Description

Technical Field

[0001] The present invention relates to the technical field of Yangtze River shipping, and in particular to an intelligent waterway planning and safety supervision system driven by Yangtze River shipping big data. Background Art

[0002] As an important inland waterway in my country, the Yangtze River has busy shipping business, but traditional waterway planning and safety supervision methods have many limitations. At present, the route planning of ships from the starting port to the destination port mainly depends on the captain's past experience in water navigation, the changes in the water level of the channel, and the information provided by the electronic navigation chart. The captain decides the navigation path on his own. This method makes the safety of the ship largely dependent on the captain's experience and the accuracy of the information. If there are errors in information acquisition or improper decisions, it may pose a threat to the safety of the ship. For regulatory agencies, given the uncertainty of waterway information and the subjectivity of captains, regulatory agencies can only implement safety supervision on key waters and specific ships based on general standards, but cannot carry out detailed route planning and safety supervision for all ships based on specific circumstances. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent waterway planning and safety supervision system driven by Yangtze River shipping big data to solve the problems raised in the above-mentioned background technology.

[0004] In view of the above problems, the technical solution proposed by the present invention is: An intelligent waterway planning and safety supervision system driven by big data of Yangtze River shipping, comprising a ship information collection system, a waterway information collection system, a meteorological information collection system, a port information collection system, an information processing system, an early warning system, and a historical information collection system. The ship information collection system collects information on the position, course, speed, ship type, and draft of the ship; the waterway information collection system collects topography, water depth, and hydrological information of the waterway; the meteorological collection system collects meteorological information of the waterway; the port information collection system collects information on the position, number of berths, and water depth of the port; the historical information collection system collects traffic control rules for the route and historical navigation records of the route; the information processing system collects, analyzes, and processes the information collected by the ship information collection system, the waterway information collection system, the meteorological information collection system, the port information collection system, and the historical information collection system, and plans the ship's waterway; and the early warning system provides early warnings for ships that deviate from the planned waterway.

[0005] As a preferred technical solution of the present invention, the ship information collection system includes a ship automatic identification system and an ultrasonic sensor installed on the ship. The ship automatic identification system collects and sends the ship's position, heading, speed, and ship type information to the information processing system, and the ultrasonic sensor collects and sends the ship's draft depth information to the information processing system.

[0006] Specifically, the ship information collection system is used for information exchange between ships and between ships and shore-based facilities. The basic information it transmits includes static information of the ship (such as Maritime Mobile Service Identity (MMSI), ship name, call sign, ship type, ship size, etc.), dynamic information (such as ship position, heading, speed, navigation status, etc.) and voyage-related information (such as cargo type, destination port, etc.).

[0007] As a preferred technical solution of the present invention, the waterway information collection system includes a number of multi-beam bathymetric systems, side-scan sonars, lidars, water level meters, and current meters arranged on the waterway. The multi-beam bathymetric systems, side-scan sonars, and lidars acquire and send the topography and water depth data of the waterway to the information processing system. The water level meters and current meters acquire and send the water level changes and water flow rates of the waterway to the information processing system.

[0008] Specifically, multi-beam bathymetric systems, side-scan sonars and lidar are used to obtain data on the topography and water depth of the waterway. These data can accurately depict the contours of the waterway, including information such as water depth changes, reef locations, and the range of shoals.

[0009] As a preferred technical solution of the present invention, the meteorological information collection system includes a meteorological monitoring station, and the meteorological monitoring station obtains and sends the wind direction, wind speed, temperature and precipitation information of the waterway to the information processing system.

[0010] As a preferred technical solution of the present invention, the port information collection system includes a joystick and a geographic information system, and the joystick and the geographic information system acquire and send images of the port to the information processing system.

[0011] Specifically, through image analysis, we can collect information on the port’s location, number of berths, berth water depth, terminal facility type, and cargo throughput. Understanding port data will help to rationally plan the channels for ships entering and leaving the port.

[0012] As a preferred technical solution of the present invention, the historical information collection system includes a maritime bureau, and the maritime bureau sends the traffic control rules of the route and the historical navigation records of the route to the information processing system.

