Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts all involve the protection scope of the present invention.

[0040] In this embodiment, a plurality of base stations share a fixed timing source, the timing level of the fixed timing source is 1, each base station is provided with an original timing level and a current timing level, the original timing level is unique, and the original timing level The initial value is equal to the initial value of the current timing level; when the fixed timing source is working normally, base station synchronization is performed as follows:

Abstract

The invention relates to the technical field of communication, and provides a base station synchronization method, a plurality of base stations share one fixed time service source, the time service level of the fixed time service source is 1, each base station is provided with an original time service level and a current time service level, the original time service level is unique, and the current time service level is unique. The initial value of the original time service level is equal to the initial value of the current time service level; when a fixed time service source works normally, base station synchronization is carried out according to the following method: when a first base station receives a data packet sent by the fixed time service source, clock synchronization of the first base station and the fixed time service source is executed, and the current time service level of the first base station is 2; the first base station is any base station in a plurality of base stations. Through the technical scheme, the problem of poor synchronization effect of the base station synchronization method in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a base station synchronization method. Background technique [0002] UWB positioning technology is also called ultra-wideband technology. Compared with traditional narrowband systems, it has the advantages of strong penetrating power, low power consumption, good anti-multipath effect, high security, low system complexity, and accurate positioning. Therefore, UWB technology can be applied to positioning tracking and navigation of indoor and outdoor static or moving objects and people, and can provide very precise positioning accuracy. The realization of UWB positioning requires a terminal to communicate with multiple base stations respectively. The position and distance between base stations can be obtained through surveying and mapping in the early stage of deployment. By calculating the distance between the terminal and each base station, the position of the ...
