The increased growth in the railway sector has resulted in an increase in the train traffic density across the world. This has resulted in the increase in the number of accidents involving trains. In this paper, the proposed system includes several features which prevent train accidents. It includes automatic speed controlling in curves, collision detection, fire detection, detaching of couch automatically when fire is detected in it, automatic railway gate control and track continuity. This system makes use of IR sensors , raspberry pi , GSM , GPS Module and other embedded systems.
Railway transportation is a crucial part of modern infrastructure, with millions of people and goods relying on it every day. However, railway accidents can have catastrophic consequences, and even small faults in the tracks can lead to disastrous outcomes. Therefore, it is critical to develop advanced safety measures to prevent accidents and detect faults in the tracks.
The proposed project, "Advanced Railway Accident Prevention and Track Fault Detection Module Using Raspberry-Pi, IR Sensor, GPS, GSM," is aimed at improving railway safety by utilizing modern technologies. The system uses IR sensors to detect faults such as cracks and breaks in the tracks and a camera to detect obstacles on the tracks. It also incorporates GPS and GSM modules to track and communicate the location of potential dangers. This project has the potential to significantly improve railway safety, prevent accidents, and reduce downtime caused by track faults. It is an innovative solution that can be applied to railway networks worldwide, ensuring safe and efficient transportation for all. The Raspberry-Pi is a single-board computer that is low-cost, compact, and easy to use. It serves as the central processing unit for the system and is responsible for collecting data from the sensors, processing it using machine learning algorithms, and issuing warnings or alerts based on the analysis.
