摘要
楼宇自动防火报警系统即用一片CPU、可编程并行接口芯片8255A、若干小规模集成电路及烟雾传感器构造一个简单的楼宇防火报警装置,系统根据楼房周围的烟雾浓度自动监控楼房火情,当烟雾浓度达到一定程度,系统报警,当烟雾浓度下降后,系统停止报警。
Design and realization of automatic Fire-Proof and alarm system of building is an simple device based on a CPU,a 8255A,several SSI and a smoke sensor.This system can monitor the building fire case by the density of smoke,it can give an alarm when the smoke density to attain the certain degree, be after the smoke density descend, it stops alarm.
