摘　　要：介绍了小区家庭安全监控系统.该系统主要通过改进的智能型人体热释电传感器,门磁位移传感器采集报警信息,并通过无线方式予以上传.单片机AT89C55WD控制电话双音频编解码芯片MT8888和语音芯片ISD1420以及ISD1110实现报警.实现了自动电话报警,警笛现场提示,电话远程遥控,紧急求救、在线显示事发地点、相关视频的切换和监控及用户资料显示等功能.该系统适用于小区、工厂等易于集中管理地方的安全防护工作.并给出了系统框图、部分硬件电路图及程序流程图.This thesis introduces a community house security momitor system, which collects alarm signals with the advanced intelligent infrared ray sensor and the magnetic induction sensor. The microcontroller AT89C55WD controls MT8888 DTMF transceiver, voice chip ISD1420 and ISD1110 to give an alarm. The system accomplishes alarming with phone automatically, whistling at the spot, controlling remotely, exigency alarming,switch and supervise video signal relatively and showing information of the alarming location,users＇ information and phone numbers on the computer. It is applicable for a zone or a factory where it is easy to manage and guard intently. We also show the systemic graphs, part of hardware circuit graphs, and program design graphs.
