Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, an exemplary flowchart of a method for determining a ship anchoring area according to an embodiment of the present application is shown.
The method comprises the following specific steps:
s101, identifying the anchoring behavior of the ship.
During the ship sailing process, the anchoring behavior often occurs, and when the anchoring behavior generally occurs, various state parameters of the ship can be changed, which are different from the normal ship sailing behavior, such as abnormal berthing time of the ship, ship sailing track, ship sailing speed, ship sailing direction, ship sailing displacement and other parameters, so that the anchoring behavior of the ship can be identified by utilizing the position change of the ship.
In the embodiment of the invention, the anchoring behavior of the ship can be identified by adopting various methods, for example, the anchoring behavior of the ship can be judged by acquiring a real-time image in the ship navigation process and manually analyzing the abnormal berthing time of the ship in the real-time image, or the ship navigation track in the real-time image is manually analyzed.
In the embodiment of the invention, parameters such as ship navigation speed, ship navigation direction, ship navigation displacement and the like can be judged through certain specific rules, so that the state track of ship breakdown is determined.
S102, analyzing and counting anchoring behaviors;
after step S101, the ship' S mooring behavior needs to be analyzed and counted. Analysis of the mooring behaviour (i.e. the mooring behaviour) is essential during the operation of the vessel. In the field, different anchoring modes, such as bow mooring, ship side mooring, stern mooring, multi-point mooring and the like, can be analyzed according to conditions of different water areas, meteorological conditions and the like, and the ship behavior of a designated ship type, a designated time period and a designated area can be analyzed according to design requirements. In the face of the processing requirement of anchoring informatization, the embodiment of the invention can select and count the accumulated duration and anchoring times of the ship anchoring behavior, thereby effectively monitoring anchoring in a non-anchoring area and anchoring in a protected area in real time and indirectly avoiding damage to submarine resources in the protected area.
And S103, generating anchoring area data of the ship according to the analysis and statistics result.
Analyzing and counting real-time anchoring behaviors, generating anchoring area data based on the anchoring behaviors, providing abundant data resources for other terminal users, such as actual anchoring area position analysis, anchoring area ship flow analysis, anchoring risk maps and the like, thereby realizing diversified management of ship data services and meeting various requirements of other terminal users on anchoring behavior analysis.
With further reference to fig. 2, a detailed flowchart of an embodiment of the present application is shown for identifying the ship 'S mooring behavior in step S101, i.e. after completing the identifying the ship' S mooring behavior, step S102 is performed.
The method for identifying the anchoring behavior of the ship comprises the following steps of:
step S201, optionally adding in different embodiments, and acquiring real-time position data of the ship sent by a data source;
the real-time position data of the ship can be obtained from different data sources, for example, the real-time position data can be obtained through an automatic ship identification system AIS. Ship navigation data (AIS data for short) generated by an Automatic Identification System (AIS) of a ship is a very important type of shipping data and has a huge data volume. The automatic ship identification system AIS is composed of shore-based (base station) facilities and shipborne equipment, is used as a novel digital navigation aid system integrating multiple technologies, can acquire ship dynamic information such as ship position, ship speed, course rate and course and the like from a Global Positioning System (GPS), and generates AIS data by combining ship static information such as ship name, call sign, draft and dangerous goods.
In addition, other data sources capable of acquiring real-time position data of the ship, such as a radar or Beidou satellite navigation system, may be selected in the art.
Step S202, which is optionally added in different embodiments, preprocesses the real-time location data.
After the real-time position data of the ship is acquired, different preprocessing needs to be performed on the real-time position data of the ship input by different data sources based on factors such as data formats and inconsistent data contents of the data sources. Through the preprocessing of the ship behavior data, the quality of the ship behavior data can be guaranteed, and reliable basic analysis data are provided for ship behavior identification.
In some embodiments of the present invention, one or more of a plurality of data processing manners may be adopted, and the specific selection is adjusted according to the actual design requirement, for example, data fusion processing, repeated data cleaning, error data cleaning, data sorting and data interpolation processing.
The data fusion processing can carry out track association, fusion processing and the like on the real-time position data of the ships of different data sources, so that more accurate and comprehensive real-time position data of the ships can be obtained. Repeated data cleaning can remove repeated redundant data in the real-time position data of the ship, so that the calculation processing time is not reduced, and the timeliness of data processing is improved. And error data cleaning can delete obvious data belonging to abnormal values or error values in the input data of the data source, so that the data processing quality is improved, and the reasonability of the data is ensured. The data sorting processing can sort the real-time position data of the ship according to time or other sequences, provides an optional interface for processing the ship behavior data, and is convenient for other terminal users to obtain data resources according to different requirements. The data interpolation processing is to supplement missing points in the data, and the commonly used data interpolation methods include Lagrange interpolation and the like, and the quality of the processed data is improved through data difference processing.
Step S203, grouping the acquired real-time position data to obtain initial data of the ship behavior;
in the embodiment of the invention, after the real-time position data is acquired, in order to accurately judge the ship behavior of the designated ship, the real-time position data can be grouped according to the ship to which the real-time position data belongs, so that the original data of the designated ship can be obtained. Optionally, the data grouping may be implemented in various ways, for example, the acquired real-time position data includes a ship identification code of the AIS ship data, an aquatic mobile communication service identification code MMSI of a ship corresponding to the ship identification code, and the real-time position data belonging to the same ship identification code is identified by the MMSI; or grouping the fused batch numbers after fusion processing as unique identifiers.
