AGV control system and method based on two-dimensional code navigation

Abstract

The invention provides an AGV control system based on two-dimensional code navigation. A two-dimensional code array composed of a plurality of two-dimensional codes is arranged in a driving area of an AGV according to a preset mode; each two-dimensional code comprises position information of the position of the two-dimensional code; a visual detection unit on an AGV vehicle-mounted system tracks and positions a two-dimensional code in the advancing process of the AGV, the position of the AGV is confirmed in real time through an upper computer system, the current position of the AGV is uploaded to a background system in real time, an optimal path for reaching a designated place is found through algorithm operation, and related instructions are issued to the AGV. After the AGV control system carries out processing, related operation is executed to reach a designated position to complete the operation, so that the reliability of AGV navigation is greatly improved, the preset path of the AGV trolley can be set at any time by adjusting the setting of the two-dimensional code, and the whole equipment is simple to maintain and reroute and is not easily interfered by external electromagnetic interference.

Description

technical field [0001] The present invention relates to the field of AGV technology, in particular to an AGV control system and method based on two-dimensional code navigation. Background technique [0002] At present, with the continuous improvement of domestic automation technology, AGV (Automated Guided Vehicle) has been widely popularized in logistics, manufacturing and other industries. It can control the AGV to drive along the designated path and automatically load and unload goods. . [0003] The AGV car is usually equipped with automatic navigation devices such as electromagnetic or optical, so that the AGV car can travel along the specified navigation path. At present, laser navigation or magnetic track navigation technology is usually used to set the driving path of the AGV car; [0004] Among them, when the AGV car using laser navigation encounters a large moving object in a narrow section such as corridors and aisles, it will deviate from the set path, and the n...

AI Technical Summary

Problems solved by technology

[0004] Among them, when the AGV car using laser navigation encounters a large moving object in a narrow section such as corridors and aisles, it will deviate from the set path, and the navigation accuracy of the AGV car is limited by the monitoring range of the laser sensor; The travel route of the magnetic navigation AGV car is limited by the laying of the electromagnetic track, and it can only follow the fixed track form. The travel route of the car is relatively simple; and the installation and development costs of laser navigation and magnetic track navigation are high; The positioning method and navigation of AGV put forward higher requirements
