题 目 感应式迎宾门铃的设计与制作 学生姓名 学号 所在学院专业班级指导教师 完成地点 年 月 日 电子感应迎宾门铃设计与制作 [摘要]研究本课题的目的是为解决服务性行业“接送” 礼仪智能化的问题，建立一种通用的礼仪服务系统。本设计是基于 AT89C52 单片机制作的感应门铃，采用数码管统计店内现有的人数，运用两个模拟红外光电开关 来识别人体的进出，当有人进入时，进门指示灯闪烁一次，蜂鸣器放出一段优美的音乐，铃声停止后，统计人数的 数码管自动加一。每当有人出去时，出门指示灯闪烁一次，蜂鸣器放出一段优美的音乐，铃声停止后，统计人数的 数码管自动减一。该门铃还可兼作报警器用，晚上把开关调至报警档，当有人进入感应的区域内，即可发出报警声。 本电子迎宾设计电路由单片机控制电路、显示部件、热释电传感检测电路、音乐电路等组成。先由热释电传感判断别人的进出方向，将信号传达给AT89C52单片机，由单片机分析，传达信息给语音电路，让其经过音频放大器发出相应的语音。在微电子技术与数字化技术发展的今天，开发这种服务质量好、智能化程度高、经济实用的自动控制智能迎宾系统，不仅便于统一管理，而且能减少人力资源，还对环境改善、提高经济效益都有着显著的效果。为此设计这种新型的自动电子迎宾器来代替人力是很有必要的。 [关键词]单片机；语音芯片；AT89C52；红外传感；数码管 ；蜂鸣器 The design and manufacture of electronic sensing welcome doorbell Abstract : Research the purpose of this paper is to solve the service industry shuttle etiquette intelligent problem, establish a common etiquette service system. The design Induction doorbell is based on the AT89C52chip production, using digital tube Statistics the number of store. the use of two simulated infrared photoelectric switch keystroke sequence to identify human import, when someone enters, the digital tube automatic plus one, door indicator lights flash once, buzzer play a piece of beautiful music. Whenever someone out, the digital tube automatic minus one, statistical number of digital tube automatic with a flashing light, out of time, the buzzer emits a beautiful piece of music. The doorbell also can be used as alarm , When the night, switch the button to alarm file, When people into the induction area,then sound the alarm. This electronic welcome guests circuit design by single-chip microcomputer control circuit, the power supply circuit, display parts, pyroelectric sensing detection circuit, music circuit etc. First by pyroelectric sensing judging other people access direction, will signal to communicate by microcontroller analysis AT89S52 MicroController Unit, message to voice circuits, let it pass sendsout the corresponding audio amplifier speech.
