Background technique

With the rapid development of economy and technology, supermarkets have become a part of people's daily life. There are various kinds of items in the supermarket, and people can buy any desired commodity in the supermarket. However, the increase in the variety of goods has brought certain impact on people's purchase of goods. People may spend a lot of time looking for goods. At the present stage, people mainly rely on item classification indicators and shopping guides to guide them in searching for items to buy in supermarkets. In many cases, customers cannot find the items they need through the indication signs, or the shopping guides cannot determine the location of the required items, which not only brings inconvenience to the customers, but also increases the work intensity of the shopping guides.

With the development of RFID technology in recent years, RFID technology has been widely used in many fields. Radio frequency identification RFID technology is an automatic identification technology, which uses radio frequency to identify targets through non-contact two-way data communication, and can complete information input, reading and other related operations without close contact, which can effectively identify target identities and other information. The application of RFID technology in supermarkets can allow customers to find the specific location of the goods they need conveniently, quickly and effectively, and calculate the optimal path to the location based on their current location.

Therefore, it is necessary to implement an intelligent supermarket guidance system that can automatically guide customers to the specific location of the purchased goods. This system can bring convenience to the work of relevant supermarket staff, save manpower and material resources, and improve work efficiency.

The RFID reader installed on the shelf collects the RFID electronic tag information on the item through electromagnetic induction, and obtains the current shelf position of the item. The user's current location positioning RFID reader also collects the information of the built-in RFID electronic tag of the customer's handheld terminal through electromagnetic induction to locate the current user's location. The RFID reader-writer installed on the shelf, the customer handheld terminal with built-in RFID electronic tag, and the user's current location location RFID reader-writer are connected to the wireless AP through the wireless network. The shelf item data information server, path navigation server, RFID reader management server, and administrator host computer communicate with the above-mentioned devices through the network. Among them, the functions of each server and upper computer are introduced as follows:

1. Shelf item data information server: This server is used to store detailed information of supermarket items, such as item name, item type, price, production date, shelf location and other information. Before the commodity is put on the shelf, the above-mentioned detailed information of the commodity is entered into the shelf item data information server.

2. RFID reader management server: This server is used to manage the RFID reader installed on the shelf and manage the RFID reader to locate the user's current location.

2.1 The RFID reader installed on the shelf collects the RFID tag number of the product in its reading and writing area. For example, the RFID reader installed on the shelf with the number A-0-1 reads the product name of a certain brand of beverage RFID tag number, such as YLXX0001, YLXX0002, YLXX0003, YLXX0004, YLXX0005 (YL means beverage, XX means the initial letter of the brand name), the RFID reader will transmit the above tag number to the RFID reader management server. When a customer uses a handheld terminal to query the name of XX beverage, it communicates with the RFID reader management server through the network, and the RFID reader management server feeds back the query information, for example, the shelf number is A-0-1. After obtaining the shelf number of the product position, the detailed route information from the customer's current position to the shelf position is fed back through the route navigation server.

2.2 Locate the user's current location The RFID reader is used to obtain the user's current location information. The user brings the customer's handheld terminal with built-in RFID electronic tag close to the reader, and the system can obtain the user's current location. For example, if the ID of the RFID reader at the current location of the user is LA-3-A1, it means that the user is located at the location of the RFID reader at A1 on the third floor. After obtaining the information of the current location of the person, the detailed path information from the customer's current location to the shelf location is fed back through the path navigation server.

3. Path navigation server: This server is mainly used to calculate the optimal path from the user's current reader-writer position to the product's shelf position. According to the above, after obtaining the user's current location information and the shelf location information, the optimal path is calculated.

4. Administrator host computer: the host computer is used to manage the entire smart supermarket system based on RFID technology, including capturing, filtering, collecting, calculating, proofreading, demodulating, data transmission, Data storage and task management, reducing the amount of data transferred from the reader. At the same time, it can provide functions such as interoperability with other RFID supporting software systems.
