Measuring Software for USB Measuring Card National Instruments
Zikmund, Jiří ; Klusáček, Stanislav (referee) ; Keprt, Jiří (advisor)
This thesis deals with measuring with USB card 6009 from National Industries company. The first part of the project deals with attributes and parameters measuring card. The second part of the project is aimed to programming environment LabView. In the third part of the project is descriptioned program to reading and generating curves, preferences and limits of this program, method of use and its options. In the last part of the project is valorization executed measures.

Workplace for automated conductivity measurement of liquids
Rajm, Martin ; Fialka, Jiří (referee) ; Havránek, Zdeněk (advisor)
Its aim the present Dissertation is to create a workplace for automated measurement of conductivity of liquids. Theoretical part describes principles and methods of measurement of conductivity of liquids and also measurement of temperatures of solutions. The reader is then made familiar with the program and development environment known as LabVIEW in which the measurement software has been created as well. This software serves also for the control of the LCR meter “HIOKI 3532-50” whose characteristic properties, control method and possibilities of measurement are briefly characterized in subsequent parts. The text includes also a mention about the GP-IB bus, thanks to which the LCR meter is able to communicate with PC. The actual liquid which is to be analyzed comes into contact, however, only with the four-electrode conductivity cell “WTW TetraCon 325” which is described in the Dissertation as well. The theoretical part is concluded with presentation of the multifunction card “NI USB-6008”, with the help of which the temperature of the solution analyzed is determined. In the practical part is description of the connection and explanation of the function of the measurement system as a whole. This is followed by a presentation of the actual measurement software intended for conductivity measurement. Both its structure, functions and some information about control are described there. This part of the Dissertation deals also with determination of the values of the elements of the conductivity probe replacement circuit and with the impact of measurement parameters on resulting measurement values.

Laser vibrometer with 2D scanning system
Rajm, Martin ; Klusáček, Stanislav (referee) ; Havránek, Zdeněk (advisor)
This thesis deals in the theoretical part with the non-contact vibration measurement by single point Laser Doppler vibrometer and it concretes constructions used in practice. It deals also with the possibilities of the laser beam scanning to measure the vibrations in the plane and there are also listed suitable-commercial systems for this solution. Mentioned sweep is immediately necessary for 2D scanning vibrometer construction. In the practical part, the single-point laser vibrometer OFV-5000 was expanded by scanning galvo system, supplemented by a measuring cards for signal acquisition from the vibrometer and suitable control hardware was chosen for mentioned laser. For the resulting hardware assembly was designed and implemented in LabVIEW measurement software, to control the 2D scanning system, to set the position of the laser beam and to process and to visualize of measured vibration signals in the plane. The functionality of the developed measuring system was checked by performed measurement and visualization of the velocity vibration of restraint girder, excited by shaker.

Application of a measuring probes in milling proces on CNC machine MCV1210
Horáček, Kryštof ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
This diploma thesis focuses on the application of measuring probes in the machining process. The main goal of the thesis is to create sample procedures for measuring cycles and functions in a CNC machining process using MCV 1210 and selected measuring software. In the first part of the thesis available methods of machine measurement are outlined with a great emphasis on the description of measurement principles, construction, and measurement signal transmission methods between tool probes and the workpiece. The second part of the thesis deals with the application of measuring probes in the machining of the designed test piece using the Productivity+TM and Sinumerik ShopMill softwares. The work also includes an economic evaluation of the profit of an investment in the mentioned measuring equipment.
