摘要
针对传统点源式偏振模式检测系统采样速率低、体积大、成本高等问题,提出一种基于ZYNQ7020的高速天空偏振模式检测方案。该方案采用XILINX ZYNQ7020作为控制处理核心,通过RS485总线控制外部高精度编码电机并将高速AD转换芯片3PA1030采集到的高速模拟信号同步写入存储卡中,搭建实验平台并进行了室外填空偏振模式的采集,验证了该系统采集精度高、速率快、便携性强的特点。同时,设备还具有较好的三防特性,可应用于多种天气条件下的天空偏振模式的采集。
Aiming at the problems of low sampling rate,large volume and high cost of traditional point source polarization mode detection system,a high-speed sky polarization mode detection scheme based on ZYNQ7020 is proposed.The solution uses XILINX ZYNQ7020 as the control processing core,controls the external high-precision encoder motor through the RS485 bus,and writes the high-speed analog signals collected by the high-speed AD conversion chip 3PA1030 into the memory card synchronously,builds an experimental platform and conducts outdoor filling in the polarization mode The collection verifies the system’s high collection accuracy,fast speed,and strong portability.At the same time,the equipment also has good three-proof characteristics,which can be applied to the collection of sky polarization modes under various weather conditions.
