Description

Track line device based on RFID

Technical Field

The utility model relates to a track line device field specifically relates to track line device based on RFID.

Background

Radio frequency tags are physical carriers of the electronic code (EPC) of a product, attached to trackable items, which circulate globally and identify and read and write them. The rfid (radio Frequency identification) technology has attracted attention in recent years as a key technology for constructing the internet of things.

Radio Frequency Identification (RFID) is a wireless communication technology that can identify a specific object and read and write related data by radio signals without establishing mechanical or optical contact between the identification system and the specific object. The radio signal is used to transmit data from the tag attached to the article by means of an electromagnetic field modulated at a radio frequency to automatically identify and track the article. Some tags can obtain energy from the electromagnetic field emitted by the identifier during identification, and do not need a battery; there are also tags that have their own power source and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). The tag contains electronically stored information that can be identified within a few meters. Unlike bar codes, radio frequency tags need not be in the line of sight of the identifier, but can be embedded within the tracked object.
