摘要
采用三轴正交加速度传感器测量地球重力矢量和三轴正交磁强传感器测量地磁场矢量的测斜原理,推导出了倾斜角、方位角和工具面角的计算公式;从硬件和软件两方面对智能测斜仪进行了研究和误差分析,并对主要的误差源作了软件补偿;采用Delphi语言作为软件平台,利用多线程开发了地面监控程序。
The inclinometer theories of earth gravity vector measured by three-axis orthogonal accelerometers and earth magnetic vector measured by three-axis orthogonal magnetic sensors were introduced. Based on these theories; the calculation methods of rake angle, azimuth and tool angle were deduced. The intelligent inclinometer was investigated from hardware aspect and software aspect separately, its error was analyzed, and the main errors were compensated by the software. The ground monitor system was designed through using multithreading technology and employing Delphi as the software platform.
