摘　　要：系统以MSP430芯片为控制核心,构建了由光敏二极管检测和比较,方位角和高度角双轴机械跟踪定位模块组成的自动控制装置,设计出一套自动指示点光源位置的实时跟踪系统。另外,该系统还能够实现对亮度不同的点光源跟踪,不受日光灯的影响。通过实验验证,系统运行稳定、可靠,跟踪精度在2 cm以内。This design,based on the MSP430 as the control core,builds up a real-time automatic controlling and tracing system which is composed of the detection and comparison of the photosensitive diode,the dual spindle and mechanical trace of azimuth angle and elevating angle.The system can point out the position of the point source of light automatically and immediately.In addition,it can also realize the pinpointing of point light source in different illumination without the influence of the fluorescent light.Through a series of experiments,the system runs stably and reliably with a precision less than 2cm.
