| 摘要在经济飞速发展的现今，随着高楼大厦，地下街道和大型综合性建筑的不断增多，火灾隐患问题慢慢的暴露在人们的视线内。目前的大多传统的火灾预警装置仍是壁挂式或悬顶式节点结构，这种装置通过有线传输的形式将数据发还至控制中心，经过分析判断后响警铃进行报警。但这种方式需要在建筑物墙体内进行线路布设，如果出现墙体内线路老化或是破损，将会浪费大量的人力物力去破开墙体重新布线。 本次设计针对智能家居，楼宇监测等对火灾监控的实际要求，基于ZigBee技术和CC2530设备创新性的设计了以远距离无线通讯传感器节点为基础的无线火灾报警系统。该系统排除了外界环境对线路的影响，提高了火灾报警系统对于火灾预防的有效性和出现异常时的健壮性。21123 经过多次实验证明，系统整体性能良好，能够准确的检测出火焰和可燃气体信号。通过对网络层的检测，也证明了无线火灾报警系统的丢包率和数据传输较为稳定，较之传统有线报警的传统形式有明显优势。 关键词 楼宇监测 灾害防范 火灾预警系统 无线传感器 ZigBee 毕业论文设计说明书（论文）外文摘要 Title The design and implementation of wireless fire alarm system Abstract In the rapid economical development today, with the increasing of high-rise buildings, underground street and large comprehensive buildings, fire hazard problems have gradually exposed in the line of sight of people. Most of the current fire warning devices still use wall-mounted or overhang type node installation, comes in the form of cable transmission data to management control center, and ring through the alarm bell.But this way need to carried out the building wall to accomplish the line layout, if the line which inside wall aging or damaged, it will waste a lot of manpower material resources to break the wall and rewiring. This paper focus on intelligent household, building monitoring actual requirements, design a long-distance wireless sensor node based on ZigBee and wireless sensors in order to improve the effectiveness and robustness of the fire alarm system.. Experiments prove that the node performance is good,can accurately detect the flame and the combustible gas signal. Through to the network layer test, proving that the wireless packet loss rate of fire alarm system and data transmission are also relatively stable, compared with the traditional form, wired alarm has obvious advantages.
