[0023] The present invention provides a ship navigation monitoring management method, device, equipment and storage medium, which are described below respectively.

[0024] Figure 1 A schematic diagram of an embodiment of the ship navigation monitoring management method provided by the present invention is shown in FIG. Figure 1 As shown, the ship navigation monitoring management method includes: S101, obtaining RFID identity information and AIS dynamic information of the target ship, where the AIS dynamic information includes the current position, real-time speed and real-time heading of the target ship; S102, verifying the RFID identity information of the target ship and generating identity authentication information; S103, determining the preset route data of the target ship according to the identity verification information, calculating the current position deviation, real-time speed deviation and real-time heading deviation of the target ship according to the preset route data of the target ship and the AIS dynamic information, and generating navigation deviation data; S104: Generate a traffic management strategy for navigation monitoring of the target ship based on the identity authentication information and the navigation deviation data.

[0025] It should be noted that the RFID identity information is obtained through the RFID chip card installed on the target ship. The RFID chip card is pre-issued and installed for each ship. The chip card stores the static identity information of the ship, including ship ID, ship name, ship type, ship owner information, ship weight, empty draft, full load draft, headroom, ship size, maximum speed and wind resistance level, etc. When the ship approaches the monitoring area, the wireless radio frequency technology is used to read the information of the RFID chip card.

[0026] It should be further explained that AIS dynamic information is the dynamic navigation information of the ship collected through the ship automatic identification system. AIS dynamic information includes ship ID, current time, departure port ID, destination port ID, cargo, cargo weight, forward draft, stern draft, ship's navigation speed, position longitude and latitude coordinates, and ship's direction and latitude.

[0027] It should be further explained that, in this embodiment, a database is pre-designed to store the information on the RFID chip card and the route information corresponding to each ship. At the same time, the information on the RFID chip card obtained in real time is integrated with the AIS dynamic information and stored in the database to reflect the latest status of the ship.

[0028] It should be further explained that the ship navigation monitoring management method in this embodiment is applied to a ship monitoring management system, and the ship monitoring management system includes hardware components and software structures, wherein the hardware components include a radio frequency identification data reading and writing device installed at the channel gate, which is responsible for reading and writing the information of the radio frequency identification tag; an AIS receiver installed near the ship lock, which is used to receive the AIS signal transmitted by the ship; a central monitoring and control component, which is used to integrate and process radio frequency identification and AIS data, and display the ship information, actual navigation route and preset navigation route in a visual image. The software structure includes a database and a data processing structure layer, and the data processing structure layer is used to process and analyze the received data in layers. First, the received data is pre-processed by collating, filtering, formatting, etc., and then the RFID identity information data is fused with the AIS, and the fused data is compared, analyzed and calculated. Finally, the database is updated in real time according to the fused data. In addition, the data in the database is accessed, used and visualized through the central monitoring and control component.

[0029] Specifically, the read RFID identity information is compared with the ship identity information in the preset database to generate a verification result. According to the verification result, the preset route data of the corresponding ship is found in the database, and the preset route data is compared with the current AIS dynamic data. According to the data deviation and identity verification result between them, it is determined whether the target ship can pass and the ship's navigation adjustment strategy.

[0030] This embodiment obtains RFID identity information and AIS dynamic information, authenticates the target ship according to the RFID identity information, analyzes the dynamic navigation route of the ship through the AIS dynamic information, calculates the deviation between the current navigation route of the ship and the preset navigation route, obtains the ship's passage signal according to the identity authentication result, determines the ship's navigation adjustment signal according to the deviation of the navigation route, and monitors and manages the target ship according to the passage signal and the navigation adjustment signal. By processing and analyzing RFID data and AIS data, the dynamic navigation data of the ship is accurately calculated to achieve real-time and accurate monitoring and management of the ship.

