IEC 60870 communication simulation
Calábek, Tomáš ; Kohout, David (referee) ; Bohačík, Antonín (advisor)
This bachelor thesis focuses on the development and implementation of a simulator for the IEC 60870 communication standard, specifically for IEC 60870-5-101 and 104 protocols. The aim is to create a unified control interface capable of simulating both the client and server side of these protocols, which are essential in the energy sector for reliable and efficient communication between devices. The theoretical part of the thesis provides a detailed study of IEC 60870 protocols, SCADA system and equipment operation in the power sector. It also considers the comparison of IEC 60870 with other standards used in the power sector. The practical part includes the design and implementation of a simulator that allows for complex control, including the configuration of the output data flow (e.g. data/query periodicity or range of values generated). The final part of the work deals with testing and comparison of the simulator with another solution.

Controlling LEGO Powered-up Hub from EV3
Potoček, Jakub ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
This work deals with the communication between two incompatible programmable LEGO bricks, the LEGO Mindstorms EV3 and the LEGO Control+ Technic Hub. The task of this work was to create a communication interface enabling the transfer of data between these two bricks and thus enable the EV3 brick to send and possibly also receive data from the Technic hub brick. During the creation of this work, I designed and constructed two prototypes using an optical interface for data transmission. The second prototype enables two-way communication. This enables data from sensors and function return values to be transferred to EV3. Despite the fact that the resulting solution does not allow fast enough data transfer due to the technical limitations of the Technic hub brick, this solution is suitable for use by owners of these LEGO building blocks looking for ways to use both bricks when creating models.

Sample divider optimized for a specified group of bulk goods
Rolný, Jakub ; Nevoral, Tomáš (referee) ; Škrabánek, Pavel (advisor)
Tato práce se zabývá vývojem nastavitelného děliče vzorků pro semena různých velikostí a tvarů. Jeho účelem je vytvářet reprezentativní vzorky frakcí, nastavených obsluhou, ze vstupního materiálu, který má být vzorkován. Hlavním cílem bylo vyvinout a otestovat tento typ děliče vzorků. Dělič vzorků byl vyvinut na bázi minipásového dopravníku s klapkou umístěnou na konci dopravníku, odkud se materiál dělí do boxů na vzorky a na zbývající materiál. Pro dělič vzorků byly vyvinuty a testovány čtyři různé typy dopravníkových podavačů. Výsledky testu ukázaly, že verze C dopravníkového podavače poskytuje nejlepší výsledky. Závěrem lze říci, že nastavitelný dělič vzorků usnadňuje produkci reprezentativních vzorků různých semen na jediném zařízení, na rozdíl od použití více komerčně dostupných děličů vzorků, které jsou určeny pro specifické velikosti a tvary částic materiálu.

Power Line Communication for Home Automation Applications
Hromádka, Michal ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
This thesis describes the design of a modem for a communication over residential power lines. First part is focused on the history, suitable frequency bands, modulation techniques and mainly on the selection of the optimal modem device. Second section contains the description of the hardware design of the modem itself and clarifies the implementation of the PLC module to be used as a communication interface for a full residential automation solution. Last chapters of this thesis introduce the communication protocol, design of the software for the ATmega32 MCU and present of the final field testing under real conditions.

Tools for Environment for the Simulation of Communication
Mikuš, Peter ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
Communication between devices should be based on predefined rules. These rules are called communication protocols. In this master thesis I am concerned with communication protocols, specially security protocols. Their design demand specialized tools, that will provide interactive simulations and security testing. I have described each of these tools in detail and mentioned about their properties, their pros and cons. In available tools I have implemented security protocols. The result is set of demonstration tasks that are usable in network courses at FIT VUT

Communication protocol implementation into signal processors
Červenec, Radek ; Daněček, Vít (referee) ; Herman, Ivo (advisor)
Práce se zabývá studují, modifikací a návrhem komunikačních protokolů a jejich implementací v digitálních signálových procesorech v jazyku instrukčních adres. Také zkoumá strukturu elektro-akustické jednotky EPIS 2.45. Popis jednotky je zaměřen na její softwarovou část a to zejména na operační systém založený na kooperativním multitaskingu. Pro dosažení úspěšného návrhu a implementace komunikačních protokolů se práce zaměřuje také na základy vícevrstvé síťové architektury. Poté je již zkoumána skutečná síť (Koris Net) společně s jejími, ale i dalšími komunikačními protokoly, jako například protokol Modus. Popis je doplněn o příklady zdrojového kódu jejich implementace v digitálním signálovém procesoru (ADSP 2191M). V práci je mimo jiné prezentován navržený komunikační protokol pro vyčtení souboru z palubního počítače připojeného k jednotce na sběrnici Modus. Společně s tím je také obsažena navržená úprava protokolu, tak aby bylo možné předávat stažené soubory přes radiové rozhraní do centrálního počítače.

Autonomous mobile robot
Pijáček, Ondřej ; Kopečný, Lukáš (referee) ; Jílek, Tomáš (advisor)
This thesis describes the design and implementation of chassis for autonomous wheeled mobile robot along with a proposal for a suitable control system. To move the robot was necessary to create individual modules for measuring environmental data, its subsequent processing and power management. For the entire robot system capable of rapid interaction, certain tasks are separated and controlled by its own microcontroller. For communication between the modules were chosen and designed SPI bus communication protocol. Thus assembled chassis then communicates over a serial line with higher system from which acquires data indicative of a subsequent procedure. The result is a controlling system communicating between its parts. Part of the design is also defined communications protocol that transmits data on the one hand and also used for fault diagnosis when sending information. Furthermore, there are patterns and specific methods for controlling the individual modules. In conclusion, the thesis described the proposed testing the robot in real conditions, along with the measurement results obtained in the task of autonomous driving.

DMX console for stage lighting control
Schilhab, Jan ; Chladil, Ladislav (referee) ; Čech, Ondřej (advisor)
The bachelor thesis deals with the question of controlling stage lighting using the DMX 512 protocol. The thesis describes the function of this protocol in details and compares several types of commercially available lighting consoles. The comparison shows some functions and features of the consoles, which are used to design the concept of the actual console. The main part of the thesis is the design of the circuit blocks of the lighting console and a description of the implementation of a functional prototype. The development of the entire control software is also an integral part. The work is concluded with an evaluation of the achieved features and functions of the implemented device.
