Security system for family house
Sohr, Martin ; Macháň, Ladislav (referee) ; Jaroš, David (advisor)
This thesis deals with complete theoretical design of security system for a family house, from the selection of technologies, security principles and selection of elements, theoretical suggestions of their placement to practical realization. I this thesis, securing of entry points, such as doors and windows, is done by magnetic contact sensors. Windows are secured also against breaking of glass. Inner space is secured using motion sensors. Further, the function principle of optical latches as secondary securing element of inner space is explained. The designed security system implements a central control unit, which is able to provide status information on all security elements to the host system. IQRF wireless communication operationg in licence-free is used for communication among elements of the security system. GSM SIM9000 module is used for communication with the security system.

Design of the wireless sensor and communication network
Ptáček, Zdeněk ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
The thesis deals with the study of the existing wireless network types, propose and realisation of a dedicated wireless network based on using nRF24L01+ wireless module. The aim is to design a simple, reliable and multifunctional low-cost wireless network. The cellular tree topology and random retransmission delay are used to eliminate cross-talks. Low propagation time is achieved by using ALOHA Access Protocol. Network units cooperate with peripherals in order to measure temperature, humidity, illumination level and other. The power down mode is used to increase duration of battery powered network unit. Practical part of the thesis is focused on creating a computer program to control and set up the network. The network provides a central or autonomous mode.

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.

Wireless communication link analyzer
Dostálek, Jakub ; Burian, František (referee) ; Jílek, Tomáš (advisor)
The aim of this bachelor thesis is to design and implement a wireless communication analyzer in mobile robotics, using IPv4 protocol and Ethernet interface and to create correctly selected and expressed characteristics from the measured data, according to which the wireless communication channel can be further optimized for the best data transmission. To meet these requirements, a brief search of existing solutions was performed, their applicability was discussed and important parameters of the wireless transmission channel were defined, which will form the given characteristics. Furthermore, the actual design and implementation of a wireless communication link analyzer for previously specified required parameters, verification of its functionality on the transmission link with known parameters and automation of measurement and data evaluation was performed.
