摘要
针对采用PGC解调方案的光纤加速度计,提出了一种基于高速数字处理芯片(DSP)的数字检测方案.介绍了DSP系统的软件和硬件的设计及实现.以DSP为核心的数据采集处理系统在光纤加速度计测量系统中得到了很好的应用.系统经过了软件和硬件的调试工作,完成了PGC解调工作.光纤加速度计检测的信号得到了解调,取得了预期目标,这也进一步说明了利用DSP芯片进行数字PGC解调处理方案的可行性.
A digital detection scheme based on highspeed digital signal processor (DSP) was discussed with software and hardware designs of DSP system described. The digital scheme based on DSP achieves PGC demodulation through software and hardware debugging. The signal that the optic fiber accelerometer detected is demodulated and the system achieved its intended purpose.This has proved the feasibility of the scheme, which completes the PGC demodulation by DSP.
