摘要
主要针对捷联惯导系统中对加速度计信息处理的高精度要求,介绍了基于高精度A/D的对石英挠性加速度计数据进行采集的设计,完成了系统的软、硬件设计。设计采用了高精度A/D转换芯片AD7691和FPGA芯片XC3S500E来完成系统功能,在详细阐述硬件设计的基础上,对软件设计进行了相应的介绍。
To achieve the high-precision requirement of a accelerometer＇ s information processing in SNS, a design of collecting quartz-flexibility-accelerator＇ s data based on high-precision A/D and FPGA was proposed. The design of hardware and software for the system was put forward. High-precision A/D chip AD7691 and FPGA chip XC3S500E were adopted to fulfill the system function. The design of software is presented based on representation of design of hardware in detail.
