1. An apparatus comprising circuitry for implementing an intelligent system for search and rescue in a special environment such as a disaster, comprising a body surface feature extracting apparatus, a vital sign extracting apparatus, a speech feature extracting apparatus and a network transmission apparatus that are successively in communication connection with one another, wherein the body surface feature extracting apparatus comprises a controller that is configured to cause an image-acquisition circuit to acquire at least one image, with each of the at least one image comprising at least one object to be identified; to cause a convolution circuit to carry out convolving and pooling each of the at least one image, and to then cause each such convolved and pooled image to be input into a trained gated recurrent unit network model to extract features from each of the at least one object to be identified;
wherein the vital sign extracting apparatus comprises a vital sign collecting module configured to acquire information indicative of a blood pressure, a blood oxygen saturation degree, a body temperature, a respiratory rate and a heart rate, and a global positioning system (GPS) or Beidou injured person positioning module provided with a positioning chip for acquiring a position of an injured person;
wherein the speech feature extracting apparatus comprises a sound collecting module, a sound feature extracting module and a sound analyzing and processing module that are successively in communication connection with one another, with the sound analyzing and processing module being provided with a noise database comprising a plurality of ambient sounds and configured to perform denoising by eliminating the ambient sounds in the noise database through wavelet analysis; and
wherein the network transmission apparatus comprises a Zigbee network communication module, a network transmission module, a drone network relay module and a network receiving base station that are successively in communication connection with one another, with the Zigbee network communication module being configured to transmit information of body surface features, vital signs, sounds and positions, the network transmission module configured to automatically search for and send information to a relay network, the drone network relay module configured to receive data and send the data to a receiving network, and the network receiving base station configured to receive data and transmit the data to a server.
