Matthew Marston SmartHome Interfaces Dr Owen ECE 4884 Centralized Human Interfaces in Smart Homes Introduction Inhouse home automations and centralized control interfaces are a growing trend in housing markets around the world The technology involved and ef ciency of energy tasks and space lend to the name of Smart Home Smart Homes provide a quick and easy solution for networking your home adding advanced security features controlling the in home environment and streamlining tasks and operations with the push of a button Commercial Applications of Smart Home Products The client base for Smart Homes is expanding from the technology savvy to conservationists and even the next generation of home owners In a case study conducted in April 2000 concerning the marketability of Smart Homes 2 45 of 1000 homes surveyed agreed to the statement I am really interested in having the sort of functions a Smart Home could offer Of the questions asked the younger protechnology consumers responded most favorably to Smart Home functions Depending upon if the house is newly built with appropriate wiring or if it is an old house that must be retro t the prices of setting up a Smart Home will cost from less than 100 up to the 10000 s 3 Different Smart Home appliances and applications can suit the user s needs so clients t their houses with these products for security u I 39I39 and y Underlying Technology behind Human Interfaces in Smart Homes X10 UPB The simplest and easiest solution to retro t any home into a Smart Home is using X10 technology Developed in 1975 4 X10 technology uses the power lines already installed in a home to transmit minute signals via a transmitter to different receivers around the house Appliances are plugged in to these receivers and coordinated with the transmitter to allow for remote controlling of any appliance within a wired household network Some noise and phase issues may occur for high powered or motored appliances such as big screen TVs or a vacuum cleaner In the event that there is a problem noise lters and phase lters are available to x them X10 technology is limited to powerline communications and 256 unique controlled modules but is the cheapest solution to retro tting any home 4 UPB or Universal Powerline Bus technology bears many of the same features and limitations of X10 technology but uses more advanced r be d 39 iun 39 39 J between components This allows for 1001000 times faster response times of components and much greater reliability of signals reducing the need for lters 5 UPB is however more expensive in initial cost for transmitters and slightly more expensive in costperproduct Matthew Marston SmartHome Interfaces Dr Owen ECE 4884 Zigbee Z Wave Zigbee and ZWave technologies utilize RF communications for all of their products This low energy lowcost solution is an ideal solution for those retro tting their home who want enhanced control and manageability of their home products While RF provides a highspeed wireless solution the range of Zigbee and ZWave networks are relatively short as starshaped clusters or a mesh of appliances are formed that received and relay transmissions based upon the IEEE 802154 standard 6 Also Zigbee technology requires a Zigbee Network Coordinator to initiate the formation of networks Zigbee Network routers to group the end modules and the Zigbee endmodules themselves such as lights appliances etc 1 While Zigbee and ZWave are a good improvement from X10 technology relatively simple to install they are also more expensive 3 INST EON INSTEON technology utilizes both RF and powerline communications enabling it to communicate with X10 devices as well INSTEON can manage up to 16777216 3 unique modules and each module has its own unique ID allowing for increased security INSTEON utilizes twoway meshes such that a signal is sent from a central node then repeated again from each node that received the first signal then repeated a second and third time in the same manner Because of the nature of these meshes additional modules actually increase the speed and efficiency of the network This is very fast and provides added security range and reliability of signals INSTEON is also very easy to install and relatively inexpensive and as such is considered the best option for integrating objects in a Smart Home Implementation of Centralized Human Interfaces in Smart Homes Utilizing INSTEON technology in a Smart Home several implementations are available to the user Lighting can be controlled individually or paired into groups and can be controlled remotely for each room Temperatures can be set for each room and also be directed to change given the time of day or temperature outside Home theatre systems can be streamlined to a single input for turning on the TV sound system satellite receiver and adjusting the volume levels based upon the ambient noise levels
