PLC-Based Automatic Study Chair and Desk System Using Proximity Sensors

Abstract

Many current chairs and study desks often do not meet the ergonomic needs of users, leading to significant physical discomfort and a decrease in productivity. This can cause issues like muscle tension in the neck, shoulders, and back, which ultimately impair concentration. To solve this, an adaptive automation system is proposed. This system is designed to intelligently adjust the height and distance of a chair and desk automatically. The core mechanism uses proximity sensors and a PLC (Programmable Logic Controller). Proximity sensors detect the user's presence and measure their body dimensions in real-time. This data is then processed by the PLC, which instantly calculates and implements the optimal ergonomic position. This innovative system provides a personalized solution, aiming to minimize physical fatigue, save manual adjustment time, and significantly boost user comfort and productivity. The device can serve as an effective tool for creating a healthier and more efficient learning or working environment.
