Description

Technical Field

[0001] The invention belongs to the field of ship pollution prevention and control supervision, and specifically relates to a method for treating and checking domestic sewage of ships passing through a lock. Background Art

[0002] In order to implement zero discharge and full onshore disposal of water pollutants, the shipping and navigation authorities have invested huge manpower and material resources, but the supervision work is still based on manual verification, situation analysis is mainly based on regular data summary, and key ship perception is mainly based on experience judgment. The supervision process consumes a lot of manpower and material resources and lacks focus and ineffectiveness. In general, the current supervision method has the following defects: 1) There is a lack of efficient and targeted screening methods for key suspected ships. The main supervision method of the competent authorities is still based on manual inspection. Law enforcement personnel need to board the ship to check the integrity of the ship's lead seals when on patrol, check the past delivery records of individual ships in the information system, and conduct in-depth investigations on suspicious ships. Maritime law enforcement forces are limited and precious, and it is impossible to conduct in-depth investigations on each ship. The random inspection model is not targeted enough.

[0003] 2) There is a lack of convenient means for real-time analysis of ship pollutant disposal. The information system has been completed and put into use, but its service objects are the entire Yangtze River main line. The functional focus is the digitization of ship pollutant transfer points. The regional specificity and intelligent function configuration for ships passing through the locks are insufficient. There is a lack of in-depth analysis of the regional pollutant disposal operation situation. Users still need to manually export relevant data for manual analysis, which is not conducive to the supervision unit's perception of the anti-pollution supervision effect feedback in the jurisdiction, and the flexibility of policy adjustments lacks effective support. Summary of the invention

[0004] The purpose of the present invention is to provide a method for checking the disposal of domestic sewage of ships passing through the locks in response to the above-mentioned problems. The method uses data fusion, multi-level warning, and system linkage technology to integrate ship declaration data, security inspection data, navigation data, pollutant delivery data, receiving unit data, etc., and classifies and grades the data for investigation to accurately warn of the delivery status of domestic sewage of suspicious ships; the relevant business systems passing through the locks interact effectively, and the pollutant delivery of ships passing through the locks is supervised in real time, and the anti-pollution supervision effect of the jurisdiction is dynamically perceived; efficient and targeted screening of key suspected ships and real-time tracking and analysis of the disposal situation; effectively improve the perception efficiency of ship domestic sewage disposal, strengthen the scientific and dynamic analysis of regional situations, improve the level of ship domestic sewage surveillance, monitoring and supervision, and reduce the manpower cost of supervision management.

The next time it passes through the lock for security inspection, execute step 7; Step 7: When a ship passes through the lock again, the ship’s registration information in the remote reporting system and the Three Gorges Navigation e-station will be retrieved, and the ship’s pollutant delivery record will be inspected on site; Step 7.1: If the ship has a delivery record within the last limited time range, it will be classified as a ship with no problems in the review, and the delivery results on the Three Gorges Navigation e-station and the anti-pollution status in the security inspection system will be updated, and the warning will be cancelled, and the process ends; Step 7.2: If the ship has no delivery record within the last limited time, the ship will be classified as a ship with review problems and step 8 will be executed; Step 8: For ships with problems in the review, the maritime on-site supervision procedure is initiated and step 9 is executed; Step 9: For “review of problematic vessels” that have completed the maritime on-site supervision procedures and met the passing standards, update the review results and cancel the warning.

[0006] Furthermore, in step 1, the ship passing through the lock information includes the registration information, security inspection information, departure information and water pollution delivery information of the ship passing through the lock.

[0007] Preferably, in step 2, the calculation formula for the limited time period during which the ship should normally deliver pollutants is as follows:

[0008] In the formula, Indicates the number of days required to accommodate domestic sewage. Indicates various types of ships, The practical significance represented is the limited time period for each type of ship; Indicates the volume of the domestic sewage storage tank; It represents the operating condition coefficient, which is mainly determined by the time when the ship plans to discharge domestic sewage to the receiving facilities.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Figure 1 It is a flow chart of a method for checking the treatment of domestic sewage from ships passing through a lock according to an embodiment of the present invention; Figure 2 It is a schematic diagram of the system architecture of the domestic sewage treatment and investigation system for ships passing through a lock according to an embodiment of the present invention. DETAILED DESCRIPTION

[0018] like Figure 1 As shown, step 1: include the ship passing through the lock in the security inspection plan, and retrieve the registration information of the ship in the remote declaration system and the Three Gorges Navigation e-station.

