Ship anti-collision method

Abstract

The invention relates to a ship anti-collision method. On the basis of active anti-collision detection, technical features of passive informing and active avoiding are added, relationship of positions and directions of ships is informed each one another, and the ship reporting alarm takes the initiative to avoid collision after acquiring warning message. With the method, the warning information is sent to the rear ships sequentially from the front ship and is sequentially transmitted backward from front in a passive informing manner, and the warning information can be received when the distance between the rear ship and the front ship is smaller than preset safe distance; when the warning information is received, output power of an engine is reduced to prevent a driver continuously controlling the ship ahead or assist an unresponsive driver to slow down.

Description

technical field [0001] The invention relates to the field of ship safety, more specifically, to a method for ship anti-collision. Background technique [0002] In the civilian field, in the ship collision prevention of the prior art, the method of actively obtaining the distance is adopted for ranging, such as sending infrared rays or ultrasonic waves, and receiving reflected infrared rays or ultrasonic waves, and then completing the ranging. [0003] Chinese invention patent application 201611114936.2 discloses a ship anti-collision alarm. Sensors are respectively fixed on the bow, stern, port side and starboard side of the ship. The sensors are equipped with proximity sensors and infrared sensors in the glass cover. The signals of the proximity sensors and infrared sensors form electrical signals through the signal integrator, and the electrical signals pass through the It is wirelessly or wiredly connected with the alarm circuit provided in the hull. [0004] The above-...

AI Technical Summary

Problems solved by technology

[0005] The active detection of obstacles is carried out in the form of signal reflection, and it is impossible to identify whether the approaching obstacle is a ship or other drifting objects

And the detection of the surroundings is indiscriminate detection, and it is impossible to distinguish the low-risk state of parallel driving from the high-risk state of possible collision, so corresponding measures cannot be taken

Moreover, when the detection distance is less than the safe distance, it will not actively slow down, limit the speed or avoid operations on the ship, and does not provide further safety guarantee for the ship
