AI Technical Summary

Technical Problem

Existing emergency communication systems are vulnerable to crosswinds during takeoff and landing of drones in extreme weather conditions, resulting in unstable flight attitudes. Satellite links are significantly affected by rain attenuation, making it impossible for drones to fly safely and reliably. Furthermore, satellite communication links are frequently interrupted, making it impossible to provide continuous and reliable multi-network access services to disaster-stricken areas.

Method used

By using catapult-launched drones equipped with public network base stations and self-organizing network terminals, combined with satellite relay networks and ground station communication networks, a stable communication link is built through multiple tethered drones and portable satellite stations, enabling continuous concurrent communication access for terminals of multiple operator standards. The communication path is dynamically adjusted using a routing decision engine and a weather attenuation prediction unit.

Benefits of technology

Under extreme weather conditions, it provides stable emergency communication support for disaster-stricken areas, solves the problems of satellite link interruption and multi-mode terminal access, and realizes continuous concurrent communication access for mobile terminals of multiple operators.

Abstract

This invention provides a communication support method and system for emergency rescue unmanned patrol equipment, relating to the field of emergency communication technology. It includes: a rescue site communication network composed of a ground flight control platform and catapult-launched UAVs; each catapult-launched UAV carries a first self-organizing network terminal and a public network base station, and has a built-in first and second-layer switch; the first self-organizing network terminal connects to the public network base station via the first and second-layer switch; a satellite-finding relay network composed of a satellite portable station, a high-throughput satellite, a ground gateway station, and multiple tethered UAVs carrying multiple self-organizing network terminals; and a ground station communication network composed of a national emergency communication convergence access platform, multiple operator core networks, and access networks. This solves the technical problem of existing emergency communication support systems being unable to establish continuous and reliable multi-network access services in disaster areas with network and power outages. It achieves the technical effect of providing stable emergency communication support to disaster-stricken areas with communication interruptions under extreme weather conditions.
