Methods of analysis of vibration signals
Russ, David ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
The main target of this master’s thesis is to focus on methods of analysis of vibration signals in electric machines. To get know the basic principles of the diagnostics methods, is important to clarify origin of the vibration signals and the impact they have. The selected methods were tested practically by measurement on electric machines. Measured data were processed in program LabVIEW. In this thesis were created programs which actually can be aplicated for complete vibrodiagnostics of electric machines in particular induction motors. The basic evaluation of vibration are the RMS value, Crest factor, time course and power spectrum. Results of this thesis are used to demonstrate how quickly and effectively can be vibration signals from electric machines evaluated.

Design of software single purpose machine for manufacturing test
Janoušek, Roman ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This diploma thesis deals with design and implementation of software for control of manufacturing tests of pneumatic proportional valve Festo MPYE. The single-purpose testing device consists of a DAQ device, a pressure sensor and of electrically operated pneumatic valves. In the introduction of this thesis are outlined aims of thesis followed by introduction to single-purpose assemblies commonly used in practice. The main part of this thesis deals with analysis and with solving the issues of assigned product testing. The designed and implemented modular software for control of manufacturing tests of assigned product is presented as an outcome and this software is easily adjustable for tests of a different product. In the conclusion are assessed achieved aims.

USB Measurement Module for Virtual Instrumentation
Hanuš, Ivan ; Beneš, Petr (referee) ; Havránek, Zdeněk (advisor)
The objective of this thesis is design of the universal USB measuring module for virtual instrumentation. The module is connected to PC via USB interface. The module have analog inputs and analog outputs. The inputs have some switchable ranges, adjustable high-pass and low-pass fiters. Also the module have the digital input-output unit with 8 channels with configurable data direction and voltage level. Physical layer for digital serial interfaces SPI/UART and I2C is also part of this unit. The module is able to communicate with LabVIEW enviroment. The teoretical part contains survey of the commercial USB modules for data acquisition and generation from various manufacturers with its basic parameters. Some selected modules are described in detail. Furthermore the thesis deals with possibilities of connecting the USB module with the LabVIEW enviroment. The practical part deals with the design of input-output circuits and with design of the module itself. Furthemore, tho communication protocol, utility library and demonstration LabVIEW software are described in this part. At the end of this part, there are results of verification measurements. The result of this thesis is completed universal USB measuring module with utility library and demonstration program.

Laboratory exercise for a control theory courses
Kozumplík, Miroslav ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
This work deals with a design of laboratory tasks and laboratory hardware for laboratory control. Laboratory equipment contains heating element placed in a pipe. Temperature sensors measure the current air temperature in the pipe. The heating element with the temperature sensors are connected to the computer through the DAQ USB-6001. The signal is read by Simulink program that will be used to design controllers for this system.

Logging application Mnemosyne
Pizur, Jaroslav ; Šedivá, Soňa (referee) ; Pikula, Stanislav (advisor)
The goal of this bachelor's thesis is creation of an application called Mnemosyne, which will be able to measure different types of measurement on each of NI 9219 four input channels. The application can log the data to a TDMS file and at the same time is able to write parameters and settings to its header. Thus every measurement is fully documented and application is able to reproduce any measurement by loading the header of any previously created file. The application is then tested for two different types of measurement on two distinct channels.

Automatic measurement of induction machine using LabVIEW
Halfar, Lukáš ; Huzlík, Rostislav (referee) ; Bulín, Tomáš (advisor)
The main purpose of the thesis Automatic measurement of induction machine using LabVIEW was to develope an automated measuring system, which is used to perform tests of induction motors. The algorithm of the system is programmed in LabVIEW. In the practical part of this thesis, a measurement of the motor Atas Elektromotory Náchod a.s. T22VT512 is carried out, in order to verificate functions of the algorithm, and to perform tests of the motor to analyse losses. Another part of the work is dedicated to the electromagnetic calculation of the motor T22VT512. For this purpose, two softwares with different principles of calculation have been used. Firstly, the calculation is solved by an analytical based software called RMxprt. Secondly, the software Maxwell 2D is used to make the calculation of electric and magnetic fields by the finite element method.

Návrh a realizace výukového modelu Závaží na pružině
Mikulenka, Ondřej ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
This thesis deals with the creation of an educational model of a mass on a spring. The model's construction includes a sensor and an actuator for system excitation. A data acquisition card has been developed to control the model. The parameters of the simulation model were determined based on measured data. The work includes demonstrative exercises for teaching purposes. It provides a comprehensive approach to the "Mass on Spring" model.
