基于单片机的火灾智能报警设计(附程序代码,接线图,仿真)(任务书,开题报告,论文10000字,程序代码,接线图,仿真)
摘要
当下社会，火灾经常发生，消防安全形势严峻。我们越来越需要一种智能的火灾报警，能够有效减少火灾造成的损失。随着现在人工智能的进步，火灾报警器也在朝着智能化方向发展。科学家也在努力设计更加智能更加安全可靠的火灾报警器。智能火灾报警可以更及时检测到火情，通过及时声光报警通知用户，从而保护了社会和家庭的人身和财产安全。但现阶段一些消防安全保障无法适应社会的进步。例如现阶段火灾等一些违法犯罪案件有增无减,如何解决这个难题,为我们美好舒适的生活创造条件成为了一个研究主题,在现今人们渴望有一个安全温馨的生活空间趋势下,研制一个新型火灾报警系统就极为重要。
本次设计使用STC89C52更为合适，该单片机功能稳定，有很多的输入输出接口。该系统以以51单片机为桥梁，传感器识别有无火灾发生,之后将数据传输给单片机,若无火灾发生,则不报警;若有火灾发生,则驱动蜂鸣器报警、指示灯闪烁。本系统使用较为方便灵活、可靠性极高、火灾情况检测十分准确、迅速、智能。

Abstract
In the society now, fires occurre frequently and the situation of fire safety is very serious. With the advancement of artificial intelligence, fire alarms are also moving toward intelligence.Scientists are also working to design smarter and more reliable fire alarms. Intelligent fire alarm can detect the fire in a more timely manner, through the timely sound and light alarm to inform users, thus protecting the social and family's personal and property safety. But at present some fire safety guarantee can not adapt to the social progress.A fire at the present stage, some illegal crime trend never slow, how to solve this problem, for our good comfortable life create conditions has become a research topic, in today's people were eager to have a safe warm living space, a new type of fire prevention system is extremely important.
This design is more suitable to use STC89C52, the single chip microcomputer function is stable, there are many in and out of the output interface, can timely detect the concentration of smoke gas in the environment. With 51 single-chip microcomputer as the core, control smoke sensor and temperature sensor to identify whether there is no fire.After that, the data is transmitted to the MCU. If there is no fire, the alarm will not alarm; if there is a fire, the buzzer will be driven to alarm and the indicator will flicker. The single-chip microcomputer control smoke sensor and temperature sensor to identify whether there is no fire, The data is then sent to the single-chip microcomputer. If there is no fire, there is no alarm; if a fire occurs, the buzzer is activated.This system is convenient, flexible, reliable, accurate, rapid and intelligent.
