GSM brána pro PLC systémy / GSM gate for PLC systems

Kadaňka, Karel January 2019 (has links)
The master´s thesis describes the initial design of communication module for industrial automation purposes which can transmit short status messages via the GSM network informing about the status of the connected device to a predefined telephone number. In the first part, the communication protocols are describe and a market survey is carried out. Then follows the evaluation of the market survey and the justification of construction of the device. The following chapters are devoted to the description of the device being developed, its individual components and program description and testing prototype.

Samoorganizující se sítě typu MESH / Self-organizing MESH wireless networks

Němec, Petr January 2009 (has links)
This master thesis deals with self organized Mesh network. It describes routing and particular routing protocols, which are used in these networks. The thesis deals with Mesh network QoS assurance. Analysis and theoretical background of Mesh networks, routing and router protocols are included in the first chapter. Basic models of assuring Quality of Service are also described. Those are Best Effort, IntServ and DiffServ. Second chapter describes the devices used in the specific Mesh network topology - Trospos 5210 MetroMesh router produced by Motorola Canopy. Basic settings and properties required to establish a Mesh network are described. Next part of the thesis is the design implementation, which involves creation and configuration of the Mesh Network. Network configuration consisting of two Gateway points and afterwards behaviors of the network in a steady state versus one gate failure are compared. Furthermore, implementation of QoS according to components that support two types of QoS assurance regarding type of bandwidth reservation and defined traffic classes. In conclusion, the thesis describes measurement methods of QoS parameters for chosen applications, evaluation and comparison of measurement results for both types of Quality of Service assurance.

Možnosti přenosu signalizace SS7 přes IP síť s využitím ústředny YATE / The possibilities of SS7 signalling transport over IP network using YATE switch

Al-Anqari, Mhannad January 2013 (has links)
This study examines the use of SS7 signaling system over IP networks by using the open source PBX YATE. At first it starts with describing the SS7 followed by an explanation of the function of each of its levels and the messages that are used within the SS7 network. The study then sheds some light on the ways of using SS7 inside IP network with the use of some protocols. It also discusses the architecture of YATE and its files, and how it is installed in Linux operating system. Finally, it describes the important files for delivering this task. The study was commenced by using two virtual machines that have two different open source PBX's which are YATE and Asterisk, and after acquiring some results by establishing communication between them via the means of SIP trunk, furthermore the study was extended to the laboratory in order to test it over real servers that have TDM cards, in order to apply the study by the means of SS7 protocols, SIGTRAN, MGCP gateway and SIP-T. The experiments have almost delivered successful communications after conducting a configuration for the files on multiple sides.

Periferie na Foundation Fieldbus / Foundation Fieldbus peripheries

Ferjančič, Michal January 2013 (has links)
Master’s thesis deals be occupied with the transmission of process data with peripheries to control devices. Data transmission with performs through two types of industrial networks. Use with these two Foundation Fieldbus and EtherNet / IP. In work is shows method conversion through gateway between the two networks. Here there is adduced method to connected and configure devices on the networks and also their implementation. Part of this work is also creating a visualization of these peripherals and the gateway. The work is also presents possible use for laboratory task to practice.

Brána pro překlad signalizačních zpráv pro videokonference / Signalling gateway for videoconferencing

Seifert, David January 2013 (has links)
Generally, the term gateway (gateway) in computer networks holds a node that connects two networks with different protocols. This thesis deals with the translation between two protocols, SIP protocol and WebSocket. This translation is the work first described theoretically and then work deals with the way this translation solutions using tools available on the Internet.

Pozorování amplitudových a fázových předmětů přes rozptylující prostředí pomocí holografického mikroskopu s kontrolovatelnou koherencí / Amplitude and phase objects observation through scattering media by means of coherence-controlled holographic microscope

Effenberger, Adam January 2015 (has links)
This diploma thesis deals with phase and amplitude objects observation through scattering media by means of a coherence-controlled holographic microscope (CCHM). A brief history of development and construction of the microscope, its advantages compared to the classical light microscopy and hologram processing are described. Quantitative phase imaging through scattering media by means of ballistic as well as diffuse light is verificated in the experimental part. A comparison of an image obtained through a scattering layer by means of CCHM and a classical microscopy in the light field is demonstrated.

Autonomní správa inteligentní domácnosti / Autonomous Management of Intelligent Home

Punčochářová, Pavlína January 2016 (has links)
Currently, the topic of smart home is not new and there are many solutions for this problem on a market. Emphasis is placed on miniaturization of the individual elements of an intelligent system and control logic of the system as a whole. This is associated with requirement for ensuring management capabilities of the system in case of failure of the connection between some of the functional elements and the control member.  This work deals with design and implementation of modifications in intelligent home gateway in an existing BeeeOn project to ensure its autonomy even in case of loss of internet connection. The problem of loss of ability to manage the household is solved by adding the possibility to establish direct communication with the gateway and the introduce automation ability into gates to control household without the participation of the controlling member. This extension brings autonomy into the system and allows user to have the household under control even in case of loss of internet connection. It leads to increase system security and quality of service in general.

Možnosti uplatnění regionální značky na území MAS Brána Vysočiny

Dohnálková, Kristýna January 2019 (has links)
Diploma thesis focuses on the possibilities of applying the regional brand in the area of LAG Brána Vysočiny. Theoretical part discusses relevant terms, such as endogenous development, local product, regional brand, local action group and territorial marketing. The region of mentioned LAG is introduced in the next part of thesis, primarily are researched the conditions for implementing regional brand. Main part of thesis deals with the most significant steps which should be considered while implementing new regional brand to the region. Personal interviews with regional brand coordinators were used as an information source for this part. Main part also includes suggestions on how to build regional brand in the circumstances of LAG Brána Vysočiny. It is also discussed the importance of regional brand as a tool of supporting tourism in the region. Thesis further analyses whether is possible to build regional brand under control of Association of Regional Brands or build it independently. Final chapter summarizes acquired findings, advantages and disadvantages of both implementing types are identified as well. Results showed that both implementing types are working on similar foundations but have several differences which can be crucial when deciding how to implement regional brand in the region of LAG.

Doklady kontinentálního zalednění v reliéfu Moravské brány / Geomorphological evidence of the Scandinavian glaciation in the Moravian Gate

Pavurová, Zuzana January 2010 (has links)
Geomorphological evidence of the Scandinavian glaciation in the Moravian Gate Abstract This thesis is aimed at area in the Moravian Gate which was covered by continental ice sheets during the Quaternary. The goal of this thesis is to analyze results of work of Tyrá ček (2006). Main parts of this thesis are: current views on the extent of glaciated area, definition ice-marginal landforms, methods my fieldwork, results and discussion. Maps and graphs were created as a part of this thesis. Data was processed using MapInfo Professional 7.0 SCP software, ArcGIS 9 software a Microsoft Office Excel 2003.
