This bachelor's thesis deals with the design and implementation of signal preprocessing methods for an industrial fluidized bed equipped with an AI gateway module. The work focuses on the processing of image, vibration, and acoustic data obtained from the fluidization process for the purpose of operating state identification and anomaly detection. The theoretical part covers the principles of fluidization, measurement techniques for fluidized bed characterization, and selected neural network architectures applicable to signal and image processing. Particular attention is devoted to convolutional neural networks, autoencoders, and Higher-Order Neural Units (HONU). The practical part includes the design of the hardware and software architecture of the AI gateway, implementation of communication interfaces, and development of algorithms for data processing and analysis. An autoencoder-based approach was employed for anomaly detection in image data, while the HONU architecture was utilized for approximation and modeling of the dynamics of the monitored processes. Due to the delayed delivery of real industrial data by VM Engineering s.r.o., validation of the proposed methods on operational data could not be performed. Therefore, synthetic datasets and signals simulating the characteristics of the monitored process were generated and used to demonstrate the functionality of the developed systems. The obtained results confirm the functionality of the proposed solution and demonstrate the potential of artificial intelligence methods for monitoring, identification, and diagnostics of industrial fluidized bed processes.
