The invention belongs to the technical field of marine navigation, and particularly relates to a marine accident early warning navigation method based on an electronic chart. The method comprises thesteps of acquiring electronic chart information from a current position of a current ship to a preset target port sea area, and displaying a current ship route and current navigation information on the electronic chart; acquiring historical marine accident information of a sea area in a preset range of the current route; judging whether the current ship route passes through the historical marine accident area; if the current ship route passes through the historical marine accident area, displaying a first part of the ship route in the historical marine accident area by using a first warning color, and displaying in the electronic chart; and judging whether a distance between the current position of the current ship and the first part of the ship route is smaller than a first threshold value, if so, carrying out first early warning prompt, and displaying accident information. According to the method, manual operation is reduced, decision-making efficiency is improved, meanwhile, a safenavigation route is provided, and safe navigation of the ship is guaranteed.

    本发明属于海上导航技术领域,尤其涉及一种基于电子海图的海上事故预警导航方法。包括:获取当前船舶当前位置至预先设定的目标港口海域的电子海图信息,在电子海图上显示当前航线和当前航行信息;获取当前航线所在预设范围内海域的历史海上事故信息;判断当前航线是否经过历史海上事故地区;若当前航线经过历史海上事故地区,则使用第一警示色显示处于历史海上事故地区的第一部分航线,并在电子海图中显示;判断当前船舶的当前位置与第一部分航线的距离是否小于第一阈值,若是,则进行第一预警提示,并显示事故的信息。该方法减少人工手动作业、提高决策效率,同时提供安全的航行路线,保证船舶的安全航行。
