Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent operation of ship lock, in particular to a ship lock passing data determination method and device based on real-time ship position. BACKGROUND

[0002] In inland waterway transportation, as an important transportation hub, the ship lock plays an important role in connecting water systems and improving navigation conditions. However, the ship lock cannot be continuously passed through, and in busy navigation sections, the ship lock often becomes a bottleneck in the navigation channel, affecting the navigation efficiency of the entire navigation system. Due to factors such as infrastructure conditions, operation and management, the passing efficiency of most ship locks in China is low, but the operation cost is high. Using information means (for example, by obtaining ship lock passing related data, using digital technology and intelligent algorithms for analysis and mining) can improve the passing efficiency of the ship lock and reduce the operation cost. With the popularization of AIS, Beidou, radar and other ship positioning equipment, the number of ships equipped with positioning equipment has increased significantly. A large amount of ship position data contains a lot of important information. By calculating the real-time position of the ship and the ship lock area data, detailed ship lock passing data can be obtained for in-depth analysis and mining. The bottleneck of the ship lock system can be found, the process can be continuously optimized, and the ship lock passing efficiency, port competitiveness and service level can be improved. This has extremely important significance for realizing efficient use of resources, improving operation efficiency, reducing cost, improving service and promoting development.

It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from here.

[0048] Figure 1 is a flow chart of an optional ship lock data determination method based on real-time ship position according to an embodiment of the present application, as shown in Figure 1 The method comprises the following steps:

[0049] In step S101, real-time position data of each ship is collected, and the real-time position data is packaged according to a preset data format to obtain ship position data corresponding to each ship.

[0050] In step S102, area information of each ship lock is obtained to obtain ship lock area data.

[0051] In step S103, the relationship between each ship and the ship lock is determined based on the ship lock area data and the ship position data, with each ship as a grouping information column.

[0052] In step S104, ship lock data is determined based on the relationship between each ship and the ship lock, with each ship lock as a grouping information column.

[0053] Through the above steps, the real-time position data of each ship is first collected, and the real-time position data is packaged according to a preset data format to obtain ship position data corresponding to each ship. Then, the area information of each ship lock is obtained to obtain ship lock area data. Then, the relationship between each ship and the ship lock is determined based on the ship lock area data and the ship position data, with each ship as a grouping information column. Finally, ship lock data is determined based on the relationship between each ship and the ship lock, with each ship lock as a grouping information column.

[0054] In the embodiment of the present application, the complete navigation data and position information of each ship can be obtained by collecting real-time position data of the ship and packaging the data format. The relative position relationship between each ship and the ship lock during the ship passing through the lock can be accurately determined based on the ship lock area data and the ship position data, that is, whether the ship passing through the lock is smooth can be determined. Then, the ship lock data in the ship lock is calculated based on the position relationship between the ship and the ship lock and the ship position data, realizing efficient use of ship lock related data, and solving the technical problem of low utilization rate of ship related data caused by the inability to calculate ship lock data in the related art.

[0055] The embodiment of the present application will be described in detail below in combination with the above steps.

[0056] In the embodiment of the present application, the real-time position data of the ship and the navigation environment information in the ship lock area are utilized, and the process data and detailed result data of the ship passing through the lock are accurately calculated by the method of stream computing. In the method, the big data real-time stream processing technology Flink is used for program calculation, the Kafka message queue is used for data flow between steps, and the Redis is used as the cache for data transmission in the calculation process.

[0057] In step S101, the real-time position data of each ship is collected, and the real-time position data is packaged according to a preset data format to obtain ship position data corresponding to each ship.

[0058] It should be noted that the preset data format includes but is not limited to: ship unique identifier, ship name, ship type, ship longitude, ship latitude, data source (AIS, Beidou, radar, fusion signal), time point, etc.

[0059] It should be noted that the packaged data also needs to be preprocessed, mainly including: data verification, data cleaning, deduplication, parsing, etc. To avoid data loss, the ship real-time position data should be collected as quickly and comprehensively as possible when collecting the data for the first time.

[0060] In step S102, the area information of each ship lock is obtained to obtain ship lock area data.

