Embodiment Construction

[0094] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0095] The flow matrix matching method based on GJB radio frequency identification technology comprises the following steps:

[0096] S1. Build a dynamic feature matrix; the specific implementation method is: build a feature matrix model, the feature matrix of the FM0 pattern is a 10*16 two-dimensional integer array, defined as {{A0101, A0102,...,A0116}, {A0201, A0202 ,...,A0216},...,{A1001,A1002,...,A1016}};

[0097] The content of the above matrix is ​​determined according to two aspects:

[0098] (1) Store 00+, 00-, 01+, 01-, 10+, 10-, 11+, 11-, v+, v- ten types according to FM0 code pattern;

[0099] (2) Determine the magnitude of the feature matrix according to the dynamic threshold; the determination method of the dynamic threshold is: real-time sampling of the feature matrix, with a length of 16 sampling points, sorting according to t...

Abstract

The present invention discloses a pipeline matrix algorithm based on a GJB radio frequency identification technology. The method comprises the following steps: S1: constructing a dynamic feature matrix; S2, building a pipeline matrix, and performing matching summation point by point of the dynamic feature matrix and the pipeline matrix; and S3: decoding the matching summation result. The pipeline matrix algorithm based on a GJB radio frequency identification technology fully employs a parallel matching thinking to improve the checking code efficiency, and is an effective algorithm with high timeliness, small resource waste and high accuracy and dynamic regulation so as to reach the technology index being smaller than -75dB.

Description

technical field [0001] The invention belongs to the technical field of radio frequency identification communication, in particular to a flow matrix matching method based on GJB (national military standard) radio frequency identification technology. Background technique [0002] With the rapid development of the Internet of Things, the application of radio frequency identification is becoming more and more extensive, and the requirements for the identification sensitivity index and reading distance of the radio frequency identification reader are getting higher and higher. In the military field, the industry generally expects a sensitivity index of less than -75dB. However, there are almost no products that can meet this index in the current national military standard products. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art that due to the complex wireless environment, the code detection is likely t...
