Signal Process Technology of Omni-Directional Level Posture

Abstract:

Micro mechanical airflow level posture sensor, combined with micro mechanical skill and air pendulum, the volume is small, the structure is compact, the craft is simple and uniformity of sensitive component is good. But it can be only sensitive to tilt posture around the specific sensitive axle. In order to realize the omni-directional survey, this article utilizes the MEMS tilt-sensitive component to withdraw omni-directional and carries on sensitivity compensation of omni-directional signal. The results show that: resolution is better than 0.1 °; nonlinear is small than 1.2%; range of angle measurement is from 0 °to360 °, realizing survey of omni-directional level measurement.
