摘  要: 近年來，智能化和自動(dòng)化技術(shù)在玩具制造領(lǐng)域中越來越被關(guān)注。本文介紹了一種基于SPCE061A單片機(jī)的語音遙控小車，重點(diǎn)討論了其硬件子系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)。文章首先介紹了SPCE061A的主要性能及其引腳的功能；接著完成了電源電路、復(fù)位電路、鍵盤電路、音頻輸入電路，音頻輸出電路等硬件功能模塊的設(shè)計(jì)；最后對(duì)制作與調(diào)試過程做了較為詳細(xì)的說明。測(cè)試表明，在環(huán)境背景噪音不太大，控制者發(fā)音清晰的前提下，語音控制小車能對(duì)特定的語音指令作出反應(yīng)，完成指令要求的動(dòng)作。

A Design of Voice Controlled Toy Car Based on SPCE061A MCU
Abstract: Intelligent and automation technology in the toy manufacture have been paid more and more attention in recent years. A design of voice controlled toy car based on SPCE061A MCU (Micro Control Unit) is introduced in this paper. The design and implementation of its hardware subsystem is mainly discussed. Firstly, The SPCE061A's main characters and pins function are introduced. Then design the modulation circuits, such as the power circuit, the reset, the keyboard, the audio input, the audio output, the wireless control circuit and so on. Finally, more detailed explanation to the process of producing and debugging is given. The debugging indicates that, if the background noise is not too big, and the master's pronunciation is clear, this voice controlled car can make the responses to the specific voice commands, finish the commanded movements.
