An emergency simulation method for UAVs on highways under traffic accidents

Abstract

This patent discloses an emergency simulation method of a highway UAV under a traffic accident. The method is realized by using a highway UAV emergency simulation system under a traffic accident. The method includes: Step 1: Dynamic three-dimensional driving view The scene module initially creates a terrain model through the returned coordinate information of the accident site. Step 2: The interactive simulation control module deploys the UAV scheduling plan according to the distance between the parking apron and the accident point and the UAV state, combined with the UAV mobilization algorithm. , set the simulation parameters to run the simulation to realize the functions of automatic take-off, cruise monitoring, and return of the UAV; this patent can dispatch multiple UAVs for cooperative investigation according to the traffic accident situation, which has a good information acquisition effect and can effectively simulate traffic. accident handling.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an emergency simulation system for expressway unmanned aerial vehicles under traffic accidents. The aim is to mobilize unmanned aerial vehicles to continuously monitor the accident site by simulating a traffic accident on the expressway, so as to obtain road network traffic data, and simulate and evaluate the traffic road network safety situation and emergency control strategy. Background technique [0002] At present, my country's highway mileage ranks first in the world, but there are still problems such as high traffic accident rate and insufficient emergency rescue level, and the death rate of traffic accidents remains high. Due to the imperfection of my country's expressway traffic information collection equipment, it is difficult to obtain complete real-time dynamic road network traffic data, and at the same time, there is a lack of information transmission...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing domestic patents are only for the research on the visual simulation of UAV flight in the simulated flight environment, and have not yet involved the interaction between UAV and ground information to realize traffic simulation

A single UAV flight visual simulation can only perceive the surrounding environment, and cannot specifically reflect the operating status of the entire road network. Attitude and other processing, has not yet involved the acquisition of ground traffic data, such as average speed, road section traffic volume, vehicle driving route, etc., and there is no visual representation of the data in the storage and output of the data, so the existing UAV flight The simulation system cannot analyze and evaluate the dispatching plan of multiple UAVs under traffic accidents and the corresponding emergency strategy plan
