Embodiment Construction

[0053] First of all, it needs to be explained that the orientation words such as up, down, left, right, front, and back described in the present invention are only described according to the accompanying drawings, so as to be easy to understand, and are not intended to limit the technical solution and scope of protection of the present invention. .

[0054] like figure 1 and figure 2 Shown is a specific implementation of a navigation system based on a differential wheel set AGV of the present invention, including a navigation path 1 and an AGV 2 . Make the navigation path adopt the navigation magnetic strip set on the ground. The AGV is equipped with four center-symmetrically distributed differential wheel sets and four center-symmetrically distributed magnetic navigation sensors. Among them, the differential wheel set is provided with two symmetrically distributed drive wheels, and the magnetic navigation sensor is used to collect navigation path information. Through the...

Abstract

The invention relates to a navigation system based on a differential wheel set AGV and a control method. The navigation system comprises a navigation path and the AGV, wherein the navigation path is anavigation magnetic stripe arranged on the ground; the AGV is provided with four differential wheel sets distributed in a central symmetry manner and four magnetic navigation sensors distributed in acentral symmetry manner; each differential wheel set is provided with two driving wheels distributed symmetrically; and the magnetic navigation sensors are used for acquiring navigation path information. The navigation system has the advantages of simple structure, low cost, accurate positioning, good stability and high safety; and the control method has the advantages of simple flow, high execution speed, high deviation correction accuracy, stability and reliability.

Description

technical field [0001] The invention relates to an AGV navigation system, in particular to a navigation system based on a differential wheel set AGV, and a control method for the navigation system. Background technique [0002] With the development of science and technology and society, AGV (Automatic Guided Vehicle) has been developed rapidly and widely used. The AGV using the Mecanum wheel can carry out continuous omnidirectional movement, and its automatic navigation is relatively easy to realize. However, the differential wheel AGV cannot be applied to the navigation system based on the Mecanum wheel AGV because it cannot realize continuous omnidirectional motion, and there is no effective navigation system and method for the differential wheel AGV in the art at present. With the application of the differential wheel AGV in the heavy-duty field, there is an urgent need for a navigation system or method suitable for the differential wheel AGV to realize its automatic nav...
