摘　　要：设计了一套基于USB2.0接口的便携式地面检测台,包括上位机软件和一台USB通讯适配器,用以模拟卫星平台与星载光谱仪的数据通信。上位机软件提供人机交互界面,适配器完成了星载光谱仪低压差分信号(LVDS)接口数传数据和数管数据对USB接口的通讯转换。实验结果表明:所设计平台可以把光谱仪的LVDS图像数据转换为USB接口数据,并模拟卫星平台数据,可用于对光谱仪进行调试、测试。通讯适配器USB2.0接口的实测速率可达230 Mbps,可将其作为一个模块用于商用光谱仪的通讯接口。A portable ground test platform based on USB2.0 interface including PC software and a USB communication adapter is designed to simulate data communications between satellite platform and satelliteborne spectrometer. The upper computer software offers a human-computer interaction interface. The adapter completes communications between low voltage differential signal（LVDS） data including image transfer data and manage data of satellite-borne spectrometer and USB interface. Experimental results indicate that the designed platform can convert the LVDS image data of spectrometer to USB interface data, and simulate the satellite platform data. It can be used for spectrometer debugging and test. The measured rate of communication adapter USB2.0 interface can reach 230 Mbps, and it can be used as a module to interface commercial spectrometer.
