基于单片机的大型商场火灾报警器的设计思路

Design of MCU based on large shopping mall fire alarm

近几年来,火灾事故频繁发生,这给人们带来了极大的经济损失与生命威胁,特别是在大型商场中,由于人员的相对密集,火灾事故的发生所引起的后果往往是灾难性的。为此,本文提出一种基于STC89C52单片机的火灾报警器,对这种火灾报警器进行了简要的介绍,进而探讨了该火灾报警器的设计思路,在此基础上对该火灾报警器的设计实现及其测试进行了分析,测试结果表明,基于单片机的大型火灾报警器能够通过与传感器等其他配件的使用来进行声光报警,并能够在报警的同时进行自动排烟与灭火,具备极大的应用优势与推广意义。

In recent years,fire accidents occur frequently,which has brought great economic losses and life threatening to people,especially in large shopping malls,due to the relatively dense,the occurrence of fire accidents caused by the consequences could be disastrous.Therefore,this paper proposes a fire alarm system based on STC89C52 MCU,the fire alarm was introduced briefly,and then discusses the design of the fire alarm system,on the basis of the design of the fire alarm implementation and the test are analyzed.The test results show that the large fire alarm can be used by MCU and sensor etc.other parts of the sound and light alarm based on,and be able to automatic smoke and fire alarm at the same time,with the advantages of great significance and promotion.
