捷联IMU信号采集系统的集成化设计

High-integration design of a signal acquisition system for the trapdown IMU

针对传统的IMU信号采集系统尺寸大、成本高和集成度低等不足,介绍了以DSP为核心的集成式IMU信号采集系统的解决方案,详细阐述了系统硬件实现方案和软件实时误差校正算法。该系统具有速度快、体积小、功耗低等特点。

IN view of the deficiency of a conventional IMU signal acquisition system,such as a big size, high cost and low integration, the paper finds a solution to such a system by taking the DSP chip as a core to be used in the integrated IMU signal acquisition system,and describes how to implement the system hardware and the real-time error-correcting algorithm in the software design. The system is provided with the features of fast speed, small size and low-loss power.
