ABSTRACT
Railway systems are integral to modern transportation infrastructure, but ensuring the safety of trains and passengers remains a paramount concern this paper presents a detailed description of a Railway Anti-Collision System (RACS) designed to automate collision avoidance between trains at multiple plat-forms. The system utilizes an Arduino Nano microcontroller to manage the logical operations, integrating components such as IR sensors, load cells, an I2C LCD display, a buzzer for alerts, and a relay switch for power control. Each component serves a specific function within the system, working cohesively to prevent collisions autonomously. The operational flow of the system is delineated, starting with the detection of a train's approach using IR sensors and confirmation of its presence through load cell readings. Upon detection of an impending collision, signalled by the activation of sensors near the platforms, the system triggers an alert through the buzzer and initiates a power cut-off via the relay switch to prevent further movement. This safety measure remains in effect until a manual reset is performed. Conversely, if no collision is detected; trains are permitted to depart safely, with the system monitoring their movement through sensor readings. Overall, the automation facilitated by the RACS enhances railway safety by pre-emptively detecting potential collisions and taking immediate corrective actions without human intervention. This paper elucidates the functional intricacies of the system, demonstrating its effectiveness in mitigating collision risks in railway environments.
