IBeacon-based indoor positioning method

Abstract

The invention discloses an ibeacon-based indoor positioning method, which comprises the following positioning steps: S1) arranging positioning labels uniformly in a scene region, wherein the positioning labels adopt low-power-consumption bluetooth iBeacon, and the positioning labels are arranged every an interval of 8-15 m, and the positioning labels are arranged uniformly or are arranged uniformly along the walking route; S2) data acquisition: a hand-held acquisition terminal traverses all reference points in the same direction in the scene region, collects broadcast information sent by the positioning labels, enables the collected broadcast information to form a complete fingerprint database and stores the fingerprint database to a server; and S3) on-line positioning: a user enters a positioning region with a terminal device in hand, the mobile phone terminal receives iBeacon Bluetooth information, positioning matching is carried out on on-line measurement vector and the fingerprint database in the server, and positioning is realized through a quantum swarm intelligent optimization algorithm positioning matching model. The positioning is realized through the quantum swarm intelligent optimization algorithm and the mathematical positioning model obtained from evolution, and thus efficiency and precision of the positioning can be improved.

Description

technical field [0001] The invention relates to an indoor positioning and navigation method, in particular to an iBeacon-based indoor positioning method, which realizes indoor positioning through measurement and judgment of bluetooth signal strength. Background technique [0002] At present, the application of positioning technology is becoming more and more extensive. For outdoor positioning technology, GPS is the mainstream, but for indoor positioning, GPS is interfered by various factors, and the positioning accuracy is poor. GPS is not suitable for indoor positioning. The current mainstream technologies for indoor positioning include: Wireless network, ibeacon, radio frequency identification, geomagnetism, ultrasonic, Zigbee and so on. [0003] Wireless network positioning: mainly used for data transmission between various electronic devices with short distance, low power consumption and low transmission rate, as well as periodic data, intermittent data and low response ...

AI Technical Summary

Problems solved by technology

[0003] Wireless network positioning: mainly used for data transmission between various electronic devices with short distance, low power consumption and low transmission rate, as well as periodic data, intermittent data and low response time data transmission applications, but its cost and higher power consumption

[0004] Radio frequency identification positioning: mainly used for short-distance precise positioning, but the things it transmits and receives are special and do not have communication capabilities, so the scope of use is limited

[0005] Ultrasonic positioning: Although its positioning accuracy is high, its cost is high, it is not suitable for large-scale application, and the system has low fault tolerance and adaptability

[0006] Ultra-wideband positioning: Although its positioning accuracy, system fault tolerance and adaptability are good, its cost is too high

[0007] Geomagnetic positioning: the accuracy of positioning is low, and the terminal position cannot be accurately determined
