This master’s thesis extends the teaching possibilities of the course “Building automation” in two areas. The first area is the visualization of KNX educational panel, which is made through iRidium software package in several variants. The second area is the design and manufacture of the educational switch panel with different types of switches, in which students can simply try wiring, which are commonly used mainly in civil engineering. Part of the second area is the creation of several teaching tasks.

Hur mycket värme strålar in genom fönster? Det beror på vilket håll de är vända mot och deras storlek. I den här rapporten jämförs två metoder för att hindra en temperaturhöjning. Den ena metoden är med luftvärmepump som jämförs kostnadsmässigt med den andra metoden som är automatiska persienner. Beräkningen av vad det kostar att kyla bort värmen med värmepump sker i MATLAB. Styrningen av persiennerna sker i det här fallet med hjälp av KNX. Kommunikationen sker via en buss. För att programmera styrningen används ETS5. Beräkningarna grundas på antagen att byggnaden har 8 m² fönster i sydlig riktning, 5 m² i östlig riktning och 4 m² i västlig riktning. Den tillförda värmen över hela året antas vara 10 000 kWh. Beräkningen tar inte hänsyn till yttertemperatur och är därför lite missvisande. Mätdata för antal soltimmar hämtas från SMHI för att beräkna solinstrålningen genom alla fönster. Med hjälp av denna information beräknas kostnaden att kyla bort solinstrålningen till 460 kr per år. Inköpspriset för luftvärmepumpen är 20 350 kronor. Priset för en persienn är 10 000 kronor. Författaren rekommenderar luftvärmepumpen för nedkylning av byggnaden i detta fall. / How much heat radiates in through windows? It depends on their direction and the size of them. Two methods to prevent a temperature increase are compared in this report. The first method is by removing the heat with a heat pump, which is compared to the second method that involves automatic blinds. The cost to run the heat pump to remove the heat is calculated in MATLAB. The control of the blinds in this case is with KNX. The communication is done through a bus. ETS5 was used to program the blinds. The calculations assume that the size of the southern windows are 8 m², the east-facing windows are 5 m², and the west-facing windows are 4 m². The added heat is assumed to be 10 000 kWh throughout the year. The calculations does not take outside temperature into account. Data for the amount of sunshine is taken from SMHI. With the help of this information the cost of cooling the radiated heat is calculated to 460 swedish crowns per year. The cost of buying the heat pump is 20 350 swedish crowns. One blind costs 10 000 swedish crowns to buy. The author recommends the heat pump to cool the building in this case.

The master thesis discusses about the relation between high-speed networks and intelligent system installation features and possibilities of this mutual interaction. Furthermore principles of KNX bus tunneling through IP networks are theoretically analyzed (KNXnet/IP). Practical use of implements KNXnet/IP shows real elements on the test panel. The control is realized by KNX@Home in the Ubuntu environment. Simulation of the real state tunneling KNX bus represent model in Opnet Modeler, which shows how the delays may change due to network load.

Three different system block diagrams, software algorithm and its implementation methods were given and analyzed. A model of the user interface was created. An investigation was made. The goal of it is to evaluate the main user interface parameter – activation time which makes a better usability of the whole system.

Master thesis on topic Design of intelligent data distribution network is focused on the design of KNX bus system. The theoretical part is focused on problematic of KNX technology and on the rules, regulations and forms which must correct project documentation contain. The practical part is focused on creation of complete design of project documentation KNX bus system. In this thesis is basically shown how project documentation should look like.

The thesis is focused on bus systems and their control by GUI. Basic energy management principles and the mostly known bus systems are analysed in the first – theoretical part of the paper. The theoretical part is then focused on software tool ETS 4, which is used for activation of system installation KNX. Software tool SmartServer, which is used for communication between bus system KNX and web interface, is described at the end of the first theoretical part. Two laboratory boards assembled of KNX and DALI parts were constructed in the second – practical part. Three laboratory tasks, which are prepared so they are related to theoretical description in previous part, were submitted in next step. Aim of the first task is to introduce basics of the board and PriOn interface. The second task is focused on DALI components and temperature control with PriOn regulating device. Creating of basic visualization and controlling of the board with SmartServer is described in the last task.

