Crane cargo unloading sequence automatic generation method and system

Abstract

The invention provides a crane cargo unloading sequence automatic generation method and system, and the method comprises the steps: defining a plurality of unloading regions at the periphery of an initial position before cargo handling according to the relative position relation of the unloading regions relative to the initial position before cargo handling; establishing a three-dimensional spacecoordinate system by taking limit position points of cargos loaded by the crane in three movement directions of large movement, small movement and vertical descending as original points and taking themovement directions of a small trolley, a large trolley and a hoisting mechanism of the crane as X, Y and Z directions respectively; establishing a corresponding relationship between the unloading position and a three-dimensional space coordinate system to obtain an unloading position information database of each unloading area; and formulating an unloading sequence rule for each unloading area,and rearranging the corresponding unloading position information database according to the unloading sequence rule to obtain an unloading sequence database. According to the method, a theoretical research method is organically combined with actual loading and unloading operation requirements and operation characteristics of the crane, and the cargo unloading sequence of the crane is automaticallygenerated.

Description

technical field [0001] The invention relates to the technical field of hoisting and transporting machinery and material handling, in particular to a method for automatically generating a cargo unloading sequence of a crane. Background technique [0002] The lifting equipment used in container ports and container yards is the key equipment for container loading and unloading operations. With the rapid development of port loading volume and large-scale ships, many ports are facing the pressure of shortage of skilled operators and improving the efficiency of loading and unloading operations. Therefore, , Port operators have increasingly prominent demands for automation, intelligence, and automatic lifting equipment that can operate continuously for 24 hours. [0003] In the port or storage yard where large quantities of containers are loaded and unloaded, the lifting equipment needs to continuously complete the loading and unloading operations of batches of containers from the ...