[0061] Optionally, step S102 includes: obtaining N point information of each ship lock to obtain total ship lock area information, wherein the point information is used to locate the area range of the ship lock, N is an integer greater than or equal to 3; obtaining an uplink waiting lock area, a lock chamber and a downlink waiting lock area in each ship lock within the ship lock area to obtain a ship lock sub-area set; determining the ship lock area data based on the total ship lock area information and the ship lock sub-area set.

Figure 4 It should be noted that the point information can be longitude and latitude data or other positioning data. The point information of each area or sub-area can be connected in a certain order to form a polygon (shown by a dashed line) with a certain area. Figure 4 It should be noted that the polygons corresponding to the sub-areas cannot intersect, and the total area and the sub-areas form a containing relationship.

[0063] In step S103, the relationship between each ship and the ship lock is determined based on the ship lock area data and the ship position data, and each ship is taken as a grouping information column.

[0064] It should be noted that the ship and ship lock relationship information at least includes: ship real-time position data, ship information, ship lock information, and ship state information, wherein the ship state information includes: just entering the ship lock, being in the ship lock all the time, just leaving the ship lock, and the ship not entering the ship lock will be ignored.

[0065] Optionally, the step S103 comprises: calling the ship information of the current ship corresponding to the ship position data and the ship lock basic information corresponding to the ship lock area data; judging whether the ship information of the current ship has been cached; if the ship information of the current ship has not been cached, caching the ship information of the current ship to the target cache space; if the ship information of the current ship has been cached, judging whether the ship lock basic information has been cached; if the ship lock basic information has not been cached, judging whether the current ship is located in any ship lock based on the ship lock basic information and the ship lock area data; if the current ship is not located in any ship lock, returning to wait for the position data of the next ship; if the current ship is located in the target ship lock, defining the state information of the current ship as the ship just entering the ship lock; caching the ship lock information of the target ship lock entered by the current ship; and generating the ship and ship lock relationship based on the ship information of the current ship, the ship lock information of the target ship lock entered by the current ship, and the state information, taking each ship as a grouping information column.

[0066] It should be noted that in the embodiment, after completing a ship lock passing period (at least one ship passing through the ship lock once), the related results are calculated and stored, and the related cache information of the ship lock passing this time is deleted.

[0067] It should be noted that in the embodiment, the ship just entering the ship lock area is monitored, and the historical passing cache information of the ship is deleted. Optionally, after judging whether the ship lock basic information has been cached, it further comprises: if the ship lock basic information has been cached, judging whether the current ship is still in the cached ship lock; if the current ship is still in the cached ship lock, defining the state information of the current ship as the ship being in the ship lock; and if the current ship is not in the cached ship lock, defining the state information of the current ship as the ship leaving the ship lock.

[0068] According to the above steps, the ship state information can be calculated based on the ship real-time position information and the ship lock area information according to the ship grouping, the ship and ship lock relationship information is generated by assembling the ship information, the ship lock information, the ship state information, and the ship real-time position information, and the ship and ship lock relationship information is sent to the ship lock data processing center to determine the ship passing data of each ship lock as a grouping information column.

[0069] In step S104, the ship passing data is determined based on the relationship between each ship and the ship lock, taking each ship lock as a grouping information column.

[0070] Optionally, the step S104 comprises: judging whether the current group has cached the lock information according to the group information column of each lock; in the case that the current group has cached the lock information, obtaining the state information of the current ship in the ship-lock relationship; in the case that the state information is that the ship has just entered the lock, determining that the current lock has a ship entering, obtaining the ship navigation information of the current ship and the sub-area of the current ship in the current lock, wherein the ship navigation information comprises at least one of the ship speed, the ship latitude and longitude, the time and the lock sub-area; in the case that the sub-area of the current ship in the current lock is the waiting zone, clearing the historical lock-passing navigation information of the current ship, and caching the information and the entering time of the current ship entering the first waiting zone, wherein the first waiting zone is one of the upstream waiting zone and the downstream waiting zone; caching the lock chamber information and the entering time of the current ship after entering the lock chamber from the waiting zone; caching the information and the entering time of the current ship entering the second waiting zone from the lock chamber; in the case that the current ship is confirmed to pass through the first waiting zone, the lock chamber and the second waiting zone in the lock, confirming that the current ship completes the lock-passing process; in the case that the current ship completes the lock-passing process, generating the ship lock-passing data based on the cached information of the ship passing through each lock sub-area.

