[0059] In some optional embodiments, the second specified condition includes: the smoke concentration is greater than a second specified value; or, a duration that the smoke concentration is greater than the second specified value is greater than a second specified period of time.

[0060] It is assumed that the second specified value is 20 ml/m3, and the second specified period of time is 700 seconds. If the smoke concentration is 32 ml/m3, the second specified condition is satisfied; if the duration is 690 seconds, the second specified condition is not satisfied; and if the duration is 760 seconds, the second specified condition is satisfied.

[0061] In some optional embodiments, the first specified value and the second specified value can be the same or different.

[0062] In some optional embodiments, the first specified period of time and the second specified period of time can be the same or different.

[0063] It should be understood that, the present disclosure is not limited to the flowchart and structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope.
