Description

Technical Field

[0001] The present invention relates to the field of ship transportation, and in particular, to a ship berthing method and system. Background Art

[0002] Ship transportation has become an important mode of trade transportation due to its advantages such as large cargo capacity, low cost, and long transportation distance. In the prior art, transportation ships are classified according to types (such as raw material types, equipment types, external cooperation types, construction operation types, etc.) and cargo types (such as steel plates, steel structures, equipment, other dredging, engineering operations, and refueling types, etc.). It is necessary to allocate corresponding docks and berths for ship docking according to ship size, weight, loading and unloading volume, and maximum draft of the voyage, so as to achieve rapid loading and unloading of goods. However, the existing application forms for entering and leaving the port pool and berthing operation approval forms used for ship cargo transportation to dock at the port mainly report the goods information, and the management of ship information, ship types, and cargo types is not in place. It is necessary to report ship-related information through software such as WeChat, resulting in low approval efficiency and inability to meet the actual ship docking requirements. For cargo types and corresponding suppliers, it is relatively mature in actual docking at the port, but most still require the department head to manually maintain the docking port, with a low degree of informatization and slow response in actual ship docking applications.

[0039] Embodiment 1

[0040] This embodiment provides a ship berthing method. As Figure 1 shown, it shows the flowchart of the multi-ship-type berthing method provided in this embodiment; the ship berthing method provided in this embodiment includes the following steps:

[0041] S1: Collect relevant data of ship berthing operations and construct a basic database; construct a ship berthing system based on the basic database, and the ship berthing system integrates application, approval, and scheduling functions.

[0042] S2: The applicant logs in to the ship berthing system and submits a berthing application text.

[0043] S3: The ship berthing system extracts the key information in the berthing application text and automatically generates a ship shore berthing application form.

[0044] S4: Push the ship shore berthing application form to the client of the approver, and the approver approves the ship shore berthing application form and generates an approval result.

[0045] S5: Real-time obtain the information of the visiting ship, input the ship information into the ship berthing system, and the ship berthing system generates a ship scheduling plan.

[0046] S6: Feedback the approval result and the ship scheduling plan to the clients of the applicant and the terminal management personnel.

[0047] Specifically, S1: Collect relevant data of ship berthing operations and construct a basic database; construct a ship berthing system based on the basic database, and the ship berthing system integrates application, approval, and scheduling functions.

[0048] The relevant data of the ship docking business include supplier management data, basic data of ships and cargoes, hierarchical approval system and process, external personnel account and authority data, terminal berth management data, and entry and exit and berthing process records.

[0049] Specifically, supplier management data includes the supplier's basic information (name, contact information, qualification certification, etc.), cooperation history, types of goods that can be provided, etc., which are used to bind the ownership of foreign ships and ensure the compliance of the application and approval process; basic ship data includes basic information such as ship type (such as cargo ship, oil tanker, engineering ship), size (length, width, draft depth), deadweight tonnage, and affiliated company; basic cargo data includes cargo classification (steel, equipment, dangerous goods, etc.), weight, special requirements for loading and unloading (such as moisture-proof and shock-proof), etc.; the hierarchical approval system and process include the list of approval personnel, approval authority, approval level, etc., specifically The approval hierarchy includes multi-level approval, optionally including second-level approval, third-level approval, etc.; approval authority includes cargo review, time adjustment, final confirmation, etc.; outsider accounts and authorities include outsider identity information (name, supplier), account binding records, operational permissions (such as application, inquiry), etc.; terminal berth management data includes terminal distribution map, berth location, berth capacity (maximum ship size / load), current occupancy status (idle / in use), loading and unloading equipment configuration (such as the number of cranes), etc.; port entry and exit and berthing process records include ship entry and exit time, berthing approval records, loading and unloading progress, and historical abnormal events (such as delays, accidents).

[0050] Organizing the above data into a database can clarify the hierarchical approval system, automatically push approval tasks, and clarify the approval responsibilities at all levels; control external users' access rights to the system to ensure data security; support intelligent scheduling algorithms to generate optimal berth allocation plans; achieve full process traceability, and provide data support for optimized scheduling and safety supervision; and provide a basis for allocating berths to ships and scheduling loading and unloading resources.

[0051] Generally, the steps of building a system include: model framework design, model training, and model deployment. Specifically, the steps of building a ship berthing system provided by this embodiment include:

[0052] The S11 design system framework includes an application module, an information extraction module, a docking application form generator, and an approval module. Specifically, the application module provides a user interface for applicants to submit docking application documents. The approval module supports a hierarchical approval process, automatically assigning approval tasks to authorized personnel. It also includes a data interface layer, connecting the underlying database with the functional modules.

