Description

Technical Field

[0001] This invention belongs to the field of ship pollutant monitoring technology, specifically relating to a remote monitoring method and system for ship bilge oily wastewater based on consortium blockchain. Background Technology

[0002] Shipping is a vital pillar of regional economic development, but it also brings numerous environmental problems, one of which is the discharge of ship wastewater. Statistics show that, including the Yangtze and Pearl River systems, there are an estimated 120,000 ships on my country's inland waterways, generating a staggering amount of wastewater annually. This wastewater contains various oily organic pollutants, heavy metals, and other pollutants, posing a significant threat to the ecological environment. With increasing public awareness of environmental protection, my country has imposed stricter requirements on the regulation of ship oily wastewater and has enacted relevant regulations to rigorously control the discharge of oily wastewater from ships.

[0003] Oily bilge water refers to water contaminated by oil generated from machinery. It is one of the main sources of oily wastewater from ships and is produced by all types of vessels. Currently, there are two treatment methods for oily bilge water: one is to collect the oily wastewater and discharge it into a dedicated receiving facility; the other is to treat the oily wastewater through an oil-water separator before discharging it in compliance with standards. Currently, it is common for some ships to illegally discharge oily bilge water into the water in order to save operating costs, and they evade supervision by forging oil record books or wastewater receiving certificates, which brings significant difficulties to regulatory departments. Problems exist such as inaccurate calculation of wastewater generation, inaccurate measurement of discharge, and ineffective supervision. Due to the difficulty in obtaining relevant sensor data, the current methods for supervising oily bilge water are relatively limited and heavily reliant on manpower. Regulatory departments mainly rely on surface patrols, random boarding inspections, and eyewitness reports for ship oily wastewater supervision. This requires on-site inspection of relevant documents and equipment, and the level of informatization is low. With hundreds of thousands of ships in my country, supervision is difficult, and illegal discharges occur frequently, causing significant harm to the aquatic environment.

[0004] Currently, there are also a few solutions that use sensors for remote monitoring. For example, the invention patent with publication number CN106647498A discloses a multi-functional ship integrated management system, which uses the ship's AIS system and various sensors to remotely monitor the management of the ship's own sewage. However, its monitoring results are affected by the sensor status, and the data reliability decreases and is easily tampered with after long-term operation. Summary of the Invention

[0005] In view of this, the present invention proposes a remote monitoring system and method for ship bilge oily wastewater based on consortium blockchain, which is used to solve the problem of low reliability of ship bilge oily wastewater monitoring.

[0062] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0063] Consortium blockchains are semi-public blockchains used by a group or organization alliance. They can establish a mutual trust mechanism for multi-party collaboration and, based on smart contracts, build consensus-based regulatory protocols. Data on the blockchain is difficult to falsify, enabling multi-party governance, full traceability, and intelligent operation. Experiments show that the above characteristics of consortium blockchains are suitable for remote monitoring of ship oil and wastewater, and are of significant importance for real-time monitoring of ship bilge water, extraction of evidence of illegal wastewater discharge, and accountability of shipping companies.

[0064] Furthermore, the inherent advantages of consortium blockchains can improve regulatory efficiency and credibility. Therefore, it is entirely feasible to establish a remote monitoring system for ship bilge oil and wastewater based on consortium blockchains, and it can generate good social and economic benefits.

[0065] Please see Figure 1 This invention proposes a method for remote monitoring of oily wastewater in ship bilges based on consortium blockchain, the method comprising:

[0066] S1. Upload data related to the remote monitoring of oily wastewater in ship bilges to the data storage server.

[0067] Specifically, the data related to the remote monitoring of oily wastewater in ship bilges includes: AIS data, ship static data, oily wastewater discharge control zone data, oily wastewater receiving unit data, and oily wastewater monitoring sensor data.

[0068] Among them, ship AIS data is used to record ship trajectory data, including position, speed and heading.

