Indoor location system and location method by employing same

Abstract

The present invention relates to the technical field of location, especially to an indoor location system and a location method by employing the same. The system comprises a visible light location lamp, a first intelligent terminal device and a second intelligent terminal device, the visible location lamp is provided with a Bluetooth location beacon, the first intelligent terminal deice is locatedin an area covered with visible light of the visible location lamp, the first intelligent terminal device receives the visible light location signals emitted by the visible light location lamp to obtain the position of the first intelligent terminal device, the first intelligent terminal device is deviated from the area covered with the visible light of the visible light location lamp, and the first intelligent terminal device is provided with the Bluetooth location beacon. Through adoption of the visible light location lamp, the intelligent terminal devices are employed to receive the visible light to achieve indoor visible light location, and when the intelligent terminal devices are deviated from the visible light location lamp, the intelligent terminal devices receives the Bluetooth location beacon installed at the visible light location lamp to achieve indoor Bluetooth location and guide the direction so as to rapidly guide people to arrive at places where the people want to go.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to an indoor positioning system and a positioning method thereof. Background technique [0002] With the rapid rise and development of intelligent communication technology and Internet technology, services based on location identification are receiving more and more attention, and positioning technology is the key to realize location identification services. The current indoor construction area is also getting larger and larger. For example, in large shopping malls, airports and other areas, people tend to lose their way indoors. There is an urgent need for products with positioning and navigation functions to guide people in the direction and quickly guide them to where they want to go. [0003] The existing Bluetooth positioning technology uses the mapping relationship between the signal strength value and the actual distance for positioning. Because the signal strength is gr...

AI Technical Summary

Problems solved by technology

[0003] The existing Bluetooth positioning technology uses the mapping relationship between the signal strength value and the actual distance for positioning. Because the signal strength is greatly affected by environmental factors (temperature, humidity, physical occlusion, etc.), the actual distance value calculated by it is It is also extremely unstable and inaccurate

Therefore, the shortcomings of the existing Bluetooth positioning technology are large positioning errors, low precision, and weak stability.
