基于Android平台的WIFI遥控智能小车的设计

摘要

为了设计一款WIFI遥控智能小车,能够实现在WIFI控制下小车遥控运行、自动跟随、自主循迹、自动避障、视频拍摄和视频回传等功能,提出了基于Android平台的系统总体设计方案,采用了双电源独立供电以避免电机运转引入干扰的供电方案,探讨了直流电机驱动模块的电路设计和抗干扰解决方案,以及WIFI模块的设计方案,并详细介绍了Android设备与单片机之间的通信协议和软件设计的关键模块:电机驱动与PWM调速模块和命令解码模块;测试结果表明:系统运行状态良好,在Android设备控制下小车能够实现遥控运行、自动跟随、自主循迹、自动避障、视频拍摄和视频回传等功能,满足设计要求,达到了预期目标.%In order to design a WIFI remote control intelligent car,which has remote operation,follow,tracking,obstacle avoidance,video capture and video return function through the WIFI control,system overall design scheme on Android platform is proposed.A dual independent power supply is used to avoid the introduction of interference caused by the operation of the motor.The circuit design and anti-jamming solution of the DC motor drive module and the design scheme of the WIFI module are discussed.The communication protocol between the Android device and the microcontroller and the key modules of software design are introduced in detail including motor drive and PWM speed control module,and command decode module.The test results show that the system runs well,and under the control of the Android device,the car can realize the function of remote operation,automatic follow,autonomous tracking,automatic obstacle avoidance,video shooting and video return,to meet the design requirements,to achieve the desired goal.
