Vibrodiagnostic system
Bortlík, Pavel ; Čala, Martin (referee) ; Beneš, Petr (advisor)
Thesis discusses bearings failure detection that is manifesting with increased levels of vibration and acoustic emission. The first part of my work gives introduction to common disorders arising on bearings during operation and negative effects on the bearing condition. Further the thesis makes the reader familiar with the terms of vibration and acoustic emission. The work includes a description of available methods for signal evaluation of vibration and acoustic emissions in order to diagnose the state of the bearings in the domains of time and frequency. In the practical part is explained the vibrodiagnostic concept with focus on bearing endurance test. Part of this practical test is a balance sheet for hardware with marginal parametres and a software description. The work is complemented with sorted database of processed topics from the magazine Orbit Bentley Nevada.

Ni sensors to Ethernet convertor
Kubíček, Ondřej ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
This work deals with hardware and software solution for the temperature converter of the standard rezistance temperature Ni sensors with the output through the Ethernet, driven by the Rabbit microcontroller. First part of this thesis deals with the theory of the temperature measurement. There are introduced basic principles of the temperature sensors. In the next part of the work are introduced communication standard and application protocol Modbus. The rest of the work deals with the hardware concept of the converter, the control program of the converter and the program developed for the PC.

Temperature monitoring unit
Martínek, Jaroslav ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
Content of the Bachelor Thesis covers design and realisation of an unit for multipoint temperature measuring in cooling and freezing equipments in food stores and shops. As a controlling microcomputer is used an Atmel ATMega128, temperature sensors are realised by DS18S20 digital thermometers, connected via 1-wire bus. Unit can read temperature from 32 temperature sensors, includes memory for measured data, real time clock, Ethernet interface and display with buttons for basic user control. Temperatures are measured periodically with user defined interval, values are stored into internal memory and showed on display. Measured data can also be transferred via Ethernet to clinent PC, where can be viewed in form of table and graphs.

Datalogger with parallel data logging
Havlena, Marek ; Minář, Petr (referee) ; Zuth, Daniel (advisor)
This Bachelor's thesis is dedicated to the design and implementation of the Datalogger module, which stores data in two different memory storages. First memory storage is solved by using an SD card and the second is the internal EEPROM memory of the microcontroller. It also deals with data synchronization between these memory storages. Communication between the cards is through the SPI bus and communication with the module is provided by a serial interface designed by USB transmitter (UART).

Analysis of Water Consumpion in Faculty of Civil Enginering Campus
Nedoma, Tomáš ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
Bachelor thesis will conduct an analysis of water consumption on the premise of the Faculty of Civil Engineering. There will be a condition surfy of all billing and secondary water meters in the area of faculty evaluation of design options and automatic data collection on these meters. As a further assessment will be made of the current fading status data from water meter installed in the premise sof the Faculty. Own water meter fading using appropriate datalogger including datermination of the average specific consumption per employee, student or other special purpose units. The last point of the thesis will investigace the possibilities for remote measurements with continuous monitoring and data transmission to the internet.
