Vessel anti-collision system and corresponding method for actively transmitting sail information

Abstract

The invention discloses a ship-collision preventing system which automatically and continuously sends the sailing information of a ship to neighboring ships, and each set of the sailing information comprises 140 bits of materials, which needs no more than 0.1 second to be transmitted if a pager encoding is adopted, in other words, each channel can transmit 10 sets of the sailing information in each second; if three channels are adopted, then the sailing information of 30 ships can be transmitted in each second. A ship can compute the distances to neighboring ships when receiving the sets of sailing information of the neighboring ships and further simulate how each neighboring ship sails subsequently; if a collision is found to possibly happen, the driver is prompted immediately to take an action to avoid the collision event. The system of the invention has an opposite operation way to traditional radars, and the operations of the traditional radars are that the radar is used for detecting the ships existing nearby and the ships are detected passively by the radar, but the system of the invention leads the ships to actively report the sailing information to other ships, and only one radar needs to be arranged in each ship.

Description

【Technical field】 [0001] The invention relates to the field of combination of computer and communication technology, especially the system and method for improving the navigation safety of ships. 【technical background】 [0002] At present, when a general ship is sailing, the captain is the driver to control the ship. In case of a mistake, it will cause an accident, and the ship driver usually observes other sailing ships, especially small ships, with the naked eye to observe the surrounding environment. When it is found that the safe distance between your own ship and other nearby ships is not enough, you must take immediate action to change the navigation route to maintain a safe distance from other ships. This kind of other sailing ships that use the naked eye to detect the surrounding environment must Rely on the driver's experience, judgment and reaction. When the driver makes a wrong judgment, there will be a chance of a collision accident, especially in bad weather, su...

Problems solved by technology

[0002]At present, when a general ship is sailing, the captain is the driver to control the ship. If something goes wrong, it will cause an accident, and the driver of the ship usually observes the surrounding environment with the naked eye For other sailing ships, especially small ships, when the driver finds that the safe distance between his own ship and other nearby ships is not enough, he should take immediate action and change the sailing route to maintain a safe distance from other ships. Using the naked eye to detect other sailing ships in the surrounding environment depends on the experience, judgment and reaction of the driver. When the driver makes a wrong judgment, there will be a chance of a collision accident, especially in bad weather. Collision accidents are prone to occur. For example, in some areas where heavy fog often occurs, such as Chongqing and the Three Gorges area of ​​the Yangtze River, when there is heavy fog, collision accidents are prone to occur, so most ships have to stop sailing, seriously affecting the Water transportation is an extremely unresolved problem
