广州大学松田学院 毕业论文(设计) 题 目基于单片机的自动火灾报警系统设计 火灾自动报警器 摘要:随着经济的发展,人们对防盗、防劫、防火保安设备的需求量大大增加。针对偷盗、抢劫、火灾、煤气泄漏等事故进行检测和报警的系统,其需求也越来越高。 单片机现在已越来越广泛地应用于智能仪表、工业控制、日常生活等很多领域,可以说单片机的应用已渗透到人类的生活、工作的每一个角落,这说明它和我们每个人的工作、生活密切相关,也说明我们每个人都有可能和有机会利用单片机去改造你身边的仪器、产品、工作与生活环境。 Automatic fire alarm Abstract: With economic development, peoples demand for anti-theft, anti-robbery, fire security equipment has greatly increased. For accidents such as theft, robbery, fire, gas leak detection and alarm system, and its demand is increasing. AT89C51 microcontroller, optional integrated temperature sensor the AD590 and gas sensor TGS202 as the sensing element, the use of multi-sensor information fusion technology, developed for small flats fire alarm voice digital networked alarm. SCM now has been more and more widely used in many fields of smart instrumentation, industrial control, daily life, it can be said that the application of SCM has penetrated into human life, in every corner of the work, which shows that it is work, and each of us life is closely related to, and also shows that each of us may have and the opportunity to use a microcontroller to transform you around the instruments, products, work and living environment.
