摘　　要：为满足星模拟器多色温、大星等范围的要求,设计了一种新型的单星模拟系统。该系统采用多束不同窄带光谱、不同强度的光线混合,控制总体输出光强,最终实现不同等效黑体色温和不同星等。通过RS-485串行总线对系统进行总体控制,也可对各个模块进行独立控制,完善的人机接口,方便人机交互。现场实验表明:该系统稳定可靠,调节灵活,能有效满足测试需求。In order to meet the star simulator＇s requirements of multi-color-temperature and wide range of magnitude, a new system was proposed for the simulator. A variety of rays with different narrow-band spectra and different intensities are mixed in the system. Thus the overall output of light intensity can be controlled to achieve different equivalent blackbody temperatures and different magnitudes eventually. Both the current system and each module are controlled by the RS-485 serial bus. And convenient man-machine interface provides human-computer interaction. The experiment results has manifested that the system owns high stability, reliability and the flexibility of adjustment. The design can satisfy the testing demands.
