Research on wireless and composite signal system for high-rise building fire accurate alarm

为有效防控高层建筑火灾事故,利用最新无线通信及复合探测信号技术,设计开发高层建筑火灾精确报警的信号系统。鉴于现有建筑火灾自动报警系统的局限性,重点针对在用高层民用建筑,首先提出一种火灾精确报警的无线烟-温复合式信号系统构建思路;然后通过数据采集终端、分站节点、报警算法等研究,解决系统实现的软硬件问题;最后搭建火灾试验平台,开展系统测试和试验分析。研究表明:所开发系统整体可靠性较好,比其他单一信号系统报警及时、准确,试验中,报警时间可提前2 s以上,误报率小于2%。

In order to effectively prevent and control the high-rise building fire accidents,a signal system was developed for high-rise building fire accurate alarm on the basis of the latest wireless communication and composite signal technology.In view of the limitation of existing building fire auto-alarm systems,before developing the system,a construction idea was put forward for a wireless and composite signal system.Then the hardware and software problems of system implementation were solved through the study of data acquisition terminal,the sub-station node and the alarm algorithm.On this basis,a fire experiment platform was built to test and experiment the system.The research shows that the system has good reliability,can sound the alarm more timely and accurately than other single signal systems,and in the experiment,it trips the alarm over 2 s earlier than other single signal systems do,and the false alarm rate is less than 2%.
