Design And Implementation Of Shopping Guide System Based On Internet Of Things Technology

With the development of society,supermarkets have become a part of people's daily life.The increase in the variety of goods and the dispersion of the position of goods have brought certain influences on people's purchase of goods,which in turn has spawned an emerging field of intelligent shopping guide.Shopping Guide is a new shopping method based on the Internet of Things.It is designed to facilitate customers' shopping,give customers a new shopping experience,and also facilitate supermarket managers to calculate passenger traffic and supermarket environmental information.The shopping guide system designed and implemented in this paper combines the target of entering the reader signal range by using the RFID tag positioning technology,through the target tag installed in the shopping cart and the preset fixed reader and static reference point.The tag data is combined with the preset static reference point information in the database,and the background data is processed to determine the current location of the customer,and the user location is displayed in the user intelligent terminal platform.The database query method is combined with the RFID positioning technology to search for the goods queried by the customer,thereby locating the location of the product,and simultaneously displaying the customer location and the product location on the user intelligent terminal platform,thereby achieving the shopping guide function.The wireless local area network established by ZigBee technology realizes the networking of all shelves and commodities of the supermarket,as well as the collection of sensor data,and realizes the monitoring of environmental factors such as temperature,humidity and smoke of the supermarket.The main contents of this paper are as follows:First of all,it introduces in detail the increasing social needs of the shopping guide system,as well as the development status of the field,and the growing power of the Internet of Things technology,laying the foundation for the development of intelligent shopping guide system using the Internet of Things technology.Second,the overall design of the system is based on system functional requirements.From the selection of the program to the theoretical analysis,RFID,ZigBee and database were finally used as the core technology for the development of the shopping guide system.The system design is divided into four parts:household intelligent terminal,shelf commodity terminal,supermarket environment monitoring and WEB server.Finally,using UP-Magic210 developed by Beijing Borch as a development platform,QT develops the software of the host computer system and completes the interactive interface of the user intelligent terminal.The shopping guide system developed in this paper is a new shopping guide system based on Internet of Things technology,which effectively solves the problem of supermarket product dispersion,provides users with a new shopping experience,high user experience,and at the same time saves the labor cost of the supermarket to a certain extent.Broad market prospects.
