Electronic label system based on near-distance wireless communication technology, and electronic label updating method

Abstract

The invention discloses an electronic label system based on a near-distance wireless communication technology, and an electronic label updating method. The electronic label system comprises multiple electronic labels, an NFC device and a system server. The electronic labels are respectively placed beside corresponding goods. Near-distance wireless communication is carried out between the NFC device and the system server, and between the NFC device and each electronic label. The electronic label updating method comprises: registering a goods information database in the system server, and downloading the updating content of each electronic label to the NFC device; and holding the NFC device to successively approach each electronic label needing to be updated so as to finish updating of display contents of the electronic labels. The system provided by the invention has the advantages of low power consumption, high communication rate, no communication blind areas, high anti-interference performance and the like. The method provided by the invention has the advantages of convenient operation, high communication reliability and the like. Therefore, the system and method provided by the invention can be widely applied to places such as warehouses, supermarkets and the like.

Description

technical field [0001] The invention relates to an electronic label system based on short-distance wireless communication technology and an electronic label display content updating method based on the electronic label system, belonging to the field of electronic label communication. Background technique [0002] At present, the existing electronic label systems used in supermarkets, warehouses and other places are generally segment code electronic label systems or dot matrix electronic label systems. The advantage is that it supports a variety of wireless frequency band communication, long communication distance, fast wireless communication speed, etc. However, it also has high power consumption in wireless communication, and the communication process is easily interfered. In the process of communication, data errors are not easy to be found, and the coverage of the base station is limited, etc., which urgently need to be further resolved.
