Embodiment Construction

[0058] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0059] Such as Figure 2-4 Shown, a kind of indoor positioning method based on iBeacon and PDR fusion, comprises the following steps:

[0060] S1, using the iBeacon positioning algorithm for positioning:

[0061] First, the positioning terminal receives the RSSI signal sent by the iBeacon base station, and then calculates the straight-line distance d from the positioning terminal to the iBeacon base station according to the RSSI ranging model, and then calculates the plane distance between the iBeacon base station and the positioning terminal according to the height compensation method. When the positioning terminal receives the RSSI signals of more than three different iBeacon base stations, it can obtain the horizontal distance from more than three different iBeacon b...

Abstract

The present invention discloses an indoor location method based on iBeacon and PDR fusion. The method comprises the following steps of: employing an iBeacon location algorithm to perform location: receiving RSSI signals emitted from an iBeacon base station by a location terminal, calculating a linear distance from the location terminal to the iBeacon base station according to the RSSI distance measurement model, and according to the height compensation method, obtaining a planer distance of the iBeacon base station and the location terminal. The indoor location method based on iBeacon and PDRfusion employs the iBeacon base station location provided by the apple company based on the Bluetooth Ble4.0 technology, is low in power consumption and simple in arrangement, and combines a sensor ofa current Android mobile phone with no need for a lot of cost for purchasing of extra devices such as infrared rays and ultrasonic waves so as to greatly save the indoor location cost, and employs aconcept of two indoor location technology complementation to overcome the technical defects and deficiency due to a single location technology and greatly improve the location precision and the stability.

Description

technical field [0001] The invention relates to the technical field of wireless sensor positioning, in particular to an indoor positioning method based on iBeacon and PDR fusion. Background technique [0002] With the continuous development of wireless sensor technology and mobile phone micro sensor technology, people's demand for Location-Based-Services (LBS) is also increasing. Although the current mainstream outdoor positioning technology GPS has met the needs of most people for outdoor positioning, but in indoor positioning, due to the occlusion of buildings, the reflection and attenuation of wireless signals are caused, so that the positioning error is large, which cannot meet people's needs. need. In contrast, the wireless sensor network (WSN) positioning technology based on high precision and low power consumption has been paid attention to and studied by a large number of scientific researchers, and has broad application prospects. In recent years, many research in...
