Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the description of the drawings and the specific embodiments.
[0030] Reference figure 1 with figure 2 , An ID-BTS tag identification method based on the QT protocol, it is necessary to introduce a stack S in the reader to record the tag prefix that has collided, and a map associative container M , to record the query prefix N and the number of occurrences T when successfully recognized, and a binary tree BT to record each process node (the path from the root node to each leaf node includes all query prefixes). Initially, the stack S is empty, the map associative container M is also empty, and BT only contains the root node. The basic process of improving the algorithm: including two parts: initial recognition and re-recognition:
[0031] 1) Initial recognition, that is, the reader performs the first round of recognition of all tags within its range. The main steps are as follows:

Provided is an ID-TBS tag identification method based on a QT protocol. A stack S is introduced into a reader, wherein a path of a map associative container M<N,T> and a binary tree BT root node to various leaf nodes comprises all inquired prefixes; initially, the stack S is empty, the map associative container is empty, and BT only contains root nodes. The tag identification method includes: 1) after the initial identification, the reader performs first-round identification on all tags within the range of the reader; and 2) secondary identification: when the reader finishes the first round of identification, the reader needs to perform secondary identification on all tags within the inquiring range. The ID-TBS tag identification method based on the QT protocol effectively solves the problem of collision, and is less in searching times, small in communication amount and high in identification efficiency.
Description
Technical field [0001] The invention relates to the technical field of Internet of Things and information collection and identification, in particular to an ID-BTS tag identification method. In the Internet of Things suitable for digital cities, for special applications such as target tracking and status detection, the reader in the RFID system must repeatedly identify the tags within its query range. Background technique [0002] With the rapid development of communication network technology and computer technology, people have put forward higher requirements for efficient and intelligent city management. The digital city is the product of this stage. Digital city is based on computer technology, multimedia technology and large-scale storage technology, with broadband network as the link, using remote sensing, global positioning system, geographic information system, telemetry, simulation-virtualization and other technologies to carry out multi-resolution, multi-scale , Multi-...
