PDA software pro robotický fotbal / PDA software for robot soccer

Uhlíř, Luděk January 2008 (has links)
Robotic soccer is a game like a real soccer but here the game is played by robots. The rules are the same, only there are few exceptions (foul, penalty kick, stalemate situation). Game is running without the human intervention. Just a human referee is supervising the game. Two teams are attending the game. Each of them has a control computer. The control computer is the brain of the game. It has a camera, it is making decisions for the next step of robots and sending them configuration data. The thesis deals with testing of communication interface and designs the new communication protocol for the next generation of the robots. The testing is provided by pocket pc Palm TX. It will send data over the Bluetooth interface to the control pc and will configure particular constants, like constants of PID regulator and an address of a robot. This will be provided by the IrDA interface.

Návrh a realizace bezdrátového interface ODBII-XBee / Design and realization of wireless interface ODBII-XBee

Zatloukal, Martin January 2010 (has links)
This master’s thesis describes possibilities of usage of ZigBee communication protocol and integrated circuit ELM 327 in problem of realization universal diagnostic device, running by OBDII communication standards, which can be used to monitor function of all car´s electronic systems. Thesis also deals with design and realization of necessary electro technical devices and modules followed by compilation of control software and experimental measurements of these devices in real traffic flow. In the first part of project, there are reminded some basic features and parameters of OBDII, followed by description of ways how to use OBDII and adumbrating how to realize universal diagnostic system. The analysis of ZigBee system focused on XBee circuits follows. Construction, ways of data transfer and possibilities of controlling are described. Integrated circuits produced by ELM Electronics Company are introduced and possibilities of usage ELM 327 are described as requested by main task. Second part talks about designing of electronic circuits of this system, assembling schematic diagram and designing sources for production of PCB. Physical realization of these circuits and its first start is also included. Thesis finishes by dealing with practical experiences and measurements using real vehicles. This part talks also about means to improve system by several software solutions to reach more effective functioning of created device.

Plant Level IIoT Based Energy Management Framework

Koshy, Liya Elizabeth 05 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / The Energy Monitoring Framework, designed and developed by IAC, IUPUI, aims to provide a cloud-based solution that combines business analytics with sensors for real-time energy management at the plant level using wireless sensor network technology. The project provides a platform where users can analyze the functioning of a plant using sensor data. The data would also help users to explore the energy usage trends and identify any energy leaks due to malfunctions or other environmental factors in their plant. Additionally, the users could check the machinery status in their plant and have the capability to control the equipment remotely. The main objectives of the project include the following: • Set up a wireless network using sensors and smart implants with a base station/ controller. • Deploy and connect the smart implants and sensors with the equipment in the plant that needs to be analyzed or controlled to improve their energy efficiency. • Set up a generalized interface to collect and process the sensor data values and store the data in a database. • Design and develop a generic database compatible with various companies irrespective of the type and size. • Design and develop a web application with a generalized structure. Hence the database can be deployed at multiple companies with minimum customization. The web app should provide the users with a platform to interact with the data to analyze the sensor data and initiate commands to control the equipment. The General Structure of the project constitutes the following components: • A wireless sensor network with a base station. • An Edge PC, that interfaces with the sensor network to collect the sensor data and sends it out to the cloud server. The system also interfaces with the sensor network to send out command signals to control the switches/ actuators. • A cloud that hosts a database and an API to collect and store information. • A web application hosted in the cloud to provide an interactive platform for users to analyze the data. The project was demonstrated in: • Lecture Hall (https://iac-lecture-hall.engr.iupui.edu/LectureHallFlask/). • Test Bed (https://iac-testbed.engr.iupui.edu/testbedflask/). • A company in Indiana. The above examples used sensors such as current sensors, temperature sensors, carbon dioxide sensors, and pressure sensors to set up the sensor network. The equipment was controlled using compactable switch nodes with the chosen sensor network protocol. The energy consumption details of each piece of equipment were measured over a few days. The data was validated, and the system worked as expected and helped the user to monitor, analyze and control the connected equipment remotely.

Principy zabezpečení bezdrátových standardů / Principles of the Wireless Standards Security

Vokál, Martin January 2007 (has links)
Computer networks are in the scope of the IEEE organization normalized by the 802 board which currently comprises six working groups for wireless communications. IEEE 802.11 for wireless local area networks, IEEE  802.15 for wireless personal area networks, IEEE 802.16 for wireless metropolitan area networks, IEEE 802.20 for mobile broadband wireless access, IEEE 802.21 for media independent handover and IEEE 802.22 for wireless regional area networks. This master's thesis focuses on a security analysis of particular standards, describes threats, vulnerabilities, current security measures and mutually compares wireless specifications from a security point of view. The conclusion is devoted to overall evaluation of the project, to its contributions, possible enhancements and continuation in the form of consequential studies.
