多功能智能家居控制器设计

题目：多功能智能家居控制器设计物联网是互联网技术的延伸和扩展，该技术正在被人们所熟知。基于物联网背景，课题着眼于为人们的生活起居，设计了一种多功能智能控制器。控制器分为主机和从机两部分。主机是控制器的主题，控制器提供两种用户输入方式：一种是通过语音识别用户指令，另一种是通过触摸屏输入用户指令。控制器提供两种输出方式：一种为通过TTF液晶显示相关数据，另一种为在出现室内参数异常情况下，通过GSM模块发送紧急通知短信。主控制器通过2.4GHzGFSK无线数据传输方式与从机进行通信，根据通信协议，主机、从机对收到的数据进行解析，得到相关数据。从机的主要功能是接受主机的指令和采集室内数据。从机通过接受主机的指令进行电灯、电视、窗帘等一般性的家居的控制。从机可以采集三类室内参数，一种通过单总线方式直接读取数字量参数，一种通过A/D采集模拟量，第三种是直接通过端口引脚采集开关信号等状态量。系统的数字量采集以DS18B20为代表，模拟量以室内湿度为代表，开关量以燃气泄漏报警信号为代表。控制器初步实现了智能家居语音识别、家电遥控及远程数据通信等基本控制功能，经进一步完善后将具备广泛的市场和应用前景。关键字智能家居；语音控制；无线通信；嵌入式；毕业设计中文摘要 毕业设计外文摘要TitleMultifunctionalSmartHomeControllerAbstractThingsisanextensionandexpansionofInternettechnology,thetechnologyisbeingwellknown.Basedonthebackgroundofthings,topicsfocusonpeople'sdailylife,designedamulti-functionalintelligentcontroller.Thecontrollerisdividedintotwoparts,masterandslave.Isthesubjectofthehostcontroller,theuserinputcontrollerprovidestwoways:oneisausercommandsthroughvoicerecognition,theotherisausercommandinputthroughthetouchscreen.Thecontrollerprovidestwooutputmodes:onefortheliquidcrystaldisplayrelateddatabyTTF,andtheotheroneisintheinteriorparametersappearabnormal,sendemergencynotificationmessagesviaGSMmodule.Themaincontrollervia2.4GHzGFSKwirelessdatatransmissiontocommunicatewiththeslave,accordingtoacommunicationprotocol,host,slavetoresolvethereceiveddatatoobtainrelevantdata.Themainfunctionofthemachineistoacceptahostofcommandsanddataacquisitioninterior.Generalhouseholdslavecontrollights,TV,curtainsandotherhostsbyacceptingcommands.Theslavecancapturethreeindoorparameters,areaddigitalparametersdirectlythroughasinglebusways,oneA/Danalogacquisitionthroughthirdiscollecteddirectlythroughtheportpinstatequantityswitchsignals.DigitalacquisitionsystemwithDS18B20representedanalogtoindoorhumidityrepresented,switchtogasleakalarmsignalisrepresentative.Thecontrollerinitiallyrealizedthesmarthomespeechrecognition,appliancecontrolandremotedatacommunicationsandotherbasiccontrolfunctions,furtherimprovementwillhaveawiderangeofmarketsandapplications.Keywordintelligenthome;voicecontrol;wirelesscommunication;embedded;第Ⅰ页共第Ⅰ页共Ⅰ页目录TOC\o"1-2"\h\u29849第1章绪论 195181.1课题研究背景 1169791.2研究现状分析 页附录1主机程序1#include"led.h"#include"delay.h"#include"key.h"#include"sys.h"#include"lcd.h"#include"usart.h" #include"flash.h"#include"sram.h"#include"malloc.h"#include"string.h"#include"mmc_sd.h"#include"ff.h"#include"exfuns.h"#include"fontupd.h"#include"text.h"#include"piclib.h"#include"string.h"#include"fattester.h"#include"piclib.h"#include"usmart.h"#include"rtc.h"#include"24cxx.h"#include"touch.h"#include"usart2.h" u8host_to_slave[7]={0xff,0x00,0x02,0x1a,0x00,0x01,0xee};//主机发给从机数据电视状态开/关频道1,2,3音量26灯开关窗帘开关u8host_to_slave_buf[7]={0xff,0x00,0x02,0x1a,0x00,0x01,0xee};//主机发给从机数据缓存u8slave_to_host_receive[5]={0xdd,0x16,0x14,0x01,0xcc};//从机发给主机数据温度湿度燃气IntUART2_light,UART2_window,TV_open,TV1,TV2,TV3,VOC1,VOC2,VOC3;//得到path路径下,目标文件的总个数//path:路径//返回值:总有效文件数u16pic_get_tnum(u8*path){ u8res;u16rval=0;DIRtdir;
