Ship meeting system based on AIS and AP radar sensing information

Abstract

The invention discloses a ship meeting system based on AIS and AP radar sensing information. The system is mainly composed of an information acquisition interface unit, a main control unit, a displaycontrol unit, a VHF communication unit, an alarm control unit, an electromagnetic valve control module and a system command control unit. The main control unit is bidirectionally and electrically connected with the display control unit; the input terminal of the information acquisition interface unit is provided with nine paths of input ports; the information acquisition interface unit is in datatransmission connection with the main control unit; the VHF communication unit is in bidirectional data transmission connection with the main control unit; and a control terminal of the main control unit is in control connection with the alarm control unit, the electromagnetic valve control module and the data processing unit. Compared with the prior art, the disclosed system has the following advantages: he meeting phenomenon can be prompted when two ships meet; he steering engines are automatically operated to ensure that the two ships avoid in time to realize safe sailing; a hidden danger of the ship collision caused by untimely watching of ship driving on duty due to automatic steering navigation is eliminated; and thus the development of intelligent navigation of the ships is promoted.

Description

technical field [0001] The invention belongs to the technical field of ship communication, in particular to a ship encounter system based on AIS and AP radar perception information. Background technique [0002] my country currently has a total of 1.06 million fishing vessels, the country with the largest number of fishing vessels in the world, accounting for about 1 / 4 of the world's total, of which the total number of marine fishing vessels is 316,100. It is understood that some fishing boats above 300KW and ocean-going fishing boats in my country's offshore operations have been equipped with autopilots. Steering device; its working principle is: when the bow of the ship deviates from the original course by a certain angle (yaw angle) due to external forces such as wind, waves, and currents, the device immediately acts to deflect the rudder blades by a certain angle (rudder angle), and the bow is on the rudder. Under the action of force, it gradually returns to the original ...

Problems solved by technology

[0003] However, fishing boats are now equipped with independent radio communication equipment, which are not on the same frequency as merchant ships. When sailing at sea, once they find that they are in danger of colliding with fishing boats or do not understand the other party’s intentions, they cannot get in touch with them effectively, which can easily lead to Uncoordinated avoidance, resulting in dangerous situations or collisions

For example, at about 1 am on March 12, Zhedaiyu 02611 was collided by a merchant ship while returning to the voyage, and 12 people lost contact. Another example is that various fishing grounds in the Yellow Sea form an important southern channel from Chengshantou to Shanghai Port and Ningbo Port. Merchant ships are basically sailing on autopilot, and most of the fishing boats in Tianjin, Hebei, Liaoning, Shandong, and Jiangsu are operating here. When merchant ships enter and leave Qingdao Port, Rizhao Port, and Lianyungang Port, they are in a state of cross sailing with fishing boats. When the communication frequency is not the same Existing navigation hazards
