Radio frequency identification device and method based on closed metal shell

Abstract

The invention relates to a radio frequency identification device and method based on a closed metal shell; the radio frequency identification device comprises the metal shell, the metal shell is composed of a metal tank body and a metal top cover arranged at the upper end of the metal tank body, and an information identification assembly used for identifying an electronic tag in the metal tank body is installed at the upper end of the metal top cover; the metal top cover is provided with a control box used for installing the information identification assembly, and the electronic tag is fixed on the surface of an identified device. The information identification assembly comprises a radio frequency identification reader arranged on the upper end face of the metal top cover, a connector of the radio frequency identification reader is connected with a receiving and transmitting antenna arranged on the lower end face of the metal top cover through a data transmission piece, and the data transmission piece is used for penetrating through the metal top cover. The invention is designed aiming at the defects of an existing device, shielding of the metal shell to radio frequency signals can be broken through, and the effect of radio frequency identification communication of devices in the metal shell is achieved on the premise that the sealing integrity of the metal shell is guaranteed.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a radio frequency identification device and method based on a closed metal casing. Background technique [0002] Metal shell products widely used in various industries, such as various pressure vessels, are equipped with various equipment, devices or parts inside these metal shells. In order to monitor the identity information of the devices or parts in these metal shells, Using time information, life information or warranty period information, etc., it is necessary to read or write relevant information to the electronic tag packaged on the internal device of the metal case in real time, and judge the status and danger of the identified device according to the software setting rules Active prompting and alarming of the state, such as identifying dangerous states such as non-genuine products, overdue use, or expired products. However, due to the shielding e...

AI Technical Summary

Problems solved by technology

However, due to the shielding effect of the metal shell on the radio frequency signal, the existing radio frequency identification method cannot perform radio frequency communication on the electronic tags packaged on the internal parts of the metal shell from the outside, and cannot achieve real-time monitoring of device status information in the metal shell to protect Equipment or the purpose of ensuring downstream production quality and production safety of equipment
