Determination of CAN operating limit conditions with respect to cabling and its topology
Mihulka, Martin ; Kufa, Jan (referee) ; Poměnková, Jitka (advisor)
The bachelor’s thesis deals with determining the operational limit conditions, designing, and theoretically describing CAN bus models for various types of cabling and verifying the limit condition through measurements. The aim was to establish the operational limit conditions for error-free data transmission. Furthermore, the objective was to design bus models, specify important parameters for different types of cabling, and verify the limit conditions thorough measurements. The thesis defines the limit conditions and proposes individual bus models according to the requirements, and for these designs, the important parameters for the error-free operation of the bus are measured.

CANopen drive PLC control
Hámor, Martin ; Knobloch, Jan (referee) ; Ctibor, Jiří (advisor)
The main goal of this bachelor’s thesis was to create an electric drive controlled by a PLC using the CANopen protocol. Three methods of message transmission were tested using Schneider Electric Machine Expert Logic Builder software, designed for PLC programming, and PCAN-View, which monitored incoming and outcoming messages in real time. Control methods are detailed in chapter 6, one of these methods was successful.

Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.

Control of emergency lighting by Foxtrot system
Hanák, Petr ; Klaban, Jaromír (referee) ; Bátora, Branislav (advisor)
This work is about control of emergency lighting, standards and requirements for their operation and installation. Requirements for operation and safety of emergency lighting by valid standards are mentioned same as requirements for construction, installation and checking. Control of emergency lighting is realized by Foxtrot system. There are listed its properties, each part of the system, possibilities of installation and connection of systems modules and parts. Mentioned are also other ways of systems control of emergency lighting and specific examples of systems used by developers of lighting systems.

Matrix headphone amplifier for studio monitoring
Štěrba, Václav ; Petržela, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor´s thesis describes the design of a matrix headphone amplifier for studio monitoring. The proposed amplifier is a purpose-built device to be used in studio sound recording for the mixing of multiple audio channels directed to the interpreters´or performers´ headsets. The device is basically composed of the following parts: An input section for the audio line, a mixing section which secures the setting of individual input levels for each output, an amplifier section allowing the setting of the output signal level for each output, and an output section enabling the connection of headphones. The equipment utilizes a connection to a multi-channel audio signal bus; this bus also provides for remote power supply to all the connected devices. The solution described in the thesis can be defined as alternative monitoring that facilitates quick and easy connection of a required number of monitoring points (in other cases, such monitoring is usually realized by means of individual small mixing consoles).

Module of Digital Outputs with Modbus Communication
Vaško, Pavel ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Goal of mine bachelor’s thesis is create functional module of digital outputs, which can be seen in typical industry using. This module must contain communication interface on protocol Modbus and standard communication bus RS-232, RS-485. The module must be equipped with microcontroller series x51. Size of equipment must be minimalized into the smallest proportion. One part of the thesis is focused on theoretic information about Modbus protocol. Next parts contain charakteristics of communication and software facility.

Controlled lighting and shading in smart house
Novák, Michael ; Morávek, Jan (referee) ; Bátora, Branislav (advisor)
This bachelor‘s thesis is focused on controlling lighting and shading in a smart house. Lighting control covers switching and dimming mechanisms. This thesis presents dimming options for different types of light sources. Following this is an overview of shading devices and system wiring, often called smart wiring. Specifically, the thesis focuses on the Foxtrot system from Teco a.s.. This work describes the sensors and actuators used for switching, dimming and shading control devices. New library of functional blocks for lighting and shading control for Foxtrot system was created, for they were not included in any standard library. All functional blocks that have use in the control of lighting or shading - including standard ones - are described in this work.
