智能远程安防报警系统设计.doc

摘 要 随着社会经济的飞速发展和人民生活水平的不断提高,人们对居住环境的安全性、智能性等方面也提出了更高的要求，智能远程安防报警系统也应运而生，因而大大提高了用户的安全程度，有效保证了居民的人身财产安全。 本文设计了一种智能远程安防报警系统，该系统是以AT89C51单片机作为中央处理器，采用被动式热释电红外线探测器，检测人或某些动物发射的红外线并转化成电信号输出报警，同时还采用烟雾探测器QM-N10，可用于检测火情，当探测器检测到警情信号时通过GPRS给用户发送相应的警情短信，同时系统还具有语音报警、记录和显示报警记录信息等功能。软件采用C语言编写，模块化程序设计；主要包括主程序、显示程序、实时时钟程序和GPRS短信程序等模块。因此该系统可以广泛的应用于仓库、小型商店、无人值守的岗位以及家庭防盗。 本文设计的智能远程安防报警系统具有安装简单、使用方便、体积小、经济实惠、工作稳定、误报率低等特点。 关键词：报警系统；红外线；AT89C51；GPRS Abstract With great improvement of the standard of peoples living, as well as the rapid development and abroad application of microelectronics, the residential Security to people is been more and more important. The security keeping away System of smarthome is emerged as the times required. This paper designs a kind of Intelligent Long Security Alarm System, that system mainly consists of the host that takes AT89C51 Single Chip Microcomputer as the core chip, this system is the use of passive pyroelectric infrared detector. The detector can detect invader who holds up the infrared beam that come from emitter of infrared, Also used smoke detectors QM-N10 can be used to detect fire, send the appropriate police intelligence SMS via GPRS to the user when the probe detects the signal of the police intelligence system also has a voice alarm, record and display the alarm log information and other function. The software is written in assemble language, is designed according to modularization, mostly include the main procedure, display procedure，record sound procedure and voice alarm program, GPRS SMS procedures and modules. So that system can be extensively applied in warehouse, small scaled store, void post and families that guard against theft. This design of the Intelligent Teledata Security Alarm System has these characteristics: easy to install,convenient to use, inexpensive, small, steady-going,and low misinformation rate etc. Key words：alarm system；infrared；AT89C51；GPRS 目 录 第1章 1 1.1 课题研究的背景及意义 1 1.2 安防报警系统的现状 1 1.3 本文的主要工作 2 第2章
