毕业设计（论文）--基于AT89S51单片机生人入侵自动拨号报警系统设计.doc

摘 要 随着信息技术的飞速发展以及人们生活水平的大幅度提高，人们对住宅的需求已从追求简单的生存空间向着追求质量、功能、服务等多重需求过渡。 本文设计了住宅智能化中的防盗报警系统。该系统主要由自动检测与自动电话拨号报警两部分组成。自动检测是指通过热释电红外探测器感应人体发出的红外线进行盗情检测。自动电话拨号报警是指由单片机，自动拨号芯片，语音芯片以及电话网络构成的系统通过对感应信号的处理自动向用户和相关部门发出语音求救信号。 本系统通过设计密码键盘来识别主人身份，该系统同时具有现场声光报警和记录盗情发生时间的功能。该系统以单片机控制技术，传感器技术和自动拨号技术为基础，单片机AT89S51，自动拨号芯片，语音芯片为基本器件。通过对输入传感器信号的判断，处理，驱动相关模块，实现报警，记录，显示等功能。用热释电红外传感器模块感应监测一定范围内的移动人体，以输入报警信号，用蜂鸣器模拟声音报警，用发光二极管模拟光报警，用LCD1602液晶显示模块显示相关数据。该报警系统具有一定的智能防盗报警功能，可以基本满足住宅的智能安防要求，在人们日益追求住宅安全、舒适、经济的今天具有广泛的应用前景。 关键词：智能报警系统；防盗；自动拨号；语音报警；热释电红外传感器 Abstract With the rapid development of information technology and the increase of peoples living standard, people’s residential needs from the pursuit of simple living space to pursue quality, function and service etc. The paper designs the residential intelligent alarming system. The system is mainly composed by two parts of automatic detection and automatic telephone dialing alarm. The automatic detection means pyroelectric infrared sensors detect the pirates of the situation through inducing IR issued by the human body. Automatic telephone dialing alarm means that the system which consists of the MCU, automatically dial chip, voice chip and telephone network automatically sent to the user and the relevant departments voice distress signal through processing the sensor’s signal. The system through the password to identify the status of the host, this system also has the on-site sound-light alarm and record the time feeling of theft. This system with single-chip microcomputer control technology, AT89S51 single-chip, dial-up chip, pronunciation chip for basic components, through to the input sensor signal processing, the judge, driven, alarm, record module, display function. Pyroelectric sensor module with a sensor to monitor movement within the human body, to enter the alarm signal, alarm with a buzzer to sound, with light-emitting diode light alarm, with the LCD1602 display data. The alarm system has some intelligent burglar alarm, can basic
