PresentationOnDesign of electronic system for Remote Controlling of Home Appliances Using X10 Technology1Date: 20th May, 2015RAMVEER SINGH RATHOREM.Tech-ED&T (1319037508)1IntroductionHome automation is the residential extension of "building automation". It is automation of the:HomeHousework or Household activity.

Home automation may include centralized control:Lighting of entire house HVAC (heating, ventilation and air conditioning) Appliances and Other systems (Like Home Weather Station, digital receptionist, etc)

Home Automation (HA) provide improved convenience, comfort, energy efficiency and security.

Bringing the Future HomeAutomate chores such as watering your lawn, opening and closingdrapes, controlling your lights and appliances even controlling yourelectric water heaterUse motion sensors to turn on floodlights and cameras outside yourhome. Or turn on lights indoors as you walk from room to room, createan automatic doorbell, and more.Use water sensors to inform you of leaking plumbing, both minor ormajor, while youre at home or away for the day or on vacation. (Whynot have your computer call you to let you know?)Control your lights and appliances remotely via the Internet or atelephoneRemotely adjust your thermostat so you can warm up your home beforeyou get there.Home Automation (HA)With HA you control and monitor devices and informationTrigger things based on time

Security Monitoring doors and windows Fire, smoke, water

What is X10 home automation?X10 is an early home automation technology that was developed by Pico Electronics of Glenrothes in Scotland back in 1975. X10 became popular because it used to be one of the few home automation that could be easily retro-fitted into existing homes without installing additional cabling, and because of it's entry-level quality and pricing. X10 is an open protocol for communication among home automation devices that primarily uses mains wiring for signalling and control, where the signals are superimposed upon the sinusoidal mains waveform. A supplemental radio based X10 protocol is also defined.

Many X10 home automation devices plug into a power point, and then you plug your lights or appliances to be controlled plug into the X10 device. Built-in X10 wall switches and ceiling fixture controllers are also available.

How does X10 home automation work?X10 home automation uses your existing mains wiring to communicate digital data between X10 devices. Bursts ofdata encoded on a 120 kHz carrier are transmitted during the zero crossings of the 50/60 Hz AC voltage waveform, with only one digital bit being transmitted at each zero crossing. X10 digital data comprises an address and a command sent from an X10 controller to an X10 controlled device. More advanced X10 controllers may also query the on/off or level status of each other using the X10 protocol. Special measures need to be taken to help X10 signals pass from one phase to another, or across split phase systems, when this is required. This usually involves using coupling capacitors or an active X10 repeater, or X10 signal amplifiers and a coupling capacitor. Care also needs to be taken to prevent X10 communications from leaking from one house to another along the mains wiring that extends out into the street, and is common among homes. To help prevent this special X10 inductive filters to attenuate X10 signals as they pass out from your home on the incoming mains supply feeds. X10 wired or wireless protocol packets consist of a four bit (one of 16) "house code" followed by one or more four bit "unit codes" (that in combination with the house code create 16*16=256 possible addresses within the same residence) and then a four bit "command". Different house codes often need to be used within the same home to generate enough distinct X10 addresses, and so they are usually not available to help distinguish one X10 house installation from a neighbouring one. What can We do with it?Lights and appliances (direct, power line or wireless)

Software'sLinux (as a server)Linux is an open source and free os. We use Linux os as a server. We can customize linux kernel and make work for new devices.

Mister House (Web Interface)MH is written entirely in Perl. It has a rather strange Object Orientedmethod of coding because MH writes some of it's Perl code at startup. Plenty of examples exist. Mail lists are very friendly and supportive.

Heyu (Control X10 Devive )Heyu is a command-line-based program that you can use to control your homes lights and appliances via X10 devices. Its written in the C computer language. You can, among other things, use Heyu to store a schedule of events and macros in the CM11As memory, which it can execute even when not connected to the computer. In Chapter 13, you build a starter X10 kit by using Heyu.

AdvantagesThe equipment is inexpensive, available through mail order or in specialist electrical shops.It is simple.No new or specialised wiring is required - perfect for addition to existing buildings.It is simple to install - no need for qualified engineers or professionals.It can control up to 256 devices at any one time.There is a huge and growing product range.It is proven - the technology has been around for over 20 years, with millions of users in the USA and other countries.
