摘　　要：室内火灾报警系统只能基于少量传感器的数据进行判断,容易受到烟雾、温度等干扰,导致误判率较高。为此,基于ZigBee技术和支持向量机设计一种室内火灾自动报警系统。采用传感器节点采集室内烟雾浓度与温度信息,通过ZigBee路由设备将采集的信息转发至ZigBee协调器内。利用基于负载均衡的ZigBee网络多径路由算法建立信息传输路径,将ZigBee路由设备转发的信息传输至支持向量机处理模块内。使用支持向量机算法处理烟雾浓度与温度信息,获取高校室内火灾类型的发生概率,并与事先设置的判别阈值进行比较,当火灾发生概率大于阈值,自动报警模块会自动发出警报。实验结果表明:所设计系统火灾信息采集精度较高,无线网络生存周期长,具备较优的信息传输效果,且能够有效计算高校室内火灾类型发生概率并自动发出警报。The indoor fire alarm system can only make judgments based on a small amount of sensor data,and is susceptible to interference from smoke,temperature,and other factors,leading to an increase in false alarm rates.On this basis,an indoor fire automatic alarm system is designed based on ZigBee technology and support vector machines.The sensor nodes are used to collect indoor smoke concentration and temperature information,and the collected information is forwarded to the ZigBee coordinator by means of ZigBee routing devices.The ZigBee network multipath routing algorithm based on load balancing is used to establish the information transmission path,and the information forwarded by the ZigBee routing device is transmitted into the support vector machine processing module.The support vector machine algorithm is used to process smoke concentration and temperature information to obtain the probability of indoor fire types in universities,and compare it with preset discrimination thresholds.When the probability of fire occurrence exceeds the threshold,the automatic alarm module will automatically issue an alarm.The experimental results show that the designed system has high accuracy in collecting fire information,long wireless network life cycle,excellent information transmission effect,and can effectively calculate the probability of indoor fire types in universities and automatically issue alarms.
