Security system with mobile comunication
Novák, Petr ; Kučera, Pavel (referee) ; Macho, Tomáš (advisor)
The main aim of this work is to create such an electronical alarm system, which could be used at permanently or temporary inhabited areas or in cars. The advantage of this system is the possibility of the silent alarm, which is carried out by SMS. These messages are sent by to the owner or to the security company by GSM service. The first part of the project tries to solve the problem of guarded areas. It is necessary to deal with this problem, so that the system itself could work correctly. The second part describes the SMS contents and the way of communication between the microprocessor ATmega16 and the mobile phone Siemens C35 by AT commands. Up-to-date price comparison of these services, which are offered by mobile provider, are included in this part. The focus of the third part is hardware realisation of electronical alarm system. This part sloves connecting of battery backup, battery recharging in the mobile phone and analyses single sensors as well. In the last part the suitable algorithm with the help of a higher level programming language C is used for the microprocessor system.

Sensory system of mobile robot
Pata, Jaroslav ; Žalud, Luděk (referee) ; Burian, František (advisor)
This work deals with development and implementation of sensory system of mobile robot. Sensory modules will be connected to the main control unit of the robot. Communication bus should be chosen. This bus must be reliable and extensible. Expected skills: Programming of microcontrollers AVR, desing and production of printed circuit board and knowledge of principles of basic type of sensors.

Wireless data transmission in ISM frequency band using Manchester encoding
Záděra, Zdeněk ; Němec, Karel (referee) ; Zeman, Václav (advisor)
This work is dedicated to the design and implementation of modules for the bidirectional transmission of data in the ISM band (Industrial, Scientific and Medical), used for private purposes, such as the transmission of telemetry data between mobile devices in the field. Delivery is solved by using RF modules RFM12BP the maximum power 500mW, these intelligent modules are controlled with microprocessor companies ATtiny2313 Atmel. Microprocessor is also used for the transfer of serial interface between computers and RF interface module. Utility for microcontrollers is written in C language development in middle CodevisionAVR. The project is designed in cooperation with the staff development center in Brno Honeywell.