[0069] Ship static data is used to record information such as ship name, MMSI, ship type, tonnage, oil filtration equipment parameters, and oily wastewater storage system capacity.

[0070] Oily wastewater discharge control zone data is used to record data such as the type of discharge control zone, discharge control standards and requirements, and regional coordinate range.

[0071] Data on bilge oily wastewater receiving units is used to record information such as unit name, oily wastewater receiving qualifications, and oily wastewater receiving equipment.

[0072] With the relevant sensors installed, the sensor data records data such as the liquid level in the oily wastewater tank and the flow rate of the oily wastewater being delivered.

[0073] S2. Based on data related to remote monitoring of ship bilge oily wastewater, establish a blockchain alliance for monitoring ship bilge oily wastewater among different regulatory departments, shipping companies, and wastewater receiving units.

[0074] This invention establishes the Fbric consortium blockchain, which grants each organization specific permissions by issuing specific certificates, such as joining a consortium blockchain channel and writing or modifying data on ships, oil and wastewater, and receiving units in the blockchain ledger.

[0075] Then, a monitoring channel for ship bilge oily wastewater is established between organizations with specific certificates, enabling private communication between these organizations within the blockchain. Based on consortium blockchain consensus services, it provides on-chain management functions for ship bilge oily wastewater data; the Fbric consortium blockchain also provides data encryption and distributed storage management functions.

[0076] S3. Ships can upload their bilge oil and wastewater data to the consortium blockchain by initiating proposals, and remotely monitor the bilge oil and wastewater based on blockchain smart contracts.

[0077] The ship bilge oily wastewater data of the present invention includes relevant data on the storage, treatment and delivery of ship bilge oily wastewater.

[0078] This invention adopts different regulatory methods based on whether the ship uses an oil-water separator: if the ship uses an oil-water separator, the usage of the oil-water separator is checked and the ship's oil-water separator is regulated; if an oil-water separator is used, it indicates that the ship's oily wastewater is received on shore, and the ship's oily wastewater reception is regulated by checking the data on the reception and treatment of oily wastewater in the bilge.

[0079] Step S3 specifically includes the following steps:

[0080] S31. Monitoring of ship oil-water separators: Based on consortium blockchain smart contracts, it is used to identify whether ships accurately record the usage of oil-water separators.

[0081] If a vessel uses an oil-water separator, the vessel's oil-water separator will be subject to oversight. Based on a pre-defined consortium blockchain smart contract, the authenticity of the vessel's oil and wastewater treatment records, the compliance of the oil-water separator's usage area, the reasonableness of residual oil quantity records, and the reasonableness of the amount of oil and wastewater treated will be checked.

[0082] Figure 2 This is a schematic diagram of the process for monitoring the ship oil-water separator according to the present invention, as shown below. Figure 2 As shown, step S31 further includes the following sub-steps:

[0083] S311. Verify the authenticity of oily wastewater treatment operations in ship records based on a pre-defined consortium blockchain smart contract.

[0084] The method for determining the authenticity of oily wastewater treatment operations is to calculate whether the amount of oily wastewater treated uploaded by the ship exceeds the maximum rated treatment capacity of the oil-water separator and whether it exceeds the volume of the wastewater tank.

[0085] The smart contract for verifying the authenticity of oily wastewater treatment operations is as follows:

[0086]

[0087] in, f epq The result of determining the authenticity of the oily wastewater treatment operation; Q m For the number of oily wastewater treatments uploaded by the ship in a single operation, m 3 ; T The time for a single oily wastewater treatment session is in hours (h). C The rated oil and wastewater treatment capacity of the oil-water separator is m 3 / h; Q s The maximum oily wastewater storage capacity on board is m 3 & represents logical AND.

[0088] S312. Check the compliance of the oil-water separator's usage area based on a pre-set consortium blockchain smart contract.

[0089] The method for determining the compliance of the oil-water separator's usage area is as follows: the vessel must be underway and discharge water treated by the oil-water separator in a non-emission control area. The use area of ​​the oil-water separator and the navigation status are judged based on AIS data to determine whether they comply with relevant regulations.

