Embodiment Construction

[0039] Referring to the attached picture:

[0040] The bus multi-sensor fire detection method of the present invention specifically comprises the following steps:

[0041] Step 1. Collect sensor information distributed in appropriate locations in the bus, and make an assessment result on the fire spontaneous combustion risk of the bus through research and analysis, and store the collected data and assessment results together in the information table set U={x 1 ,x 2 ,x 3 ,x 4 ,x 5 ,x 6 ,d}, where x 1 , x 2 、x 3 、x 4 、x 5 、x 6Respectively represent carbon monoxide concentration, carbon dioxide concentration, temperature, smoke concentration, current intensity, and whether there is flame, d∈{0,1} represents a dangerous situation, 0 represents safety, and 1 represents a fire hazard.

[0042] Step 2: Normalize the collected information table data, use the clustering algorithm combined with the principle of consistent incompatibility to obtain different discretization met...

Abstract

The bus multi-sensor fire detection method uses carbon monoxide sensors, carbon dioxide sensors, temperature sensors, smoke sensors, current sensors, and flame sensors. Through the support vector machine model obtained by discretizing the collected continuous data, it is obtained that each sensor detects The probability of the fire hazard of the bus, and finally use the D-S evidence theory to fuse the information of all the sensor detection results, respectively calculate the probability distribution function of the bus fire hazard after multi-sensor information fusion, and calculate the probability of the bus fire hazard Warning reminder.

Description

technical field [0001] The invention relates to a method in the field of multi-sensor fire detection, in particular to a bus fire detection method. Background technique [0002] As the main mode of transportation for the general public, buses play an irreplaceable role. With the complexity and integration of the electronic control system of the bus, the number of fire accidents during the operation of the bus is also increasing. Due to the dense population, wide distribution of combustibles, and complex operating routes, the bus makes it difficult to evacuate, burn quickly, and fight fires in the event of a fire, which poses a huge threat to the safety of passengers' lives and property. It is not conducive to the normal operation of urban traffic and has serious social hazards. [0003] At present, the research on bus fire detection and early warning in our country is still relatively preliminary. For bus fire early warning, the method of detecting and early warning with s...
