The aim of my master’s thesis is a system for control of the light intensity. It is electronic equipment which controls the intensity of the light circuits based on settings and input signals. This equipment could work on single-phase systems or multiphase systems. The equipment is controlled by the signal DMX-512 which is a standard for the control of lighting technologies. The set up of this equipment is based on a personal computer or in a limited form by a small connected display.

Rapporten beskriver arbetet med att modernisera en testutrustning för ett robotsystem. Den nya testutrustningen skulle moderniseras till att använda USB-gränssnitt istället för RS232-gränssnitt för kommunikation mellan dator och den övriga hårdvaran. Arbetet börjar med kravspecifikation och slutar med en fungerande produkt. I det innefattas en kortare förklaring av USB-gränssnittet och dess skillnader från RS232-gränssnittet, en utredning för att finna den bästa lösningen för att förverkliga USB-kommunikationen med utrustningen och konstruktion av elektronik för att styra signaler och spänningsmatningar till robotsystemet. / This report describes the work to modernize a test equipmentt for a missile system. The new test equipment would be upgraded to use a USB interfaces instead of RS232 interface for communication between the computer and the rest of the hardware. The work begins with the specification and ends with a working product. In that included a brief explanation of the USB interface and its differences from the RS232 interface, an investigation to find the best solution for implementing USB communication with the equipment and construction of electronics to control signals and power supplies to the missile system.

This diploma thesis deals with the design and implementation of a computer-controlled device for testing gas boiler control units, especially in the development phase. The reason for creating a test facility is the inadequacy of older test systems and the automation of existing testing. The test device in development consists of individual different cards. Each of the cards inserted into the motherboard performs its function in the system. Each of the cards has a special functionality which simulates the real conditions of the developed product. The basis of most cards is a microcontroller with a Cortex-M core, which communicates with the connected computer using the MODBUS protocol on the RS-485 communication interface. All cards on the bus are connected in parallel and behaves as a SLAVE, while the computer behaves as a MASTER and requests data or sends commands to the cards. The cards represent status switches (switching sensors), resistance and analog temperature sensors, PWM inputs and outputs (for simulation of feedback pumps or flow meters with pulse output). The cards also include a flame simulator, which reliably simulates the electrical properties of the flame and at the same time acts as a fan simulator. The input of the control unit is taken care of by the input card, which is intended for digital detection of the voltage presence in the range of 5 to 230 V DC and AC. Simultaneously, a card for connecting the power supply at zero voltage and disconnecting at zero current is created to supply the tested device with alternating voltage. A schematic diagram was designed or simulated for each card, then the function was verified and on this basis the whole card was created, including the microcontroller firmware. The most suitable solution and function of each card is carefully described and evaluated. All the requirements of the assignment within the work were met and the whole test equipment was manufactured and verified in four versions. In the future, the device is ready for the implementation of an automatic flame simulator and other improvements of individual module cards.

This work deals with analysis methods continuous measuring systems for measurement standing wave ratio and high frequency power. Reflectometr, provision measuring standing wawe ratio, works in range frequence VHF (145 MHz, 443 MHz), for this width working frequence is used construction reflectometer with directive lead. Measurer HF power works into range 1kW. Further is in work go through problems communications bus for transmission data from unit monitor SWR a HF power into score modulus. With regard to high frequency interference is choice serial communication RS-485 , which is immune against disturbance. Further is designed evaluation unit MASTER, unit SLAVE and modules for measurement power and SWR. In finish is build up the firmware for units.

This thesis deals with the measurement of physical quantities in building using decentralized system for data collecting. The system consists of Raspberry Pi as a master device of the system. There are three branches connected to this master device. Each branch consists of up to 32 modules for data-concentration from sensors of physical quantities. The Raspberry Pi has implemented web interface for displaying measured values and system administration.

The theme of this thesis is the design of peripheral devices of a smart home SmartFlat and the design of communication interface for this system. Designed units are the humidity and temperature measuring unit, the unit of security and the smart socket unit for remote control, power measurement and power control. All units are designed for wired communicaton and also for wireless communication with control unit.

This paper deals with the hardware and software design of the data acquisition distributed system with large amount of connected sensors. The intended application of this work is measuring some physical quantities in the building constructions. The designed system is hierarchically divided into the three levels. On the highest level there is a single-board computer Raspberry Pi which is used as a master on RS-485 bus. There can be up to 32 slave devices on the bus while each of them collects data from the sensors connected to 4-channel I2C bus. At the same time the Raspberry Pi is used as a web server, providing the user interface of the system.

In control technique there is evident highly expressive trend of shifting from efficient central managing systems towards smaller systems which are distributed on technology and which are connected by communication bus. There is no need to link all signals to central management system, operation is then distributed and realized directly in individual parts of technology. That’s why these systems are called distributive managing systems. Distributive managing systems are widely used not only in industrial applications but also in buildings, cars, etc..

This thesis deals with design and implementation of a versatile control unit, which is primarily designed for control of solar collectors. It describes the various stages of design. First, the system of solar collectors is introduced. Its input-output parts are analyzed and the requirements are determined for the control unit. The characteristics of temperature sensors are examined, the work deals with continuous variable speed circulators. The following part is dedicated to hardware and software implementation of the objectives of the work. The boards were designed in Eagle design environment, the firmware was written in C programming language. In conclusion, the evaluation of the results of the proposed system and possible ways of its further development are discussed. The versatile control unit can be deployed in practice realistically.
