The utilization of wireless modules for data acquisition
 Machů, Petr ; Mácha, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
In the bachelor‘s thesis I deal with modern methods of wireless data transmission in decentralized wastewater treatment. I suggested three different architectures and various types of wireless modems related to them. Then I design the experimental workplace with the convenient architecture for an autonomous network. For data collection I use PLC (Programmable Logic Controller) Foxtrot series with the central unit of CP-1005 and I use two modems Conel CDL 800 operating in the unlicensed band 869 MHz for wireless transfer. In the Mosaic I design a program for reading inputs from wastewater treatment plant and maintenance of serial channel, in Radwin program I configure wireless modems for the point-point transfer. I present Hyperterminal configuration and delivered date are displayed in it. Finally, I design applications in PHP language that converts data into a graphic form. In conclusion, I present opportunities for further development and improvement of the network.
