Koncept využití VLC technologie v průmyslovém prostředí

Abstract

This diploma thesis deals with the topic of VLC (Visible Light Communication) technology and its application in an industrial environment. The theoretical part of the thesis focuses on the current state of wireless and wired communication in industry, a description of VLC technology, and various types of VLC signal modulation. It also includes previous experiments that dealt with visible light communication. The practical part focuses on measuring the bit error rate (BER) of a VLC system implemented in the KUKA ready2_educate educational platform. While the transmitting LED element was placed in one or more positions across the enclosure, the receiving photodetector was mounted directly onto the KUKA KR 4 AGILUS robot. Two scenarios were measured. In the first, the photodetector had a fixed position, and the robot was illuminated by a single LED module placed in the upper part of the enclosure. In the second part, 6 LED modules were used, which were dynamically switched on and off during the experiment, and the photodetector holder had an angle adjustable in 15° increments.
