The invention discloses a ship navigation aid safety alarm method and system, and the method comprises the steps: obtaining the ship information of a current ship, the ship information comprises the current water depth of the current ship, the current speed of the current ship, the distance between the current ship and other ships, the relative speed of the current ship and other ships, the relative direction of the current ship and other ships, the relative transverse distance between the current ship and other ships, and the relative course angle between the current ship and other ships; the relative water flow velocity of the current ship and other ships and the relative drifting direction of the current ship and other ships; setting a first ship navigation aid safety alarm model, calculating a first collision risk index according to the ship information, setting a second ship navigation aid safety alarm model, calculating a second collision risk index, and summing and averaging the first collision risk index and the second collision risk index to obtain a final collision risk index; and performing safety warning on the current ship according to the final collision risk index.

    本发明公开一种船舶助航安全告警方法及系统,该方法包括:获取当前船舶的船舶信息,其中,船舶信息包括:当前船舶的当前水深、当前船舶的当前速度、当前船舶与其他船舶的距离、当前船舶与其他船舶的相对速度、当前船舶与其他船舶的相对方向、当前船舶与其他船舶的相对横向距离、当前船舶与其他船舶的相对航向角、当前船舶与其他船舶的相对水流速度和当前船舶与其他船舶的相对漂流方向;设置船舶助航安全告警第一模型,并根据船舶信息,计算第一碰撞风险指数,设置船舶助航安全告警第二模型,计算第二碰撞风险指数,对第一碰撞风险指数和第二碰撞风险指数进行求和平均,获取最终碰撞风险指数;根据最终碰撞风险指数对当前船舶进行安全告警。
