Data logger for Gas Boiler
Frnka, Peter ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This bachelor thesis deals with design and realization of a datalogger designated for logging data acquired gas boiler controls. The gas boiler controls are under development by Honeywell Brno. The datalogger is implemented on Raspberry Pi hardware platform with voltage converters supplied by Honeywell Brno. Measurement application, which is part of datalogger firmware was developed in C programming language. All data that are measured during datalogger runtime are stored on data storage. The measured data are presented to the user by a web application. The web application and data storage are put into operation on the main server, which is the part of local network in Honeywell Brno. In result of this thesis, data logging system capable of collecting data from furnace controls was developed. Created device helps with research, development and testing of furnace controls.

Design of flight test laboratory for ballistic recovery systems testing
Chadima, Bedřich ; Pejchar, Jan (referee) ; Popela, Robert (advisor)
This thesis is focussed on designing of the air drop labradory for testing the balistic recovery systems. The first part of the thesis describes balistic recovery systems, their parts as well as methods of testing this devices. In the second charter there is a description of older vision of a testing device and simple test with the electronics of the testing device. The next step is designing of the new koncept of testing device and the structure analysis of the frame. The product of the thesis is a modular automated testing device, which is able to test balistic recovery systems for aicrafts with the weights between 230 and 1700 kilograms.

Design of autonomous monitoring system elektronics
Heger, Krištof ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
This master’s thesis deals with the design of autonomous monitoring system electronics which will be used for diagnostics of the electromagnetic vibration generator developed at Brno University of Technology. This generator should be used in a practical application where frequent mechanical shocks are present, for example in vehicle or goods transportation. For such an application, the goal of the monitoring system is to find out whether generator is capable of producing enough electrical energy for smooth operation of wireless sensors used in similar applications. The first part of the thesis consists of the autonomous diagnostics system overview from both commercial and scientific spheres, brief description of the vibration generator used and also a summary of commercially available power management electronics. The next chapters present the detailed description of each functional element of energy harvesting system, the simulation of generator’s behaviour for optimal load in three different model applications and the most important part – design of the autonomous monitoring system. In the end, achieved results are evaluated and it is considered whether the shock-driven generator is suitable for use in a given application.

Smart Metering of Water Supply System at Campus of Faculty of Civil Engineering BUT
Černíková, Eva ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
The aim of this thesis is to perform an analysis of possibilities and benefits of installing the Smart Water Metering technology at campus of Faculty of Civil Engineering, Brno University of Technology. The main goal was to provide specific solutions of Smart Metering systems from different companies. One part of this thesis is dedicated to a detailed analysis of a water consumption measurement campaign that took place at the beginning of this academic year using dataloggers. Real-time flow rate and consumed volume was recorded every five minutes. Therefore it was possible to determine water consumption patterns during the day and also tell the minimum, maximum and average flow rate in different parts of the campus. Thanks to these measurements, irregular water consumption during the night was observed. This would not have been easily detected without recording real-time data. This system of recording real-time flow rates with dataloggers is considered to be suitable for the needs of faculty. Thanks to a GSM module, recorded values are sent to an FTP server once a day. From there the data can be downloaded to any kind of analysis software. Installation of Smart Water Metering technology at campus of Faculty of Civil Engineering would be beneficial for both operation of the water supply network and also for purposes of an academic research.

Analog Signals Datalogger
Ščišľak, Tomáš ; Frýza, Tomáš (referee) ; Vyskočil, Pavel (advisor)
The subject of my bachelor’s thesis is construction of device, which provides measuring and digitally recording of analog signals. The first part of this thesis deals with an analysis of circuit properties and building the basic scheme. It was important to choose proper components available. Datalogger consists of integrated digital circuits, which provide fast and reliable communication path. Function of main unit performs microcontroller Atmega128. The realization of external modules for current sensing looks interresting, particularly implementation of Hall sensor ACS755, circuits HCPL and solution of their connection with the main board. Second part of this thesis is oriented on hardware and software realization.
