The Proposal for Optimalization of Direction of Tilt Measurement in Small Angles

The Proposal for Optimalization of Direction of Tilt Measurement in Small Angles

Paper in proceedings (conference paper)

This work focuses on the measurement of tilt and the tilt direction specifically in small angles. Particularly problematic is the measurement of the tilt direction within tilt angles up to 10°. In such small angles the direction is excessively impacted by noise and it is impossible to measure it precisely. However, in application where the accurate information about it is needed one accelerometer might not be sufficient enough. The method proposed in this paper introduces two accelerometers shifted from each other by 45° counterclockwise in the x and z axes at the same time. The axes of the shifted accelerometer are not affected by the noise as considerably, and therefore the measurement of tilt direction is more accurate. This claim is supported with graphs and measured data. Furthermore, the work includes the introduction of a device designed for this purpose and derivation of needed equations. The proposed optimalization allows to measure tilt from vertical line and its direction relatively easily with enlarged precision. This method can be an alternative to the time-consuming utility programs and complex digital filters which would be otherwise needed in applications concerning precise measurement of the tilt direction. Overall, this is a simple solution that does not bring unwanted additional computational or financial costs.
