Method for preventing boats from colliding

Abstract

The invention discloses a method for preventing boats from colliding, comprising the following steps: performing program initialization; reading information of any two boats, predicting the track of the boats; judging whether the predicted tracks of two boats intersect, if not, returning to step 2 to continue reading the information of any other two boats to predict the tracks of other boats, if yes, calculating the intersection point, and entering the next step; calculating the intersection point, and using a Mercator projection transformation formula to calculate the distance between the intersection boats and the intersection point and a time zone from the boats to the intersection point; judging whether the time zones of two boats have intersection, if not, returning to step 2 to continue reading the information of any other two boats to predict the tracks of other boats; if yes, entering the next step; and giving alarms. The invention uses the Mercator projection transformation, which ensures that the distance between any two points is more accurate and prediction results are more correct; in addition, the invention adopts the judging method of the time zone, which can comprehensively predict time for boats to travel to a designated site, so that the reliability of the prediction result can be improved.

Description

technical field [0001] The invention relates to a ship collision avoidance method, in particular to a ship collision avoidance method which can more comprehensively predict the time required for the ship to sail to a designated place and improve the reliability of the prediction result. Background technique [0002] Ship collision avoidance is a regular action to ensure the safety of navigation during ship navigation. In the previous collision avoidance systems studied by the maritime industry, the information source partly relied on radar and some artificially input signals for a long time. Although new information sources such as GPS have been added in recent years, the inaccuracy of radar information has not been resolved. For other collision avoidance systems, their algorithms for ship collision avoidance are too complex, with a large amount of calculation and a lot of calculation storage space consumed. The advantage of the AIS system (Automatic Identification System f...

AI Technical Summary

Problems solved by technology

For a seaport, there must be many ships that the user needs to monitor, the amount of data received is large, the amount of calculation for ship collision avoidance will be large, and the calculation and storage space consumed will also be large. The forecast is not necessarily accurate, so the real-time and accurate advantages of the AIS system cannot be reflected
