Personnel characteristic-based fire evacuation path navigation method

Abstract

The invention discloses a personnel characteristic-based fire evacuation path navigation method which comprises the following steps: 1, obtaining fire behavior information through a fire detector, calculating an effective time range capable of being used for escape of each path; 2, reading personnel label information by using an RFID (Radio Frequency Identification) reader-writer, locating personal position information, performing personnel evacuating speed classifying according to the obtained personnel label information and the obtained personnel position information; 3, for personnel with different speeds, calculating evacuating path information by using a shortest path precedence algorithm, wherein the evacuating path information comprises a shortest path length value from an initial position to an outlet node D and all nodes on the path; and 4, sending the shortest path length value and all nodes on the path to personnel to be evacuated. According to the personnel characteristic-based fire evacuation path navigation method, the utilization rate of the path can be effectively increased.

Description

technical field [0001] The invention relates to life-saving and fire-fighting technology, in particular to a fire evacuation path navigation method based on personnel characteristics. technical background [0002] For a long time, fire has always been one of the main disasters that threaten the safety of human life and property. When a fire occurs, it is necessary to quickly and effectively evacuate the crowd in the building to reduce casualties caused by the fire. Compared with the past, today's buildings are more complex in structure and larger in scale, and the passages in the buildings are often criss-crossed and numerous in number. In this complex environment, how to choose an optimized escape route for the people to be evacuated becomes the key to the success of the evacuation. [0003] At present, many evacuation route selection methods have been proposed and put into use. These methods are based on relevant theories of optimization or graph theory, and can find op...

AI Technical Summary

Problems solved by technology

First, these methods often consider the static evacuation environment, ignoring the impact of fire spread on escape

Second, these methods indiscriminately give the same escape path to all persons to be evacuated at the same location

The above disadvantages make it possible for the people to be evacuated to be unable to effectively implement the evacuation instructions and fail to escape successfully before the fire intensifies
