  2. Presentation Outline • Introduction to Project • Project Activities • Resources and Schedules • Closing Materials

  3. List of Definitions

  4. Project Introduction

  5. 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.

  6. 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

  7. Operating Environment • Software • Platform independent • Client applet must run on a browser that supports Java applets • Hardware • Host computer must have a serial port to talk to the X-10 controller • Garage door sensor must be able to withstand moderate vibration and seasonal temperature and humidity changes

  8. 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

  9. 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

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

  11. 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

  12. End Product Description • Installable 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

  13. Project Activities

  14. Present Accomplishments Software • Created local control software • Created remote Java applet • Implemented server into local software Hardware • Created sensor circuit

  15. Approaches Considered and Ones UsedX-10 Hardware • FireCracker Advantages: smaller, no dedicated serial port required Disadvantages: less functionality, no 2-way support • ActiveHome CM11A Advantages: 2-way capable, more uses Disadvantages: more expensive • CM11A chosen because of 2-way functionality

  16. Programming Language • Java Advantages: Familiar designing GUIs using Java, X- 10 API, cross-platform Disadvantages: Slower • C++ Advantages: Speed, flexibility Disadvantages: 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

  17. 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

  18. Garage Door Sensor • Buying base sensor and building off of it Advantages: Quicker and more reliable. Disadvantages: Cost and less known about the circuit. • Making entire circuit Advantages: More knowledge of entire circuit. Disadvantages: Time and troubleshooting • Entire circuit was created from scratch, but commercial kit used for testing purposes.

  19. Garage Door Circuit • Have the circuit be an X-10 module Advantages: More compact, easier to use Disadvantages: Much more time to design and implement • Have the circuit attach to an X-10 module Advantages: Easier to design, more flexibility Disadvantages: 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.

  20. Research Activities • X-10 protocol • X-10 hardware – CM11A • X-10 APIs and programming • X-10 2-Way functionality • Secure web sites • Trusted Applets • Sensor modules

  21. Design Activities • General System Design • Local Software • Remote Software • Server • Custom Hardware

  22. General System Design Java-enabled PDA or Phone Remote PC Java Applet Web server Control Server • Key: • Team-created Hardware or Software • Commercial X-10 Modules Local PC Local Software Computer Interface Lamp Module Appliance Module Custom X-10 Hardware Living room Lamp Television Sensor

  28. 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

  29. Implementation Activities Software 1) 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

  30. Implementation Activities Hardware 1) Create Infrared Transmission Circuit - Design oscillator - Combine with Infrared LED 2) Create Infrared Receiver Circuit - Design amplifier - Design filter - Combine with Infrared Phototransistor 3) Combine Transmitter and Receiver Circuits - Create Infrared switch 4) Combine infrared circuit with X-10 module - Create proper integration hardware or circuitry

  31. Testing and Modification Activities • Software testing • Test GUI • Test local control functionality • Test remote control functionality • Hardware Testing • Test infrared circuit • Test circuit with X-10 module • System testing • Test local control • Test remote operation • Test garage door sensor with software
