20.500.12556/DKUM-95321 Razvoj platforme za brezkontaktno detekcijo in nadzor pene v bioreaktorjih magistrsko delo Development of a platform for contactless foam detection and control in bioreactors V magistrski nalogi je predstavljen celovit razvoj platforme za brezkontaktno detekcijo in nadzor pene v bioreaktorjih, ki združuje sodobne senzorske tehnologije ter napredne pristope avtomatizacije. Osrednji cilj raziskave je bil doseči natančno in zanesljivo spremljanje nastajanja pene brez neposrednega stika z medijem ter hkrati zagotoviti možnost avtomatskega doziranja protipenilnih sredstev. V teoretičnem delu so analizirani fizikalno-kemijski mehanizmi nastajanja pene ter opisane ključne funkcije bioreaktorjev, ki vplivajo na stabilnost procesov. Eksperimentalni del zajema primerjavo več pristopov, med katerimi izstopajo optična detekcija z uporabo Beckhoff Vision sistema, uporaba IR osvetlitve in transparentnih grelcev za odpravo kondenza ter integracija radarskih senzorjev (Keyence, Endress+Hauser) za robustno spremljanje nivoja pene in tekočine. Rezultati testiranj potrjujejo, da so radarske metode zaradi odpornosti na kondenz in motnje posebej primerne za industrijsko okolje, medtem ko računalniški vid omogoča visoko natančnost ob ustreznih svetlobnih pogojih. Zaključni del naloge zajema implementacijo demo stroja, programiranega v okolju TIA Portal, s celostnim uporabniškim vmesnikom na HMI panelu, kar omogoča intuitivno upravljanje in enostavno integracijo v širše procesne sisteme. Razvita platforma tako pomembno prispeva k izboljšanju učinkovitosti in zanesljivosti bioprocesov ter predstavlja osnovo za nadaljnje raziskave na področju inteligentne avtomatizacije biotehnoloških aplikacij. The master’s thesis presents the comprehensive development of a platform for contactless foam detection and control in bioreactors, combining modern sensor technologies with advanced automation approaches. The main objective of the research was to achieve accurate and reliable monitoring of foam formation without direct contact with the medium, while simultaneously providing the possibility of automatic dosing of antifoaming agents. The theoretical part analyzes the physico-chemical mechanisms of foam formation and describes the key functions of bioreactors that influence process stability. The experimental part includes a comparison of several approaches, among which stand out optical detection using the Beckhoff Vision system, the use of IR illumination and transparent heaters to eliminate condensation, and the integration of radar sensors (Keyence, Endress+Hauser) for robust monitoring of foam and liquid levels. The test results confirm that radar methods, due to their resistance to condensation and disturbances, are particularly suitable for industrial environments, while computer vision enables high accuracy under appropriate lighting conditions. The final part of the thesis covers the implementation of a demo machine, programmed in the TIA Portal environment, with a comprehensive user interface on an HMI panel, which allows intuitive operation and easy integration into broader process systems. The developed platform thus significantly contributes to improving the efficiency and reliability of bioprocesses and represents a foundation for further research in the field of intelligent automation of biotechnological applications. razvoj brezkontaktna detekcija funkcionalnost pena bioreaktor development non-contact detection functionality foam bioreactor true true false [N.