[0071] When it is detected that the ship state is just entering the lock but is located in the lock chamber of the current lock, there are usually two possible cases: one is that the program is just started and the ship has been docked in the lock chamber of the lock before the program is started, and the other is that the ship opens the position signal transmitter on the ship after entering the lock chamber, at this time, the lock-passing data of the ship in the current lock is incomplete, and the corresponding navigation information of the ship in the current lock cache needs to be cleared.

[0072] In addition, when the ship passes through the current lock, if the cache information of the current lock does not include all the information of the ship entering the waiting zone, the lock chamber and the other side waiting zone, it means that the ship position signal is not received by the position collection program, resulting in the loss of the position information of the ship in the waiting zone or the lock chamber, which may cause errors in the calculation process of the lock-passing data of the ship, and the corresponding navigation information of the ship in the current lock cache needs to be cleared.

[0073] Optionally, the step of caching the lock chamber information and the entering time of the current ship after entering the lock chamber from the waiting zone comprises: after confirming that the current ship has entered the first waiting zone, judging whether the current lock has cached the lock chamber information of the current ship entering the lock chamber; if the current lock has not cached the lock chamber information of the current ship entering the lock chamber, judging whether the current ship has entered the lock chamber of the current lock; if the current ship has entered the lock chamber of the current lock, caching the lock chamber information and the entering time of the current ship entering the lock chamber.

[0074] Optionally, the step of caching the information of the current ship entering the second waiting zone by the lock chamber and the entering time comprises: after confirming that the current ship has cached the information of the first waiting zone and the information of the lock chamber, judging whether the current ship lock has cached the information of the current ship entering the second waiting zone; if the current ship lock has not cached the information of the current ship entering the second waiting zone, judging whether the current ship has entered the second waiting zone by the lock chamber; if the current ship has entered the second waiting zone by the lock chamber, caching the information of the current ship entering the second waiting zone by the lock chamber and the entering time.

[0075] The first waiting zone can be an uplink waiting zone, and the second waiting zone is a downlink waiting zone at this time. If the first waiting zone is a downlink waiting zone, the second waiting zone is an uplink waiting zone at this time. No ship is stopped in the second waiting zone, and stopping occurs in the waiting zone (part of the ship waiting zone will not stop, and the lock gate is directly opened to enter the lock chamber) and the lock chamber (all ships are stopped and wait for water level adjustment). After the completion of the current lock, the complete navigation data of all ships can be obtained to calculate and sort the lock data of the current ship.

[0076] It should be noted that there are two methods for judging whether the current lock is completed: regular judgment and special judgment.

[0077] The regular judgment method is to integrate the navigation data of all ships cached by the current ship lock in the current lock, and to count the number of times of entering the waiting zone, the number of times of entering the lock chamber and the number of times of entering the waiting zone on the other side. If the numbers are consistent, it is considered that the current lock is completed, and data integration and calculation can be performed, otherwise, special judgment is entered.

[0078] There are two methods for special judgment. If the number of ships entering the lock chamber cached by the current ship lock in the current lock is M, and the number of ships entering the waiting zone on the other side is N, then the first method is used for special judgment: if M≥1 and M=N, it is considered that the current lock is completed. If the first method still judges that the current lock is not completed, the second method is entered: if N≥1, M≥3, the relationship between M and N satisfies M-N≥2, and the cumulative stopping time of the last ship leaving the lock chamber from entering the ship lock exceeds the preset time, it is considered that the current lock is completed. If the result of special judgment is that the current lock is completed, data integration and calculation can be performed, otherwise, the next ship and ship lock relationship information is required until the current lock is completed.

