The application relates to the technical field of foam fire extinguishing mixing, and discloses a foam fire extinguishing agent multi-component proportion mixing method and a foam mixing generating device. The foam fire extinguishing agent multi-component proportion mixing method comprises the following steps: acquiring fire scene information in real time through multi-modal sensing, identifying a fire type and an environmental condition by using an edge AI model based on the fire scene information, and generating a structured fire condition label. Through edge AI local reasoning and a straight-through mixing path design, the first dose of foam can be quickly sprayed out after fire confirmation, the golden fire extinguishing time is effectively seized, the method is especially suitable for fast-spreading fire conditions such as lithium batteries, a three-stage composite formula is dynamically called according to the fire condition, high-cost functional components are added only when needed, fire extinguishing efficiency is improved, multi-modal sensing and a closed-loop feedback mechanism are fused, even if there is deviation in initial identification, the components and mixing parameters can be corrected in real time through fire scene feedback, and fire extinguishing failure caused by misjudgment is avoided.

The invention discloses a dry powder extinguishing agent and a preparation method thereof. The dry powder extinguishing agent comprises the following components in percentage by mass: 10-95% of basic aluminum carbonate, 0-85% of bicarbonate or ammonium phosphate, 2-5% of a lubricant, 2-5% of a moisture-proof agent, 2-5% of a flow aid and 2-5% of other auxiliaries. According to the dry powder extinguishing agent with the basic aluminum carbonate as the main component, the problem that a commercially available dry powder extinguishing agent is difficult to effectively inhibit high-temperature environment fire disasters can be solved, and the dry powder extinguishing agent with the basic aluminum carbonate and an existing dry powder effective component compounded component as the main component can achieve the high-low temperature full-temperature-zone effect of the dry powder extinguishing agent; the fire extinguishing efficiency of the dry powder extinguishing agent is improved, and the application range of the dry powder extinguishing agent is expanded.
