Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The ship data can be used for representing track information of a ship, attachment information of the ship, voyage information of the ship, service states of a port and the like, and whether the ship has abnormal behaviors or not and the port busy state and the like can be analyzed based on the ship data.
However, the historical data of the ship is usually stored by the corresponding operation unit, and if the operation unit modifies the historical data of the ship, the authenticity of the data cannot be traced. If the historical data of the ship needs to be collected by the ship notarization relevant staff, a large amount of relevant data (such as relevant contract data) needs to be collected manually as evidence, and the evidence collection efficiency is reduced. For example, when a ship a unloads at a port a, a berth of the port a is damaged by collision, a berth operating unit is charged with recent berth service, and service loss caused by collision of the berth is so that unreasonable compensation is required for an operating unit corresponding to the ship a.
In view of the above, the present invention provides a ship data query method. Fig. 1 is a schematic flow chart of a ship data query method provided by the present invention, and as shown in fig. 1, the method includes the following steps:
and step 110, determining the identification information of the ship to be inquired.
Specifically, the ship to be queried refers to a ship needing to query data, and the purpose of querying may be to analyze a track of the ship based on the data of the ship, or to notarize the ship, or to analyze a port service state. The identification information of the ship to be queried is used for representing characteristic attribute information of the ship, such as a marine mobile identity (MMSI) of the ship, classification of the ship (such as a passenger ship, a cargo ship and the like), size of the ship and the like, and can be understood as that after the identification information of the ship to be queried is determined, the ship to be queried can be locked in a ship database or a plurality of ships with the same type can be screened out through the identification information of the ship to be queried, and then the plurality of ships with the same type are screened to determine the ship to be queried finally.
For example, the type of the ship to be queried is a marine mobile identification code, and the marine mobile identification code and the ship are in one-to-one correspondence, so that the corresponding ship can be accurately locked based on the marine mobile identification code; if the type of the ship to be queried is the size of the ship, the ship to be queried may correspond to a plurality of ships, so that the plurality of ships may be screened out based on the size of the ship, the query range is reduced, and then the ship to be queried may be determined from the plurality of ships.
and the data in the ship database is the data after block chain data storage of the data of the historical ship.
Specifically, in the ship database, after the identification information of the ship to be queried is determined based on the mapping relationship between the identification information of the ship and the data of the ship, the corresponding data can be quickly acquired from the ship database. The data of the ship can be used for representing track information of the ship, attachment information of the ship, port service information and the like, and the behavior track of the ship can be analyzed based on the data of the ship to judge whether the ship has abnormal behaviors; and the idle state of the port berth can be analyzed to judge whether the port berth is busy or not.
It should be noted that the data in the ship database is obtained by performing block chain data storage on the original data of the historical ship, and the block chain data storage is obtained by storing the original data of the ship in a block chain, so that the purposes of tamper resistance, traceability and trustable data source are achieved. The original data of the ship can refer to ship data acquired by an Automatic Identification System (AIS) of the ship in real time, namely the data can be stored in a block chain after the AIS acquires the data of the ship in real time, and the data on the block chain is tamper-proof, so that the data can be compared with corresponding data on the block chain if the authenticity of the inquired data is doubted, if the data is consistent, the data is proved to be real and reliable, and if the data is inconsistent, the data is proved to be possibly tampered, and the authenticity of the data is doubted. Therefore, the method and the device for verifying the ship data have the advantages that the original data of the historical ship are subjected to block chain data evidence storage, authenticity of the ship data can be rapidly determined through comparison with the data stored on the block chain, and the problem that evidence collection efficiency is low due to the fact that a large amount of data information needs to be collected for evidence collection in a traditional method is solved. In addition, the method for determining the authenticity of the ship data by comparing the ship data with the data stored in the block chain is simple and easy to operate, and the method does not need comparison personnel to have professional basic knowledge and technical threshold, so that the training cost of the professional personnel is saved. In the traditional method, a large amount of data information is collected to obtain evidence, so that evidence obtaining personnel are required to have relevant professional knowledge, and the labor cost is increased.
In addition, after the block chain data of the original data of the historical ship is stored, when other personnel need to inquire the data of the ship, the data can be inquired through the block chain, so that data sharing is realized, the problem that the authenticity of the data cannot be traced due to the fact that the data of each ship can only be inquired by a corresponding operation unit in the traditional method and cannot be shared is solved, and decentralized data management is realized.
