Prenos podatkov z ultrazvokom

Malovrh, Jure (avtor), Marolt, Matija (mentor)

V pričujočem delu se ukvarjamo s področjem prenosa podatkov preko neslišnih frekvenc. V ta namen smo razvili Android aplikacijo, ki je namenjena pošiljanju in prejemanju zvoka. Za namen testiranja prenosa podatkov smo razvili tri različne načine prenosa, ki smo jih med seboj natančno primerjali. Naš cilj je bil prenos 32 bitov v času od dveh do treh sekund. Vsako metodo smo predstavili z več podmetodami, ki so se med seboj razlikovale v hitrosti prenosa. Na ta način smo med njimi prikazali odvisnost med hitrostjo prenosa in natančnostjo prejemanja. Cilj smo uspešno dosegli z vsemi tremi metodami.

Izvleček

In our work we are focusing on data transmission via inaudible frequencies. For this we have developed an Android application that is designed to send and receive sound. For the purpose of transmission tests we have developed three distinct methods of transmission, which have been compared to each other. In our tests we took into account several criteria, among which we wanted to find correlations. Our goal is the transfer of 32 bits in the shortest time possible. Each method was presented with several submethods, which differed in the speed of transmission. With submethods we show the correlation between transmission speed and precision of receiving. We were successful in achieving our goal with all of the methods.
