Technical Field

[0002] In the field of modern fire fighting technology, the development of fire extinguishing systems has been continuously improving. Traditional fire fighting methods mainly rely on manually controlled spraying of fire extinguishing agents. This method has obvious defects and is difficult to meet the needs of complex fire scenes. Manually controlling the spraying amount of fire extinguishing agents is often difficult to be accurate, which may lead to excessive or insufficient spraying of agents. In this case, not only is the fire extinguishing agent wasted, but the fire may not be effectively extinguished due to insufficient agents. In addition, during the fire extinguishing process, the replenishment of agents often requires manual operation, which increases the complexity and time of the fire extinguishing operation. When the fire is fierce, untimely replenishment may lead to interruption of fire extinguishing, affect the fire extinguishing effect, and even bring greater safety hazards.
[0003] Most of the existing fire extinguishing agent spraying devices can only realize a single function, lack automation and intelligent control, and cannot be flexibly adjusted according to the actual fire extinguishing needs. This single-function device seems to be powerless when facing a complex and changeable fire environment. Although there are some automatic spraying and replenishment technologies, most of them cannot achieve precise quantitative control, and the spraying and replenishment process is also difficult to achieve full automation. The fire extinguishing systems in the prior art mostly use simple liquid level sensors or time controllers. These methods are lacking in accuracy and response speed and cannot meet the needs of efficient fire extinguishing.
[0004] These problems and defects of the prior art often make it difficult to accurately control the amount of fire extinguishing agent sprayed during the actual fire extinguishing process, resulting in low fire extinguishing efficiency; untimely replenishment of fire extinguishing agent may cause the fire extinguishing process to be forced to be interrupted; lack of automation and intelligent control, unable to flexibly adjust the spraying and replenishment strategies according to the fire situation. The existence of these problems and defects makes it particularly important to develop a control method that can achieve quantitative spraying and automatic replenishment of fire extinguishing agent. This method can not only improve the efficiency and effect of fire extinguishing, but also reduce agent waste, ensure the continuous supply of fire extinguishing agent, and effectively solve many problems in the prior art.
