Distributed wireless electronic label system

Abstract

The invention discloses a distributed wireless electronic label system. The distributed wireless electronic label system is characterized in that the distributed wireless electronic label system includes an upper computer, a ZigBee network and a radio frequency signal transmitting device; the upper computer is used for distributing label display data in a unified manner and confirming label display states; the ZigBee network directly performs data acquisition and monitoring on each node so as to facilitate the management of network node data transmission; the radio frequency signal transmitting device provides radio frequency signals of necessary frequencies for each micro energy acquisition module, so that power supply can be conveniently provided for each module; the upper computer is in wireless or wired connection with the ZigBee network; and the radio frequency signal transmitting device is connected with the ZigBee network through wireless radio frequency signals. The distributed wireless electronic label system has the advantages of real-time update function, low cost as well as convenient management and maintenance.

Description

technical field [0001] The invention relates to short-distance, low-power wireless communication technology, in particular to a distributed wireless electronic label system. Background technique [0002] Paper commodity price tags are widely used in commodity sales. In large supermarkets, there are many types of products and frequent information updates. The management, update and maintenance of paper labels have long relied on manual operations. Contradictions such as confusion are becoming more and more obvious. When there is a lack of supervision or the negligence of the operator, it is easy to have the wrong price of the product, affect the daily sales activities, and even damage the company's image. [0003] With the development of wireless communication technology, especially the emergence of low-power wireless LAN ZigBee technology, many similar technology application products have been produced, such as supermarket shelf labels, warehousing and logistics container ...

AI Technical Summary

Problems solved by technology

This method can effectively solve the power supply problem of the electronic tag, but the battery of the electronic tag needs to be replaced or charged regularly, and the actual maintenance requires a lot of energy

And after the electronic label display information is released by the host computer, if the display is wrong or needs to be modified, it is necessary to go back and forth between the corresponding electronic label node and the central computer room for repeated confirmation, resulting in low actual work efficiency
