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

  2. Summary • The Home Enhancement Suite is a package that will control various aspects of a room in an autonomous fashion when a user is recognized through RFID. Currently, there are home automation kits available, but generally these do not incorporate different settings for different people. The Home Enhancement Suite will allow a user to automate the lighting as well as set up an HDMI product, such as a television, to their favorite channel and volume.

  3. Updated 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 X10 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 a computer program and the ability to save the "light settings" with the press of a button.

  5. Major Constraints • Cost - Would like to stay under the market price for similar equipment, which is relatively expensive. • Ideally, <$250 for each unit including all necessary peripherals • Variability - Accept many user profiles such that the system is not limited for a large group of people • Efficient - Although not a primary concern, the concept of home automation lends to a “green” initiative and therefore the system should be conscientious of this.

  6. Computation Requirements • Identify user • Display active profile on LCD • Access profile • System will be connected via Ethernet to a PC • Initiate proper protocols • X-10 • CEC-HDMI

  7. Interface Requirements • Up to 3 RFID readers connected via USB • Connect to a PL513 X-10 transmitter via RJ-11 • Connect to a PC via Ethernet • Connect to an electric strike for operating the door lock • Most likely through a 2-pin header

  8. On-Chip Peripherals • Ethernet (1) • Used for connection to PC • USB (1) • Will connect to a HUB controller expanding total USB availability to 4, of which 3 are required • SPI (2) • Interfacing with the PLIX • LCD • General Purpose I/O (3) • Electric strike signal, CEC comm., “user save” • ADC (1) • Ambient light sensor

  9. Off-Chip Peripherals • Serial PLIX - communicates the X-10 protocol to the PL513 • PL513 -- X-10 transmitter connected to AC • USB hub controller IC - Expands the on-chip USB to 4 downline • RFID reader modules - connected via USB to main PCB • Electric strike - Locking mechanism

  10. Power Constraints • Everything will be powered by A.C. • There will be an on-board power supply to provide the appropriate DC signals and necessary current to the electric strike when triggerd • Both a 5V and 3.3V regulator will be used as cost is not a major concern and the system should be as efficient as possible

  11. Packaging Constraints • There are no major constraints • Overall the unit should be unobtrusive and fit on a typical desk top or entertainment stand • The system is not portable and therefore weight and stability are not of primary concern

  12. Cost Constraints • There are no other systems currently available that perform this exact set of tasks. • Other systems tend to include more things (temperature, surveillance, irrigation), but they also require the purchase of additional modules adding up to well over $1000 for basic functionality • The goal is that the Suite remain much less for the included functions. • <$250 per unit

  13. Component Selection • Microcontroller (must meet previously mentioned On-Chip requirements) • PIC32MX664F064L • Ethernet, USB, 4 SPI, 16 A/D, 85 I/O, Internal Oscillator, 512k Flash, 64k RAM • AT32UC3A0512 • Ethernet, USB, 6 SPI, 8 A/D, 109 I/O, Internal Oscillator, 512k Flash, 64k RAM

  14. Component Selection continued • PLIX - only available through Micromint • Ambient Light Sensor • Vishay -- TEMT6000(larger size) or TEMT6200 • Both have similar characteristics, but footprint is different • USB Controller IC • (TI)-TUSB2046B (more readily available) • (Atmel)-AT43301 • Both utilize 1 upstream USB to create 4 downstream
