Abstract

The invention discloses a base station self-calibration method, which includes the following steps: S1, making S base stations P with normal communication conditions inside s The positioning area of ​​is divided into M sub-coordinate systems, and the number of the sub-coordinate systems is set to Scoord i (1≤i≤M); S2. Establish the overall coordinate system Fcoord, which is used to construct the base station coordinates for indoor positioning; S3. In the sub-coordinate system Scoord i (1≤i≤M) is provided with no less than two auxiliary base stations, and the auxiliary base stations are base stations under the known Fcoord coordinates; S4, Scoord i Self-calibration, for every two Scoord i (1≤i≤M) base station P s Perform ranging to calculate base station in Scoord i Coordinates in (1≤i≤M); S5, Fcoord self-calibration, calculate the base station P through the coordinate conversion equation s The overall coordinates; it can measure the coordinates of the base station in a large-scale positioning system, has the accuracy of measurement, and is suitable for a large-scale positioning system.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a base station self-calibration method. Background technique [0002] In indoor positioning, the base station coordinates play a vital role in the positioning effect. At present, in the actual base station deployment, all base station coordinates are mainly obtained by manual measurement. This method is difficult to guarantee the coordinate accuracy and has a large workload. , not suitable for large-scale positioning systems. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a base station self-calibration method, which has the accuracy of base station coordinate measurement and is suitable for large-scale positioning systems. [0004] A kind of technical solution that an embodiment of the present invention solves its technical problem adopts is...
