Automatic production line efficiency evaluation and optimization
Štěrba, Zdeněk ; Kaczmarczyk, Václav
The article deals with the analysis of the production line in terms of overall efficiency. The aim is to define the areas that play a role in overall efficiency and then devise appropriate solutions to improve them. Emphasis is placed on the analytical method Basic MOST designed for work norming, according to which the normalized time of operators is determined. The next part of the paper is devoted to the analysis in order to find the weak points of the line that could be optimized in order to increase efficiency or financial savings. The production line and its analysis is also processed as a discrete event system in Siemens Plant Simulation software, focusing on the data flow and variability of the whole system.
AAS interpreter for testbed I4.0
Chmelař, Luboš ; Kaczmarczyk, Václav (referee) ; Baštán, Ondřej (advisor)
This bachelor thesis presents an innovative approach to integrating the Asset Administration Shell (AAS) model into an embedded system that is a key part of the Industry 4.0 testbed - Barman. In this context, the AAS interpreter acts as a product agent. The paper begins with a detailed description of the concepts and terminology associated with this topic. This is followed by a detailed analysis of existing and new versions of the universal NFC reader hardware. The main part of the thesis focuses on the design of the AAS model, which is then implemented in the firmware of the microcontroller. This process also included the creation of an OPC Unified Architecture (OPC UA) server, which was used to thoroughly test the overall system. The results of the testing confirmed the successful implementation and functionality of the system. All theoretical scenarios were run according to the proposed AAS model, confirming the success of this approach. Thus, this work represents a significant contribution in the field of embedded system design in the context of Industry 4.0.
Switch board for FVE design
Kovář, Lukáš ; Holek, Radovan (referee) ; Kaczmarczyk, Václav (advisor)
This thesis focuses on electrical switchboard design and optimalization for a photovoltaic power plant. Within the design, the main requirements for the switch board, such as the output voltage of photovoltaic panels, the ability to monitor power, protection against external influences, and the output system, are defined. Thesis‘ key element is the implementation of modern technologies and control systems for power monitoring and control. The thesis explores the possibilities of using automation technologies for optimal energy utilization and maintenance costs reduction.
Manufacturing process optimization
Štěrba, Zdeněk ; Baštán, Ondřej (referee) ; Kaczmarczyk, Václav (advisor)
The thesis deals with the analysis of the production line in terms of overall efficiency. The aim is to define the areas that play a role in the overall efficiency and then devise appropriate solutions to improve them. Emphasis is placed on the analytical analysis method Basic MOST, according to which the normalized time of operators is determined. The next section focuses on analysis to identify weak points in the line that can be optimized to improve efficiency or achieve financial savings. The production line and its analysis is also treated as a discrete event system in Siemens Plant Simulation software, which is also used to design the new workstation. The last point of the work is the design of a digital twin concept in Siemens NX program, which is controlled by a simulated PLC.
Design of a system for optimal routing of people in closed spaces
Otevřel, Josef ; Husák, Michal (referee) ; Kaczmarczyk, Václav (advisor)
The aim of the bachelor thesis is to conduct a survey of existing systems for collecting and evaluating data on the movement of people in shopping centres and to evaluate them. Furthermore, to construct a device capable of counting the passage of people. To design and implement the software part of this system and to write the documentation. Finally, test the functionality and evaluate the obtained results.
Industry 4.0 Asset Administration Shell design
Tkadlec, Prokop ; Jirsa, Jan (referee) ; Kaczmarczyk, Václav (advisor)
The aim of this work is to create a simulation model that will correspond to the real TestBed Barman network, with the help of AAS data model devices. The simulation model will be created using the OMNeT++ simulator. The thesis describes the concepts of Industry 4.0, especially AAS and the individual cells of TesBed Barman. Afterwards the AAS models of production cells and intelligent products created by using the AASX Package Explorer program are described. The practical part describes the created TestBed simulation model and its individual modules that were created. Two simple simulation scenarios are then described for the simulation model together with the variables to be monitored.
Realtime system for web analytics
Hrubý, Otto ; Kaczmarczyk, Václav (referee) ; Holek, Radovan (advisor)
This thesis deals with the design of a realtime system for web analytics. The aim of this work was to implement this system. At first, research was conducted on existing tools and suitable technologies, based on which the system architecture was designed. Data from websites are collected by tagging the pages with JavaScript. The collected data are sent to the public cloud, where the system is deployed. The system processes the data, stores them in a database and makes it accessible to users through an information system.
MES for Industry 4.0 demonstrator
Martiník, Tomáš ; Arm, Jakub (referee) ; Kaczmarczyk, Václav (advisor)
This bachelor's thesis deals with manufacturing systems, their functionalities and their role in Industry 4.0. This thesis focuses on the design and implementation of the MES solution for the Industry 4.0 demonstrator. Research of available open-source systems is conducted and, based on the requirements for the system, one solution is selected, modified for the demonstrator's needs and integrated into its system.
PLC process control of more tanks based on standard S88
Dizorzi, Matúš ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
Main task of this work is to create a solution to PLC process control of more tanks based on ISA S88 standard. This work will be used as a study material to laboratory exercises during master’s study. First part of this work deals with the ISA S88 standard. The second part deals with analysis of created program from its most basic parts to complete functional tank. Conclusion of this work is to confirm functionality of this program by simulated demo version – visualisation in WinCC.
Hardware and software of a smart home appliance
Blaha, Vít ; Kaczmarczyk, Václav (referee) ; Fiedler, Petr (advisor)
Nowadays, the interest in smart appliances, which enable consumption reduction or consumption shifting approach, grows up. Such appliances can react to actual situation in the distributional network. From the energy distributor point of view, the activity of these appliances brings improvement of stability in the distribution network, while for the end customer there is possibility of the saving money. This thesis describes a transformation of standard fridge to smart fridge controlled by microcomputer Raspberry Pi. The smart fridge can communicate with supervisor system and according to its instructions change its behavior (temperature set point). The appliance can be manually controlled by a group of buttons, while its state can be visualized on the alphanumeric display. Last but not least way to control the appliance is through a web interface. The thesis also describes design of printed circuit board (PCB), which is designed for connection of all necessary sensors and actuators to Raspberry Pi. Software equipment is designed in the C++ program language.
