沈阳理工大学学士学位论文摘要智能回收箱作为人类生活中必不可少的清洁工具，伴随着人类走过了每一个时代。随着生活水平的不断提高，人们逐渐对智能回收箱的人性化、智能化提出了更高的要求，因此——智能回收箱应运而生。本设计主要实现基于STC89C52单片机的智能回收箱设计，其主要功能包括自动开关桶盖、温度实时检测、桶内废品装满提示及桶内自动清洗净化功能。设计通过声控及红外传感器实现对信号检测，当探测有效范围内有人进入或声音分贝达到声控开关阈值，经过芯片控制中心模块的分析处理后启动控制电路，打开垃圾桶盖，延时4s（可以调节延时时间）后，自动关闭桶盖；垃圾桶内装有红外对管模块用来检测垃圾是否已满，以便给环卫人员提示；同时本设计具有自动清洗及排污功能，减少垃圾对周围环境的污染，同时清洗后，自动开启桶内排风系统，可快速净化垃圾桶；设计还配有LCD1602液晶显示屏，通过DS18B20温度传感器能实时显示室内的温度。本设计具有自动开关桶盖，自动进出水洗涤内桶，自动排污及净化，实时显示室内温度功能，从而减少卫生感染的隐患，且方便日常生活，并为人们的健康提供有力的保障，为卫生城市和智能城市建设提供一种参考。关键词：STC89C52单片机；步进电机；红外传感器；DS18B20;LCD1602I沈阳理工大学学士学位论文AbstractAstheessentialcleaningtoolinhumanlife,theintelligentrecyclingboxisaccompaniedbythehumanbeingandeverytime..Withthecontinuousimprovementoflivingstandards,peoplegraduallytothesmartrecyclingboxofhumannature,intelligentputforwardhigherrequirements,so-Intelligentrecyclingboxcameintobeing.ThisdesignmainlyrealizesthedesignofsmartbinsbasedonSTC89C52MCU,itsmainfunctionincludesautomaticswitchcover,temperaturereal-timedetection,barrelsofwastefilledwithtipsandbarrelautomaticcleaningfunction.Throughthedesignofsoundandinfraredsensorstoachievesignaldetection,whenthedetectionrangeofpeopleenterorvoicetovoiceswitchthreshold,throughanalyzingandprocessingchipcontrolcentermoduleafterthestartcontrolcircuit,openthebin,delay4S(adjustabledelaytime),automaticclosinglid;garbagebarrelisequippedwithinfraredthecontrolmoduleusedtodetectgarbageisnotfull,soastopromptthesanitationworkers;atthesametimewithautomaticcleaningandblowdownthedesign,reducewastepollutiontothesurroundingenvironment,atthesametimeaftercleaning,automaticopeningbarrelexhaustsystem,rapidpurificationoftrash;designisalsoequippedwithLCD1602LCDscreen,theDS18B20temperaturesensorthereal-timedisplayofindoortemperature.Thisdesignhasautomaticswitchcover,automaticimportandwashinginnerbarrel,automaticblowdownandpurification,real-timedisplayfunctionofindoortemperature,therebyreducingtheriskofinfectioninhealthandconvenientfordailylife,andprovidesthepowerfulsafeguardforthepeople'shealth,thehealthcityandintelligentcityconstructionprovidesareference.Keywords:STC89C52MCU;steppingmotor;infraredsensor;DS18B20;LCD1602LCD目录II沈阳理工大学学士学位论文1绪论........................................................................................................................11.1课题的背景和意义.....................................................................................11.2回收箱的分类和现状...................................................................................21.3智能回收箱的市场前景分析........................................................................31.4设计内容.......................................................................................................32硬件元器件介绍......................................................................................................52....
