Development of Safe and Intelligent Control System of Large Tonnage Overhead Crane Based on Unity Pro
This paper aims at solving the problems existing in hoisting the stator and rotor of hydroturbine unit by overhead crane in hydropower station.Based on Unity Pro,the safe and intelligent control system of large tonnage double trolley overhead crane is developed.Through the development of software and hardware design technology,the problems such as"slipping hook",poor synchronization of double trolley lifting and difficult positioning which have long puzzled the safe operation of the overhead crane are solved.The system has been successfully applied to the 125 t+125 t/18 m overhead crane project of SAN Jawan Ⅲ hydropower station in Peru.Compared with the traditional overhead crane control system,it has significant advantages.
