1、 摘要摘要 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。 本课题主要是以 AT89C51 单片机为核心自动灭火系统的设计, 通过烟雾和温度传感器进 行现场信号实时采集,利用单片机控制,当信号大于设定值时,通过蜂鸣器和信号灯发出报 警,同时使继电器驱动喷水装置启动,来实现自动灭火,并通过数码管对采集到的温度进行 显示,利用键盘进
2、行人机通信,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 是整个自动灭火系统的两个主要方面。 关键词关键词:自动灭火系统;AT89C51;烟雾和温度传感器 控制部分 Abstract As society advances, there is growing emphasis on fire prevention work, many units or production lines gradually introducing improved fire protection systems, mo
3、st of the fire protection on the market today still relys on human hand icontrolling , its efficiency is low and original, the effect is not good. Therefore, the new automatic fire extinguishing system apears Naturally. It is really widely used,ranged from home protection to the entire forest fire p
4、revention, which would no doubt prove that automatic fire protection in the future is an irresistible trend. This topic is mainly design with the core around AT89C51 ,aims to creating automatic fire extinguishing system, through the smoke and temperature sensor to collect the signal, MCU control to automatic fire. At the same time,a wide range of applications, scalability is also quite strong, for different places to improve their own related parts. The design of the main aspects contain the s
