本文在现有的家庭报警器基础之上,将MODEM芯片引入报警系统,由MODEM(调制解调器)芯片构成的单片机自动报警装置可以借助工厂、企业内部的电话交换机网络,甚至功用电话交换机网络,远距离地传送报警信息,不受地点和时间的限制。真正做到安全、迅速和正确。本文将从硬件设计和软件构成介绍一种单片机控制的智能远程语音报警系统。该系统由用户通过键盘输入十组电话号码作为语音报警对象,预录可长达20S的语音信号说明警情发生的地点,设防状态下即可方便地实现多个设防点的信号检测并迅速进入自动报警状态。
With large scale integrated circuit chip technology and communication technology, the rapid development of security awareness and gradual exaltation, and other peripheral chip microcontroller realization of automatic alarm has become possible, and is a kind of trend. It has not only small volume, convenient installation, complete function, and has advantages of high performance-to-price ratio, so wide application prospect. But the existing market home alarm has some deficiencies in the current products, based on the development of a new automatic alarm, further improve the family of alarm functions, improve its reliability and the practical significance. To ensure the safety of the lives and property of the people, to improve security, fire control, security department of health, quick response ability, has important value.
Based on the existing basis, the family alarm will introduce MODEM chip alarm system, by MODEM (modems) of the chip microcontroller automatic alarm device c
