Vision-based Automatic Control System of Overhead Crane

Abstract

The invention relates to an automatic control system of a bridge crane based on vision, and provides a novel control mode of the bridge crane. The control system comprises a bridge crane control system and a vision measurement system, wherein the bridge crane control system and a control circuit based on independently designed and developed control the bridge crane system to operate according to predetermined requirements; and the vision measuring system is used for measuring the load swing angle state of the bridge crane. The novel automatic control system of the bridge crane introduces vision into the load swing angle measurement of the bridge crane to replace a traditional contact swing angle measurement device, a new load swing angle measurement algorithm is proposed based on the novelautomatic control system, the non-contact measurement of load swing angle is realized by computer vision, and the bridge crane system (a laboratory bridge crane experimental platform or an industrialbridge crane platform) can complete corresponding tasks.

Description

technical field [0001] The invention relates to the technical field of automatic control of nonlinear underactuated systems, in particular to a vision-based automatic control system for bridge cranes. Background technique [0002] As we all know, an overhead crane is a very common assembly transportation tool. It uses ropes to connect the load to the trolley on the crane, and transports the load to the designated location through the movement of the trolley. The overhead crane is used in ports, warehouses, etc. , Construction sites and other places have been widely used. [0003] In view of the fact that when the bridge crane is running, the movement of the trolley on the crane will cause the load to swing, so that the load may collide with the surrounding operators or other objects, resulting in damage to the load and even casualties, especially when the trolley After arriving at the designated position and stopping operation, the load suspended by the crane will have a re...
