[0002] In related technologies, ship port sequences are generally obtained through ship owners. However, there are many ship owners in the world, and there are many customary port sequences for different ship types and routes. The customary port sequences of different ships may not be displayed on the official website of the shipping company. For ordinary users, the barrier to obtaining information on ship port sequences is relatively large. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention proposes a method for acquiring ship port sequence information.

[0005] The second aspect of the present invention provides a system for acquiring ship port sequence information.

[0006] A third aspect of the present invention provides an electronic device.

[0007] A fourth aspect of the present invention provides a storage medium.

[0008] In view of this, according to a first aspect of the present invention, a method for obtaining ship port sequence information is proposed, comprising: obtaining a port call record table of a ship's history, wherein the port call record table includes a first port sequence, and the first port sequence includes a plurality of sequentially arranged port names; generating a plurality of second port sequences according to the first port sequence, wherein the second port sequence is a port sequence composed of a plurality of sequentially arranged port names in the first port sequence moved according to a preset order, and each second port sequence corresponds to a different preset order; determining whether each second port sequence is related to the first port sequence; when the second port sequence is related to the first port sequence, determining the preset order corresponding to the second port sequence; obtaining a preset order of port names in the first port sequence in order, and forming a third port sequence; and using the third port sequence and the port information corresponding to the plurality of port names in the third port sequence as the ship port sequence information.

[0009] The method for obtaining the port sequence information of a ship provided by the present invention mainly comprises: firstly obtaining a port call record table of the ship's history, wherein the port call record table includes a first port sequence, and a plurality of port names arranged in a preset order in the first port sequence may be sorted according to the arrival and departure time of the ship, and the port names in the first port sequence may be repeated. That is to say, the port call record table of the ship's history records the ports that the ship has docked during operation in the past period of time. After obtaining the port call record table of the ship's history, a plurality of second port sequences are generated according to the first port sequence, wherein the second port sequence is a port sequence composed of a plurality of sequentially arranged port names in the first port sequence after being moved according to a preset order, and the preset order corresponding to each second port sequence is different, that is, the first port sequence may be processed by a moving window technology to obtain a plurality of second port sequences, and the preset order may range from 1st to 30th by way of example, and the Nth port in the first port sequence is the same as the NKth port in the second port sequence, wherein K is the preset order corresponding to the second port sequence. After obtaining multiple second port sequences, determine whether each second port sequence is related to the first port sequence, that is, determine whether the port names in the same row of the second port sequence and the first port sequence are the same. If the port names in the same row of the second port sequence and the first port sequence are the same, it means that the second port sequence is related to the first port sequence; if the port names in the same row of the second port sequence and the first port sequence are different, it means that the second port sequence is not related to the first port sequence. Based on the existence of a second port sequence related to the first port sequence in multiple second port sequences, determine the preset order corresponding to the second port sequence; if there are multiple second port sequences related to the first port sequence, determine the preset order corresponding to each second port sequence related to the first port sequence, and then calculate the least common multiple between the multiple preset orders. After obtaining the preset order or the least common multiple, obtain the preset order or the least common multiple port names in the first port sequence in sequence, and form a third port sequence with these port names in the order of the first port sequence. Finally, the third port sequence and the port information corresponding to the multiple port names in the third port sequence are used as the ship port sequence information of the ship.In the present invention, a historical port call record table of a ship is first obtained, and then a first port sequence is obtained according to the port call record table, and then a moving window technology is used to generate a plurality of second port sequences after moving windows of different preset orders according to the first port sequence, and then it is determined whether each second port sequence is related to the first port sequence, and then when the second port sequence is related to the first port sequence, the preset order of the second port sequence related to the first port sequence is determined, and finally, the preset order of port names are obtained in sequence in the first port sequence to form a third port sequence, and finally, the ship's port sequence information of the ship is obtained according to the port names in the third port sequence and the corresponding port information, thereby realizing the acquisition of the ship's port sequence information and solving the problem of large barriers to the acquisition of ship port sequence information in related technologies.

[0010] The method for obtaining the above-mentioned ship port sequence information according to the present invention may also have the following technical features: In some technical solutions, optionally, the steps of separately determining whether each second port sequence is related to the first port sequence include: separately calculating the first distance value between two ports located at the same position in the second port sequence and the first port sequence; mapping the first distance value to a preset interval to obtain a second distance value; separately calculating the average value between multiple second distance values ​​corresponding to each second port sequence; and determining whether the second port sequence is related to the first port sequence based on the average value.

