-139dbm high receiver sensitivity data transmission ophatikizidwa LoRa DTU module
The LORA DTU module_MDL210 embedded terminal ndi yomwe imagwiritsa ntchito ukadaulo wa LoRa spread spectrum potumiza ma data opanda zingwe, kupatsa ogwiritsa ntchito njira yopatsira deta yopanda ma protocol yowonekera bwino.Mukungofunika kukhazikitsa magawo osavuta kuti mukwaniritse mitundu ingapo ya maukonde monga star networking ndi Mesh network. Palinso mitundu ingapo yolankhulirana monga pakufunidwa, kuwulutsa, ndi ma multicast mu netiweki yomweyo;
Mawonekedwe olumikizirana a TTL amaperekedwa, maukonde ogwiritsira ntchito makina ogwiritsira ntchito ma serial port, zida zamagetsi zimatengera kapangidwe kake kogwiritsa ntchito mphamvu zochepa (≤40uA@5V).
Tekinoloje ya LoRa palokha ili ndi chidwi chachikulu cha recei (RSSI) komanso
super signal-to-noise (SNR) kuphatikiza luso lathu lothandizira la modemu komanso magwiridwe antchito okhazikika komanso odalirika.
Module yopanda zingwe ya LoRa ili ndi mphamvu zotsutsana ndi kusokoneza.
MDL210 imagwirizana ndi 4G DTU ya kampani yathu, yomwe ingathandize kukhazikitsidwa kwa LoRa gateway kuti izindikire kutumizira kwakutali.
Kulankhulana pawayilesi
Pansi pa netiweki yomweyo, chipangizo chilichonse chimalumikizana ndi mnzake
Kulankhulana - mfundo
Pansi pa maukonde omwewo, kulumikizana kwa mfundo
pakati pa zida ziwiri zilizonse zitha kuzindikirika
Multicast kulumikizana
Pansi pa netiweki yomweyi, zida imodzi kapena zingapo zitha kukhazikitsidwa ngati gulu kuti zikwaniritse kulumikizana kwamagulu
Njira zitatu zomwe zili pamwambazi zitha kuphatikizidwa mumaneti omwewo
Kuphatikiza pakugwiritsa ntchito chingwe cham'deralo kuti musinthe magawo a chipangizo cha MIND LoRa,imathandizanso opanda zingwekukonza magawo a chipangizo chakutali.
Monga zikuwonetsedwa mu FIG:
Chipangizocho chimalumikizidwa ndi kompyuta kudzera pa chingwe cha serial, ndipo pulogalamu yosinthira zithunzi yomwe kampani yathu ikupereka ingagwiritsidwe ntchito kukonza magawo a chipangizo cham'deralo A mosavuta komanso mwachangu, ndipo magawo a chipangizo chakutali B amathanso kukhazikitsidwa. opanda zingwe.
*Kuti musinthe ma parameter mumayendedwe opanda zingwe, onetsetsani kuti chipangizo chapafupi ndi chakutali zili pamanetiweki omwewo

Kuyambira 2015, kampani yathu yayamba kupanga ndi kupanga zinthu zingapo za LoRa, ndikutumiza kopitilira mayunitsi opitilira 5,000. Zaka ziwiri zapitazi, zogulitsa za LoRa zakhala zikugwiritsidwa ntchito bwino ku "National Mountain Flood Disaster Early Warning" pulojekiti yomwe kampani yathu idatenga nawo gawo. Zowona zatsimikizira kuti ife Ndi mawonekedwe ake apamwamba, okhazikika, komanso otsimikizika kwambiri. makhalidwe, mankhwala ake akhala anazindikira mu makampani ndi kukhala ndi mbiri yabwino pakati makasitomala.
