Dynamic encounter state monitoring method and equipment for marine navigation

Abstract

The invention provides a dynamic encounter state monitoring method and equipment for marine navigation. The method comprises the following steps: acquiring a plurality of distance sequence samples; and determining a plurality of angle variations based on each distance sequence sample and a preset angle formula. Wherein the angle variation is in one-to-one correspondence with the encounter distance in the distance sequence sample. And determining a corresponding encounter distance coefficient according to each angle variation and the corresponding encounter distance. Wherein the encounter distance coefficient is matched with the distance variation of the distance sequence sample. And determining the meeting azimuth variation of the current meeting object. And determining the nearest meeting distance with the current meeting object through the corresponding meeting distance coefficient based on the meeting azimuth variable quantity.

Description

technical field [0001] The present application relates to the technical field of marine navigation, and in particular, to a method and device for monitoring a dynamic encounter state for marine navigation. Background technique [0002] With the development of navigation technology, the Active Phased Array Radar (APAR) and gyro compass equipped by marine ships can help sailors to understand the situation of encounters with other ships in time. Therefore, when the nearest encounter distance is more dangerous, the navigator can take the best avoidance measures in time. [0003] However, the ships sailing at sea may not be equipped with APAR radar or the APAR radar may fail, or the gyro compass may fail, which will result in the inability to monitor the surrounding encounter targets (fixed targets, moving targets, etc.) in time. target), it is impossible to determine the encounter state when the ship meets dynamically. This makes it impossible for the navigator to obtain the c...

AI Technical Summary

Problems solved by technology

[0003] However, ships navigating at sea may not be equipped with APAR radar or APAR radar failure, or the gyro compass may fail, which will lead to the inability to monitor the surrounding targets (fixed targets, moving target), the meeting state of the ship dynamic meeting cannot be determined

In turn, the navigators cannot obtain the closest encounter distance with the meeting target, and cannot avoid in time, which increases the probability of marine accidents and the possibility of property damage and casualties
