Termisk energi som solfångare producerar kan lagras i Borehole Thermal Energy Storage, BTES, när efterfrågan är låg, för att sedan användas när efterfrågan är hög. Målet med detta examensarbete är att utveckla en skalbar systemarkitektur för styrning och monitorering av en BTES prototyp, där ringarna som borrhålen utgör är indelade i olika temperaturhierarkier. De ringar som ligger närmare centrum av borrhålen har högre temperaturhierarki än de som ligger längre ut. Driftinformation från systemet ska kunna följas på en webbplats och temperaturdata från systemet ska sparas undan för lagring. Datakommunikationen består av en One-Wire buss som innehåller temperatursensorer och ett CAN-buss system för datakommunikation mellan sensor/aktuator-noder och server-nod. Utifrån sensordata bestäms reglering av ventiler. Driftinformation lagras i en databas och från denna databas presenteras informationen på en hemsida. Hemsidan innehåller en överblick av brunnparken där temperaturen i varje brunn kan utläsas. Regleralgoritmen uppfyller den sökta temperaturhierarkin där de högsta temperaturerna ska vara i centrum av brunnparken. Prototypen fungerar som en utvecklingsplattform och demonstrerande prototyp. / Thermal energy produced from solar collectors can be stored in Borehole Thermal Energy Storage, BTES, when demand is low for later usage when demand is high. The aim of this thesis is to develop a scalable system architecture for control and monitoring of a BTES prototype.The BTES prototype consist of 13 boreholes configured in a hierarchically manner in two circles and one core. The core is of the highest priority. The operational information is displayed on a website and stored in a database.The data communication consist of two One-wire buses and one CAN bus. The temperature sensors are connected to the One-Wire buses. The CAN bus consist of sensor/actuator nodes and a server node. Based on sensor data, a control loop configures the actuators. Operational data is stored in a database and visually presented on a website. The website displays an overview of all the boreholes where all of the sensors data can be read. The control algorithm runs successfully according to its hierarchically priorities. The prototype works as a developement platform and a demonstrating prototype.

På försvarets materielverk (FMV) i Karlsborg utförs prover av militära vapensystem. Ofta när prov genomförs samlas också väderdata in för att veta om yttre faktorer kan påverka en träffbild. Insamling av väderdata är en manuell process som FMV önskar att automatisera. Målet är att skapa ett system med hjälp av en befintlig vädersensor som kan visa väderparametrar i realtid på en skärm samt spara dem vid rätt tillfälle på ett flyttbart media. Vid utveckling av system för insamling av väderdata ska det väljas ut lämplig hårdvara där även mjukvaran ska formas. Den teoretiska referensramen och litteraturstudierna utgjorde en bra grund för hela projektet genom att få en förståelse om alla de delar som måste tas hänsyn till. FMV har som krav att hårdvaran ska vara baserad på en integrerad krets. Det innebär kortfattat att det inte finns något operativsystem utan att det består endast av en källkod. Den befintliga vädersensorn som ska användas kommunicerar via seriell kommunikation. Det gjordes också ett val mellan två utvecklingsmodeller där en av dem senare ska användas som ett hjälpmedel för utvecklingsprocessen av hela systemet. Den utvecklingsmodell som var mest lämplig för projektet var V-modellen. Genom att använda V-modellen togs det fram en bra struktur för hur arbetet skulle läggas upp gällande planering, verkställande och testning. Med en detaljerad planering underlättade det verkställandet genom att det fanns en tydlig bild av vad som skulle göras. Den noga planeringen gjorde att fel och brister i systemet vid testerna var få. En nyckelfaktor för utvecklingsprocessen var också att ha ett bra samarbete med FMV:s personal vilket gjorde att utvecklingen följde deras vision om systemet. När utvecklingsprocessen och arbetet med V-modellen var genomfört var också ett system för insamling av väderdata framtaget och godkänt av FMV. Systemet generar en minskad hantering av data eftersom det utför det arbete som tidigare har varit manuellt. Det generar också stabilare mätvärden eftersom tidpunkten för loggningen blir mer exakt än tidigare.

