Tasks in Home Automation


HVAC
Heating, Ventilation and Air Conditioning (HVAC) solutions include temperature and humidity control. This is generally one of the most important aspects to a homeowner. An Internet-controlled thermostat, for example, can both save money and help the environment, by allowing the homeowner to control the building's heating and air conditioning systems remotely.

Lighting
Lighting control systems can be used to control household electric lights in a variety of ways:
  • Extinguish all the lights of the house
  • Replace manual switching with Automation of on and off signals for any or all lights
  • Regulation of electric illumination levels according to the level of ambient light available
  • Change the ambient colour of lighting via control of LEDs or electronic dimmers
Natural lighting
Natural lighting control involves controlling window shades, LCD shades, draperies and awnings. Recent advances include use of RF technology to avoid wiring to switches and integration with third party home automation systems for centralized control.

Audio
This category includes audio switching and distribution. Audio switching determines the selection of an audio source. Audio distribution allows an audio source to be heard in one or more rooms. This feature is often referred to as 'multi-zone' audio.
  • There are three major components that allow listen to audio throughout your home, or business:
    • CAT 5e/ CAT6 cable from a central audio unit.
    • A keypad to control volume and sources.
    • 2 sets of speaker cabling (4ply from amplifier, and 2 ply from key pad to the speakers).
Video
This includes video switching and distribution, allowing a video source to be viewed on multiple TVs. This feature is often referred to as 'multi-zone' video.
Integration of the intercom to the telephone, or of the video door entry system to the television set, allowing the residents to view the door camera automatically.

Security
Control and integration of security systems.
With Home Automation, the consumer can select and watch cameras live from an Internet source to their home or business. Security cameras can be controlled, allowing the user to observe activity around a house or business right from a Monitor or touch panel. Security systems can include motion sensors that will detect any kind of unauthorized movement and notify the user through the security system or via cell phone.
This category also includes control and distribution of security cameras.
  • Detection of possible intrusion
    • sensors of detection of movement
    • sensors of magnetic contact of door/window
    • sensors of glass breaking
    • sensors of pressure changes
  • Simulation of presence.
  • Detection of fire, gas leaks, water leaks (see fire alarm and gas alarm)
  • Medical alert. Teleassistance.
  • Precise and safe closing of blinds.
Intercoms
An intercom system allows communication via a microphone and loud speaker between multiple rooms.
  • Ubiquity in the external control as much internal, remote control from the InternetPCwirelesscontrols (p.ej. PDA with WiFi), electrical equipment.
  • Transmission of alarms.
  • Intercommunications.
Robotics
  • Control of home robots, using if necessary domotic electric beacon.
  • Home robot communication (i.e. using WiFi) with the domotic network and other home robots.

VIA solutions on Digital Home Solutions..

I was casually discussing with a senior executive from VIA and the info I got from him was quite good.

As the widespread usage of consumer electronics and information technology increases, demand is driving the evolution of technology for the home in areas including Internet connection, storage, software, applications, operating systems, and hardware platforms. These networked technologies make home entertainment, security surveillance, and automation control easier, and enable the convenient sharing of resources with the whole household.


VIA employs its expertise in x86 computing technologies, digital media processing, networking and connections to operate in digital home and poises itself to take advantage of what promises to be a hot division in embedded computing. VIA's digital home solution is based on the Digital Living Network Alliance (DLNA) standard that facilitates managing and accessing digital media on a network. In addition, VIA offers a convenient set of software tools (VIA Future Life SDK and API) that can be quickly integrated with third party applications.

Staying eco-friendly is VIA's long-lasting policy. VIA converges the PC technologies for digital home solutions, while providing an enhanced digital home experience that is power-efficient, carbon free, and lead free.

Most of the vendors are empahsising on GO GREEN...

Adobe FlashLite 4.0 overview

Here is the link for Adobe FlashLite 4.0 overview. This is much improved than the previous version.

Do you have any more info, please do contact me.

Home automation

Home automation designates an emerging practice of increased automation of household appliances and features in residential dwellings, particularly through electronic means that allow for things impracticable, overly expensive or simply not possible in recent past decades.

The term may be used in contrast to the more mainstream "building automation", which refers to industrial uses of similar technology, particularly the automatic or semi-automatic control of lighting, doors and windows, Heating, Ventilation and Air Conditioning, and security and surveillance systems.
The techniques employed in home automation include those in building automation as well as the control of home entertainment systems, houseplant watering, pet feeding, changing the ambiance "scenes" for different events (such as dinners or parties), and the use of domestic robots.

Typically, it is easier to more fully outfit a house during construction due to the accessibility of the walls, outlets, and storage rooms, and the ability to make design changes specifically to accommodate certain technologies. Wireless systems are commonly installed when outfitting a pre-existing house, as they obviate the need to make major structural changes. These communicate via radio or infrared signals with a central controller.

Introduction to Digital Home

Digital home refers to a residence with devices that are connected through a computer network. A digital home has a network consumer electronics, mobile, and PC devices that cooperate transparently and simplify usability in the home. All computing devices and home appliances conform to the same standard system in a digital home so that everything can be controlled by a computer. Network sockets are installed in every room like AC power receptacles.

Digital home product companies provide hardware and software, as well as connectivity and supporting technologies, that enable digital content – including music, photos, and video – to be distributed on multiple devices in the home and beyond.

The companies provide a broad range of building blocks for digital home solutions, including chips, reference designs, and software for media center PCs, set-top boxes, digital media adapters, portable media players, and handheld devices.

All the home appliances would include network or peripheral connectivity, such as a USB port, a wired network interface, or a wireless port (i.e. Wi-Fi).
