LoRaWAN nta
| Tsis muaj. | Feature | Function Description |
| 1 | Cov ntaub ntawv qhia | Muaj ob txoj hauv kev qhia cov ntaub ntawv. Kov kom tshaj tawm cov ntaub ntawv: Koj yuav tsum kov lub khawm kov ob zaug, kov ntev (ntau dua 2 vib nas this) + luv kov (tsawg dua 2 vib nas this), thiab ob qhov kev ua yuav tsum ua kom tiav hauv 5 vib nas this, txwv tsis pub tus txhais yuav siv tsis tau. Timing active data reporting: Lub sij hawm qhia txog lub sij hawm thiab lub sij hawm qhia lub sij hawm tuaj yeem teem tau.Tus nqi ntau ntawm lub sijhawm qhia lub sijhawm yog 600 ~ 86400s, thiab tus nqi ntau ntawm lub sijhawm qhia lub sijhawm yog 0 ~ 23H.Tom qab teeb tsa, lub sijhawm tshaj tawm yog xam raws li DeviceEui ntawm lub cuab yeej, lub sijhawm qhia lub sijhawm thiab lub sijhawm qhia txog lub sijhawm.Tus nqi pib ntawm lub sijhawm tshaj tawm tsis tu ncua yog 28800s, thiab tus nqi pib ntawm lub sijhawm tshaj tawm yog 6H. |
| 2 | Kev ntsuas | Txhawb hom kev ntsuas tsis sib nqus |
| 3 | Lub zog-down cia | Txhawb lub zog-down cia muaj nuj nqi, tsis tas yuav rov pib qhov ntsuas tus nqi tom qab fais fab tuag. |
| 4 | Disassembly tswb | Thaum qhov ntsuas kev sib hloov mus rau pem hauv ntej yog ntau dua 10 pulses, lub tswb tiv thaiv kev ua haujlwm yuav muaj.Thaum lub cuab yeej disassembled, lub disassembly cim thiab keeb kwm disassembly cim yuav pom faults tib lub sij hawm.Tom qab cov cuab yeej raug teeb tsa, qhov ntsuas kev sib hloov mus rau pem hauv ntej yog ntau dua 10 pulses thiab kev sib txuas lus nrog cov khoom siv tsis sib nqus yog qhov qub, qhov kev cuam tshuam ntawm kev sib tsoo yuav raug tshem tawm. |
| 5 | Txhua hli thiab txhua xyoo khov cov ntaub ntawv khaws cia | Nws tuaj yeem txuag tau 10 xyoo ntawm cov ntaub ntawv khov txhua xyoo thiab cov ntaub ntawv khov txhua hli ntawm 128 lub hlis dhau los, thiab huab platform tuaj yeem nug cov ntaub ntawv keeb kwm |
| 6 | Kev teeb tsa Parameter | Txhawb wireless nyob ze thiab tej thaj chaw deb parameter chaw.Kev teeb tsa tej thaj chaw deb yog pom tau los ntawm huab platform.Qhov chaw nyob ze yog pom tau los ntawm cov cuab yeej ntsuas kev tsim khoom, piv txwv li kev sib txuas lus wireless thiab kev sib txuas lus infrared. |
| 7 | Txhim kho firmware | Txhawb kev hloov kho infrared |