[0031] In some embodiments of the present invention, Figure 2 As shown, Figure 2 The present invention provides Figure 1The flowchart of an embodiment of step S103 in the embodiment includes: S201, generating actual route data of the target ship according to the AIS dynamic information of the target ship; S202, based on the geographic hashing technology, processing the preset route data and the actual route data respectively to generate two-dimensional preset route vector data and two-dimensional actual route vector data; S203, calculating the current position deviation of the target ship according to the difference in coordinate information of the current position in the two-dimensional preset route vector data and the two-dimensional actual route vector data; S204, calculating the real-time speed deviation of the target ship according to the difference between the preset speed limit of the current channel gate of the target ship and the current speed of the target ship; S205, calculating the real-time heading deviation of the target ship according to the position information of the target ship at the current moment and the previous moment in the two-dimensional preset route vector data and the two-dimensional actual route vector data, combined with the real-time heading of the target ship.

[0032] It should be noted that each ship has its corresponding preset route data, and the preset position coordinate information of the ship at the current moment can be determined according to the navigation route; a speed limit is set for each channel gate according to the ship flow rate and the width of the gate. When the current speed of the target ship exceeds the speed limit of the current channel gate, the target ship needs to reduce the current speed; when the current speed of the target ship is lower than the speed limit of the current channel gate, and the speed deviation value is greater than the preset threshold, the target ship needs to increase the current speed to avoid channel congestion. At the same time, it is necessary to combine the maximum speed limit of the target ship, and the current speed of the target ship cannot exceed its maximum speed limit.

[0033] Specifically, based on the real-time AIS dynamic information of the target ship, the route of the target ship in actual navigation is constructed; geographic hashing technology is a technology that converts geographic coordinates into hash values, and through geographic hashing, the route data is converted into two-dimensional vector data.

[0034] This embodiment uses geographic hashing technology to convert both the actual route data and the preset route data of the target ship into two-dimensional vector data. Based on the converted two-dimensional vector data, the position deviation and heading deviation can be simply and accurately calculated. Combined with the speed deviation, accurate data support is provided for the navigation adjustment strategy of the target ship.

[0035] In some embodiments of the present invention, Figure 3 As shown, Figure 3 The present invention provides Figure 2 The flowchart of an embodiment of step S203 in the embodiment includes: S301, calculating the straight-line distance between the position coordinates of the two-dimensional preset route vector data and the position coordinates of the two-dimensional actual route vector data at the current moment, and generating a route position deviation; S302, calculating the straight-line distance between the position coordinates of the two-dimensional actual route vector data at the current moment and the position coordinates of the channel gate, and generating a ship lock distance deviation; S303. The route position deviation and the lock distance deviation constitute the current position deviation.

[0036] Specifically, the deviation between the current position of the target ship and the ideal position it should be in and the distance between the current position and the channel gate are combined to form the current position deviation. This current position deviation is a comprehensive indicator used to evaluate the relationship between the current navigation state of the ship and the ideal state and the relative position between the channel entrance. According to the current position deviation, the navigation direction and speed of the ship are adjusted to correct its deviation. At the same time, the information of the target ship entering the channel gate is determined according to the lock distance deviation.

[0037] This embodiment provides accurate data support for ship monitoring and management by calculating the deviation between the current position of the target ship and the preset channel position and the distance from the channel gate, ensuring the safe and efficient navigation of the ship, thereby avoiding potential safety risks and delays.

[0038] In some embodiments of the present invention, Figure 4 As shown, Figure 4 The present invention provides Figure 2 The flowchart of an embodiment of step S204 in the embodiment includes: S401, calculating the preset heading vector values ​​at the current moment and the previous moment based on the two-dimensional preset route vector data; S402, calculating the actual heading vector values ​​at the current moment and the previous moment based on the two-dimensional actual route vector data; S403, calculating the current vector angle between the preset heading vector value and the actual heading vector value; S404: Calculate the heading deviation of the target ship according to the current vector angle and the real-time heading of the target ship.

[0039] Specifically, the time difference between the current moment and the previous moment is taken according to the actual route conditions, and the vector directions of the line segments from the current time point to the previous time point of the preset route and the actual route are calculated respectively. At this time, two line segments with vector directions are generated, and then the angle between the two vector line segments is calculated, which is the current vector angle. The calculation formula of the vector angle is: , in, is the current vector angle between the preset heading vector value and the actual heading vector value, is the preset heading vector value, that is, the vector value from the previous moment to the current moment of the preset route. is the actual heading vector value, that is, the vector value from the previous moment to the current moment of the actual route, is the dot product of the preset heading vector value and the actual heading vector value, and They are and Vector module of .