[0011] In the technical solution, the step of determining whether each second port sequence is related to the first port sequence includes: first, respectively calculating the first distance value between two ports located at the same position in the second port sequence and the first port sequence. Since the port is not a number, it cannot be added or subtracted, and the correlation cannot be calculated, so it becomes the value of the distance between the ports. After obtaining the first distance value, since the distance value is too large, the correlation cannot be accurately determined, so the first distance value can be mapped to a preset interval to obtain a second distance value, wherein the preset interval can be a 0-1 interval, the smaller the first distance value between the two ports, the closer the second distance value is to 1, and the larger the first distance value between the two ports, the closer the second distance value is to 0. After obtaining the second distance values ​​corresponding to all the port names in each second port sequence, respectively calculate the average value between the multiple second distance values ​​corresponding to each second port sequence, and finally determine whether each port sequence is related to the first port sequence according to the average value corresponding to each second port sequence. In the present application, the first distance value between the ports located at the same position between the second port sequence and the first port sequence is calculated, and then the first distance value is mapped to the 0-1 interval through a function, and then the average value of the 0-1 interval value obtained for each second port sequence is calculated, and finally, whether the second port sequence is related to the first port sequence is determined based on the average value, thereby realizing the calculation of whether the first port sequence and the second port sequence are related.

[0012] In some technical solutions, optionally, the step of determining whether the second port sequence is related to the first port sequence based on the average value includes: determining the maximum value among multiple average values; comparing the maximum value with a preset threshold; determining that the second port sequence corresponding to the maximum value is related to the first port sequence based on the maximum value being greater than or equal to the preset threshold; and determining that the ship has no habitual port sequence based on the maximum value being less than the preset threshold.

[0013] In the technical solution, the step of determining whether the second port sequence is related to the first port sequence based on the average value includes: after obtaining the average value corresponding to each second port sequence, comparing multiple average values ​​to determine the maximum value therein, and then comparing the maximum value with a preset threshold value. If the maximum value is greater than or equal to the preset threshold value, it means that the second port sequence corresponding to the maximum value is related to the first port sequence; if the maximum value is less than the preset value, it means that any second port sequence among the multiple second port sequences is not related to the first port sequence, and further indicates that the ship has no habitual port sequence, that is, the ship does not have a fixed port of call.

[0014] In some technical solutions, optionally, the step of obtaining a historical port call record of a ship includes: obtaining first data information from a ship automatic identification system of the ship; obtaining port location information; and obtaining a port call record based on the first data information and the port location information, wherein the port call record includes ship identity information, port information, and arrival and departure times of the ship.

[0015] In this technical solution, the step of obtaining the historical port call record table of the ship includes: first obtaining the first data information in the ship's Automatic Identification System (AIS), namely the ship's AIS data, and then obtaining the location information of each port. Finally, the historical call record data of the ship, namely the port call record table, is generated according to the AIS data and the port location information, wherein the port call record table includes the following fields: ship identity information. The port information of the call and the arrival and departure time of the ship when it is docked at the port. The historical port call record table of the ship is generated through the AIS data and the port location information, thereby ensuring the accuracy of the port information in the port call record table.

[0016] According to a second aspect of the present invention, a system for acquiring ship port sequence information is proposed, comprising: a first acquisition module, the first acquisition module is used to acquire a port call record table of a ship's history, wherein the port call record table includes a first port sequence, and the first port sequence includes a plurality of sequentially arranged port names; a first generation module, the first generation module is used to generate a plurality of second port sequences according to the first port sequence, wherein the second port sequence is a port sequence composed of a plurality of sequentially arranged port names in the first port sequence after being moved according to a preset order, and the preset order corresponding to each second port sequence is different; a first determination module, the first determination module is used to determine whether each second port sequence is related to the first port sequence; a first processing module, the first processing module is used to determine the preset order corresponding to the second port sequence when the second port sequence is related to the first port sequence; a second processing module, the second processing module is used to sequentially acquire a preset order of port names in the first port sequence and form a third port sequence; a third processing module, the third processing module is used to use the third port sequence and the port information corresponding to the plurality of port names in the third port sequence as the ship port sequence information.

