Měření teploty s přenosem dat přes sít WLAN / Temperature measurement with data transfer via WLAN

Müller, David January 2014 (has links)
This diploma thesis deals with the design of temperature sensor and display units, which communicate via a WLAN network. The theoretical part provides an overview of various methods of temperature measurement including several specific types of temperature sensors, and also introduces the WLAN standard as well as TCP and UDP protocols. The design solution is focuses first on the system architecture and design of the communication protocol, followed by the implementation of both types of equipment, starting with selection of components, through design diagrams and printed circuit board patterns, up to production and commissioning. The following parts of this thesis deal with the design of programs for the controlling microcontroller units of both units and the configuration application for PC.

Systém sledování stavu konstrukcí z inteligentního betonu / The monitoring system for smart concrete construction condition

Brouček, Jan January 2015 (has links)
This thesis describes designing of a wireless system which allows to transmit measured data of sensors made of smart concrete. Measured data are transmitted from measuring points to the collecting unit, which stores them, and pass them to the server which is connected in the Internet network. The design of the system is focused to achieve low power consumption of all used components to provide the longest possible operation time, when using primary lithium cell. The design should be also able to provide possibility of easy modification of the measuring points.

Robot pro stolní tenis / Table tennis robot

Nguyen, Thuc Tuyen January 2013 (has links)
This diploma thesis deals with designing and manipulating a robot for training table tennis. Robot's mechanical construction is based on aluminium profiles supported by various standardized assembly units, such as rotating bearings, plain bearings, threaded rods... The front-end part of the robot, which requires better deformation property and lighter weight, was made from ABS material using 3D rapid prototyping technology. The design of the robot allows its body to rotate around three axises. Thanks to the high dynamical ability, robot can be set to throw balls to various places on the playing table, with different types of ball spin. Balls will be shot out by two rubber wheels, which are attached to two electrical DC motors. By driving the speed of the two motors, we can control the speed of the ball, as well as speed of its spin. All robot's activities are driven by an embedded system designed using microcontroller ATMega128. A firmware for controlling robot's function was writen and flashed into the microcontroller. End-users might communicate with the robot via a system of buttons and a text LCD display. The built robot was tested and it has shown its ability to throw balls to 6 different places of the playing table, at different speeds, with different types of ball spin, and different spin speed, according to the parameters set by user.
