Fire is not only a serious threat to the safety of people's lives and property, but also affects the social stability and development, and accelerated constantly in the process of urbanization, urban population density increasing, under the precondition of building height increases rapidly, threat caused by fire is difficult to assess. The from the control and prevention of fire accidents of based on ZigBee technology proposed a smoke detection fire alarm sensor node design, combined with the corresponding reliability test, demonstrates the feasibility and reliability of the scheme, so that the system can automatically collect smoke signal and send alarm information, and timely on the fire hazard were excluded, to ensure safety.%火灾不仅严重威胁着人们的生命财产安全,更影响着社会的稳定和发展,而在当前城市化进程不断加快,城市人口密度不断增大,建筑高度迅速增加的前提下,火灾所造成的威胁更是难以估量.本文从控制和预防火灾事故的目的出发,基于ZigBee技术,提出了一种烟雾检测火灾报警传感节点的设计方案,同时结合相应的可靠性试验,对方案的可行性和可靠性进行了论证,使得系统能够自动采集烟雾信号,发送报警信息,从而及时对火灾隐患进行排除,确保安全.
