LoRaWAN Imodyuli yokuFunda yeemitha ezimbini-imodyuli eboniswayo

Imodyuli yokuFunda yeemitha ye-LoRaWAN yeemodyuli ezimbini

Inkcazelo emfutshane:

IHAC-MLLWImodyuli yokufunda yemitha engenazingcingo ye-LoRaWAN iphuhliswe ngokusekwe kwiprotocol yomgangatho weLoRaWAN Alliance, kunye netopology yenethiwekhi yenkwenkwezi. Isango lixhunywe kwiqonga lolawulo lwedatha ngokusebenzisa ikhonkco eliqhelekileyo le-IP, kwaye isixhobo se-terminal sinxibelelana nesango elinye okanye ezininzi ezisisigxina ngeLoRaWAN Class A standard protocol.

Inkqubo idibanisa i-LoRaWAN esisigxina yokufundwa kwemitha yemitha ye-wireless ebanzi kunye ne-LoRa Walk-ngokufunda okongezelelweyo okungenazingcingo. Ukubanjwa ngesandlasinokusetyenziswangenxaufundo olongezelelweyo olungenazingcingo, ukusetwa kweparamitha, ulawulo lwevalvu yexesha langempela,mnye-ukufundwa kweengongoma kunye nokufundwa kwemitha yosasazo kwiimitha kwindawo yokungaboni ngasonye. Inkqubo yenzelwe ukusetyenziswa kwamandla aphantsi kunye nomgama omde wokongezaukufunda. Itheminali yemitha ixhasa iindlela ezahlukeneyo zokulinganisa ezifana ne-non-magnetic inductance, coil non-magnetic, umlinganiselo we-ultrasonic, iHolo.isivamvo, imagnetoresistance kunye nokutshintsha kweengcongolo.

Amacandelo eNkqubo

I-HAC-MLLW (i-LoRaWAN imodyuli yokufunda yeemitha ezimbini zemodyuli), i-HAC-GW-LW (isango le-LoRaWAN), i-HAC-RHU-LW (i-LoRaWAN handhels) kunye neqonga lolawulo lwedatha.

Iimpawu zeNkqubo

1. Unxibelelwano lomgama omde kakhulu

Imowudi yokumodareyitha ye-LoRa, umgama omde wonxibelelwano.

Umgama wonxibelelwano olubonakalayo phakathi kweSango neMeta: 1km-5km kubume bendawo yasezidolophini, 5-15km kwindawo esemaphandleni.

Ireyithi yonxibelelwano phakathi kwesango kunye nemitha iyaguquguquka, iqonda owona mgama omde wonxibelelwano kwizinga eliphantsi.

Izinto eziphathwayo zinomgama omde wokufunda owongezelelweyo, kwaye ukufundwa kweemitha zebhetshi kunokuqhutywa ngosasazo phakathi koluhlu lwe-4km.

2. Ukusetyenziswa kwamandla aphantsi kakhulu, ubomi benkonzo ende

Umndilili wokusetyenziswa kwamandla kwimodyuli yokuphela kwemitha yemodyuli ingaphantsi okanye ilingana ne-20µA, ngaphandle kokongeza iisekethe ezongezelelweyo zehardware kunye neendleko.

Imodyuli yemitha ibika idatha rhoqo kwiiyure ezingama-24, inikwe amandla ngebhetri ye-ER18505 okanye umthamo olinganayo ungasetyenziselwa iminyaka eyi-10.

3. Ukuchasana nokuphazamiseka, ukuthembeka okuphezulu

I-Multi-frequency kunye ne-multi-rate yokutshintsha ngokuzenzekelayo ukuphepha ukuphazamiseka kwe-co-channel kunye nokuphucula ukuthembeka kokuhanjiswa.

Yamkela itekhnoloji enelungelo elilodwa lomenzi wonxibelelwano lwe-TDMA ukulungelelanisa ngokuzenzekelayo iyunithi yexesha lonxibelelwano ukunqanda ukungqubana kwedatha.

Ukusebenza komoya kwe-OTAA kwamkelwe, kwaye iqhosha lokufihla lenziwa ngokuzenzekelayo xa kungena inethiwekhi.

Idatha iguqulelwe ngokuntsonkothileyo ngezitshixo ezininzi zokhuseleko oluphezulu.

4. Amandla amakhulu olawulo

Isango elinye leLoRaWAN linokuxhasa ukuya kuthi ga kwi-10,000 yeemitha.

Ingagcina idatha yeminyaka eli-10 yomkhenkce kunye nenyanga engumkhenkce kwiinyanga ezili-128 ezidlulileyo. Iqonga lelifu lingabuza idatha yembali.

Yamkela i-algorithm yokuguquguquka yesantya sothumelo kunye nomgama wothumelo ukuze uphucule ngokufanelekileyo umthamo wenkqubo.

Ukwandiswa kwenkqubo elula: iyahambelana nemitha yamanzi, iimitha zegesi kunye nemitha yokushisa, kulula ukwandisa okanye ukunciphisa, izibonelelo zesango zingabelana.

Ukuhambelana neprotocol ye-LORAWAN1.0.2, ukwandiswa kulula, kwaye umthamo unokunyuswa ngokongeza isango.

5. Kulula ukuyifaka kunye nokusetyenziswa, izinga eliphezulu lempumelelo yokufunda imitha

Imodyuli ithatha indlela yokufikelela kwinethiwekhi ye-OTAA, ekulula ukuyisebenzisa kwaye kulula ukuyigcina.

Isango elinoyilo lweetshaneli ezininzi ngaxeshanye linokufumana idatha ye-multi-frequency kunye ne-multi-rate.

Imodyuli yokuphela kweemitha kunye nesango lixhunyiwe kwinethiwekhi yeenkwenkwezi, okuyisakhiwo esilula, uxhulumaniso olufanelekileyo kunye nolawulo olulula kunye nokugcinwa.