[0013] As a preferred technical solution of the present invention, the information processing system includes a waterway geographic information model, a data analysis module, and a data processing module established in a dispatching center. The waterway geographic information model establishes a three-dimensional model of the waterway based on the information collected by the waterway information collection system; the data analysis module obtains the navigation behavior of the ship and the ship density of the waterway based on the information collected by the ship information collection system, and the data analysis module obtains the location of the port, the number of berths, and the berth water depth information based on the information collected by the port information collection system; the data processing module plans waterways for ships based on the data collected and analyzed by the waterway geographic information model, the data analysis module, the meteorological information collection system, and the historical information collection system.

[0014] Specifically, by combining the ship position and speed data to analyze the congestion of the waterway, the smoothness of the waterway can be evaluated by calculating indicators such as ship density and ship spacing.

[0015] Specifically, the data processing module uses the shortest path algorithm (such as the Dijkstra algorithm) to plan the optimal navigation path for the ship while taking into account geometric constraints such as channel depth, width, curvature, and physical constraints such as hydrology and meteorology.

[0016] Specifically, the data processing module is also equipped with a dynamic path adjustment algorithm. Since the channel conditions (such as changes in water depth, sudden changes in water flow, etc.) and the ship status (such as ship failures, changes in cargo loading and unloading time, etc.) are dynamically changing, the dynamic path adjustment algorithm can be used to adjust the ship's channel in a timely manner. For example, when a shoal appears in a certain area of ​​the channel, resulting in insufficient water depth, the system can re-plan the ship's path in a timely manner and guide the ship to bypass the dangerous area. This dynamic adjustment can be achieved based on real-time data and prediction models. The prediction model can predict changes in channel conditions and ship status based on historical data and current trends.

[0017] As a preferred technical solution of the present invention, the early warning system includes an early warning module, which receives the channel deviation early warning information sent by the data processing module, and the early warning module also sends the channel deviation early warning information to the ship.

[0018] Specifically, the information collected by the ship's automatic identification system is combined with the difference between the ship's actual navigation trajectory and the recommended navigation trajectory, and an early warning is issued.

[0019] In another aspect, the present invention provides a method for an intelligent waterway planning and safety supervision system driven by Yangtze River shipping big data, comprising the following steps: Step 1: Rationally arrange multi-beam bathymetric systems, side-scan sonar, lidar, water level gauges, current meters, and meteorological monitoring stations along the Yangtze River waterway to ensure that the required data can be collected comprehensively and accurately. At the same time, complete the development and testing of data interfaces with the databases of relevant departments to ensure the stability and security of data transmission to the dispatching center; Step 2: Build a data storage platform according to the distributed storage architecture, configure various parameters of the data management system, import the initial waterway geographic information data and other basic data, and set up data backup and recovery mechanisms; Step 3: Use the information collected by multi-beam bathymetry system, side-scan sonar, lidar, water level meter, current meter, meteorological monitoring station, automatic ship identification system, ultrasonic sensor, meteorological monitoring station, joystick and geographic information system, and cooperate with the channel geographic information model to establish a channel model, and use the information collected by meteorological monitoring station, water level meter, current meter, automatic ship identification system, ultrasonic sensor, and the channel model established by the channel geographic information model to plan the channel for the ship; Step 4: Use the historical shipping data sent by the Maritime Safety Administration to train the data mining algorithm and machine learning model, and continuously optimize the parameters of the waterway geographic information model through methods such as cross-validation to improve the accuracy and generalization ability of the waterway geographic information model; Step 5: Conduct a trial run of the system in some waterway areas, conduct a comprehensive test of data collection, analysis, early warning, and visualization functions, and promptly identify and resolve system problems; Step 6: After the system passes the trial operation acceptance, it will be officially put into operation in the entire Yangtze River basin. A system operation monitoring mechanism will be established, and user feedback will be collected regularly. According to the development of shipping business and technological progress, the system will be continuously upgraded and improved, such as updating data analysis models and expanding the scope of data collection.

[0020] Compared with the prior art, the beneficial effects of the present invention are: the intelligent waterway planning and safety supervision system driven by the Yangtze River shipping big data can realize the scientific planning and efficient utilization of ship waterway resources, significantly improve the level of shipping safety supervision, and ensure the safe, orderly and smooth development of waterway shipping.
