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 v Smart Demo

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

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)

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

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

Module 3 Serially interfaced appliance control mechanism Circuit : Part I

Module 3 Serially interfaced appliance control mechanism Circuit : Part II (implemented on Veroboard)

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

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