[0017] The system for acquiring the ship port sequence information provided by the present invention mainly includes: a first acquisition module, a first generation module, a first determination module, a first processing module, a second processing module and a third processing module. The first acquisition module can acquire the port call record table of the ship's history, wherein the port call record table includes a first port sequence, and the names of multiple ports arranged in a preset order in the first port sequence can be sorted according to the arrival and departure time of the ship, and the port names in the first port sequence can be repeated. That is to say, the port call record table of the ship's history records the ports that the ship has docked during its operation in the past period of time. After obtaining the port call record table of the ship's history, the first generation module generates multiple second port sequences according to the first port sequence, wherein the second port sequence is a port sequence composed of multiple sequentially arranged port names in the first port sequence after being moved according to a preset order, and the preset order corresponding to each second port sequence is different, that is, the first port sequence can be processed by a moving window technology to obtain multiple second port sequences. Exemplarily, the preset order range can be 1 to 30, and the Nth port in the first port sequence is the same as the NKth port in the second port sequence, wherein K is the preset order corresponding to the second port sequence. After obtaining multiple second port sequences, the first determination module determines whether each second port sequence is related to the first port sequence, that is, determines whether the port names in the same row of the second port sequence and the first port sequence are the same. If the port names in the same row of the second port sequence and the first port sequence are the same, it means that the second port sequence is related to the first port sequence; if the port names in the same row of the second port sequence and the first port sequence are different, it means that the second port sequence is not related to the first port sequence. The first processing module is used to determine the preset order corresponding to the second port sequence based on the presence of a second port sequence related to the first port sequence in multiple second port sequences; if there are multiple second port sequences related to the first port sequence, the preset order corresponding to each second port sequence related to the first port sequence is determined, and then the least common multiple between the multiple preset orders is calculated. After obtaining the preset order or the least common multiple, the second processing module sequentially obtains the preset order or the least common multiple port names in the first port sequence, and composes these port names into a third port sequence according to the order in the first port sequence. Finally, the third processing module uses the third port sequence and the port information corresponding to the multiple port names in the third port sequence as the ship port sequence information of the ship.In the present invention, a historical port call record table of a ship is first obtained, and then a first port sequence is obtained according to the port call record table, and then a moving window technology is used to generate a plurality of second port sequences after moving windows of different preset orders according to the first port sequence, and then it is determined whether each second port sequence is related to the first port sequence, and then when the second port sequence is related to the first port sequence, the preset order of the second port sequence related to the first port sequence is determined, and finally, the preset order of port names are obtained in sequence in the first port sequence to form a third port sequence, and finally, the ship's port sequence information of the ship is obtained according to the port names in the third port sequence and the corresponding port information, thereby realizing the acquisition of the ship's port sequence information and solving the problem of large barriers to the acquisition of ship port sequence information in related technologies.

Among them, the first calculation module calculates the first distance value between the two ports located at the same position in the second port sequence and the first port sequence respectively. Since the port is not a number, it cannot be added or subtracted, and the correlation cannot be calculated, so it becomes the value of the distance between the ports. After obtaining the first distance value, since the distance value is too large, the correlation cannot be accurately judged, so the mapping module can map the first distance value to a preset interval to obtain a second distance value, wherein the preset interval can be a 0-1 interval, the smaller the first distance value between the two ports, the closer the second distance value is to 1, and the larger the first distance value between the two ports, the closer the second distance value is to 0.

In the present application, the first distance value between the ports located at the same position between the second port sequence and the first port sequence is calculated, and then the first distance value is mapped to the 0-1 interval through a function, and then the average value of the 0-1 interval value obtained for each second port sequence is calculated, and finally, whether the second port sequence is related to the first port sequence is determined based on the average value, thereby realizing the calculation of whether the first port sequence and the second port sequence are related.

That is to say, the port call record table of the ship's history records the ports that the ship has docked during operation in the past period of time. After obtaining the port call record table of the ship's history, a plurality of second port sequences are generated according to the first port sequence, wherein the second port sequence is a port sequence composed of a plurality of sequentially arranged port names in the first port sequence after being moved according to a preset order, and the preset order corresponding to each second port sequence is different, that is, the first port sequence may be processed by a moving window technology to obtain a plurality of second port sequences, and the preset order may range from 1 to 30, and the Nth port in the first port sequence is the same as the NKth port in the second port sequence, wherein K is the preset order corresponding to the second port sequence.

