Research on Airflow Level Posture Sensor for Restraining Acceleration Interference

提出了一种能够抗加速度干扰的气流式水平姿态传感器。根据气流式倾角敏感元件和气流式倾角敏感元件的输出特点,建立了抗加速度干扰的数学模型;根据抗加速度干扰的数学模型,设计了抗加速度干扰的程序,实现了载体振动、角振动和摇摆等在运动状态下抗加速度干扰的目的,抗加速度干扰能力在95%以上。该传感器不仅能够进行静态倾角测量,而且能够抗动态情况下加速度对摆式倾角传感器的干扰。

An airflow level posture sensor for restraining acceleration interference is described. According to the airflow tilt angle sensitive element and its output feature, a mathematic model on restraining acceleration interference is built. By mathematic modeling and program designing, the acceleration interference in movement status such as carrier vibration, angle vibration and swing is restrained, and the performance increases to more than 95%. The sensor can not only measures the static tilt angle, but restrains the acceleration interference in dynamical status.
