Active electronic tag system for positioning accurately

Abstract

The invention discloses an active electronic tag system for positioning accurately,Characterized by comprising a plurality of low frequency waking devices, a plurality of electronic tags, a plurality of readers and a background server,the low frequency waking devices are used to wake up the electronic tags. the electronic tags are arranged on the items to be managed, each electronic label is bound to an only ID,the electronic tag sends the ID to readers. The readers receive the ID numbers sent by the electronic labels, the signal strength of the received electronic tag is detected uploads the signal strength and the position coordinates information of the readers to the background server via network;The background server calculates the specific location of the electronic tags according to the uploaded signal strength of the electronic tags and the position coordinates information of the readers.The invention utilizes a plurality of readers and the low frequency waking device and in combine with the detection of the signal strength to locate the specific position of the current labels, and the position of the electronic tags can be accurately locates, the invention satisfies the needs of the development of the modern material system and has a broad application prospects.

Description

technical field

[0001] The invention belongs to the technical field of electronic information communication, in particular to an active electronic label system capable of accurate positioning. Background technique

[0002] RFID (Radio Frequency Identification) technology, also known as radio frequency identification, 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. . At present, RFID technology is widely used in libraries, access control systems, food safety traceability and other fields.

[0003] The most important advantage of RFID systems is non-contact identification, which can read tags through snow, fog, ice, paint, grime, and harsh environments where barcodes cannot be used, and read tags extremely fast, less than 100 milliseconds in most cases. The sketching capability of active RFI...
