Design of Staircase Lighting Automation Circuit Based on PLC Programmable Controller
Using a PLC (Programmable Logic Controller) for the automatic management of stair lighting is an efficient and modern solution for public lighting in staircases. This system offers two main advantages:
1. When a button is pressed on either the upper or lower floor, the lights on each level of the staircase will turn on and off sequentially. Each floor's lighting lasts for 10 seconds, but the timing can be adjusted based on specific needs, helping to significantly reduce energy consumption. This feature ensures that lights are only used when necessary, making it both practical and eco-friendly.
2. Additionally, if multiple people are using the stairs at the same time, the lights will still illuminate each floor in sequence and then turn off automatically. This ensures even distribution of electricity usage among users. Once a user finishes their activity and leaves the area, the system stops measuring electricity consumption for them, making the billing process fair and reasonable.
This PLC-based automation system not only improves the user experience by eliminating the need for manual switching but also enhances energy efficiency and cost control. It is particularly suitable for residential buildings, offices, and other public spaces where stair lighting is frequently used. With its intelligent control and adaptability, this system represents a smart and sustainable approach to lighting management.
