye-PSM ukugcina ukusetyenziswa kwamandla aphantsi kokulinda.
I-MDN311 ixhasa umsebenzi wodweliso lweskripthi.Abasebenzisi banokwenza iifayile zeskripthi ngokwezifiso ngokusebenzisa i-software ye-graphical configuration yesixhobo, ukwenzela ukuba izicelo ze-site azifuni abalawuli abongezelelweyo, kwaye akufuneki ukuba bathembele kwiqonga ledatha ukukhupha imiyalelo yokuqokelela ukufikelela ngqo kwisixhobo.I-MDN311 ngokuthe ngqo kwaye iqokelele idatha kwisixhobo kwaye uyixele kwiqonga.
ULungiselelo lwePakethi yePakethi yeDatha eNgcono
Ipakethi yokubhalisa ngokwezifiso:Abasebenzisi banokuqwalasela ngokukhululekileyo umxholo wepakethi yedatha ethunyelwe xa i-MDN311 ixhunywe okokuqala kwiziko ledatha.
Ipakethi yesiqhelo sokubetha kwentliziyo:Abasebenzisi banokuqwalasela ngokukhululekileyo umxholo wepakethi yokubetha kwentliziyo ethunyelwe yi-MDN311 kwiziko ledatha.
Ipakethi yesihloko esilungiselelweyo:Umsebenzisi unokuqwalasela umxholo othile phambi kokuba ipakethe yedatha ithunyelwe yi-DTU kwiziko ledatha ukwenzela ukwahlula uhlobo lwedatha okanye udidi.
