Emergency communication method and system based on unmanned aerial vehicle

Abstract

The invention discloses an emergency communication method and system based on an unmanned aerial vehicle, and the method comprises the steps: driving the unmanned aerial vehicle to fly to an emergencyplace after a management center receives urban emergency information, collecting ground information, and constructing a ground wireless node putting position through a decision tree method; selectingthe nearest node as a cluster head node by adopting a centroid algorithm, and constructing a clustering wireless network; driving the wireless communication relay unmanned aerial vehicle to fly to the ground wireless node throwing position, constructing an unmanned aerial vehicle flight gliding algorithm according to the aggregation node position, and obtaining a planned flight path of the wireless communication relay unmanned aerial vehicle; after the wireless communication relay unmanned aerial vehicle is driven to enter the communication range of the cluster head node according to the planned flight path, establishing communication connection after broadcast communication is performed on the cluster head node, and completing emergency data communication. According to the invention, a three-dimensional wireless communication system can be rapidly constructed based on the unmanned aerial vehicle, and real-time dynamic optimal configuration is carried out on network resources.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an emergency communication method and system based on an unmanned aerial vehicle. Background technique [0002] With the rapid development of urban infrastructure, effective monitoring and monitoring of urban public events is an important basis for timely and efficient response to such events. Among them, the emergency response network is the primary link in the handling of sudden environmental events, and is the fundamental basis for timely and correct emergency handling of events, reducing event hazards, and formulating recovery measures; therefore, the construction of urban public emergency response networks occupies an important important position. Especially when super-large cities enter the period of high incidence of urban public emergencies, emergencies will cause irreparable losses of life and property to the people, and have a negative impact on the sustai...

Problems solved by technology

[0004] However, during the research and practice of the prior art, the inventors of the present invention found that the prior art has defects such as difficult deployment, long implementation period, poor flexibility, fixed nodes, heavy workload and low work efficiency; On the other hand, due to the characteristics of changing locations, various types of incidents, three-dimensional and dynamic accident diffusion in urban public emergencies in recent years, it is difficult for the traditional monitoring network to adapt to the above-mentioned new characteristics and cannot meet the needs of the current urban public emergencies. Incident management monitoring and other actual needs
