基于AT89C51的智能公交刷卡系统改进设计与实现
<p>为了适应现代化发展,提高公交管理运输现代化水平,设计了一种基于AT89C51的智能公交刷卡系统。系统以单片机AT89C51作为接口电路与刷卡座信息存储装置,将采集到的收费信息、客流信息、刷卡时间、卡内金额与消费金额等信息显示在LCD显示模块中。在软件部分,增加了系统清算功能与客流信息统计功能,通过系统清算功能可以判断公交卡数据是否处于平衡状态,并将非平衡状态下的用户列入黑名单。通过AT89C
基于单片机的太阳能自动跟踪双轴系统设计
<p>设计了一种基于51单片机的双轴太阳跟踪系统,以提高太阳能的利用效率。该自动控制系统基于51单片机为控制核心的基础上,配合时间、阴晴天检测、光电检测等模块组成,利用阴晴天检测模块判断当前是阴天还是晴天,从而分别调用视日轨迹追踪模式及光电追踪模式。以51单片机为核心,根据太阳的方位角与俯仰角计算出太阳能光伏板的位置转动参数,发出控制指令驱动步进电机模块使双轴机械结构进行转动,使得太阳始终垂直照射