[0053] Specifically, the application module can be an interactive page such as a WeChat official account or a Web terminal; the ship berthing application text submitted by the applicant can be a sentence, for example: "A bulk carrier with a length of 150 meters, carrying 20,000 tons of steel, plans to berth at 8 am tomorrow"; it can also be a form that contains specific information about the ship and the cargo.

[0054] S12 Train the information extraction model

[0055] Specifically, the information extraction module extracts keywords from the ship berthing application text submitted by the applicant.

[0056] The steps of training the information extraction model include: S121 Extract entity categories from the pre-training data

[0057] Specifically, the pre-training data is randomly selected historical application texts for training the information extraction module. Specifically, the entity category is to determine the type of information extracted from the berthing application text provided by the applicant. Generally, the entity categories include: ship type, ship size, cargo information, and time, etc. Specifically, ship types include cruise ships, bulk carriers, container ships, etc.; ship sizes include ship length, width, and draft depth, etc.; cargo information includes cargo type, weight, etc.; time includes the planned berthing and departure times.

[0058] S122 Perform sequence labeling on the pre-training data

[0059] Generally, in sequence labeling in the field of natural language processing, the labeling methods include: BIO labeling method, BIOES labeling method, hierarchical labeling method, etc. In this embodiment, the BIO labeling method is adopted. Specifically, the BIO labeling method divides each word into three labels: "B" indicates the start of an entity, "I" indicates the middle or end of an entity, and "O" indicates the non-entity part. For example, if the berthing application text provided by the applicant is: "A bulk carrier with a length of 150 meters, carrying 20,000 tons of steel, plans to berth at 8 am tomorrow", the labeling result is: length → B-ship length; 150 meters → I-ship length; bulk → B-ship type; 20,000 tons → B-cargo weight; steel → B-cargo type; 8 am tomorrow → B-planned berthing time.

[0060] S123 Based on the labeled data, train the pre-training model to generate an information extraction model for entity categories that meet the actual requirements.

[0061] Generally, select models such as the CRF model and the pre-training model for training to obtain the information extraction model. Specifically, in this embodiment, the labeled data is trained based on the conditional random field (CRF) to generate an information extraction model for entity categories that meet the actual requirements.

[0062] Optionally, it further includes validating and optimizing the information extraction model. Taking the historical ship docking application records as the docking application text submitted by users, it is annotated in two ways: manual annotation and annotation by the information extraction module, and the consistency of the annotation is checked to ensure the consistency of the annotation.

[0063] S13 Construct an application form generation module

[0064] Design a template for the ship docking application form. Generally, the ship docking application form includes basic information such as ship type, ship size, ship load, ship - affiliated company, cargo type, cargo weight, and special requirements for cargo.

[0065] Specifically, connect the application form generation module with the information extraction module, and the information extracted by the information extraction module is automatically filled into the application form template to generate the corresponding ship docking application form.

[0066] S14 Construct an approval module

[0067] Specifically, the approval rules and approval processes are integrated in the approval module. The specific data of the approval rules and approval processes can call relevant data in the basic database and can be set according to the actual situation of the ship. Specifically, the approval rules include: cargo compliance rules: for example, dangerous goods require first - level approval; berth allocation rules: the ship size needs to match the capacity of the idle berth; time conflict rules: the same berth cannot be occupied overlappingly.

[0068] Another embodiment further includes: S15 Construct a ship scheduling module for dynamically generating the optimal berth allocation plan for the ship berthing system.

[0069] Specifically, S151: Use the video monitoring module to obtain real - time ship information at the terminal and provide temporary ship data. Specifically, the video module includes devices such as sensors and cameras, which collect real - time information of transportation ships, including the current position of the ship, ship volume, draft of the voyage, etc., and conduct real - time monitoring of the ship to obtain data of all visiting ships at the current terminal;

[0070] S152: Use intelligent algorithms to provide an optimized scheduling plan.

[0071] Generally, the algorithms include ant colony algorithm, particle swarm algorithm, genetic algorithm, etc. In this embodiment, the ant colony algorithm is used to generate an intelligent scheduling plan, considering the actual information of visiting ships, the remaining berths at the current terminal, and the loading and unloading volume, to generate a real - time intelligent scheduling plan:

[0072] Set the number of visiting ships m, cargo weight Q, the number of terminal berths α, and the loadable and unloadable volume β;

[0073] For each ship k (k = 1, 2,..., m), calculate the dock it visits according to the parameters until all the currently visiting ships enter the dock for loading and unloading;

[0074] Repeat the previous two steps, calculate the actual route L and the loading and unloading time t of each ship during navigation, record the optimal solution of the current iteration number and make updates; to find the optimal path and generate a ship scheduling plan.

