Description

Technical Field

[0001] The present application relates to an integrated intelligent platform for ship emergency navigation, positioning, search and rescue, and environmental monitoring and pollution prevention, which belongs to the technical fields of ship safety, navigation assistance, search and rescue, environmental monitoring, and pollution prevention. Background Art

[0002] Shipwrecks occur from time to time due to bad weather at sea, improper ship handling, ship collisions and other accidents. At present, there are no standardized, unified, standard and obvious warning (marking) devices to timely mark the location, displacement direction and speed of the shipwreck during the process of the ship sinking and sinking. It is difficult to deploy emergency shipwreck position markers for floating and suspended ships. After the ship sinks, the approximate location of the shipwreck is determined by searching for the VDR-EPIRB (shipborne voyage data recorder-satellite emergency radio position indicating beacon) floating on the sea to obtain the ship's position stored in the VDR. Because the VDR-EPIRB floats on the sea and has no connection with the shipwreck, it will be affected by the wind, waves and currents at sea. The VDR-EPIRB will drift away from the shipwreck with the current and will not be connected to the location of the shipwreck. The exact location of the wrecked ship must be determined through detection and search in a large area of ​​sea, which is time-consuming and laborious. The setting of emergency shipwreck position markers requires approval (a relatively long period of time) before maritime and navigation agencies can organize the deployment of emergency shipwreck position markers. The cause of the accident can be analyzed by searching the ship-borne VDR to obtain the ship's position stored in the VDR, the ship's navigation dynamics before and after the accident, and the bridge commands. This seriously affects the efficiency of search and rescue of life and property, the efficiency of accident handling, and the navigation safety of nearby ships. In addition, searching for VDR-EPIRB and detecting and searching for the exact location of the wreck requires a lot of manpower, equipment, and a lot of time. Summary of the invention
