-139dbm mkulu wolandila chidziwitso cha data kufalaophatikizidwaLoRa DTU gawo

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 chipata cha LoRa kuti chizindikire kufalitsa 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:

Chipangizo A chimalumikizidwa ndi kompyuta kudzera pa chingwe cha serial, ndipo pulogalamu yosinthira zithunzi yoperekedwa ndi kampani yathu ingagwiritsidwe ntchito kukonza magawo a chipangizo cham'deralo A mosavuta komanso mwachangu, ndipo magawo a chipangizo chakutali B amathanso kukhazikitsidwa popanda 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. M'zaka ziwiri zapitazi, zinthu zamtundu wa LoRa zakhala zikugwiritsidwa ntchito bwino ku "National Mountain Flood Disaster Early Warning" pulojekiti yomwe kampani yathu yachita nawo. Zowona zatsimikizira kuti ife Ndi makhalidwe ake apamwamba, okhazikika, komanso odalirika kwambiri, zogulitsa zake zakhala zikudziwika mu malonda ndipo zimakhala ndi mbiri yabwino pakati pa makasitomala.
