20.500.12556/RUL-150258 Sledenje predmetom z moduli LoRa Object tracking with LoRa modules Predstavili bomo poskus izdelave sistema za sledenje objektov z uporabo modula LoRa SX1280. Ta temelji na štirih enotah: treh oddajnikih in enem sprejemniku. S poznavanjem razdalj med sprejemnikom in posameznim oddajnikom ter med seboj relativnimi lokacijami oddajnikov lahko s pomočjo trilateracije izračunamo lokacijo sprejemnika. Opišemo sestavljanje enot, modifikacijo modulov z dodajanjem zunanje antene in delovanje programske kode našega sistema po komponentah. Nazadnje predstavimo rezultate poskusa našega sistema na dveh terenskih testih. Najprej izvedemo meritev med dvema enotama, torej merimo zgolj razdaljo, nato pa vpeljemo še dve enoti in izvedemo trilateracijo. In the following text, we present our attempt to develop an object-tracking system based on the LoRa SX1280 module. The foundation of our system are four units: three transmitters and one receiver. With the knowledge of the distance between the receiver and the individual transmitters, as well as the transmitters' relative positions, we can discern the receiver's position using trilateration. We describe the assembly of the units, the process of installing an external antenna onto the LoRa modules and the workings of our system's code by components. Finally, we detail the results obtained from our system during two field tests. The first is a preliminary ranging test with two units, and the second is a full test of the proposed system with trilateration. sledenje LoRa merjenje razdalje trilateracija tracking LoRa ranging trilateration true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2023-09-15 10:05:00 2023-09-15 10:05:01 2023-10-18 13:31:44 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 36733 168945667 Oberstar_Zan_-_Sledenje_predmetom_z_moduli_LoRa.pdf Oberstar_Zan_-_Sledenje_predmetom_z_moduli_LoRa.pdf 1 B3DE467B328D3DB026A33AD1E2B71213 1c214fb9d12a25fbceaca37482b817852f53866833060249f6d9350f703a72e3 92a99783-539e-11ee-9ef6-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=174824 Fakulteta za računalništvo in informatiko 0 0 0
