Embodiment Construction
[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail based on the drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, but not to limit the present invention.
[0025] Before using the distance adjustment method, the sensing range of each Bluetooth base station is the same, and its sensing distance cannot be adjusted. figure 1 The sensing range of six Bluetooth base stations (A, B, C, D, E, F) is used to cover the entire rectangular area, and the shaded area S can be sensed by the three Bluetooth base stations (A, B, D). As a result, the sensing coverage area is redundant. If users are in this area, they will sense four different base station information at the same time, which will lead to non-unique information extraction. According to the sensing coverage problem see...

The invention provides a method and a system for adjusting sensing distances of Bluetooth base stations. The method includes accurately acquiring coordinate data; computing the maximum sensing radiuses of the various Bluetooth base stations; selecting each two base stations with overlapped cover ranges pairwise when the cover ranges of the Bluetooth base stations are overlapped on each other; computing the distance R between each two corresponding Bluetooth base stations according to coordinates of the two Bluetooth base stations; adjusting the sensing radius of the certain Bluetooth base station of each Bluetooth base station pair so that with the sensing radius of the certain Bluetooth base station with the large cover range is halved; judging whether the half of the corresponding distance R is larger than the sensing radius of the other Bluetooth base station of each Bluetooth base station pair or not and selectively taking a small value of the corresponding distance R and the sensing radius of the other Bluetooth base station as the sensing radius of the other Bluetooth base station. The method and the system have the advantages that the sensing distances can be accurately pertinently adjusted for cover range overlapping conditions according to the coordinates and the sensing radiuses of the various Bluetooth base stations in integral procedures, accordingly, the overlapping conditions of the cover ranges of the various Bluetooth base stations in integral Bluetooth base station application regions can be ultimately precluded, and data interaction service can be accurately and efficiently carried out on various devices in the application regions.
Description
Technical field [0001] The invention relates to the field of Bluetooth technology, in particular to a method and system for adjusting the sensing distance of a Bluetooth base station. Background technique [0002] In recent years, with the widespread use of mobile devices and the increasing popularity of social networks, terminal Bluetooth devices have been widely used. The Bluetooth version has changed from the original V1.1 version to the current V4.0 version. Some mobile phones come with Bluetooth distance sensing. Device, this device only senses two mobile phones with Bluetooth devices. When the distance between the two is too far, Bluetooth will interrupt the connection, not how far the distance is really sensed. [0003] In addition, at present, many public places (such as tourist attractions, museums, exhibition halls) are equipped with Bluetooth base stations. When the Bluetooth positioning method is relatively mature, the Bluetooth base station is sensed while the sensing ...
