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.
