摘要
针对在现场无人的情况下,可能出现的火灾、盗窃、煤气泄漏等警情设计一个以单片机为控制核心的远程自动报警装置.该装置利用传感器检测警情信息并通过无线收发模块发送给控制器,通过语音模块和DTMF双音频解码电路,能够按优先级预设的手机或座机号码自动循环拨打,在电话接通后利用语音提示实现远程报警,将警情及时准确地告知主人,有效地避免了事故的发生和扩大.
With the improvement of humans living standard and the enhancement of safety consciousness,more attention has been paid to the alarm device gradually.Since the fire,theft,and gas leak would been happened in the situation,and nobody was in,in view of actual application,a remote automatic alarm device had been designed,which was mainly controlled by MCU.Its working process was that an accident signal was detected by a sensor,and sent to the controller by a wireless RF transceiver module,and then automatically and recurrently dialed the mobile or telephone number which was predetermined according to a priority already by the speech module and DTMF tinstone demoding circuit.Then informed the host of the accident after the phone was received.So a remote alarm worked and the accident prevented from happening and expansion effectively and accurately.
