Problems solved by technology

[0002] Since the Bluetooth signal strength itself fluctuates and is easily disturbed by environmental factors (temperature and humidity, indoor space layout, etc.), when using Bluetooth for indoor positioning, the relationship between the Bluetooth signal strength and the actual distance can be established directly through some mapping methods such as fitting. is very inaccurate, and the resulting positioning results will inevitably produce a large error

Embodiment Construction

[0027] The specific implementation of the present invention will be further described below in conjunction with accompanying drawings and examples, but the implementation and protection of the present invention are not limited thereto. Achieved with technology.

[0028] Indoor environments vary greatly, so it is difficult to find a fixed layout of Bluetooth devices suitable for various indoor environments. In this example, statistical methods were used. Even in different indoor layouts, once the layout scheme is determined, the intensity distribution of the entire indoor area will be determined. The indoor area is divided into several small areas, and the Bluetooth intensity distribution of each small area can be determined by a statistical method. The following is a possible layout scheme.

[0029] Arrangement device: After actual testing, the strength of the selected Bluetooth device is relatively stable within the range of m (m=6) meters, and the strength changes signifi...

Abstract

The present invention discloses a Bluetooth indoor positioning method based on statistical matching. The method includes: zoning a position area, particularly, equally dividing an indoor space area into multiple small square areas by preset rules; carrying out statistics of Bluetooth signal intensity, particularly, carrying out statistics for the range of Bluetooth signal intensity near each of the small square areas; positioning a mobile terminal by matching, particularly, matching the statistic range of Bluetooth signal intensity with the received Bluetooth signal intensity by the mobile terminal, thereby determining the location area and achieving positioning. The present invention is applicable for varieties of complex indoor places and has high versatility and practicality.

Description

technical field [0001] The invention relates to indoor positioning technology, in particular to a Bluetooth indoor positioning method based on statistical matching. Background technique [0002] Since the Bluetooth signal strength itself fluctuates and is easily disturbed by environmental factors (temperature and humidity, indoor space layout, etc.), when using Bluetooth for indoor positioning, the relationship between the Bluetooth signal strength and the actual distance can be established directly through some mapping methods such as fitting is very inaccurate, and the resulting positioning results will inevitably produce a large error. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a Bluetooth indoor positioning method based on statistical matching. The present invention arranges several bluetooth devices for transmitting bluetooth signals in a certain indoor area, divides the indoor ...
