Abstract

The invention provides an RFID positioning method based on a simulation tag. A traditional positioning model is remodeled, the simulation reference tag is constructed in a positioning area by utilizing a classical signal propagation model, an RSSI value of the simulation reference tag is figured out by utilizing the RSSI value of the reference tag and on the basis of a distance measurement mode, and then the position of a moving object is obtained. The defect that based on an existing RFID positioning method, positioning accuracy distortion happens on the peripheral area of the reference tag is overcome, and development cost is lowered.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to an RFID positioning method based on a simulation tag. Background technique [0002] RFID (Radio Frequency Identification) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets. Radio signals transmit data from a tag attached to an item through an electromagnetic field tuned to a radio frequency to automatically identify and track the item. Some tags can get energy from the electromagnetic field emitted by the identifier during identification, and do not need batteries; there are also tags that have their own power supply and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). Tags contain electronically stored information and can be identified withi...
