Abstract

The present invention provides a navigation method and an AGV based on an indoor microwave base station, including the following steps: S1: power on, S2: during the startup process, obtain the absolute position of the AGV through the UWB module of the indoor microwave indoor microwave base station, S3: fully start After the AGV, dispatch the destination command, manually operate the AGV to the top of the two-dimensional code Tag label, accurately obtain the absolute position of the AGV, obtain the position error d and angle error θ of the AGV, and synthesize the fusion error e, S4: When the AGV is in the After the fusion error e is obtained on the two-dimensional code tag label, the position and angle of the next two-dimensional code tag label are adjusted through the inertial navigation system until the next two-dimensional code tag label is reached; when the AGV deviation is too large , out of the established orbit, use the UWB module to obtain the absolute position of the AGV, and dispatch the command to retrieve it. This navigation method has accurate positioning, high precision, low cost, and strong anti-interference ability. It can realize real-time positioning in the working area and facilitate retrieval. .

Description

technical field

[0001] The invention relates to the technical field of route navigation of an automatic guided transport vehicle, in particular to a navigation method based on an indoor microwave base station and an AGV. Background technique

[0002] AGV trolley refers to a transport vehicle equipped with an automatic guiding device, capable of driving along a prescribed guiding path, with safety protection and various transfer functions. The AGV trolley chassis supports and installs various components such as the vehicle drive system and power supply system , assembly, forming the overall shape of the car, so whether the chassis has sufficient load-bearing capacity is very important. The frame of the existing AGV trolley is welded with sheet metal, which can save metal materials, reduce structural weight, and simplify processing and installation procedures. Improve production efficiency, but because the sheet metal is a structure with one side open, the load-bearing capacit...
