This includes researching the best method of design and fabricating the design to create a working device. The team considers a smart device as any piece of electronic equipment that is highly automated, or imitates human intelligence (ex. smart missiles). The smart device that the team chose to implement is a home automation system using the X-10 protocol. The team hopes to finish the year with a fully functional home automation system. End Product Description The X-10 Home Automation System will simplify several tasks for a home owner. With home access via the web, maintaining and securing one's home can be easily done from anywhere an internet connection is available. X-10 allows a user to turn off lights, close/open garage doors, and even change the temperature of their home. Introduction GENERAL BACKGROUND • Design, implement, test and demonstrate one or more smart devices chosen by the group • Chosen device is a home automation system using X-10 technology • System includes a host computer to act as a secure web server and X-10 device controller • Appliances connected to the X-10 network will be monitored and controlled via the host PC, website, and/or a web-capable cell phone TECHNICAL PROBLEM • Connect several devices, lights, and appliances to X-10 receivers and monitor and control them via a PC in the home • Extend this control to the internet via a secure web site which allows the homeowner to monitor and control the devices remotely OPERATING ENVIRONMENT • Residential setting • Indoors and/or outdoors • Limited security (neighboring homes on the same electrical transformer may experience interference in their X-10 network) INTENDED USERS • Anyone who wants to be able to control their home from any computer connected to the internet • Anyone who wants extra security associated with home monitoring INTENDED USES • To make the users life simpler by automating everyday occurrences such as turning lights on and off • Create and run macros to control several X10 devices at once • Allow remote monitoring and control via the internet ASSUMPTIONS • Devices shall have a manual override to ensure their functionality when the X-10 network is not working correctly • User shall be familiar with operating a computer • House shall be X-10 compatible (low levels of interference on 110V wiring) • System shall function without the presence of the website for those choosing not to utilize that ability LIMITATIONS • No outside funding for this project • Project shall be completed in two semesters Technical Approach • Design the web page for the home automation system controls • Setup the home network using X-10 protocol • Configure X-10 controllers and sensors What is X-10? X-10 is a communications "language" that allows compatible products to talk to each other via the existing 110V electrical wiring in the home. Controlling Web Site Home Computer Remote Computer Cell Phone X-10 Controller Supports up to 256 devices Key Internet Power Lines Directly connected X-10 wall plugs NOTE: Arrows indicate direction of data flow Lights Sensors Locks X-10 Home Automation System Testing Approach • Testing the home automation system requires the use of the internet, the X-10 controllers/receivers, and devices to control or monitor • Before full system testing, the new software and new hardware will • be tested individually to ensure their functionality • Passing the system test includes full operation of all X-10 devices • and the software shall allow the ability to quickly add new devices Budget and Personnel Effort Design Requirements • DESIGN OBJECTIVES • Create software to provide web based home automation • Develop additional sensors and controls to monitor and control new devices on an X-10 network • FUNCTIONAL REQUIREMENTS • Sensor and control devices shall use X-10 protocol • Software shall be configurable to add new devices • Control and monitoring webpage shall be viewable from any web • browser
