Abstract

The invention provides a space vector relative parallelism measurement method based on an inertial device. The method comprises the following steps: acquiring a coordinate value of each measured space vector in a navigation coordinate system based on an attitude conversion matrix by using the inertial device; decomposing the coordinate value of each measured space vector in the navigation coordinate system to obtain a corresponding azimuth angle; and calculating the relative parallelism of any two measured space vectors based on the azimuth angle. According to the technical scheme, the technical problems that in the prior art, a measuring method relates to a large number of devices, light is needed to reach, operation is complex, time and labor are wasted, the measuring result precision is low, and repeatability is poor are solved.

Description

technical field [0001] The invention relates to the technical field of inertial measurement, in particular to a method for measuring the relative parallelism of a space vector based on an inertial device. Background technique [0002] There are usually a large number of rollers on the production lines of metal smelting, papermaking, printing and other industries. Taking a steel factory as an example, the production line for manufacturing automobile steel plates has more than 50 large rollers, which are distributed in a 10-story factory building. If they are not parallel, the steel plate will break, resulting in the shutdown of the entire production line and a daily loss of tens of millions of yuan. Therefore, it is necessary to strictly test the relative parallelism between the rollers. At present, the commonly used measurement methods are based on the optical principle, and a reference mirror needs to be installed between the roller shaft and the ground, and a level, a refe...
