说明：  本次设计的简易智能电动车，采用AT89S52单片机作为小车的检测和控制核心；采用金属感应器TL-Q5MC来检测路上感应到的铁片，从而把反馈到的信号送单片机，使单片机按照预定的工作模式控制小车在各区域按预定的速度行驶，并且单片机选择的工作模式不同也可控制小车顺着S形铁片行驶；采用霍尔元件A44E检测小车行驶速度；采用1602LCD实时显示小车行驶的时间，小车停止行驶后，轮流显示小车行驶时间、行驶距离、平均速度以及各速度区行驶的时间
(The simple design of the smart electric car, car used as a single-chip AT89S52 detection and control of the core the use of metal detectors to detect TL-Q5MC sensors on the road to the metal plates, thereby sending a signal back to the single-chip, so that single-chip microcomputer according to the mode of control car in the regions according to a predetermined speed, and single-chip mode choice can also be controlled in different cars along the S-shaped metal plates only A44E Hall element used car speed detection 1602LCD using real-time display of the time traveling car, car stop, the rotation time to show the car driving, driving distance, average speed and the speed of travel time zone)
