diplomsko delo
Abstract
Naloga diplomske naloge je bila načrtovanje, izvedba in ovrednotenje merilnega sistema, ki
vključuje komercialno EEG napravo in je namenjena promociji znanosti.
Diplomsko delo bo obsegalo osnovno merjenje električnih veličin človeških možganov. S
pomočjo merilnega stolpa, v katerem bo žogica, bom prikazal raven pozornosti in
sproščenosti in prikazal izmerjeno aktivnost človeških možganov.
Iz signala EEG merilnika lahko razberemo, ali je oseba sproščena ali fokusirana. To je
odvisno od frekvence napetosti v EEG signalu. Oba podatka signala potujeta na bluetooth
modul, ki je povezan na Arduino Nano krmilnik. Le-ta surove podatke obdela in jih naprej
pošlje na ventilator. Krmilnik ima nalogo, da krmili hitrost vrtenja vetrnice, ki bo ustvarila
nadtlak v merilnem stolpu. Na gred motorja je pritrjena vetrnica, ki piš zraka vodi
skozi merilni stolp in na izhodu stolpa ustvari laminarni zračni tok. Zaradi različnih presekov
se spremeni hitrost vetra, na vrhu stolpa pa se pojavi laminaren tok, zaradi katerega bo žogica
stabilno lebdela nad njim.
Ko bodo možgani bolj skoncentrirani, bo aplikacija motor zagnala hitreje, posledica tega pa
bo, da se bo tudi žogica premaknila višje. Ko bodo možgani manj skoncentrirani, bo žogica
nižje.

Secondary title: |
Control of ball levitation by means of electroencephalography |
Secondary abstract: |
The dissertation was designed, implemented and exclusively a measurement system that includes a
commercial EEG device and is intended to promote science.
The thesis will include basic measurement of electrical quantities of the human brain. With the help
of a measuring tower in which the ball will be, I will show the level of attention and relaxation and
show the measured activity of the human brain.
From the EEG signal, we can tell if a person is relaxed or focused. This is required from the voltage
frequency in the EEG signal. Both data signals are predicted by a bluetooth module connected to the
Arduino Nano controller. It processes the raw data and then sends it to the fan. The controller has
the task of controlling the speed of rotation of the windmill, which will create overpressure in the
measuring tower. A windmill is attached to the motor shaft, which blows air through the measuring
tower and creates a laminar air flow at the exit of the tower. Due to the different cross-sections, the
wind speed changes, and a laminar current appears at the top of the tower, which will cause the ball
to float stably above it.
As the brain becomes more concentrated, the motor application will start faster, and as a result, the
ball will also move higher. When the brain is less concentrated, the ball will be lower. |
