Řídicí a signalizační jednotka pro sportovní utkání / Control and signalling unit for sport match

Bohutínský, Jaroslav January 2010 (has links)
The aim of this study is a design of a control and signalling unit for sport meetings controlled by a microcontroller. The unit should display the time, the state of the match, eventually another data important for a course of the match. It should be fitted by an audible alarm of the end of the match. A touch control panel with a liquid crystal display serves as input of control data. The unit operates in a countdown mode, it is possible anytime to start or to stop the time by pressing the button. The equipment is mains-operated and backed up by an external battery. In the case of a power failure, it is switched over to the battery. A representation of the time, the state of the match and other data is done by LED displays. The unit allows a connection to PC.

Bezkontaktní měření otáček ventilátoru / Contactless measuring ventilator-revolution counter

Pokorný, Aleš January 2010 (has links)
This project is about design of contactless measuring ventilator - revolution counter. The counter serves to measurement of the speed of ventilator. The measurement is based on optical method of receiving the reflected laser beam. To measure and calculate use the revolution counter the microcontroller. This measured value is diplayed on LCD. After design follows experimental measurement.

Komunikační modul pro řízení laboratorního zdroje / Communication module for power supplies controlling

Zachar, Jiří January 2010 (has links)
The aim of this work is to design a communication module for laboratory source Manson. This power supply communicates only through a serial RS-232 link. Modern computers usually use for the connection with other peripherals mainly USB. Designed communication module contains converter between the RS-232 and USB. Power supply is used in the automated measurement setup, which is controlled from the Virtual Engineering Environment from the Agilent Technologies. Direct commands for laboratory source Manson are not compatible with the SCPI (Standard Commands for Programmable Instruments) standard commands. So, the communication module converts commands from the SCPI format to Manson supply instructions. The communication with the Manson supply will be obvious for students by using new communication module.

"Smart" tester a nabíječka akumulátorů / Smart accumulator tester and charger

Mílek, Čestmír January 2010 (has links)
Nickel cadmium and nickel metal hydride accumulators sets are currently used for supplying hand tools (screwdrivers,...). Problems of cheap hand tools are chargers, mostly of it doesn’t use any charging driving circuits. In consequence of it the accumulators are kept incorrectly, which causes lowernig of lifetime. This thesis suggest circuit design Main of intelligent charging system, which enable better battery management, increases battery lifetime and lower load of environment.

Řídicí a senzorický systém malého průzkumného mobilního robotu / Control System of Small Mobile Robot

Rysnar, Jiří January 2011 (has links)
This master’s thesis elaborates on the control of a wheeled mobile robot and its sensor system. The sensors provide information about distances of obstacles in its surroundings and orientation in area. The communication is realized by radiomodems, commands and data are sent by serial link between microncontroller and the PC.

Systém řízení světelných zdrojů po silových rozvodech / Light system control via powerline communications

Rumíšek, Tomáš January 2012 (has links)
The thesis deals with the design and implementation of smart house lighting. In the living parts of the house, the light intensity is maintained at a constant level which is set by the user. The intensity of lighting can be set manually for each room from a central module with a user interface. It can also be changed by any remote control directly in the room in which the user is currently located. When the remote control is used, the information about the change of light intensity is transmitted to the central module. For communication between the central module and the luminaires, the existing power lines are used.

Elektronický monitorovací systém pro motorová vozidla / Electronic monitoring system for motor vehicles

Pospíšil, Martin January 2012 (has links)
This thesis is about construction of a monitoring unit for motor vehicles. The unit is equipped with microcontroller, graphical LCD for displaying all measured values, GPS module and SD card slot. For measuremet of motor RPM, various methods of connecting to the motor are supported. Temperature is measured with few DS18B20 sensors, picking up engine temp, outsider and inside temp. GPS module is for measuring speed and height above MSL. All measured values can be recorded on SD card for future analysis on PC.

Bezdrátové rozhraní pro digitálně řízené aplikace / Wireless interface for digitally-controlled applications

Valouch, Martin January 2012 (has links)
The thesis aim is in practical realization of wireless interface, which is created by infrared relay in motorcycle Simson. Infrared relay is used for speed measuring. This work describes the realization of digital controlling by microcontrollers. Digital controlling can easily improve and upgrade functions for better driving comfort. It’s possible by getting information about condition of selected motorcycle parts. This information can be engine temperature, battery charge, total distance and etc.