[0019] Step 2: Use a decision-level data fusion algorithm to associate the ship's declaration information, security inspection information, and water pollution delivery information through corresponding relationships, update the ship's pollution prevention status and warning level, and determine the domestic sewage delivery record of the ship to be inspected within the specified time range before the inspection.

[0020] Step 2.1: If the ship to be inspected has a delivery record, the ship will be classified as a delivered ship and the process ends; Step 2.2: If there is no delivery record for the ship to be inspected, the ship will be classified as an undelivered ship and step 3 will be executed.

[0021] Step 3: Send a reminder of non-delivery of domestic sewage to the undelivered ships through the remote reporting system and the Three Gorges Navigation e-station, update the ship's pollution prevention status to timeout and non-delivery, issue an initial warning, and execute step 4.

[0022] Step 4: When maritime staff conduct on-site safety inspections on ships passing through the lock, the system automatically verifies the domestic sewage delivery records of ships that have been given the initial warning for overdue delivery.

[0023] Step 4.1: If the ship that has not been delivered within the time limit has a delivery record, update the domestic sewage delivery result of the ship in the Three Gorges Navigation e-station, update the pollution prevention status, cancel the warning, and classify the ship as a delivered ship, and end; Step 4.2: If there is no delivery record for the overdue warning ship, the ship will be classified as a ship of key concern, and the anti-pollution status in the security inspection system will be updated to a ship of key concern, and a second warning will be issued, then step 5 will be executed.

[0024] Step 5: Re-verify the sewage delivery records of key vessels within a specified time frame before departure.

[0025] Step 5.1: If the focused ship has a delivery record, update the ship's domestic sewage delivery results, update the pollution prevention status, cancel the warning, classify the ship as a delivered ship, and end; Step 5.2: If there is no delivery record within the specified time before the ship passes the dam and sets sail, the ship will be classified as a ship to be verified, and the anti-pollution status in the security inspection system will be updated to a ship to be verified and three warnings, then execute step 6.

[0026] Step 6: After the ship passes through the lock, the staff will conduct online verification of the ship to be verified.

[0027] Step 6.1: If the staff verifies online that there is no problem with the vessel to be verified, it will be classified as a delivered vessel, the delivery result on the Three Gorges Navigation e-station and the anti-pollution status in the security inspection system will be updated, and the warning will be cancelled; Step 6.2: If the staff verifies online that there may be problems with the ship to be verified, it will be classified as a ship to be inspected next time it passes through the lock, and the anti-pollution status in the security inspection system will be updated and an early warning will be issued. When it passes through the lock for security inspection next time, step 7 will be executed.

[0028] Step 7: When a ship passes through the lock again, its registration information in the remote reporting system and the Three Gorges Navigation e-station will be retrieved, and the pollutant delivery record of the ship will be inspected on site.

[0029] Step 7.1: If the ship has a delivery record within the last limited time range, it will be classified as a ship with no problems in the review, and the delivery results on the Three Gorges Navigation e-station and the anti-pollution status in the security inspection system will be updated, and the warning will be cancelled, and the process ends; Step 7.2: If the vessel has no delivery record within the last specified time, the vessel will be classified as a ship with review problems and step 8 will be executed.

[0030] Step 8: If the maritime on-site supervision procedure is initiated for ships with problems during the review, proceed to Step 9.

[0031] Step 9: For “review of problematic vessels” that have completed the maritime on-site supervision procedures and met the passing standards, update the review results and cancel the warning.

[0032] In step 2, the ship passing through the lock information includes the ship's registration information, security inspection information, departure information and water pollution delivery information.

[0033] In step 2, the formula for calculating the limited time period during which the ship should normally deliver pollutants is as follows:

[0034] In the formula, Indicates the number of days required to accommodate domestic sewage. Indicates various types of ships, The practical significance represented is the limited time period for each type of ship; Indicates the volume of the domestic sewage storage tank; It represents the operating condition coefficient, which is mainly determined by the time when the ship plans to discharge domestic sewage to the receiving facilities. Determine, when t≥24 h, =1; Indicates the persons on board; Indicates the number of people on board, indicating the amount of domestic sewage generated per person per day; Represents typical types of ships.

