自动往返电动小汽车设计报告

Design Report of The Electric Self-motioncar

本设计以单片机AT89C5 1为核心组成测控系统 ,利用红外线发射与检测技术对电动小汽车的运行状态跟踪检测 ;由单片机对汽车的运行姿态实时作出反应 ,并输出相适应的控制指令 ,由驱动执行电路完成限速行驶、全速前进、定点定时停车和自动返回等基本操作以及紧急避险、自动导航、发车令牌控制等功能 ;对小车运行时间、距离等参数进行直观显示 .电路采取了多种抗干扰措施 ,工作稳定可靠 .整个系统按要求安装于车体上实施跟踪监控 .

Servomechanism of the design is based on SCM AT89C51.Movement of the car is detected by means of infrared radiation and measure.The function Real-time response,corrsponding signal out-put is administered by the SCM.Speed restriction,stop timing and automatic return is controlled by the drive adminoster cvreuit.It can execute the function emergency harard escape Automeatic navigatvon and start off order control,too.Time of play and distance is displayed immediately.Resort of auto-jamming being used,the system is credible.The whole system is installed in the car to watch and control.
