1、课程设计说明书课程设计名称：电子信息工程专业课程设计课程设计题目：基于单片机的无线遥控及避障小车学院名称：信息工程学院专业：电子信息工程班级：100401学号：10041324姓名：童海深评分：教师：陈琼2013年7月3日30电子信息工程专业课程设计任务书2012－2013学年第2学期　第16周－19周题目基于单片机的无线遥控及避障小车内容及要求（1）具有避障、遥控模式可切换的功能（2）遇到障碍物的时候在避障模式小车可以自行避障（3）切换成遥控模式时，可以通过手持把柄进行用户自定义控制，具备前进、后退、左转、右转、停止等基本功能。进度安排：第一周查阅资料，确

2、定方案；注意：学生的设计方案需经指导老师检查通过后方可进实验室进行制作。第二周集中培训；第三周设计制作，软件编程；第四周电路调试，撰写报告。学生姓名：童海深指导时间：第16~19周指导地点：E楼311室任务下达2013年6月10日任务完成2013年7月5日考核方式1.评阅□　2.答辩□3.实际操作□　4.其它□指导教师陈琼系（部）主任贾杰30摘要小车在当今的学生中非常盛行，多出现在可与制作及比赛中。因此本设计采用了无线遥控及避障小车这个课题。小车涉及硬件和软件两部分的设计。硬件上，首先根据课题要求选择合适的车模，为后续工作搭设计基础平台；其次，对车体的机械结

3、构进行了设计与制作，以满足电路板、传感器的安装，美观等要求；最后，对系统的控制电路、驱动电路、传感器电路等各部分电路进行了设计和调试，采用了STC89C52作为系统的控制芯片，其中最主要的技术是利用红外避障传感器对障碍物进行扫描，实现避障和无线遥控的操作，并使用APC220无线模块对小车经行无线控制，诺基亚5110液晶显示行驶状态。软件方面，主要使用了串口通信,IIC总线通信，键盘扫描，定时中断等函数，以保证系统的准确控制。同时，应用差速对方向进行控制，保证车体及时转弯与运行。关键词避障传感器无线模块APC220无线模块履带车模30目录摘要·········
