List of Definitions

API Application Program Interface. Interfaces between the operating system and application programs.

Host Controller Device that attaches between a wall plug and a computer that sends and receives X-10 signals.

Smart device Any piece of electronic equipment that is highly automated, or imitates human intelligence.

X-10 A communications protocol that allows compatible products to talk to each other via the existing 110V electrical wiring in the home.

X-10 Module Hardware that facilitates communication between appliances and an X-10 controller. A module would plug into an outlet, and a lamp, for example, would plug into the module.

ProjectIntroduction

General Problem Statement

GOAL: Develop a home automation system that is accessible via the WWW

Users include vacationing or security-conscience homeowners

System is designed to enable a homeowner to operate lights, appliances and other devices and check if their garage door is open or closed via the web.

General Solution Statement

Software Programmed in Java Three parts to the software

GUI application that can be run on the home computer that controls the X-10 devices from that computer

Java applet that can be run from any web-enabled device that connects to the home computer to control the home network

Java server that controls the devices when the applet has connected to the host computer

Hardware Garage door monitor

Operating Environment

SoftwarePlatform independentClient applet must run on a browser that

supports Java applets

HardwareHost computer must have a serial port to

talk to the X-10 controllerGarage door sensor must be able to

withstand moderate vibration and seasonal temperature and humidity changes

Intended Users

Person who currently owns or will purchase a CM11A host controller

Small businesses that desire the same security/monitoring requirements that our system provides

Intended Uses

Control appliances and lamps locally

Control appliances and lamps remotely

Automate control via timed events

Allows user to check if their garage door is open or closed

Assumptions

Device shall be easy to install, configure, and useUser is familiar with operating a computerUser will have a computer with a serial port and continuous internet access. (dial-up not recommended)Home environment will comply with the specified operating environmentX-10 system will not experience outside interference from other X-10 systems

Limitations

Limited to 16 different X-10 controlled devices

Server must be running on the home computer when the client desires to connect and control remotely

Device response time is limited by the speed of the user’s Internet connection

End Product DescriptionInstallable software package Installation instructions User software Software Documentation Source Code

X-10 Hardware Must be purchased separately (CM11A devices

required)Garage Door Sensor Monitoring module Mounting hardware Installation instructions

Approaches Considered and Ones Used

X-10 Hardware

FireCrackerAdvantages: smaller, no dedicated serial port requiredDisadvantages: less functionality, no 2-way support

ActiveHome CM11AAdvantages: 2-way capable, more uses Disadvantages: more expensive

CM11A chosen because of 2-way functionality

Programming LanguageJava Advantages: Familiar designing GUIs using Java, X-10 API, cross-platformDisadvantages: Slower

C++Advantages: Speed, flexibilityDisadvantages: Not familiar with GUI design, could not find anything like the X-10 API found for Java.

Java chosen because of X-10 API and familiarity

Networking architecture

Stand-alone client/server

Advantages: More secure and stable

Disadvantages: Requires software on each machine

Java Applet

Advantages: Most familiar, easy to use and implement

Disadvantages: Requires Java-enabled browser

Java Applet chosen because it was the best fit for the project

Garage Door Sensor

Buying base sensor and building off of itAdvantages: Quicker and more reliable.Disadvantages: Cost and less known about the

circuit.

Making entire circuitAdvantages: More knowledge of entire circuit.Disadvantages: Time and troubleshooting

Entire circuit was created from scratch, but commercial kit used for testing purposes.

Garage Door CircuitHave the circuit be an X-10 moduleAdvantages: More compact, easier to useDisadvantages: Much more time to design and implement

Have the circuit attach to an X-10 moduleAdvantages: Easier to design, more flexibilityDisadvantages: Requires an external module to function

The circuit will attach to an X-10 module because it allows the team to focus on the garage door circuit itself instead of the X-10 circuitry.

Integration with X-10

Original Approach

Send signal to 2-Way X-10 module

Modified Approach

Create a new power signal from X-10 module based on sensor circuit signal

Implementation Activities Software1) Create local software

- Create GUI- Send X-10 commands- Add/Modify/Remove devices

2) Create remote applet- Create GUI- Add code to send commands- Store on web site with login screen

3) Implement server into local software- Add remote operation functionality into local

software

Implementation Activities Hardware1) Create Infrared Transmission Circuit- Design oscillator- Combine with Infrared LED2) Create Infrared Receiver Circuit- Design amplifier- Design filter- Combine with Infrared Phototransistor3) Combine Transmitter and Receiver Circuits- Create Infrared switch4) Combine infrared circuit with X-10 module- Create proper integration hardware or circuitry