[0090] The smart contract for checking the compliance of the oil-water separator's usage area is as follows:

[0091]

[0092] in, f a,i fori The results of the compliance assessment of the oil-water separator's usage area and navigation status at any given time; Speed i For ships in i The speed of time, knot; V b The speed threshold for the ship's navigation state. V b Three knots are acceptable; Coordinate i For ships in i The coordinates of time; B This area is designated as a zero-discharge zone for oily wastewater.

[0093] S313. Check the reasonableness of residual oil quantity records based on pre-set consortium blockchain smart contracts.

[0094] The reasonableness of the residual oil quantity record is determined as follows: After the bilge oily wastewater is treated by the oil-water separator, the water that meets the discharge standards is discharged into the river or sea. The remaining oil separated on the ship is related to the oil content of the bilge oily wastewater. The residual oil quantity cannot exceed the upper and lower limits of the oil content of the oily wastewater.

[0095] The smart contract for checking the reasonableness of the residual oil quantity record is as follows:

[0096]

[0097] in, f r The result of the reasonableness determination of the residual oil quantity; Q r For the amount of residual oil uploaded by the ship, m 3 ; Q m For the number of oily wastewater treatments uploaded by the ship in a single operation, m 3 ; α , β The oil content coefficients for the bilge oily wastewater are taken as 0.2% and 2%, respectively.

[0098] S314. Check the reasonableness of the number of oily wastewater treatments based on a pre-set consortium blockchain smart contract.

[0099] The reasonableness of the amount of oily wastewater treated is determined by judging whether the amount of oily wastewater treated by the ship within a certain period of time is lower than the lower limit of the amount of oily wastewater generated in the bilge or higher than the upper limit of the amount of oily wastewater generated.

[0100] The smart contract for checking the reasonableness of the amount of oily wastewater treated is as follows:

[0101]

[0102] in,f p The result of determining the rationality of the amount of oily wastewater treated within a certain period of time; The first upload for the ship i Number of secondary oily wastewater treatments, m 3 ; The minimum amount of bilge oily wastewater generated by a ship per unit time, m 3 / d; T a , T b These are the lower and upper limits of the inspection time window, respectively; The maximum amount of bilge oily wastewater generated by a ship per unit time, m 3 / d.

[0103] Among them, the maximum amount of bilge oily wastewater generated by the ship per unit time and minimum value The value is determined based on the ship's deadweight tonnage, and the reference values ​​are shown in Table 1. In practical applications, this value can be appropriately reduced according to the ship's construction year and maintenance level.

[0104] Table 1. Reference values ​​for the amount of bilge oily wastewater generated by ships per unit time.

[0105]

[0106] S32. Supervision of the receipt of oily wastewater from ship bilges: Based on the consortium blockchain smart contract, the receipt of oily wastewater from ships is supervised to prevent the falsification of oily wastewater receipt data.

[0107] If a vessel uses shore-based oily wastewater reception, the following procedures will be implemented to regulate this process: The vessel initiates an oily wastewater delivery application, detailing the quantity, location, and time of delivery. A qualified wastewater receiving unit responds, and after the reception is completed and a receipt is issued, a pre-defined consortium blockchain smart contract will be used to verify the authenticity of the receipt, the reasonableness of the delivery time interval, and the reasonableness of the quantity delivered. Qualified wastewater receiving units are those with the necessary qualifications for receiving bilge oily wastewater, capable of providing services at the designated location (dock or receiving / disposal vessel), possessing sufficient capacity for oily wastewater reception equipment, and having available reception time windows.

[0108] Figure 3 This is a flowchart illustrating the ship oily wastewater reception and monitoring method of the present invention, as shown below. Figure 3 As shown, step S32 further includes the following sub-steps:

[0109] S321. Verify the authenticity of the ship's oily wastewater receipt certificate based on a pre-set consortium blockchain smart contract.

