基于单片机的多功能智能小车设计论文一.doc

摘 要 智能作为现代的新发明，是以后的发展方向，他可以按照预先设定的模式在一个环境里自动的运作，不需要人为的管理，可应用于科学勘探等等的用途。智能电动车就是其中的一个体现。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、、Abstract Smart as a modern invention, the direction of development in the future, he can in an environment where automatic operation in accordance with the pre-set pattern, no human management can be applied to the use of scientific exploration. Smart electric car is one of expression. The simplicity of the design of intelligent electric car, using AT89S52 MCU core as the detection and control of the car; metal sensor TL-Q5MC to detect the way the sensor to the iron plates, so that the feedback signal to send to the microcontroller, so that microcontroller in accordance with predetermined operating mode to control the car traveling in the regions according to a predetermined speed, and the operating mode selected by the microcontroller to control the car traveling along the S-shaped iron plates; Hall element A44E detect car speed; using 1602LCD real-time display car traveling car to stop driving, take turns to car travel time, travel distance, average speed and velocity zone traveling time. This design is simple, more easy to implement, but are highly intelligent, humane, to some extent reflects the intelligent.
