| 摘 要： | 针对油气井MEMS陀螺定向测斜仪存在的漂移大,精度较低的问题,本文从实际工程应用角度出发,在研究MEMS陀螺仪输出信号漂移特性的基础上,提出了基于最小分辨率的MEMS陀螺漂移抑制方法,利用输出采样的差分值,从MEMS陀螺输出中将传感信号和漂移信号分离,同时通过静态测点对漂移进行估计.实验表明,该方法大幅提高了仪器测量精度,使定向精度提高50％以上,同时该方法为其它类似传感器漂移抑制提供了一种有益的参考.

| Abstract: | Aiming at the disadvantages of micro electro mechanical systems(MEMS) gyroscope directional inclinometers in oil and gas well directional measurement,this paper presents a method of decreasing the drift of MEMS gyroscope based on minimum resolution.On the basis of studying the drift characteristics of the MEMS gyroscope output signal,the new method utilizes the sampling difference value to separate valid signal from drift signal in MEMS gyroscope output and estimates the drift with static experiments to sup... |
