摘要
随着化石能源的日益短缺以及人们环保意识的不断加强,光伏发电技术倍受关注。针对当前太阳能路灯能源利用率低且无法实现连续阴雨天的正常工作的问题,本文对太阳能路灯控制器进行了改进,设计了基于单片机89LPC936的市电互补控制器。该控制器将蓄电池供电与市电供电相结合,在最大程度利用太阳能的基础上,将市电作为备用电源,不仅解决了阴雨天的供电问题,而且节约了化石能源。实验结果表明,该控制器在蓄电池电量不足的情况下实现蓄电池供电与市电供电的自动切换,从而防止了蓄电池的过放电。
With the growing shortage of fossil fuels and the strengthening of environmental protection awareness of people,photovoltaic generation technology is getting more and more attention.The current solar street lamp,which energy utilization rate is very low,can＇t work formally in continuous rainy days,for the problem,the paper has improved the controller of the solar street lamp and designed a city power complementary controller based on the 89LPC936 MCU.The controllor combined battery-power supply with electricity supply,that is maximizing the usage of solar energy and taking the city-powered as backup power supply.This controller not only can solve the problem of power supply,but also save fossil fuels.Experiment results showed that the controller will switch between battery power and city power automatically in the absence of sufficient battery power,in order to prevent over discharge of battery.
