Embodiment Construction

[0043]The present invention consists of two parts, an offline information collection stage and an online positioning stage. The main tasks in the offline stage are: beacon deployment, collection and storage of signal fingerprint information. The main tasks in the online phase are: positioning signal acquisition, data interaction and real-time position calculation. The scheme of the present invention is described as follows:

[0044] Step 1: iBeacon beacon deployment:

[0045] First of all, it is necessary to prepare the floor plan of the building to be laid out, and determine the specific location coordinates of each iBeacon. The overall idea of ​​beacon deployment is to cover the entire space in a triangular grid-like staggered distribution, and try to ensure that users are in an acute or right-angled triangle surrounded by three beacons when they are anywhere in the room. The layout principles are as follows:

[0046] a) For general indoor environments, the distance betw...

Abstract

The invention relates to a high precision indoor positioning method with easy data acquisition; the method comprises the following two portions: an offline information acquisition phase and an online positioning phase; the offline phase main works comprise beacon laying, signal fingerprint information acquisition and storage; the online phase main works comprise positioning signal acquisition, data interaction and real time position calculation. The method combines a signal fingerprint atlas with an indoor wireless signal propagation attenuation model in the positioning phase, thus greatly improving the positioning precision and speed.

Description

technical field [0001] The invention relates to an iBeacon-based low-power bluetooth beacon, in particular to an indoor real-time position perception and positioning method taking into account ease of implementation and positioning accuracy. Background technique [0002] With the close integration of the navigation system and the communication system, the user's navigation and positioning information has generated greater application value. At present, a single positioning and navigation service is changing to a comprehensive location service such as monitoring, management, traffic, entertainment, and rescue. At the same time, due to the continuous improvement of urbanization, people often stay in the indoor environment, location-based services (Location Based Service, LBS) have widely entered people's lives, and are becoming an indispensable part of social life, economic construction, and national defense security. . [0003] In the outdoor environment, satellite navigati...
