Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0023] Fingerprint location method of the present invention, as figure 1 shown, including steps:

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

[0025] Step S102, match the fingerprint information of the real-time reference point in the current environme...

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 a server. Background technique [0002] With the development of communication technology, as a part of mobile communication and personal communication service, location service becomes more and more important. [0003] Fingerprint positioning technology is a commonly used 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. Compare and find matching data to achieve positioning. [0004] During the use of the fingerprint positioning method, due to changes in environmental factors such as crowd movement and obstacles, the signal fingerprint information will be greatly affected. Therefore, when the environment changes, if the fingerprint...
