LoRaWAN Dual-mode Meter Reading Module

Zida Zadongosolo

HAC-MLLW (LoRaWAN dual-mode meter reading module), HAC-GW-LW (LoRaWAN gateway), HAC-RHU-LW (LoRaWAN handhels) ndi nsanja yoyendetsera deta.

System Features

1. Kulankhulana kwakutali kwambiri

• LoRa modulation mode, mtunda wautali wolankhulana.

• Kulankhulana kowoneka mtunda pakati pa Gateway ndi Meter: 1km-5km m'matawuni, 5-15km kumidzi.

•  Mlingo wa kulumikizana pakati pa chipata ndi mita ndi chosinthika, pozindikira kulumikizana kwautali kwambiri pamlingo wochepa.

• Zogwirizira m'manja zimakhala ndi mtunda wautali wowerengera wowonjezera, ndipo kuwerengera kwa mita ya batch kumatha kuchitidwa ndi kuwulutsa mkati mwa 4km.

2. Kugwiritsa ntchito mphamvu zotsika kwambiri, moyo wautali wautumiki

• Avereji yogwiritsa ntchito mphamvu ya module yapawiri-mode-mapeto ndi yochepera kapena yofanana ndi 20µA, popanda kuwonjezera mabwalo owonjezera a hardware ndi ndalama.

• Module ya mita imanena za data maola 24 aliwonse, yoyendetsedwa ndi batire ya ER18505 kapena mphamvu yofanana yomwe ingagwiritsidwe ntchito kwa zaka 10.

3. Anti-kusokoneza, kudalirika kwakukulu

•  Kusintha kwa ma frequency angapo ndi ma multi-rate automatic kuti mupewe kusokoneza ma tchanelo ndikuwongolera kudalirika kotumizira.

• Landirani ukadaulo wapatent wa kulumikizana kwa TDMA kuti mulunzanitse nthawi yolumikizirana kuti mupewe kugundana kwa data.

• Kutsegula kwa mpweya kwa OTAA kumatengedwa, ndipo kiyi yobisa imapangidwa yokha ikalowa pa netiweki.

•  Detayo imabisidwa ndi makiyi angapo achitetezo chapamwamba.

4. Mphamvu zazikulu zowongolera

• Chipata chimodzi cha LoRaWAN chikhoza kuthandizira mpaka mamita 10,000.

•  Itha kusunga zaka 10 zachisanu zapachaka komanso zachisanu pamwezi m'miyezi 128 yapitayi.Pulatifomu yamtambo imatha kufunsa mbiri yakale.

• Landirani ma aligorivimu osinthika a kuchuluka kwa kufala ndi mtunda wotumizira kuti muwongolere bwino mphamvu zamakina.

•  Kukula kwadongosolo kosavuta: kumagwirizana ndi mita yamadzi, mita ya gasi ndi mita ya kutentha, yosavuta kuonjezera kapena kutsika, zipata zapakhomo zitha kugawidwa.

• Kugwirizana ndi LORAWAN1.0.2 protocol, kukulitsa ndikosavuta, ndipo mphamvu imatha kuwonjezeredwa powonjezera chipata.

5. Zosavuta kukhazikitsa ndikugwiritsa ntchito, kuchuluka kwabwino kwa kuwerenga kwa mita

• Gawoli limagwiritsa ntchito njira yolumikizira netiweki ya OTAA, yomwe ndi yosavuta kugwiritsa ntchito komanso yosavuta kuyisamalira.

•  Chipata chokhala ndi njira zambiri chimatha kulandira nthawi imodzi data ya ma frequency angapo komanso kuchuluka.

• Magawo omaliza a mita ndi chipata amalumikizidwa ndi netiweki ya nyenyezi, yomwe ndi mawonekedwe osavuta, kulumikizana kosavuta komanso kuwongolera kosavuta komanso kukonza.
