摘要
为了提高太阳能光伏电池的光电转换效率,本文以单片机为控制核心,设计了室内照明光伏供电控制系统。通过采样光敏电阻检测与比较,双轴机械跟踪定位,使光伏电池组件板与太阳光垂直。系统主要由光敏电阻、A/D转换TLC549芯片、主控单片机STC89C51、舵机转动驱动、液晶显示模块等。系统结构简单、制造成本低,能在人工不干预的情况下自动检测光强度,特别适合与于气候变化和无人看守的情况。
In order to improve the conversion efficiency of photovoltaic cell module, a sunlight automatic tracking system （SATS） was designed using a microcomputer on （MSC） a single chip as a control core in this paper. The orientation of photovoltaic cell module was automatically adjusted to be perpendicular to the rays of sun by checking and comparing the photosensitive resistance using, together with positioning of dual axis mechanical tracking. The system was composed of photosensitive resistance, A/D conversion chip TLC549, STC89C51, steering gear driving and liquid crystal display module. The designed system has many advantages including low cost, simple structure, light intensity checking, no artificial intervention and adaptability for various whether.
