文档介绍：简易火灾报警系统摘要我国的火灾自动报警系统经历了从无到有、从简单到复杂的发展过程,其智能化程度也越来越高。目前,国产火灾自动报警系统均采用汉字显示,价格低廉, 适合我国国情,但是火灾自动报警系统由于多数没有分布智能,可靠性低,切产品没有形成系列化,品种不全,产品的外观与较差,编程复杂,调试不方便,设备兼容性差。国外产品多数具有分布智能,可靠性高,产品具有系列化,品种齐全,产品外观美观,人机对话功能强。缺点是多数没有汉化,操作维护不方便,价格较高, 设备兼容性较差。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,可实现现异常报警、故障报警、火灾报警等,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。关键词传感器; 报警器; 单片机; 数据处理 2 SIMPLE FIRE ALARM ABSTRACT China's automatic fire alarm system experience from scratch, from simple plex development process, and its intelligence more and more is also high. At present, the domestic automatic fire alarm system is using Chinese displaying, the price is low, suitable for China's national conditions, but automatic fire alarm system because most no distribution intelligence, low reliability, cut products not form a series, breed plete, product appearance and worse, plex, debugging inconvenient, patibility is poor. foreign product most are distributed intelligence, high reliability, the product has dialogue function is strong,. Defect is most no localization, the operation and maintenance convenience, the price is higher, patibility is poorer. 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 isa simple structure, stable performance, easy to use, inexpensive, intelligent smoke sensor, has some practical value.