[0079] Optionally, after step S104, further comprising: traversing the ship lock data to obtain the passing information of all ships entering the current ship lock, wherein the passing information comprises: the time and position of the ship entering the first waiting lock area, entering the lock chamber and entering the second waiting lock area, the start and end stopping time of the ship in the first waiting lock area and the lock chamber; based on the passing information, calculating the sailing distance, sailing time and average speed of the ship; calculating the waiting lock time length, entering lock time length, lock chamber stopping time length, exiting lock time length, lock passing time length of the ship to obtain the lock passing information of the ship when passing through the current ship lock; and storing the lock passing information of the ship when passing through the current ship lock to the database.

[0080] It should be noted that the lock passing information of the ship when passing through the current ship lock includes but is not limited to: ship lock name, ship lock ID, ship MMSI, ship Chinese name, ship English name, ship type, ship type code, ship tonnage, waiting lock area stay time, waiting lock area stopping time point, lock chamber stay time, lock chamber stopping time point, another side waiting lock area stay time, another waiting lock area stopping time point, lock passing time (not including waiting lock time), total lock passing time (including waiting lock time), waiting lock time, entering lock time, exiting lock time, sailing distance, cumulative time, average speed, lock passing trajectory information, same trip ship number in the current ship lock, etc.

[0081] Through the above steps of the embodiments, the process data and detailed result data of the ship passing through the ship lock can be accurately calculated by using the real-time position data of the ship and the navigation environment information in the ship lock area through the method of stream computing; by using the distributed resource management, real-time stream computing, message queue technology and cache technology to cooperate with each other, the method is not limited by the number and position of the ship lock, has high flexibility, has strong expansibility and high concurrent data processing capacity on the basis of high operation efficiency.

[0082] The embodiment of the application can directly configure the ship lock area through the software interface, and the real-time position information is transmitted by the position information transmitter on the ship, so that the hardware procurement and maintenance costs are saved without installing ship detection equipment on site.

[0083] The application will be described in detail below with reference to another specific embodiment.

[0084] Figure 2 is a flow chart of another optional ship lock passing data determination method based on real-time ship position according to the embodiment of the application, as shown in Figure 2 The method comprises the following steps:

[0085] Step S201, collecting ship position data.

[0086] Step S202, calculating the ship and ship lock relationship information according to the ship grouping.

[0087] Step S203, calculate lock information according to lock grouping.

[0088] Step S204, batch the lock information into the database.

[0089] Step S205, count the lock information of the ship in the database.

[0090] In the embodiment of the application, the big data real-time stream processing technology Flink is used for program calculation, the Kafka message queue is used to transfer data between steps, and is used as a pipeline for data transmission in the calculation process, and Redis is used as a cache.

[0091] The embodiment of the application will be described in detail below in combination with the above steps.

[0092] Step S201, collect ship position data.

[0093] The step S201 specifically includes: collecting real-time position data of the ship, adding a time identifier and encapsulating, sending the encapsulated data to the message queue A; listening to the message queue A, preprocessing the real-time position information of the ship in the received encapsulated data; converting the real-time position information of the ship into a unified format and sending it to the message queue B.

[0094] It should be noted that the preprocessing of the encapsulated data mainly includes: data verification, data cleaning, deduplication, parsing, etc. In the step of converting the original data into a unified format, the unified format includes but is not limited to: ship unique identifier, ship name, ship type, ship longitude, ship latitude, data source (e.g. AIS, Beidou, radar, fusion signal), time point, etc.

[0095] It should be noted that, in order to avoid data loss, the real-time position data of the ship should be collected as quickly and comprehensively as possible when collecting the data for the first time.

[0096] Step S202, calculate the ship-lock relationship information according to the ship grouping.

[0097] The step S202 specifically includes: obtaining lock area data; listening to the message queue B to obtain the real-time position information of the ship in a unified format; based on the lock area data, the real-time position information of the ship is calculated according to the ship grouping to obtain the ship-lock relationship information.

[0098] It should be noted that the ship-lock relationship information at least includes: real-time position data of the ship, ship information, lock information, and ship state information, wherein the ship state information includes: just entering the lock, being in the lock, just leaving the lock, and the ship not entering the lock will be ignored.

