Problems solved by technology

At present, the existing technologies include: one is to deploy multiple positioning base stations indoors, and the base stations can communicate with client devices based on Bluetooth or WiFi technology; in this solution, base station devices need to be deployed at a higher density in each target building, and also Regular maintenance is required, and the cost is too high; the other is to use the positioning scheme of environmental WiFi signal fingerprint matching; this scheme requires that the client device must be able to collect WiFi signal data through the API, which is not feasible on the iOS platform

Embodiment

[0070] In this embodiment, the method and system of the present invention are used to solve the problem that the AGPS positioning accuracy of iOS client users in shopping malls is too low. The error is 65 meters. After the application of this scheme, the final positioning accuracy reaches 5 meters.

[0071] Such as Image 6 As shown, the system of this embodiment includes:

[0072] The positioning data acquisition device is used to collect the WiFi blind guess positioning value of the sampling point in the building, and then obtain the single-layer sampling data; After the sampling point of each layer, upload the single-layer sampling data to the cloud sampling data management unit;

[0073] Cloud sampling database, used to store the single-layer sampling data;

[0074] A cloud sampling data management unit, configured to receive the single-layer sampling data, store it in the cloud sampling database, and call the single-layer sampling data;

[0075] The cloud indoor posit...

Abstract

The invention discloses a method and a system for locating a position in a building. The system includes: a positioning data collection device, configured to collect WiFi blind guess values of sampling points in a building to obtain single-layer sampling data; a cloud sampling database, configured to store the single-layer sampling data; a cloud sampling data management unit, configured to receive the single-layer sampling data, store the data in the cloud sampling database, and call the single-layer sampling data; a cloud indoor positioning service unit, configured to provide positioning and data services to the client positioning program; and a client positioning program unit, configured to call data in the cloud indoor positioning service unit to complete positioning, wherein the positioning data collection device is connected with the cloud sampling data management unit, the cloud sampling data management unit is connected with the cloud sampling database, and the cloud indoor positioning service unit is connected with the client positioning program unit. The system of the invention is low in cost and high in positioning accuracy.

Description

technical field [0001] The present invention relates to the technical field of navigation and positioning, and more particularly relates to a position positioning method and a positioning system in a building. Background technique [0002] When the GPS signal in the building (indoor) is weak or interfered, the GPS positioning accuracy is too low, and the error is usually more than 65 meters. At present, the existing technologies include: one is to deploy multiple positioning base stations indoors, and the base stations can communicate with client devices based on Bluetooth or WiFi technology; in this solution, base station devices need to be deployed at a higher density in each target building, and also Regular maintenance is required, and the cost is too high; the other is the positioning scheme that adopts the fingerprint matching of environmental WiFi signals; this scheme requires that the client device must be able to collect WiFi signal data through the API, which is no...
