CHAPTER ONE

INTRODUCTION

1.1 STUDY BACKGROUND

Traditionally, a lot of controls in the home and office environments occurs via switches (on / off), tenders and sliders (dimmers) and sometimes motion detectors. These controls can be incorporated in the built environment such as walls, or attached to the lights that people themselves (desk lamps, bedside lamps) Place. This often leads to a tangle of controls each with their own location, interaction style, and focus.

This project is a demonstration of how a PC can be used as a control signal generating subsystem capable of generating programmable control signals for the power equipment. Early studies show that the use of PC power management has often been fou7nd be up to 25% more than Energy Star compliant methods. However, recent evaluations showed higher rates, and estimated that for power management. Switching control is a good replacement for conventional pneumatic or electro chemical control high voltage AC. This equipment is capable not only of control but the energy management and system diagnostic functions. The control PC is inherently more precise control because it reduces maintenance issues and common calibration with pneumatic and mechanical systems. It offers other unique advantages such as coordination of the subsystem, optimal start, diversity analysis and renovation identification.

This design begins with the fact that a computer is required for bulbs high AC rating. This suggests that once an interface of the PC is needed to manage the offset voltage and currents between the PC and the bulbs.

Second, the control data from the computer program logic levels are in series and high frequency format. This time means that the interface must understand the communication protocol and convert it to parallel control necessary scorched. Due to lack of resources, the project will not be real but simulated. This system is more than just a manual on / off control. The system comprises two main components, the output device, and input devices. Output devices work behind the scenes to control lights turning off or on. An input device are to say the switch knob or the sensors.
