说明：  摘 要 　　本系统按要求制作了一个简易智能电动车，它能实现的功能是：从起跑线出发，沿引导线到达 B 点。在此期间检测到铺设在白纸下的薄铁片，并同时发出声光指示信息，实时存储、显示在“直道区”检测到的薄铁片数目。电动车到达 B 点以后进入“弯道区”，沿圆弧引导线到达 C 点，能够检测 C 点下正方形薄铁片，并在 C 点处停车 5 秒，停车期间发出断续的声光信息。之后继续行驶，在光源的引导下，利用超声传感器传来的信号通过障碍区进入停车区并到达车库。最后，电动车完成上述任务后能够立即停车，全程行驶时间小于 90 秒。
(abstract:this systme is about making a simple intelligence electroomobile.the main function:star in the scratch line,along the guide line to point B.during this course,it detectes the thin iror sheet under the blank paper, at the same time it gives out voice and light indicaton message, saves the real-time message,and derects and shows the nombers of the thin iror sheet in the straight district. The electromobile goes into curve district when passing poiont B,and runs,along the camber line to point C. The electromobile can detect the square thin iror sheet under the point C, and stop for 5 seconds.During the pause ,it gives out voice and light message sequencly,then it continues to run .Using light inducting and signal of the ultrasound ,it goes into parking place and garage.At last,electromobile stop immediately after it complmetes the above assignment,it spends less than 90seconds.)
