Wireless M-Bus communication system
Baštán, Ondřej ; Šťastný, Ladislav (referee) ; Fiedler, Petr (advisor)
The thesis deals with the design of wireless communication system using Wireless M- Bus, which works in the 169 MHz band. This system is designed to collect data from meters that are not equipped with a radio and have pulse outputs. The thesis describes the Wireless M-Bus standard and the current components of the communication system used by ModemTec. It also describes the selection and design of a suitable hardware implementing the receiver and transmitter modules and the firmware design for these modules. The thesis deals with the parameterization of the transmitter module in order to specify the parameters of the transmitted measured quantity.

Automatic switch between mains and accumulator power supply
Šišák, Dalibor ; Číž, Radim (referee) ; Kubánek, David (advisor)
This work deals with the solution of automatic switch between mains and accumulator power supply. For simplicity, versatility and variability of the device is controlled by a programmed microcontroller from Texas Instruments series MSP430G. Because one of the requirements is supply the device from battery power, the work deals with a design of the device, but also the selection of appropriate components with favorable characteristics such as low self-consumption or power dissipation. It also discusses how to protect the switching elements and the entire plant, converter for solar battery charging and the possibility of interaction with the user in the form of an information display and keyboard.

Miniature Tracking Device
Šťáva, Radek ; Levek, Vladimír (referee) ; Macháň, Ladislav (advisor)
The main theme of this masters's thesis is to design and make a miniature universal tracking device. This device is primarily for tracking asset, pets or people. For detecting the position data is used GPS technology. Data transmission is carried out via the GSM network. The device is technically solved and realized with respect to miniature size, high battery life and with regard to resistance against water, dust and impact damage. It is selected unique design, suitable for hermeticaly closure of the entire facility. Due to hermetic closure there is any buttons, any connectors and the battery charging is wireless.

UDP a TCP Communication for FITkit
Musil, Martin ; Strnadel, Josef (referee) ; Vašíček, Zdeněk (advisor)
The aim of this thesis was to extend educational platform FITkit for the possibility of communication via TCP and UDP protocol. Communication is provided by Ethernet module ENC28J60 from Microchip. Communication protocols are provided by library enc28j60, which is implemented in C language. The theoretical part deals with analysis of network protocols to be implemented. Work continues describing the characteristics and parameters of the connected module. Followed by a design library in which is particular emphasis on limited computing resource of the platform. In the implementation of the work is to describe the application interface and the basic principles of the library.
