针对采矿车深海作业的特殊性,基于航迹推算原理,建立了采矿车位置自测量推算系统。系统中利用三轴数字罗盘、角位移传感器和角位移变速器等,对车体姿态和外部环境进行测量,在所建立的车体运动模型基础上,实现复杂三维地形下颠簸车体坐标原点及地貌探测点真实坐标值推算。该系统能适应复杂工作环境,具有较高定位精度。
Aiming at the peculiarity of deep-sea operation of mining vehicles, a self-measuring and estimating system of mining vehicle position was established based on the principle of track calculation. The system uses the three-axis digital compass, angular displacement sensor and angular displacement transmission to measure the attitude and external environment of the vehicle. Based on the established vehicle body motion model, the coordinate origin and topography of the vehicle body under the complex three-dimensional terrain are realized Detection of the real coordinates of the estimated value. The system can adapt to complex working environment, with high positioning accuracy.
