多功能遥控小车毕业论文.docx

论文题目：多功能遥控小车 摘要 无线遥控的机器人小车在危险环境作业、人员搜集等应用中可发挥特殊的作用。本次毕业设计选择基于蓝牙遥控的多功能智能小车为对象。设计了该系统的硬件电路原理图和PCB图，控制系统以STC12C5A60S2单片机为主控芯片，采用L293D为电机驱动芯片、蓝牙无线遥控模块、红外光电传感器模块、超声波发射与接收模块等构成外围扩展电路。将自制的控制电路、控制程序和四轮小车机械结构相结合，制作多功能机器人小车。实验调试实现了智能小车的蓝牙无线遥控、自动避障、自动循迹等功能。 关键词:单片机 ；蓝牙遥控 ；PWM调速；光电传感器 Abstract the?robot?wireless remote control?can?play a special role?in the dangerous environment?of operation,?personnel?collection?application.?The graduation design,selection?of multifunctional intelligent vehicle?based on?Bluetooth?remote control?as the object.?The design of hardware circuit?principle?diagram and PCB diagram?of the system,?a control system based on STC12C5A60S2?MCU as the main control?chip,using L293D as the motor?drive chip,?Bluetooth wireless?remote control module,?the infrared photoelectric?sensor module,?ultrasonic transmitter and receiver?modules etc. the?peripheral expansion?circuit.?Combining the?control circuit,?the?control program and?made?four wheel?mechanical structure,?fabrication of multifunctional?robot.?The experimental debugging?Bluetooth?wireless remote control,?smart car?automaticobstacle avoidance,?automatic tracking?and other functions. 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc407801862 毕业设计论文 PAGEREF _Toc407801862 \h 3 HYPERLINK \l _Toc407801863 2.1总体方案设计 PAGEREF _Toc407801863 \h 4 HYPERLINK \l _Toc407801864 2.2无线模块设计 PAGEREF _Toc407801864 \h 5 HYPERLINK \l _Toc407801865 2.3显示模块设计 PAGEREF _Toc407801865 \h 6 HYPERLINK \l _Toc407801866 2.4测速模块设计 PAGEREF _Toc407801866 \h 7 HYPERLINK \l _Toc407801867 2.5调速模块设计 PAGEREF _Toc407801867 \h 9 HYPERLINK \l _Toc407801868 2.6循迹模块设计 PAGEREF _Toc407801868 \h 10 HYPERLINK \l _Toc407801869 2.7避障模块设计 PAGEREF _Toc407801869 \h 11 HYPERLINK \l _Toc407801870 3、 智能车机结构分析 PAGEREF _Toc407801870 \h 11 HYPERLINK \l _Toc407801871 3.1底板设计 PAGEREF _Toc407801871 \h 12 HYPERLINK \l _Toc407801872 3.2 电机与底板的连接支架设计 PAGEREF _Toc407801872 \h 13 HYPERLINK \l _Toc407801873 3.3整体装配图 PAGEREF _Toc407801873 \h 14 HYPERLINK \
