Kulezi zindlela zokusebenza ezintathu ezingenhla, i-MDLR311 ingathumela futhi yamukele idatha, futhi imingcele eshiwo ngenhla iyidatha elinganiswayo.
Ubuchwepheshe be-LoRa bunokuzwela kwerecei okuphezulu (i-RSSI) kanye nesilinganiso somsindo we-signal-to-noise (SNR), kuhlanganiswe nobuchwepheshe bethu bokushintshashintsha nokudilizwa kwempahla, umkhiqizo ongenazintambo we-LoRa unekhono eliqinile lokulwa nokuphazamiseka nokusebenza komkhiqizo okuzinzile nokuthembekile.
Imbobo yocingo
I-MDLR311 inikeza izinhlobo ezimbili zesixhumi esibonakalayo samandla, izinhlobo ezimbili zesixhumi esibonakalayo samandla zingakhetha eyodwa kuphela ezizosetshenziswa, azikwazi ukuxhunywa ngesikhathi esisodwa.
I-Vin+ GND: Ibanga lamandla kagesi lalesi sikhombimsebenzisi yi-DC 5 ~ 30V;
I-BAT+ BAT-: Ububanzi bamandla kagesi walesi sikhombimsebenzisi ngu-3.4~4.2V.
Imbobo ye-serial
I-RS232 (RXD, TXD, GND) kanye ne-interface ye-485 imakwe kuphaneli, futhi eyodwa kuphela yazo engakhethwa;
Uma isetshenziswa ngesikhathi esifanayo, kuyadingeka ukuqinisekisa ukuthi izimbobo ezimbili ze-serial zeI-RTUziyagxaza ngesikhathi sedatha yembobo yesiriyeli, ngaphandle kwalokho kuzoba nezingxabano.
Umkhiqizo wochungechunge lwe-MDL wamukela i-32-bit ARM yamandla aphansi we-CPU, kanye nobuchwepheshe bokuxhumana be-RF obuhlukile bobuchwepheshe be-Mind, okwenza umkhiqizo olindile ube ngaphansi kuka-50uA.
Ekusetshenzisweni kwamandla okungu-50uA, idivayisi ye-MDL isesesimweni sokusebenza futhi ingathola futhi ithumele idatha noma nini, okungekona ukusetshenziswa kwamandla lapho ulele.
*Yonke idatha engenhla ikalwa “ngemodi yokubalulekile kwamandla”.
Inethiwekhi ye-AD-hoc eguquguqukayo nenamandla
Ukuxhumana kokusakaza
Kunethiwekhi efanayo, idivayisi ngayinye ixhumana nenye.
Ukuxhumana kwephuzu
Kunethiwekhi efanayo, ukuxhumana kwephoyinti phakathi kwanoma yiziphi izisetshenziswa ezimbili kungenziwa.
Ukuxhumana kokusakaza okuningi
Kunethiwekhi efanayo, idivayisi eyodwa noma eziningi zingasethwa njengeqembu ukuze kubonakale ukuxhumana phakathi kwamaqembu
*Izindlela ezintathu zokuxhumana ezingenhla zingahlanganiswa kunethiwekhi efanayo.
*I-MDLR311 coordination 4G RTU ingasetha kalula isango le-LoRa futhi ibone ukudluliswa kwedatha okukude.
Ngokungeziwe ekusebenziseni umugqa wembobo we-serial wasendaweni ukuze ulungiselele amapharamitha ngokuqondile, okokusebenza kwe-Mind LoRa futhi kusekela ukumiswa okungenantambo kwamapharamitha wedivayisi ekude.
Njengoba kuboniswe emfanekisweni ongenhla:
Idivayisi A ixhunywe kukhompuyutha ngekhebula lembobo ye-serial. Ngokusebenzisa isofthiwe yokumisa imifanekiso ehlinzekwe inkampani yethu, imingcele yedivayisi yasendaweni a ingacushwa kalula nangokushesha, futhi imingcele yedivayisi ekude B ingalungiselelwa inethiwekhi engenantambo.
*Ukuze ulungiselele amapharamitha kumodi engenantambo, kubalulekile ukuqinisekisa ukuthi idivayisi yasendaweni kanye nesilawuli kude kunethiwekhi efanayo.
