论文题目 多功能智能小车的设计与制作
(英文) The Design & Fabrication of Multifunctional Intelligent Vehicle
摘 要
智能作为现代社会的新产物，是以后的发展方向，他可以按照预先设定的模式在一个特定的环境里自动的运作，无需人为管理，便可以完成预期所要达到的或是更高的目标。本设计主要体现多功能小车的智能模式，设计中的理论方案、分析方法及特色与创新点等可以为自动运输机器人、采矿勘探机器人、家用自动清洁机器人等自动半自动机器人的设计与普及有一定的参考意义。同时小车可以作为玩具的发展对象，为中国玩具市场技术含量的缺乏进行一定的弥补，实现经济收益，形成商业价值。
整个小车平台主要以51单片机为控制核心，通过无线遥控实现前进后退和转向行驶；通过红外线传感器,实现小车的自适应巡航、避障等功能。
设计采用对比选择，模块独立，综合处理的研究方法。通过翻阅大量的相关文献资料，分析整理出有关信息，在此基础上列出不同的解决方案，结合实际情况对比方案优劣选出最优方案进行设计。
从电机车体，最小系统到无线遥控，红外线对管的自动寻迹再到红外线自动避障和语音控制，完成各模块设计。通过调试检测各模块，得到正确的信号输出，实现其应有的功能。最后将各个调试成功的模块结合到小车的车体上，结合程序，通过单片机的控制，将各模块有效整合在一起，达到所预期的目标，完成最终设计与制作，能使小车在一定的环境中智能化运转。
关键词：智能，红外线传感器，自动寻迹，语音控制，综合处理
Abstract
As a new product of modern society, intelligence is the trend in future development. It can work in some specific environment according to the mode which sets in advance. Dispensing with behavior adjustment management,but it can achieve the expected， even higher goal. The design mainly reflected a smart-car model,The theoretical scheme, analysis method, uniqueness and innovation etc. that pointed in this paper, I think they are will be certain reference value in design and popularity of automatic or semi-automatic robot such as automatic transportation robot, prospecting robot, cleaning household robot etc.. This car can be used as a model of development of toy, to make up the deficiency of technical content in the chinese toy market,to realize economic profit and to form commercial value.
The design takes micro-controller 51 as control center, use wireless control to make car go forward, go backward or turn around; use infrared sensor to achieve the function of adaptive cruise and avoiding barriers.
Using methods of contrast selection, module independence, integrated treatment; consulting a large number of related literature and data; and listing differnet solution; according to practical situation and choose the best scheme to design.
The motor car body, the minimum system and wireless control, the auto-guiding of infrared diode or auto-avioding barriers and voice-control, step by step, the design is forming gradually. And then, debugging and checking every single module, getting the correct signal output. Finally, combining program, conforming every module efficiently to make it work.
