具有自动跟踪功能的太阳能充放电控制系统

摘要

The STC89C52 SCM-cored solar charging and discharging control system was designed to track sun-light automatically and adopt PWM to control charge and discharge modes simultaneously.In addition, the sys-tem' s control strategy was analyzed and design plan of the main hardware was presented, including ideas rela-ting to software design.Through on-line debugging of the hardware and software, the functions like the auto-tracking, the real-time monitoring of the condition of battery and solar panel and the optimization of charging-discharging frequency can be realized so that purposes of enhancing absorption efficiency of the solar panel and protecting the storage battery can be reached.%以STC89C52单片机为核心,设计了一个太阳能充放电控制系统.该系统能够自动跟踪太阳光,同时采用PWM的方式控制电池的充放电模式.分析了系统的控制策略,给出了系统主要部分的硬件设计图,阐述了系统软件设计思路.通过系统软、硬件联机调试,实现了太阳能电池板自动跟踪太阳光,蓄电池状态的实时监测,太阳能电池板状态的实时监测及蓄电池充放电节奏的优化控制等功能,达到了增强太阳能电池板吸收效率和保护蓄电池的目的.
