PLC technology in data collection systems
Kolář, Jan ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
This bachelor thesis deals with the use of PLC technology in data collection. The first part includes information about PLC. An analysis of types, properties and types of modulations of PLC focusing on the narrowband one is carried out. Used modems from Yitran company are described. Attention is also paid to creation of software for an application focused on data collection from simple sensors. The thesis incudes the description of two created applications required for the realization of data collection system. In the last part, measurement of packet loss dependence on distance is described. From the measurement it follows that the modems operate reliably with rising distance as well.
