Abstract

The invention provides a post-earthquake unmanned aerial vehicle emergency material distribution method and device, and relates to the technical field of path planning. The method comprises the following steps: acquiring disaster relief point information, multiple site information, and unmanned aerial vehicle information; based on the disaster relief point information, the multiple site information, and the unmanned aerial vehicle information, conducting a multi-site multi-unmanned aerial vehicle distribution model with the purpose of minimizing the sum of demand weighted arrival times; solving the multi-site multi-unmanned aerial vehicle distribution model through a hybrid genetic algorithm, and obtaining an optimal task planning scheme for each unmanned aerial vehicle to carry out material distribution for one or more victim gathering points. According to the method and the device, for emergency material distribution after an earthquake disaster, the victim gathering points for material distribution of different unmanned aerial vehicles are determined, and a sequence of distribution to the victim gathering points by a plurality of unmanned aerial vehicles starting from different sites is optimized, so that the flight duration of unmanned aerial vehicle post-disaster material distribution is reduced, the material distribution efficiency is improved, and the use efficiency of heterogeneous unmanned aerial vehicles is maximized, and high-quality solutions are obtained.

Description

technical field [0001] The invention relates to the technical field of path planning, in particular to a method and device for delivering emergency supplies by an unmanned aerial vehicle after an earthquake. Background technique [0002] After an earthquake disaster occurs, it is most important to be able to protect people's lives in the first place. Earthquakes are very likely to trigger secondary disasters such as mountain collapses or landslides, resulting in traffic paralysis. Vehicles cannot normally carry out large-scale material distribution on ground roads. Emergency relief materials can be quickly and efficiently distributed to various gathering points of victims for rescue. Work has important practical significance. [0003] Since UAVs are not restricted by terrain factors, they can deliver materials to post-earthquake areas that are difficult for manpower to reach. UAV distribution has been gradually applied to post-earthquake material distribution to solve impor...
