Abstract
The paper mainly deals with the design of hardware for an automatic fire fighting system, which aimed at closed combustible places. This system adopts single chip microcomputer with smoke sensor and temperature sensor as the detective devices. By
using the single chip microcomputer, it can achieve the aim of automatic fire fighting. And, this system uses high pressured nitrogen as the fire extinguishing agent, which is economical and environment friendly. It accords with the human’s needs of environmental protection.

摘要 本文主要進(jìn)行火災(zāi)自動(dòng)滅火系統(tǒng)的硬件設(shè)計(jì)，主要是針對(duì)封閉式易燃地方。該系統(tǒng)采用單片機(jī)、煙霧傳感器和溫度傳感器作為檢測(cè)器件。通過(guò)使用單片機(jī)，它可以達(dá)到自動(dòng)滅火的目的。此外，本系統(tǒng)采用高壓力氮?dú)庾鳛闇缁饎?，既?jīng)濟(jì)又環(huán)保。它符合人類對(duì)環(huán)境保護(hù)的要求。
