Embodiment Construction

[0047] Combine below Figure 1 to Figure 2 , the present invention is further described:

[0048] refer to figure 1 , figure 1 Shown is a flow chart of establishing a precise trajectory model of an electronic fence according to an embodiment, including the following steps:

[0049]S10: Acquire, according to the ship's GPS locator, a track point that the ship sails through, and the track point is a coordinate point that represents the current position of the ship and is sent to the base station by the ship's locator.

[0050] The above steps, based on the data recorded by the ship automatic identification system AIS, obtain the trajectory points that the ship passes through, and the trajectory points are the "nodes" on the path, and the "nodes" include the ship's precise ship position, course, speed (vector line), Dynamic information such as steering speed and distance to the nearest ship, and static information such as ship name, call sign, ship type, length and breadth, an...

Abstract

The invention relates to an electronic fence system and a method for establishing a precise trajectory model of the electronic fence, comprising the following steps: Step 10: Acquire the trajectory points passed by the ship according to the GPS locator of the ship, and the trajectory points are sent to the base station by the ship locator is the coordinate point representing the current position of the ship; step 20, denoise all the track points, compare the existing track points, remove the track points with larger deviation, and obtain a smoother ship track; step 30, according to The generated ship template trajectory calculates the time required for the ship to arrive at a certain destination according to the algorithm of the ship's expected arrival days. The present invention needs to conduct unified management on the positioning of ships and vehicles through electronic fences, perform data analysis on their trajectories and predict the required time for them to reach the destination, thereby dynamically repairing the trajectory model and improving the accuracy of the model.

Description

technical field [0001] The invention relates to an electronic fence system and a method for establishing a precise trajectory model of the electronic fence. Background technique [0002] The electronic fence is a new generation of electronic fence system produced by combining traditional electronic fence technology and network technology. It is mainly composed of electronic fence host, intelligent control keyboard and management software. Users can supervise the electronic fence through the network and realize user information. Real-time delivery, data interaction and remote supervision functions, etc. [0003] But the traditional electronic fence has the following problems: [0004] 1. Over-reliance on hardware devices makes it difficult to share data and analyze and predict big data. [0005] 2. It is impossible to dynamically adjust and update the status of electronic fence related events through a large amount of data accumulation. [0006] 3. It is not easy to integr...
