Control of glasshouse
Czudek, Aleš ; Kaczmarczyk, Václav (referee) ; Štohl, Radek (advisor)
This report deals with a solution of the student project called Greenhouse controlling. The aim was to equip a real glasshouse with application technology using electronic control system Siemens and bus technology AS-Interface. You can find here a description of the function of the glasshouse, used hardware, technological scheme and identification of controlled system.

Processing of the RC plane model telemetry
Žák, Tomáš ; Fedra, Zbyněk (referee) ; Prokopec, Jan (advisor)
Bachelor’s project focuses on problematic about scanning state of RC plane model, during the fly. In detail there is described internal and external structure, including communication. Main objective of work is design functional board for scanning state of RC plane model, during the fly. There is used akcelerometer for scanning actual state of plane. Accelerometer sends measured data in digital form to microcontroller for evaluating. List of used components is in the enclosure.

Serial communication
Novotný, Bohumil ; Šilhavý, Pavel (referee) ; Martinásek, Zdeněk (advisor)
Bachelor work is focused on the issue of a serial communication interface RS-232,USB, I2C and SPI, and also discusses the use of the laboratory module for experimental purposes. Laboratory module is designed with respect to the functional elements that will resist daily use of students. This work is detailed principles of serial communication in relation to each interface. The second part is devoted to method the module structure, functions of its individual components and functional solution output connectable to an oscilloscope and other measuring devices.

Modernization of the master clock for slave clocks controlling
Pokorný, Jiří ; Číž, Radim (referee) ; Krajsa, Ondřej (advisor)
This diploma thesis describes modernization of the master clock HN 50 created by company ELEKON, s.r.o. Master clock can be used for controlling of analog or digital slave clock or for switching school bells. Exact differences between old and new version of the clock are described and ways of synchronization and controlling of slave clock are explained. Main goal of modernization is applying the SMT technology for automation of production. Another problems and shortcomings of previous version are developed, such as new power supply structure, selection of a new microcontroller and usage of several different displays. Every problem is developed and new solutions are chosen. Last part of the document describes the software which is clarified on several flowcharts. Outputs of the thesis are complete schematics, printed circuit boards and 3D models of the modernized device.

Multimaster communication over long distances
Hedvíček, Michal ; Málek, Petr (referee) ; Uher, Miroslav (advisor)
This bachelor project deals with a theoretical analysis of employed serial buses and a comparison of their qualities especially with regards to a medium-range distance. Also, it considers the possibility to extend I2C-bus by special circuits, which guarantee communication for longer distance. Next deals with measuring draft program for the collection and evaluation of measurement data. Following measurement itself and evaluation parameters of signal on the bus under different conditions.
