Problems solved by technology
However, there are two problems in the existing research and application of water injection: First, the distribution of water bodies on the ground can be predicted by using the existing water injection model, but it is still necessary to rely on the experience and professional knowledge of the crew to judge how to cover the fire scene, and the lack of inclusion Consideration of fire extinguishing efficiency due to fire site factors: Second, the complexity of the existing water injection model is still very high. The method based on this type of model cannot quickly optimize the water injection strategy with the existing computing resources, and it is difficult to meet the needs of rapid emergency response. Demand, no on-site auxiliary decision-making support capability

Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings and examples. It should be understood that the following examples are intended to facilitate the understanding of the present invention, and have no limiting effect on it.
[0040] refer to figure 1 , the method for optimizing the strategy of rapid water injection and fire extinguishing based on the particle swarm algorithm of the present embodiment includes the following steps:
[0041] S1: Establish a water injection model. The water injection model is the core content of the water injection strategy optimization method. It is necessary to establish the relationship between the water injection strategy and the water injection distribution of the water body, and establish a new model based on the water injection model. Reduce the calculation amount of water distribution from the water distribution strategy to the water body. refer to figure 2 , the establishment of th...

The invention belongs to the field of computer simulation, and proposes a strategy optimization method for rapid water injection and fire extinguishing based on particle swarm algorithm. The present invention introduces fire field constraints on the basis of integrating existing water injection models, and establishes corresponding fire extinguishing efficiency evaluation indexes; at the same time, discretely expresses fire field constraints and describes the ground distribution of numerical water injection models with polygons Using the neural network to establish the proxy water injection model of aircraft water injection strategy and ground distribution; finally using the agent water injection model to optimize the fire extinguishing efficiency, and using the particle swarm optimization algorithm to quickly optimize and formulate the water injection strategy. To determine the current aircraft at what altitude, what speed, at what angle and from what track point to perform the water injection operation. The invention is beneficial for the unit to respond to forest fire dangers faster, improves the fire extinguishing efficiency in the water throwing stage, thereby improving the efficiency of the entire fire extinguishing task, and enhancing the aviation emergency response capability for forest fire extinguishing.
Description
technical field [0001] The invention belongs to the field of computer simulation, and in particular relates to a strategy planning method for rapid water injection and fire extinguishing based on a particle swarm algorithm, in particular to the optimization of an aircraft single sortie rapid water injection and fire extinguishing strategy based on a proxy water injection model and a discretized fire field model. Background technique [0002] Forests are the main body of terrestrial ecosystems. As an extremely important ecological protection barrier, forests have an important impact on sustainable development and ecological protection construction. However, fires have seriously damaged forest resources and the ecological environment. According to statistics, hundreds of thousands of forest fires occur every year all over the world, and the affected area reaches several million hectares. The situation of forest fire emergency rescue is very serious. However, due to the compl...