According to the ship data query method provided by the embodiment of the invention, based on the mapping relation between the identification information of the ship and the data of the ship, the data of the ship to be queried can be quickly determined in the ship database, and the data in the ship database is the data after the evidence is stored through the block chain, so that the authenticity of the ship data can be traced, and the problem of low evidence collection efficiency caused by the fact that a large amount of related data needs to be collected for evidence collection in the traditional method is solved.
Based on the above embodiments, the data of the vessel includes trajectory data, berthing data, voyage data, and analysis data.
Specifically, the track data includes dynamic data of the ship, such as dynamic information of the MMSI number of the ship, message sending time, longitude, latitude, navigational speed, heading, ship heading, navigational state, and the like, the track data of the ship can be used for representing a traveling track of the ship, the heading, navigational speed, and the like of the ship can be predicted based on the track data of the ship, and thus, collision between ship tracks can be avoided.
The berthing data is used for representing arrival and departure data of the ship at the port, and the berthing data can be obtained based on the ship track data and port area data. In the method, index parameters such as port throughput and the like used for reflecting port operation capacity and efficiency indexes can be analyzed based on the ship attachment data.
Since the ship's attachment data is single-ended, it is reflected that the ship arrives at the port, for example, the ship's attachment data may reflect the ship's arrival at the destination port a, but may not reflect the ship's initial port data. Therefore, in order to analyze the behavior of the ship more comprehensively, the embodiment of the invention also needs to acquire the ship voyage data for representing the navigation information of the ship from the starting port to the destination port. Wherein the voyage data of the vessel can be determined based on the berthing data of the vessel.
The analysis data comprises statistical data of the ship and multi-dimensional data of the ship, the statistical data of the ship is obtained based on track data of the ship, attachment data of the ship and voyage data statistics of the ship, and the statistical data can comprise data such as ship activeness, port attachment amount and airline business busyness. Different from the statistical data of the ship, the multi-dimensional data of the ship is not obtained by simply counting the track data of the ship, the attachment data of the ship and the voyage data of the ship, but is obtained by analyzing and mining the behavior of the ship based on the track data of the ship, the attachment data of the ship, the voyage data of the ship and the statistical data of the ship, and is used for representing the behavior type of the ship. The multi-dimensional data of the vessel may include: specifying the liveness of the vessel within a defined period; the area A is passed at a specified time; staying in the area A for more than N days within a specified time period; the system is attached to the port A at a specified time; anchoring operation is carried out at an anchor land A at a designated time; in a specified large time period, no port-leading behavior exists for a long time; port A arrives a limited period of time. Therefore, based on the analysis data of the ship, the specific behavior of the ship can be analyzed, so that the ship can be controlled, notarized and the like in the follow-up process.
Based on any one of the above embodiments, the ship database is constructed based on the following steps:
determining the track data of each historical ship based on the AIS message data, and performing block chain data storage and verification on the track data of each historical ship;
determining the attachment data of each historical ship based on port region data and track data of each historical ship, and performing block chain data evidence storage on the attachment data of each historical ship;
determining the voyage data of each historical ship based on the attachment data of each historical ship, and performing block chain data storage on the voyage data of each historical ship;
determining analysis data of each historical ship based on the track data of each historical ship, the attachment data of each historical ship and the voyage data of each historical ship;
and constructing a ship database based on the type of each historical ship and the mapping relation among the track data of each historical ship, the attachment data of each historical ship, the voyage data of each historical ship and the analysis data of each historical ship.
Specifically, the track data of the historical ship may refer to historical track data of a large number of sample ships acquired through the AIS message data, the historical track data includes dynamic data of the ship, such as dynamic information of the MMSI number of the ship, message sending time, longitude, latitude, speed, heading, navigation state, and the like, and the historical track data may be used to represent a driving track of the historical ship. After the track data of each historical ship is determined, block chain data storage is carried out on the track data of each historical ship, so that the track data of the historical ships stored on the block chain can be used as a certificate, and the authenticity of the currently inquired track data of the ships is judged.
The historical ship attachment data is used for representing the arrival and departure data of the ship at the port, and the attachment data can be obtained based on the ship track data and port area data. In the method, index parameters such as port throughput and the like used for reflecting port operation capacity and efficiency indexes can be analyzed based on the ship attachment data. After the attachment data of each historical ship is determined, block chain data storage is carried out on the attachment data of each historical ship, so that the attachment data of the historical ships stored on the block chain can be used as a certificate, and the authenticity of the currently inquired attachment data of the ships is judged.
