With the development of commercial competition, more and more supermarket retailers begin to use scientific methods to analyze consumers' behavioral information and study consumers' behavioral preferences, so as to provide more accurate data support for supermarket operation and marketing services.

Based on UWB indoor positioning technology, it can solve the above problems that traditional personnel management mode fails to solve. Traditional management mode is not only low in management efficiency, but also unable to fundamentally solve the problem of supervision to everyone. The system can fundamentally solve the problems of personnel management, improve work efficiency, improve management mode, and reduce the cost of personnel safety management in supermarkets.

Solution architecture

UWB high-precision positioning system is mainly composed of hardware (base station, label), positioning engine software, and management platform. The system architecture is shown as follows:

The UWB positioning system installs the positioning label on the shopping cart, and the base station is fixed on the wall of the supermarket to avoid the occluders and build a set of UWB positioning system to obtain real-time and accurate position data of the shopping cart. Moreover, the location data information is provided to the upper data platform through the UWB positioning base station, so as to analyze each consumer's shopping behavior and shopping preferences. Based on such data support, the order of shelf placement is adjusted every quarter, so as to improve the overall sales performance of the supermarket.

System composition

Location tag

The location tag is attached to the surface of the location object. When the tag enters the signal coverage range of the base station, it automatically establishes contact with the base station and sends electromagnetic wave signals to determine the location of the tag. Each tag has a unique ID number, which can be used to locate the object, so that the positioning base station can find the actual location through the tag.

Positioning base station

The UWB base station is distributed at the geometric edge of the location area, and the signal coverage is carried out in this area. The main function of indoor positioning base station is to detect label data information and upload it to the server for summary analysis. A positioning system is generally composed of more than three positioning base stations, which can receive UWB signals sent by positioning terminals, analyze the relationship between them, calculate the signal propagation delay, calculate the distance between the pending positioning label and the base station through a specific algorithm, and then transmit to the positioning engine through the wired network or WLAN.
