The present invention pertains to an advanced traction control system designed to enhance the performance of traction elevators. This system integrates multiple components and a novel S-curve algorithm to optimize acceleration and deceleration profiles, ensuring smooth transitions and improved ride quality. Key components include a central controller, motor room board, hall panel controllers, and a car panel controller. The system supports high-speed applications, accommodating speeds up to 1400 feet per minute. The S-curve routine is divided into acceleration, constant speed, and deceleration phases, with digital speed commands transmitted via a serial communication link to the motor drive every 10 milliseconds. This precise control reduces mechanical wear and enhances passenger comfort. The system can adapt to various speed profiles, including normal, short, inspection, and emergency power modes, ensuring optimal performance under different conditions. This invention significantly improves the efficiency, safety, and durability of traction elevator systems.
