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...
