This invention relates to the field of aviation emergency rescue auxiliary decision analysis, and particularly to a classification and grading method for aviation emergency rescue scenarios. The method first acquires historical case information and designs prompt templates, then uses a large language model to parse unstructured text to obtain structured scenario element data. Next, it constructs a hierarchical structure model for classifying and grading forest fire scenarios, and uses the analytic hierarchy process (AHP) to calculate element weights. Subsequently, it constructs a scoring mapping model, sets monotonicity constraints, and aims to maximize the Pearson correlation between scenario scores and the scale of rescue force deployment, using a trust region algorithm to iteratively solve the model parameters. Finally, it calculates the total scenario score, performs clustering operations based on the deployment scale, and determines the grading threshold based on the cluster centers and dispersion. This invention achieves in-depth utilization of unstructured rescue information, enabling scientific quantification and accurate grading of complex scenarios such as forest fires, effectively improving the scientific nature and response efficiency of aviation emergency rescue decision-making.

This invention discloses a forest fire prevention trenching mechanism, trenching equipment, and its usage method, belonging to the field of forest fire prevention technology. The trenching mechanism includes a pusher component installed on the front side of a support frame and a cutting component on the rear side.

This invention discloses a multi-purpose forest fire fighting water tanker, belonging to the field of forest fire fighting technology. Through a pressure-down mechanism and a support mechanism, when a fire occurs and long-distance water collection is needed, the vehicle, with the aid of its off-road capabilities, selects a relatively flat and stable section of road to park and deploy multiple support structures as nodes. This guides the water pipes around terrain unsuitable for water transport, ensuring smooth water delivery and expanding the applicability of the water collection system. Based on the distance between the water source and the fire site, multiple water pipes are connected through multiple support structures at their ends, forming a water collection channel composed of multiple water pipes and support structures. This improves water collection efficiency and provides reliable water support for forest fire fighting. By securely binding the water pipes to the support structures using ropes, clips, etc., wear and tear caused by displacement due to external forces can be prevented.