[0075] S2: The applicant logs in to the application module of the ship berthing system and submits a berthing application text to the ship berthing system.

[0076] Generally, the system entrance of the ship berthing system includes other interactive interfaces such as the business handling platform of the WeChat official account. In this embodiment, taking the WeChat official account as an example, the applicant needs to follow the WeChat official account or register and log in to the system account to log in to the ship berthing system. If it is a temporary outsider, the administrator needs to maintain and bind the supplier, and then the system automatically generates a token verification (token verification). Within the valid time of the token, it can pass the security verification and log in to the system.

[0077] Generally, the applicant submits a berthing application text including manually filling out an application form, or the applicant submits the general content and then the system extracts and automatically fills out the application form. Specifically, the steps for the applicant to manually fill out the application form include: first, conduct shipping registration, and then manually select or fill in information such as ship type, ship type, cargo information, planned berthing, departure date, and crew members on board.

[0078] S3: The ship berthing system extracts the key information in the berthing application text and automatically generates a ship berthing application form.

[0079] Specifically, the applicant submits the berthing application text to the ship berthing system. The ship berthing system automatically extracts the key information in the berthing application text and fills it into the blank application form to generate a ship berthing application form. The specific extraction and filling process is as described in step S1 and will not be elaborated here.

[0080] Optionally, it also includes judging the accuracy of the key information:

[0081] Set the threshold of the key information; the threshold is used to determine the confidence level of the model prediction result, to avoid filling incorrect information into the application form due to low-probability prediction. The threshold range is 0 to 1 (probability value), and the specific size can be set according to the actual situation. The larger the threshold, the higher the accuracy of the key information, but the lower the practicality of the extracted key information; the smaller the threshold, the lower the accuracy of the key information.

[0082] The ship berthing system calculates the prediction results of the key information; specifically, the specific calculation rules for the prediction results: According to the training principle of the CRF conditional random field model, given the entity category X, for each annotation sequence Y, the conditional probability distribution of the annotation sequence Y is P(Y|X).

[0083] Judge the magnitude relationship between the prediction result and the threshold. When the prediction result is greater than the threshold, the ship berthing system automatically generates a ship berthing application form; specifically, according to the probability calculation result, perform a reverse order sorting on the conditional probability distributions calculated for multiple annotation sequences Y, and the one with the highest probability is the prediction result corresponding to the entity category X. If the prediction result is less than the threshold, the ship berthing system determines that the key information is invalid, and the applicant needs to fill in the application form manually.

[0084] S4: Push the ship berthing application form to the client of the approver. The approver approves the ship berthing application information and generates an approval result, and feedbacks the approval result to the applicant's client.

[0085] Specifically, the ship berthing application form is pushed to the client of the approver, and the approver's client receives a message notification in real time. The client includes methods such as mobile phones and computers, and the message notification methods include: text, cards, pictures, etc.

[0086] By setting up multiple approval nodes, the approval requirements and authorities of each node are different, and different optional items are set according to the current approval node. The specific rules are as follows: After receiving the ship docking application submitted by the applicant, complete the approval of the docking application in sequence according to the pre-set three-level approval process.

[0087] As Figure 2 shown, it shows the ship docking approval process schematic diagram provided by this embodiment; this embodiment takes three-level approval as an example. The first-level approval checks the compliance of the goods: The applicant designates a first-level approver, and the first-level reviewer corrects and completes the review of simple information such as the types and information of the goods on the ship docking application form; or the system automatically checks whether the goods are compliant, and then the approver makes corrections or rejects them to ensure the compliance of the docked ship. If the application passes, the application requests the second-level approval; if the application is rejected, the approval process ends.

[0088] The second-level approval corrects the planned berthing and departure times of the visiting ship, completes the review of the first-level approval matters, and provides decision-making opinions on the docked ship. If the application passes, the application form requests the third-level approval; if the application is rejected, the approval process ends. The second-level approver is designated by the system.

[0089] Level 3 approval is the final, comprehensive review process: it comprehensively examines incoming vessels, generates a final approval result, and completes the docking application approval process. The approval result (approved / rejected / needs revision) is then fed back to the applicant, who then chooses to proceed to the dock. Level 3 reviewers are assigned by the system.

