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 smart electric car, using AT89S52 microcontroller as the core of car inspection and control metal sensors to detect road TL-Q5MC sensitive to the iron, thus bringing the signal to send feedback to the microcontroller, the microcontroller in accordance with a predetermined mode of control car in the regions according to a predetermined speed, and chip select the operating mode can also control the car driving down the S-shaped iron plates using Hall element A44E test car speed using real-time display 1602LCD car travel time , the car stopped moving, the display turns car driving time, distance traveled, average speed and travel time for each speed zone.)
