Embodiment Construction

[0059] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0060] The present invention is iBeacon's indoor positioning technology. It uses iBeacon base stations to form a wireless sensor network. Each iBeacon base station is used as a beacon node. The RSSI information is used to calculate the distance between an unknown node and multiple beacon nodes. The Mann filter algorithm determines the location information of unknown nodes.

[0061] The application principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0062] Such as figure 1 As shown, the iBeacon-based indoor positioning method in the embodiment of the present i...

Abstract

The invention discloses an indoor positioning system and method based on iBeacon. IBeacon base stations are utilized to establish a wireless sensor network, each iBeacon base station serves as a beacon node, RSSI information is utilized to calculate distances between an unknown node and multiple beacon nodes, and a self-adaption multilateral positioning and kalman filtering algorithm is utilized to determine the position information of the unknown node. The indoor positioning system is simple in structure, easy and convenient to deploy, low in cost, free of offline calibration, good in positioning stability and high in precision; the problem that the current GPS technology cannot provide indoor positioning service is solved, and indoor positioning and navigating service is provided for a user of a smart phone; online estimation is conducted on path attenuation model parameters according to wireless signal strength information of broadcast of the iBeacon base stations, positioning precision is improved, the problem that the RSSI path attenuation model parameters change along with the environment is solved, therefore robustness of an indoor positioning algorithm is enhanced, and positioning precision is improved.

Description

Technical field [0001] The invention belongs to the technical field of indoor positioning, and in particular relates to an indoor positioning system and method based on iBeacon. Background technique [0002] At present, with the popularity of smart mobile devices (such as smart phones, tablets, and wearable devices, etc.), people’s demand for indoor location information is becoming more and more urgent, and the demand for location-based services is also increasing, such as in exhibition halls. Need to quickly find interesting booths; when waiting at airports, railway stations and other places, you can interact with friends; people are looking for goods and discounts in shopping malls; another example is to find designated departments in hospitals and find free parking spaces in parking lots. Need user location information. Due to the lack of dedicated indoor positioning infrastructure, indoor positioning has always been difficult to achieve. [0003] However, in recent years, wir...