[0099] Figure 3is a flow chart of an optional method for calculating the relationship between a ship and a ship lock according to an embodiment of the present application, as shown in Figure 3 The flow steps include:

[0100] 1. Receive a position signal;

[0101] After receiving the real-time position information of the ship from the message queue B, the encapsulated data is checked and parsed, the ship lock area information is obtained, and the conversion to a unified format is parsed;

[0102] 2. Determine whether to cache ship information;

[0103] If the result of the determination is yes, go to step 4 to determine the ship lock information, otherwise go to step 3 to cache;

[0104] 3. Cache ship information;

[0105] 4. Determine whether to cache ship lock information;

[0106] If the result of the determination is yes, go to step 9, otherwise go to step 5 to obtain the ship lock information;

[0107] 5. Obtain the ship lock information;

[0108] 6. Determine whether the current ship is located in any ship lock;

[0109] If the result of the determination is yes, go to step 7, otherwise return to step 1 to wait for the next ship position signal;

[0110] 7. Set state information 1: if it is detected that the current ship is located in a ship lock in the ship lock area, set the state information of the ship to "the ship has just entered the ship lock", and go to step 8;

[0111] 8. Cache the ship lock information;

[0112] Write the ship lock information of the current ship into the cache, and go to step 13;

[0113] 9. Determine whether the ship is in the ship lock;

[0114] If the ship lock information has been cached in the current ship packet, it means that the ship may still be in the ship lock, according to the ship position and the ship lock range, calculate whether the ship is still in the ship lock, if the result of the determination is yes, go to step 10, otherwise go to step 11;

[0115] 10. Set state information 2: if it is detected that the ship is still docked in the ship lock, set the state information of the ship to "the ship has been in the ship lock", and go to step 13;

[0116] 11. Set state information 3: if it is detected that the ship is not currently in the ship lock, set the state information of the ship as "the ship has just left the ship lock", and enter step 12 to clean the cache;

[0117] 12. Clean the cache;

[0118] When the ship leaves the ship lock, delete the cached ship lock information, and enter step 13;

[0119] 13. Generate relationship information;

[0120] Assemble the ship information, the ship lock information, the state information of the ship, and the real-time position information of the ship to generate the relationship information between the ship and the ship lock;

[0121] According to the above process, the relationship between the ship and the ship lock can be calculated based on the real-time position information of the ship and the ship lock area information according to the ship grouping, and the relationship information between the ship and the ship lock is sent to the next program to continue to calculate the ship lock data according to the ship grouping.

[0122] Step S203: Calculate the ship lock data according to the ship grouping.

[0123] The step S203 specifically includes: calculating the relationship information between the ship and the ship lock according to the ship grouping to obtain the ship lock data of the ship in the ship lock; and generating an SQL statement based on the ship lock data and sending the SQL statement to the message queue C.

[0124] Figure 4 is a schematic diagram of an optional ship lock area data layout according to an embodiment of the application, as shown in Figure 4 The ship lock can be divided into the following areas: an upstream waiting area, a downstream waiting area, and a lock chamber. It should be noted that the area data of the ship lock is composed of a set of N groups of latitude and longitude points, N is an integer greater than 3, and the latitude and longitude points in each set are sequentially connected, and the first and last points are connected to form a non-intersecting polygon with a certain area (shown by the dashed area in Figure 4 ).

[0125] Figure 5 is a flowchart of an optional method for calculating the ship lock data of the ship in the ship lock according to an embodiment of the application, as shown in Figure 5 The flowchart includes the following steps:

[0126] 1. Receive relationship information;

[0127] Wait for the relationship information between the ship and the ship lock, and the data content mainly includes: real-time position information of the ship, ship lock information, ship information, and state information of the ship;

[0128] 2. Determine whether the ship lock information is cached;

[0129] The received current ship lock information is compared with the ship lock information in the group to determine whether the current ship lock information has been cached in the group. If the result is yes, go to step 4, otherwise go to step 3 for caching;

[0130] 3. Cache ship lock information;

[0131] Cache the current ship lock information into the group;

[0132] 4. Get status information;

[0133] According to the current ship lock information, the ship state information in the ship and ship lock relationship information is extracted. The ship state information is that the ship has just entered the ship lock, or the ship has been in the ship lock, or the ship has just left the ship lock;

[0134] 5. Determine: status information;

