• Kohereza mu mucyo amakuru yuruhererekane
• 50uA gukoresha ingufu nke
• Intera y'itumanaho 3-8
• Uburyo bwinshi bwo gutumanaho kumurongo

Muburyo butatu bwo gukora, MDL311 irashobora kohereza no kwakira amakuru, kandi ibipimo byavuzwe haruguru bipimwa amakuru.

Ikoranabuhanga rya LoRa rifite ibyiyumvo byinshi byo kwakirwa (RSSI) hamwe n’ikigereranyo cyerekana urusaku (SNR), hamwe n’ikoranabuhanga ryacu ryo guhinduranya no gukoresha demodulation, ibicuruzwa bidafite umugozi wa LoRa bifite ubushobozi bukomeye bwo kurwanya kwivanga no gukora neza kandi byizewe.

Icyambu

MDL311 itanga ubwoko bubiri bwimbaraga, ubwoko bubiri bwimbaraga zishobora guhitamo imwe yo gukoresha, ntishobora guhuzwa icyarimwe.

Vin + GND: Umuyoboro w'amashanyarazi utanga amashanyarazi ni DC 5 ~ 30V;

BAT + BAT-: Amashanyarazi atanga amashanyarazi ya interineti ni 3.4 ~ 4.2V.

Icyambu

RS232 (RXD, TXD, GND) na 485 Imigaragarire yashyizwe kumurongo, kandi imwe murimwe irashobora guhitamo;

Niba ikoreshwa icyarimwe, birakenewe kwemeza ko ibyambu bibiri byuruhererekane bya DTU bihindagurika mugihe cyo kwakira amakuru yicyambu cya seriveri, bitabaye ibyo hakabaho amakimbirane.

Ibicuruzwa bya MDL bikoresha 32-biti ya ARM ifite ingufu nkeya CPU, hamwe nubuhanga budasanzwe bwitumanaho bwa RF bwikoranabuhanga rya Mind, bigatuma ibicuruzwa bihagarara munsi ya 50uA.

Kuri 50uA ikoresha ingufu, ibikoresho bya MDL biracyari mubikorwa kandi birashobora kwakira no kohereza amakuru umwanya uwariwo wose, ntabwo aribyo gukoresha ingufu mugitotsi.

* Ibisobanuro byose byavuzwe haruguru bipimirwa muri "power priorité mode".

Umuyoboro woroshye kandi ukomeye AD-hoc

Itumanaho

Mumuyoboro umwe, buri gikoresho gishyikirana.

Itumanaho-ngingo

Mumuyoboro umwe, itumanaho-ngingo hagati yibikoresho bibiri birashobora kugerwaho.

Itumanaho ryinshi

Mumuyoboro umwe, ibikoresho kimwe cyangwa byinshi birashobora gushyirwaho nkitsinda kugirango tumenye itumanaho hagati yitsinda

* Uburyo butatu bwo hejuru bwo guhuza bushobora guhuzwa murusobe rumwe.

* Guhuza MDL311 4G DTU irashobora gushiraho byoroshye amarembo ya LoRa no kumenya kohereza amakuru kure.

Usibye gukoresha umurongo wa porte yumurongo kugirango ugene ibipimo bitaziguye, ibikoresho bya Mind LoRa binashyigikira iboneza rya simusiga ryibikoresho bya kure.

Nkuko bigaragara ku gishushanyo kiri hejuru:

Igikoresho A gihujwe na mudasobwa hifashishijwe umugozi wicyambu.Ukoresheje ibishushanyo mbonera byashizweho na sosiyete yacu, ibipimo byibikoresho byaho a birashobora gushyirwaho byoroshye kandi byihuse, kandi ibipimo byigikoresho cya kure B nabyo birashobora gushyirwaho numuyoboro udafite umugozi.

* Kugirango ugaragaze ibipimo muburyo butagikoreshwa, birakenewe kwemeza ko igikoresho cyaho nigikoresho cya kure kiri murusobe rumwe.
