Automation of software control systems
Sysel, Radek ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
The diploma thesis is about the design process of complex objects in automation and their rapid inclusion in the entire process technology. It shows the proces of creating a database model to generate into the SCADA application. The aim of the thesis is to show what all is needed to create, to produce a functional visualization model connected to the control system PLC. There is the analysis of the automated system change management, when it is processing technologies developed and we must do it based on customer feedback and revisions add new objects.

Secure and privacy-preserving data communication
Bernát, Michal ; Člupek, Vlastimil (referee) ; Malina, Lukáš (advisor)
This thesis discusses the possibility of ensuring the safety, integrity and authenticity of data communication with respect to user privacy. This thesis describes the fundamentals of smart grid networks with capabilities of existing forms of security to communications that have been chosen as a target for application deployment of group signatures to ensure the security, integrity and authenticity of data communications. It describes the concept of a zero-knowledge and cryptography primitives. Further, the basic principles are presented, the history of development, and various schemes are compared based on the construction and performance. The second part is given to the deployment and optimization of group signatures for computationally limited devices. Within the draft report were to be implemented in the Java language chosen scheme HLCCN, DP and BBS. They were then tested under various platforms which were measured and evaluated performance parameters of the schemes. The optimization of the work is focused on the times of signatures, which are critical to a smart grid system. Under the platforms are deployed pre-processed pairing optimization methods and other methods resulting from the deployment platform as JPBWrappera and native libraries to deliver more efficient times of sgnaiture. At the end of the thesis are evaluated achievements of optimization methods and the appropriateness of the deployment of smart grids.

Touch panel controlled PLC systems for HV device control
Vlk, Jáchym ; Vyskočil, Pavel (referee) ; Kubíček, Michal (advisor)
The master thesis describes communication of PLC and touchscreen with purpose of high voltage control. The general information and framework are included. The thesis describes part of IVEP corporation development. Due to the beginning of a long-term development it is premature to come into conclusions within this master thesis. The first chapter deals with PLC and other components. The second chapter consists of matters about high voltage devices. The following chapter describes the programme part. The fourth and concluding chapter deals with the realization of the communication itself. A brief evaluation with prospects for the future is included in the conclusion.
