• Kutumiza deta yotsatizana mowonekera bwino
• Kugwiritsa ntchito mphamvu zochepa kwa 50uA
• Mtunda wolumikizirana wa 3-8km
• Njira zingapo zolumikizirana pa netiweki

Mu njira zitatu zogwirira ntchito zomwe zili pamwambapa, MDL311 imatha kutumiza ndi kulandira deta, ndipo magawo omwe atchulidwa pamwambapa ndi deta yoyezedwa.

Ukadaulo wa LoRa uli ndi mphamvu yolandira zinthu zambiri (RSSI) komanso chiŵerengero cha ma signal-to-noise (SNR), pamodzi ndi ukadaulo wathu wosinthira ndi kugawa zinthu, chipangizo cha LoRa chopanda zingwe chili ndi mphamvu yolimbana ndi kusokoneza zinthu komanso magwiridwe antchito okhazikika komanso odalirika.

Chipata cholumikizira mawaya

MDL311 imapereka mitundu iwiri ya mawonekedwe amagetsi, mitundu iwiri ya mawonekedwe amagetsi imatha kusankha imodzi yokha yogwiritsira ntchito, ndipo singathe kulumikizidwa nthawi imodzi.

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

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

Doko Lotsatizana

RS232 (RXD, TXD, GND) ndi mawonekedwe a 485 zalembedwa pa gululo, ndipo chimodzi mwa izo ndi chomwe chingasankhidwe;

Ngati ikugwiritsidwa ntchito nthawi imodzi, ndikofunikira kuonetsetsa kuti madoko awiri a DTU a serial asinthidwa nthawi ya data ya serial port, apo ayi padzakhala kusamvana.

Chogulitsa cha MDL chimagwiritsa ntchito CPU ya 32-bit ARM yotsika mphamvu, komanso ukadaulo wapadera wolumikizirana wa RF wa ukadaulo wa Mind, zomwe zimapangitsa kuti mphamvu yamagetsi ya chinthucho ikhale yochepera 50uA.

Pakugwiritsa ntchito mphamvu ya 50uA, chipangizo cha MDL chikugwirabe ntchito ndipo chimatha kulandira ndikutumiza deta nthawi iliyonse, zomwe sizikugwiritsidwa ntchito mphamvu zomwe zili mu tulo.

*Deta yonse yomwe ili pamwambapa imayesedwa mu "power priority mode".

Netiweki ya AD-hoc yosinthasintha komanso yamphamvu

Kulankhulana pa wailesi

Mu netiweki yomweyo, chipangizo chilichonse chimalumikizana.

Kulankhulana kwa mfundo imodzi

Mu netiweki yomweyo, kulumikizana pakati pa zipangizo ziwiri kungatheke.

Kulankhulana kwa ma multicast

Mu netiweki yomweyo, zipangizo chimodzi kapena zingapo zitha kukhazikitsidwa ngati gulu kuti zigwirizane pakati pa magulu

*Njira zitatu zolumikizirana zomwe zili pamwambapa zitha kuphatikizidwa mu netiweki imodzi.

*MDL311 coordination 4G DTU ikhoza kukhazikitsa mosavuta LoRa gateway ndikutha kutumiza deta yakutali.

Kuwonjezera pa kugwiritsa ntchito chingwe cha doko lapafupi kuti mukonze magawo mwachindunji, zida za Mind LoRa zimathandizanso kukonza makonzedwe opanda zingwe a magawo a chipangizo chakutali.

Monga momwe chithunzi chili pamwambapa chikusonyezera:

Chipangizo A chimalumikizidwa ku kompyuta kudzera mu chingwe cha serial port. Pogwiritsa ntchito pulogalamu yosinthira zithunzi yoperekedwa ndi kampani yathu, magawo a chipangizo chapafupi a amatha kukonzedwa mosavuta komanso mwachangu, ndipo magawo a chipangizo chakutali B amathanso kukonzedwa ndi netiweki yopanda zingwe.

*Kuti mukonze magawo mu mawonekedwe opanda waya, ndikofunikira kuonetsetsa kuti chipangizo chapafupi ndi chipangizo chakutali zili mu netiweki yomweyo.
