Abstract

A double-lifting-appliance bridge crane pivot angle detection system based on a holographic photography technology is used for detecting the pivot angle situation of a double-hoisting double-lifting-appliance bridge crane and comprises trolley mechanisms arranged on cart mechanisms, a pair of lifting appliances, a pair of panoramic photography devices and a pair of signal processing devices, wherein each trolley mechanism comprises a pair of hoisting motors, each hoisting motor drives a pair of lifting ropes through a rotary shaft, the tops of the lifting appliances are respectively connected with one corresponding pair of lifting ropes, each panoramic photography device comprises a panoramic photography head arranged at the top of the corresponding lifting appliance, and each signal processing device is connected with the corresponding panoramic photography device respectively.The double-lifting-appliance bridge crane pivot angle detection system has the advantages that position information located in a three-dimensional space is acquired through the panoramic photography devices, pivot angle information of the bridge crane is obtained through signal processing of a computer, and the detection system is simple in structure, low in price and high in measurement accuracy.

Description

technical field

[0001] The invention relates to the technical field of visual detection, in particular to a system and method for detecting the swing angle of a double-slinger bridge based on holographic imaging technology. Background technique

[0002] With the development of science and technology, people have higher and higher requirements for the working efficiency of bridge cranes. The operating capacity of bridge cranes is an important symbol of the ability of a port to enter and exit goods. Compared with the traditional bridge crane, the double-lift double-spreader bridge crane is a new type of high-efficiency and high-benefit spreader. During its operation, the movement of the bridge crane will cause the swing of the two loads, which will greatly reduce the In order to improve the working efficiency of bridge cranes, how to do a good job in the anti-sway work of double-lift double-spreader bridge cranes has attracted more and more attention.

[0003] Most of the exi...
