Analysis of Influencing on the Ground Calibration for PIG Based on Seasons

Abstract:

In order to achieve accurate positioning of the detector in the pipeline, explore the affection of the different seasons and soil moisture on the ground calibration, then ground marking studies by MEMS acoustic vector sensor is proposed. To select four seasons in one year to do comparative experiment, analysis the signals and drawn the angle table. Secondly, we select the most accurate period, to research the impact of the dry soil and wet soil. The results show that: The result of direction on Autumn is the most accurate season, the difference between angle of the measurement point and the true angle can be achieve to 1.051 degrees; On Winter, the relative error is the largest, the orientation angle is the most inaccurate; it is more accurate when the soil is dry than it in wet soil. Far-reaching meaning has been provided in this research.
