1 序言
火災自動報警控制系統(tǒng)經(jīng)歷了一個過程，從簡單到復雜和情報系統(tǒng)在中國越來越多。其特點是自動火災探測報警技術(shù)，隨著計算機和檢測技術(shù)的發(fā)展有很大的進步。目前，火災自動報警控制系統(tǒng)采用大容量的抽水蓄能電站，商場，高層辦公樓，酒店和其他地方。他們被用在一些更高層次的總線型報警控制系統(tǒng)，智能報警控制方法的一個區(qū)域集中的集合，在一些居民區(qū)和商業(yè)樓宇安裝了由單一的火災自動報警檢測裝置。這些檢測報警裝置，有時失敗報告，或誤傳。它的可靠性不高，因為使用單一傳感器。因此，需要開發(fā)具有結(jié)構(gòu)簡單，成本低，可靠性高，響應快的火災自動檢測系統(tǒng)。
2 該系統(tǒng)的一般項目
硬件框圖如圖1所示，由溫度傳感器，煙霧傳感器，信號處理模塊，MCU模塊和自動報警模塊的硬件。非電氣量，是通過傳感元件傳感器（煙霧傳感器和
成電信號，信號處理以及信號轉(zhuǎn)換成模擬量，數(shù)字量，溫度傳感器）將現(xiàn)場溫度，煙霧等非電信號。最后，對采樣數(shù)據(jù)進行處理，并與單片機系統(tǒng)的限制。該系統(tǒng)可以產(chǎn)生本地和遠程自動報警信號。

Abstract: The paper introduced an automatic warehouse fire a1arm system based on MCU. The system was mainly made up of ATmega16, temperature sensors, smoke sensors, and EX-1 auto dialed alarm module. In the system, temperature signals were transformed to serial data, and smoke signals were transformed to voltage signals. All the data were processed by MCU. When the surveillance system checked fire in warehouse, alarm signal was turn on, meanwhile the messages were transmitted to managers through EX-1. Application of the system was convenient to deal with fire in-time, efficiently by warehouse manager.

I. INTRODUCTION
Automatic fire alarm control system has experienced a process from the simple to the complex and intelligence system increasingly in China. The characteristic is automatic fire detection and alarm technology has a great progress along with computing and detection technology development. At present, automatic fire alarm control system was used in bulk storage plant, shopping malls, high-level office buildings, hotels and other places. They were used in a number of collections focused on one area of intelligent alarm control method with higher levels of bus-type alarm control system, and in some residential areas and commercial buildings were installed by a single automatic
