Thesis Abstract

Abstract
The design and implementation of a lighting switching control system interface is a crucial aspect of modern building automation. This project focuses on developing an efficient and user-friendly interface for controlling lighting systems in commercial and residential buildings. The aim is to enhance energy efficiency, user comfort, and overall convenience through the integration of advanced technology. The proposed system will feature a user-friendly interface that allows occupants to control lighting levels, switch lights on and off, set timers, and create customized lighting scenes. The interface will be accessible through various devices such as smartphones, tablets, and computers, enabling users to manage lighting systems remotely. Additionally, the system will be designed to provide real-time feedback on energy consumption, enabling users to monitor and optimize their lighting usage. The implementation of the lighting switching control system interface will involve the integration of sensors, controllers, and communication devices to create a seamless and intelligent lighting control system. Motion sensors will be utilized to detect occupancy in different areas of the building, automatically adjusting lighting levels to ensure optimal visibility and energy efficiency. Light sensors will also be incorporated to adjust lighting levels based on natural light conditions, further enhancing energy savings. Furthermore, the system will be designed to support scheduling and automation features, allowing users to program lighting scenarios based on time of day, occupancy patterns, or specific events. This will not only improve user convenience but also contribute to energy savings by ensuring that lights are only used when needed. In terms of implementation, the project will involve the selection of appropriate hardware components, development of a user-friendly interface, and integration of software for system control and monitoring. The interface will be designed to be intuitive and easy to use, catering to the needs of both technical and non-technical users. Overall, the design and implementation of the lighting switching control system interface will facilitate efficient lighting control, energy savings, and enhanced user experience in commercial and residential buildings. By integrating advanced technology and user-friendly design principles, the proposed system aims to set a new standard for intelligent lighting control systems in modern buildings.

Thesis Overview

1.1 BACKGROUND OF THE STUDY
Traditionally, high control in home and office environments takes place through switches (on/off), deals and sliders (dimmers) and sometimes motion sensors. These controls can be incorporated in the built environment such as walls, or attached to lights that people place themselves (desk lamps, bed side lights). This often leads to a jumble 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 generation subsystem capable of generating programmable control signals for power equipment. Early studies reveal that using PC for power management was often fou7nd to be up to 25% more than energy star compliant methods. However, recent assessments have found higher rates, and was estimated that for power management.

Switching control is a good replacement for conventional pneumatic or Electro chemical high voltage AC control. This equipment is capable of not only control but energy management and system diagnostic functions. The PC control in inherentlyhas more accurate control because it reduces maintenance and recalibration problems common with pneumatic and mechanical systems. It offers other unique advantages like subsystem coordination, optimum start, diversity analysis and retrofit identification.

This design begins with the fact that a computer is needed to light bulbs of high AC rating. This immediately suggests that an interface of the PC is needed to handle the mismatch in voltage and currents between the PC and bulbs. Secondly the control data from the PC program are logic levels in serial format and at high frequency. This again means that the interface should understand the protocol of communication and convert it to the necessary parallel control singed. Due to lack of resources, the project will not be real but simulated. This system will represent for more than just manual on/off control. The system comprises of two major components, output device, and input device. Output devices work behind the scenes to control the lights by switching them off or on. Input device are the switcher i.e. the button or sensors.

1.2 PROBLEM STATEMEN

•  No prior information whether a bulb is dead or not
• There is always a problem of one or two poles using one switch. That is each  pole with a switch which could amount to lots of expenses. Each pole with  their own switch and location.
•  It consumes ones time in the sense that one will more from one pole to another. Just to put one or off the light...
