Abstract: A real-time, multi-channel data transmission and acquisition system of Hardware-in-the-loop Simulation system of infrared sensor is presented. The transmitted and collected data is buffered and memorized in SRAM block in FPGA, and USB2.0 interface chip, whose transport speed is high , was used as the interface between system and the PC, at last, data would be treated in PC. The system of hardware has the characteristics of high speed, high precision and real-time, and meet necessaries of simulation system.
