公交车干粉自动灭火装置的应用 摘要 随着社会的进步，人们越来越重视火灾的防范工作，许多单位或生产线逐渐引入完善的防火系统，目前市场上的防火大多处于原始的人为手动的灭火，其效率低下，效果并不好，因此全新的公交车自动灭火系统这些年也是应用而生，小到家庭的火灾防范，大到整个森林的火灾防范，这都无疑证明自动灭火在当下甚至未来是一个不可阻挡的发展趋势。 2009年6月5日，成都市9路公交车在行驶过程中发生自燃，25名乘客在此次事故中不幸罹难。短短的几分钟，公交车变成了人间炼狱。而在随后的时间里，我国其他地区公交车也发生了类似事故，所幸没有“成都自燃事件”严重。成都公交车自燃事件造也引起有关部门的高度重视，于是，检查公交车上用于应急逃生“救命锤”的配备情况，很快成了各地重视安全工作的一项要事。但是，仅仅配备“救命锤”是远远不够的。因此设计一种适用于汽车发动机舱的公交车自动灭火系统，实现发动机舱火灾的早期快速有效的探测和扑救，对保证司乘人员的生命财产安全具有十分重要和深远的意义。 本课题主要是围绕AT89C51为设计核心的公交车自动灭火系统，通过烟雾和温度传感器采集信号，MCU的控制来实现自动灭火，应用的范围广泛，可扩展性也是相当的强，针对不同的场所可以自行改进相关的部分。本次设计的主要方面是信号的检测和单片机程序的控制部分，也是整个公交车自动灭火系统的两个主要方面。 关键字：公交车灭火装置；单片机；传感器 Application of bus automatic fire extinguishing device Abstract With the progress of the society, people more and more attention to fire prevention work, many unit or product line gradually introduced to improve fire protection system, the fire on the market are mostly in the original manual fire extinguishing, the efficiency is low, the effect is not good, so new bus automatic fire extinguishing system these years is also the application and, small family of fire prevention to the forest fire prevention, it is no doubt that automatic fire extinguishing in the present and even the future is an irresistible trend of development. In June 5, 2009, Chengdu city 9 Bus spontaneous combustion in the process of running, 25 passengers were killed in the accident. Just a few minutes, the bus turned into purgatory. In the subsequent time, the bus in other areas of our country also had a similar accident, but fortunately no serious incidents of spontaneous combustion in Chengdu. Chengdu Bus spontaneous events are also caused by the relevant departments attach great importance to, so check the bus for emergency escape life-saving hammer equipped, soon became a local governments attach importance to the safety of a fish to fry. However, only with the life-saving hammer is far from enough. Therefore design a application in automobile engine cabin of the bus automatic fire extingu
