The invention relates to a fishing boat off-site berthing information extraction method which comprises the following steps: finding out berthing time periods from boat position observation data, recording starting positions and ending positions of the berthing time periods, and obtaining starting time and ending time of the berthing time periods according to the starting positions and the endingpositions; calculating the duration of the berthing time periods according to the starting time and the ending time of the berthing time periods, and arranging the berthing time periods according to the descending order of the berthing duration; extracting longitude and latitude coordinates of geographical positions of berthing from the first 10 berthing time periods according to the descending order of the berthing, sequentially obtaining each berthing time period according to the sequence, and obtaining provinces, cities and districts and counties to which the berthing ships belong by adopting an inverse address query mode; and storing the obtained provinces, cities and districts and counties to which the berthing areas belong into a database, and finding out ships berthing in differentplaces. The off-site berthing of the fishing boat can be extracted from the Beidou ship position data.

    本发明涉及一种渔船异地停靠信息提取方法,包括以下步骤:从船位观测数据中查找出停船时间段,并记录下这些停船时间段的开始位置和结束位置,根据开始位置和结束位置得到停船时间段的开始时间和结束时间;根据停船时间段的开始时间和结束时间计算这些停船时间段的时长,并按照停船时长的从长至短进行排列;从排在前10的停船时间段中按照停船时长从长至短的顺序,提取停船的地理位置的经纬度坐标,并按照顺序依次获取每一个停船时间段,并采用逆地址查询的方式获取停船地所属的省、市、区县;将得到的停船地所属的省、市、区县存入数据库,并查找出异地停靠的船只。本发明能够从北斗船位数据中提取渔船的异地停靠。
