This paper deals with desgin and implementation of hardware and software for data acquisition device. Device is based on single board computer FoxBoard G20 which is placed on custom board which provide RS485 interface and short-term UPS. Device is runing Linux with device driver which enabling communication with Micropel PLCs across RS485 bus. Data are read from PLCs are saved to database and afterwards presented to user via web interface.

Steiger, V. Usage of ARM processors in heating control system. Diploma thesis. Brno: Mendel University, 2016. This thesis aims to simplify the process of controlling heating and cooling systems with standardised, widely accessible computers on purpose of integration into smart home systems. In theoretical part, heating systems available on the market are reviewed, mainly with focus on communication interfaces and protocols in use. Then the specifications of one of the most widely used protocol in heating systems communication OpenTherm, and one of the most widely used protocols in industrial computers communication RS485 Modbus are examined. Theoretical part also contains a description of integrated development environment and platform-specific development properties for STM32 ARM platform. In desing and Implementation is described RS485 Modbus OpenTherm converter firmware written in C language. Behaviour of the converter is then tested in practise.

The aim of this work is to design a safety module for promotional robot FEEC BUT robot, which is based on evaluation kit RDK-IDM-SBC. The security module allows authorized persons control different parts of the robot (monitors, computers and subsystems included in the robot).

The aim of this master’s thesis was the design RGB LED display with Ethernet interface. I created a display module, controlled by a microcontroller ATmega 2560-16AU. These modules can be connected via a serial RS485 standard. Ethernet connection is made via plug-in interface that uses the programmable module Rabbit RCM 3200. I documented a proposal. I tested designed device.

This master´s thesis deals with the design of measuring station used for the temperature and humidity measurement. There is a theoretical basical description of sensores for temperature and humidity measurement in the first part. Furthermore I deal with a theoretical design of measuring system, especially with types of materials and possibilities of communication between these parts. The main part of thesis is about communication on buses I2C,UART, SPI, RS485. There is a description of function procedure of particular integrated circuit, moduluses which are used in task in the next part of thesis.In the practical part I was engaged in a functional design of autonomous system for the temperature and ralative humidity measurement. Data could be presented by the computer after connection with the station. There is a description of testing the particular circuits and the full description of function particular blocks of system in the task. I have used the program called Eagle for schemes and printed wirings designing. The copy is placed on CD ready for next using. In the last part of thesis is a brief description of program algorithm "Meteostanice", which I have created for data presentation. There is an illustration of measuring results in these last part. The task is completely ready for the realization of autonomous system of weather station with its own memory.

This thesis presents the work of adding support for a communications protocol in a space application. The work is a part of KTHs MIST (MIniature STudent Satellite) project which aims at sending an experimental satellite into space. Each experiment on the satellite is designed as a subsystem. These subsystems need to be able to communicate with the main computer on the satellite in order to transfer the results of the experiments down to earth. In efforts prior to the current thesis, a special communications protocol has been specified to solve this problem. That protocol is called MSP (MIST Space Protocol). This paper describes the efforts to add support for MSP to two of the satellite’s experiments. These two experiments are called SiC in Space and Piezo-LEGS. However, since Piezo-LEGS is incompatible with the I2C bus in which MSP runs on top of, it must communicate through the SiC experiment. Which parts of the protocol that need to be supported by each experiment are defined. The result of the work is that the experiments can communicate with the main computer through the MSP protocol. / Denna kandidatuppsats beskriver arbetet med att implementera MSP protokollet för de två experimenten SiC och Piezo-LEGS. Syftet med MIST projektet är att skicka upp en experimentsatellit i omloppsbanan runt jorden. I satelliten finns ett antal experiment. De två experiment som arbetet ar fokuserat på är ”SiC in Space” och ”Piezo-LEGS”. SiC-experimentets syfte är att man ska göra mätningar på en kiselkarbid (SiC) transistor i rymdens vacuum. Syftet med Piezo-LEGS experimentet är att man vill mäta hur prestandan för en piezoelektrisk motor påverkas i rymden. Inom MIST-projektet har ett kommunikationsprotokoll som kallas MSP utvecklats för kommunikation mellan satellitens huvuddator och experimenten. I detta arbete har MSP protokollet implementerats för experimenten SiC och Piezo-LEGS Eftersom Piezo-LEGS experimentet är inte kompatibel med I2C bussen som används av MSP protokollet, utan istället använder sig utav ASCII-kommandon via RS-485, måste MSP kommandona översättas till ASCII-kommandon utav SiC.

The aim of this work is design of system for wireless data collection from energy meters. The work shows issues of smart metering and explains meters communication. There is designed and described concept of the system composed of RF modules connected to data concentrator. Designed RF module uses SoC radio CC430F5137 and it is connected to a data concentrator via RS485 bus. For the purposes of communication as well as firmware update, the communication protocol is designed. In the next part the work focuses on design and creation of RF module frmware, bootloader for RF module and software application for energy meter data processing.

The main objective of this work is to inform the reader of the communication protocols Modbus TCP and Modbus RTU and create an embedded device based on the microprocessor STM32 capable of conversion between Modbus RTU and Modbus TCP protocols. The device should be capable of simple first run configuration with simple user interface.

The concept proposal of the RFID security terminal is described in this Master Thesis. The RFID identification and its usage are analyzed at first. The description of the selected fitting circuits, communication bus as well as its parameters follows. The practical realization, proposed module design and designed printed circuit board is described afterwards. Several problems found during activation phase are analyzed in the chapter describing the practical module realization. The problem resolution is mentioned as well. The practical prove of the real module parameters and differences compared to the designed values are described at the end of this Master Thesis.

Main task of the Master Thesis is to introduce into sensor systems used in the field. On Advantech sensor system with use of ADAM 4000 modules is shown decentralized sensor system which comunicates over RS 485 and using master computer. Within Master Thesis was compiled measuring board and were assembled three programs which demonstrate possible use of different types of modules. Main development environment is used ADAMView. Each modules has different number and types of inputs and outputs. Using of sensor system saving measurement time, increasing measurement effeciency, relieves data processing and automatize measurement.
