Wireless sensors for security alarm
Chromý, David ; Burda, Karel (referee) ; Krajsa, Ondřej (advisor)
The goal of the semestral thesis is to get acquainted with the problems arising from the use of low-power wireless devices. For this reason, in the theoretical part, the most used wireless technologies of today are described.
BPL modem
Chromý, David ; Mlýnek, Petr (referee) ; Musil, Petr (advisor)
This work deals with the issue of PLC with a focus on BPL technology (Broadbandover-power lines), which is explained in the theoretical part. The work describes in detailthe main components for PCB design with manufacturing and mounting process. Fur-thermore, the thesis provides instructions on how to establish communication betweenBPL modems and a description of individual functions. In conclusion, the procedureof measuring the noise intensity in the 230 V power line is described with the results.The output of the diploma thesis is the selection of components and the implementationof printed circuit boards for two BPL modems. These modems allow to measure SNR(signal to noise ratio) at physical speed.
