摘要
随着“信息时代”的到来,作为获取信息的手段——传感器技术得到了显著的进步,其应用领域越来越广泛,对其要求越来越高,需求越来越迫切。传感器技术已成为衡量一个国家科学技术发展水平的重要标志之一。因此,了解并掌握各类传感器的基本结构、工作原理及特性是非常重要的。
为了提高对传感器的认识和了解,尤其是对烟雾传感器的深入研究以及其用法与用途,基于实用、广泛和典型的原则而设计了本系统。本文利用单片机结合传感器技术而开发设计了这一烟雾监控系统。
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,可实现声光报警、故障自诊断、浓度显示、报警限设置、延时报警及与上位机串口通信等,是一种结构简单、性能稳定、使用方便、价格低廉、智能化的自动报警系统,具有一定的实用价值。

Abstract
While “information age” the arrival, obtained the remarkable progress as the gain information method - - sensor technology, its application domain is more and more widespread, is more and more high to its request, the demand is more and more sensor technology has e weighs one of national science and technology level of development important , understood and grasps each kind of sensor the basic structure, the principle of work and the characteristic is extremely important.
In order to enhance to the sensor understanding and the understanding, in particular to the smog sensor thorough research as well as its usage and the use, based on practical, widespread and the model principle has designed this article used the monolithic integrated circuit union sensor technology to develop has designed this smog supervisory system.
The system can be installed in all fire units, which is responsible for continuously monitoring the site to start the inspection signal, monitor the site of temperature, concentration, and continuous feedback to the alarm controller, the controller will receive the signal and the normal memory setting value was determined paring to determine the fire. When fire occurs, can achieve sound and light alarm, fault diagnosis, concentration display, alarm limit settings, delay alarm and munication with the puter is a simple structure, stable performance, easy to use, inexpensive, intelligent automatic fire alarm system, has som
