DESIGN AND IMPLEMENTATION OF LIGHTING SWITCHING CONTROL SYSTEM
Chapter One:
Introduction
1.1 Background of the Study
Controlling lighting in homes and offices has traditionally relied on switches, dimmer controls, and motion sensors.
Controls can be placed into walls or attached to personal lighting (e.g., desk lamps, bedside lights). This can result in several controls, each with a unique placement, interaction style, and focus.
This project demonstrates how a PC can provide programmable control signals for power equipment. Early studies show that using a PC for power management can cost up to 25% more than utilising energy-efficient solutions.
Recent assessments indicate greater rates, particularly for power management.
Switching control is a viable alternative to traditional pneumatic or electrochemical high voltage AC control. This gadget can control, manage energy, and provide system diagnostics. Compared to pneumatic and mechanical systems, PC control provides more accurate control and requires less maintenance and calibration.
It provides unique benefits such as subsystem coordination, optimal start, diversity analysis, and retrofit identification.

This design requires a computer to light high-AC rated bulbs. A PC interface is necessary to compensate for voltage and current differences between the PC and bulbs.
The PC program’s control data consists of serialised logic levels with high frequency. The interface should grasp the communication protocol and convert it to parallel control signals.
Due to limited resources, the project will be simulated rather than actual. This method allows for more than simply manual on/off control. The system consists of two key components: output device and input device. Output devices control lights by turning them on or off. Input devices are switchers, such as buttons or sensors.
1.2 PROBLEM STATEMENT: – There is no prior information on whether a bulb is dead or not. – One or two poles use the same switch. Each pole requires a switch, potentially incurring significant costs. Each pole has its own switch and location. Moving from one pole to another takes up time. Just turn one or off the light.
1.3 PURPOSE OF STUDY
This professional guide covers using a serial interface hardware based on a microcontroller and max 232 serial converters. Convert and reprogram the high negative -15 volts and +15 volts of the serial RS232 interface to match CPC logic levels. The system controls 3.
Functions include energy management and system diagnostics. Tracking all lighting actions, including bulbs. Prepaid metres can assist cut costs.
1.4 Significance of the Study
This method is crucial since it allows for easy control of connected lights with a single button press. This device allows for easy lighting control while lying in bed.
The technology is safe, allowing children to turn off or on lights when their parents or guardians are not there. The system is crucial for providing immediate access to desired resources. The system tracks all activities (bulb).
1.5 SCOPE OF STUDY.
The project aims to develop a computerised system capable of turning on and off street lights while also controlling power.
The project will address light bit microcontroller difficulties and discrete digital electronics in appliance control.
Intel controllers that can execute applications are often restricted to switches. Time is also considered. The system will optimise user efficiency and convenience.
