摘　　要：针对提高太阳电池板光电转换率问题,以MSP430F149单片机为控制核心设计了一种太阳能智能追踪系统。采用光电式跟踪和视日运动轨迹跟踪相结合的方式,通过MSP430F149的ADC12检测采集值判断天气情况,晴天采用光电式跟踪,阴天采用视日运动轨迹跟踪。控制系统通过控制双轴步进电机令太阳电池板转动使其始终垂直于太阳光,从而使太能光的利用率大幅度增加。运行表明,系统运行稳定,节能减排,适用于各种小型太阳电池板充电系统。Aiming at the problem of photovoltaic efficiency, an intelligent solar tracking system was designed with the MSP430F149 MCU as the core. Combination of the photoelectric tracking and trajectory tracking was adopted by the system by sun though the data of ADC12 of MSP430F149 to determine the condition of weather which could photoelectric tracking on sunny and trajectory tracking by cloudy. The solar panels perpendicular was made by the control system to the sunlight all the time though double-axis stepper motor so that utilization rate increased significantly. The running of system show that the system runs stably, energy conservation and emissions reduction.It could be applied to all kinds of small solar panels charge system.
