新农村太阳能路标与照明控制系统设计摘要社会主义新农村的建设一直是我国乡村发展的重要之事。乡村发展与城市发展有所区别,基础设施是新农村建设发展的重要环节。农村地区人口少、道路不便,很难开展大规模的基础设施建设。以城市常见的路标和照明为例,乡村地区道路复杂,道路里程较短,如果大规模铺设线路往往得不偿失,因此在乡村地区发展太阳能供电,不仅可以解决线路架设问题,后期维护也更加方便。针对于此,本文以STC89C52单片机为核心设计一款太阳能路标和照明的控制系统。太阳能路标与照明系统功能相似,都是利用太阳能转换为电能进行供电,本次研究的主要是控制系统,因此后文都以照明系统为例进行说明与研究。本次设计主要包括充电模块、放电模块、线路保护模块等。通过本次设计可以验证太阳能发电与照明系统的工作过程,可以大范围在农村地区推广使用。关键词:新农村太阳能照明控制系统AbstractThe construction of a new socialist countryside has always been a top priority for ruraldevelopment in China.Rural development is different from urban development,and there areweak links in the construction and development of new rural infrastructure.The smallpopulation and inconvenient roads in rural areas make it difficult to carry out large-scaleinfrastructure construction.Taking common road signs and lighting in cities as an example,rural areas have complex roads and short road mileage,and large-scale laying of lines oftenoutweighs the benefits.Therefore,developing solar power supply in rural areas can not onlysolve the problem of line erection,but also make later maintenance more convenient.Aiming at this,this paper designs a solar energy road sign and lighting control systembased on the STC89C52 microcontroller.This design mainly includes charging module,discharge module,line protection module,etc.This design can verify the working process ofsolar power generation and lighting systems,and can be widely used in rural areas.Key words:New rural solar energy lighting control system.Key words:New rural solar energy lighting control system目录第1章绪论1.1研究背景.…1.2政策现状.21.3课题研究意义..2第2章系统控制方案设计.32.1系统的组成及原理..2.1.1系统的组成32.1.2系统的工作原理.32.2系统控制要求.32.3系统控制方案设计.32.4系统主要硬件选择.42.4.1单片机的选择」2.4.2光敏电阻模块..42.4.3AD转换器52.4.4显示模块的选择.2.4.5L照明灯具选择..6第3章系统硬件电路设计.73.1单片机最小系统电路设计.73.2路标与照明电路设计.73.3光敏电阻电路设计….83.4显示电路设计.83.512V转5V电源电路设计.93.6AD转换电路设计..9第4章系统程序设计.104.1主程序设计…104.2充电子程序设计..104.3放电子程序设计4.4保护子程序.124.5调试与运行.134.5.1实物展示…134.5.2运行效果.13总结..15致谢….1么
