Integration of Simulator in AAS for Heat Transfer Station
Černocký, Petr ; Jirsa, Jan (referee) ; Arm, Jakub (advisor)
This work examines today's modern methods of production management, without which the entire Industry 4.0 phenomenon would not be possible. The main focus of this work is the Asset Administration Shell and the integration of models and simulations into it. Furthermore, research is carried out in the area of modeling and visualization of production and production processes, which is also provided with an example of communication between the visualization software UNITY and the calculation software Matlab. From the analysis, the most suitable software is also selected for the final implementation. Furthermore, there is a proposal for the integration of the simulator into AAS and then its practical implementation. At the same time, the entire designed system with an integrated simulator is evaluated here.

Standard faceplate for WinCC Unified
Nepivoda, Tomáš ; Arm, Jakub (referee) ; Benešl, Tomáš (advisor)
The topic of this thesis originated from the requirements of Mechatronic Design & Solutions. Its primary goal is the transition to the visualization software SIMATIC WinCC Unified, focusing on the time efficiency of creating visualization applications. This work addresses the issue of automatic screen generation based on control software developed for Siemens PLC machines. The process of automatic screen generation itself involves several intermediate stages and complex steps. The thesis focuses on creating a theoretical foundation in the field of operator panels, the relevant standards for their creation, and descriptions of the software utilized. The practical part is dedicated to the development of company standards and the implementation of complex and universal functional blocks, for which separate service screens are created. The final section is devoted to the actual implementation of automatic generation in connection with the developed PLC program and the created HMI Screens.

Implementation of Communication Technology complying IEC 61850 as the Demonstrational DCS System
Kozák, Ondřej ; Arm, Jakub (referee) ; Fiedler, Petr (advisor)
This thesis deals with the issue of communication of protection by IEC 61850 standard and reading, control and visualization of protections by DCS systém 800xA and PLC AC500 from ABB and extended visualization by cloud service Grafana. The IEC 61850 standard, its protocols anad the topologies used have been descibed in this work. Furthermore, the basic functions of the instruments used were described. The main part describes the procedure of creating SCD file for communication configuration and subsequent uploading to individual systems, creating visualization in DCS 800xA system, setting up communication between protection devices and reading from them using AC 500 PLC. For the cloud service there is a description of the implementation of the MQTT broker for sending data between PLC and database Influxdb that stores the data and forwards it to Grafana visualization environment.

3D Printer Remake
Čtvrtníček, Jan ; Husák, Michal (referee) ; Arm, Jakub (advisor)
Purpose of this thesis is revitalize an existing 3D printer. It briefly summarizes the possible technologies of 3D printers with a focus on FDM technology and elaborates in more depth the possibilities of X and Y axis movement. Above all, this thesis is dedicated to the design of a 3D printer model according to selected technologies so that it meets the required parameters. Subsequent implementation is based on the precise selection of mechanical and electrical components. It also deals with the implementation of the Klipper utility software on the OctoPrint interface. The entire printer is designed as an enclosable cell with automatic print unloading.

Triggering device for CANbus
Piroch, Vojtěch ; Arm, Jakub (referee) ; Burian, František (advisor)
This bachelor thesis deals with the design of a triggering device for the CAN bus that allows connection to the trigger input of an oscilloscope and display of the signal waveforms of the CAN bus frames. The first part of the thesis deals with the theoretical description of the CAN bus itself, its principle of operation, description of frames, etc. The second part of the thesis deals with the selection of the core components needed for the circuit, the design of the final schematic, the definition and calculation of the individual components in the circuit and the method of control. The third part is practical, it is dealing with testing the prototype device, designing the circuit board and packaging for the device. The following section describes the software part of the device, specifically how to control the device, a description of the program and libraries used in programming the microcontroller. The last section describes the final testing and measurement of parameters such as jitter and trigger pulse delay.

Automated testbed for SIL/PIL testing of embedded application using FPGA
Prusák, Lukáš ; Burian, František (referee) ; Arm, Jakub (advisor)
The master's thesis deals with designing a testbench for a selected soft-core processor NEORV32 with a RISC-V architecture for simulations of embedded applications in an FPGA environment. The testbench was created in the Vivado environment with the aim of extending it to a testing and validation framework. Basic modules such as GPIO, PWM, UART, and PC were selected and implemented. Several test scenarios have been designed for these modules. The testbench has also been supplemented with additional scripts, to create hierarchically correct project setup and test execution. The work also suggests a few possible ways to improve and expand the testbench.

Indoor flexible wireless CO2 measure system
Válek, Vít ; Fiedler, Petr (referee) ; Arm, Jakub (advisor)
Monitoring of the carbon dioxide concentration in the building is carried out for several reasons. One is to ensure hygiene conditions. With the advent of Bluetooth 5.0 came the support of mesh network technology, which is defined by the Bluetooth Mesh standard. By implementing this standard, we can create an extensive network of devices monitoring the concentration of carbon dioxide in the building. Based on the monitored concentration, we can control the air conditioning and ventilation of the spaces, ensuring that the hygiene conditions are met. Thanks to the compatibility of Bluetooth Mesh with Bluetooth Low Energy, it is possible to access individual nodes, e.g. from a mobile phone. The aim of this work is to design and implement a measuring system whose elements will communicate with each other using Bluetooth Mesh wireless technology.
