语音遥控小车的设计

On Design of Toy-car Controlled with Voice

本系统主要是由51单片机、蓝牙无线模块、电机驱动模块、语音识别模块、显示模块组成的语音遥控小车.它的制作工艺简单且成本不高,语音识别功能相对稳定,而且无线通讯抗干扰能力强.它在识别到人体的语音信息时,把检测到的语音信号转换成电信号,并通过一系列的数据处理转换成简单的数据,然后传输到单片机,单片机通过蓝牙无线传输模块将数据传输给下位机,下位机按照收到的指令做出相应的反应.

This system is to design a toy - car remotely controlled with voice, which mainly consists of 51 sin- gle -chip microcomputer, blue -tooth wireless module, motor drive module, voice recognition module, and dis- play module. Its making process is simple and the cost is not high, speech recognition is relatively stable, and wireless communication anti - jamming ability. In recognition to the human voice messages, the toy - car will con- vert the voice signal into the electrical one, and through a series of data processing into a simple data, and then transmit to the single chip microcomputer, and the single chip computer will, via blue -tooth wireless transmis- sion module, transmit data to the machine, in accordance with the instructions received the machine will react au- tomatically.
