基于单片机的语音控制小车-毕业论文

基于单片机的语音控制小车设计摘要随着电子工业的进展，具有语音控制功能的小车越来越受到人们的青睐，在人们的日常消费生活中起着不可忽视的作用。目前，声控技术已在很多领域得到使用。本文对语音控制功能的小车概况做了阐述。在硬件设计方面，本论文以凌阳公司的SPCE061A 单片机为控制核心，以语音小车控制电路板为辅，设计小车的动作。完成了电源电路、复位电路、键盘电路、音频输入电路，音频输出电路和无线控制电路等硬件功能模块的设计。在软件方面，利用 C 语言进行编程，进行语音的“训练”和“识别”。设计出具有如下功能的语音声控小车:能够根据录制的语音命令来控制小车的前进，后退，左转，右转的功能。测试表明，在环境背景噪音不太大，控制者的发音清楚的前提下，语音控制小车的语音识别系统能对特定的语音指令做出智能反应，做出预想中的有限的动作。论文首先对系统的方案进行论证，然后对各单元的软件、硬件工作原理进行了阐述，并介绍了系统的主要组成部分情况。关键词：SPCE061A，语音识别，全桥驱动，小车Voice control car design based on single chip microcomputerAbstractWith the development of the electronics industry, the voice - the control car become more and more popular to people. And it plays an important role in people 's daily life. At present, the voice - activated technology has had 2 in many fields, For example, voice - activated phone. Only if you called out the names you want and it automatically called to the telephone. This article gives a detail to the voice-activated car. In hardware design, the paper use Sunplus SPCE061A as the control of core. On the software, we use C language programming for voice "training"and"recognition". .Completedthepowercircuit,resetcircuit,keyboardcircuitry,audioinputcircuits,audiooutputcircuitandcontrolcircuitofwirelesshardwaresuchasthedesignoffunctionmodules.It has the following features: According to recorded the voice command to control the car to start, stop,turn right , and turn left.
