针对目前市场上的智能控制手段,设计出了一款多功能语音控制智能小车的模型。主要采用STC89C52RC单片机作为小车的检测和控制核心,结合红外光电传感器和超声波传感器等组成不同的检测电路,来解决小车在行驶中自动循迹和躲避障碍物等问题,同时采用集成芯片LD3320来实现语音识别,可以让小车完成远距离无线通信功能,最终的测试结果与预先的理论方案一致,能让小车在人的命令下自由移动,达到了预期的功能效果。

Considering the current intelligent control methods in the market,a multi- function voice control intelligent car model is designed. STC89C52 RC MCU,as the core of detection and control of the car,is used together with some infrared photoelectric sensors,ultrasonic sensors and other components to constitute different detection circuits,to address the issues such as automatic tracking and obstacle avoidance of the moving car. By using the integrated chip LD3320 to achieve voice recognition,the car is allowed to realize long- distance wireless communication. The final test result is consistent with the prior theoretical scheme that allows the car to move freely under the command of man,and the desired functionality is achieved.
