Automation of climatic data acquisition
Sádovský, Petr ; Pikula, Stanislav (referee) ; Uher, Miroslav (advisor)
The goal of this work is to understand and identify the communication of the COMET S3120E datalogger. Subsequent design of a circuit solution that will allow two-way communication with the datalogger and the compilation of control software for the PC. The basis of the work is a theoretical and practical part. In the theoretical part of this document is a theoretical description of the functionality of the datalogger and its components. It also contains a description of the software used to achieve the goals. The las part deals with circuit design and software for PC.

Serial Data concentrator in VHDL
Řeháček, Tomáš ; Valach, Soběslav (referee) ; Burian, František (advisor)
In the bachelor’s thesis text there are summarized basics of VHDL language, ISE Webpack development environment is described. Also the way of communication and properties of serial unit are described as well as Ethernet standard properties and the way of communication via MII interface. Hardware used for the data concentrator design is briefly introduced in the next part. At the end of the thesis there is analysis of the data concentrator design for data transmission from serial unit to Ethernet using protocols UDP/IP.

Logic analyzer for teaching
Dobrocký, Marcel ; Macháň, Ladislav (referee) ; Levek, Vladimír (advisor)
This bachelor’s thesis deals with a design of USB logic analyzer that will be used for teaching purposes in laboratory environment. The main purpose of the logic analyzer will be analysis of serial communication protocols most frequently used in embedded systems - UART, SPI and I2C. The analyzer can be also used as a debugging tool while designing all sorts of digital systems. In the first part of this thesis, the theoretical background of above mentioned communication protocols is explained. The next chapter deals with the process of signal analysis with the designed analyzer. It also contains a detailed description of the hardware module design. The last part deals with designing the microcontroller firmware and PC software, while explaining different applications of the analyzer in teaching.

Meteo Probe for the Measurement of Basic Atmospheric Quantities
Pumr, Martin ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
The bachelor thesis focuses on the problematics on basic atmosphere sounding. Its content is a study of the physical properties of the atmosphere. Based on these findings, the design and implementation of a specimen meteorological probe and ground receiving station are carried out. The meteorological probe records atmospheric data at regular intervals and stores them in CSV format. The probe continuously reports information about its position, and after completion of the measurement sends all measured data to the ground receiving station, where data evaluation and further processing takes place.

Development of monitoring application for a production cell workspace with SICK scanners
Dostál, Tomáš ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
This thesis is about scanners of SICK company and monitoring methods in workspaces. Next in this thesis is described implementation of monitoring methods in robotic industry. Objective of practical part was design, implementation and to test application created in LabVIEW for monitoring workspaces. Created application contains choice of use serial communication with scanner SICK PLS 101-312 or possibility to create simulation of monitoring workspace. In conclusion both choices are tested and evaluated.

Data logger for serial communication lines
Jankech, Tomáš ; Šebesta, Jiří (referee) ; Dušek, Martin (advisor)
The aim of bachelor’s thesis is the realization of data logger for serial communication lines. This paper describes basic concepts of serial communication and looks more deeply into RS232 and RS485 serial communications standards. It describes usual methods of data recording and their application in practice. Data logger’s block diagram is described in detail for each of its parts. Their descriptions contain an overview of circuits, which allows realization of individual blocks and circuit diagram of selected circuit. Following chapters describes design of printed circuit board, control application for PC and firmware for the microcontroller.

Position sensing detector
Ha, Tuan ; Wilfert, Otakar (referee) ; Barcík, Peter (advisor)
This thesis deals with design of a laser position detector. Different types of sensor are mentioned and compared at the beginning. Special attention is paid to quadrant sensor. Its pros and cons are discussed with designing methods. The sensor is simulated in Matlab to test its output response. Then the laboratory tests follow to meassure real response of the chip. Then follows the design of the detector based on measured and simulated data. In the conclusion of this thesis parameters of created device are evaluated.
