Path planning method and system for bridge concrete distribution and storage medium

Abstract

The invention relates to a path planning method and system for bridge concrete distribution and a storage medium. The planning method comprises the following steps: S1, analyzing the pouring position of a bridge; S2, determining the positions and the number of pouring traversal points based on the analysis result of the pouring position; S3, determining a path weight between the traversal points, and correcting the weight according to a preset factor; S4, integrating a pouring weight matrix and selecting a starting point based on the corrected path weight between the traversal points; and S5, solving sub-problems of the whole pouring process by adopting a dynamic planning method, and finally obtaining an optimal path. Compared with the prior art, the method and system the advantages that various parameters and variables possibly influencing the concrete distribution path are introduced to correct the path, so that the scene adaptability during specific application is remarkably improved; a concrete distribution path is reasonably planned through a distribution port advancing path planning algorithm, and the problem possibly caused by manual control over movement of the concrete spreader is avoided.

Description

technical field [0001] The invention relates to prefabricated bridge path planning technology, in particular to a path planning method, system and storage medium for bridge concrete distribution. Background technique [0002] In terms of concrete distribution, the existing path research is relatively scarce. Scholars have mainly conducted corresponding research on the concrete pouring process in the two types of structures, building structures and mass concrete structures. Based on the concrete pouring path The difference will lead to the different magnitude of the force acting on the formwork and support, the different position of the force, and the symmetry of the concrete pouring load. The researchers believe that it is more important to plan the path by reducing the magnitude of the force or making the position of the force avoid the weak position of the formwork or support. Based on this principle, it has become the path planning mode commonly used now. [0003] For b...

AI Technical Summary

Problems solved by technology

[0003] For bridges, the research on the planning of the concrete pouring distribution path is almost zero, and there are the following problems: 1) On the construction site, the workers basically perform manual visual control, and the distribution path lacks control and system; 2) The placing machine is often located in a If the position stays for too long, the amount of concrete in each position is uneven; 3) There will be a pouring path that causes the beam body to be twisted, such as centrally symmetrical pouring; 4) There will be problems in pouring concrete beyond the beam section
