Abstract

Home Automation (HA) systems today are limited in functions that can be performed. HA systems generally are limited to three functions: on, off, and dim/bright. With more and more entertainment devices providing "soft" power on/off and remote control functions, HA systems today are not providing the functions required by the consumer for a totally automated home.

Integration of Personal Computer Based Infra Red Database and Home
Automation Applications

      Home Automation (HA) systems today are limited in functions
that can be performed.  HA systems generally are limited to three
functions: on, off, and dim/bright.  With more and more entertainment
devices providing "soft" power on/off and remote control functions,
HA systems today are not providing the functions required by the
consumer for a totally automated home.

      This article describes a method which enables the HA system to
expand into the area of intelligent control of Infra Red (I/R)
enabled devices.  This is accomplished by moving the I/R code
database out of the individual hand-held remote controls and into the
Personal Computer  (PC) storage.  This now adds I/R capability to the
PC-based HA system.

      By putting the I/R code database into the PC, the PC has the
power and resources to allow manipulation of the I/R code database to
provide complex advanced functions not available in the typical I/R
remote controls.  The PC also provides the ability to upgrade the
database whenever needed instead of purchasing a new remote control.

      With the I/R database in the PC, the hand-held remote controls
for the individual electronic devices can be limited to the logic
necessary to manage the button pushes, thereby, producing a very
inexpensive and true "universal" remote control device.

      Manipulation of the I/R Data Base by the PC opens up many
possible ways to distribute I/R codes throughout the house and to any
remote site.  I/R codes can be translated to enable them to be sent
by a modem over the phone lines, uploaded and sent as data via the
Internet, encoded as radio frequency signals, and encoded to be sent
across the home's electrical power lines.

      The following shows that a method can be established which
allows a PC to send I/R control signals across the electrical wiring
of the home and then broadcast the I/R signal at the selected
destination within the home.  The described methodology is the same
regardless of the  distribution medium.  The power line methodology
directly corresponds to  signals being sent via Radio Frequency (R/F)
to the same type of Home Automation Infra Red receiver module.

      The HA software application will take the selected entries from
the I/R database, translate them to power line data format, and then
distribute the encoded I/R signals to a Home Automation Infra Red
module (HAIR).  HA systems have the ability to selectively send
signals over the  standard electrical wiring of the house.  Specific
destinations are accomplished by first sending a HA address which
matches the address of  the HAIR unit, which is also plugged into the
home's electrical wiring,  and then sending the encoded I/R signal.

      The HAIR module is specific to this application.  This module,
having matched the address, will then take the encoded data and
