Design and Realization of Device-Prototype for Multi-Channel Monitoring of Measured Quantities via USB
Nevoral, Jan ; Kunovský, Jiří (referee) ; Strnadel, Josef (advisor)
The aim of this work is design and construction of a device based on microcontroller Freescale MC9S08JM60 that will extend laboratory kit used in the lab of Computer Hardware course at FIT BUT. The device allows monitoring of several measured quantities and sending the measured values to a computer via USB. The first part presents the current laboratory kit and used microcontroller. The second part contains device’s design including schematic, PCB and a list of used electronic components, a description of implementation of firmware for the microcontroller in C and control application written in C#. This application receives the measured data samples from the device and visualizes them to demonstrate the functionality of the device. In the last part of the bachelor’s thesis there are proposed steps to upgrade the laboratory kit based on this device, contained its evaluation and possible extensions.

Weight Measurement with Bathroom Scale Strain Gauges
Šenfluk, Petr ; Fuchs,, Michal (referee) ; Povalač, Aleš (advisor)
The aim of the thesis is weigh measurement using strain gauges from cheap digital scales. Work describes problems connected with using strain gauges as temperature compensation and requirements for accurate voltage reference and summarize function and wiring of chaep digital scales using four strain gauges. Result of work is design of an electrical circuit for weigh measurement using four strain gauges from analyzed scale.

Controller of hot runner for injection molds
Chrenka, Eduard ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
The thesis focuses on implementation of a hot runner controller for injection molds for plastic materials with a maximum number of 56 regulated zones. The first part of the thesis deals with already existing and used solutions of the given subject. The following part of the thesis describes the principles of temperature measurement by means of thermoelectric sensors, including their linearization as well as communication protocols MODBUS, EUROMAP 17. The identification of a regulated system ( heating zone) has been carried out before the hardware design. The development process is divided into some parts : system conception, hardware design, software development. The controller consists of measuring modules designed to collect data and handle power controllers for management of performance of heating elements. The necessary calculation power is integrated into the controllling computer. All parts of a hot runner controller are implemented taking into account the costs.
