摘要
传统的陀螺仪动态范围小、精度低、抗冲击能力差,很难达到惯性导航的目的。因此,设计了一种基于线性加速度计(ADXL193)及磁阻传感器(HMC1043)为惯性测量单元的转速及姿态角解算系统。该系统运用FPGA协处理器控制ADC芯片完成12路模拟信号的同步转换,并将转换后的数据缓存;最终由DSP芯片TMS320C6713主处理器完成姿态角及转速的实时解算。
The traditional gyroscope is difficult to achieve the goal of inertial navigation due to its small dynamic range,low precision and poor impact resistance. A mini attitude angle resolving system is designed to detect attitude angle. It takes accelerometer ADXL193 and geomagnetic sensor HMC1043 as MIMU and adopts FPGA as core coprocessor to control the ADC chip to make the 12-way sensor signals converted synchronously,then sampling data cached. Finally,the real-time resolving for attitude angle is achieved by DSP chip which as the core processor.
