Sensor devices emulator for industrial networks
Malček, Ladislav ; Fujdiak, Radek (oponent) ; Blažek, Petr (vedoucí práce)
The task of bachelor thesis is design of sensor devices emulator for industrial networks. Subject of the first part is description, safety and control of electric network. Afterwards the current and voltage sensors and merging units for analysis of data are presented, followed by description of the used microcontroller, and all the individual components of simulator. In the next part the design of circuits for voltage, current and binary outputs is presented. The third part of thesis are designs of control terminal and web interface for setting of simulated values by user. After physical realization of emulator, it was tested on a control device. The last part of the thesis are results of testing.

Design of a BPL modem with an ethernet interface
Malček, Ladislav ; Rusz, Martin (oponent) ; Musil, Petr (vedoucí práce)
The task of the master thesis is the review of selected module PLC Stamp 1200, which provides data communication via power-lines. Subject of the first part is description of PLC communication and its types, especially BPL communication. Afterwards transmission lines, communication interfaces and couplers for injecting the signal into the lines are described. Next, general procedure of design printed circuit boards is presented, followed by specific application rules for prototype BPL modem, especially for RMII and RGMII interfaces. In the second part the design of printed circuit boards for BPL modem is presented. Next, the results of measurement of modem prototype and final device is provided. In the last part of the master thesis, there is a design and results of testing of noise coupler for injection of noise into transmission lines. This device is used for BPL modem testing in worsened conditions.

Evaluation of broadband couplers for noise injection into powerlines.
Malček, Ladislav ; Musil, Petr ; Mlýnek, Petr
This paper deals with the problem of coupling noise into the transmission power line. The main goal is development of device which can effectively inject noise into transmission lines. This device will be used for testing industrial or commercial-used BPL (Broadband Powerline) modems and their ability to communicate under certain conditions. In the first part, there is an overview of coupler types. Next, the appropriate type was chosen according to required qualities. PCB (Printed Circuit Board) design of final device was developed on the principle of capacitive coupler. In the end, final PCB design was tested with several combinations of magnetic coils and capacitors.
