• Kutumiza mowonekera kwa serial data
• 50uA kugwiritsa ntchito mphamvu zochepa
• 3-8km kulumikizana mtunda
• Njira zingapo zolumikizirana pamaneti

M'machitidwe atatu omwe ali pamwambawa, MDL311 ikhoza kutumiza ndi kulandira deta, ndipo magawo omwe atchulidwa pamwambapa ndi deta yoyesedwa.

Ukadaulo wa LoRa uli ndi mphamvu ya recei yayikulu (RSSI) ndi chiŵerengero cha ma sign-to-noise (SNR), kuphatikizidwa ndi ukadaulo wathu wosinthira komanso ukadaulo wotsitsa, LoRa opanda zingwe ali ndi mphamvu zotsutsana ndi kusokoneza komanso magwiridwe antchito okhazikika komanso odalirika.

Wiring port

MDL311 imapereka mitundu iwiri ya mawonekedwe amphamvu, mitundu iwiri ya mawonekedwe amagetsi amatha kusankha imodzi yogwiritsira ntchito, sangathe kulumikizidwa nthawi imodzi.

Vin + GND: Mphamvu yamagetsi yamagetsi ya mawonekedwe awa ndi DC 5 ~ 30V;

BAT + BAT-: Mphamvu yamagetsi yamagetsi ya mawonekedwe awa ndi 3.4 ~ 4.2V.

Seri Port

RS232 (RXD, TXD, GND) ndi mawonekedwe a 485 amalembedwa pagawo, ndipo m'modzi yekha wa iwo angasankhidwe;

Ngati ikugwiritsidwa ntchito nthawi yomweyo, ndikofunikira kuwonetsetsa kuti madoko awiri a DTU akugwedezeka panthawi ya data ya recei serial port, apo ayi padzakhala mikangano.

Zogulitsa za MDL zimatenga 32-bit ARM low-power CPU, komanso ukadaulo wapadera waukadaulo wa RF waukadaulo wa Mind, womwe umapangitsa kuti zinthuzo zikhale zocheperako kuposa 50uA.

Pogwiritsa ntchito mphamvu ya 50uA, chipangizo cha MDL chikadali chogwira ntchito ndipo chimatha kulandira ndi kutumiza deta nthawi iliyonse, yomwe siigwiritsa ntchito mphamvu pogona.

*Zida zonse zomwe zili pamwambazi zimayesedwa mu "power priority mode".

Network yosinthika komanso yamphamvu ya AD-hoc

Kulankhulana pawayilesi

Mu maukonde omwewo, chipangizo chilichonse chimalumikizana.

Kulankhulana mfundo

Mu maukonde omwewo, kulumikizana kwa mfundo pakati pa zida ziwiri zilizonse kumatha kuchitika.

Multicast kulumikizana

Mumanetiweki omwewo, zida imodzi kapena zingapo zitha kukhazikitsidwa ngati gulu kuti zizindikire kulumikizana pakati pamagulu

*Njira zitatu zomwe zili pamwambazi zitha kuphatikizidwa mumanetiweki omwewo.

*MDL311 coordination 4G DTU imatha kukhazikitsa LoRa pachipata ndikuzindikira kufalikira kwakutali.

Kuphatikiza pa kugwiritsa ntchito mzere wa doko la serial kuti musinthe magawo mwachindunji, zida za Mind LoRa zimathandiziranso kusinthidwa kwa waya kwa magawo akutali.

Monga momwe tawonetsera pa chithunzi pamwambapa:

Chipangizo A chimalumikizidwa ndi kompyuta kudzera pa chingwe cha serial port. Pogwiritsa ntchito pulogalamu yosinthira zithunzi zoperekedwa ndi kampani yathu, magawo a chipangizo cham'deralo a amatha kukhazikitsidwa mosavuta komanso mwachangu, ndipo magawo a chipangizo chakutali B amathanso kukhazikitsidwa ndi netiweki yopanda zingwe.

*Kukonza magawo mumayendedwe opanda zingwe, ndikofunikira kuwonetsetsa kuti chipangizo chapafupi ndi chida chakutali zili pamanetiweki omwewo.