[0035] In step 2, the decision-level data fusion algorithm associates the ship's declaration information, security inspection information, and water pollution delivery information through corresponding relationships, and updates the ship's pollution prevention status and warning level in a timely manner.

[0036] The decision-level data fusion algorithm is a fusion process performed at the highest level of information representation. Multiple sensors monitor the same target or multiple systems collect various types of data on the same target. Each sensor or system completes preprocessing, feature extraction, recognition or judgment locally to make a preliminary decision on the monitored target. Then each sensor or system transmits the decision information to the fusion center, which makes a final decision through decision-level fusion.

[0037] This technical solution applies a decision-level data fusion algorithm to reorganize and integrate business data such as ship declaration information, security inspection information, departure information, water pollution delivery information, and re-establish the corresponding relationship. The preliminary decisions on monitoring targets provided by different systems are judged through the decision data fusion algorithm, and the ship delivery is reminded, and ships that need further verification are screened out, providing efficient support for maritime personnel to make supervisory decisions.

[0038] For the three warnings in step 3, step 4 or step 5, the ship registration information and the ship declaration information are compared, and the status of the ships passing through the locks is analyzed and summarized. The ships that have not been delivered on time, the ships that are under special attention, the ships that are under special inspection, and the ships with problems that are reviewed are screened and classified into different warning statuses, and different warning statuses are assigned.

[0039] In step 6, drones are used to take photos and videos of ships passing through the locks, supplement pictures and video materials of ships, and increase the characteristic records of ships passing through the locks. The drones can hover at low altitudes and approach operating ships for detailed inspections. By carrying drone cameras, infrared rays, sniffers, loudspeakers and other equipment, they can conduct pollution prevention scans of ships' sewage discharge, exhaust emissions, oil spills, etc. around the clock, collect electronic evidence, fix illegal facts, and notify the ship of any violations found through drone on-site calls to immediately rectify and accept investigation and handling by the maritime department. The overall "water, land and air" integrated pollution prevention and supervision system has been formed, realizing a refined and intelligent governance model from surface to line and then to point, significantly improving the intelligence level, law enforcement efficiency and accuracy of pollution prevention and supervision.

[0040] Three warnings will be issued, the registration information and declared information will be compared, the status of ships passing through the lock will be analyzed and summarized, overdue ships will be screened and classified, ships of key concern will be screened and classified, ships of key inspection will be screened and classified, and different warning status will be assigned.

[0041] The sewage treatment and inspection system for ships passing through the lock includes a data module, an input module, a peripheral interface module, a comparison module and an output module. Figure 2 As shown, including: Data module: used to receive the registration information, early warning information, declaration information and drone photography data of the Three Gorges Navigation e-station, remote declaration system, security inspection system, integrated supervision system and ships passing through the locks, store the above information in the database, and support data retrieval from other modules.

[0042] Peripheral interface module: used to support the data and system input and output functions of mobile phones, maritime law enforcement terminals, law enforcement drones and other law enforcement equipment.

[0043] Comparison module: used to compare the ship's registration information, warning information and declaration information, automatically screen out delivered ships, undelivered ships, ships of key concern, ships to be verified and ships subject to key inspection when passing through the locks, and classify ships in different statuses.

[0044] Output module: used to send the warning information and delivery status information of the classified delivered ships, undelivered ships, key focus ships, ships to be verified and ships passing through the lock for key inspection to the Three Gorges Navigation E-Station and security inspection system.

[0045] Using the embodiment of the present invention, as shown in Tables 1-3, from July 1 to 31, 2024, 1,858 ships passed through the Three Gorges Ship Lock downstream, and 55 ships were not delivered due to system operation push timeout, with a verification push rate of 2.9%. After early warning and delivery reminders, 33 ships delivered domestic sewage in time after the reminder, with a reminder efficiency of 60%, of which 22 ships did not deliver domestic sewage within the specified time range after the reminder. These 22 ships were inspected by drones to collect electronic evidence, and after the next key inspection was carried out when they passed the lock, the verification result was that they were indeed not delivered.

[0046] From the above data and analysis, it can be concluded that the system calculation push rate for ships to be verified is 1.2%, which can screen and remove 98.8% of the targets to be verified. It can be concluded that this big data-based method for the treatment of domestic sewage from ships passing through the lock can greatly reduce the manpower cost of supervision and management, and achieve "targeted" supervision.