[0135] According to different ship state information, different operations are taken: if the ship state is that the ship has just entered the ship lock, it indicates that the current ship lock has a ship entering, go to step 6 to determine whether to enter the waiting area or the chamber; if the ship state is that the ship has been in the ship lock, it indicates that the ship in the current ship lock has been in the current ship lock, go to step 11 to determine the ship passage information; if the ship state is that the ship has left the ship lock, it indicates that the ship in the current ship lock has left the waiting area, go to step 18 to determine the ship lock cache;

[0136] 6. Determine: whether to enter the waiting area or the chamber;

[0137] Because there is a gap between the ship lock area and the internal sub-area, the line cannot be completely close, and the ship position signal may just exist in the ship lock, but not in any sub-area. Moreover, the data not in the sub-area needs to be recorded, and it needs to be noted that when the ship just enters the ship lock, the first entered sub-area is the waiting area, and if it directly enters the chamber without passing through the waiting area, it is invalid data.

[0138] When a ship enters the current ship lock, determine whether the ship is in the waiting area (including: uplink waiting area and downlink waiting area) or the chamber of the current ship lock. If the result is yes, go to step 8 for further determination, otherwise go to step 7;

[0139] 7. Record complete navigation information;

[0140] Record the complete navigation information of the ship in the ship lock, including: ship speed, ship latitude and longitude, time and ship lock sub-area, etc. After saving the record, return to step 1 to wait for data;

[0141] 8. Determine: specific position of the ship;

[0142] If the ship is still in the current ship lock, the specific position of the ship in the current ship lock, i.e. the lock chamber or the waiting area, is determined. It should be noted that, since the entry area and the exit area of the lock chamber of the ship lock both have waiting areas, the "waiting area" here refers to the waiting area entered by the ship before entering the lock chamber (the specific name may be Figure 4 the uplink waiting area shown in FIG. 1B, or the downlink waiting area). The "another side waiting area" refers to the waiting area entered by the ship after leaving the lock chamber (when the "waiting area" is the uplink waiting area shown in FIG. 1B, the "another side waiting area" is the downlink waiting area; when the "waiting area" is the downlink waiting area, the "another side waiting area" is the uplink waiting area). If the specific position of the ship is the waiting area, the process proceeds to step 10 to process the ship information. If the specific position of the ship is the lock chamber, the process proceeds to step 9. Figure 4

[0143] 9. Clear the navigation information.

[0144] When the program detects that the ship is just entering the ship lock but is located in the lock chamber of the current ship lock, there are usually two possible situations. One is that the program is just started and the ship has been parked in the lock chamber of the ship lock before the program is started. The other is that the ship enters the lock chamber and then turns on the position signal transmitter on the ship. At this time, the transit data of the ship in the current ship lock is incomplete, and the corresponding navigation information in the cache of the current ship lock needs to be cleared.

[0145] In addition, when the ship passes through the current ship lock, if the cache information of the current ship lock does not include all the information of the ship entering the waiting area, the lock chamber and the other side waiting area, it means that the position signal of the ship is not received by the position collection program, resulting in the loss of the position information of the ship in the waiting area or the lock chamber, which may cause errors in the calculation process of the transit data of the ship. The corresponding navigation information in the cache of the current ship lock needs to be cleared.

[0146] 10. Process the ship information 1.

[0147] If it is detected that the state information of a ship is just entering the ship lock and the specific position is the waiting area of the current ship lock, the historical cache transit navigation information of the ship is cleared, and the cache waiting area information of the ship is processed, including the waiting area information of the current ship and the specific time point of entry. At the same time, the current ship also caches the relevant information that the ship has entered the waiting area, and then proceeds to step 7.

[0148] 11. Determine the waiting area information.