[0090] S5: Acquire visiting ship information in real time, input the ship information into the ship berthing system, and the ship berthing system generates a ship scheduling plan.

[0091] Collect real-time ship information of visiting ships, including the current position of the ship, ship size, voyage draft and other information, monitor the ships in real time, and obtain information data of all visiting ships at the current terminal; input the visiting ship information data into the ship berthing system, which considers the actual visiting ship information and the remaining berths and loading and unloading volume of the current terminal to generate a real-time intelligent scheduling plan.

[0092] S6: Feedback the ship dispatch plan to the applicant and the terminal management personnel client.

[0093] Specifically, the ship dispatch plan (berth allocation, time schedule) is fed back to the applicant and terminal management client in real time. Specifically, the applicant client receives WeChat public account messages, in-system notifications, and SMS reminders; the terminal management client receives pop-up reminders from the terminal management platform and email notifications. Specifically, the push notification content includes: berth number, estimated berthing / unberthing time, loading and unloading precautions (such as the need for isolated areas for dangerous goods), and a dispatch plan route map (driving route within the terminal).

[0094] The applicant will navigate the vessel to the designated berth according to the dispatch plan. Optionally, the vessel's berthing system will provide real-time navigation assistance (e.g., electronic charts with optimal routes marked). Optionally, if any issues arise during the dispatch process, the applicant may submit an emergency adjustment request through the vessel's berthing system.

[0095] Terminal managers direct ships to dock according to the dispatch plan and coordinate the deployment of loading and unloading equipment (such as cranes and tugboats). Optionally, terminal managers can update the terminal berth status to the system in real time to ensure data synchronization.

[0096] Optionally, some vessels require special berthing handling from the terminal management staff, including vessels not participating in intelligent scheduling or vessels leaving their berths directly for special reasons. Vessels not participating in intelligent scheduling are manually assigned berths by the terminal management staff, and the system records the operation log. For vessels leaving their berths directly for special reasons, the system automatically generates a quick unmooring instruction. The terminal management staff electronically authorizes the vessel to be released from its mooring, and after system scheduling, the vessel can be directly unmoored through the system without going through the full safety monitoring process.

[0097] Optionally, it further includes S7 to transmit the ship berthing / departing data back to the basic database.

[0098] Specifically, after the ship berths / departs, the applicant and the terminal management staff need to click to confirm on the client side, and the system records the actual time and status. In addition, the terminal berth data provided by the department is uploaded to the basic database in a timely manner to achieve closed-loop management and provide data statistics and data feedback. The terminal berth data includes the basic information of the terminal: the newly added / repaired terminal berth data (location, capacity, equipment configuration) is uploaded to the basic database by the management department through Excel.

[0099] Optionally, it further includes real-time monitoring of the terminal safety; specifically, visual safety monitoring and ship positioning are used to monitor the safety of the ships berthed at the terminal in real time. When problems occur, the results are feedback in a timely manner, and an abnormal alarm processor is provided. Devices such as sensors and terminal cameras dynamically collect the current images of the ships and monitor abnormal situations of the ships, including abnormal problems such as the current position of the ship, abnormal loading and unloading, personnel falling into the water, and ship fires.

[0100] Optionally, an abnormal alarm and processing mechanism is set up, supplemented by dynamic recognition and abnormal behavior monitoring algorithms, and an alarm is triggered in a timely manner when problems such as ship abnormalities or abnormal loading and unloading occur; the abnormal alarm notification is comprehensively processed, and the current alarm information is feedback to the security personnel in a timely manner, and the alarm information is provided by means of message notification, SMS, email, etc.

[0101] In summary, the safety operation steps provided in this embodiment are as follows: First, the applicant submits an application form to the ship berthing system, and the approver approves it in turn; after the approval, the visiting ship enters the terminal. The current position, ship volume, draft of the voyage, etc. of the visiting ship on site and the utilization situation of the current terminal and the remaining berth data are transmitted to the ship berthing system by the on-site terminal equipment monitoring device and terminal sensor device; the ship berthing system generates a ship scheduling plan; the applicant navigates the ship to the designated berth according to the scheduling plan; the terminal safety monitoring module monitors the safety of the ships berthed at the terminal in real time, including the ship status, cargo status, safety status of the unloading personnel, etc. When problems occur, the results are feedback in a timely manner, and an abnormal alarm processor is provided; if a special ship appears, special treatment is carried out.
