The mechanical pressurization fire-fighting control method according to claim 9, wherein a first monitoring point and a second monitoring point are provided at different locations on the same floor, and a corresponding alarm signal is generated only when the smoke detection value of the first monitoring point and the smoke detection value of the second monitoring point both exceed a preset concentration value.

11. A mechanical pressurization fire control method as claimed in claim 9, wherein a first monitoring point and a second monitoring point are provided at different locations on the same floor, and a corresponding alarm signal is generated only when the smoke detection value of the first monitoring point exceeds a preset concentration value and the second monitoring point emits an alarm bell.

12. The mechanical pressurization fire control system of claim 9, wherein the activation of the pressurization fan is used as a first trigger signal, and the step of triggering the remote closing of the windows of the fire safety zone by the first trigger signal further comprises:

13. The mechanical pressurization fire control method according to claim 9, wherein the step of generating a corresponding release signal when a fire is released and turning off the pressurization fan according to the release signal further comprises: the windows of the fire safety zone can be opened manually.

14. The mechanical pressurization fire control method of claim 9, wherein the detected data of rain, wind pressure, temperature and humidity of the environment outside the floor is used as a third trigger signal, and the third trigger signal can trigger the window of the fire safety area to be closed remotely.
