Method for implementing search and rescue by using unmanned aerial vehicle-mounted EPIRB and photoelectric pod equipment

Abstract

The invention relates to the technical field of unmanned aerial vehicle application, in particular to a method for implementing search and rescue by using an unmanned aerial vehicle-mounted EPIRB and photoelectric pod equipment, when EPIRB equipment is loaded on a loading machine of the unmanned aerial vehicle system to carry out a maritime patrol task, an airborne EPIRB is used for directly receiving distress alarm signals with the working frequency of 406 MHz sent by a ship-borne emergency radio position indicator (EPIRB) distress ship through manual or automatic starting within the action range of an air patrol sea area, and meanwhile optical image high-precision positioning is carried out on the distress ship in combination with image data obtained by airborne photoelectric pod equipment, and accident scene image data and information such as an identification number, a dangerous case type and high-precision position data of a ship in distress can be transmitted back to a search and rescue task control center through an unmanned aerial vehicle radio data chain, so that subsequent rescue work can be timely and quickly decided, deployed and carried out, the search and rescue efficiency is effectively improved, and the personnel and property loss is reduced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle applications, in particular to a method for carrying out search and rescue by using unmanned aerial vehicle-mounted EPIRB and photoelectric pod equipment. Background technique [0002] With the increasing development of the maritime industry, the safety of maritime transportation has become the focus of attention, and the accuracy and timeliness of the search and rescue of ships in distress are particularly important. At present, the ship emergency search and rescue system commonly used in the world is the global satellite search and rescue system (COSPAS-SARSAT). The ship is equipped with a shipboard emergency position indicating radio beacon (EPIRB) with a working frequency of 406MHz. When a ship is in distress, the onboard EPIRB can be activated manually or automatically to send out a distress alarm signal. After being forwarded by the satellite, the local user terminal (LUT) al...

AI Technical Summary

Problems solved by technology

Since the ship emergency search and rescue system uses low-polar orbit satellites or geostationary orbit satellites, the positioning accuracy of the rescue position is low (the positioning accuracy error is 5km), and it takes a long time from the distress signal sent by the ship to the detection by the search and rescue signal system (up to 90min). , and because the emergency position indicating radio beacon (EPIRB) is separated from the ship in distress after the ship is in distress, and floats alone on the water surface, under severe and complex sea conditions, the emergency position indicating radio beacon (EPIRB) may be delayed by the delay of the rescue time. Under the action, the space distance from the first scene of the ship in distress will increase, which will cause the search and rescue system to obtain the position information of the ship in distress from the distress signal transmitted by the satellite, which is not the real position information of the ship in distress, thus delaying the best rescue time and other problems