[0149] If the state of the ship is that the ship has been in the ship lock, it indicates that the ship is still passing through the ship lock. It is determined whether the ship has cached the waiting area information. If the result of the determination is yes, the process proceeds to step 12 to determine the lock chamber information. Otherwise, the process proceeds to step 6 for determination. ​

[0150] 12. Determine: lock chamber information;

[0151] Continue to determine whether the ship also caches the lock chamber information of the current ship lock, if the result is yes, go to step 15, otherwise go to step 13;

[0152] 13. Determine: whether to enter the lock chamber;

[0153] If the ship does not cache the lock chamber information of the current ship lock, and the current ship lock also does not cache the relevant information of the ship entering the lock chamber, determine whether the ship has entered the lock chamber of the current ship lock, if the result is yes, go to step 14 to process the ship information, otherwise go to step 7;

[0154] 14. Process ship information 2;

[0155] If the ship enters the lock chamber of the current ship lock, cache the lock chamber information of the ship, including the lock chamber information of the current ship and the specific time point of entering, at the same time, the current ship lock also records the time information of the first ship entering the lock chamber, and then go to step 7;

[0156] 15. Determine: another waiting area information;

[0157] Continue to determine whether the ship also caches the other side waiting area information of the current ship lock, if the result is yes, go to step 7, otherwise go to step 16;

[0158] 16. Determine: whether to enter another waiting area;

[0159] If the result is yes, go to step 17 to process the ship information, otherwise go to step 7;

[0160] 17. Process ship information 3;

[0161] If the ship enters the other side waiting area of the current ship lock, cache the other side waiting area information of the ship, including the other side waiting area information of the current ship and the specific time point of entering, at the same time, the current ship lock also records the time information of the first ship entering the other side waiting area, and then go to step 7;

[0162] 18. Determine: ship lock cache information;

[0163] If the ship state is that the ship leaves the ship lock, indicating that there is a ship leaving the waiting area in the current ship lock, determine whether the cache information of the current ship lock includes all the information of the ship entering the waiting area, the lock chamber and the other side waiting area, if the result is yes, go to step 19, otherwise go to step 9 for data cleaning;

[0164] 19. Determine: whether the current lock is over;

[0165] The end of the current lockage is judged regularly. The regular judgment method is: integrating the navigation data of all ships cached by the current ship lock in the current lockage, respectively counting the number of times of entering the waiting lock area, entering the lock chamber and entering the waiting lock area on the other side, if the number is consistent, it is considered that the current lockage is over, and the data calculation in step 21 is entered, otherwise the special judgment in step 20 is entered;

[0166] 20. Special judgment;

[0167] There are two methods for special judgment. If the number of ships entering the lock chamber cached by the current ship lock in the current lockage is M, and the number of ships entering the waiting lock area on the other side is N, then the first method is used for special judgment:

[0168] Method 1: If M≥1 and M=N, it is considered that the current lockage is over;

[0169] If the first method still judges that the current lockage is not over, the second method is entered:

[0170] Method 2: If N≥1, M≥3, the relationship between M and N satisfies M-N≥2, and the cumulative docking time of the last ship leaving the lock chamber since entering the ship lock exceeds the preset time, it is considered that the current lockage is over;

[0171] If the result of special judgment is that the current lockage is over, the data calculation in step 21 is entered, otherwise the step 7 is entered;

[0172] 21. Data calculation;

[0173] All ship information entering the waiting lock area cached by the current ship lock is traversed;

[0174] The time and position information of all ships entering the waiting lock area, entering the lock chamber (leaving the waiting lock area) and entering the waiting lock area on the other side (leaving the lock chamber) are calculated one by one;

[0175] The start and end docking times of all ships in the waiting lock area and the lock chamber are obtained one by one;

[0176] The detailed information of all ships passing through the current ship lock is calculated one by one, including: navigation distance, navigation time, average speed, waiting lock time, entering lock time, waiting time in lock chamber, leaving lock time, passing through lock time, up and down type and other information;

[0177] After the calculation is completed, the result data is sent to step 22 for batch preparation;

[0178] 22. Prepare batch data;

[0179] Receive result data, add SQL storage statement based on result data, and send to data batch storage sub-process.

[0180] It should be noted that the result data is the detailed information of each ship passing through the lock, including but not limited to: lock name, lock ID, ship MMSI, ship Chinese name, ship English name, ship type, ship type code, ship tonnage, waiting zone stay time, waiting zone stop time point, chamber stay time, chamber stop time point, other side waiting zone stay time, other waiting zone stop time point, passing time (not including waiting time), total passing time (including waiting time), waiting time, entering time, exiting time, navigation distance, cumulative time, average speed, passing trajectory information, and the number of same-trip ships in the lock.

