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 iBeacon-based indoor positioning system and method. Background technique [0002] At present, with the popularity of smart mobile devices (such as smart phones, tablet computers 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. For example, in exhibition halls, Need to quickly find interested booths; while waiting in places such as airports and train stations, you can interact with friends; The user's location information is required. Due to the lack of dedicated indoor positioning infrastructure, it has always been difficult to implement indoor positioning. [0003] However, in recent years, with the rapid development of wireless technology, many indoor positioning technologies have emerged, such as indoor positioning based on RF...
