1、太阳能LED交通警示板设计摘要木设计采用软硬件结合的方式实现，硬件电路主要包括：充电电路（带充电保护功能）、放电保护电路、传感电路、计数与显示电路、稳压电路、A/D转换电路、太阳能光伏板自动跟踪控制系统七个模块。AT89S52单片机是整个系统的核心部件，通过软件控制多个硬件电路的执行。在编程时根据模块化的设计思路，采用C51语言來编写程序，主要包括：昼夜的判断、片天时通过车辆的计数并用LED动态显示、夜间警示LED闪烁、防瞬时光照、控制电机跟踪、恢复电机到初始位置等模块。设计中实现了口天计数，晚上闪烁，在光控开关控制下，口天开启、晚
2、上关闭的功能，以及防闪电、车灯干扰的功能，并加冇过充、过放保护装置。除上述发挥部分外，又新增两个功能：将太阳能光伏板安装在电机上，口天时通过控制电机旋转來跟踪太阳，充分利用太阳能，对屯池进行充屯；黑夜到來时，将屯机复位到初始状态，第二天重新对太阳进行跟踪。关键字：充电，保护，单片机，计数显示TheLEDSolarTrafficWarningBoardDesignAbstractThisdesignusesthewayrealizationwhichthesoftwareandhardwareunifies,thehardwareel
