Measuring unit of electric power quality
Teplan, Miroslav ; Mrákava, Petr (referee) ; Mlýnek, Petr (advisor)
This thesis describes the parameters of electrical energy with a focus on low voltage characteristics and their measurement with respect to the parameters required by standards. In addition, one chapter deals with monitoring of the quality electric energy. Measurement organizations, calculation of power quality and the data collection for its calculation is referred here. For the illustration, the example of a distributed monitoring system from practice is described. The second part deals with the design and implementation of a module for measuring power quality , namely by measuring the voltage characteristics. It describes the selection of the chosen solution, hardware part and firmware for the MCU. To display the measured data, application was created by the Java programming language. The application allows the visualization of the voltage measured Low voltage grid with single phase voltage RMS value 230.

Web interface for a measurement module
Łabudek, Daniel ; Kuběna, Tomáš (referee) ; Zezulka, František (advisor)
The work solve the design and implementation of web application to measure analog inputs, setting and measuring the digital input and output of the measuring module based on microcontrollers ATMEL ATMEGA64. For connecting to internet is use a module LanReach by company Connectone. Measured values are displayed on the website or send via e-mail messages.

Interned based measurement system
Dobrovolný, Petr ; Kozák, Tomáš (referee) ; Zezulka, František (advisor)
The work is deal with the measuration and distribution of data using microcontroller ATmega64. The measuring system connect is done by Ethernet controller ENC28J60 in communication networks. Communication protocols TCP / IP are taken advantage of transfer data to user. Data view is dealt with the HTTP protocol through the use of HTML code. Web browser are used for disclosure of information. Web page uploading can be replenish with current analogue and digital values using the tags created for this measuring system.
