摘要
结合微惯性测量单元(MIMU)的应用,设计了一种基于ARM微处理器的嵌入式数据采集与处理系统;该系统广泛选用低噪声低功耗芯片,对模拟电路进行信号调理和高速采集;采用高性能工业级ARM微处理器(AT91M55800A),并移植uCOS-II实时操作系统,结合软件算法进行实时数字信号处理;实验结果表明该系统具有体积小、重量轻、功耗低、精度较高、实时性好等优点,非常适合于微小型飞行器、车辆导航等众多军用和民用领域。
A high performance embedded design of MIMU data acquisition and processing system based on ARM was proposed. Low noise and low power waste chips were used abroad in the system, and signal was modulated by the technical analog circuit and collected in high speed. High-performance ARM and uCOS-II was adopted to process digital signal real-lime with system arithmetic. The experimen- tal result indicate that the system has small volume, little weight, low power waste, preferable precision and good real-time ability, and it＇ s very fit for many military and civil field application, such as micro-aircraft and vehicle navigation,