[0110] The method for verifying the authenticity of ship oily wastewater receipt certificates is as follows: by checking whether the distance between the wastewater delivery vessel and the wastewater receiving equipment exceeds a threshold and the error in the quantity of oily wastewater delivered, it can be determined whether the receipt certificate is suspected of being forged.

[0111] The smart contract for verifying the authenticity of ship oily wastewater receipt certificates is as follows:

[0112]

[0113] in, f c The results of the verification of the authenticity of the oily wastewater reception certificate; d The distance between the sewage delivery vessel and the sewage receiving point is expressed in meters (m). R The distance threshold is m; Q l For the sewage flow rate uploaded by the flow meter, m 3 ; δ As the error threshold, it can be taken as... δ= 0.05.

[0114] S322. Check the reasonableness of the oily wastewater delivery time interval based on the pre-set consortium blockchain smart contract.

[0115] The reasonableness of the time interval for oily wastewater delivery is determined by judging whether the time interval between two adjacent oily wastewater delivery operations exceeds the prescribed threshold.

[0116] The smart contract for checking the reasonableness of the oily wastewater delivery time interval is:

[0117]

[0118] in, f at The result of the reasonableness assessment of the time interval for receiving oily wastewater; T i For the first i Oily wastewater reception time T i-1 For the first i- Time for receiving oily wastewater once Q s The maximum oily wastewater storage capacity on board is m 3 ; Q i-1 s for T i-1 Oily wastewater storage volume at time, m 3 ; q e min The minimum amount of oily wastewater generated by a ship per unit time, m 3 / d.

[0119] S323. Check the reasonableness of the quantity of oily wastewater delivered based on a pre-set consortium blockchain smart contract.

[0120] The reasonableness of the quantity of oily wastewater delivered is determined by whether the quantity of oily wastewater delivered this time is greater than the minimum quantity of oily wastewater generated within the oily wastewater reception interval and less than the maximum oily wastewater storage capacity on board.

[0121] The smart contract for checking the reasonableness of the quantity of oily wastewater delivered is as follows:

[0122]

[0123] in, f a The result of determining the reasonableness of the quantity of oily wastewater received; For the first i Quantity of oily wastewater received, m 3 ; The minimum amount of oily wastewater generated by a ship per unit time, m 3 / d; T i For the first i Oily wastewater reception time T i-1 For the first i- Time for receiving oily wastewater once; Q s The maximum oily wastewater storage capacity on board is m 3 .

[0124] This invention utilizes blockchain smart contracts to determine the validity and authenticity of ship oily wastewater data. After the blockchain smart contract verifies that the bilge oily wastewater monitoring data is correct, the data is uploaded to the blockchain and stored in the consortium blockchain ledger to prevent the data from being forged or tampered with.

[0125] Furthermore, when data is uploaded to the blockchain, the consortium blockchain sorting node is used to sort the bilge oil sludge data based on the consortium blockchain consensus service, avoiding issues of disordered order and duplication during data upload, thus improving the quality of blockchain data. After the data is uploaded to the blockchain, it undergoes consortium blockchain data encryption and distributed storage, including blockchain file storage and LevelDB storage. The file storage is used to store block segment files, while the LevelDB storage is used to store index information and WorldState.

[0126] S4. Reporting of illegal discharge of oily wastewater: Encourage public supervision and reporting of ships that illegally discharge oily wastewater from their bilges. Establish a blockchain virtual currency incentive mechanism to enhance public enthusiasm for supervision.

[0127] Figure 4This is a schematic diagram of the reporting process for illegal discharge of oily wastewater according to the present invention, such as... Figure 4 As shown, if a member of the public reports illegal discharge of oily wastewater through the consortium blockchain, the regulatory department will verify the report. If the report is found to be true, the report will be written into the consortium blockchain and the whistleblower will be rewarded with virtual currency.

[0128] The technical solution of the present invention will be illustrated below with specific data.

[0129] Let ship A be equipped with an oil-water separator and ship B be without an oil-water separator. The static data of the ships are shown in Table 2.