After obtaining multiple second port sequences, determine whether each second port sequence is related to the first port sequence, that is, determine whether the port names in the same row of the second port sequence and the first port sequence are the same. If the port names in the same row of the second port sequence and the first port sequence are the same, it means that the second port sequence is related to the first port sequence; if the port names in the same row of the second port sequence and the first port sequence are different, it means that the second port sequence is not related to the first port sequence. Based on the existence of a second port sequence related to the first port sequence in multiple second port sequences, the preset order corresponding to the second port sequence is determined; if there are multiple second port sequences related to the first port sequence, the preset order corresponding to each second port sequence related to the first port sequence is determined, and then the lowest common multiple between the multiple preset orders is calculated.

Since the port is not a number, it cannot be added or subtracted, and the correlation cannot be calculated, so it becomes the value of the distance between the ports. After obtaining the first distance value, since the distance value is too large, the correlation cannot be accurately determined, so the first distance value can be mapped to a preset interval to obtain a second distance value, wherein the preset interval can be a 0-1 interval, the smaller the first distance value between the two ports, the closer the second distance value is to 1, and the larger the first distance value between the two ports, the closer the second distance value is to 0. After obtaining the second distance values ​​corresponding to all the port names in each second port sequence, respectively calculate the average value between the multiple second distance values ​​corresponding to each second port sequence, and finally determine whether each port sequence is related to the first port sequence according to the average value corresponding to each second port sequence. In the present application, the first distance value between the ports located at the same position between the second port sequence and the first port sequence is calculated, and then the first distance value is mapped to the 0-1 interval through a function, and then the average value of the value in the 0-1 interval obtained for each second port sequence is calculated, and finally, whether the second port sequence is related to the first port sequence is determined based on the average value, thereby realizing the determination of whether the first port sequence and the second port sequence are related.

[0041] In this embodiment, the AIS data and port location information are first used to generate the ship's historical call record data, such as Figure 6 As shown, the docking record data includes the following fields: ship identity information, docked port information and docked arrival and departure time. Then generate new docking sequences after moving windows of order 1 to 30, that is, add a data column to the original docking record table, which is recorded as the ports of moving windows of order 1 to 30. The information in this column is consistent with the original docked port information, but the port in the nth row is the port in the nkth row, and k is the order of movement. Then calculate the correlation between the new sequence and the original sequence. Since the port is not a number, it cannot be added or subtracted, and the correlation cannot be calculated, so it becomes the value of the distance between ports, and is mapped to the interval of 0-1 through a function, such as Figure 7 As shown. Then determine the optimal moving window size for a single ship, that is, calculate the average value of the 0-1 interval obtained for each ship at the 1st to 30th order. The order with the largest mean value and exceeding the data cleaning threshold is the number of ports in the customary port sequence port string. If the ship with the largest mean value but does not exceed the data cleaning threshold, it is judged as non-liner transportation (there is no periodicity and no customary port sequence). Finally, mine the customary port sequence data, that is, for ships determined to have a customary port sequence, take the port string in the moving window as the customary port sequence. For example, Figure 7 As shown, it can be seen that the correlations at lags of 4, 8, 12, 16, 20, 24, and 28 are the highest. Therefore, when the scores are the same, the lowest common multiple of 4 is used, and the resulting combined port order is (B, C, B, A).

[0042] Figure 8 A schematic block diagram of a system for acquiring ship port sequence information according to an embodiment of the present invention is shown; wherein the system 80 for acquiring ship port sequence information comprises: A first acquisition module 802 is used to acquire a port call record table of the ship's history, wherein the port call record table includes a first port sequence, and the first port sequence includes a plurality of sequentially arranged port names; A first generating module 804 is used to generate a plurality of second port sequences according to the first port sequence, wherein the second port sequence is a port sequence formed by moving a plurality of sequentially arranged port names in the first port sequence according to a preset order, and each second port sequence corresponds to a different preset order; A first determination module 806, configured to respectively determine whether each second port sequence is related to the first port sequence; A first processing module 808, for determining a preset order corresponding to the second port sequence if the second port sequence is related to the first port sequence; The second processing module 810 is used to sequentially obtain a preset number of port names in the first port sequence and form a third port sequence; The third processing module 812 is used to use the third port sequence and the port information corresponding to the multiple port names in the third port sequence as the ship port sequence information.

