| 摘 要： | 利用Actel公司的FPGA设计Endat数据通信接口,实现与绝对值型编码器ECN1313的数据通信.该设计方案以Actel公司的A3P060为硬件设计平台,在LiberoIDEv9.0开发环境中,使用Verilog语言对通信时序进行硬件描述,并采用第三方软件ModelSim6.0进行功能仿真.结果表明,FPGA能够实时获取绝对值编码器的位置值,同时定位精度能够满足多角度偏振辐射计采样角度定位的高精度要求,为仪器探测大气偏振光谱信息提供了保障.

| Abstract: | The communication was implemented with the absolute encoder ECN1313 by Endat interface,which was designed by FPGA of Actel Company.This project was described with Verilog language and simulated in ModelSim6.0,and A3P060 of Actel Company was used as a hardware platform in the LiberoIDE v9.0 development environment.The result indicated that it achieved the high precision requirement of sampling angle positioning for multi-angle polarized radiometer by using the value of the receiving position data and provided a guarantee for the instrument to measure atmospheric polarization spectral information. |
