基于STC12C5A60S2的点光源自适应控制系统

Adaptive control system of point source based on STC12C5A60S2

本文给出了一种基于单片机的点光源自动跟踪系统设计方案,使用超低功耗的STC12C5A60S2作为整个系统的控制核心,主要由电机驱动模块,点光源检测模块,电源转换模块等组成。利用8路光敏电阻来检测点光源的位置并将检测到的信号经过控制器的运算和处理来确定点光源的运动趋势,并将运算的控制信号控制两台步进电机,使其跟随点光源运动。

This paper presents a point source tracking system design based on a single chip with ultra- low power consumption STC12C5A60S2 as the control core of the system,which is mainly composed of motor drive module,light source detecting module,power conversion modules and other components. The system can detect the position of point light source using photoresistor. The signals detected are operated and processed by the controller to determine the movement trend of the point light source,and the operational control signals are further used to control two stepping motors to make their motion follow the point light source.
