ZigBee+CC2530无线火灾报警系统设计与实现
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。

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.
