Electronic shelf label system and working mode thereof

Abstract

The invention discloses an electronic shelf label system comprising two parts of an electronic shelf label and a wireless transmission label controller, and the electronic shelf label and the wireless transmission label controller are communicated through a radio frequency transmit-receive unit. A display random access memory of a display is acquired and modified, and a power source control circuit is added at the wireless label of the electronic shelf label, a microcontroller circuit, a memory circuit and a display circuit. The working states of the electronic shelf label are distinguished, particularly the updating and the dormant remaining states of the electronic shelf label are distinguished according to the work characteristics of the electronic shelf label. Through the power source control circuit which adopts a strategy of power source control, the invention solves the problem of unnecessary electric energy consumption when the electronic shelf label is in a dormant working state, and can remarkably reduce the power consumption of the electronic shelf label and prolong the life of a battery of the electronic shelf label.

Description

【Technical field】 [0001] The invention relates to an electronic shelf label system and its working method, in particular to commodity electronic shelf labels applied to logistics and retail industries. 【Background technique】 [0002] The invention relates to an electronic shelf label system and a label. The electronic shelf label system can be applied to display commodity prices, specifications, inventory and various promotional information. As an alternative display device for paper labels, the display content of electronic shelf labels can be more abundant, and the update of prices and other information is more convenient. It can be applied to the display of shelf labels in logistics, retail, especially supermarkets and convenience stores. [0003] In modern large supermarkets or retail stores, due to the wide variety of commodities sold, the price tagging of commodities has become a complex system with a huge workload, and due to industry competition, changes in upstream...
