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.