Context. Internet of Things (IoT) is an extension of the Internet, which now includes physical objects of the real world. The main purpose of Internet of Things is to increase a quality of people’s daily life. A smart home is one of the promising areas in the Internet of Things which increases rapidly. It allows users to control their home devices anytime from any location in the world using Internet connectivity and automate their work based on the physical environment conditions and user preferences. The main issues in deploying the architecture of IoT are the security of the communication between constrained low-power devices in the home network and device performance. Battery lifetime is a key QoS parameter of a battery-powered IoT device which limits the level of security and affects the performance of the communication. These issues have been deepened with the spread of cheap and easy to use microcontrollers which are used by electronic enthusiasts to build their own home automation projects. Objectives. In this study, we investigated wireless communication technologies used in low-power and low-bandwidth home area networks to determine which of them are most suitable for smart home applications. We also investigated the correlation between security, power consumption of constrained IoT device, and performance of wireless communication based on a model of a home automation system with a sensor node. Sensor node was implemented using Arduino Nano microcontroller and RF 433 MHz wireless communication module. Methods. To achieve the stated objectives of this research following methods were chosen: literature review to define common applications and communication technologies used in a smart home scenario and their requirements, comparison of wireless communication technologies in smart home, study of Arduino microcontroller technology, design and simulation of a part of  home automation project based on Arduino, experimental measurements  of execution time and power consumption of Arduino microcontroller with RF 433 MHz wireless module when transmitting data with different levels of security, and analysis of experimental results. Results. In this research, we presented a detailed comparison of ZigBee, WiFi, Bluetooth, Z-Wave, and ANT communication technologies used in a smart home in terms of the main characteristics. Furthermore, we considered performance, power consumption, and security. A model of a home automation system with a sensor node based on Arduino Nano was described with sleep management and performance evaluation. The results show that the battery lifetime of Arduino in a battery-powered sensor node scenario is determined by the communication speed, sleep management, and affected by encryption. Conclusions. The advanced communication strategy can be used to minimize the power consumption of the device and increase the efficiency of the communication. In that case, our security measures will reduce the productivity and lifetime of the sensor node not significantly. It’s also possible to use symmetric encryption with smaller block size.

The house in which the family live, should be built for the specific lifestyle residents and respond intelligently to their current and changing needs. Nowadays there are some new buildings that have such requirements partially resolved. The proposed project is based on the situation of families living in older buildings that no longer complies with their needs. Therefore they are considering home reconstruction to transform house into so-called "smart" house or apartment. The project deals with the functioning of modern living that reflects the lifestyle and how to be a house or flat is used. It takes into account the location of individual system components (control and regulation elements, controls, cameras, sensors, audio-visual equipment, etc.), and their interconnection to the selected specific component types that are in keeping with the style and interior design. The work is based on the description of the ideal smart home functionality to create smart design solutions of selected house based on currently available technologies. Detailed design is developed using available technology to control home appliances.

En 4x4x4 kub konstrueras av RGB LED's med integrerad drivrutin och via en Arduino styrs den av musiken som spelas. Arduinon får musiken som input och med hjälp av fouriertransform delas signalen upp i 128 logaritmiskt uppdelade bins. Efter många olika teorier om hur bas, volym och känsla skulle kunna bestämmas i Arduinon bestämdes slutligen att de skulle bero av olika frekvensintervall; basen i 50-250 Hz, volymen i 500-2000 Hz och känslan i 2000-4000 Hz. Basen förflyttar mönstret framåt, volymen bestämmer ljusintensiteten (mellan 50% - 100% av max) och känslan avgör vilket av 6 mönster som aktiveras.

A Stewart Platform robot was designed, constructed, and programmed for use in Cal Poly’s ME 423 Robotics: Fundamentals and Applications laboratory section. A Stewart Platform is a parallel manipulator robot with six prismatic joints that has six degrees of freedom, able to be defined in both position and orientation. Its purpose is to supplement parallel robot material covered in lecture. Learning objectives include applying and verifying the Stewart Platform inverse kinematics and investigating the Stewart Platform’s operation, range of motion, and limitations. The Stewart Platform geometry and inverse kinematics were modeled and animated using MATLAB. The platform was then built using linear actuators, magnetic spherical bearings, and acrylic plates. Control of the Stewart Platform is achieved using an Arduino Due and a custom HexaMoto shield. Users interact with the system using a GUI created with MATLAB’s App Designer.
