摘　　要：伺服加速度计是测量加速度的传感器件，利用其传感重力加速度的原理可以方便地测量其传感轴方向上的倾角。该文以石英挠性伺服加速度计的理论分析为基础，通过对加速度计在不同角度下的输出电压特性的实验研究与分析，说明利用这种伺服加速度计进行高精度倾角测量是可行的。再应用超低频滤波、16位A/D转换、CPU信号处理等技术，通过汇编程序软件进行数字滤波，可形成一个完整的高精度倾角测量系统。A serve-accelerometer is a kind of sensor for acceleration measuremnent. By using a servo-accelerometer, the measurements of the inclination angle along its sensing axis can be easily got. This paper presents theoretical analysis for a servo-accelerometer with flexible quartz and experimental study of the device output voltages with different inclination angles, which proves that the inclination angle measurements with high accuracy by means of sensing characteristics of the device are very feasible. The servo-accelerometer with flexible quarts, which is connected to a signal processor including the technology of extro-low frequency filtering, 16-bit A/D transformation and CPU controlled by a software, becomes a high accuracy intrument for inclination angle measurements.
