LSM303DLH在钻孔轨迹测量中的应用
|
摘要
针对矿井钻孔轨迹测量的需要,提出了一种基于LSM303DLH集成式传感器的矿用钻孔轨迹测量方法,详细论述了系统总体的结构,硬件电路和软件设计,最后进行了实验室测试和工程实际应用。该芯片集成了三轴加速度传感器和三轴磁传感器,通过对该芯片的控制,计算出钻孔轨迹的2个重要参数,倾角和方位角。结果表明,基于LSM303DLH的钻孔轨迹测量系统在±90°测量范围内,倾角测量绝对误差不大于0.2°,方位角测量绝对误差不超过1.5°,在实际工程应用中,能准确反映钻孔真实轨迹趋势,具有测量精度高、体积小、功耗低等特点,完全满足矿用钻孔轨迹测量需求。
According to the need of borehole trajectory measurement, this paper proposes a mine borehole trajectory measurement method based on LSM303 DLH integrated sensor. The chip integrates a three-axis acceleration sensor and a three-axis magnetic sensor. By controlling the chip, two important parameters of the drilling trajectory, inclination and azimuth are calculated. Studied the principle of drilling trajectory measurement, the overall structure of the system, the hardware circuit and the software design. Finally, laboratory testing and engineering practical applications were carried out. The results show that the LSM303 DLH-based drilling trajectory measurement system is within the plus or minus 90° measurement range, the absolute error of the inclination measurement is not more than 0.2°, and the absolute error of the azimuth measurement is not more than 1.5°. In practical engineering applications, it can accurately reflect the true trajectory trend of the borehole, and has the characteristics of high measurement accuracy, small volume, low power consumption, etc., which fully meets the requirements of mine drilling trajectory measurement.
