Abstract

The invention discloses a forest fire monitoring method based on a wireless sensor network. The number of sensors needing to be arranged in a forest of a unit area is determined by adopting a Bayesianclassifier; a sensor network is arranged, the four measured basic weather condition parameters are substituted into a pre-established closed form equation of dependence of a fine fuel humidity specification and a fire climate index on weather conditions; the threat degree representing possible fire disasters is calculated, the influence of sensor distribution on the FFMC and the FWI can be quantified, the needed precision is achieved in the FFMC and the FWI, accurate prediction of the forest fire disasters is achieved, meanwhile, the lowest cost is guaranteed, and the method is easy to implement and does not need any specific node deployment scheme. Thus, the nodes may be deployed in a unified manner, such as throwing them from an aircraft. Therefore, node deployment in real life is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of forest fire monitoring, in particular to a forest fire monitoring method based on a wireless sensor network. Background technique [0002] In many parts of the world, forest fires are a regular phenomenon, whether natural or man-made. Fire-prone areas are mostly located in temperate climates, where rainfall is high enough to form large vegetation and summers are very hot and dry, creating dangerous fuel buildups. Global warming will also increase the number of these disasters. Every season, not only are thousands of hectares of forest destroyed by wildfires, but assets, property, public resources and facilities are also destroyed. Additionally, firefighters and civilians are at risk and there are horrific casualties every year. [0003] A variety of fire monitoring methods based on forest wireless sensor networks have also been proposed in the prior art. However, in actual use, the distribution of sens...
