Embodiment 1

[0048] like figure 1 As shown, this embodiment proposes an indoor positioning method based on RSSI fingerprint database transplantation, including:

[0049] S1. Array deployment of LED light sources with wireless modules on the ceiling;

[0050] like figure 2 As shown, firstly, LED light sources (03) with wireless modules (02) need to be arrayed and deployed on the indoor ceiling plane (01). At the same time, the deployment of the wireless module (02) can also be realized with the help of the deployed smart lighting system. That is to say, the existing lighting system can be used directly without improving the existing lighting system, which reduces the deployment cost. While serving as an indoor positioning facility, the wireless LED light source can also be used as an infrastructure for smart lighting and wireless access, realizing multiple functions in a system.

[0051] S2, construct RSSI distance model and ceiling plane RSSI fingerprint library;

[0052] Specifically,...

Embodiment 2

[0070] like Figure 4 As shown, correspondingly, this embodiment proposes an indoor positioning system based on RSSI fingerprint library transplantation, including:

[0071] Set up modules for array deployment of LED light sources with wireless modules on the ceiling;

[0072] like figure 2 As shown, firstly, LED light sources (03) with wireless modules (02) need to be arrayed and deployed on the indoor ceiling plane (01). At the same time, the deployment of the wireless module (02) can also be realized with the help of the deployed smart lighting system. That is to say, the existing lighting system can be used directly without improving the existing lighting system, which reduces the deployment cost.

Abstract

The invention discloses an indoor positioning method and an indoor positioning system based on RSSI (Received Signal Strength Indicator) fingerprint database transplantation. The indoor positioning method comprises the following steps: S1, deploying LED (Light Emitting Diode) light sources with wireless modules on a ceiling in an array manner; S2, constructing an RSSI distance model and a ceilingplane RSSI fingerprint database; S3, transplanting the ceiling plane RSSI fingerprint database to the plane where the wireless device to be positioned is located; and S4, positioning the wireless device to be positioned based on the transplanted RSSI fingerprint database. According to the invention, a tedious process of constructing and updating a fingerprint database through manual collection ina traditional wireless positioning scheme is omitted, and a lot of time and manpower consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning, and in particular relates to an indoor positioning method and system based on RSSI fingerprint library transplantation. Background technique [0002] With the rapid development of wireless communication networks, mobile Internet and smart terminals, the demand for location-based services is also increasing. In different complex environments, the reliable and continuous provision of location information services has touched all aspects of people's lives. Therefore, indoor positioning technology as a guarantee for providing location services has also attracted more and more attention. [0003] Although GPS can be used for positioning outdoors, in indoor, underground, densely-built and other scenarios, due to a series of problems such as signal occlusion, attenuation, and multi-channel effects, GPS basically cannot provide positioning services, and other methods can only be used. Indoor ...
