远程家庭安全系统的研究

为保障居民的家庭财产安全,设计了一种远程家庭安全系统。采用以STC单片机为系统核心,通过硬件电路和软件编程设计,可实现对家庭的远程保护。在家中无人情况下,若发生非法入室、意外火灾等突发事件,在单片机的控制下进行现场保护救助,且将电话摘机,由语音芯片将用户号码的DTMF信号送达电话线,实现对用户电话呼叫及远程语音报警,并由电话信号识别芯片进行电话信号识别,以便进行忙音等情况的处理。实验结果表明,设计实现了当意外事件发生时能够及时采取救助措施及对外出用户进行报警通知。

The remote home security system research

A remote home security system to protect the residents of the home and property is designed.Adopted by the STC single chip microcomputer for the core of system,through the design of hardware circuits and software programming,it can be carried out the family’s remote protection.In case of no one at home,if the accident occurred,such like illegal burglary,fire incident and other emergencies,protection and rescue will be implemented under the control of the single chip microcomputer,at the same time the phone is off-hook,the DTMF signal of user number will be serviced to the telephone lines by voice chip,thus achieving remote user phone calls and voice alarm,meanwhile taking signal recognition by the telephone signal recognition chip for handling situations such as busy tone.The Experiment results show that the design achieved to timely relief measures and to alarm to the out users when accidents occurring.
