  1. HOME AUTOMATION Armando Roy HOME-NETWORK REMOTE CONTROL

  2. NEWINorth East Wales Institute of Higher Education INTRODUCTION • Objectives • Home-Network • Why Remote Control? • Proposed Home Automation System • X-10 • GSM • Internet Protocol • Interfaces & Middleware • Conclusion

  3. NEWINorth East Wales Institute of Higher Education OBJECTIVES • Develop a Home Automation Remote System • Use different inner and outer network technologies • Use devices that are easy to install • Use low-price materials and devices • Make it suitable for inexperienced users or even disabled people • Make it scalable for further add-ons • Manage multiple control points • Encourage standardization

  4. NEWINorth East Wales Institute of Higher Education HOME-NETWORK Figure 1: The Home-Network

  5. NEWINorth East Wales Institute of Higher Education WHY REMOTE CONTROL? • Enables control from almost anywhere (more comfortable) • Instant alerts greatly increase security • Backup emergency control • Optimal for people with reduced mobility • It can be combined with local control to give higher flexibility. • The network hierarchy has been rapidly moving lower in the chain towards smaller and more personal devices (Canosa, 2001)

  6. NEWINorth East Wales Institute of Higher Education PROPOSED HOME AUTOMATION SYSTEM Figure 2: Proposed Home Automation System

  7. NEWINorth East Wales Institute of Higher Education X-10 • Technique “Power Line Carrier” • Frame sent two times • Noise filter / Phase coupler • Up to 256 controlled devices Figure 3: X-10 frame

  8. NEWINorth East Wales Institute of Higher Education GSM • AT / AT+ commands • Serial connection • SMS • MMS • Dials Figure 4: GSM connection

  9. NEWINorth East Wales Institute of Higher Education INTERNET PROTOCOL • Control Points • IP devices • IP cameras • Web browsers • XML • Siemens UPnP Stack • Addressing • Discovery (SSDP) • Description (XML) • Control (SOAP) • Eventing (GENA) • Presentation (HTML,WML) Figure 5: Siemens UPnP

  10. NEWINorth East Wales Institute of Higher Education INTERFACES & MIDDLEWARE • Middleware • Standard compatible • Link technologies (translation) • Robust • User interfaces (Local & Remote) • Must follow Heuristic Evaluation (Molich and Nielsen 1990) • High usability • Good visibility of system status • Match between system and real world • Error prevention (minimize error messages) • Aesthetic and minimalist • Help

  11. NEWINorth East Wales Institute of Higher Education STATE DIAGRAMS Figure 6: Estate Diagrams

  12. NEWINorth East Wales Institute of Higher Education Conclusion • The E-home is coming quickly • Standards are not completely established • Remote Control is necessary for certain purposes • Developing low-price systems will accelerate the process of turning our homes intelligent • The price of the “intelligence” in a house in comparison with its “body”, is insignificant
