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

Module 2Decision 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

Module 3Serially 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 3Serially interfaced appliance control mechanism
Circuit : Part I
Module 3Serially 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
