摘要
针对小区内安全监控系统可靠性能低的问题,介绍了一种基于双音多频(DTMF)技术的智能小区安全系统与家庭安全子系统。整个系统主要由家庭安全子系统、通信部分、上位机监控等部分组成,主要实现了对家庭安全的监护和小区内安全监控网络系统内的通信。家庭安全子系统以STC89C52单片机为中央处理单元,接收传感器信号和产生报警信号,并将信息传送到小区内总监控室上位机进行实时监控,有效地提高了整个小区的安全性。
Due to the low reliability of safety monitoring system in community,this paper mainly introduces a security system design of intelligent community system and family security subsystem,which is based on dual-tone multifrequency（DTMF）.The whole system mainly includes family security subsystem,communication part and PC monitor.It can achieve the security monitoring of family and communication of the monitoring network system in community.STC89C52 SCM is used as central processing unit,and the system receives the sensor signal,takes alarm response,sends the signal to the PC which is in central control room and realizes real-time monitoring.This system improves the security level of the whole community effectively.
