摘要
基于促进学生构建系统性的知识结构,开发了包含手机语音识别模块、蓝牙通信模块、小车控制模块的手机语音远程控制小车案例作为综合课程设计性项目。信息发送端是Android手机客户端——在Eclipse跨平台的自由集成开发环境下开发的语音控制小车apk;信息接收控制端以ATmega32U4芯片为核心单元,利用Arduino IDE开发控制程序,通过DF-Bluetooth蓝牙模块实现通信连接,根据接收的语音命令控制转向显示灯工作,并给不同舵机写不同角度,利用URM37 V3.0超声波传感器检测路面反馈信息,从而控制舵机运动,构成闭合控制系统。试验结果表明:系统能很好地控制小车实现前轮转向并同时伴随转向灯的开启,后轮进退且自主避障,系统性能良好。
To help students build a systematic knowledge structure,we design and develop a speech recognition module in cell-phone to control car remotely. The design contains cell-phone voice recognition module,Bluetooth communication module,car control module. The information sender is Android mobile client where a voice control car apk is developed under free cross-platform integrated development environment based on Eclipse platform. The information receiver and controller are designed by using ATmega32U4 microcontroller chip as a core,control module is programmed on Arduino IDE platform. The communication is via DF-Bluetooth Bluetooth module. Turn lights are implemented,and different angles are realized according to the received voice command control. URM37 V3. 0 ultrasonic sensors is used to detect pavement feedback so as to control servo motion. All parts constitute a closed control system. The results show that： the system can achieve good control of the car＇s front wheel to turn right and left companied by the opening turn signals,rear wheel to back and forth and avoid obstacle autonomously,and has good system performance.
