-139dbm ukuzwela kwedatha okudluliswayo kwe-LoRa DTU okufakwe kumojuli ye-LoRa DTU

-139dbm ukuzwela kwedatha okudluliswayo kwe-LoRa DTU okufakwe kumoduli efakiwe Isithombe Esivelele

Incazelo emfushane:

I-LORA DTU module_MDL210 embedded terminal yiyo esebenzisa ubuchwepheshe be-LoRa spread spectrum ekudlulisweni kwedatha okungenantambo, okunikeza abasebenzisi imodi yokudlulisa idatha esobala ngokuphelele engenaphrothokholi. Udinga nje ukusetha amapharamitha ambalwa alula ukuze ufinyelele izindlela eziningi zokuxhumana ezifana nokuxhumana kwezinkanyezi kanye nenethiwekhi ye-Mesh. Kukhona nezindlela eziningi zokuxhumana ezifana nokufunwa, ukusakaza, kanye nokusakaza okuningi kunethiwekhi efanayo;
I-interface yokuxhumana ye-TTL inikezwa, Inethiwekhi yemishini ye-port port yezimboni enobungani nomsebenzisi, ukunikezwa kwamandla kwemishini kusebenzisa uhla olubanzi lokuklama ukusetshenziswa kwamandla aphansi (≤40uA@5V).

-139dbm ukudluliswa kwedatha okuzwela kakhulu kwesamukeliokufakiweImojula ye-LoRa DTU

I-terminal embedded ye-LORA DTU module_MDL210 yileyo esebenzisa ubuchwepheshe be-LoRa spread spectrum ekudlulisweni kwedatha okungenantambo, inikeza abasebenzisi imodi yokudlulisa idatha esobala ngokuphelele engenaphrothokholi.Udinga nje ukusetha amapharamitha ambalwa alula ukuze ufinyelele izindlela eziningi zokuxhumana njengokuxhumana kwezinkanyezi kanye nenethiwekhi ye-Mesh. Kukhona futhi izindlela eziningi zokuxhumana ezifana nokufunwa, ukusakaza, kanye nokusakaza okuningi kunethiwekhi efanayo;

I-interface yokuxhumana ye-TTL inikezwa, Inethiwekhi yemishini ye-port port yezimboni enobungani nomsebenzisi, ukunikezwa kwamandla kwemishini kusebenzisa uhla olubanzi lokuklama ukusetshenziswa kwamandla aphansi (≤40uA@5V).

Ubuchwepheshe be-LoRa bunozwela olukhulu kakhulu lokwamukelwa (i-RSSI) kanye

i-super signal-to-noise (SNR) kanye nobuchwepheshe bethu bokusekela imodemu kanye nokusebenza komkhiqizo okuzinzile nokuthembekile.

Imojula engenantambo ye-LoRa inekhono elinamandla kakhulu lokulwa nokuphazamiseka.

I-MDL210 ibambisana ne-4G DTU yenkampani yethu, engasiza ekusungulweni kwesango le-LoRa ukuze kufezwe ukudluliswa kwedatha okude.

Ukuxhumana kokusakaza

Ngaphansi kwenethiwekhi efanayo, idivayisi ngayinye iyaxhumana

Ukuxhumana ngamaphuzu - iphuzu

Ngaphansi kwenethiwekhi efanayo, ukuxhumana okuqondile

phakathi kwanoma yimaphi amadivayisi amabili kungatholakala

Ukuxhumana kwe-Multicast

Ngaphansi kwenethiwekhi efanayo, amadivayisi owodwa noma amaningi angasethwa njengeqembu ukuze kufezwe ukuxhumana kweqembu neqembu

Izindlela ezintathu zokuxhumana ezingenhla zingahlanganiswa kunethiwekhi efanayo

Ngaphezu kokusebenzisa ikhebula le-serial lendawo ukumisa ngqo amapharamitha edivayisi ye-MIND LoRa,futhi isekela ngaphandle kwentamboukumisa amapharamitha edivayisi ekude.

Njengoba kuboniswe ku-FIG:

Idivayisi ye-A ixhunywe kwikhompyutha ngekhebula elilandelanayo, futhi isofthiwe yokucushwa kwezithombe enikezwa yinkampani yethu ingasetshenziswa ukumisa amapharamitha edivayisi yendawo ye-A kalula nangokushesha, futhi amapharamitha edivayisi ekude ye-B nawo angamiswa ngaphandle kwentambo.

*Ukuze ulungiselele amapharamitha kwimodi engenantambo, qiniseka ukuthi idivayisi yendawo kanye nedivayisi ekude zikunethiwekhi efanayo

Kusukela ngo-2015, inkampani yethu isiqalile ukuthuthukisa nokukhiqiza imikhiqizo yochungechunge lwe-LoRa, ngokuthunyelwa okuhlanganisiwe kwamayunithi angaphezu kuka-5,000. Eminyakeni emibili edlule, imikhiqizo yochungechunge lwe-LoRa isetshenziswe ngempumelelo kuphrojekthi ethi “Isexwayiso Sangaphambi Kwenhlekelele Yezikhukhula Zezintaba Kazwelonke” inkampani yethu ehlanganyele kuyo. Amaqiniso afakazele ukuthi thina Ngezici zayo zekhwalithi ephezulu, ukuzinza okuphezulu, kanye nesiqinisekiso esiphezulu, imikhiqizo yayo iye yaqashelwa embonini futhi inedumela elihle phakathi kwamakhasimende.
