An electronic tag based on LPWAN and RFID technology

Abstract

The invention relates to the technical field of IOT radio frequency wireless identification, and discloses an electronic tag based on LPWAN and RFID technology. The electronic tag comprises an antenna module, a microprocessor, a cell, an LPWAN transmission module and a trigger module, wherein the antenna module is connected to the trigger module; the antenna module is used for sensing an induction coil; when the electronic tag gets close to the induction coil, an electromagnetic field of the induction coil charges the antenna module so as to enable the antenna module to have energy; the trigger module is used for triggering the electronic tag to send LPWAN signals after sensing that the antenna module has energy; an LPWAN transmission module is used for receiving and sending the LPWAN signals; the cell is used for supplying electric power to the modules of the electronic tag; and the microprocessor is used for processing signals and controlling the LPWAN transmission module to send and receive signals. The electronic tag of the invention cleverly combines a passive electronic tag and an active electronic tag to realize the electronic tag based on the LPWAN and RFID technology.

Description

technical field [0001] The invention relates to the technical field of radio frequency wireless identification of the Internet of Things, in particular to an electronic label based on low power consumption wide area network (LPWAN) and RFID technology. Background technique [0002] With the advancement of technology, the Internet of Things is also developing rapidly; the Internet of Things is a network concept based on the Internet, which extends and expands the client terminal to any item and item for information exchange and communication. Its definition is: through information sensing equipment such as radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners, etc., according to the agreed agreement, any item is connected to the Internet for information exchange and communication, so as to realize intelligent A network concept for identifying, locating, tracking, monitoring and managing. Among all these technologies, radio freque...

AI Technical Summary

Problems solved by technology

[0005] 1. RFID technology belongs to short-distance identification communication, and its communication distance is very short, and the signal coverage of its electronic tags is very limited, which is not conducive to the development of the Internet of Things;

[0006] 2. Traditionally, RFID technology is combined with mobile communication networks to implement the Internet of Things, such as combining 2G / 3G / 4G modules, while mobile communication modules are expensive, high in power consumption, and not wide in coverage, which is also not suitable for the development of physical networks.
