Wireless Communication in Fire Sport
Pelka, Tomáš ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
This work describes the design of wireless timer for fire sport disciplines. Its aim is to replace long wires with wireless communication while preserving equal or better reliability. Important part is the need for clock synchronization between wireless modules. Related topic is selection of suitable synchronization algorithm and communication protocol. The proposed system was realized in form of prototype using Texas Instruments's development platform LaunchPad EXP 430 FR4133 and wireless modules with Texas Instruments's chip CC1101. Parameters of designed system (especially the accuracy of time synchronization and measurement) were verified in laboratory.

Modern wireless technologies - ZigBee
Krajíček, Tomáš ; Koutný, Martin (referee) ; Skořepa, Michal (advisor)
This bachelor work tells about wireless security of house – ZigBee. It is introducing problems of wireless technology based on standard IEEE 802.15.4, comparing to another wireless technologies and presenting potentionalities of it’s use and areas of it’s excercise. The work is related to creation of simulated model in OPNET Modeler environment, which simulates a field of sensors. The purpose of the whole effort is to state time-delay of information transfer, specify reliability of the transfer and lay down energy intensity of the process runned over the area of sensors.

Lightening control system with wireless interface
Hrbáček, Jan ; Srb, Jan (referee) ; Bradáč, Zdeněk (advisor)
The goal of the bachelor's thesis is to design a lightening control system with wireless interface intended to be used under conditions not allowing permanent control wiring. The system consists of one coordinator and several end devices communicating in accordance with the IEEE 802.15.4 Standard. The thesis includes background research on the theme and possible solutions, description of the circuit and the mechanical construction and analysis of the devices application firmware. The resulting devices built according to the thesis were continuously improved, so that the design is now fully functional and reliable.

Electronic timekeeping with movement detection
Paulus, Luboš ; Brož, Vladimír (referee) ; Klusáček, Stanislav (advisor)
Agility is a competition for dogs and their whipper. The score is made from numbers of errors which dog made and also time in which the dog overcomes crimps decides. Start and finish are detected by the reflective optical spar with logical NPN output. Spar havs to detect only dog in set position in recruit. This signal is processed by a micro – controller, which processes data, more precisely time with accuracy on tenths, sends data on the superior PC.The communication of micro-controller and PC is possible only through USB, RS 232 or wireless RS 232.

Project Pretrigger
Veverka, David ; Pavlík, Michal (referee) ; Háze, Jiří (advisor)
Práce se zabývá návrhem stabilního a rychlého bezdrátového spojení mezi dvěma body. K vytvoření tohoto spojení bude použita technologie Bluetooth a nebo její moderní alternativy vzhledem k tomu, že tato technologie již byla v daném pracovním prostředí testována a byla prokázána její stabilita. V této práci a v navazující diplomové práci budou diskutovány výsledky časových analýz zvolených senzorů, komunikace mezi senzorem a zvoleným mikrokontrolerem a nakonec návrh kompletního řešení, na jehož základě bude vytvořen funkční prototyp požadovaného zařízení.

Advanced Weather Station with Image Transmission
Augustin, Stanislav ; Fedra, Zbyněk (referee) ; Povalač, Aleš (advisor)
The content of this diploma thesis is a hardware and software design of advanced weather station with image transmission. The meteostation consist of two units - outdoor and indoor unit. Outdoor unit provide processing measured values from temperature sensor, atmospheric pressure sensors, rain gauge and windmeter. It also provides processing of captured image and wireless transmission of measured values to indoor unit. Indoor unit should provide comfortable meteostation controlling and visualization of weather situation by web interface.

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.
