Embodiment Construction
[0042]When the crane is carrying out continuous loading and unloading operations of a certain amount of goods, in order to obtain the shortest handling operation path of the crane and finally obtain the sequence order of the loading and unloading operations, it is necessary to calculate, analyze and compare the transportation distances of all theoretically selectable paths. According to the calculation and comparison As a result, the loading position with the shortest transportation distance is selected and stored, and so on, and finally the calculation of all loading positions and unloading positions is completed.
[0043] The number of alternative paths in crane theory increases explosively with the increase in the number of loaded and unloaded goods. Take the handling operation of a crane moving n pieces of goods from m pieces of goods to the designated destination unloading site as an example. Refer to figure 1 , P in the figure 1 , P 2 ,...,P m Respectively represent th...

The invention provides an intelligent optimization method and system for an automatic cargo loading sequence of a crane. The method comprises the following steps: constructing a crane three-dimensional space coordinate system, using position coordinates in a three-dimensional space coordinate system to represent the initial position and the unloading position of the goods so as to form an initialposition information database and an unloading position information database; in combination with actual loading and unloading operation characteristics of the crane, formulating an unloading rule foran unloading position information database, optimizing and generating an unloading sequence automatically, searching effective target loading cargos one by one according to the unloading sequence, and then optimizing and generating the loading sequence automatically. According to the method and system, a basis is provided for subsequent loading and unloading operation path planning through the optimized and automatically generated unloading sequence database and loading sequence database, so that the control instruction of the crane is conveniently and automatically generated, the crane realizes automatic continuous operation and gives full play to the effective operation capability of the crane, and the operation efficiency and the operation safety are improved.
Description
technical field [0001] The invention relates to the technical field of hoisting and transportation machinery and material handling, in particular to an intelligent optimization method for the automatic loading sequence of crane goods. 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. In ports or storage yards where large quantities of containers are loaded and unloaded, lifting equipment needs to continuously complete the loading and unloading operations of batches of containers from the desi...