Cette thèse aborde la performance du protocole KNX-RF utilisé dans les applications domotiques en termes de robustesse Radio Fréquences dans un environnement multi-protocoles potentiellement sujet aux interférences. Dans ces travaux, le but est d’évaluer les problématiques d’interférences rencontrées par KNX-RF en utilisant des modèles de simulation qui permettraient d’augmenter à sa fiabilité radio. Ainsi, un premier modèle a été développé sur MATLAB/Simulink et a permis de connaître les performances et les limitations de ce protocole au niveau de la couche physique dans un scénario d’interférence se produisant à l’intérieur d’une box/gateway domotique multi-protocoles. Ces simulations ont été complétées par des essais expérimentaux sur le terrain qui ont permis de vérifier les résultats obtenus. Un deuxième modèle a été développé pour évaluer les mécanismes de la couche MAC, cette fois-ci, grâce au simulateur OMNet++/MiXiM. Ce modèle reprend tous les mécanismes d’accès au canal et d’agilité en fréquence spécifiés par la norme KNX. Un scénario de collisions de trames a été simulé et plusieurs propositions d’améliorations sont discutées dans ce manuscrit. Les modèles développés permettent d’analyser et de prédire en avance de phase le comportement de KNX-RF dans un environnement radio contraignant. / This thesis addresses the performance of the KNX-RF protocol used for home automation applications in terms of radiofrequency robustness in a multi-protocol environment that is potentially subject to interferences. In this work, the aim is to assess the interference problems encountered by KNX-RF using simulation models that would increase its RF reliability. Thus, a first model was developed on MATLAB / Simulink and allowed to investigate the performance and limitations of this protocol at its physical layer in an interference scenario occurring inside a multiprotocol home and building automation box/gateway. These simulations were followed by field experimental tests in an indoor environment (house) to verify the results. A second model was developed to evaluate the MAC layer mechanisms of KNX-RF through the discrete event simulator OMNeT ++/Mixim. This model includes all the mechanisms of channel access and frequency agility specified by KNX-RF standard. A frame collision scenario was simulated and several improvement proposals are discussed in this manuscript. The developed models can be used to analyze and predict in advance phase the behavior of KNX-RF in a radio-constrained environment.

Les besoins de nouveaux services dans les rames ferroviaires ( le comptage, l’efficience énergétique, le confort et la sécurité des passagers etc.), risquent de saturer à terme les systèmes de communication filaires mis en place il y a une vingtaine d’années. Les réseaux de capteurs sans fil, par leurs avantages (déploiement facile, capacité à s’adapter à plusieurs types d’environnements, faible consommation d’énergie), ouvrent de nombreuses perspectives pour les systèmes de gestion énergétique. Le but de ce travail de thèse est d’étudier et mettre en oeuvre un réseau de capteurs sans fil à l’intérieur des trains pour l’efficience énergétique. Ainsi, quelques protocoles de communication dédiés à la gestion énergétique ont été présentés puis une étude comparative des différents réseaux de communication sans fil réalisée. Cette étude comparative a permis de faire le choix du réseau ZigBee comme étant le plus adéquat pour la plateforme. L’architecture hybride proposée permet l’utilisation du réseau IP existant comme colonne vertébrale de l’ensemble des réseaux ZigBee. Afin de tenir compte de l’effet de l’environnement ferroviaire dans la planification et le déploiement du réseau, une étude du canal de propagation, basée sur des mesures réalisées dans un métro et un wagon de RER a été menée. L’impact de la coexistence entre le ZigBee et le WiFi et de la présence humaine sur la communication du réseau sans fil a été démontré. Le prototype d’une plateforme basée sur le réseau ZigBee allant de la collecte des données à l’affichage des informations a été réalisé et testé. / The need of new services in railway trains (services for metering, energy efficiency, the comfort and safety of users etc.) may eventually saturate the wired communication systems installed since twenty years ago years. The several advantages of wireless sensor networks (easy deployment, ability to adapt on different environments and low energy consumption) offer many possibilities for energy management systems. The aim of this thesis is to study and implement a wireless network sensors inside trains for energy efficiency. Thus, some communication protocols dedicated to energy management were presented and then a comparative study of the various wireless communication networks carried out. This comparative study shows that the ZigBee network is the most suitable for the platform. The proposed hybrid architecture allows the use of the existing IP network as the backbone of all ZigBee networks. In order to take into account the effect of the railway environment in the planning and deployment of the network, a study of the propagation channel was carried out, based on measurements realized in a subway and a RER car. The impact of the coexistence between ZigBee and WiFi and of the human presence on wireless communication have been demonstrated. The prototype of a platform based on the ZigBee network, allows data collection, informations traitement and monitoring, was carried out.
