基于火灾报警和被困人员定位功能的消防系统设计

Design of fire fighting system based on fire alarm and trapped personnel location function

我国目前有线火灾报警系统较成熟,但并不具备被困人员定位追踪功能,无线报警系统正在兴起。针对这一现状,文章设计了一种具有火灾报警和被困人员定位功能的消防系统。该系统包括参考节点、定位节点及网关,火灾发生时,定位节点能与参考节点通过Zig Bee进行无线通信,并计算出自身位置发送至网关,网关通过CAN总线将信息汇总到控制中心。从而实现了无线火灾报警和被困人员定位,在实施救援时,能够大大降低救援难度,缩短救援时间。

At present, the wired fire alarm system in China is mature, but it does not have the function of locating and tracking trapped persons. And the wireless alarm system is on the rise. In view of this situation, this paper designs a kind of fire fighting system with the function of fire alarm and trapped personnel location. The system includes a reference node, a location node and a gateway. When a fire occurs, the location node can communicate wirelessly with the reference node through Zig Bee, and calculate its own position to send to the gateway. The gateway aggregates the information to the control center through the CAN bus. Thus, the wireless fire alarm and the location of trapped personnel can be realized, and the rescue difficulties can be greatly reduced when the rescue is carried out. To shorten the rescue time.
