Data logger
Dráb, Dominik ; Pazdera, Ivo (referee) ; Ctibor, Jiří (advisor)
This master's thesis deals with design of universal data logging device. The work proposes the design of device architecture and describes individual systems and components, that are necessary for data logging. Logger is designed as a mobile device, with ARM microcontroller at its core. Thesis specifies requirements for device in terms of performance and versatility. The device uses modular construction, as it comprises multiple PCBs. The thesis describes their design and also design of the mechanical construction of data logger. Designed device has been realized and assembled. Software design for microcontroller is also part of the thesis. In the last part, measurements to determine achieved parameters of the device are conducted.
Digitaly controlled inverter for induction motor
Dráb, Dominik ; Klíma, Bohumil (referee) ; Knobloch, Jan (advisor)
This thesis deals with the design of control unit of frequency converter for asynchronous motor, that is part of the laboratory stand. The work contains basic description of asynchronous machine and explanation of operation and design of frequency converters. Furthermore, the work explains the most commonly used methods for control of electrical drives with asynchronous motor. The following chapter describes the design of control module with microprocessor from Freescale. The work also deals with the creation of software for microprocessor. Additionally, the graphical user interface was designed for controlling the stand using a computer. The final chapter of thesis describes measurement of the induction motor.
