Automatic rain responsive window closing system in bus

Abstract

The present invention relates to an automatic window closing system for buses, designed to enhance passenger safety and comfort by preventing rainwater ingress through open windows. The system employs a rain sensor to detect precipitation and a microcontroller that selectively actuates motors connected to individual windows. Only windows that are currently open are closed upon rain detection, conserving power and reducing mechanical wear. Each motor assembly is connected via linkages and guided through a motor shaft to control window movement, and solenoid locks are employed to secure the windows post-closure. The system includes manual override buttons at each window and a centralized driver override switch, allowing for both automatic and manual control. Safety is ensured through the inclusion of limit switches, current sensors, and feedback mechanisms to detect window positions and obstructions. The design is modular and scalable, suitable for various types of window mechanisms and bus models. Optional IoT integration allows remote monitoring and predictive activation using GPS and weather data. The invention offers a practical, efficient, and intelligent solution for modernizing bus infrastructure and improving operational reliability in adverse weather conditions.
