1、基于80C51智能火灾语音报警系统设计摘要目前,随着电子产品在人类生活中的使用越来越广泛,由此引起的火灾也越来越多,在我们生活得四周到处潜伏着火灾隐患。为了避免火灾以及减少火灾造成的损失,我们必须按照“隐患险于明火,防患胜于救灾,责任重于泰山”的概念设计和完善火灾自动报警系统,将火灾消灭在萌芽状态,最大限度地减少社会财富的损失。本文设计了一种基于单片机8051、集成语音芯片ISD1420、A/D转换器,集成温度传感器AD590和气体传感器TGS202等,利用多传感器信息融合技术,完成语音报警的实用、可靠的单片机语音自动报警系统,着重讲述了该系统的组成形式及工作原理。实践表明,单片机技术在系
2、统报警和其它一些自动控制领域中有着广泛的应用前景。该系统能自动完成对布测点检测,确认火警后能自动报警,并显示火情点,记录火灾发生时间。本系统可安装在各防火单位,它负责不断地向所监视的现场发车巡检信号,监视现场的温度、浓度等,并不断反馈给报警控制器,控制器将接到的信号与内存的正常整定值比较、判断确定火灾。当发生火灾时,可实现语音报警、故障自诊断、浓度显示、报警限设置、延时报警等,是一种结构简单、性能稳定、使用方便、价格低廉、智能化的烟雾传感器,具有一定的实用价值。关键词:火灾报警;单片机;传感器39AbstractNow,withelectronicproductsusedinhumanli
