Abstract

Ovaj rad je dio projekta koji se bavi proučavanjem, snimanjem i obradom EEG signala i signala dobivenim bihevioralnim mjerenjima (analiza video snimke, odnosno pokreta lica ispitanika) te njihovim uspoređivanjem. Rezultati dobiveni EEG mjerenjima koriste se kao referenca za ispitivanje pouzdanosti sustava logiDROWSINE (Xylon d.o.o) koji na temelju analize videa donosi zaključak o umoru ispitanika (vozača automobila).
Primjena sučelja je da sustavu logiRECORDER (Xylon d.o.o) proslijedi podatke iz EEG pojačala koje on sprema u podnaslove video zapisa u kojemu se nalazi snimka vozača. Sučelje je realizirano pomoću mikrokontrolera tvrtke ARM serije STM32F415, odnosno razvojnog sučelja MINI-M4 for STM32.
Na razvojnom sučelju omogućena je obrada dobivenih podataka s EEG pojačala preko serijske veze u stvarnom vremenu te njihovo slanje putem CAN-a prema sustavu logiRECORDER. Smjer komunikacije je obostran, tako da je moguće upravljati postavkama pojačala s logiRECORDER-a. Na sučelje je moguće spojiti dodatni CAN čvor koji prihvaća podatke i serijskom vezom ih šalje prema računalu gdje se oni mogu prikazivati.
Ideja sustava je uspoređivanje signala dobiveni Xylonovom (bihevioralnom) metodom i metodom mjerenja bioelektričnih signala (EEG pojačalo) te njihovo usklađivanje. Tako se može vidjeti i zaključiti kako umor djeluje na motoričke funkcije vozača.
Ovim sustavom bi se mogao smanjiti broj prometnih nesreća izazvanih zbog umora jednom kad se sustav logiDROWSINE implementira u automobile.

Abstract (english)

This thesis is part of the project that deals with studying, recording and processing of EEG signals and signals obtained by behavioural measurements (video analysis, i.e. facial movement analysis), and their comparison. EEG results are used as a reference for the examination of reliability of logiDROWSINE (Xylon d.o.o) system which concludes subject's (driver's) fatigue level based on the video analysis. The interface is utilized in order to transfer data of EEG amplifier to the logiRECORDER (Xylon d.o.o) system. Moreover, the data is saved in subtitles of the video in which the recording of the driver is located. The interface is realised by the microcontroller of the ARM company series STM32F415, that is to say, development board MINI-M4 for STM32. The interface enables real-time data processing obtained from EEG amplifier over the serial link along with their transmission via CAN to the logiRECORDER system. Communication is possible in both directions and thus one may control the settings of the amplifier using logiRECORDER. Furthermore, we can add the additional CAN node which then receives data, and sends it to the computer using the serial link where they can be displayed. The idea of the system is a comparison of signals obtained by Xylon's (behavioural) method and method of measuring the bioelectrical signals (EEG) themselves in order to synchronize them. As a result, it is possible to see and conclude in what way fatigue affects driver's motor functions. This system may reduce the number of traffic accidents caused by fatigue once the logiDROWSINE system is implemnted in cars.