[0181] Step S204, batch storing the passing information.

[0182] This step specifically includes: listening to the message queue C, splicing and caching the received SQL statements; when the number of cached data is greater than the preset number or the cumulative duration is greater than the preset duration, the spliced SQL statement is executed and the cached data is emptied.

[0183] It should be noted that this step aims to batch store the passing information, and the batch process is completed by executing the batch storage SQL statement. The configuration of the batch number and the trigger execution duration needs to consider many factors, such as the number of ship locks, the number of ships in navigation, the frequency of ship position signal transmission, database connection pool configuration information, the frequency of database table producing storage data, and database batch storage efficiency, and make reasonable evaluation.

[0184] Figure 6 is a flowchart of an optional batch storage flow computing method for passing information according to an embodiment of the present application, as shown in Figure 6 The flowchart of the flow computing method is as follows:

[0185] 1, waiting for receiving batch storage data;

[0186] The batch storage data is the SQL storage statement to be added;

[0187] 2, judge: whether it is the first SQL statement in this period;

[0188] If the result is yes, go to step 3, otherwise skip step 3 and go directly to step 4.

[0189] 3, get the prefix of the added statement and cache;

[0190] The SQL storage statement to be added contains table and added statement information. According to the table information of the SQL statement, the prefix of the added statement of the SQL statement is obtained and cached;

[0191] 4, splice SQL statement;

[0192] Splice the received SQL statement to be added with the SQL statement in the cache, and cache again;

[0193] 5, judge: whether the number of received statements reaches the preset value;

[0194] Compare the number of accumulated received SQL statements in the current period with the preset value, if the accumulated number is greater than or equal to the preset value, go to step 6 to execute the storage, otherwise skip step 6 and go to step 7 to judge the duration;

[0195] 6, execute the SQL storage statement in the cache;

[0196] The executable SQL storage statement in the cache is spliced after execution, and the cache is cleared after the storage is completed;

[0197] 7, judge: whether the duration reaches the preset duration;

[0198] Compare the accumulated time length from the addition of the first SQL storage statement to the current time point in the current period with the preset duration, if the accumulated duration is greater than or equal to the preset duration, go to step 6 to execute the storage, otherwise return to step 1 to wait for the next SQL storage statement to be added;

[0199] 8, clear the cache;

[0200] After completing the storage, the temporary data generated in the statement execution process is cleared, and the current period is ended;

[0201] 9, judge: whether the program is stopped;

[0202] If the result of the judgment is yes, go to step 10 to end the current batch storage, otherwise return to step 1 to wait for the next SQL storage statement to be added and perform the next period;

[0203] 10, end.

[0204] Step S205, count the lock information of the ship in the database.

[0205] In the embodiment of the application, the real-time position data of the ship and the navigation environment information in the ship lock area are used to accurately calculate the process data and detailed result data of the ship passing through the lock by a streaming calculation method; distributed resource management, real-time streaming calculation, message queue technology and cache technology are used to cooperate with each other, on the basis of achieving high efficiency, strong expansibility and high concurrent data processing capacity.

[0206] The ship lock region can be directly configured through a software interface, and the number and position of the ship locks are not limited, and the flexibility is high; meanwhile, the ship monitoring device does not need to be installed on site, and the hardware procurement and maintenance costs are saved.

[0207] The application will be described below in combination with another alternative embodiment.

[0208] Embodiment two

[0209] The ship lock data determination device based on the real-time position of the ship provided in this embodiment comprises a plurality of implementation units, each of which corresponds to each implementation step in the above embodiment one.

[0210] Figure 7 is a schematic diagram of an alternative ship lock data determination device based on the real-time position of the ship according to the embodiment of the application, as Figure 7 shown, the determination device can comprise: an acquisition unit 71, an acquisition unit 72, a first determination unit 73, a second determination unit 74, wherein,

[0211] The acquisition unit 71 is configured to acquire the real-time position data of each ship, and encapsulate the real-time position data according to a preset data format to obtain ship position data corresponding to each ship.

[0212] The acquisition unit 72 is configured to acquire the area information of each ship lock to obtain ship lock area data.
