基于单片机PIC16F873的光伏供电系统展示板的设计

在能源需求逐步增大、环境污染持续严重的今天，太阳能的利用已经成为各国争相发展的一个热点，同时，中国政府也一直在加强这一领域科学知识的宣传和普及。为此，设计了一种离线式光伏供电系统展示板，其本身就是一个典型的光伏供电系统，主要包括电源管理、系统控制和系统显示等。文中介绍了展示板系统各个部分的功能和软硬件实现方法。通过太阳辐射量等效为标准太阳辐射强度日照小时数的方法，设计了系统中太阳能电池板和蓄电池容量，最后做出实物。

Design of Exhibiting Board for Solar Power System Based on PIC16F873

Nowadays,with the increasing of energy exhaustion and environment pollution,the utilization of photovoltaic technology has become a hotspot of the whole world.Our government has been reinforcing this field science knowledge propagating and popularization.An off-line exhibiting board for solar power system is designed in this paper,implementation of software and hardware is introduced.By adopting a method of converting radiation of sun to standard radiation intensity sunlight hours,capacity of solar panels and batteries are designed.A sample of the exhibiting board is made,and it works well.
