Smart Shopping Cart Fingerprint Locating Using Shelf Label Heartbeats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and maintenance costs of Bluetooth-based locating systems for smart shopping carts in large supermarkets are high due to the need for numerous beacons, and existing solutions complicate the hardware setup.
Innovation Solution
A fingerprint locating method using an electronic shelf label system, where a smart shopping cart collects heartbeat data from shelf labels to construct a locating fingerprint database, reducing hardware complexity and maintenance costs while improving accuracy and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Bluetooth beacons are deployed across all shelf aisles to achieve comprehensive locating coverage, then locating accuracy is improved, but device complexity and maintenance cost increase
Solution Approach 1:
The patent applies multi-functionality by enabling electronic shelf labels to serve dual purposes: their original function for displaying product information and their new function as locating beacons. The shelf labels broadcast heartbeat data packages that contain location information, allowing the same hardware to perform multiple functions without requiring separate Bluetooth beacons for locating purposes.
Solution Approach 2:
The patent merges the locating function with the electronic shelf label system by integrating the heartbeat data package transmission capability into the shelf labels. Instead of having separate Bluetooth beacons for locating, the system combines the product information display and location signaling functions into a single integrated system using the existing shelf label infrastructure.

AI summary
The present disclosure provides a locating method and a locating system for a smart shopping cart, a computer device and a storage medium. The method includes: constructing a locating fingerprint database of an smart shopping cart based on commodity attributes collected by an intelligent device and shelf label heartbeat signals received by a communication module; when a motion sensor obtains the motion data of the shopping cart body, the communication module sends all shelf label heartbeat signals received within a second preset time window to a server; the server matches all the shelf label heartbeat signals received within the second preset time window with the locating fingerprint database to obtain locating information of the smart shopping cart.
