Embodiment Construction

[0029] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the structure related to the present invention.

[0030] Aiming at the automatic inspection of textile weaving, the present invention proposes an automatic guided vehicle instead of manual inspection, especially a path planning method under a specific site.

[0031] Firstly, the map is constructed by using topology modeling method according to the textile weaving inspection environment. A two-way breadth search algorithm based on the time factor, and a local two-way closed-loop method is designed to realize the global optimal path planning of multiple automatic guided vehicles and the path re-planning after...

Abstract

The invention discloses an automatic guided vehicle path planning method for routing inspection, which is applied to textile weaving routing inspection. According to the method disclosed in the invention, based on a local bidirectional closed loop and a bidirectional search algorithm, path global optimal planning in textile weaving inspection and path replanning after dynamic obstacle avoidance are effectively solved; the conflict problem of multiple automated guided vehicles in path planning is solved through arrangement and updating of time windows and a conflict negotiation strategy. A proper intelligent system is matched, and therefore the automatic and intelligent transformation and upgrading requirements of a production line in the textile weaving industry can be met.

Description

Technical field [0001] The invention relates to the technical field of automatic guided vehicle path planning, in particular to an automatic guided vehicle path planning method used for inspection. Background technique [0002] In the production process of the textile weaving production line, it is necessary to arrange inspection work to observe whether the textile machine is working normally and whether the fabric being produced is defective. The traditional method is to arrange worker inspections, which has high labor costs, high work intensity, low efficiency of the inspection system, and narrow product inspection coverage areas. In the context of Smart Manufacturing 2025 and Industry 4.0, the textile and weaving production industry urgently needs automation and intelligent upgrades. [0003] Specifically, in the prior art, the patent application with the publication number CN110503260 A discloses an AGV scheduling method based on dynamic path planning. This strategy initialize...
