Positioning system precision measurement method and device and storage medium

Abstract

The invention discloses a positioning system precision measurement method and device and a storage medium. The method comprises the following steps: retrieving a database of a positioning system, and searching reference card positioning information recorded by a base station when a reference card moves to a preset position and a time point when the reference card moves to the preset position; searching test card positioning information recorded by the base station in a preset period where the time point is located from a database, and enabling the positioning card to serve as a test card and move together with the reference card; and obtaining the dynamic precision of the positioning system according to the difference between the positioning distance of the test card and the positioning distance of the reference card. The scheme is suitable for positioning precision measurement of a mining personnel positioning system base station without GPS time service, so that dynamic precision measurement only needs to depend on an internal clock of the base station, and the working difficulty of manual measurement and the difficulty of manual clock calibration are reduced.

Description

technical field [0001] The invention relates to the technical field of positioning measurement, in particular to a positioning system accuracy measurement method, device and storage medium for a mine personnel positioning system, and is mainly suitable for use by safety standard testing centers and third-party testing agencies. Background technique [0002] At present, for the mining personnel positioning system, it is necessary to measure the dynamic accuracy of the system according to the standard requirements of the personnel positioning system. However, the standard does not specify a specific measurement method, so the current measurement method is determined by each testing center. However, existing detection schemes are only applicable to personnel positioning systems with GPS timing, and are not applicable to personnel positioning systems without GPS timing. For example, mine personnel positioning systems basically do not have GPS timing (because there is no GPS in t...

However, existing detection schemes are only applicable to personnel positioning systems with GPS timing, and are not applicable to personnel positioning systems without GPS timing. For example, mine personnel positioning systems basically do not have GPS timing (because there is no GPS in the mine Signal)
