Aplikace IoT senzoru napájeného termoelektrickým generátorem na demonstrační výrobní lince

Abstract

This bachelor thesis focuses on the issue of energy autonomy for IoT sensor nodes in industrial environments within the Industry 4.0 framework. The primary focus is on utilizing waste heat from electric motors to power wireless vibration monitoring units, thereby eliminating the need for regular battery maintenance or costly power cabling installations. The entire project integrates principles of thermal energy harvesting using thermoelectric generators, low-power embedded system design, and the LoRaWAN wireless communication standard. As part of the solution, a functional sample of the IoT node was designed and implemented, featuring an efficient power chain and an asynchronous algorithm for detecting and processing mechanical vibrations. The proposed system was verified through practical tests on the Smart Factory demonstration production line using a Bosch Rexroth motor, where the diagnostic functionality was validated and the system's energy balance was analyzed, identifying the essential requirements for achieving full energy neutrality in the future.
