| Abstract: | In recent years, various natural disasters and emergencies have occurred frequently at home and abroad, and the demand for emergency rescue has gradually increased. Helicopters are widely used in emergency rescue due to their advantages such as fast rescue speed, high efficiency, and strong professionalism. However, the path planning in helicopter emergency rescue lacks mission-driven considerations, which can easily lead to insufficient helicopter emergency rescue efficiency, and often the impact of the mission environment will be ignored, resulting in the failure of the rescue mission or even a helicopter accident. Based on the classification of helicopter emergency rescue missions, this study focuses on the rescue needs and characteristics of fire extinguishing and medical rescue missions. On the basis of considering the threat of complex terrain environment to rescue missions, through theoretical analysis, modeling and simulation, the A* algorithm is used to plan the feasible path of the helicopter in fire-fighting and medical rescue missions, and the altitude data in ArcGIS is used to obtain the flight height trajectory. By properly planning the helicopter's flight path and altitude trajectory, terrain threats can be avoided to the greatest extent, the success rate of rescue missions can be improved, and the safety of the helicopter and crew can be ensured. |
