Embodiment 1

[0046] refer to figure 1 , each independent shape in the figure indicates each independent base station, and different shapes refer to the status of the position calibration of the base station, wherein, the solid circle (●) refers to an unmarked normal base station, and the hollow circle (○) Refers to the calibrated normal base station, the solid triangle (▲) refers to the uncorrected abnormal base station, and the hollow triangle (△) refers to the corrected abnormal base station. Further, with the dotted line in the middle as the dividing line, the left half area is defined as cell A, and the right half area is defined as cell B, and cell A and cell B are adjacent to each other, and there is no overlapping area.

[0047] Taking cell A as an example, the base station positioning method of this application is described in detail.

Embodiment 2

[0091] continue to refer figure 1 , each independent shape in the figure indicates each independent base station, and different shapes refer to the status of the position calibration of the base station, wherein, the solid circle (●) refers to an unmarked normal base station, and the hollow circle (○) Refers to the calibrated normal base station, the solid triangle (▲) refers to the uncorrected abnormal base station, and the hollow triangle (△) refers to the corrected abnormal base station. Further, with the dotted line in the middle as the dividing line, the left half area is defined as cell A, and the right half area is defined as cell B, and cell A and cell B are adjacent to each other, and there is no overlapping area.

[0092] Taking cell A as an example, the base station positioning method of this application is described in detail.

[0093] refer to image 3 , the base station positioning method of the present application includes the following steps:

[0094] S201, ...

Embodiment 3

[0102] continue to refer figure 1 , with the dotted line in the middle as the dividing line, the left half area is defined as cell A, and the right half area is defined as cell B, cell A and cell B are adjacent to each other, and there is no overlapping area. According to the actual situation, the division principle of cell A and cell B tends to be artificial, but it does not rule out the principle based on signal coverage. There are two adjacent and non-overlapping cells, and the non-overlapping cells use this application The technical scheme has more outstanding advantages. Such as figure 1 In the state shown, in the process of confirming the position calibration information one by one by the base stations in the cell A, each base station in the cell B is in an unmarked state, and the base stations 13-17 in the cell B are all uncalibrated normal base stations ( ●).

[0103] For the base station in cell B, its positioning method can choose one of the following methods:

Abstract

The present application provides a base station, a method for locating a base station, and corresponding equipment. The method for locating a base station includes: specifying the current base station as the initial reference base station of the current cell; The position calibration information of the initial reference base station; screening out the corresponding re-measurement base station whose error value is greater than the preset threshold in the position calibration information; receiving the feedback of the re-measurement base station relative to the calibrated base station based on the second ranging strategy position calibration information, and correct the position calibration information of the retested base station. Through the cooperation of the first ranging strategy and the second ranging strategy, the problems of limited positioning accuracy of the base station and complicated positioning calculation methods are overcome, and the base station whose position calibration information error value is greater than the preset threshold can be retested, and the The fusion of the two positioning methods can effectively improve the accuracy of self-calibration between base stations.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, the present application relates to a base station, a method for positioning a base station, and corresponding equipment. Background technique [0002] With the vigorous development of the Internet of Things, people's demand for location services is also increasing, which has given birth to the rapid development of the indoor positioning industry. Among them, UWB technology (Ultra Wideband, ultra-wideband technology), as the technology with the highest precision in the indoor positioning industry, has been widely used. UWB positioning technology mainly completes the position calculation process based on the ranging between the base station and the tag. The premise of the solution is established under the condition that the coordinates of the base station are known. Usually, the base station coordinates are calibrated by a high-precision position calibration in...