[0040] Furthermore, since the target ship also has a heading deviation, after calculating the deviation angle from the previous moment to the current moment, it is necessary to superimpose the current heading deviation on the current vector angle to obtain the accurate heading deviation of the target ship.

[0041] This embodiment calculates the current course deviation of the target ship by comparing the preset route and the actual route of the target ship, thereby providing data support for the navigation adjustment strategy of the target ship.

[0042] In some embodiments of the present invention, Figure 5 As shown, Figure 5 The present invention provides Figure 4 The flowchart of an embodiment of step S404 in the embodiment includes: S501, converting the real-time heading data of the target ship into vector data to generate a real-time navigation vector; S502, calculating the angle between the real-time navigation vector and the current heading vector in the two-dimensional preset route vector data to generate a future vector angle; S503: Calculate the course deviation of the target ship according to the future vector angle and the current vector angle.

[0043] Specifically, according to the current real-time heading and speed of the target ship, a real-time navigation vector is obtained to represent the current navigation direction of the target ship. The angle between the navigation vector and the current heading vector in the two-dimensional preset route vector data is calculated. The sum of the future vector angle and the current vector angle reflects the degree of deviation of the target ship's route from the expected route when it is sailing at the current heading and speed.

[0044] This embodiment monitors and manages the target ship by calculating the deviation of the real-time course.

[0045] In some embodiments of the present invention, the heading deviation of the target ship is calculated according to the future vector angle and the current vector angle, and the calculation formula is: , in, is the heading deviation of the target ship, and is the weight coefficient, is the current vector angle, is the future vector angle, and It is an angle with a positive or negative sign, and its positive or negative sign indicates the direction of deviation from the preset route.

[0046] It should be noted that the actual route of the target ship is compared with the preset route of the target ship, and the angle of deviation is calculated. The preset route is used as a reference, and its positive or negative sign is determined according to the direction of deviation. Then the future vector angle is calculated, that is, the future heading of the ship is judged according to the heading at the current moment, and compared with the preset route of the target ship, and the angle of deviation is calculated. The preset route is also used as a reference, and its positive or negative sign is determined according to the direction of deviation. In addition, , The weight coefficient can be adjusted according to the actual channel environment data, such as wind speed, water flow rate, etc. In this embodiment, when the channel environment is ideal, the weight coefficient is set to , The weight coefficients are all 1, the calculated vector angle of the target ship's current deviation from the preset course is -15, the calculated future vector angle of the target ship is +15, and the calculated heading deviation is 0, which means that the target ship has adjusted its heading and there is no need to send a signal to adjust the ship's heading.

[0047] This embodiment combines the course deviation of the target ship that has been traveled with the current course deviation as a judgment of the course deviation, thereby more accurately calculating the navigation deviation of the ship.

[0048] In some embodiments of the present invention, Figure 6 As shown, Figure 6 The present invention provides Figure 1 The flowchart of an embodiment of step S104 in the embodiment includes: S601, determining a passage signal of a target ship according to identity authentication information; S602, generating a navigation adjustment signal according to the position deviation, speed deviation and heading deviation; S603: Manage the target ship according to the passage signal and navigation adjustment signal of the target ship.

[0049] Specifically, the obtained identity authentication information is compared with the ship information registered in the database, and whether the target ship can pass is determined based on the comparison information, such as whether the target ship ID exists, whether it is overloaded, whether the target ship size is consistent with the gate, etc. For ships with safety hazards, corresponding real-time warnings are issued through the central monitoring and control component; based on the calculated position deviation, speed deviation and heading deviation, the ship's adjustment signal is determined and sent to the target ship, and the ship's actual route data and preset route data are visualized through the central monitoring and control component in combination with an electronic map. For ships with safety hazards, corresponding real-time warnings are issued, and corresponding measures are taken according to the warning information.
