Intelligent electronic paper label system based on LoRa wireless communication

Abstract

The invention discloses an intelligent electronic paper label system based on LoRa wireless communication, which is an electronic label adopting the Ethernet baud rate of 115200 and the wireless frequency of 433.92 MHz for communication and consists of a label main body, an application server, a control terminal, a base station and a local area network / Internet. The label main body comprises a shell, and a power supply module, an MCU unit, an LORA module for wireless communication, a storage module, a word stock module and an electronic paper ink screen which are arranged in the shell. The system supports a single and batch updating mode at the same time, and compared with a traditional paper label, the system has the advantages of being capable of being recycled, automatically updating information, conducting remote control, conducting searching and positioning, and conducting data collection, transmission and analysis. The intelligent electronic paper label system has the characteristics of low power consumption, energy conservation, environmental protection, high efficiency, convenience, power failure display, real-time updating, paperless property, visualization, digitalization, informatization and intelligentization.

Description

technical field [0001] The invention relates to the field of electronic labels, in particular to an intelligent electronic paper label system based on LoRa wireless communication. Background technique [0002] The Internet of Things is the use of communication technologies such as local networks or the Internet to connect sensors, controllers, machines, people and things together in a new way, forming a connection between people and things, things and things, and realizing informatization, remote management and control. Intelligent network. [0003] Today’s supermarkets, vending machines, etc. generally use paper labels for product price labels. When replacing labels, it requires manpower to go to the site to replace them individually. The replacement is troublesome and remote management of the Internet of Things cannot be realized. Contents of the invention [0004] The main purpose of the present invention is to provide an energy-saving and environment-friendly intellig...
