Intelligent warehouse material positioning management system based on ultra wide band and image coding

Abstract

The present invention provides an intelligent warehouse material positioning management system based on an ultra wide band and image coding. The system comprises: an image coding device comprising animage identification paster and an image identification module, wherein the image identification paster carries image coding information to perform unique identification for cargo, and the image identification module reads the image coding information carried by the image identification paster on the cargo and sends an image identification result to a UWB positioning device; and the UWB positioning device configured to perform positioning of a transportation tool in an intelligent warehouse, determine that the cargo is transported by the transportation tool after the UWB positioning device receives that the image identification result is successfully identified, and determine that the cargo is put down after the UWB positioning device receives that the image identification result is failedin identification. The system is high in positioning precision and low in hardware cost, and can reduce the warehouse management cost.

Description

technical field [0001] The invention relates to the field of UWB indoor positioning and the technical field of image coding recognition, in particular to an intelligent warehouse material positioning management system based on ultra-wideband and image coding. Background technique [0002] With the continuous progress of the economy, the cargo throughput in the logistics field is increasing, and more and more manpower is consumed in physical management. In order to improve the efficiency of cargo management and save manpower and material resources, the demand for cargo positioning management is increasing day by day. [0003] From a technical point of view, UWB can achieve sub-meter positioning accuracy, but due to the large number of general goods in the warehouse, the cost of using UWB tags is too exaggerated, which affects the promotion and popularization. Therefore, the use of UWB and other hybrid positioning methods that cost less than UWB has the ability and demand to r...

AI Technical Summary

Problems solved by technology

[0004] In the existing hybrid positioning management mode based on UWB and Bluetooth, Bluetooth has the disadvantages of high power supply requirements and high cost, and the recycling of tags is also a management overhead

In addition, in the existing mixed positioning management mode based on UWB and RFID identification, passive tags are not easy to identify, and active tags also have power management problems, which brings inconvenience to actual use
