  1. Control System for Smart House Mid Semester Presentation Students Yossi Lempert Albert Achtenberg Instructor Konstantin Sinyuk

  2. Project Description • To create a remote control and monitoring system for an existing “Home Wireless Control” platform • Two kind of remote control: • On Ipaq via Bluetooth • On PC via web access

  3. Controller Access Point Access Point Controller End point End point End point End point Block Diagram

  4. PIC18F458 CAN controller CAN Connection To other Access Points Access Point I2C UART DB of End Points on E2PROM Phillips BT Unit PIC18F452 IPAQ 3870 PC UART UART USB Phillips Bluetooth Unit External Bluetooth Unit USB to CAN adapter Block Diagram (cont.) CAN Bluetooth Bluetooth End point Ipaq Controller PC Controller

  5. Design Tools • Microchip PIC18F452/8 on PICDEM2 boards • MCP 2551 CAN transceivers • MCC18 compiler using MPLab IDE • Philips Bluetooth units • CAN2USB • Protocols Used: • CAN, Bluetooth, HWC Protocol

  6. Components • End Point • Microchip PIC18F452 microcontroller • 40MHz operating frequency • 32Kb Internal Memory • Philips Bluetooth unit attached via UART • Frequencies • The Bluetooth unit’s maximum transfer rate is 750KB/sec • The maximum transfer rate between the PIC and the Bluetooth unit is 115KB/sec • Access Point • Microchip PIC18F458 microcontroller • All of the above • CAN 2.0B peripheral interface • Frequencies • The CAN connection maximum transfer rate is 1MB/sec

  7. Components Cont. • Controllers • HP Ipaq 3870 • External Bluetooth module • Connection via serial port • Windows CE 3.xx • PC • USB to CAN adapter • Web interface

  8. Application Design Ipaq GUI Web Interface Ipaq Module Web Link PC Module BT Module CAN Module Logic HWC Protocol Link

  9. Project modules • Ipaq Module • Using Smart Remote Controller Project by Pavel Vilk and Piotr Drubetskoy • PC Module • Using Access Point simulator on CAN2USB from HWC Project by Ehud Ravitz and Lee Blum

  10. Smart Remote Controller Project by Pavel Vilk and Piotr Drubetskoy • Implementation of a system which includes a single Remote Controller capable of controlling several devices in different rooms via Access Points, connected via LAN. • The Remote Controller and the Access Point are implemented on a PDA with a Blue Tooth link and CE OS. • The Access Point manages a piconet of devices implemented as black boxes on a PC.

  11. HWC Project by Ehud Ravitz and Lee Blum • Aim of the project Create a cheap wireless control network on household appliances. • Create Bluetooth connection between an Access point and an End Point. • Create CAN connection between two Access Points.

  12. Technologies • Ipaq Bluetooth Stack • Ipaq 3870 has no free Bluetooth stack development kit. • Upgrading to Windows Mobile 2003 adds a native Microsoft BT stack that is not supported by the OS. • ZigBee • Expensive development kit • Low Power • Small transfer rate

  13. What have been done so far? • Learning to work with the MPLab and the PIC Development Kit • Learning the Bluetooth Protocol • Learning the CAN Protocol • System and application design • Learning to operate Home Wireless Control project

  14. Schedule • 10.01.2005 – Finish employing HWC project • 10.02.2005 – Build the IPAQ controller • 01.03.2005– Build the PC controller • 15.03.2005 – Final report and presentation
