基于无线传感器网络的火灾现场定位技术研究

Research on Location Technique of Fire Area Based on Wireless Sensor Network

针对目前由消防人员在火灾环境中进行侦察工作的危险性,将无线传感器网络技术应用于消防系统,用具有耐热特性且对温度具有敏感的感知能力的微型传感器在火场中组网,利用DV-hop算法对传感器节点定位,并结合节点处温度变化情况,实现对火场环境的实时监控。经分析得知,基于无线传感器网络的火灾现场定位技术具有很好的可实现性。

Concerning on the fatalness for firemen to reconnoiter in a firing area, the technique of wireless sensor network is applied to fire control system. Subminiature sensors which are heat - resistant and sensitive to temperature are distributed in fire area to constitute wireless networks. With the variety of temperature in nodes, the fire area can be surveilled by locating the sensor nodes using the DV- hop algorithm. After the analysis,the location technique of fire area based on wireless sensor network is realizable.