Step S204, respectively calculating characteristic data of the ship behaviors according to the initial data; wherein the characteristic data of the ship behavior comprises: the sailing speed, sailing displacement and sailing direction of the ship are changed; the sailing displacement is the displacement generated by the current ship behavior relative to the initial ship behavior, and the sailing direction change is the direction change of the displacement.
In the embodiment of the invention, the obtained original data of the ship behavior is correspondingly calculated, namely the characteristic data of the ship behavior is extracted. It may be extraction of feature data that characterizes the behavior of the ship, for example, feature data such as ship's speed, displacement, direction of travel, and the like.
First, the original data of the ship behavior, such as characteristic parameters of the navigation speed, the navigation displacement, the navigation direction and the like, are initialized.
Then, according to the displacement generated by the current ship behavior relative to the initial ship behavior, the sailing displacement is obtained, and the direction change of the sailing displacement is the sailing direction change. The motion characteristics of the ship behavior can be accurately analyzed and evaluated by extracting the characteristic data, so that the characteristic data-based analysis statistics can be used as a reliable evaluation basis for the safe navigation and avoidance rules of the ship.
And S205, judging the characteristic data of the ship behavior based on the conditions of the anchoring behavior rule base, and judging the ship behavior as the anchoring behavior when the judgment result meets the conditions of the anchoring behavior rule base.
In the embodiment of the present invention, the anchoring behavior rule base may be a set of rules for determining the anchoring behavior of the ship, and the set may define the anchoring behavior by one or more rules, for example, perform qualitative comprehensive evaluation and determination on the feature data characterizing the ship behavior, or perform quantitative comprehensive evaluation and determination on the feature data based on the ship behavior, for example, determine the sailing speed, the sailing displacement, and the sailing direction change, respectively:
the navigation speed is less than a preset first threshold value;
the navigation displacement is smaller than a preset second threshold value;
the sailing direction changes to be continuous.
The values of the first threshold and the second threshold can be obtained by analyzing historical data of ship navigation or selecting abnormal values in a normal navigation track. By quantitative judgment of the characteristic data, the anchoring behavior of the ship can be accurately identified.
Because the real-time position data of the ship is acquired in real time, if the acquired data amount is insufficient, subsequent processing may be performed only on a single or a small amount of ship behaviors, the single or the small amount of ship behaviors are not universal, and if only the single or the small amount of ship behaviors are identified to be in an anchoring behavior, the statistical significance is not achieved, and the accuracy of subsequent analysis statistical results is affected. Therefore, in this step, in order to obtain more accurate data of the anchoring area, it is necessary to store the characteristic data of the anchoring behavior of the ship, and count a large number of characteristic data of the anchoring behavior so as to generate expected data of the anchoring area matching with the real sea area environment.
In the embodiment of the present invention, a statistical time may also be preset, and the anchor dropping behavior feature data may be stored according to the preset statistical time. And enough characteristic data of the anchoring behavior of the ship is ensured through presetting statistical time, so that accurate anchoring region data can be generated.
With further reference to fig. 3, a detailed flowchart is shown regarding step S102 and step S103, that is, after step S101, the step of analyzing and counting the anchoring behavior is performed in sequence according to an embodiment of the present application; and generating anchoring area data of the ship according to the analysis and statistics result.
In step S102, analyzing the statistical anchoring behavior may include the following steps shown in fig. 3:
step S301, analyzing the characteristic data of the anchoring behavior;
and judging to obtain the anchoring behavior of the ship according to the anchoring behavior rule base, and analyzing the anchoring behavior which may exist for many times or has longer anchoring behavior duration, thereby further extracting important influence factors for generating anchoring region data.
And step S302, counting the accumulated duration and anchoring times of the anchoring behavior.
For the statistics of the accumulated duration and the anchoring times of the anchoring behaviors, an analysis basis can be provided for determining the anchoring area, so that the accuracy of the anchoring area is improved.
Step 103, generating the data of the anchored area of the ship according to the result of the analysis statistics, which may include all or part of the following steps shown in fig. 3:
and S303, generating anchoring area data of the ship based on the accumulated duration and the anchoring times.
Step S304, which is optionally added in different embodiments, stores the anchoring area data of the ship in a format data or database mode. Based on the analysis and statistics results of the real-time anchoring behavior, the occurrence of shipping accidents can be effectively prevented, the output of real ship anchoring region data provides abundant data resources for other terminal users to know the shipping condition in time, and the effectiveness of ship safety management is improved.
It should be noted that while the operations of the method of the present invention are depicted in the drawings in a particular order, this does not require or imply that the operations must be performed in this particular order, or that all of the illustrated operations must be performed, to achieve desirable results. Rather, the steps depicted in the flowcharts may change the order of execution. For example, S101 and S102, after acquiring a certain amount of data of the anchoring behavior, S101 may continue to identify the anchoring behavior, and simultaneously execute steps S102 and S103. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions. For example, steps S201 and S204 may be omitted, and S201 and S202 may be combined into one step.