[0130] Table 2 Static Data of Ships

[0131]

[0132] Based on a smart contract on the consortium blockchain, an inspection of the oil-water separator usage was conducted on vessel A. A record of an oily wastewater treatment session uploaded by vessel A to the consortium blockchain shows: 5.71 m³ of oily wastewater was treated. 3 The processing time was from 7:05 AM to 7:25 PM on March 11, 2022, and the amount of residual oil separated was 0.06 m³. 3 It has been 5 days since the last oily wastewater treatment.

[0133] (1) The blockchain smart contract checks the authenticity of the oily wastewater treatment operation recorded by vessel A:

[0134] The results of the authenticity check of the oily wastewater treatment operation met the requirements.

[0135] (2) Blockchain smart contract check for compliance of the oil-water separator usage area of ​​vessel A: Vessel A had a speed greater than 3 knots during the period from 11:05 on March 11, 2022 to 15:25 on March 11, 2022. The waters in which it was located were not emission control areas, and the oil-water separator usage area was compliant.

[0136] (3) The blockchain smart contract checks the reasonableness of the residual oil quantity record of vessel A:

[0137] This indicates that the results of the inspection on the reasonableness of the residual oil quantity record meet the requirements.

[0138] (4) Blockchain smart contract checks the reasonableness of the amount of oily wastewater treated by ship A:

[0139] This indicates that the results of the inspection on the reasonableness of the amount of oily wastewater treated meet the requirements.

[0140] The oily wastewater reception and monitoring of vessel B is carried out based on the consortium blockchain smart contract. Vessel B is about to deliver oily wastewater at port X, 3 days after its last delivery.

[0141] (1) Vessel B initiated an application for delivery of bilge oily wastewater, planning to deliver 7.32 m³ of bilge oily wastewater at Port X at 12:00 on March 11, 2022. 3 .

[0142] (2) Receiving Company C responded to the delivery application of Vessel B. Receiving Company C is qualified to receive bilge oily wastewater and can provide services at Port X. The remaining capacity of the oily wastewater receiving equipment is 18.6m³. 3 Oily wastewater reception operations can be carried out within the same time period.

[0143] (3) Blockchain smart contract checks the authenticity of the oily wastewater receipt certificate of vessel B:

[0144] This indicates that the verification results for the authenticity of the oily wastewater receipt certificate meet the requirements.

[0145] (4) Blockchain smart contract checks the reasonableness of the delivery time interval for oily wastewater:

[0146] This indicates that the inspection results for the oily wastewater delivery interval meet the requirements.

[0147] (5) Blockchain smart contract checks the reasonableness of the quantity of oily wastewater delivered:

[0148] Therefore, the inspection results of the quantity of oily wastewater delivered meet the requirements.

[0149] In the above case, after smart contract identification, no abnormalities were found in the sewage data of both ships A and B. The data was uploaded to the blockchain and stored in the consortium blockchain ledger, which can prevent the forgery or tampering of data and improve the reliability of remote monitoring data of oily sewage in ship bilges.

[0150] Corresponding to the above method embodiments, the present invention also proposes a remote monitoring system for ship bilge oily wastewater based on consortium blockchain, the system comprising:

[0151] Data storage layer: Used to store data related to remote monitoring of oily wastewater in ship bilges, including static data, AIS data, oily wastewater discharge control zone data, oily wastewater receiving unit data, and oily wastewater monitoring sensor data.

[0152] Fbric Consortium Blockchain Layer: Used to establish a consortium blockchain for monitoring ship bilge oil and wastewater based on data from the data storage layer, enabling the on-chain storage and management of ship bilge oil and wastewater data.

[0153] The Fbric consortium blockchain layer includes the following functional modules:

[0154] The certificate issuance module is used to issue specific certificates to organizations, granting each organization specific permissions, such as joining a consortium blockchain channel, writing or modifying data such as ships, oil and wastewater, and receiving units in the blockchain ledger.
