Design of a Topology of a Distributed Control System for Home Automation Using IoT Technologies
Mokrejš, Jakub ; Baumgartnerová, Alena (referee) ; Ellederová, Eva (advisor)
Bakalářská práce vymezuje koncepci internetu věcí, chytré domácnosti a distribuovaného řídícího systému, poskytuje přehled komunikačních protokolů a služeb chytré domácnosti a následně diskutuje autorův vlastní návrh topologie chytré domácnosti. Práce nejdříve popisuje internet věcí a oblasti, ve kterých se využívá. Poté se práce zaměřuje na chytrou domácnost, a to konktrétně na sítě a topologie, které v ní mohou být použity. Dále je provedena analýza a srovnání sítí a topologií s ohledem na jejich použití, výhody a nevýhody. Následuje popis distribuovaného kontrolního systému a na to navazující přehled komunikačních protokolů. Popis služeb a prvků chytré domácnosti uzavírá teoretickou část práce. Praktická část práce se zaměřuje na návrh vlastní topologie a prvků pro chytrou domácnost. Práce je zakončena porovnáním vytvořené topologie s ostatními topologiemi.

Drivers in PLC TC700/Foxtrot for feeder protection REF630/REF615
Till, Přemysl ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
This thesis deals with communication within industrial systems, specifically using standard IEC 61850. The theoretical part contains a list of useful resources detailing IEC 61850 and a brief summary of the data model and model of vertical communication defined by the standard. In the practical part, a library for vertical communication between a Tecomat Foxtrot or TC700 PLC and an IEC 61850 conforming device was designed and created. It provides function blocks for establishing a communication channel, reading and writing data using the standard. Its functionality was tested using a feeder protection and control REF630 from ABB.

Using of voice for home eguipment control
Bubla, Lukáš ; Vojáček, Zdeněk (referee) ; Lacko, Branislav (advisor)
The bachelor thesis is focused on home automation, specifically on voice control. It describes methods of communication and control of automated systems and especially problematics of computer voice recognition using different methods. The thesis displays specific product for voice controlling developed by Czech company Elko ep, s.r.o. and then briefly looks at the issue of gesture control. At the end compares product from Elko ep with other products from foreign companies and discuss advantages and disadvantages of voice or gestures control.

Internet of Things (IoT) Security Risks and Threat
Urbanovský, Jozef ; Grégr, Matěj (referee) ; Ryšavý, Ondřej (advisor)
The bachelor's thesis deals with the issue of security and attacks on the Internet of Things devices. The document addresses nature of Internet of Things, its characteristics and information security. The thesis analyzes dierent protocols and standards used by Internet of Things and types of network attacks. Part of work consists of packet capture analysis from IoT honeypot and showcases discoverd attacks. In fnal part, one specifc IoT device is analyzed in terms of security, around which is created an experimental IoT system. Subsequently this system is penetration tested with dierent attacks, thus creating new datasets.

User Interface for Technology Control
Zapletal, Filip ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
This paper describes systems and user interfaces for monitoring and supervisory control of technological equipment. It describes basic approaches used to solve this problem, commonly used communication protocols and existing user interfaces. Based on those findings are defined requirements for design of a modern user interface for technology supervision and control, particularly in the area of clean and waste water distribution systems. The thesis concludes with a description of a user interface based on defined requirements and finally compares them with existing systems.

Application for the HAWK regulator
Kvasnička, Petr ; Štohl, Radek (referee) ; Jirgl, Miroslav (advisor)
This bachelor’s thesis deals with the issue of intelligent buildings management and practical use of the control system HAWK from company Honeywell. The thesis describes the basic problem of intelligent building management, exactly why they created and how it is possible to implement building automation, including a listing of available equipment that can be used in these systems. The thesis also discusses one of the systems that can be used for building control. The control system is called HAWK and thesis describes the programming environment and connectable peripherals. For a given control system is formed in the scrubbing practical demonstration device wind tunnel, which is shown using the work of the control system.

Home security system - remote access module
Šarda, Petr ; Bradáč, Zdeněk (referee) ; Fiedler, Petr (advisor)
This thesis deals with remote access module for electric security systems (ESS). The design is based on valid standards that apply to a production of electric security system. It includes a design of module connection to the central that controls the module. There is also a communication protocol for connection with the central and with the user. The last step is development of web interface, which is realized on the selected development kit.

Communication protocol for built-in facilities
Dolák, Petr ; Burda, Karel (referee) ; Herman, Ivo (advisor)
Questions connected with communication technologies are really serious problem worldwide and this Bachelor’s thesis deals with this topic. Concretely is aim of this thesis Communication protocols. They are one of the basic keys in any data transfer, becausse they creates the basic environment for communication between users. First part of this thesis specifies nowadays used communication technologies, however range of Bachelor’s thesis do not give enough space for discussion all used technologies. The main aim of this part is to discuss used technologies on first three levels OSI model. It has been given to made a three layer solution and it has two possible results. In the second and third part has been this two results discussed, by realizing two differnet communication protocols. The first one deals with three lower levels of OSI model, and it is connected to non-error transfer and working with data. It means uploading and downloading them. Protocol build on higer levels of OSI model delas with good communication, however is more specified for services used by in-built units. The last part of this thesis includes diagrams and simulations performed in SDL language.
