采用国际上标准的UBV星等系统,设计了星模拟器的控制装置,包括硬件设计和软件设计。DSP发出三路PWM脉冲控制卤钨灯的发光亮度,配合三组滤光片构成UBV系统。用DSP控制步进电机的旋转,电机带动变密度盘的旋转控制,实现衰减的自动控制。该装置实现星模拟器的光度和光谱仿真。实验结果表明可以满足设计要求。
Using the international standard UBV system, the star simulator control device is designed, including hardware design and software design. DSP issued three PWM pulse control halogen lamp brightness, with three filters constitute UBV system. With DSP control stepper motor rotation, motor driven variable density disk rotation control, to achieve the attenuation of automatic control. This device realizes the photometric and spectral simulation of star simulator. Experimental results show that the design requirements can be satisfied.
