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.

CFD analysis of the airflow for the different types of flowmeters
Drexler, Pavel ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
There are some basic information about pressure sensors and flow in the first part of my diploma thesis. For example turbulent and laminar flow, construction of pressure sensors and basic information abaut Ansys and –Fluent. Main part of this thesis is focused on CFD simulation of pressure and velocity in the vicinity of pressure sensors. I confront this simulated values with measured values in final part of this thesis.

Design of the user-friendly touch screen GUI and a physical connection to an existing simulation hardware device
Husar, Jan ; Kaczmarczyk, Václav (referee) ; Štohl, Radek (advisor)
Práce uvádí základní informace o průmyslové sběrnici AS-Interface a popisuje její funkce. Dále se zabývá rozšířením stávajícího FTZ AS-Interface Slave Simulátoru o dotykový display, který značně usnadní ovládání tohoto simulačního nástroje. Je zde nastíněn návrh a řešení uživatelského dotykového rozhraní k tomuto simulátoru s použitím Amulet LCD modulu STK 480272C. Vývoj tohoto rozhraní je proveden pomocí GEMstudia, softwaru firmy Amulet Technologies a grafických programů. Dále tato studie pojednává o softwarové úpravě FTZ AS-i Slave Smilulátoru. Jedná se o úpravu řídícího FPGA v jazyce VHDL zajišťující komunikaci s dotykovým displejem. Poslední kapitola se týká problematiky spojené s návrhem uživatelsky přívětivé aplikace.

Control of lift model with the fieldbus AS-Interface
Goryl, Stanislav ; Knobloch, Tomáš (referee) ; Štohl, Radek (advisor)
The aim of the master thesis is to create and verify the control algorithm of a personal lift. First part of the thesis focuses on a literature review investigating the requirements for personal lifts. Based on the information found in the review, selected measures were implemented in the model so that it would be the most suitable to the requirements for personal lifts. A brief introduction of the lift and its norms is followed by a description of the programme and control algorithm, including the description of the used add-on instructions. Last part describes the visualization which is used to control the lift model. In addition to controlling, the visualization provides statistical data, the current status of the programme and information about the set parameters, inputs, outputs and faults.

Design of module for demonstration and testing of system basis chips NCV7471
Kresta, Martin ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
Práce se zabývá návrhem automobilové elektronické řídicí jednotky (ECU) s funkcí partial networking definovanou normou ISO 11898-6. Cílem je navrhnout a vytvořit demonstrační ECU s použitím system basis chip NCV7471. Protože NCV7471 obsahuje standardní CAN transceiver, funkce partial networking je realizována pouze softwarem řídicí jednotky. Práce zvažuje možné způsoby realizace jak HW, tak SW části, tak aby byla zajištěna nízká spotřeba ECU v různých operačních módech, a snaží se sledovat současné trendy v automobilovém průmyslu.

Foundation Fieldbus peripheries
Ferjančič, Michal ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
Master’s thesis deals be occupied with the transmission of process data with peripheries to control devices. Data transmission with performs through two types of industrial networks. Use with these two Foundation Fieldbus and EtherNet / IP. In work is shows method conversion through gateway between the two networks. Here there is adduced method to connected and configure devices on the networks and also their implementation. Part of this work is also creating a visualization of these peripherals and the gateway. The work is also presents possible use for laboratory task to practice.

Add-on instructions for AS-Interface Network
Grepl, Tomáš ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
This master's thesis deal with design and creating of the instructions for industry bus AS-Interface. These instructions were implemented in the software ControlLogix5000 like add-on instructions. In the teoretical part there are presented the issues of industrial control, AS-Interface bus, add-on instruction and model of the labyrinth. The practical part of the master's thesis is focused to design of the add-on instruction and work with instruction and its characteristics followed by the description of the sample add-on instruction and the list of all implemented instructions. The final two chapters include visualization and laboratory exercise.

Safety of manipulator model
Peňáz, Ondřej ; Stibor, Karel (referee) ; Štohl, Radek (advisor)
The work deals with the functional safety of machinery, in our case with the model of the 3D manipulator. The main contribution of this work is the detailed conduct a risk assessment in accordance with the valid legislation and the detailed design of safety components to meet the safety requirements. Protective measures are carried out by three steps. The work includes a description of the implemented measures, mainly change of the design and creation a SafetyTask for the PLC. Also the visualization for a touch panel was created. At the end of the work we had to verify and evaluate implemented safety measures.

Microbending fiber optic sensors
Švestka, Jiří ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
This thesis deals with the influence microbending the transmitted signal at the bare optical fiber. Microbending influence on the transmitted signal is investigated in this work by changing the weight, power and water level in the tank by using this test fixture. The results of the experiments are proposed to enter the laboratory tasks to measure the impact microbending the transmitted signal in the subject line fiber-optic sensors (MOES).
