基于单片机的非特定人语音控制玩具车的设计

提出了一种基于单片机的非特定人语音控制系统,介绍了系统的硬件结构及设计方法.该控制系统以STC12LE5A60S2单片机作为处理器,利用ICRoute公司的LD3320模块进行语音识别,并通过RF905进行无线通信实现对L298N电机驱动模块的控制从而实现了对玩具车行驶的语音控制.该玩具车能够在按键和语音2种方式的控制下实现前进、后退、左转和右转等功能.在车体的前方和两侧各安放1个红外探头,可以实现行驶中自动避障功能.此方案对于智能玩具及相关研究具有较高的价值.

Toy car design of speaker-independent voice control system based on single chip processor

A kind of speaker-independent voice control system based on MCU is advanced in this paper. The hardware structure and design method are introduced. In this system STC12LE5A60S2 was used as the microprocessor and LD3320 as the speech recognition module. The remote controller used the RF905 wireless communication module to control the motor drive module and then achieved to control the toy car driving. This toy car can be under the control in two ways about buttons and voice control to achieve forward, backward, left and right turn, and other functions. In the front and on each side of the car body an infrared sensor was laid on, and it can realize the automatic obstacle avoidance driving function. Because of the trend of the development of intelligent toys and its application, this plan in the research is of high value.
