Embodiment 1

[0030] as attached figure 1 and attached figure 2 As shown, when the present invention is in use, it is realized by a system built by a control center, more than two radio frequency readers, and more than two tags for marking the object to be measured, wherein the radio frequency for marking the object to be measured The tag sends a signal with its own information according to the established communication protocol; the reader receives and demodulates the signal sent by the tag; the host computer uses the same tag's sent signal received by multiple readers to simultaneously establish a positioning equation;

[0031] The method of the invention is used to solve the equation, and finally output the label position information.

[0032] The method involved in the present invention comprises the steps of:

[0033] 1. The reader receives and demodulates the tag signal, and establishes an initial equation set. Assume that the i-th tag sends a signal to the reader, denoted as s i...

Abstract

The invention relates to the technical field of area positioning, and specifically relates to a positioning method which is accurate in positioning, rapid and based on generalized inverse Broyden rank one correction. The method comprises the steps of: establishing initial equations, receiving arriving time information of labels, and establishing an equation set; utilizing a Taylor formula to carry out linearization on the established non-linear equations, and carrying out iterative solution on the linearized equations till determining that convergence is completed or a maximum iteration number is reached, wherein in order to ensure effective working of the system, the maximum iteration number is no more than 100; and outputting a positioning solution result. Compared with the prior art, the positioning method has the advantages that the operation redundancy is effectively reduced, the structure is reasonable, the operation is simple, the positioning is accurate, etc.

Description

Technical field: [0001] The invention relates to the technical field of regional positioning, in particular to an accurate and rapid positioning method based on generalized inverse Breuden rank-1 correction. Background technique: [0002] The regional positioning system refers to the positioning of personnel and goods in a given area, including: office buildings, warehouses, etc., and has a wide range of applications in the fields of personnel monitoring, cargo management, and logistics. The regional positioning system generally consists of tags, readers and control centers. Among them, the tag transmits wireless signals to the space; the reader receives the information sent by the tag and transmits it to the control center to complete the calculation of the tag's position information. [0003] According to the way the reader receives the information sent by the tag, the regional positioning system can be divided into Received Signal Strength Indication (RSSI), Time of Arri...
