Model of small air press
Uherek, Vítězslav ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis deals with design construction of laboratory model of air press and also proposes of safety measures for this machine. Before the design itself, norms concerning machinery construction were surveyed. There are two norms mentioned in the text ČSN EN 61 508 and ČSN EN ISO 13489-1. Next part shows practical demonstration of machine safety analysis using SISTEMA software tool. Changes to the safety measures were made according to the result of this analysis. Important part of this thesis is also design of control software for the air press in RSlogix5000 environment using Ladder logic and also created visualization of pressing process and show up on to visualization panel PanelView 700.

Terminal for testing of data communication of public transport vehicles
Fiala, Michal ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
This term paper deals with subject of wireless communication of city rail transport cars. In this paper are described individual modules for transmission and receiving of data containing communication between city rail transport cars and measures of siding switches. Then there are discussed possibilities of design of system for testing functionality of transmitting and receiving modules and the system is consequently designed. There are also described communication principles and protocol used for wireless communication and MODBUS protocol used for communication over RS-485 serial line. In the end was the system manufactured, completed and equipped with necessary software.

System for communication between model car and PC
Petrov, David ; Beran, Jan (referee) ; Macho, Tomáš (advisor)
Bachelor thesis addresses communication between PC and carriage. It includes analysis of possible ways to transfer commands from PC to mobile robot. The resulting solutions are selected hybrid wireless modules Aurel RX BC-NBK-433 and TX-SAW433 / s working in the band 433 - 868 MHz. For the processing of transmitted data is used microcontroller PIC16F627A.

Control of 3-axis PCB drill
Kresta, Martin ; Dvořáček, Martin (referee) ; Macho, Tomáš (advisor)
This thesis is focused on design and realization of 3-axis PCB drilling machine. Design comes from mechanical construction of inkjet printer and reusing most of original actuators. This thesis is mainly focused on design of control electronic circuits and software equipment. The whole machine is controlled by 8bit AVR microcontroller ATmega64. Machine is also equipped with USB interface for communication with PC application. This feature allows automatic processing of CAM files from PCB design systems.

Implementation of PSD controller into microcontroler MCF52233
Lang, Stanislav ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
The goal of my bachelor thesis is the project and realization of a digital regulator, including the possibility of user’s settings. The first two chapters, which present a theory and a survey of the problem of digital regulation, offer an introduction as far as the used hardware (32-bit microcontroller M52233 from the company Freescale) is concerned. The main part of my thesis deals with the description of concrete implementation of regulation algorithms into the selected hardware as well as the communication with the regulation unit and the selection and basic configuration of the peripheral used.
