1、摘 要 I 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。 本文介绍了住宅智能化中的防盗防火报警系统。智能化住宅防盗防火报警系统 集防盗防火功能于一体，可实现自动检测与自动电话拨号报警。自动检测是指由红 外探测与微波探测器构成的双鉴探测器实现盗情检测，同时由温度探测器、光电感 烟探测器和一氧化碳探测器集为一体的复合式火灾探测器完成火情检测。多传感器 的应用实现了低误报率，增强了系统可靠性。自动电话拨号报警是指通过电话网络 自动向相关部门发出语音求救信号。当防盗、防火探测器检测到险情的时候，向单 片机发
2、出中断申请，再由单片机控制电话接口电路，实现模拟摘机，根据险情类 别，自动拨打相关部门的电话号码如小区管理中心电话。本系统通过密码来识别主 人身份，系统开启后只有输入正确的密码才能关闭系统。系统从硬件方面进行了抗 干扰设计，使其具有较好的抗干扰能力，完成系统可靠工作。 关键词：关键词：智能报警系统；防盗防火；自动拨号；语音报警 Abstract II Abstract With the rapid development of communication technique and great improvement of standard of peoples living, the nee
3、d of house has been changed from only the living space to multiform needs of quality, function, service, and so on. A kind of intelligent alarm system for residential area is introduced. It includes the functions of theft-proof and fireproof, performing automatic detection and automatic dial. Pyroel
4、ectric infrared sensor and Microwave sensor combined are used for theft-proof so as to realize automatic detection. Temperature sensor, Photoelectric smoke sensor and CO sensor are integrated to a compound detector for fireproof. Multi-sensors make the least false alarm and enhance the reliability of system. Automatic dial means that it can send help voice through public telephone switch network to the bureau. When the sensor of fireproofing or burglarproof detects any off normal signal, an int
