Gas detection method, device and equipment for fire alarm and medium

The invention relates to the field of fire early warning, in particular to a gas detection method, device, equipment and medium for fire alarm, and the method comprises the steps: comparing a detected smoke concentration with a preset smoke concentration, and when the detected smoke concentration is higher than the preset smoke concentration, according to environment characteristics and a region model, determining whether the detected smoke concentration is higher than the preset smoke concentration; determining a wind power simulation diagram corresponding to the to-be-detected area; identifying a detection position of the detection equipment from the regional image, and determining a wind power influence value corresponding to the detection position according to the detection position and the wind power simulation diagram; determining a final smoke concentration based on the detected smoke concentration and the wind power influence value, and determining a first weight of the to-be-detected area according t
