Palubní počítač s testovací jednotkou pro osobní automobily / On-board Computer Unit with Testing for Cars

Špatenka, Jan January 2012 (has links)
This thesis deals with the design and implementation of on-board computer unit with testing for cars. The first part focuses on circuit design concepts. Measurement data acquisition module uses standard OBD2. The module is designed based on the measuring circuit STN1110. Measuring module equipped with USB and JTAG communicates with the nearby devices. The control module is equipped with ARM microcontroller. The second part deals with the implementation of software for the microcontroller and the PC application. Finally, test results of the on-board computer implemented are presented.

Interface diagnostické sběrnice pro akumulátory / Accumulator diagnostic bus interface

Chytka, František January 2013 (has links)
The thesis deals with design and construction of diagnostic device for batteries. In the analysis I described and compared well known I2C bus and quite similar SMBus. The latter bus is used in the laptop batteries called Smart Battery. The design includes the USB bus, which I described briefly in analysis too. I suggested a several designs, discuss them and build the best one of them. The realization of the diagnostic device includes construction aspect and programing aspect. Both aspects are described in the thesis. At last, the results of test diagnostic of several batteries carried out by designed device are introduced.

Chybové frekvence ložisek / Bearings Error Frequencies

Životský, Petr January 2008 (has links)
This dissertation deals with error frequences of bearing because the bearing is part of every rotary machine. Certain type of bearing and caused defect is being compared with error frequences which are acquired by experiment. Various kinds of measurement which are more or less applicable in use are being described. Further the dissertation deals with other possible ways of detection error frequences for particular defects of bearing.

Úprava zkušebního zařízení ložisek pro aplikaci metody akustické emise / Modification of experimental arrangement for bearings testing for application of acoustic emission method.

Suchanek, Daniel January 2009 (has links)
Master’s thesis is focused on modification of experimental arrangement for radial ball bearing contact endurance testing so that the diagnostic method of acoustic emission could be applied. There is an assumption that AE method is able to identify damage to bearings in earlier stages than the vibration diagnostics. Design modifications also allow the addition of modern vibrodiagnostic equipment to a system.

Diagnostické metody sledování plynů rozpuštěných v transformátorovém oleji / Diagnostics Methods of Dissolved Gas in Transformer Oil Observation

Hindra, Matěj January 2012 (has links)
This thesis is devoted to analysis of the diagnostic methods used in practice. It is divided into two parts: theoretical and practical. The theoretical part concerns with the general description of the transformers. Further it provils informatik about systems for sampling oil from transformers with insulating oil – paper system. Another important part is the description of gas chromatography and TRANSPORT X. Description of the most appropriate evaluation methods for assessment of the state of the transformer is included as well.

Analýza jízdních vlastností motocyklů / An analysis of motorcycle driving properties

Janovec, Ladislav January 2012 (has links)
This thesis deals with evaluating methods of vehicle driving characteristics with focus on dumping units analytical assessment. In theoretical part thesis describes some of today analytical methods used in practice and in experimental measurement. Analytical methods allow objective evaluation in the assessment of driving characteristics. Main objective of the thesis was to formulate two independent methodical procedures for analyzing motorbike driving characteristics with the subsequent practice verification.
