AGV hoisting correction system based on guide path and method thereof

Abstract

The invention relates to an AGV hoisting correction system based on a guide path and a method of the AGV hoisting correction system. The AGV hoisting correction system comprises a goods tray, a regular graphic code positioning controller, a tray label code reader, a ground label code reader, a ground regular graphic code label and a tray regular graphic code label, wherein the regular graphic code positioning controller is respectively connected with the tray label code reader and the ground label code reader. The method includes the following steps that a goods tray is put in the center of a tray storage area on an AGV guide path; an AGV enters an image triggering area in the center of the lower surface of the goods tray along the guide path; the regular graphic code positioning controller controls the tray label code reader to collect the tray regular graphic code label and carry out hoisting correction. The AGV hoisting correction system and the method of the AGV hoisting correction system are reasonable in design, achieve the correction function on the goods tray in the process of goods tray hoisting by the AGV on the basis of the guide path, reduce errors of the AGV relative to the goods tray and ensure reliability and stability of AGV transportation.

Description

technical field [0001] The invention belongs to the field of AGV technology, in particular to an AGV lifting correction system and method based on a guiding path. Background technique [0002] AGV is an unmanned fully automatic transport vehicle, which can be widely used in intelligent storage or intelligent parking lot. Under normal circumstances, the working method of the AGV is: before carrying the goods, store the goods pallet in the designated area on the AGV guidance path, and a two-dimensional code label is laid on the ground in the center of the designated area. Before the AGV lifts the goods, Use the QR code label in the center of the pallet storage area to correct the posture of itself and the cargo pallet. When the AGV reaches the target point before putting down the cargo, it also corrects the posture of the cargo storage through the QR code label in the center of the target point. Since the AGV is running, each time it executes a subtask, an error of 1 cm is al...
