一种基于DSP的高速角速率陀螺数据采集模块

摘要

Aiming at the MCU can’t acquire multi high speed gyros data at the same time under conditions of multi multiply and divide method floating-point operation, design a high speed angular rate gyros data acquisition module based on DSP. The module combines with gyros data acquisition principle, introduces design method from software and hardware in detail. Based on project application, acquire and deal with certain type photoelectric tracing platform gyros data, give space disturbance angular rate measurement and angular position measurement for stabilizing and controlling circuit. The test result shows that the module can acquire 2 orthogonal high speed gyros data in real time, calculate carrier space angular position in real time, and give high precision angular rate measurement and angular position measurement for stabilizing and controlling circuit.%针对普通单片机在有大量乘除法浮点运算的情况下无法同时采集多个高速陀螺数据的问题，设计了一种基于DSP的高速角速率陀螺数据采集模块。该模块结合陀螺数据采集原理，从软硬件2个方面给出详细的设计方法。并结合工程实际应用，采集处理某光电跟踪平台陀螺仪数据，为稳定控制回路提供空间扰动角速率和角位置测量。实验结果表明：该模块能实时采集2路正交安装的高速陀螺仪数据，实时解算出载体空间角位置，为稳定控制系统提供高精度的角速率和角位置检测。
