Embodiment Construction

[0046] In order to describe the present invention in more detail, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] The invention relates to an indoor positioning method for iBeacon base station based on a multi-objective genetic algorithm NSGA-II algorithm for spatial layout optimization technology, and using iBeacon base station and smart phones. Therefore, the present invention mainly includes two parts: one is the space layout optimization technology of iBeacon base stations; the other is the technology for realizing indoor positioning using iBeacon base stations optimized in space layout to improve positioning accuracy and reduce the deployment cost of iBeacon base stations.

[0048] The space layout optimization technology of iBeacon base station is based on the multi-objective genetic algorithm NSGA-II algorithm. It optimizes the shortest distance between the measure...

Abstract

The invention proposes a spatial layout optimization and indoor positioning method for an iBeacon base station based on an NSGA-II algorithm, and the method irons out the defects that the impact on the transmission of a radio frequency signal via the iBeacon base station from an environment, such as a blocking object, is large and the transmission of the radio frequency signal via the iBeacon basestation is not stable. The method employs a genetic optimization algorithm, and designs a spatial layout optimized iBeacon base station deployment scheme, and compensates for the decrease of the positioning precision caused by the instability of the signal to maximum degree. The indoor positioning calculation method provided by the invention employs the data of four base stations for calculatinga to-be-measured point. Compared with a conventional 3-base-station method, the method is more stable and precise in calculation. The method is high in positioning precision, is low in cost, is easy to implement, can be promoted well, and meets the different requirements of positioning precision under the minimum deployment cost through employing a selected optimized equipment deployment scheme.

Description

Technical field [0001] The present invention relates to a technique for optimizing the space layout of iBeacon base stations based on a multi-objective genetic algorithm NSGA-II algorithm, and an indoor positioning method realized by using iBeacon base stations and smart phones. Known iBeacon devices and methods for using smart phones to achieve indoor positioning. Background technique [0002] People living in cities inevitably visit various unfamiliar public places such as shopping malls, airports, hospitals, parking lots, etc. The indoor environment of these public places is complex and unfamiliar. Therefore, people are increasingly demanding indoor accurate navigation and positioning services. strong. For example, when a user needs to find a certain shop while shopping in a shopping mall, or find a parking space or reverse car in a low-level parking lot of a train station, or need to find a lost companion at an airport, the support of indoor positioning technology is require...
