基于超声波的智能语音导盲小车

Intelligent Vehicle Based on Ultrasound and Voice Recognition for the Blind

为了提高电子导盲设备的易操作性,本设计采用三星S3C2440处理器,控制超声波检测前方障碍物。同时,利用红外线检测路面是否平坦。设计中将语音识别技术和语音播放功能应用于人机交互机制,并通过语音指令和陀螺仪控制小车的航向,方便盲人的使用。

In order to improve the electronic guide system to be easy to operate, the design uses Samsung S3C2440 processor to detect the obstacle with the ultrasonic, and uses the infrared to detect whether the pavement is fiat. Speech recognition and voice broadcast are used for human-machine interface. And the direction of the vehicle can be corrected by voice command and gyro- scope. At the end, the design achieves the purpose of flexible application.
