智能红外线避障小车毕业论文

Along with the development of science and technology, intelligent and automation technology is more and more popular, all kinds of hi-tech also widely used in intelligent robot toy car and manufacturing field, make intelligent robot more and more diverse. Intelligent car is a variety of high-paying technology integration body, it incorporates mechanical, electronic, sensors, computer hardware, software, artificial intelligence and many other subject knowledge, can involves many of today's current areas of technology. This car design mainly by the single chip microcomputer control system module, manostat module, motor driver module, infrared inspection module and to the wireless digital module composition, system to C8051F340 microcontroller as the core, set to foreign control, use linear regulator chip to voltage stability of control for single chip microcomputer and other peripherals for the reliable power supply, using infrared to the module black and white signal detection, use L298N motor driver module to the dc speed-down motor stability control, use light coupling strength chips for electrical isolation of control, disappear

用红外发射，可以一直发射，也可以间断发射红外线用红外接收管接收信号的高低电平，送到单片机，判断有无障碍，有障碍则执行躲避程序，如左转或右转。

1、如果想学习单片机你可以在网上找一下相关资料很多。

2、如果想快速制作一个红外避障小车并掌握红外避障及其控制原理，可以尝试用精控-定时程序控制器控制器实现。

3、下图是控制器的通用接线原理图。

4、传感器可以采用日本神视CX422反射式红外传感器，检测距离在800mm范围以内，选用NPN晶体管型。

5、将此传感器直接接在控制器输入端，传感器的棕色线接24V电源，蓝色线接地线，黑色线接控制器的一个输入端。

6、转向控制需要分别接到两个输出端，例如：左转接Y1，右转接Y2。

7、控制原理：当传感器检测到有障碍物时向左转，并可设定一定的左转延时时间（例如：秒），当避过障碍物后自动向右转一定的时间（例如：秒），使之继续向原方向前进。

水平有限。红外避障小车采用红外传感器实现前方障碍物检测，并判断障碍物远近。由于时间和水平有限，我们暂选最基本的避障功能作为此次设计的目标。
