AGV navigation system based on image identification and wireless network and navigation method thereof

Abstract

The invention relates to the logistics carrying equipment technology field and especially relates to an AGV navigation system based on image identification and a wireless network and a navigation method thereof. The system comprises several AGV individuals and a control bench. Each AGV individual comprises a controller unit, a walking unit, a first wireless unit and a two-dimensional code unit. The control bench comprises a total controller unit, a second wireless unit, a man-machine interface unit and several camera units. Each camera unit sends identified number information and position information to the total controller unit. The total controller unit calculates a deviation of a position coordinate of each AGV individual and a target position, generates a walking route of each AGV individual and makes each AGV individual walk according to the route. A system structure is simple and cost is low.

Description

technical field [0001] The invention relates to the technical field of logistics handling equipment, in particular to an AGV navigation system and navigation method based on image recognition and wireless network. Background technique [0002] The known AGV navigation methods generally have the following types: [0003] Magnetic navigation AGV, laying magnetic strips on the ground, AGV drive unit patrols the line; [0004] Laser navigation AGV, a rotating laser ranging device is installed on the top of the AGV, and a reflector is installed on the walking route. The laser ranging device calculates the position coordinates and yaw angle of the AGV according to the distance and angle relationship of the signal returned by the reflector. memory route comparison to navigate; [0005] Inertial navigation AGV, the inertial navigation device accelerometer and gyroscope are installed inside the AGV body, the yaw angle is integrated according to the output rotational angular velocit...

AI Technical Summary

Problems solved by technology

[0007] The above AGV navigation has various defects. Among them, the ground magnetic strip of the magnetic navigation AGV is easily damaged, and the route needs to be re-laid, which is not easy to change; the laser navigation AGV needs to be able to scan three or more reflective strips at any time , and the laser sensor is expensive; the inertial navigation AGV accumulates more and more errors over time; the GPS navigation AGV needs to be used in an outdoor open environment
