Abstract

The invention relates to a mobile measurement and feedback control system and method of a large crane. The mobile measurement and feedback control system comprises a mobile scanner, an industrial personal computer and a GPS auxiliary device. The industrial personal computer is connected with the mobile scanner and the GPS auxiliary device. The mobile measurement and feedback control system of thelarge crane is used for realizing the automatic hoisting operation of the large crane, can carry out mobile measurement on the hoisting start position, the hoisting target position, and the relative position information, at the hoisting target position, of an aluminum coil groove type wedge position and a hoisted article according to the scanner, and acquires the lifting hook position informationthrough the GPS auxiliary device. The industrial personal computer automatically commands a lifting hook to place the hoisted article in the aluminum coil groove type wedge position through a shortestpath algorithm according to the information mentioned above. The mobile measurement and feedback control system of the large crane can control the large crane to realize intelligent automatic hoisting operation, the working efficiency is improved, and the human cost is greatly reduced; and furthermore, the system can carry out all-weather operation, and in other words, the system can work normally at night or in the weather with bad light.

Description

technical field

[0001] The invention relates to the field of crane machinery, in particular to a movement measurement and feedback control system and method of a large crane. Background technique

[0002] Cranes usually refer to lifting facilities that have lifting capacity and work according to fixed tracks, such as large gantry cranes in docks and hydropower stations, and tower cranes used in construction sites. With the continuous development of social economy, users' requirements for lifting equipment are also increasing, among which safety performance and quality issues are the focus of attention. Moreover, with the continuous innovation of science and technology, some basic automation technology innovations such as wireless communication technology, inspection and sensor technology have been promoted, and modern crane equipment has also been effectively improved.

[0003] In addition, gantry cranes have high requirements for operators. The gantry cranes of the prior a...
