The paper deals with a Wireless Sensor Network (WSN) as a reliable solution for capturing the kinematics of a fire front spreading over a fuel bed. To provide reliable information in fire studies and support fire fighting strategies, a Wireless Sensor Network must be able to perform three sequential actions: 1) sensing thermal data in the open as the gas temperature; 2) detecting a fire i.e., the spatial position of a flame; 3) tracking the fire spread during its spatial and temporal evolution. One of the great challenges in performing fire front tracking with a WSN is to avoid the destruction of motes by the fire. This paper therefore shows the performance of Wireless Sensor Network when the motes are protected with a thermal insulation dedicated to track a fire spreading across vegetative fuels on a field scale. The resulting experimental WSN is then used in series of wildfire experiments performed in the open in vegetation areas ranging in size from 50 to 1,000 m(2).
本文探讨了无线传感器网络（WSN）作为一种可靠的解决方案，用于捕获在燃料床上方蔓延的火前线的运动学。为了在火灾研究中提供可靠的信息并支持火灾扑救策略，无线传感器网络必须能够执行三个连续的动作：1）在开放区域中感测热数据，例如气体温度；2）检测火灾，即火焰的空间位置；3）跟踪火灾在其时空演变过程中的蔓延。使用 WSN 进行火前线跟踪的一个巨大挑战是避免火灾对传感器节点的破坏。因此，本文展示了在使用专门用于跟踪跨越野外植被燃料的火灾的热绝缘材料保护传感器节点时，无线传感器网络的性能。然后，在大小从 50 到 1000 平方米不等的开放植被区域中进行了一系列野外火灾实验，使用所得到的实验性 WSN 进行了这些实验。
