The PLC-Based Automated Elevator Control System project focuses on designing and implementing an industrial-grade elevator system that automates vertical movement across multiple floors while ensuring safety, efficiency, and reliability. The system demonstrates practical applications of Programmable Logic Controllers (PLCs) in industrial automation and provides hands-on experience with ladder logic programming, sensor integration, and fail-safe mechanisms. The project uses Siemens LOGO! and Allen Bradley PLCs as the primary controllers. Ladder Logic is employed to design the control logic, including floor selection, door operation, direction control, and emergency stop functions. The PLC continuously monitors inputs from IR sensors positioned at each floor, ensuring precise floor detection and stopping. This sensor integration prevents misalignment or overshoot, enhancing passenger safety. The elevator system also incorporates safety features, such as overload detection, emergency stop buttons, and door obstruction sensors. These features allow the system to handle abnormal conditions efficiently and prevent accidents. Additionally, the control logic is designed for scalability, allowing easy addition of more floors or integration with other industrial automation systems. To ensure efficiency, the system implements optimized floor selection and movement algorithms, minimizing wait times and energy consumption. The project includes both hardware and simulation testing, validating the elevator’s performance under various operational scenarios. By combining PLC programming, sensor integration, and automation principles, this project offers a comprehensive learning experience in industrial control systems. Overall, this project highlights the application of PLCs in real-world automation, demonstrating how programmable logic can enhance safety, reliability, and efficiency in mechanical systems like elevators. It serves as a practical example of combining control theory, sensor technology, and ladder logic programming to create robust industrial automation solutions.
