In this embodiment, detecting the type and concentration of the gas in the air by using the flue gas analyzer in combination with other gas sensors is a known technical means for those skilled in the art, and will not be described herein in detail.
S102: and determining the target gas generated by combustion and the concentration of the target gas according to the current gas detection data and the original gas detection data.
Specifically, the current gas detection data and the original gas detection data are compared, a newly added first gas in the air can be determined, meanwhile, the change of the concentration of each gas in the original gas detection data after a fire occurs is compared, when the concentration increment of a certain gas exceeds a preset value, the gas is judged to belong to a second gas, the first gas and the second gas are target gases generated by combustion, and after the target gases are determined, the concentration of each target gas is determined according to the target detection data.
For example: when the comburent is carbon, when the oxygen in the air is insufficient, the carbon is combusted to generate carbon monoxide, the carbon monoxide is the first gas, when the oxygen is sufficient, the carbon is combusted to generate carbon dioxide, and the concentration of the carbon dioxide in the air can be gradually increased.
S103: and predicting the target combustible and the target combustible amount according to the target gas, the building model and the building property based on a preset first determination rule.
Specifically, after the target gas is determined, the server calls a pre-stored smoke comparison table, the smoke comparison table comprises combustion elements and combustion gas generated by combustion of each combustion element, the determined target gas is compared with the combustion gas in the smoke comparison table, the combustion elements possibly corresponding to the target gas are determined, after the combustion elements are determined, combustible materials possibly containing the combustible elements in the building are judged according to the building properties, a combustion material comparison table is established through big data, the combustion material comparison table comprises the building properties and the combustible materials, a certain corresponding relation exists between the building properties and the combustible materials, namely, after the building properties are determined, the building properties are inquired in the combustion material comparison table according to the building properties, the combustible materials contained in the building can be determined, after the combustible materials are determined, the combustible elements contained in each combustible material can be determined according to the determined combustible materials, and determining the combustible containing combustible elements as target combustible, and knowing the layout and the quantity of the target combustible on the fire scene according to the building model after determining the target combustible, so that the target combustible quantity can be predicted.

In this example, when the oxygen is sufficient, determining the combustion speed of the target combustible according to the change speed of the target gas concentration is a technical means known to those skilled in the art and will not be described in detail herein.
In another example, the oxygen concentration is determined to be in a downward trend according to the oxygen concentration variation curve, the oxygen amount is judged to be sufficient when the variation amplitude of the oxygen concentration is smaller than a threshold value after the oxygen concentration is reduced to a certain concentration, and the fire is judged to be extinguished when the variation amplitude of the oxygen concentration is smaller than a threshold value.
When the difference value of the oxygen concentration in each preset time period is larger than a preset value and the oxygen concentration change curve becomes a descending trend along with the increase of the combustion time, the oxygen concentration is judged to be insufficient, when the oxygen concentration is insufficient, the oxygen concentration of a fire scene is detected in real time, and when the oxygen concentration is smaller than a first preset value or the slope of the oxygen concentration change curve is smaller than a second preset value, the fire is judged to be extinguished, wherein in the embodiment, the first preset value and the second preset value are both 0. By adopting the mode, the fire disaster can be predicted to a certain extent, the fire disaster situation can be roughly known without entering the fire disaster field, and the corresponding strategy can be conveniently formulated in real time according to the fire disaster situation so as to reduce the loss caused by the fire disaster.
