Remote control of remote communication board of mobile robot
Jílek, Tomáš ; Žalud, Luděk (referee) ; Burian, František (advisor)
The thesis discusses the possible ways of remote management of devices running Mikrotik RouterOS and choosing appropriate variant for implementation of automated remote management of the device, which is part of a mobile robot. Due to the limited capabilities of embedded system, from which it is necessary to perform automated remote management of device with this operating system, it was not possible to use standardized protocols for this purpose. A substantial part of this work therefore deals with analysis and detailed documentation of proprietary protocols implemented in the MikroTik RouterOS operating system, which are suitable for implementation in an embedded system, from which it is necessary to perform automated remote management. The conclusion describes the principle of the proposed and realized implementation of proprietary protocols in C language. The described implementation is part of the library, which provides automated remote management using these protocols.

Server and client management hosting services using Qt4 framework and Linux
Matas, Jakub ; Stančík, Peter (referee) ; Matocha, Tomáš (advisor)
This thesis deals with the design and the implementation of a client/server application for the administration of hosting services. Other solutions of hosting services administration are listed as well and they are contrasted and compared with the assigned solution. A description of the particular hosting services and their setting for the Ubuntu Linux distribution are provided. A communication protocol and a data store serving to save all the client accounts and servers were designed. Basic principles of working with C++ framework Qt and its usage for the implementation of both the server and the client application are demonstrated. The basic settings of the server application enabling it to be launched on the server as a service are mentioned as well. In the last part a description is stated of working with the client applications and administration of the client accounts.

Remote maintenance of the microcontroller systems
Vágner, Martin ; Hynčica, Ondřej (referee) ; Kučera, Pavel (advisor)
This thesis deals with methods of remote maintenance of microcontroller systems based on Atmel AVR family over the Ethernet interface and TCP/IP protocols. To create communication through TCP/IP, an embedded server NE-4100T is used. At the beginning, key features of the server and methods of handling with content of a program memory are discussed. The final solution is based on the bootloader method. It includes bootloader firmware and user program for PC. The hardware part covers design of interconnection electronics, DC-DC step down converter, real time clock and printed circuit board. The remote maintenance of program memory has been sucessfully solved, but the embedded server NE-4100T produces a problem with an auhentification without a sufficient solution.

Controling the dust exhaust of smeltery for recyclation of aluminum waste
Jakubský, Ondřej ; Nadrchal, Zdeněk (referee) ; Trnka, Vladislav (advisor)
The work deals with controlling and visualizing technology of dust exhaust of smeltery for recyclation of aluminum waste. In the first part of the work are analyzed the different ways of automatic control. Based on the analysis is proposed control system configuration, algorithm of control, communication interfaces and sensors of alarm, measurement and regulation. The second part deals with visualization and remote administration of control system. On the basis of selection for the visualization software is designed and implemented a system that provides visualization of technology, the archiving of measured operating values, events and errors.

Building and using a smaller business computer network
Černý, Jan ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The aim of this bachelor's dissertation is to characterize and specify problems of Local Area Networks. Its first part summarizes the essential theoretical basis that is necessary for comprehension and understanding of the main part of the dissertation which describes a particular case of cooperation with an unnamed transnational company. The theoretical introduction gives the description of the defining characteristics and the classification of computer networks, then it describes the reference model ISO/OSI, and the characteristics of some active pieces of equipment, such as a HUB, SWITCH or ROUTER. In the main part of the dissertation, there is a detailed description of the restructuring of IT and the network infrastructure of a Czech branch office of the transnational company. The task given by the company was to restructure their IT and network infrastructure, to conceive a plan, realize the solutions, and, in case of necessity, to do and complete the installation or configuration. The objectives were fulfilled according to the demands of the head of the Czech office, as well as according to the instructions of the IT department of the company headquarters in Switzerland. At the beginning of the main part of the dissertation there is a description of the initial stage of the IT infrastructure of the Czech branch office before the demand for its development was asked for. Then all the steps of dealing with the tasks are described in detail and the new conditions of the upgraded IT and network infrastructure are described and assessed. The final part of the dissertation is a mix of theoretical and practical block describing the Cisco operating system. There is a short theoretical characteristic and several examples of the possible configuration of swithes and routers in a simulated realization of possible solutions in local area network of a smaller company with the help of the application called Packet Tracer. The last example simulation is aimed at a virtual LAN (VLAN) configuration with the use of two switches and a virtual "trunk" ant its security.
