Presentation Transcript

  1. Home Enhancement Suite • Presenter: Allen Humphreys • William Bouchonnet, Daniel Sabo, Nathan Irvin

  2. Summary • Definition of Design’s Criticality Levels • Components Under Consideration • Failure Modes, Effects, and Criticality Analysis

  3. PSSCs • An ability to detect a user based on RFID and determine which user has priority, displaying the user's identity on an LCD. • An ability to adjust the light intensity to match a user’s settings through X-10 protocol. • An ability to adjust a television set or other HDMI device using CEC-HDMI protocol, to a user's preferred settings. (ON/OFF, Channel, Volume) • An ability to unlock a door when an acceptable RFID is present. • An ability to select/set preferred settings through an embedded web server and the ability to save the "light settings" with the press of a button.

  4. Reliability & Safety Analysis

  5. Reliability & Safety Analysis • High Criticality • Potential Harm to User • Medium Criticality • Irreparable Damage • Low Criticality • Inconvenience, single feature failure

  6. Reliability & Safety Analysis • Power Supply System • Heat • Microcontroller System • Die Complexity • Failure Rate C1 = .56 for 32-bitµC • Ethernet System • Component Complexity • 29 Passive Components
