Automation control of measurement setups by web interface
Živný, Jaroslav ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
This master thesis describes issues of measurement workplaces with accent at automatic control of them over web interface. The interfaces, which allow us to control measurement devices, are one by one described. Additionally there are described technologies which were used for realization of web application, as ASP.NET, AJAX, AngularJS, and relation databases. Last but not least there is described solution of web application which allows to users to do automation measurements from anywhere by web browser.
Experimatal Analysis of Windshield Wipers Motors
Dočekal, Martin ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The work deals with the methods of measurement of small DC motors, especially motors used for drives wiper’s mechanisms. Furthermore, describing the internal structure and function of wiper’s engines. Measurement of these engines is carried out mainly dynamometers which is described in more details in the work. However, measuring systems consist not only from the dynamometer but also many other components such as controllers, software for testing engines, various stands, temperature and speed testers, and many others. These components are taken into account, when selecting the most suitable measuring system. There are also various systems analyzed and compared in terms of both technical and economic parameters, but also in terms of measurement options, such as immediate viewing characteristics on a PC monitor of the system assembly, the possibility of measuring the friction torque, efficiency, heating, etc. In conclusion, there is a recommendation of measuring system which I chose as the best option according to its parameters.
The realization of measurement workplace for simulation and testing of AD converters
Panáček, Jiří ; Fujcik, Lukáš (referee) ; Háze, Jiří (advisor)
The objective of this thesis is a design of a development kit, which is used in laboratories during the lessons of Theory of analog to digital conversion subject. This device is adapted for basic measuring and understanding of digital to analog (D/A) and analog to digital (A/D) converters and contains sigma-delta A/D converter made of basic elements, D/A converter with R-2R resistor net, active low pass frequency filter (Sallen-Key), PWM generator, SAR A/D converter with 16 b resolution, reference voltage source and module for measuring integral and differential nonlinearity of A/D converters. The modules are available connect to each other via jumpers and they are driven by microcontroller. This solution gives various modes of operation, which can be selected by user via buttons. Development kit has five BNC connectors for securing connectivity to an oscilloscope or a signal generator. The device also contains universal serial bus connectivity for use with personal computer or laptop, which is really useful with Matlab software for automation processing of measuring.
