AI Technical Summary

Technical Problem

The existing technology lacks a solution for timely and accurate inventory of shelf merchandise without RFID. Manual inventory is inefficient, and RFID is only applicable to some products, making it impossible to fully and accurately manage the quantity of goods on the shelves.

Method used

Millimeter-wave radar terminal equipment is installed on each shelf grid. Through millimeter-wave signal transmission and echo signal collection, combined with wireless base station communication equipment and cloud servers, the actual quantity and out-of-stock quantity of goods are calculated.

Benefits of technology

It enables timely and accurate shelf inventory, reduces the workload of manual statistics, and improves the efficiency of supply chain management. It is applicable to all products, not just those with RFID.

Abstract

Disclosed in the present disclosure are a system, method and apparatus for inventorying commodities on a shelf. In the system, millimeter wave radar terminal devices are each used for: upon receiving a signal transmission instruction, transmitting a millimeter wave signal, collecting an echo signal, calculating the angle and distance of the echo signal, and transmitting the angle and distance of the echo signal to a cloud server by means of a wireless base station communication device; and the cloud server is used for: sending the signal transmission instruction to different millimeter wave radar terminal devices by means of the wireless base station communication device; upon receiving the angle and distance of the echo signal, acquiring space information of a vacant position of a shelf grid where each millimeter wave radar terminal device is located; on the basis of appearance and size information of commodities stored in the shelf grid where each millimeter wave radar terminal device is located, calculating space information needing to be occupied by each commodity; and calculating the number of actual commodities and the number of out-of-stock commodities on the basis of the space information of the vacant position, the space information of the shelf grid, and the space information needing to be occupied by each commodity. The present invention can realize timely and accurate inventory of commodities on the shelf.
