Embodiment 1
[0064] Description of known conditions: in size 10×10×10m 3 There is a fire source in the warehouse (there is no other object in the warehouse except the fire source), and the time when the fire occurs is t 0 , arrange 16 sensor observation nodes at the top of the warehouse (Z=0), the arrangement of sensor observation points is as follows image 3 As shown, (the roof is flat, the wind speed is less than 0.1m / s, the measured air source strength is Q=25mg / s, and the diffusion coefficient D=0.08m 2 / s, noise w i is Gaussian noise).
[0065] t=1-50s, the smoke concentration value measured by the sensor As shown in Table 1.
[0066] Table 1 Smoke concentration values measured by sensors
[0067]
[0068]
[0069]
[0070]
[0071] Among them: taking the first row of data in the table as an example, at t=1s,
[0072] means (x 1 ,y 1 ) corresponds to the smoke concentration value measured by the sensor at the position of coordinates (-4,4);
[0073] mean...
