Embodiment Construction

[0022] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0023] The fingerprint positioning method of the present invention, such as figure 1 Shown, including steps:

[0024] Step S101: Establish communication and transmit signals between the real-time reference point and each access point, and detect the fingerprint information of the real-time reference point in the current environment. The fingerprint information preferably includes time delay and / or power, and the signal is a special positioning signal Or a general pilot signal.

[0025] Step S102: Match the fingerprint information of the real-time reference point in the c...

Abstract

The invention discloses a fingerprint locating method and server. A plurality of sets of fingerprint databases in different environments are previously established. In an actual locating process, the optimal fingerprint database is obtained according to current fingerprint information of real-time reference points, and the current position of a terminal is finally estimated according to the optimal fingerprint database. Thus, the problem that due to the fact that power is prone to being affected by the dynamic change of environments, a traditional method cannot effectively locate in actual application is solved, the locating errors caused by the ossification and the singleness of fingerprint databases in the traditional method are reduced, the accuracy of indoor fingerprint location is improved, and the environmental adaptability of the fingerprint databases is improved.

Description

Technical field [0001] The invention relates to the technical field of mobile communication positioning, in particular to a fingerprint positioning method and server. Background technique [0002] With the development of communication technology, as a part of mobile communication and personal communication services, location services have become more and more important. [0003] Fingerprint positioning technology is a common technology in indoor location services. The traditional fingerprint positioning technology needs to establish a fingerprint database in the early stage, that is, artificially train each reference point to establish a fingerprint database, and then combine the online data with the data in the fingerprint database. Compare and find matching data to achieve positioning. [0004] In the process of using the fingerprint location method, the signal fingerprint information will be greatly affected due to changes in environmental factors such as crowd movement and obsta...
