UHF radio frequency identification positioning device

Abstract

The invention relates to the field of electronic tags, in particular to a UHF radio frequency identification positioning device. The antenna comprises an antenna board, a switch network control board,a plurality of antenna array elements and a plurality of radio frequency cables, the plurality of antenna array elements are distributed on the antenna board and are connected with the switch networkcontrol board through a plurality of radio frequency cables; the plurality of antenna array elements are provided with a plurality of independent feeding points, and the switch network control boardis provided with a plurality of radio frequency output ports; and the plurality of independent feeding points are correspondingly connected with the plurality of radio frequency output ports. According to the invention, the antenna array elements are uniformly distributed on the antenna plate; the radio-frequency signals are respectively and correspondingly connected with radio-frequency output ports on the switch network control board through radio-frequency cables; and in combination with the radio frequency switch group, the electronic tag in the identification area can be quickly and accurately positioned, so that the searching difficulty of management personnel is greatly reduced, and the searching and checking time is remarkably shortened, and possibility is provided for real-time elaborate management of valuables in a dense environment.

Description

technical field [0001] The invention relates to the field of electronic tags, in particular to a UHF radio frequency identification positioning device. Background technique [0002] RFID (Radio Frequency Identification) is an information technology widely used in item identification, tracking and management. This technology uses radio frequency energy to spread in space to realize non-contact information transmission, and achieve the identification target through the transmitted information. Since the 1980s, with the development and progress of integrated circuit technology, RFID technology has developed rapidly. At present, RFID products can be found on the market, and the working frequency bands cover the following frequency bands: LF, HF, VHF, UHF (Ultra High Frequency, ultra-high frequency) and microwave frequency bands. [0003] The positioning and identification of objects is one of the most basic and extensive needs of human beings. It is as big as the positioning ...