Since the historical ship attachment data is single-ended, the ship arrival and departure of the port are used for reflecting, and the initial port data of the ship cannot be reflected. Therefore, in order to analyze the behavior of the historical ship more comprehensively, the embodiment of the invention also needs to acquire the historical ship voyage data used for representing the navigation information of the historical ship from the starting port to the destination port. Wherein the voyage data of the historical vessel may be determined based on the berthing data of the vessel. After the voyage data of each historical ship is determined, block chain data storage is carried out on the voyage data of each historical ship, so that the voyage data of the historical ships stored on the block chain can be used as a certificate, and the authenticity of the currently inquired voyage data of the ships is judged.
The method comprises the steps that analysis data of each historical ship can be determined based on track data of each historical ship, attachment data of each historical ship and voyage data of each historical ship, the analysis data of each historical ship comprises statistical data of the historical ships and multi-dimensional data of the historical ships, the statistical data of the historical ships are obtained based on track data of the historical ships, voyage data of the historical ships and voyage data of the historical ships, and the statistical data can comprise data such as historical ship liveness, port attachment amount and airline business busyness. Different from the statistical data of the historical ships, the multi-dimensional data of the historical ships are not obtained by simply counting the track data of the historical ships, the voyage data of the historical ships and the voyage data of the historical ships, but are obtained by analyzing and mining the behaviors of the historical ships based on the track data of the historical ships, the voyage data of the historical ships and the statistical data of the historical ships, and are used for representing the behavior types of the historical ships. The multi-dimensional data of the historical vessel may include: specifying the liveness of the vessel within a defined period; the area A is passed at a specified time; staying in the area A for more than N days within a specified time period; the system is attached to the port A at a specified time; anchoring operation is carried out at an anchor land A at a designated time; in a specified large time period, no port-leading behavior exists for a long time; port A arrives a limited period of time. Further, since the analysis data of the historical ships is determined based on the trajectory data of each historical ship, the attachment data of each historical ship, and the voyage data of each historical ship, and the trajectory data of each historical ship, the attachment data of each historical ship, and the voyage data of each historical ship are data after the block chain storage is verified, the authenticity of the analysis data of the historical ships can be verified even after the authenticity of the trajectory data of each historical ship, the attachment data of each historical ship, and the voyage data of each historical ship is verified.
And then, constructing a ship database based on the type of each historical ship and the mapping relation among the track data of each historical ship, the attachment data of each historical ship, the voyage data of each historical ship and the analysis data of each historical ship, so that the corresponding ship data can be quickly inquired in the ship database based on the identification information of the ship.
As shown in fig. 2, based on the AIS message data, trajectory data of the ship is obtained, based on the trajectory data and the port dictionary, attachment data can be obtained, based on the attachment data, voyage data can be obtained, and the trajectory data, the attachment data, and the voyage data are counted and analyzed, so that analysis data of the ship can be obtained.

and carrying out data cleaning on the initial track data to obtain the track data of each historical ship.
Specifically, the AIS message data is analyzed to generate ship dynamic data, static data and voyage information data, wherein the ship dynamic data is initial track data of a ship. Since invalid data, noise data and the like may exist in the initial trajectory data, in order to analyze the behavior of the ship more accurately, data cleaning (such as denoising processing, rarefying processing and the like) needs to be performed on the initial trajectory data to obtain trajectory data of each historical ship, and the trajectory data is used for analyzing the trajectory state, the trajectory rule and the like of the ship.
Based on any embodiment, after determining the data of the ship to be queried, the method further includes:

After the display mode is determined, the data of the ship to be inquired is displayed in the corresponding display mode, so that the corresponding data can be flexibly displayed according to different types of ships.
Based on any embodiment, after determining the data of the ship to be queried, the method further includes:
and determining notarization data of the ship to be inquired based on the data of the ship to be inquired and the data of the notarization stored on the block chain.
Specifically, the notarization data of the ship to be queried requires that the data is real, so that the data of the ship to be queried, which is determined in the ship database, needs to be compared with the data of the notarization stored on the block, and if the data of the ship to be queried is consistent with the data of the notarization stored on the block, the data of the ship to be queried is real and can be used as the notarization data; if the data of the ship to be inquired is inconsistent with the data of the ship to be inquired, the data of the ship to be inquired is possibly tampered and cannot be used as notarization data.
