2 FYP Presentation – the Finale! Project Team : Syed Waqas A Burney, , FCSE (Team Lead) Mutahira Ikram Khan, , FCSE Project Advisor : Mr. Badre Munir, FCSE

3 Agenda : Core Progeny Project Objective Project Modularization The System Overview Architecture Module 1 – Motion Detection & Human Activity Monitoring Module 2 – The Decision Making Software Engine Module 3 – Appliance Control Mechanism & Prototype Modeling Project Status Envisioning Ahead vSmart Demo

4 Core Progeny Computer Vision The branch of applied computing that concerns modeling and developing artificial systems that attain information from images and thereby provide useful functionality and results. Domotics Study of specific automation requirements for homes and application of automation techniques for the comfort, convenience and security of the residents Development Platform :.NET 2.0 Framework (C#)Visual Studio 2005 MS SQL Server 2005

5 Objective Prototyping an integrated system for the smart control of domestic electronic appliances in local environments, based on monitored user presence and activity; thereby achieving multidimensional user- convenience and using modern technology to endow a sustainable environment in our everyday lives. Applications : User Convenience and Energy Saving Offices (lunch hours, after-office timings, etc) Houses (the ‘Digital Home’ concept)

6 Modularization (and timeline) Problem Statement Ideation through innovative techniques/lateral thinking/ brain storming Engineering solutions, and thereby outlining the very FYP definition, field & scope Adopting a research based/experimental approach System design Motion detection and respective human activity monitoring Prototype modeling Serially interfaced appliance control mechanism Decision taking software engine– a multi-threaded expert system Optimization and deployment Completion Nov Jun Dec Jan Mar Apr codename: imaGInation KIeve

16 System Architecture MODULE 2

17 Module 2 Decision taking software engine – an expert system Knowledge Base Design Action Triggering Overlap Calculations Other Parameter Calculations Reaction Generation Serial Transmission

18 Module 2 Decision taking software engine – an expert system The brain of the system– responsible for the actual “monitoring” Decides when to turn off what Expert System : Defining classes for rules Having defined facts in a relational database Using inference techniques to judge which rules, based on user activity, stand, and hence which devices are to be respectively switched off Rules and Facts subject to changes and modifications based on user behavior Overview : Small scale expert system with a dynamically adjusting knowledge base

19 System Architecture MODULE 3

20 Module 3 Serially interfaced appliance control mechanism Connection to Devices : Serial port communication via RS232 Microcontroller Interface circuitry Device Model House. MicrocontrollerInterfaceElectronic DevicesComputer RS232

22 Module 3 Serially interfaced appliance control mechanism Signal serially transmitted by the software Signal interpreted by the microcontroller Devices switched on/off

23 Module 3 Serially interfaced appliance control mechanism Serial Communication Data is transmitted to the microcontroller via RS-232 standard DB- 9 connector is used to connect to the microcontroller Hardware circuitry ATMEL 89C51 MAX 233 2n222 Transistors Diodes 6 volt relays Capacitors Resistors

24 Module 3 Serially interfaced appliance control mechanism Circuit : Part I Software sends data to the serial port Max 233 converts RS-232 to TTL Microcontroller interprets the signal Send signal to the respective ports

28 Module 3 (cntd..) Serially interfaced appliance control mechanism Microcontroller ( ATMEL 89C51): Receives data serially from computer port Processes the data Sends data to its port to which devices are connected Turning relays on and off MAX 233 RS-232 not compatible with today’s microcontrollers Line driver to convert RS-232 signal to TTL logic levels Interface Circuit : BJT based Relay-Driver (2n222): It provides sufficient current to drive the relay Diode : When the relay is switched off, magnetic field generated inside produces a high voltage, which can damage circuit Diode prevents short circuiting when the relay is switched off

29 Module 3 (cntd..) Serially interfaced appliance control mechanism Interface Circuit (cntd..) : Resistor : It prevents flow of high current from the transistor to the ground on the application of VCC Relay : Mechanical relay is used to switch device off
