Project Background:
The project is located in the virtual supermarket of the P&G Venture Center Building in the Science and Technology Park of South China University of Technology in Guangzhou. The construction plan uses radio frequency technology to perform data statistics on the visitors to the supermarket. From the location data of the visitors, the statistics of the visitor’s product access information, a certain product Customer popularity, supermarket customer distribution, special customer tracking, historical trajectory visits and other functions. Jiangsu Tangen Technology uses UWB ultra-wideband positioning technology to promptly build a forward-looking supermarket personnel positioning management system for Procter & Gamble (Guangzhou), which has the significance of a typical application case for supermarket customers.
User background:
Procter & Gamble was founded in 1837 and is the world’s largest consumer goods company. The P&G virtual supermarket is located on the first floor of the P&G Innovation Center in Guangzhou South China Science and Technology Park. The virtual supermarket is divided into three areas: 1. P&G cosmetics supermarket; 2. P&G daily cleaning products supermarket; 3. P&G comprehensive supermarket (newly built ); This project is the positioning of a comprehensive supermarket. The area of this area is about 120 square meters. The commodity shelves are common types of arranged shelves, and visitors walk in various shopping aisles.
solution:
According to P&G’s on-site spatial structure, we use a standard unit indoor sensor to cover the entire area. The sensors are deployed in the four corners of the area, and a relative coordinate system is established according to the on-site environment. Visitors wear ultra-wideband UBIAG7022 compact location tags, a total of 12 tags. Send a pulsed ultra-wideband signal through the tag,sensorAfter receiving the signal from the tag, the real-time positioning coordinates of the tag are calculated according to the TDOA and AOA positioning algorithms. And send the positioning data to the application system via Ethernet. And the system supports the POE function, and the power supply network is also established while establishing the sensor Ethernet network, which greatly reduces the user’s construction cost and construction difficulty.
Implementation results:
The project was completed in September, with a positioning accuracy of about 60cm, which met the expected requirements of users and was well received by users.
