I-LoRaWAN Imoduli Yokufunda Yemitha Yemodi Ekabili yesithombe Esifakiwe

I-LoRaWAN Imojuli Yokufunda Yemitha Embili

Incazelo emfushane:

II-HAC-MLLWImojula yokufunda yamamitha angenawaya ye-LoRaWAN yemodi ekabili ithuthukiswe ngokusekelwe kuphrothokholi evamile ye-LoRaWAN Alliance, ene-topology yenethiwekhi yenkanyezi. Isango lixhunywe kunkundla yokuphathwa kwedatha ngesixhumanisi se-IP esivamile, futhi idivayisi yetheminali ixhumana nesango eligxilile elilodwa noma amaningi ngephrothokholi evamile Yekilasi A le-LoRaWAN.

Uhlelo luhlanganisa ukufundwa kwamamitha enethiwekhi yendawo ebanzi ye-LoRaWAN kanye ne-LoRa Walk-ngokufunda okungeziwe okuphathwa ngesandla okungenantambo. Isandlasingasetshenziswaokweukufunda okungeziwe okukude okungenantambo, ukulungiselelwa kwepharamitha, isilawuli sevalvu yesikhathi sangempela,okukodwa-ukufundwa kwamaphoyinti nokusakaza imitha kumamitha endaweni eyimpumputhe yesignali. Isistimu yakhelwe esebenzisa amandla aphansi kanye nebanga elide lokungeziweukufunda. Itheminali yamamitha isekela izindlela ezahlukahlukene zokulinganisa ezifana ne-non-magnetic inductance, ikhoyili engeyona-magnetic, isilinganiso se-ultrasonic, iHholo.inzwa, i-magnetoresistance kanye nokushintsha komhlanga.

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 egesi namamitha okushisa, kulula ukuwandisa 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.
