The fire detection method provided by the embodiment of the invention comprises the following specific steps:
referring to fig. 1, in step S100, an ambient temperature value in the energy storage battery cabinet is obtained.
In this embodiment, the ambient temperature value is a temperature value of an environment inside the energy storage battery cabinet, and if the ambient temperature value is too high, a fire may occur in the energy storage battery cabinet or a risk of the fire may occur.
And step S200, obtaining the smoke concentration value in the energy storage battery cabinet.
In this embodiment, the smoke concentration value refers to a concentration value of smoke generated after combustion of combustible substances in the energy storage battery cabinet. If the smoke concentration value is too high, a fire condition may occur in the energy storage battery cabinet or the risk of the fire condition may occur.
And step S300, acquiring a gas concentration value in the energy storage battery cabinet.

The gas concentrations include: a hydrogen concentration, a carbon monoxide concentration, or a volatile organic compound concentration.
When the gas concentration value is obtained, one or two or all of the hydrogen concentration, the carbon monoxide concentration and the volatile organic compound concentration may be obtained at the same time.

In step S434, if the smoke concentration value is greater than or equal to the first concentration value, it is determined that the smoke concentration value satisfies the fire alarm condition.
In this embodiment, if the smoke concentration value is greater than or equal to the first concentration value, it may be considered that the current smoke concentration value is relatively large, and a fire may occur.
The first concentration value comprises a first smoke concentration value and a second smoke concentration value, the first smoke concentration value is 5% obs/m, and the second smoke concentration value is 15% obs/m. And if the smoke concentration value is greater than or equal to the first smoke concentration value, judging that the smoke concentration value meets a first fire alarm condition. And if the smoke concentration value is greater than or equal to the second smoke concentration value, judging that the environmental temperature value meets a second fire alarm condition.
Referring to fig. 5, in step S441, it is determined whether the gas concentration value is greater than or equal to the second concentration value.
In this embodiment, the second concentration value is a critical value for determining whether the gas concentration value meets the fire alarm condition, and if the gas concentration value is smaller than the second concentration value, the current gas concentration value is considered to be relatively small, so that there is no risk of fire.
In step S443, if the gas concentration value is greater than or equal to the second concentration value, it is determined that the gas concentration value satisfies the fire alarm condition.
In this embodiment, if the gas concentration value is greater than or equal to the second concentration value, it may be considered that the current gas concentration value is relatively large, and a fire may occur.
