AI Technical Summary

Technical Problem

The existing inclination sensors measure in dynamic environments incorrectly and cannot perform full-pose inclination angle detection in complex environments.

Method used

Three high-precision quartz accelerometers (X-axis, Y-axis, Z-axis) are used, and the three measurement axes are perpendicular to each other. The X-axis is used for horizontal attitude and lateral inclination measurements. The Y-axis and Z-axis are used to coordinate the pitch angle measurements. The Z-axis has a large inclination angle range and is suitable for horizontal attitude and pitch angle measurements.

Benefits of technology

Accurate measurement of pitch angles and lateral inclination angles in full postures meets the requirements of high accuracy under the most adverse conditions and provides high-resolution measurement results in complex environments.
