Finding the network architecture for alarm transmission system LAN-RING
Mikšíček, Pavel ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This master’s thesis deals with a complex solution for the visualization of network topology. The first part of thesis describes the operation principle of LLDP protocol, which was chosen as a tool for retrieving informations from network traffic based on the requirement of the assignment. There is a detailed description of the LLDP protocol implementation in C language to METEL s.r.o. network products. The second part deals with possibilities of graphical interface in software SIMULand intended for managing network devices. It describes tools expansion process for the visualization of the network topology. In conclusion, the results of testing final solution are introduced.

Power line channel simulator
Jedlička, Tomáš ; Fujdiak, Radek (referee) ; Mlýnek, Petr (advisor)
The master’s thesis is focused on the analysis and modeling of power line communication with aim to implement power line channel simulator in the programming environment Matlab. At the beginning of the thesis are summarized basic information about the PLC communication, its basic distribution in terms of frequency bands and are also mentioned advantages and disadvantages. The emphasis on the meaning and importance of modeling with the aim to analyze PLC communication channel is specified further. The following is a detailed description of the current power lines communication models. Power line channel simulator was created on the basis of mathematical analysis for low-voltage (LV) distribution networks. The created simulator uses a model of cascaded two-ports and works in random or fixed mode. Input parameters are real topologies, different types of loads and cables. RLC resonant circuit as a frequency selective impedance is also included in impedance models. Based on the obtained results was performed the analysis, determined the critical parameters and extreme values. Comparison of effectiveness of created simulator was processed on the basis of available simulators from other authors. Two versions of simulator were created using the results obtained under comparison of effectiveness. For comparison was also performed real measurement on a simple topology. The experimental measurements results have been implemented in the simulator.

Design of the user-friendly touch screen GUI and a physical connection to an existing simulation hardware device
Husar, Jan ; Kaczmarczyk, Václav (referee) ; Štohl, Radek (advisor)
Práce uvádí základní informace o průmyslové sběrnici AS-Interface a popisuje její funkce. Dále se zabývá rozšířením stávajícího FTZ AS-Interface Slave Simulátoru o dotykový display, který značně usnadní ovládání tohoto simulačního nástroje. Je zde nastíněn návrh a řešení uživatelského dotykového rozhraní k tomuto simulátoru s použitím Amulet LCD modulu STK 480272C. Vývoj tohoto rozhraní je proveden pomocí GEMstudia, softwaru firmy Amulet Technologies a grafických programů. Dále tato studie pojednává o softwarové úpravě FTZ AS-i Slave Smilulátoru. Jedná se o úpravu řídícího FPGA v jazyce VHDL zajišťující komunikaci s dotykovým displejem. Poslední kapitola se týká problematiky spojené s návrhem uživatelsky přívětivé aplikace.
