When the air compressor 7 fails, a shutdown alarm is issued by the information processing center 3 through the voice prompt device 4. The fifth pressure detection device 71 reads the outlet pressure of the air compressor 7 in real time, and when the pressure of the fifth pressure detection device 71 is higher than a set value, the information processing center 3 controls the voice prompt device 4 to give an alarm, and the pressure is automatically released through the first pressure release valve 72.

The third pressure detection means 51 reads the outlet pressure of the gas production device 5.

The fourth pressure detection device 62 is used for reading the pressure value in the gas fire extinguishing pipeline in real time, and when the pressure value reaches a set value, the information processing center 3 controls the voice prompt device 4 to prompt the worker to start fire extinguishing operation.
And a fourth working mode:
performing fire extinguishing operation through an external water source 93, closing the second control valve 22 and the fourth control valve 61, opening the seventh control valve 91, correspondingly opening the sixth control valve 84, and performing fire extinguishing operation by using the spray head 82 to aim at a fire source, wherein the spray head 82 is a hydraulic spray head; the ninth pressure detection device 92 reads the pressure value in the fire-fighting water pipeline, and when the pressure value reaches the set pressure, the information processing center 3 controls the voice prompt device 4 to prompt the staff that the fire-fighting operation can be started.
Furthermore, the method is simple. The operation flow, the attention items and the common fault elimination methods of the equipment can also be stored in the information processing center 3, corresponding columns are clicked on the touch screen, and the operation flow, the attention items and the common fault elimination methods can be viewed through the screen or broadcasted through the loudspeaker in a voice mode.
The fire-fighting system can collect the working state of equipment in real time, feed back information in real time and make corresponding voice prompt, so that workers can obtain the pressure value in the pipeline in real time to judge whether the spraying requirement is met, a specially-assigned person is not required to check and prompt, the operation cost is saved, and the labor is saved. The information processing center 3 can be equipped with a display, and the staff can acquire the pressure information in the pipeline in real time without looking up the pressure gauge by a specially-assigned person.
The fire-fighting system can be applied to a fire truck for fire-fighting operation, but is not limited to the fire truck and can also be applied to other fire-fighting equipment.
