基于单片机的太阳能自动跟踪控制系统设计

Design of Solar Energy Automatic Tracking System Based on Single-chip Microcomputer

采用AT89C51单片机搭建控制系统。控制系统包括实时时钟模块、显示模块和光照检测模块等。用预设函数进行太阳角度计算,通过单片机时间控制方式实现自动跟踪,以达到对太阳能电路板的定位,使太阳能电路板始终保持与太阳光垂直,大大提高太阳能的利用率,系统在夜晚、阴天或太阳光幅照度低于工作照度时将自动关机。

The solar energy automatic tracking system adopts SCM（Single-Chip Microcomputer）AT89C51,which is the controlling core of the whole system.The control system is composed of real-time clock module,display module and light detection module,etc.With sun position calculation module,the sun＇s altitude and position are calculated by prescribed function.By using SCM clock control module,the localization of solar panels is achieved.The solar circuit board is always kept perpendicular to the sunlight,which greatly improves the utilization of solar energy.The system will automatically shut down at night.
