Fire location method based on wireless sensor network

现有的火情监控体系无法准确定位燃火点,预测精度低下,人流量较多的场所火情隐患尤其严重。因此,提出基于无线传感器网络火情定位方法,该火情定位方法由火情探测器、监控端和无线通信系统构成,采用火情探测器中的温度传感器和气象传感器获取火情数据,利用ZigBee无线传感网络将火情数据反馈给监控端,完成火情检测。火情探测器包括阵列传感器模块、信息管理模块和ZigBee无线通信模块,实现火情数据的获取、分析和传输。在软件设计过程中,给出温湿度采集程序的代码,并分析了基于无线传感器网络的火情定位方法,准确定位出火源位置。实验结果表明,所提方法能够准确检测到温度、湿度、烟雾信息,实现火情的准确定位。

Since the available fire monitoring system can＇t locate the fire position accurately, its prediction accuracy is low, and the fire bidden trouble in places with high visitor flow rate is especially serious, the fire positioning method based on wireless sensor network is put forward. This method is composed of the fire detector, monitoring terminal and wireless communi- cation system. The temperature sensor and meteorological sensor in fire detector are used to acquire the fire data, and then the ZigBee wireless sensor network （WSN） is used to feed the fire data back to the monitoring terminal to accomplish the fire detec- tion. The fire detector includes the array sensor module, information management module and ZigBee wireless communication module, which can realize the acquisition, analysis and transmission of fire data. In the process of software design, the code of temperature and humidity acquisition program is given, and the fire location method based on wireless sensor network is ana- lyzed. The fire source position can be located accurately. The experimental results indicate that the method can detect the tem- perature, humidity and smoke information accurately, and realize the accurate fire positioning.
