无线语音遥控智能车资料

无线语音遥控智能车[摘要]20世纪中后叶，随着大规模晶体管集成电路制造工艺的飞速发展，使计算机渗透进城市的血液，成为人类社会生活中密不可分的一部分。越来越多种类的计算机投入社会生产，如果在人们的社会生活中所接触到的计算机均使用不同的、自身特有的人机接口，就要求计算机使用者掌握多种计算机操作语言，这无疑成为人们使用计算机的一大障碍。因此人与计算机的沟通成为了摆在人类面前崭新的课题。在音频压缩处理技术以及无线远程控制技术高速发展的局面下，人们开始考虑使用人类语言作为新的方式和计算机进行无线远程对话。优化人机接口，使计算机智能化，并且能听懂远处传来的人类语言，以人类的方式思考，彻底摆脱复杂的计算机语言和繁琐的输入方式是今后发展的一大方向。台湾凌阳科技推出的16位MCU-DSP混合处理器SPCE061A可以实现上述的语音识别、数据编码等功能，若在其上外扩一nRF2041双工无线模块组成语音遥控器。用一小车模型作为接收机，处理器采用ATMEL公司的高档8位微处理器ATMEGA16L，接收依然使用nRF2401无线模组，便可以使小车接收人类语言的远程控制。在控制者发出向前、向后、向左、向右等语言命令后，遥控器上的凌阳SPCE061A处理器可以自动实现语音辨识，并且与事先训练的语音模型相比较，从而通过nRF2401输出不同的控制命令，模型小车接收到不同的指令后，做出不同的响应动作，这样便可以制作出一个基于无线语音控制的智能小车。今后，根据语音控制机器人的设计理念，可将其移植到诸如汽车，小家电等具有实际意义的产品中去。在人类与计算机的关系日益密切的今天，更为便捷、更为人性化、更为智能化的人机对话方式无疑是今后科技发展的新趋势。[关键词]无线语音遥控小车；凌阳SPCE061A处理器；语音辨识；ATMEGA16L；nRF2401无线模组Wirelessvoiceremotecontrolcar[ABSTRACT]Afterthemiddleofthe20thcenturyleaves,asalarge-scaletransistorintegratedcircuitmanufacturingprocessofrapiddevelopment,computersinfiltrateintothecitiesofblood,humansociallifeareinseparablepart.Computerisgraduallyreplacinghumans,engageincomplex,repetitivecalculationsorlabor.Moreandmoretypesofcomputersintothecommunityproduction,Thecomputerofmoreandmorekindsputsintosocialproduction,ifcomputertouchedusedifferent,one'sowncharacterizedman-machineinterfaceinpeople'ssociallife,requirethecomputerusertograspmanykindsofcomputeroperationlanguage,Thisundoubtedlybecomesagreatobstaclethatpeopleusethecomputer.Sopeopleandcommunicationofthecomputerhavebecomethebrand-newsubjectinfrontofthemankind.Underthecircumstancesthattheaudiofrequencycompressesthesituationofhigh-speeddevelopmentoftreatmenttechnology,peopleconsiderusinghumanlanguageasthenewinteractiveway.Optimizetheman-machineinterface,Makethecomputerintelligentandunderstandthehumanlanguage,thinksinahumanway,itisageneralorientationthatwilldevelopedtogetridofthecomplicatedcomputerlanguageandthetediousinputwayisageneralorientationthatwilldevelopedinthefuture.SPCE061AproducebyLingyangscienceandtechnologyco.,Taiwan.Itcanproformthefunctionthatdescribedabove,enableitscontrolonemodelcar,tomakethecarcanaccepthumancontroloflanguage.Sendsoutforward,backward,towardsleft,towardsrightandsoonthelanguageordersafterthemaster,thecarembarksinsultsthepositiveSPCE061Aprocessortobepossibletoprocessmayrealizethepronunciationidentificationautomatically,andwiththepronunciationmodelwhichtrainsbeforehandcompares,outputcomparisonresultcontrolcardirectcurrentmachinerunningstatus.Fromnowon,accordingtothevoicecontrolrobotdesignidea,mighttransplantittosuchastheautomobile,thesmallhouseholdelectricalappliancesandsoonhasinthepracticalsignificanceproduct.Inhumanandcomputerrelationalclosetoday,moreconvenient,amoreuserfriendly,moreintellectualizedman-machineconversationwaywithoutdoubtwilldaybydaybethenexttechnicaldevelopmentnewtendencyKeyWords：SPCE061AprocessorIntelligentvoicecontrolcar目录0前言...................................................12无线语音遥控智能车设计概述.............................32.1设计目的...........................................................................................................32.2设计实现总体功能...........................................................................................33系统总体方案...........................................43.1方案论证...........................................................................................................43.1.1方案一....................................................................................................43.1.2方案二....................................................................................................53.1.3方案三....................................................................................................53.2方案分析............................................................................................................54芯片的介绍..................................................................................................................63.2.1主控芯片及其各部分性能....................................................................73.2.2SPCE061A用于语音遥控智能小车中的功能.......................................93.3无线语音遥控智能车电机驱动控制方案.....................................................145系统设计方案..........................................144.1系统整体设计方案...........................................................................................154.2主控板设计方案..............................................................................................144.3控制板设计方案..............................................................................................174.4中断方案..........................................................................................................196.声音控制智能小车软件设计..............................196.1语音控制实现流程..........................................................................................196.2语音识别主程序流程......................................................................................216.3语音识别子程序设计.....................................................................................236.3.1训练子程序：........................................................
