基于Zigbee的高层火灾定位及语音报警系统

Fire Positioning and Voice Alarm System of High-rise Buildings Based on Zigbee

近年来,我国高层建筑火灾发生率呈逐年上升趋势,高层建筑防火和火灾报警的研究,显得尤为迫切和重要,其中火灾报警系统已成为必要的装置,对现代建筑起着极其重要的安全保障作用;提出了一种高层火灾定位及语音报警系统,该系统由Zigbee无线传感器网络、火灾探测器、语音单片机组成;当高层建筑发生火灾时,系统将通过火灾探测器自动判断火灾的发生,然后利用无线传感器网络在第一时间发送给各楼层终端设备,自动触发各楼层语音单片机播报火灾发生的具体楼层和逃生注意事项,可以让人们更快做出反应、选择更合理的逃生方式,为楼内人员的逃生赢得宝贵时间,由此可最大程度地保护人们的生命安全;因此,对高层防火系统的研究可大大降低居民住宅、写字楼、宾馆、饭店等高层建筑的火灾损失。

In recent years, the incidence of high--rise building fire in China is increasing year by year, high--rise building fire and fire a- larm research is particularly urgent and important, in which the fire alarm system has become a necessary device for modern architecture plays an extremely important security role. The paper is to present our design of fire alarm system of high-- rise buildings which is made up of Zig- bee wireless sensor network, fire detector, voice microcomputer. When a high--rise building fires, the system will automatically determine the occurrence of fire, and then sent the message to the terminal of each floor for the first time, automatically trigger the voice MCU to broadcast the concrete firing--floor and escape attention. By this way, it can make people react more quickly choose a more reasonable way to escape, and win valuable time for the escape of the building, which can maximize the protection of people＇ s lives. Therefore, the study of high--rise fire protection system can greatly reduce the damage of residential, office buildings, hotels, restaurants and other high--rise builcling fire damage.
