Multi-Storey Car Parking System

This paper presents a functional prototype of a Multi-Storey Car Parking System designed to address the growing challenge of limited parking space in densely populated urban areas. As urbanization and vehicle ownership increase, conventional parking solutions become inadequate, leading to congestion, inefficiency, and wasted land. This automated prototype offers an innovative solution by maximizing space utilization and minimizing human intervention. The system features a two-level mechanical structure built using MDF sheets, aluminum pipes, PVC supports, and steel studs for enhanced durability. A lead screw mechanism powered by a PMDC motor and gearbox raises and lowers a platform to transport miniature cars between levels. A rope-and-spring-based reverse mechanism resets the platform after each cycle, improving energy efficiency and reliability. An Arduino Mega 2560 microcontroller controls the system, processing inputs from an RFID reader and keypad for secure access. An I2C LCD display provides real-time system updates. For accurate operation, the prototype integrates an L298D motor driver, infrared (IR) sensors, and limit switches to detect vehicle presence and ensure safe, precise movements. Emphasizing cost-effectiveness, scalability, and efficiency, this prototype demonstrates strong potential for application in commercial buildings, residential complexes, and public spaces, offering a smart solution to modern urban parking problems.
