Commodity movement monitoring method and system based on radio frequency tag signal feature detection

Abstract

The invention discloses a commodity moving monitoring method and system based on radio frequency tag signal characteristic detection. The method comprises the following steps: collecting radio frequency tag data set on a commodity to be detected according to preset period, and obtaining a signal characteristic data flow of a commodity radio frequency tag; processing the signal strength characteristic data in the signal characteristic data flow, obtaining a moving strength index, and judging out that the commodity radio frequency tag corresponding to the moving strength index is an impacted commodity radio frequency tag; processing signal phase characteristic data in the signal characteristic data flow of the impacted commodity radio frequency tag, obtaining a phase change stride value, and judging out that the commodity radio frequency tag corresponding to the commodity phase characteristic data is a moved commodity radio frequency tag and a commodity corresponding to the commodity radio frequency tag is moved. The system can monitor the moving condition the commodities in real time, and is beneficial to manufacturers for timely mastering the market response conditions of new commodities and making proper adjustment for production scale and new product improvement, so as to increase the sales volume.

Description

technical field [0001] The invention relates to a commodity movement monitoring method and system, in particular to a commodity movement monitoring method and system based on radio frequency tag signal feature detection. Background technique [0002] RFID (Radio Frequency Identification) technology, also known as electronic tags, is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets . The radio signal transmits the data from the tag attached to the item through the electromagnetic field tuned to the radio frequency, so as to automatically identify and track the item. Among the three frequency band technologies (low frequency, high frequency, and ultra-high frequency) used by radio frequency automatic identification technology, ultra-high frequency RFID is more widely used. Passive (passive) UHF t...
