Embodiment 1
[0089] Customer A enters the supermarket and wants to buy items B, C, and D. It is assumed that the supermarket has built an RFID network system according to the scheme proposed by the present invention, and a P2P reader, LED display and RFID positioning system software are housed in the shopping basket.
[0090] The specific implementation of the item positioning and price settlement function is as follows:
[0091] (1) A first selects a shopping basket;
[0092] (2) Select the RFID positioning system software on the display screen of the shopping basket, and enter the keywords of the item B you want to buy;
[0093] (3) The RFID positioning system will return multiple item information containing the keyword of item B for A to choose;
[0094] (4) A chooses an item B;
[0095] (5) The RFID positioning system instantly displays the location of B by searching the RFID database, and obtains the current location of A through the communication between the WSN node arranged in th...
Embodiment 2
[0100] The administrator of the supermarket needs to change the prices of items E, F, and G, assuming that the supermarket has built an RFID network system according to the scheme proposed by the present invention.
[0101] The specific implementation of the price update function of the item is as follows:
[0102] (1) The supermarket administrator modifies the prices of items E, F, and G in the RFID database system;
[0103] (2) The RFID database automatically sends the price modification information of items E, F, and G to the wireless sensor network;
[0104] (3) The wireless sensor network judges whether the price of the item under its jurisdiction needs to be changed according to the radio frequency label information of the item E, F, and G. If so, it will immediately notify the LED display to display the updated price and send a message to P2P for reading The device modifies the label price;
[0105] After the P2P reader receives the wireless sensor network to modify t...

Abstract
The invention discloses a radio frequency network supermarket article information management system and method based on a sensor network and a peer-to-peer network, relates to the technical field of a radio frequency identification (RFID) technique, a wireless sensor network (WSN), light-emitting diode (LED) display and a peer-to-peer network (P2P) and in particular relates to an RFID network system based on the WSN and the P2P. The system comprises a wireless sensor node, a radio frequency tag identification reader, a radio frequency tag, a light-emitting diode display and a radio frequency tag information data base system server, wherein the wireless sensor node is used for managing article information in the peripheral region of the node; the radio frequency tag identification reader is used for reading and writing radio frequency tag information; the radio frequency tag is used for recording prices and name information of supermarket articles; the light-emitting diode display is used for displaying article price information; and the radio frequency tag information data base system server is used for storing and querying all article information. The RFID system is mainly applied to intelligent identification, positioning, price updating, balancing and the like of the supermarket articles. The RFID system is used for solving the problems that the articles are difficult to find out, the price information updating needs manual work to paste and change price tags and the like in the conventional supermarket article management.
Description
technical field [0001] The present invention relates to radio frequency identification (RFID) technology, wireless sensor network (WSN), light emitting diode (LED) display and peer-to-peer network (P2P) technology field, especially relates to a kind of RFID network system based on WSN and P2P, the RFID The system is mainly used in the intelligent identification, positioning, price update and settlement of supermarket items. Background technique [0002] A sensor network is defined as a wireless network composed of randomly distributed tiny nodes integrated with sensors, data processing units, and communication units through self-organization. Wireless Sensor Network (WSN, Wireless Sensor Network) is composed of a large number of cheap micro-sensor nodes deployed in the monitoring area, and forms a multi-hop self-organizing network system through wireless communication. Process the information of the perceived objects in the network coverage area and send it to the observe...
