捷联惯组的加速度计信号的采集

Data collection of accelerometer for strapdown inertial measurement unit

介绍了加速度计的数据采集方法,采用大规模可编程门阵列(FPGA)实现高精度可编程芯片AD7716的初始化和数据读取,FPGA将所读加速度的数据(包括其他数据)传给DSP,使其在DSP中参与导航解算工作,这里给出了在DSP中所实现的软件流程图．整个设计通过实际运行,证明其有一定的实用价值．

The data collection of an accelerometer is demonstrated in detail. FPGA is adopted to realize the initialization and data collection of the high precision programmable AD7716 chip. The data that FPGA collects is delivered to DSP to carry on navigation computation. Flow chart of the program in DSP is provided. The design is proved to have certain practical values through practical running.
