  • Gudbinta hufan ee xogta taxanaha ah
  • 50uA isticmaalka tamarta hoose
  • 3-8km fogaan isgaarsiineed
  • Hababka isgaadhsiinta shabakadaha badan

Saddexda hab ee kor ku xusan, MDL311 waxay soo diri kartaa oo heli kartaa xogta, iyo cabbirrada kor lagu soo sheegay waa xog la qiyaasay.

Tiknoolajiyada LoRa waxay leedahay dareen-celin sare (RSSI) iyo saamiga signal-to-coise (SNR), oo ay weheliso hab-nololeedkayada gaarka ah iyo tignoolajiyada demodulation, badeecada LoRa wireless waxay leedahay awood xoog leh oo ka-hortagga faragelinta iyo waxqabadka badeecada xasilloon oo la isku halayn karo.

Xadhkaha goosashada

MDL311 waxay bixisaa laba nooc oo is dhexgal awoodeed ah, laba nooc oo is dhexgal awoodeed ah ayaa dooran kara mid keliya oo la isticmaalo, isku mar lama xidhi karo.

Vin+ GND: Kala duwanaanshaha korantada korantada ee interface-kan waa DC 5 ~ 30V;

BAT + BAT-: Kala duwanaanshaha korantada korantada ee interface-kan waa 3.4 ~ 4.2V.

Deked Taxane ah

RS232 (RXD, TXD, GND) iyo 485 interface ayaa lagu calaamadeeyay guddiga, oo mid kaliya ayaa la dooran karaa;

Haddii isku mar la isticmaalo, waxaa lagama maarmaan ah in la hubiyo in laba dekedood oo taxane ah oo DTU ah ay is-daba-joogaan wakhtiga xogta dekedda ee rasiidhka ah, haddii kale waxaa jiri doona khilaaf.

Badeecada taxanaha MDL waxay qabataa 32-bit ARM awood hoose CPU, iyo tignoolajiyada gaarka ah ee isgaarsiinta RF ee tignoolajiyada Maskaxda, taas oo ka dhigaysa sheyga diyaarsanaanta hadda wax ka yar 50uA.

Isticmaalka korantada 50uA, qalabka MDL ayaa wali ku jira xaalada shaqada wuxuuna heli karaa oo soo diri karaa xogta wakhti kasta, taas oo aan ahayn isticmaalka tamarta ee hurdada.

* Xogta kore oo dhan waxaa lagu cabbiraa "qaabka mudnaanta awoodda".

Shabakadda AD-hoc dabacsan oo awood badan

Baahinta isgaarsiinta

Isla shabakadda, qalab kastaa wuxuu la xiriiraa midba midka kale.

Xidhiidhka-point-point

Isla shabakad isku mid ah, isgaadhsiinta bar-tilmaameedka ee u dhexeeya laba qalab ayaa la xaqiijin karaa.

Isgaarsiinta Multicast

Isla shabakad isku mid ah, hal ama dhowr qalab ayaa loo dejin karaa koox ahaan si loo xaqiijiyo xidhiidhka ka dhexeeya kooxaha

*Saddexda hab ee kor ku xusan waxaa lagu dari karaa shabakad isku mid ah.

* Isuduwidda MDL311 4G DTU waxay si fudud u dejin kartaa gateway LoRa waxayna xaqiijin kartaa gudbinta xogta fog.

Marka laga soo tago adeegsiga xariiqda dekeda taxan ee maxalliga ah si loo habeeyo cabbirrada si toos ah, Qalabka Mind LoRa wuxuu kaloo taageeraa qaabeynta wireless-ka ee cabbirrada aaladaha fog.

Sida ka muuqata sawirka kore:

Aaladda A waxa ay ku xidhan tahay kombayutarka iyada oo loo marayo fiilada dekedaha ee serial. Isticmaalka software qaabeynta garaafyada ay bixiso shirkadeena, xuduudaha aaladaha maxalliga ah a waxaa loo habeyn karaa si ku habboon oo degdeg ah, iyo cabbirrada aaladda fog B waxaa sidoo kale lagu habeyn karaa shabakadda wireless-ka.

* Si loo habeeyo cabirrada habka wireless-ka, waxaa lagama maarmaan ah in la hubiyo in aaladda maxalliga ah iyo aaladda fog ay ku jiraan isku shabakad.
