摘要
随着经济和城市建设的快速发展,城市高层、地下建筑以及大型综合性建筑日益增多,火灾隐患也大大增加,火灾的数量及其造成的损失呈逐年上升趋势。火灾已经成为我国常发性和破坏性以及影响力最强的灾害之一。在工业和民用建筑、宾馆、酒店、图书馆、科研和商业部门,火灾报警系统已成为必要的装置。火灾报警系统对现代建筑起着极其重要的安全保障作用。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。
本系统适合用于家用火灾报警,能实时监视现场的温度,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。在系统组成设计中,对系统采用模块化的功能划分,运用单片机和数字电子技术,按照不同的功能模块进行设计,主要有火灾探测器模块,报警控制器模块,显示模块,键盘控制模块。当发生火灾时,可实现声光报警、故障自诊断、火灾地点显示、报警限设置等,是一种结构简单、性能稳定、使用方便、价格低廉、智能化的温度火灾报警器,具有一定的实用价值。

Abstract
With the rapid development of economy and urban construction, urban high-rise, underground construction and building of large-scale integrated growing number of fire hazards has also greatly increased the number of fire losses caused by increased year by year. The fire has e one of China's often-onset and destructive and the most influential disasters. In industrial and civil buildings, hotels, hotels, libraries, scientific research mercial sectors, fire alarm system has e a necessary device. The fire alarm system of modern architecture plays a vital security role. In order to avoid fires and reduce the losses caused by fire, we must automatically in accordance with the concept of "hidden risks in the fire, precautionary measures better than disaster relief responsibility is extremely heavy," the design and improvement of fire alarm system, fire nipped in the bud, to maximize reduce the loss of social wealth.
This system is suitable for household fire alarm, real-time temperature monitoring site, and continuous feedback to the alarm controller, the controller will receive the signal and the memory setting value to determine to determine the fire. The design of ponents, modular functions into the system, the use of the microcontroller and digital electronic technologies, design according to the different functional modules, a fire de
