The invention discloses a post-disaster real-time
search and rescue method based on a self-help sensor network and a post-disaster real-time
search and rescue system based on the self-help sensor network. The method comprises the following steps of: 1, generating strength adjustable medium and
high frequency signals by a
search and rescue signal transmitter; 2, receiving the medium and
high frequency signals and converting the medium and
high frequency signals into electrical energy by a
distress signal generator, and driving the
distress signal generator to generate medium and high frequency distress signals of specified frequency; and 3, performing seamless capture on the medium and high frequency distress signals and determining the
azimuth and the distance of rescued personnel by a
distress signal identification positioner. The search and rescue
signal transmitter, the distress
signal generator and the distress signal identification positioner are all based on medium and high frequency radio signals; compared with the conventional search and rescue
system, the invention has the advantages that: the
system is free from influence of the environment, the search and rescue measurement range can be enlarged, the
measurement precision is improved, and meanwhile, the search and rescue efficiency is greatly improved; in addition, the energy of the radio medium and high frequency signals can be converted into the electrical energy, so the problem that the energy is used up is avoided.
