The diploma thesis deals with the implementation of own design of an electronic security system with the possibility of extension with the elements of home automation. The control panel is built using the Raspberry Pi3 B+ with a touch screen that communicates with the sensors using Bluetooth Low Energy technology.

The aim of this thesis is to inform readers about the basic principle of electronics for which the service module for the automatic sanitary technique will be designed, as well as design and describe the most important parts of the module theoretically. Likewise, the thesis deals with the most common mistakes in the design of printed circuits boards with respect to the resistance of the resulting device against interference. The implementation itself includes both module design and a communication algorithm for connecting multiple service modules and their remote control using the Raspberry Pi minicomputer. The thesis also contains a design of algorithm for verification of data transmission by the transmission system.

The goal of this master thesis was create suitable and easy to use software, which can help workers with maintaining of elevator. For this purpose it was necessary to study communication interface and protocol of control unit borrowed from the company Výťahy ZEVA s. r. o. There was necessary to find suitable device for communication between control unit and server. Server is used for store and visualize actual data of elevator system. Server can set the parameters of the elevator remotely and demand actual configuration of elevator. User can watch historical data from server. The users use server after authentication with different competency. Users with an appropriate competency can set the notifications in the system, which can warn their in case of problem with elevator and reduce the reaction time and time to resolution of the problem.

This thesis adresses designing a device that detects lane departure of a vehicle via a video feed from a camera module. This device is intended to be attached onto the windshield of the vehicle. The initial part of the thesis will cover the current methods of lane departure detection through a video feed. In the following part the selection of suitable hardware, specifically the latest model of a Raspberry Pi, has been made. Afterwards a suitable container for the aforementioned hardware has been designed and created using a 3D printer. Subsequently an appropriate LDWS algorithm is chosen and designed. In the next part, the range and parameters of a testing database through which the proper functionality of the device will be tested on are chosen. The final part of the thesis contains evaluation of the success rate of detection via the acquired database.

This diploma thesis deals with the research of existing solutions of electronic information systems. The purpose of this survey is to inspire what is offered to users of these professional systems, or what users expect from these systems. Based on the acquired knowledge, the thesis also deals with the design of its own system, which can serve as another alternative to professional solutions of companies on the market, in the sense of the concept of solution of the given task. After the design of the system, the thesis deals chronologically with the selected "tools" used for the actual implementation of the assigned task Electronic Information Boards. Both hardware and software parts of the task, which form the majority of this thesis. At the end of the work are presented practical results.

This work deals with the collection of data from analog sensors, their storage and display using the Raspberry Pi microcomputer. In more detail it deals with selecting the appropriate analog-to-digital converter, selecting the appropriate storage and database server, web server and application to display the measured data.

This work deals with connecting remote devices measure data of various types from physical quantities such as a temperature, a humidity to data displaying CPU or memory usage of the system to the user. The system uses Blockly to controlling logic and dependencies between devices. In the work is used lots of technologies for examples: MQTT, Websockets, GSM, Lightweight Mesh and others. The system is based on microservice which named is Flask. Flask service is an application interface for HTTP services of Python programming language. This can provide measured data by graphs and predefined components for viewing data. For controlling system was used single-board computer Raspberry Pi with a multitouch 7-inch display.

Master thesis deals with concept and realization of wireless measuring system, powered by battery. The system consists of two main parts. First part, the node, is designed for the lowest possible power consumption. This is achieved mainly by usage of microcontroller from the STM32 family. Gathered information is transfered via RFM69 module. Second part, the gateway, is powered by Linux operating system on Raspberry Pi. Data from the gateway proxy are propagated through MQTT into Home Assistant, which interprets the results.

The thesis is about industrial automatic CIP protocol, which belongs to SCADA systems. The first part is focused on basic principles of CIP protocol and on analysis of two protocols (EtherNET/IP and DeviceNet), which are based on CIP protocol. The second part deals with designing scenarios for a simulation. The simulation of one-way communication, two-way communication with help of reads from the console and two-way real time communication between Raspberries PI 3B+. The third part deals with a realization of the simulation, a start-up and a function of predefined scenarios and graphic interface. The fourth part deals with analysis network communication in situations, which occur during a protocol EtherNet/IP simulation.

Thesis is focused on the digital measurement of power consumption and distribution the measured results to the remote monitoring center over computer network. The appli- cation is designed for monitoring of active elements computers network.
