Fire extinguishing system control method and fire fighting device

Abstract

The application discloses a fire extinguishing system control method and fire-fighting equipment, and relates to the technical field of fire fighting. The fire extinguishing system control method is applied to a fire extinguishing system. The fire extinguishing system comprises a water system, a foam raw liquid system, a compressed air system, a mixer and a spray gun. The water system, the foam raw liquid system and the compressed air system respectively deliver water, foam raw liquid and compressed air to the mixer to be mixed to obtain compressed air foam. The spray gun is used for spraying the compressed air foam. The fire extinguishing system control method comprises the following steps: obtaining the compressed air foam pressure at the input end of the spray gun; comparing the compressed air foam pressure with a preset spraying pressure value; if the compressed air foam pressure is smaller than the spraying pressure value, increasing the output water pressure of the water system under the condition that the output water flow rate is unchanged, and increasing the output air pressure of the compressed air system. The fire extinguishing system control method can maintain the spraying pressure and flow rate of the spray gun and improve the fire extinguishing efficiency in a high-rise fire scene.
