An intelligent lifesaving system based on NFC and LoRa communication and unmanned aerial vehicle technology

Abstract

The invention belongs to the field of emergency rescue and rescue, and relates to intelligent distress signal transmission, in particular to an intelligent rescue method and system based on NFC near-field communication, LoRa low-consumption long-range communication technology and unmanned aerial vehicle technology. According to the method and the system, the LoRa communication equipment carried onthe unmanned aerial vehicle platform is used for collecting the help seeking information sent by the LoRa node under the extreme environment condition that a conventional communication environment islacked or damaged, so that the state of a rescue target is determined, and a communication channel between the rescue target and the target is constructed. The mobile terminal in the system serves asa user interface terminal, activates the lifesaving system through NFC communication and sends out help seeking information in time. The LoRa node communication module has the advantages of being lowin power consumption, high in penetrating power, long in remote communication distance and the like, is suitable for information communication under the conditions of natural disasters and severe living environments, and can dynamically form a communication network with an LoRa gateway carried on an unmanned aerial vehicle platform to transmit rescue target characters, positions and other information.

Description

technical field [0001] The invention belongs to the field of emergency lifesaving and rescue, and relates to intelligent distress signal transmission, in particular to an intelligent lifesaving method and system based on NFC near-field communication, LoRa low-consumption long-distance communication technology and unmanned aerial vehicle technology. Background technique [0002] With the rapid development of modern communication technology, people have more and more means and solutions for rescue and lifesaving in the face of various natural disasters or harsh environments. In various rescue and lifesaving processes and environments, the timely acquisition of the distress signal of the rescue target, including location information, has become a crucial part of the entire rescue and lifesaving process. The rescue target can send a distress signal through mobile terminal platforms such as mobile phones, and send out the collected physical location information and other environm...

AI Technical Summary

Problems solved by technology

[0003] However, in many specific situations, the process of people sending out distress signals will encounter great influence and limitations of the communication environment

Especially in the extreme environment of large-scale natural disasters, damage to communication networks, or lack of communication network coverage in oceans, deserts, and mountains, it will be a great challenge to send out distress messages and obtain timely rescue.

Specifically, the restrictions on sending distress messages mainly lie in: natural disasters such as earthquakes cause the communication base stations to be destroyed, and the rescuers lack the communication network, and cannot send voice or text distress messages through the communication operator network base stations; Material partitions, unable to connect to surviving wireless networks such as Wi-Fi gateways and other wireless communication devices; limited power supply, unable to continuously send out distress signals, etc., are people seeking help, especially when trapped in ruins Below, on the mountains or above the vast sea, the major challenges

Missing the timely sending of the distress message may lead to the delay or failure of the rescue operation, resulting in heavy loss of life and property
