I-LoRaWAN Imojuli Yokufunda Yemitha Embili

Izingxenye Zesistimu

I-HAC-MLLW (imojula yokufunda imitha ye-LoRaWAN enemodi ekabili), i-HAC-GW-LW (isango le-LoRaWAN), i-HAC-RHU-LW (izandla ze-LoRaWAN) kanye nesiteji sokuphatha idatha.

Izici Zesistimu

1. Ukuxhumana kwebanga elide kakhulu

• Imodi yokushintshashintsha ye-LoRa, ibanga elide lokuxhumana.

• Ibanga lokuxhumana elibonakalayo phakathi kweSango neMetha: 1km-5km endaweni yasemadolobheni, 5-15km endaweni yasemakhaya.

•  Izinga lokuxhumana phakathi kwesango nemitha liyaguquguquka, libona ukuxhumana kwebanga elide kakhulu ngenani eliphansi.

• Izibambo zezandla zinebanga elide lokufunda elengeziwe, kanti ukufundwa kwemitha yeqoqo kungenziwa ngokusakaza phakathi kwebanga elingu-4km.

2. Ukusetshenziswa kwamandla okuphansi kakhulu, impilo ende yesevisi

• Ukusetshenziswa kwamandla okumaphakathi kwemojuli yokuphela kwemitha yemodi ekabili kungaphansi noma kulingana nama-20µA, ngaphandle kokungeza amasekhethi ezingxenyekazi zekhompiyutha ezengeziwe nezindleko.

• Imojuli yemitha ibika idatha njalo emahoreni angama-24, inikwe amandla ngebhethri elingu-ER18505 noma umthamo olinganayo ungasetshenziswa iminyaka eyi-10.

3. Ukuvimbela ukuphazamiseka, ukwethembeka okuphezulu

•  I-Multi-frequency kanye ne-multi-rate switch othomathikhi ukuze ugweme ukuphazamiseka kwe-co-channel kanye nokuthuthukisa ukuthembeka kokudlulisela.

• Sebenzisa ubuchwepheshe obunelungelo lobunikazi bokuxhumana kwe-TDMA ukuze uvumelanise ngokuzenzakalela iyunithi yesikhathi sokuxhumana ukugwema ukungqubuzana kwedatha.

• Ukusebenza komoya kwe-OTAA kwamukelwa, futhi ukhiye wokubethela ukhiqizwa ngokuzenzakalelayo lapho kungena inethiwekhi.

•  Idatha ibethelwe ngokhiye abaningi bokuphepha okuphezulu.

4. Amandla amakhulu okuphatha

• Isango elilodwa le-LoRaWAN lingakwazi ukusekela kufika kumamitha angu-10,000.

•  Ingonga idatha yeminyaka eyi-10 yonyaka eqandisiwe kanye nefriziwe yanyanga zonke ezinyangeni zokugcina eziyi-128.Inkundla yefu ingabuza idatha yomlando.

• Sebenzisa i-algorithm eguquguqukayo yezinga lokudlulisela kanye nebanga lokudlulisela ukuze uthuthukise ngempumelelo umthamo wesistimu.

•  Ukwandiswa kohlelo olulula: oluhambisana namamitha amanzi, amamitha wegesi namamitha okushisa, kulula ukwandisa noma ukuncipha, izinsiza zesango zingabiwa.

• Ngokuhambisana nephrothokholi ye-LORAWAN1.0.2, ukunwetshwa kulula, futhi umthamo ungandiswa ngokungeza isango.

5. Kulula ukufaka nokusebenzisa, izinga eliphezulu lempumelelo yokufunda imitha

• Imojula isebenzisa indlela yokufinyelela inethiwekhi ye-OTAA, okulula ukuyisebenzisa futhi kulula ukuyinakekela.

•  Isango elinomklamo onamashaneli amaningi lingathola kanyekanye idatha ye-multi-frequency kanye ne-multi-rate.

• Imojula yokuphela kwamamitha kanye nesango kuxhunywe kunethiwekhi yenkanyezi, okuyisakhiwo esilula, ukuxhumana okulula nokuphathwa nokugcinwa okulula.
