中文摘要：
提出了一种基于USB2．0接口在红外敏感器半实物仿真系统中采用实现数据的实时传输与采集系统的设计方法，设计采用A／D和D／A转换器完成数据的传输与采集．通过FPGA内的SRAM块实现所要传输与采集数据的缓冲存储，利用高速USB2．0接口实现与主机之间的通信接口，并由主机工作站完成对数据的后期处理．该硬件系统作为整个仿真系统中的软件仿真系统和主机数据分析系统之间数据传输通道，具有数据传输高速、准确、实时等特点，满足实时仿真系统的要求．
英文摘要：
A design method of transmission and collection of data based on USB2. 0 interface is presented in HILS system of infrared sensor, which utilize A/D and D/A converter to realize transmission and collection of data. The collected data is buffered and memorized by SRAM block in FPGA, the interface between system and the computer is realized by high speed USB2.0. At last,the data processing is completed in computer The system of hardware has the characteristics of high speed, high precision and real-time, and meet the requirement of simulation system.
