1、摘要本文设计的家庭智能化中的防盗报警系统。智能化防盗报警系统集防盗功能于一体，可全天候自动检测盗普，当确定普情吋自动通过电话报普。传感器采用热释电红外传感器，对盗情进行检测，当有人闯入时，微波探测器检测到盗情，然后向单片机发出屮断申请，单片机控制电话拨号电路，模拟摘机，向相关部门发出语咅求救信号。本系统以单片机89C51为核心，配以各种功能模块，来满足人们门常生活屮的安全需求，木系统采用Y热释电红外传感器，它的制作简申、成木低，安装比较方便，而且防盗性能比较稳定，抗干扰力强、灵敏度高，这种防盗器安装隐

2、蔽，不易被发觉。同时它的信号经过单片机系统处理后方便和PC机通信，便于多用户统一管理。木设计包括硬件和软件设计两个部分。硬件部分包括红外探测电路、LED控制电路、声光报警电路及单片机控制电路等。自动检测功能由红外探测电路实现，当有盗贼穿过此装置吋，红外传感器立即将检测到的信号经过信号处理后传送给主机电路，由主机来判断信号并驱动电路报警。报警功能由扬声器、蜂鸣器等发声装置实现，同时通过RS-485通信报警给小区警卫。本设计通过红外传感器探测人体红外线信号，从而达到报警的功能，满足了人们曰常生活对防盗报警
