RFID (Radio Frequency Identification) device

Abstract

The invention discloses an RFID (Radio Frequency Identification) device, which is used for expanding reading / writing distance of an RFID and obtaining position information and / or environment information of the RFID in global range, such as indoor, outdoor open spaces, high-rise intensive region and the like. The RFID device comprises a GPS (Global Position System) collection unit, a main control unit and a communication unit; the GPS collection unit collects the position information and / or environment information of the RFID device by receiving GPS satellite signals and transmits information to the main control unit; the main control unit acquires types of communication information by polling the communication unit, and awakens the communication unit if the communication information is a position acquiring command; and the communication unit transmits effective position information and / or environment information acquired by the GPS collection unit to an appointed monitoring management center through network so as to display the corresponding position and / or track and / or environment of the RFID device according to the information.

Description

technical field [0001] The invention relates to the technical field of electronic labels, in particular to a novel non-RFID active electronic label device and a system thereof. Background technique [0002] At present, compared with passive tags, traditional active tags are slow to update, bulky, and expensive, but the read and write distances are relatively short. Therefore, after decades of development, active tags will be more and more widely used. [0003] However, the existing active electronic tags are generally RFID (Radio Frequency Identification, radio frequency identification) electronic tags, mainly through radio frequency electromagnetic waves and readers to obtain interactive information to transmit data, the read / write distance is short, about 100 meters to 1500 meters, In addition, the tag is relatively immobilized, the transmission distance is short, and the reader is required to actively read the tag information, especially in the wilderness or unattended ci...
