IntroductionWhat means Domotics?a technological science which studies all devices in the house or the building, facilitating the work and increasing the comfort of peoples,is focused on the integration of all automations within the house,

.andcreates an ideal environment for the human life the DREAM HOUSE !

Functionalities implemented into a Dream HouseHealth care andmonitoring

What a current automate system is doing in house?A home automation system automates the whole house, triggering events and routines involving light fixtures, security components and the heating/cooling system based on the time of day, temperature or any other condition that you select Recognize stages and react adequate (specific) at these

Dream House means integration and intelligenceINTEGRATION (i)Assures specialized control systems in house, such as: HVAC;White good elements;Security and Access system; Audio-video systems; Motorized systems;Monitoring systems;Communication systems.

Integration(1)Fusion of different kinds of information (that means to take into account the majority or all of them at the reaction of smart objects)Better coordinate the objects integrated in order to:Saving energy or row materials Increase functionality of smart elements Reducing the reaction timeSensing the context and adapt the own reactionAdapting their response at the specificity of human operator

Intelligence of elements (2)This feature consist in the capacity of elements to offer:An adequate response at stimuli or events assuring a correlation of the response with a large factors number. The result is function from the current stage of element and the interactions this and his neighborhoods)Dynamic response (is changed during the response action)Complex response ( the response is formed by a set of actions triggered by a specific event)

INTEGRATION (ii)HVAC systemsAdapt better the parameters of systems to each otherAdjust dynamically those parameters in a synergetic way making life more pleasant Save energy by optimizing the functioning regimes of HVAC

INTEGRATION (iii):Lighting systemOptimize the light adequate with the destination of room or place illuminated Switch automatically the bulbs by sensing the human presence in the roomUse a optimal illumination of rooms by combining the natural with artificial illuminationAccept a large variety of switching elements that can be placed with minimum restrictions on the walls of the room (see capa-link solutions)

INTEGRATION (iv):Security and Access systemSeeing and talking to the person at the door or gate before opening it Electronic door locks can provide security as well as the ability to lock the building or allow emergency access with one command Accept a variety of configurations that allow to calculate a large kinds of logical functions between the sensing signals and the actuators controlled by system

INTEGRATION (v):Audio video systemsThe media room where the family can spend time together in a less formal entertainment setting. Speech interface will provide the ability to control systems without having to press buttons or touch screens. Provide a high conectivity with the other systems existing in house

INTEGRATION (vi)Other systems:Motorized door and windows and blind windows openers allow ventilation and access Motorized window treatments can automatically open and close to allow sunlight and privacy as needed. Remote vehicle starters provide a warm vehicle in the colder climates, and can open doors and ramps if the vehicle is so equipped.

Design principles related to the sub-systems of the Dream HouseStructural design means the representation (the model) of all elements included in house automations and the links between one each otherFunctional designmeans the functional mapping of the useful functions in the house with correspondent domotic sub-systems Nature of elements: Hardware, SoftwareDesign for spatial and temporal independence of elements plug and play, ad-hoc networking, ubiquitous systemsFinancial aspects

Facilities resulting from the integrationone touch controloptimal strategies and control Aesthetics. Remote location control and automated control. Safety and security.Providing control over indoor and outdoor Energy conservation and environmental controls.

What means intelligent device in house?A element able to process information and to react specific at themA element able to communicate with the peoples that populate the houseA element able to communicate with another machine in a network using protocolsA element able to change dynamically the functionalities according to the status of the entire system

Intelligent building components

Facet of implementations of domotic elementsEmbedded solutions (dedicated to implement a function or a set of functions result of hardware and software correlation)Networked solutions (means to correlate a lot of elements and parameters)Software solutions:Specific Generic

Smart objects versus computer assistance

Spontaneous networkingCooperative work

Subsystems of an intellingent house

New Trends in DomoticsAbility of domotic systems to offer a wide range of functions such as: tele-working, monitoring of house parameters (temperature, humidity, illumination, energy consumption, security, access control), e-commerce, e-learning, automatic meter reading (AMR), remote health care monitoring, etc. Transition to a world of servicesTransition to an unified communication system (broad band connections)Developing of generic functions able to discover, manage, and optimize the operation of elements, saving energy and row materialsScalability of system developed (hardware and software)Versatility and re-configurability of systems developed

Functions that can be offered now in houseAutomation of the majority of systems located in house Using personal computers, PDA or mobile phones it is now possible to make the shopping to learn without any temporal or spatial restriction, to pay the invoice for electricity, water, gasUsing monitoring systems for main parameters like: pulse, respiratory and cardiac rhythms, temperature, ECG.

Transition to a world of servicesTele control of the majority functions in houseOffer verified and selected data at demand Offer video, audio at demandMonitor the essential bio-physical parameters for inhabitants of houseImprove the services related to utilities provided for the house by an adequate chose of the provider for each of them (energy, water, gas, etc.) and by an optimal management.
