摘要: 鉴于现有的姿态测量系统具有功耗高、体积大的特点, 以及水下测量平台的姿态通常在海流作用下会发生改变, 由此对平台上所搭载传感器的测量带来极大的影响等问题, 提出了一种采用三轴微加速度和三轴磁阻传感器构成微机电系统(MEMS)组合模块的设计方案, 实现了对水下测量平台俯仰角、横滚角及方向角的实时测量, 从而可实时获取平台姿态信息, 以达到校正传感器输出的目的。试验数据表明, 该系统具有低功耗、体积小、成本低及抗冲击等优点, 能够满足水下平台姿态测量精度。

Abstract: The work of the existing attitude measurement system of the underwater observation platform will be dis-turbed by the ocean wave. Aiming at this problem, a design scheme of micro-electro-mechanical system(MEMS) com-posed of a 3-axis micro acceleration sensor and a 3-axis magneto resistance sensor is given in detail. The system can get pitch, roll and azimuth angles of the underwater observation platform in real-time. Test data show that the system has the advantages of low power consumption, small size, low cost, and shock resistance, and it meets the precision requirement for attitude measurement of the underwater observation platform.
