A seaport channel ship navigation safety early warning index system construction and risk real-time early warning method comprises the following steps: determining a safety risk factor Ei and a corresponding safety risk factor ri which influence ship navigation of a concerned water area channel according to ship navigation conditions and navigation accident historical data of the concerned water area; determining a quantifiable or semi-quantitative risk index xi corresponding to each safety risk factor Ei and a corresponding safety threshold Yi, and proposing a risk advance coefficient Pi corresponding to the early warning interval; and proposing a comprehensive risk index Gt calculation formula considering the influence of a multi-risk factor combination, and determining a corresponding comprehensive risk level and a real-time main risk factor. Risk levels and main risk factors are displayed in different colors on the electronic navigation channel chart, and early warning information such as visual and auditory sense is sent to a ship driving end and a shore management platform. According to the method, a ship navigation safety index system is scientifically constructed, the real-time comprehensive risk level and main risk factors are reasonably determined, the ship navigation safety can be effectively improved, and the navigation management efficiency is improved.
一种海港航道船舶通航安全预警指标体系的构建及风险实时预警方法,包括:根据关注水域的船舶航行条件和通航事故历史数据,确定影响关注水域航道船舶通航的安全风险因素Ei和相应的安全风险系数ri;确定各安全风险因素Ei对应的可量化或半量化风险指标xi和相应的安全阈值Yi,提出提前预警区间对应的风险提前量系数Pi;提出考虑多风险因素组合影响的综合风险指数Gt计算公式,确定对应的综合风险等级和实时主要风险因素。在电子航道图上分色显示风险等级和主要风险因素,向船舶驾驶端和岸上管理平台发出视觉和听觉等预警信息。此方法科学构建船舶通航的安全指标体系,合理确定实时的综合风险等级和主要风险因素,能有效提升船舶航行安全性、提高通航管理效率。
