This master thesis discusses design and realization of a security device for vehicles. This device can determine its actual location, discover unauthorized trespass and send information about this to a distant master system too. This distant master system can show the exact position of the security device on a map. The hardware and software for this security device and the software for the master system are described in this paper.

This master’s thesis contains a basic description of the function and wiring of Electronic tachograph RE1xx from company UniControls - Tramex. The main objectives of this thesis are design and implementation of a functional module, combining the four frequency inputs, two analog inputs and eight digital inputs. The proposed module must be fully compatible with current system of Electronic tachograph and must be according by the basic technical-law standards, which refer of this branch for application this device. Based on the analysis of methods of processing various signals are proposed several concepts of the input module. Individual concepts are described with advantages and disadvantages. On the design concept of this module, followed by a description of the speed sensor, is placed on the redress of vehicle. Design of circumferential involvement of the chosen conception is detailed described and divided into several parts (controlling part, frequency inputs, analog inputs, binary inputs). In this module is accent on increased reliability and interoperability, which is achieved by using for example: power monitor, external watchdog, etc. For realization prototype is a part of thesis design of the PCB. Thesis includes theoretical calculations, which is needed for the design of software. On a functional input module is developed and debugged operating firmware, which is based on single-fiber design of the program. To measure the actual speed are debugged two algorithms - method of periodic sampling and the method of external interrupt. The following is a description of the measurement and processing of analog and digital signals (used algorithms suppress oscilation of input signals). The result of this master’s thesis is functional Module of frequency, analog and digital inputs, which measures vehicle speed, distance covered, direction of movement, two analog signals and evaluates states of the binary signal. Preprocessed data are sent to a Module of central processor through serial communications RS485.

This thesis deals with the design of the 3,5" floppy drive emulator with ATMEGA microprocessor unit. The emulator has been designed according to the principles of designing electronic devices, there is also object-control application and firmware for a microcontroller, which supports MFM coding. The thesis also lists all the formats of data stored or transmitted along with some flowcharts.

Laboratory push – pull switching power supply with symetrical output 2x0-30 V/5 A, primarily through adjustable controls (buttons, rotary encoder position) and then displayed on the alphanumeric LCD display. Management and communication device between the user and the power supply of the microcontroller ATmega32 - 16PU.

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.

This work deals with designing complete equipment of paludarium. Selection of individual components to simulate jungle conditions and automate the process of maintaining the forest conditions in a closed environment. All components of the project will be automatically controlled to maintain a user-set conditions inside paludariums. The measured data will be stored on the SD card.

This thesis is pointed on draft of controller unit, used for control of swimming pool with solar collectors. Controller detect water temperature in a pool and collerctor. With these values controller control pump activation and 3-way valve position. Operator can set all settings in user interface which are needed for a right working. Controller unit attempt minimize energy used for a pump while working.

The Diploma thesis describes the design, manufacture and testing of a universal automation machine for church bells. The research section summarizes the bell, way of use and properties. The drives and their starting and power switching characteristic are analyzed. The chain drive based on the selected engine and the whole assembly is designed and tested by using PLC. Unique controller based on a modular design was designed. Sensors based on magnetic rotary encoder were also created for this unit. The entire circuit was tested on three evangelical church bells in the town Klobouky u Brna.

This master thesis deals with a data remote transmission by means of SMS and GPRS technology. The overview of current solutions is presented and then a remote temperature measurement and a data transmission employing a communication module GSM/GPRS TM1 through GSM network using GPRS technology is described. As a response to an impulse, the communication module sends SMS. The technical solution is described in details including HW and SW design of the data transfer and processing equipment using a ATmega 162 microprocessor. This equipment communicates with a server (PC), which displays the measured temperature. A prototype which was used for a validation of the design is also described.

The work deals with implantable devices and possibilities of interference of elektromagnetic field. At first, the electromagnetic compatibility is discussed. Basic terms are explained, followed by insisting on resources of possible distrurbing of implantable devices and standards dealing with this issue. Furthermore, short chapter about devices affecting function of implantable devices is introduced. It means devices which patients with implantable devices may meet in common life, as well as devices used in common life, also devices used jn medical environment. In the next part, measuring process of electromamagnetic effect in working compartment of FN Brno magnetotheraphy and elektrotheraphy is devised. There is a concept of measuring card thanks to which impulses of implantable devices are measured. Finally, a description of measuring on implantable devices in FN Brno. MIKULA, D.
