• ʻO ka hoʻoili ʻana o ka ʻikepili serial
• 50uA haʻahaʻa mana hoʻohana
• 3-8km mamao kamaʻilio
• Nui nā ʻano kamaʻilio pūnaewele

Ma nā ʻano hana hana ʻekolu i luna, hiki i ka MDL311 ke hoʻouna a loaʻa i ka ʻikepili, a ʻo nā ʻāpana i ʻōlelo ʻia ma luna nei he ʻikepili ana.

Loaʻa i ka ʻenehana LoRa ka ʻike kiʻekiʻe loa (RSSI) a me ka ratio signal-to-noise (SNR), i hui pū ʻia me kā mākou modulation proprietary a me ka ʻenehana demodulation, loaʻa i ka huahana uila ʻo LoRa ka mana anti-interference ikaika a paʻa a hilinaʻi hoʻi ka hana huahana.

awa uwea

Hāʻawi ʻo MDL311 i ʻelua ʻano o ka mana mana, ʻelua ʻano o ka mana mana hiki ke koho i hoʻokahi wale nō e hoʻohana ai, ʻaʻole hiki ke hoʻopili ʻia i ka manawa like.

ʻO Vin+ GND: ʻO ka mana o ka mana o kēia kikowaena DC 5 ~ 30V;

BAT+ BAT-: ʻO ka mana o ka mana o kēia kikowaena he 3.4~4.2V.

Awa Serial

RS232 (RXD, TXD, GND) a me 485 interface ua kaha 'ia ma ka panel, a hookahi wale no o lakou ke koho;

Inā hoʻohana ʻia ia i ka manawa like, pono ia e hōʻoia i ʻelua mau awa serial o DTU i ka manawa o ka loaʻa ʻana o ka ʻikepili serial port, i ʻole e loaʻa nā paio.

Hoʻohana ka huahana MDL series i ka 32-bit ARM low-power CPU, a me ka ʻenehana kamaʻilio RF kūʻokoʻa o ka ʻenehana Mind, kahi e hoʻemi ai ka huahana standby ma mua o 50uA.

Ma ka mana 50uA, aia ka MDL i ka hana a hiki ke loaʻa a hoʻouna i ka ʻikepili i kēlā me kēia manawa, ʻaʻole ia ka mana mana ma lalo o ka hiamoe.

*Aia ʻia nā ʻikepili a pau ma luna o ka "mode priority mode".

Pūnaewele AD-hoc hikiwawe a ikaika

Hoʻolaha hoʻolaha

Ma ka pūnaewele like, kamaʻilio kēlā me kēia mea me kekahi.

Kūkākūkā kiko kiko

Ma ka pūnaewele like, hiki ke ʻike ʻia ke kamaʻilio kiko-point ma waena o nā mea hana ʻelua.

Kūkākūkā multicast

I loko o ka pūnaewele hoʻokahi, hiki ke hoʻonohonoho ʻia nā mea hoʻokahi a i ʻole he hui e ʻike i ke kamaʻilio ma waena o nā hui

* Hiki ke hoʻohui ʻia nā ʻano hana ʻoihana ʻekolu i luna ma ka pūnaewele like.

*MDL311 coordination 4G DTU hiki ke hoʻonohonoho maʻalahi i ka ʻīpuka LoRa a ʻike i ka lawe ʻana i ka ʻikepili mamao.

Ma waho aʻe o ka hoʻohana ʻana i ka laina port serial kūloko e hoʻonohonoho pololei i nā ʻāpana, kākoʻo pū nā lako Mind LoRa i ka hoʻonohonoho uila o nā ʻāpana mamao.

E like me ka mea i hōʻike ʻia ma ke kiʻi ma luna:

Hoʻopili ʻia ka mea hana A i ke kamepiula ma o ke kaula port serial. Ke hoʻohana nei i ka polokalamu hoʻonohonoho kiʻi kiʻi i hāʻawi ʻia e kā mākou hui, hiki ke hoʻonohonoho pono ʻia nā ʻāpana o ka mea kūloko a me ka wikiwiki, a hiki ke hoʻonohonoho ʻia nā ʻāpana o ka mea mamao B e ka pūnaewele uea.

* No ka hoʻonohonoho ʻana i nā ʻāpana ma ke ʻano uila, pono e hōʻoia i ka ʻōnaehana kūloko a me ka mea mamao i ka pūnaewele like.