[0043] The system 80 for acquiring the ship port sequence information provided by the present invention mainly includes: a first acquisition module 802, a first generation module 804, a first determination module 806, a first processing module 808, a second processing module 810 and a third processing module 812. The first acquisition module 802 can acquire the port call record table of the ship's history, wherein the port call record table includes a first port sequence, and the names of multiple ports arranged in a preset order in the first port sequence can be sorted according to the arrival and departure time of the ship, and the port names in the first port sequence can be repeated. That is to say, the port call record table of the ship's history records the ports that the ship has docked during its operation in the past period of time. After obtaining the port call record table of the ship's history, the first generation module 804 generates a plurality of second port sequences according to the first port sequence, wherein the second port sequence is a port sequence composed of a plurality of sequentially arranged port names in the first port sequence after being moved according to a preset order, and each second port sequence corresponds to a different preset order, that is, the first port sequence can be processed by a moving window technique to obtain a plurality of second port sequences, and the preset order can range from 1 to 30, and the Nth port in the first port sequence is the same as the NKth port in the second port sequence, wherein K is the preset order corresponding to the second port sequence. After obtaining a plurality of second port sequences, the first determination module 806 determines whether each second port sequence is related to the first port sequence, that is, determines whether the port names in the same row of the second port sequence and the first port sequence are the same. If the port names in the same row of the second port sequence and the first port sequence are the same, it means that the second port sequence is related to the first port sequence; if the port names in the same row of the second port sequence and the first port sequence are different, it means that the second port sequence is not related to the first port sequence. The first processing module 808 is used to determine the preset order corresponding to the second port sequence based on the presence of a second port sequence related to the first port sequence in multiple second port sequences; if there are multiple second port sequences related to the first port sequence, the preset order corresponding to each second port sequence related to the first port sequence is determined, and then the least common multiple between the multiple preset orders is calculated. After obtaining the preset order or the least common multiple, the second processing module 810 sequentially obtains the preset order or the least common multiple port names in the first port sequence, and composes these port names into a third port sequence according to the order in the first port sequence. Finally, the third processing module 812 uses the third port sequence and the port information corresponding to the multiple port names in the third port sequence as the ship port sequence information of the ship.In the present invention, a historical port call record table of a ship is first obtained, and then a first port sequence is obtained according to the port call record table, and then a moving window technology is used to generate a plurality of second port sequences after moving windows of different preset orders according to the first port sequence, and then it is determined whether each second port sequence is related to the first port sequence, and then when the second port sequence is related to the first port sequence, the preset order of the second port sequence related to the first port sequence is determined, and finally, the preset order of port names are obtained in sequence in the first port sequence to form a third port sequence, and finally, the ship's port sequence information of the ship is obtained according to the port names in the third port sequence and the corresponding port information, thereby realizing the acquisition of the ship's port sequence information and solving the problem of large barriers to the acquisition of ship port sequence information in related technologies.

Since the port is not a number, it cannot be added or subtracted, and the correlation cannot be calculated, so it becomes the value of the distance between the ports. After obtaining the first distance value, since the distance value is too large, the correlation cannot be accurately determined, so the mapping module 8064 can map the first distance value to a preset interval to obtain a second distance value, wherein the preset interval can be a 0-1 interval, the smaller the first distance value between the two ports, the closer the second distance value is to 1, and the larger the first distance value between the two ports, the closer the second distance value is to 0. After obtaining the second distance values ​​corresponding to all the port names in each second port sequence, the second calculation module 8066 calculates the average value between the multiple second distance values ​​corresponding to each second port sequence respectively, and finally the fourth processing module 8068 determines whether each port sequence is related to the first port sequence according to the average value corresponding to each second port sequence. In the present application, the first distance value between the ports located at the same position between the second port sequence and the first port sequence is calculated, and then the first distance value is mapped to the 0-1 interval through a function, and then the average value of the 0-1 interval value obtained for each second port sequence is calculated, and finally, whether the second port sequence is related to the first port sequence is determined based on the average value, thereby realizing the calculation of whether the first port sequence and the second port sequence are related.
