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.

Construction of On-board Computer for Motorcycle
Rulc, Martin ; Široký, Daniel (referee) ; Šteffan, Pavel (advisor)
This work deal with system design and implement of Trip computer for motorcycle serving as information element of speed and fuel consumption motorcycle. The general aim is design of device with graphic display that shall represent measured values of speed motorcycle, rpm of motor, onboard voltage, charging current, motor temperature and ambient temperature. All measuring data will be saving on memory card. For easily tracking in system menu will be used touch panel on graphic display.

Production testing equipment
Vokřál, Jiří ; Musil, Vladislav (referee) ; Hejátková, Edita (advisor)
The thesis introduces the design of a test device for preassembled mechatronic cylindrical locks. The device is designed to test the mechanical and electronic parts which ensure minimisation of loss caused by poor preassembling or defect due to electronic parts. Since the defect will only come to realisation upon the complete product testing, the time of complete dismounting, exchange and assembly of the mechatronic parts would be saved and also time required for the final test of the whole product on the device would be saved.

USB cable tester
Fašanga, Jozef ; Hanák, Pavel (referee) ; Lattenberg, Ivo (advisor)
Measuring low resistances is a problem that also occurs with USB cables. The basic feature influencing the functionality is the voltage drop. The work deals with the theoretical possibilities of measuring low resistances and subsequent realization of connections. The ATmega32U4 microcontroller is used to control the device, which provides a USB interface for programming. Work theoretically discusses individual communications used for OLED display and ADC. Subsequently, the work discusses the design of the box for the device and the basics of the program, which is uploaded to the microcontroller.

Electronic Ignition Unit for Combustion Engine
Čmelík, Matouš ; Knobloch, Jan (referee) ; Červinka, Dalibor (advisor)
Thesis deals with electronic ignition for a two-cylinder two-stroke engines. In the thesis is described the existing ignition system. In the thesis are described measurement options of the position ot the engine crankshaft. The ignition system is designed mainly for motor JAWA, CZ and motor Trabant. The design is focused on reliability of entire circuit. The main advantage of the entire proposed design is possibility to adjustable ignition curve, depending on several external parameters such as speed or temperature of the engine. The proposed ignition has been tested in vehicle Velorex.

Portable music player
Rozsíval, Adam ; Šotner, Roman (referee) ; Dřínovský, Jiří (advisor)
The thesis deals with the project of a portable music player with an amplifier in the class D. The device is powered up by connected power supply unit, eventually by built-in accumulator. Audio signal is played by bluetooth module, sound card or headphone output. Switching inputs and power supply of the accumulator is managed by a micro-controller. A correction equalizer for sound control is also embedded in the booster. All peripheries are put into a wooden baffle board. The sound is reproduced by a pair of loudspeakers.

Harness tester
Smola, Tomáš ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This thesis deals with issue and construction of wire harness tester. In the first place, is this thesis focused on market exploration and comparison of comercial testers with concrete requirements for small batch production. I will try to find a suitable product in worldwide market, which would be convenient for company producing construction machinery. For testing switchboard harness we need to test interconnections between connectors, resistors, relays, diodes, transils and switches in the dashboard. If I can not find some product, I will try to design some new tester. My priorities will be testing all components in harness, maximum flexibility of tester for the future trends in contruction of rollers and user friendly control.

RFID acces system realization
Buchal, Adam ; Matyáš, Pavel (referee) ; Marada, Tomáš (advisor)
This bachelor thesis deals with the use of RFID technology in access control systems in intelligent buildings. The study also describes the principle functions of RFID readers and the list of frequencies at which the technology works. The next section is dedicated to the design of the access system with iClass R10 operating at a frequency of 13.56 MHz, the whole system is controlled by a microprocessor ATmega8. The board design is described program for creating electronic schematics EAGLE. The try-out functionality and basic programming functions used kit EVB 4.3 The last section describes the procedure for the production of printed circuit boards photo path including drawings and schemes and also describes the program controlling the entire device using the block diagram.
