Method and system for judging ship arrival and departure and acquiring ship trajectories based on GPS information

Abstract

The invention provides a method and a system for judging ship arrival and departure and obtaining ship trajectories based on GPS information. The method comprises the following steps: step 1, obtaining GPS position information of the ship within preset time; step 2, determining a position point in the preset area of each port according to the GPS position information, and then determining the timepoint when the ship enters and exits from each port according to the position point in the preset area of each port and the time sequence of the position points; and step 3, calculating the walking track of the ship in the preset time according to the GPS position information of the ship in the preset time. According to the method, the arrival and departure time of the ship can be effectively judged, the walking trajectories of the ship can be obtained, and the maritime affair department can remotely know the basic information of the ship through the informatization system by providing the method for judging the ferry entering and leaving the port and knowing the shipping trajectories of the ferry so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of sea area traffic management, in particular to a method and system for judging the entry and exit of ships and obtaining the track of the ships based on GPS information. Background technique [0002] Ferries are an important means of transportation for residents living near rivers, and ferry safety monitoring is also one of the key tasks of the maritime department. At present, the understanding and monitoring of the status of ferry shipping mainly depends on the direct on-site inspection of the maritime department, which requires a relatively large manpower investment, and the records of relevant information can only be recorded by hand and kept on paper. Due to the vastness of China, most cases can only be spot checks, so it is difficult to truly know whether the ship is traveling according to the prescribed route, and whether it has departed or arrived at the prescribed time, and monitoring is more difficult.
