Home Automation Home automation is a growing field Many types of automation

technologies exist Most of these technologies are

independent of each other

What is x10?

Power line carrier (PLC) protocol

Allows compatible products to communicate via existing 110V wiring

Why x10?

Inexpensive: 3 Modules/Controller for $50

Universally available

Flexible: modules exist for a large variety of devices

Easy to install: No additional wiring

Alternative: CEBus Noise resistant Higher collision resolution Faster data transmission

Very expensive Limited devices

Consists of 13 bits

Error detection: Each data bit is actually sent twice, in complementary form, on alternate half cycles

How are devices controlled using x10?

Plug appliance into X10 receiver module

Plug the module into electrical outlet.

Set the house and unit codes..

Plug controller (transmitter) into any other electrical outlet in your house

Set the proper house code.

Tuxscreen Why use the Tuxscreen?

Advantages of having one device dedicated to home automation

Memory Expandable Inexpensive $99 Mobile

Linux vs. Inferno Inferno

Does not support needed applications like a compiler

Difficult to use small size

Linux Allows Tuxscreen to run needed program Easy to use Popular small and powerful

Infrared Transmitter Separate from Tuxscreen and

connects to serial port Allows console to control devices

Cost of Prototype Tuxscreen - $99(provided) X-10 modules(provided)

Light modules(2) - $12.95 Appliance modules(1) - $12.99

X-10 controller – $23.95(provided) Ethernet Card - $15.00 IR transmitter components - $20.00 Total cost $190.00

Testing Plan: Phase IBasic x-10 commands will be sent to x-10

modules using console. Observations will be recorded using multimeter and oscilloscope

x-10 commands will be sent to modules with an extra appliance plugged into house wiring to ensure that this device not harmed

All common appliances will be plugged in; all x-10 functions and x-10 modules will be tested for functionality

Testing Plan: Phase IIGoal: Gauge console's user friendliness

and functionality Tests will be performed by three users of

varying computer literacyUsers will be provided a checklist of tasks Users will judge clarity and

understandability Modifications will be made based on user

response

Accomplishments Research Hardware Received Website created Ethernet Program written Command Control Program

Difficulties Tuxscreen

Command Control Program

Tuxscreen Initially serial communication could

not be established with the Tuxscreen

Original operating system could not be backed up

Bootloader could not be uploaded

Tuxscreen Attempted to upload bootloader in

several ways Unlocked Flash Memory Tried contacting people

Tuxscreen#, Message Board, Individuals

Command Control Program Object oriented C++ programming Accepts command inputs from users

and sends appropriate signals to the serial port

Confirmed using an oscilloscope that program sends correct binary data to serial port, but controller does not perform the command

CCP Pseudocode Example of “turn on module1” command lampMenu( int &M) { //lamp menu if(A==1){

if(status==0) //send lamp on commandmodule.setOn(M);

elsecout << already on << endl;

}else if(A==2) {

if(status==1) //send lamp off commandmodule.setOff(M);

cout << already off << endl;}
