Problems solved by technology

Sometimes, managers have already seen the RFID tags on the inventory items and want to read the information in the tags. In the case of conventional methods, the reader will still read the return signals of multiple tags.

Embodiment

[0032]When the manager cleans up the inventory and sees a specific tag that meets the characteristics of the present invention within the reader's identification range, the manager who holds the RFID reader 1 focuses on the parallel beam source generated by the reader device 3 or a flashlight To irradiate the tag, it is also possible to integrate a parallel beam light source with a suitable spot size in the emission module of the handheld reader to focus on the tag, and make the light intensity of the RFID tag to be read out significantly greater than that of other tags and greater than the threshold energy. Then, the irradiated tag automatically transmits its own information through the coupling element 4, and passes through the reader device 3 to the RFID reader 1, and other RFID tags do not get enough energy and are silent.

Abstract

The invention discloses a data processing system in an environment with radio frequency identification tags densely arranged. The system is composed of an RFID reader, a rear-end data processing system, a reader device, an RFID tag module and a coupling element, wherein the a computer and a database are arranged in the rear-end data processing system, the reader device comprises hardware capable of sending energy of various light beams and sending and receiving information in a wireless mode, and a coil (the coil is an antenna when an RFID tag antenna is not integrated in the RFID tag module) is arranged in the coupling element. The data processing system has the advantages that an RFID reader holder can directly and fast read tag information from a large number of RFID tags through light starting, time is saved, and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic communication, RFID electronic tags, in particular to a data processing system in an environment where radio frequency identification tags are densely arranged, and an information reading and data processing system can be realized in a substation warehouse where radio frequency identification tags are densely arranged. technical background [0002] RFID (Radio Frequency Identification) systems are generally composed of RFID readers and transponders (ie RFID tags). Communication between RFID readers and transponders takes place via electromagnetic fields. Depending on the communication frequency between the RFID reader and the transponder (such as 125KHz, 13.56MHz, 900MHz, etc.), the communication distance between the RFID reader and the transponder is also different. In the case that the transponder does not use an external power source such as a battery (that is, a passive tag), the communication dista...
