Electronic goods shelf label based on FPGA

Abstract

The invention discloses an electronic goods shelf label based on an FPGA. A 2.4G wireless communication module, a high-resolution electrophoresis type electronic paper display screen, a core controller based on a low-power-consumption FPGA chip, a lithium cell, a power supply circuit, a solar cell panel, an external DC charging module, a temperature-humidity detecting module, an alarming module and a PSRAM display buffer are integrated. Commodity information such as prices, sales promotion and manufacturing factories, one-dimensional bar codes and two-dimensional bar codes of various commodities can be displayed in extremely-high resolution, corresponding commodity inventory information can be displayed, zero power consumption can be nearly achieved, relevant content renewal can be achieved, a brand new and advanced price renewing method is provided for retailing merchants of similar supermarkets, and meanwhile an interface of a commercial POS system is reserved, seamless joint can be achieved conveniently, and an on-line checking function is achieved. The auxiliary temperature-humidity detecting module can monitor environment temperature and humidity in real time, and the alarming module can give an alarm under abnormal situations timely.

Description

technical field [0001] The present invention relates to the field of electronic shelf label systems, and more particularly relates to an FPGA-based electronic shelf label. Background technique [0002] With the vigorous development of the retail industry, there are more and more varieties of goods displayed on supermarket shelves, and various promotional activities in supermarkets also make the prices of goods change more frequently. These have led to supermarkets spending a lot of money on replacing and managing price labels. The price on the shelf label and the price in the POS system are inconsistent due to inevitable mistakes, which eventually lead to customer complaints and damage to reputation abound. It is these reasons that gave birth to the birth of ESL. [0003] Electronic Shelf Label System (ESLs) is an electronic display device placed on a shelf that can replace traditional paper price tags. It is generally used in logistics systems such as supermarkets and war...
