Embodiment Construction

[0021] 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.

[0022] Fingerprint location method of the present invention, as figure 1 shown, including steps:

[0023] Step S101, establish communication and transmit signals between the terminal and each access point, and detect the fingerprint information of the terminal at the current location;

[0024] Step S102, according to the sub-area where the access point currently accessed by the terminal is located and the flow of people in the sub-area, determine the fingerprint database that matches the current location of the terminal, and each of the fingerprint databases stores ...

Abstract

The invention discloses a fingerprint positioning method and server, which divides the positioning coverage area into several sub-areas in advance according to the building pattern, and establishes a fingerprint database according to the fingerprint information of the known position reference points of each sub-area under various traffic conditions. . In the actual positioning process, first determine the matching fingerprint database, then compare the current fingerprint information with the fingerprint information in the determined fingerprint database, select several reference points with the most similar fingerprint information, and perform weighted average on the positions of the selected reference points , as the current location of the terminal to complete the positioning. Since a rich fingerprint library is established according to the architectural pattern and human flow, and the matching fingerprint library is selected for comparison, the influence of building and human flow density on positioning is eliminated, the accuracy of fingerprint positioning is improved, and the environmental protection is improved. applicability.

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 calculates the position of the terminal according to the power of the received signal. [0004] In the process of research and practice, it is found that due to changes in crowds and obstacles, the power of the signal will be greatly affected, and it is difficult to guarantee the accuracy of the positioning results obtained by positioning based on the power. Contents of the invention [0005] Based on the above situation, the present invention proposes a fing...
