【摘要】 传统的水体增氧系统依靠常规电力,耗电量大,因此提出了一种太阳能水体增氧系统。系统由AVR单片机、太阳能电池最大功率点智能跟踪电路、蓄电池充放电电路以及溶解氧检测电路等几部分组成。文中介绍了系统的硬件和软件。实验表明,系统对太阳能电池最大功率点具有良好的跟踪效果,系统运行90 min以后,可以使1.2 m深下层水体与上层水体溶解氧含量基本一致。该系统节能环保、移动方便、可以明显提高水体氧含量,适合于湖泊、鱼池等水体的增氧净化。更多还原

【Abstract】 Traditional water aerator system largely relies on conventional electricity,and requires huge power consumption.Therefore this paper proposes a kind of solar enegy water aerator system,which consists of AVR microcomputer,intelligent tracking circuit of solar maximum power point,battery charge/discharge circuit,and dissolved-oxygen inspection circuit,etc.The hardware and software component of the system design were introduced.Experiment results showed that the system has excellent effect MPPT(maximum power point tracking).Dissolved oxygen of 1.2 m depth bottom and of surface water kept close after 90 min of running.This system was energy saving,environmental friendly,highly mobile,and can effectively rise oxygen content.Thus it was suitable for water oxygenation and purification of lakes,ponds and other water bodies更多还原
