Fire disaster escaping distribution type node guiding system based on wireless sensing network

Abstract

The invention relates to a fire-escaping distributed node guidance system based on a wireless sensor network, comprising sensor nodes which are built on each corridor and each aisle in buildings; the sensor nodes are connected in a wireless mode and are connected with a node guidance controller which comprises a node weight initialization module, an emergency publishing module, a node weight adjusting module, a node guidance module and a guiding direction display module; the invention provides a fire-escaping distributed node guidance system based on a wireless sensor network, which has good reliability and can assist people to escape from fire effectively.

Description

technical field [0001] The invention relates to a distributed path guidance mechanism based on a wireless sensor network, in particular to a fire escape distributed node guidance system. Background technique [0002] The modern development of the city makes more and more people work in large modern buildings, especially high-rise buildings. Once a disaster occurs in these densely populated buildings, the consequences will be disastrous if there is no effective guidance to escape from the disaster scene. According to fire statistics data, there were 222,702 fires in my country in 2006, 1,517 people were killed, 1,418 people were injured, and the direct property loss was 784,468,411 yuan. The analysis of the fire department pointed out that when an emergency such as a fire occurs, people often do not know where to escape because of panic. The most common wrong escape methods are: (1) escape by the same route: this is because people entered (2) Escape toward the light source: ...
