Využití bezdrátové technologie Bluetooth pro distribuovaný měřicí systém

Abstract

The goal of this work is to design a distributed measurement system based on Bluetooth technology. Entering the job was designing an appropriate system for measuring student contest organized in support of pre-university education and open days. Distributed modules for the various competition sites contain LCD display unit, push-button controls for the verification of data organizer, Bluetooth Smart and RFID reader module. The control module is based on the platform Raspberry Pi script written in Python. Bluetooth LE is used to ensure communication between individual modules. System of indication is used to collect data from distributed modules. Data are processed in the central module, Raspberry Pi. For authentication and authorization of participants are used RFID smart cards. This device will replace the existing outdated system, while maintaining compatibility with its visualization components, web pages and database system. The proposed system should represent the school before its potential students from secondary schools, and therefore contains elements with modern technology automation.
