摘要
城市现代化建设步伐越来越快,对城市道路照明及城市亮化工程的要求也更高,2005年全国照明用电达3000亿度,约占全国总用电量的12%左右,节电、节能、绿色照明的要求越来越迫切,国家“十一五规划纲要”明确要求要把节约资源作为国家的基本的国策,节能已成为社会发展的主流。太阳能作为一种“取之不尽,用之不竭”的安全环保的新能源越来越受到重视。同时,随着光伏技术的发展和进步,太阳能路灯的应用已经形成规模。
本课题主要实现用单片机控制太阳能电池对蓄电池的充电管理,控制路灯定时、低照度模式照明。通过GPRS通讯实时采样当前电池电压,放电电流,可以实现远程控制路灯开关。系统主要由太阳能电池、蓄电池、充电控制、照明控制、LED灯、显示模块、GPRS模块、时钟电路和报警电路等部分组成。
关键字:LED照明;GPRS通讯;充电控制
Abstract
Increasingly rapid pace of urban modernization, urban street lighting and city lighting engineering requirements are higher, and the national electricity for lighting in 2005 reached 3000 billion kWh, taking up about 12% of total electricity consumption. Saving electricity, energy conservation and green lighting are more and more urgent, and the National "Eleventh Five-Year Plan" clearly required that we should consider saving resources as the basic policy of a state. Energy conservation has e the mainstream of social development. As one kind of inexhaustible, safe and environmental new energy, solar energy has been paid more and more attention. Meanwhile, with the development and advancement of photovoltaic technology, solar street lamps application has been formed the scale.
This subject mainly realize solar cells with single-chip puter control of battery charging management, control the street lamp timing, low illumination model lighting. Through munication, it can take sample of the current battery voltage and discharge current, and can realize remote control street lamp switch. The system mainly consists of solar battery, the battery, the charging control, lighting control, LED lamps, display module, GPRS module, clocking circuit and alarm circuit and so on.
Key words: LED lighting;munication;charging control
