Reflexní optoelektrická závora

Abstract

This bachelor thesis deals with design and execution of reflective optoelectronic doorframe bar, which is able to detect and analyse passing object’s direction of movement through the doorframe. Main objective of theoretical part is to acquaint with information about optical radiation, essential features of optical bars and in-depth analysis of optical transmitters and detectors. Practical part is therefore focussed on the design and the execution itself. Electric schemes and printed circuit board schemes of emitting and detection bar parts have been designed using Eagle software. Atmel’s ATMEGA2560 microcontroller was used as the primary signal analysis control unit of the Arduino Mega 2560 platform. Arduino microprocessor was designed using it’s original Wiring processing language for movement direction analysis and subsequently for reflecting the results on computer display unit using serial communication. For operating with serial port was chosen terminal Hercules Setup software.
