自动火灾报警系统设计与研究

论述了单片微机火灾报警系统的组成及工作原理。该系统通过火灾探测器采集到信号并且以电压形式传到地址编码器进行变频,再经过A/D转变成数字信号,传输到单片机控制器,启动声光报警显示、电话报警和打印,介绍了可实现通讯传输的报警控制器硬件接口电路和软件的设计及系统实现火灾区域位置报警及故障巡检的功能,该系统探测器采用两线制方式实现多区域报警,减少墙内走线,可靠性提高,便于安装。

Design and Study of Automatic Fire Alarm System

Expounds the composition and operating principle of chip microcomputer-based fire-alarm system.Firstly,the system collects signals and delivers them to the address coder in the form of voltage to convert frequency by fire detector.Then the signals are transformed into digital ones by A/D and delivered to controller to activate acousto-optic alarm display,telephone warning print.The hardware interface circuit design and software design of the alarm controller with function of communication delivery are introduced in the paper.Detectors of this system use two wire system to realize multiregion alarming,which reduces the wall wiring,improves the reliability and eases the installation.
