This thesis is focused on the creation of measuring workplace for remote power supply system. This is the measuring of the workplace, engaged in the processing of measured data, the production of electrical energy made by a photovoltaic panel and wind turbines. In the theoretical part, the reader is familiar with the issue of renewable energy sources. The first chapter is about the energy of the wind. Here is described the emergence of the wind, the basic division of wind power, through the production of electrical energy to the measurement itself. The second chapter deals with the solar energy. This chapter describes the emergence of the solar energy, photoelectric effect, description of characteristic features and related evaluation of the photovoltaic panel. The reader learns the basic distribution photovoltaic panels here and their manufacturing. The third chapter is devoted to measurement methods and specifying the basic conditions for the evaluation of the operation of wind turbines and photovoltaic panel. In the fourth chapter describes the basic data on individual facilities, which have been selected for this thesis and the involvement of the measuring site. There is also included wind power JPT-100 photovoltaic panels A-130 anemometer TX20ETH, pyranometer SG420 and temperature sensor PT100. Measuring software is described in the fifth chapter. In the last chapter, contains the experimental measurements in the selected time interval and the actual evaluation.

Condensing technology and flue gas
Müller, Jan ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This thesis is developed as a proposal for heating for a primary school and kindergarten in the region of Brno-countryside. For the insulated building, a combination of heating and air-conditioning is proposed. The concept is designed so that the air-conditioning preheats the exterior air and the heating system warms the incoming air to a comfortable temperature. For the required thermal performance, sources of heat (for gas and pellets) and a layout solution for the boiler room is designed. Drainage of combustion products is proposed for both solutions. The project solution is per the extent of the construction permit. The theoretical part is linked with the practical part through the condensation boilers, their function and division, and drainage of combustion products. The experiment for the given topic was conducted on the drainage of combustion products. The pressure loss of the reverse knob was determined in relation to the flow rate of air in the condensation boilers as this loss is essential in assessing the drainage of combustion products.

The temperature measurement with semiconductor sensor
Dostálek, Martin ; Klíma, Bohumil (referee) ; Huták, Petr (advisor)
This bachelor work disserts on measurement of temperature using the electronic temperature sensors DS18B20, which are controlled by microcomputer type AVR. This sensors use for communication the 1-wire type data bus. The 1-wire data bus, designed by Dallas Semicondoctor, allows connect more devices to the control unit using two wires. This type of measuring elements offers simple handling for the user. The sensor transforms the measuring data directly to the digital data. The rate of the transmission is determined by number of bits in the resultant value and the sensor is programmable during attendance by the set mechanism (master). The sensor code is consistent with the value of measured temperature. That means it doesn’t require supplemental decoding. The resulting data are worked up and displayed on LCD continuously. First part of this work is focused on the theory of 1-wire element. Further, there is an explanation of the principle of the measuring sensor function and its controlling by the control unit. Next, there is a basic description of the AVR type microcomputers, more detailed description is aimed at the ATiny2313 controller, which is used in this work. The important part is dedicated to the implementation of the 1-wire protocol to the appropriate control unit.

Monitoring and Security System
Felix, Martin ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This master's thesis deals with design and implementation of system for securing and monitoring objects. The whole system is serving as an application getaway between typical TCP/IP network and heterogeneous network containing different end devices such as security cameras, microphones and some sensors (e.g. for temperature measurement). In case of detected event, the notification is created, recorded and the user is informed via administrative front-end. System can be managed from remote location and data from devices can be shown by web interface. Theoretical part of this project concerns with the analysis of different types of connecting devices and sensors and the possibilities of their usage for the monitoring systems along with description of communications protocols for each end device. The next part deals with the cameras interfaces, content analysis and connectivity with central server. Practical part describes methods and techniques used for implementation of system.
