Wide area tracking system based on LoRa devices
Holík, David ; Arm, Jakub
The work deals with wireless communication using LoRa (Long Range) technology categorized as LPWAN (Low Power Wide Area Network). The technoloy enables wireless data transmission over long distances more than 5 kilometers in urban or rural areas. The technology is used as the communication between ESP32-based devices providing their GPS data and time synchronization. The system also consists Raspberry Pi which provides the central LoRa station for near area. The communication between central and peripheral devices was established using open-source libraries. The central device might need to receive packets from surrounding devices concurrently, whichi is not possible using the designed device, thus a protocol needs to be established as discussed. Moreover, the communication with the public TTN network has been tested. Regarding the communication testing, test scenarios were designed.

Integration of Simulator into AAS for Heat Transfer Station
Černocký, Petr ; Arm, Jakub
This work examines the Asset Administration Shell (AAS) in the role of modern management of production units, which is one of the key enablers of the Industry 4.0 phenomenon. The main idea is to connect the simulator with AAS and create a functional architecture that will correspond with the real system. The next step would then be to connect this system with the real one and manage it using this architecture. The open-source program OpenModelica was chosen for the simulation because of its versatile command line use. As an example, a heat transfer system is modeled and simulated. As the results indicate, the OpenModelica simulator takes time to run a simulation that depends on hyperparameters such as samples per interval. Also, submodel for simulation adapter could be templated.

Test benches for microcontroller kits
Žaludek, Ivo ; Arm, Jakub ; Bradáč, Zdeněk
This paper deals with the design of a test bench for modules used in educational labs. The first section outlines the requirements for the tester, followed by a description of the printed circuit board design process. Implementation details of the software are then examined, including a graphical user interface based on Model-View-Controller (MVC) architecture that allows for easy result printing. The obtained results are presented, and further work is discussed.

Modernization of laboratory equipment and creation of a laboratory task
Medek, Dominik ; Arm, Jakub (referee) ; Baštán, Ondřej (advisor)
This thesis deals with the creation of a teaching equipment, that will allow students to experience working with a PLC and its peripherals, as well as connecting the laboratory tasks and the PPA course project. The thesis discusses the PPA course, its laboratory exercises and the project. It lays out the requirements for a new teaching equipment, that is then created. Its potential uses are then evaluated and two laboratory exercises are created for which a possible solution is developed. The work also includes the establishment of a laboratory standard that addresses the uniform connector wiring for all laboratory teaching equipment and PLC panels.

Upgrading the Subsystem for Testing of the Safety Function of a Valve
Němec, Petr ; Fiedler, Petr (referee) ; Arm, Jakub (advisor)
The aim of this work is to develop a theoretical basis for the modernization of the subsystem for testing the valve function, the subsequent design and implementation of the visualization. The thesis briefly describes the steam turbine circulation and bypass technology. Thus, the technology of the system in which the safety function itself is located. Furthermore, the thesis deals with the functional safety analysis and describes the development of three analysis methods FTA, HAZOP and FMEA. The thesis also deals with the analysis and description of an existing application using a state diagram. From the subsequent analysis, the design of a new visualization is realized. The visualization is tested in the thesis using simulation which is performed on a real PLC and also using PLCSIM software.
