单片机控制信号采集的硬软件设计及其在光源测量系统中的应用

Design of Hardware and Software for Signal Collection with Microcontroller and Its Application in Light Source Test System

该系统目的在于对光源不同波长的光强信号进行采集,进而通过计算获取光源的光谱、色温等参数。介绍了系统的实现方法,包括系统的总体框架,系统的关键软硬件部分的实现;系统主要采用基于微控制器的单板机做主控模块,控制外围电路并连接上位计算机。该系统可以很好地工作于实际产品,并且对于带有步进电机的测量系统具有一定的通用性。

The obiect of this system is to collect light intensity of different wavelength of light source, and obtain parameters of the light source through collected data such as spectrum or color temperature and so on. The methods of realizing this system are introduced; it contains the frame architecture and the key part of both software and hardware. The controlling part of this system is based on microcontroller and takes charge of manipulating electric periphery and exchanging information with computer. This system works well in practical products and it is also suitable for collection system with step motor.
