Qib IndustrialNB-IoTDTU
Txhawb CoAP raws tu qauv, Tuam Tshoj Telecom Huab,NB-IoT,
LPWAN, txhawb nqa cov roj teeb sab nraud
ZSN311 NB-IoT DTU yog lub davhlau ya nyob twg sab nraud raws li NB-IoT rau kev xa cov ntaub ntawv wireless, ntim me me, txhawb ntau qhov sib cuam tshuam; txhawb nqa online, IDLE, PSM raws li txoj cai, tau txais kev siv hluav taws xob qis dua; Txhawb UDP/CoAP network raws tu qauv, muab tag nrho cov ntaub ntawv sib kis hom rau cov neeg siv; Txhawb customized pob ntawv lub plawv dhia, sau npe pob ntawv, header; Txhawb nqa peb tus kheej tsim IoT huab yam tsis muaj lub tsev server los ntawm cov neeg siv; Txhawb nqa kev lag luam SCADA tag nrho, cov neeg siv tsis tas yuav saib xyuas cov txheej txheem sib txuas sib txuas, tsuas yog los ntawm cov pob tshab sib kis tag nrho koj tuaj yeem ua tiav cov ntaub ntawv xa & txais wireless, ua rau koj lub cuab yeej txuas rau hauv Is Taws Nem yam tsis muaj kev txwv ntawm lub sijhawm lossis qhov chaw.
Siv Quectel Industrial Qib Kev Sib Txuas Lus Chip
MDN311-485 siv Quectel Industrial Grade Communication Chip kom ua tau zoo lav tsis muaj kev cuam tshuam NB-IoT kev sib txuas lus network.

Cov cuab yeej khiav nrog tsawg zog noj thiab tsis tuaj yeem tau txais cov ntaub ntawv downlink los ntawm cov ntaub ntawv chaw.
Lub DTU yuav tsum nquag upload cov ntaub ntawv thiab nkag mus rau hom kev sib txuas ua ntej lub chaw tuaj yeem xa cov ntaub ntawv.
Tom qab tsis muaj cov ntaub ntawv sib txuas lus, MDN311 cia li nkag mus rau PSM hom kom tswj tau lub zog siv hluav taws xob tsawg.
MDN311 txhawb nqa cov ntawv sau ua haujlwm. Cov neeg siv tuaj yeem hloov kho cov ntawv sau los ntawm cov duab teeb tsa software ntawm cov cuab yeej, kom cov ntawv thov ntawm qhov chaw tsis tas yuav muaj cov tswj hwm ntxiv, thiab tsis tas yuav cia siab rau cov ntaub ntawv platform los tshaj tawm cov lus qhia sau kom ua tiav kev sib txuas ncaj qha rau lub ntsuas. MDN311 Ncaj nraim thiab nquag sau cov ntaub ntawv los ntawm cov cuab yeej thiab tshaj tawm rau lub platform.
Hloov cov ntaub ntawv pob ntawv hom Customization
Kev cai sau npe pob ntawv:Cov neeg siv tuaj yeem tsim kho cov ntsiab lus ntawm cov ntaub ntawv xa tawm thaum MDN311 thawj zaug txuas nrog cov ntaub ntawv chaw.
Custom Heartbeat Packet:Cov neeg siv tuaj yeem tsim kho cov ntsiab lus ntawm lub plawv dhia pob ntawv xa los ntawm MDN311 mus rau qhov chaw khaws ntaub ntawv.
Custom header pob ntawv:Tus neeg siv tuaj yeem teeb tsa cov ntsiab lus tshwj xeeb ua ntej cov ntaub ntawv xa los ntawm DTU mus rau qhov chaw khaws ntaub ntawv txhawm rau paub qhov txawv ntawm cov ntaub ntawv lossis qeb.
