• Ukudluliswa kwedatha elandelanayo okusobala
• Ukusetshenziswa kwamandla okuphansi okungu-50uA
• Ibanga lokuxhumana elingamakhilomitha angu-3-8
• Izindlela zokuxhumana zenethiwekhi eziningi

Kulezi zindlela ezintathu zokusebenza ezingenhla, i-MDL311 ingathumela futhi yamukele idatha, futhi amapharamitha ashiwo ngenhla ayidatha elinganisiwe.

Ubuchwepheshe be-LoRa bunokuzwela okuphezulu kokwamukela (i-RSSI) kanye nesilinganiso sesignali kuya komsindo (i-SNR), kanye nobuchwepheshe bethu bokuguqulwa kokuguquguquka kanye nokwehliswa komsindo, umkhiqizo ongenantambo we-LoRa unekhono eliqinile lokulwa nokuphazamiseka kanye nokusebenza komkhiqizo okuzinzile nokuthembekile.

Imbobo yokuxhuma izintambo

I-MDL311 inikeza izinhlobo ezimbili zesikhombimsebenzisi samandla, izinhlobo ezimbili zesikhombimsebenzisi samandla zingakhetha esisodwa kuphela esizosetshenziswa, azikwazi ukuxhunywa ngesikhathi esisodwa.

I-Vin+ GND: Ububanzi be-voltage yokunikezwa kwamandla kwalesi sixhumi esibonakalayo yi-DC 5 ~ 30V;

I-BAT+ BAT-: Ububanzi be-voltage yokunikezwa kwamandla kwalesi sixhumi esibonakalayo bungu-3.4~4.2V.

Imbobo Ehlanganisiwe

I-RS232 (RXD, TXD, GND) kanye ne-interface engu-485 zimakwe kuphaneli, futhi eyodwa kuphela yazo engakhetha;

Uma isetshenziswa ngesikhathi esifanayo, kubalulekile ukuqinisekisa ukuthi amachweba amabili e-DTU alandelanayo ahlukaniswe ngesikhathi sedatha yechweba le-receiving, ngaphandle kwalokho kuzoba nezingxabano.

Umkhiqizo wochungechunge lwe-MDL usebenzisa i-CPU enamandla aphansi angu-32-bit ARM, kanye nobuchwepheshe bokuxhumana be-RF obuhlukile bobuchwepheshe be-Mind, okwenza ugesi womkhiqizo olindile ube ngaphansi kwama-50uA.

Ekusetshenzisweni kwamandla okungu-50uA, idivayisi ye-MDL isesesimeni sokusebenza futhi ingathola futhi ithumele idatha nganoma yisiphi isikhathi, okungesona ukusetshenziswa kwamandla okulele.

*Idatha yonke engenhla ilinganiswa "ngemodi yokubeka phambili amandla".

Inethiwekhi ye-AD-hoc eguquguqukayo nenamandla

Ukuxhumana kokusakaza

Kunethiwekhi efanayo, idivayisi ngayinye iyaxhumana.

Ukuxhumana ngephuzu elilodwa

Kunethiwekhi efanayo, ukuxhumana okuqondile phakathi kwanoma yimaphi amadivayisi amabili kungabonakala.

Ukuxhumana kwe-Multicast

Kunethiwekhi efanayo, amadivayisi owodwa noma amaningi angasethwa njengeqembu ukuze kufezwe ukuxhumana phakathi kwamaqembu

*Izindlela ezintathu zokuxhumana ezingenhla zingahlanganiswa kunethiwekhi efanayo.

*Ukuxhumana kwe-MDL311 4G DTU kungakwazi ukusetha kalula isango le-LoRa futhi kufeze ukudluliswa kwedatha okude.

Ngaphezu kokusebenzisa umugqa we-serial port wendawo ukuze ulungiselele amapharamitha ngqo, imishini ye-Mind LoRa isekela nokucushwa okungenantambo kwamapharamitha edivayisi ekude.

Njengoba kuboniswe esithombeni esingenhla:

Idivayisi A ixhunywe kwikhompyutha ngekhebula le-serial port. Sisebenzisa isofthiwe yokucushwa kwezithombe enikezwe yinkampani yethu, amapharamitha edivayisi yendawo u-a angalungiswa kalula nangokushesha, kanti amapharamitha edivayisi ekude u-B angalungiswa futhi yinethiwekhi engenantambo.

*Ukuze ulungiselele amapharamitha kwimodi engenantambo, kubalulekile ukuqinisekisa ukuthi idivayisi yendawo kanye nedivayisi ekude zikunethiwekhi efanayo.
