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.
