-139dbm umamukeli wedatha ezwelayo yokudlulisa imojula eshumekiwe ye-LoRa DTU

-139dbm umamukeli wedatha ezwelayo ephezulu yokudlulisa eshumekwe imojula ye-LoRa DTU Isithombe Esifakiwe

Incazelo emfushane:

Itheminali eshumekiwe ye-LORA DTU module_MDL210 yileyo esebenzisa ubuchwepheshe be-LoRa spread spectrum ekudluliselweni kwedatha okungenantambo, ihlinzeka abasebenzisi ngemodi yokudlulisa idatha esobala ngokugcwele engenaphrothokholi.Udinga kuphela ukusetha amapharamitha ambalwa ukuze uzuze izindlela eziningi zokuxhumana ezifana nenkanyezi enenethiwekhi nenethiwekhi ye-Mesh.Kukhona futhi izindlela zokuxhumana eziningi ezifana nokufunwayo, ukusakaza, nokusakaza okuningi kunethiwekhi efanayo;
I-interface ye-TTL yokuxhumana inikeziwe, Inethiwekhi yemishini ye-serial port yezimboni esebenziseka kalula, ukunikezwa kwamandla kwemishini kusebenzisa idizayini ebanzi yokusetshenziswa kwamandla okuphansi(≤40uA@5V).

Ubuchwepheshe be-LoRa ngokwabo bunokuzwela kwerecei ephezulu kakhulu (RSSI) kanye

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

Imojula engenantambo ye-LoRa inekhono eliqinile lokulwa nokuphazamiseka.

I-MDL210 ibambisana ne-4G DTU yenkampani yethu, engakwazi ukusiza ukusungulwa kwesango le-LoRa ukuze kutholakale ukudluliswa kwedatha okukude.

Ukuxhumana kokusakaza

Ngaphansi kwenethiwekhi efanayo, idivayisi ngayinye ixhumana nenye

Iphuzu - iphuzu lokuxhumana

Ngaphansi kwenethiwekhi efanayo, ukuxhumana kwephoyinti

phakathi kwanoma yimaphi amadivaysi amabili angabonakala

Ukuxhumana kokusakaza okuningi

Ngaphansi kwenethiwekhi efanayo, idivayisi eyodwa noma eziningi zingasethwa njengeqembu ukuze kutholakale ukuxhumana kweqembu neqembu

Izindlela ezintathu zokuxhumana ezingenhla zingahlanganiswa kunethiwekhi efanayo

Ngaphezu kokusebenzisa ikhebula le-serial lasendaweni ukuze ulungiselele ngokuqondile imingcele yedivayisi ye-MIND LoRa,iphinde isekele ngokungenantamboukulungisa amapharamitha wedivayisi ekude.

Njengoba kuboniswe ku-FIG:

Idivayisi A ixhunywe kukhompuyutha ngekhebula le-serial, futhi isofthiwe yokumisa isithombe enikezwe inkampani yethu ingasetshenziswa ukulungisa amapharamitha wedivayisi yasendaweni A kalula nangokushesha, futhi nemingcele yedivayisi ekude B nayo ingalungiselelwa. ngokungenantambo.

*Ukuze ulungiselele amapharamitha kumodi engenantambo, qinisekisa ukuthi idivayisi yasendaweni nesilawuli kude kunethiwekhi efanayo
