The invention relates to a ship approach early warning algorithm, which comprises the following steps: comparing the spacing distance between two ships in a suspicious area, when the distance is smaller than a certain threshold value, further judging the duration under the condition that the distance is smaller than the certain threshold value, and when the duration is larger than the certain threshold value, further judging whether the ship starts an AIS (Automatic Identification System) or not. If the AIS is not started, early warning is carried out; if the AIS is started, whether the ship is in a legal list is judged according to the reported ship data, and if not, early warning is carried out. According to the method, ship lapping can be effectively identified, and illegal lapping of the ship can be identified and early warned to the maximum extent.

    本发明涉及一种船舶搭靠预警算法,算法流程为:比较可疑区域里的两只船舶的间隔距离,当距离小于一定阈值时,进一步判断在距离小于一定阈值的情况下,持续的时间长短,当持续的时间长度大于一定阈值时,进一步判断船舶是否开启AIS,如果没有开启AIS则预警;如果有开启AIS,则根据已报备的搭靠船舶数据判断其是否在合法清单里,如果不在,则预警。本方法能有效识别船舶搭靠,最大限度的识别和预警船舶的非法搭靠。
