Lab exercise of electronic burglar alarm system with communication over Ethernet network
Harth, Petr ; Pust, Radim (referee) ; Burda, Karel (advisor)
This bachelor thesis deals with electronic burglar alarm systems that communicate over Ethernet network. On this basis, the lab exercise is designed for an integrated security system Xtralis 3000 to ensure access control and camera surveillance. The concept of lab exercise is justified, and prepared documentation for it. Subsequently, a brief analysis of the Xtralis 3000 system security is also made. The first part describes the development of electronic burglar alarm systems. The history as well as current state of the art of electronic burglar alarm systems are outlined. Also camera surveillance systems and access systems, which are nowadays combined with electronic burglar alarm systems, are briefly mentioned. The thesis goes on by describing the current trend of integrating various security systems into one system that communicates over Ethernet network. In the second part of this thesis the integrated security system Xtralis 3000 is being analyzed. First of all its general characteristics are described and then it goes on by explaining the distribution of the three subsystems, namely the access system S3000, the camera surveillance system V3000 and management software M3000. Subsequently, these systems are being described along with their features. After that, selected network protocols, which integrated security system Xtralis 3000 uses to communicate between its components, are being briefly discussed. In the third part a brief analysis of security integrated security system Xtralis 3000 is carried out. This system is divided into six parts in terms of threats of attacks. The fourth section it is devoted to the concept of lab exercise, which includes introductory balance sheet, the debate over the assigned elements, content and structure of the lab exercise. In the fifth part, is the thesis offers documentation to the lab exercise of integrated security system Xtralis 3000 communicating over Ethernet network, according to which students may perform this lab exercise. And finally, in the sixth part are the instructions for teachers, which describe how to introduce the lab exercise in teaching, with the associated problems and their solutions.

Modbus TCP interface
Krotký, Pavel ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
Main puropose of this thesis is to design and develop Ethernet to serial interface converter. Ethernet and serial line protocols are briefly described. Appropriate microprocessor and hardware for realisation of each physical layars were choosen. Convertor uses Texas Instrument's TI-RTOS operating system. Convertor's purpose is to pass on communication between physical layers and also fulfill webserver role with configuration possibilities.

ECG Signal Transmission via Ethernet
Bayerová, Zuzana ; Provazník, Ivo (referee) ; Sekora, Jiří (advisor)
The semestral thesis describes ECG signal compression methods designed to modify the data for transmission via communication channels. The thesis contains an introduction to Ethernet and explanation of communication in the network. The transport protocols TCP and UDP are discussed in more detail. In the practical part of the thesis was created two separate applications. The first application in the sender's computer opens a text file with the ECG signal. Loaded ECG signal is filtered by cascade of filters to eliminate interference. The resulting signal is displayed. A part of the application is the R wave detection, calculating the length of RR interval and heart rate. The application also allows to compress an ECG signal. ECG signal is sent via Ethernet network via UDP protocol for individual samples. Applications in the recipient's computer receives signal samples from the network. Recieved compressed data is reconstructed. The resulting ECG signal is displayed and there are again detected R waves, the length of RR intervals and sampling frequency are calculated.

Laser diodes controller utilizing AVR microcontroller
Boštík, Jiří ; Šilhavý, Pavel (referee) ; Krajsa, Ondřej (advisor)
This thesis deals with the design and subsequent realization of laser diode control devices. The circuit will be able to control the diode with using a laser driver, via a computer network or via the display for control current values, setting of initial values and more. The device will be connected also with a SD card for saving of settings. In the theoretical part there are described individual components that are needed for functionality of the device. The practical part contains a block diagram, in which is described complete feature of the device, then a draft scheme with a description of all integrated circuits and important components. At the end of this work is described the software that controls the entire designed device.
