Advanced signal processing methods for condition monitoring

Condition monitoring of induction motors (IM) among with the predictive maintenance concept are currently among the most promising research topics of manufacturing industry. Production efficiency is an important parameter of every manufacturing plant since it directly influences the final price of products. This research article presents a comprehensive overview of conditional monitoring techniques, along with classification techniques and advanced signal processing techniques. Compared methods are either based on measurement of electrical quantities or nonelectrical quantities that are processed by advanced signal processing techniques. This article briefly compares individual techniques and summarize results achieved by different research teams. Our own testbed is briefly introduced in the discussion section along with plans for future dataset creation. According to the comparison, Wavelet Transform (WT) along with Empirical Mode Decomposition (EMD), Principal Component Analysis (PCA) and Park's Vector Approach (PVA) provides the most interesting results for real deployment and could be used for future experiments.Web of Scienc

The Renovations of Assessment Function Surface Rock Mills

Import 03/08/2012Tématem této bakalářské práce je posoudit možnosti renovace opotřebených dílů a součástí skalní frézy BOART LONGYEAR BF-300 D5, která se používá mimo jiné i v hutním průmyslu k opravě žárobetonových částí hutních pecí. Během pracovní činnosti tohoto zařízení dochází k velkému opotřebení pracovních nožů RM5. Aby se nesnížila produktivita celého procesu frézování, musí se tyto opotřebené nože často měnit za nové a ty použité se ve stávající praxi vyhazují, což se z ekonomického hlediska značně prodraží. Cílem této práce je zvolit vhodnou technologii k renovaci opotřebených nožů skalní frézy a finanční náklady vynaložené na renovaci těchto dílů efektivně zhodnotit.The Theme of this Bachelor Thesis is the assessment of renovation possibilities of worn down components of the Rock Mill BOART LONGYEAR BF-300 D5 which is used besides other things also in the metallurgical industry to repairing of concrete components of furnace. It comes up to wear down of working blades RM5 in the course of working operations of this facilities. Not to reduce productivity of the whole milling process, worn down blades must be replaced with new blades one by one, they are in practice discarded which increase the cost from the economic point of view. The main object of this Thesis is to choose a right technology for a renovation of worn down blades of the Rock Mill and to evaluate effectively the financial cost expended on renovation of these components.345 - Katedra mechanické technologievýborn

Human activity classification using multilayer perceptron

The number of smart homes is rapidly increasing. Smart homes typically feature functions such as voice-activated functions, automation, monitoring, and tracking events. Besides comfort and convenience, the integration of smart home functionality with data processing methods can provide valuable information about the well-being of the smart home residence. This study is aimed at taking the data analysis within smart homes beyond occupancy monitoring and fall detection. This work uses a multilayer perceptron neural network to recognize multiple human activities from wrist- and ankle-worn devices. The developed models show very high recognition accuracy across all activity classes. The cross-validation results indicate accuracy levels above 98% across all models, and scoring evaluation methods only resulted in an average accuracy reduction of 10%.Web of Science2118art. no. 620

This study deals with the technology of autonomous mobile robots (AMR) and their implementation on the SmartFactory production line at the Technical University of Ostrava. The task of the mobile robot is to cooperate with the production line, take over the manufactured products, and then deliver them. The content also includes a description of the individual steps that were necessary to make the mobile robot operational, such as loading a virtual map of the space, creating a network for communication with the mobile robot, and programming it. The main part of the experiment deals with testing the accuracy of moving the mobile robot to each position and establishing communication between the production line and the mobile robot. A high accuracy is a necessity in this process. The result of the study is the configuration of the autonomous mobile robot. The repetitive precision of the approach of the autonomous mobile robot to a position is +/- 3 mm.Web of Science1217art. no. 891
