Warehouse management method, device and storage medium based on cargo tracking

Abstract

The application discloses a warehouse management method and device based on cargo tracking and a storage medium, and belongs to the technical field of warehouse management. The method comprises the following steps: acquiring a first acquisition timestamp and a first spatial coordinate of cargo collected by a sensor network, reading cargo identity information through a cargo identification unit, determining a second acquisition timestamp and a second spatial coordinate corresponding to the cargo identity information, calculating a time difference between the first acquisition timestamp and the second acquisition timestamp, calling a warehouse space topology mapping table, calculating a spatial distance between the first spatial coordinate and the second spatial coordinate in a warehouse space coordinate system, verifying a cargo order according to the time difference and the spatial distance, and performing a cargo storage and taking operation of a mobile robot according to a verification result. Through time synchronization and positioning verification, the application eliminates the misposition matching problem of identity information and position information caused by the asynchronization of data collected by two sets of systems, and ensures the accuracy of the mobile robot in taking and placing cargo.
