A Maritime Search and Rescue Information Transmission Method Combining Human Eye Observation and Machine Signal Detection

Abstract

The invention discloses a human-eye observation and machine signal detection combined maritime search and rescue information transmission method. The method comprises the following steps that (1) one who falls into water emits high-frequency SOS signals by using a worn SOS device to emit high-frequency flickering-light SOS information in the form of Morse codes or other improved encryption codes; (2) a search and rescue staff discovers the SOS signals by discovering the flickering-light SOS information emitted by the distant one who falls into water as well as high-frequency flickering light via the eyes or a telescope; (3) the search and rescue staff analyzes the high-frequency signals via a machine by using a machine signal detector to carry out high-frequency analysis on the high-frequency light and corresponding decoding and further to obtain information of the one, who falls into water, himself / herself as well as the accurate geographic position of the one; and (4) rescue is executed. Thus, information of the one who falls into water can be obtained from high-frequency flickering light, the one can be rescued rapidly, and the search and rescue efficiency is improved.

Description

Technical field: [0001] The invention relates to a method for transmitting maritime search and rescue information, in particular to a method for transmitting maritime search and rescue information combining human eye observation and machine signal detection. Background technique: [0002] With the development of science and technology, the strengthening of the economy, and the increase of sea and air activities, it is inevitable that various accidents will occur in these activities. The biggest hope for those involved in the accident is to get help in the shortest time. Can the rescue force search immediately? Finding the location of the person who fell into the water is the key to helping the person involved in the accident. However, the situation at sea is complicated. Compared with land communication, sea communication has its own environmental characteristics. First, in terms of terrain, there are fewer obstacles at sea, which leads to direct The result is that the radio...

[0002] With the development of science and technology, the strengthening of the economy, and the increase of maritime and air activities, it is inevitable that various accidents will occur in these activities. The greatest hope for those involved in the accident is to get help in the shortest time. Can the rescue force search immediately? Finding the location of the person who fell into the water is the key to helping the person involved in the accident. However, the situation at sea is complicated. Compared with land communication, sea communication has its own environmental characteristics. First, in terms of terrain, there are fewer obstacles at sea, which leads to direct The result is that the radio wave propagation gap is large, so when the radio wave propagates at sea, the diffraction loss is smaller than that on land. At the same time, the propagation gap increases, which increases the radio wave reflection, and when the electromagnetic wave propagates at sea, if the grazing angle is small, The reflection coefficient is relatively large in the microwave band, so the influence of reflected waves is greater than that on land. Sea communication channels are vulnerable to sea surface reflection and atmospheric absorption loss, diffraction loss, cloud and fog attenuation, rain attenuation, wave height and harsh ocean environment. Due to the influence of other factors, it is difficult to determine the location of the person who fell into the water. When someone falls into the water, the search and rescue personnel must immediately obtain the location of the person who fell into the water, so as to facilitate timely rescue
