Embodiment Construction

[0024] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the text of the description.

[0025] Such as Figure 1~2 As shown, the present invention provides an optimization method for improving the accuracy of Bluetooth positioning, including:

[0026] Set up a cache container to obtain and store the gateway data between each gateway and the positioning tag within a time period (preferably a time period of 5-6 seconds) every 3 to 5 seconds, which becomes a calculation cycle. The gateway data is the signal strength value between each gateway and the positioning tag.

[0027] The gateway data is grouped according to the positioning tags, that is, all the gateway data of the positioning tags are listed as a list. When there is no reference gateway point in the cache container, the gateway with the highest signal strength value is selected as the reference gatewa...

Abstract

The invention discloses an optimization method for improving Bluetooth positioning accuracy, and the method comprises the steps: setting a cache container to obtain and store gateway data between eachgateway and a positioning label in a time period at a time, enabling the gateway data to become a calculation period, and enabling the gateway data to be a signal intensity value between each gatewayand the positioning label; Grouping the gateway data according to the positioning tags, selecting the gateway with the highest signal intensity value from the list of the target positioning tags as areference gateway point, storing the reference gateway point in a cache container, and selecting the gateway with the signal intensity value only smaller than that of the reference gateway point fromthe list of the target positioning tags as an auxiliary gateway point; And converting the intensity values between the reference gateway point and the target positioning tag and the intensity valuesbetween the auxiliary gateway point and the target positioning tag into distance values, and calculating the coordinate value of the target positioning tag according to the coordinate positions of thereference gateway point and the auxiliary gateway point. By combining the physical characteristics of the Bluetooth positioning tag and the Bluetooth positioning gateway, the positioning accuracy ofthe Bluetooth positioning tag is improved.

Description

Technical field [0001] The invention relates to the field of Bluetooth positioning. More specifically, the present invention relates to an optimization method for improving the accuracy of Bluetooth positioning. Background technique [0002] On the one hand, Bluetooth positioning technology has rich application scenarios and has the advantages of simple deployment, low power consumption, low cost, safety and reliability. The Bluetooth positioning system consists of a Bluetooth positioning tag, a Bluetooth positioning gateway and a base station system. On the other hand, Bluetooth positioning has greater limitations on positioning accuracy. Regarding the positioning system, continuously improving the accuracy of positioning is of great significance and can spawn more usage scenarios. Summary of the invention [0003] The purpose of the present invention is to provide an optimization method for improving the accuracy of Bluetooth positioning, combining the physical characteristic...
