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...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned electronic shelf label and electronic shelf label system have the following problems: the electronic shelf label needs to display product information, and various states such as product information update and product information maintenance, especially the power consumption in the product information maintenance state, have not been optimized. and low power consumption design; when the electronic shelf label displays product information such as price, specification, inventory and other information, when the product information needs to be updated, the electronic shelf label system will complete the update of the display content of the electronic shelf label, and in daily applications During the process, the information of the product is displayed in a static state and remains stable. Therefore, it is necessary to distinguish between the update state of the electronic label display data and the display state of the product to reduce the power consumption of the daily static display state; as a part of the electronic shelf label, display The power consumption of the device will always run through the use process of the electronic shelf label, so the low power consumption design of its display circuit and control circuit needs to be considered; the electronic shelf label needs to store commodity information, and the low power consumption design of the storage circuit does not consider
