Description

Technical Field

[0001] The present invention relates to the field of maritime emergency information support and the technical field of ship-shore integrated system, and in particular to a ship-shore integrated information support system for maritime emergency response. Background Art

[0002] The maritime emergency response process is complex, involving too many risk factors, and the situation at the emergency site is dynamic and changeable. The formulation of a maritime emergency search and rescue plan, as one of the important links in maritime emergency response, requires comprehensive information on the hydrological and meteorological conditions, rescue forces, and the current status of emergency targets at the maritime emergency response site. Existing maritime emergency information support systems mostly provide marine meteorological information support for a certain sea area, lack the extraction of information on the status of emergency rescue forces and emergency targets, and their information display methods lack pertinence to the situation at the emergency site, and are unable to integrate and plot various information on the emergency site. These information support systems mostly operate as independent entities on the ship and the shore, and cannot guarantee that shore-based rescue decision makers can obtain emergency site situation information in a timely manner during the emergency response process, affecting the efficiency of maritime emergency response decision-making. Summary of the Invention

[0003] In response to the above technical problems, a ship-shore integrated information support system for maritime emergency response is provided.

[0013] The emergency target status data includes the location information of the suspected target point and the moving speed and moving direction data of the suspected target point.

[0014] Furthermore, in the shore-based data acquisition module:

The mapped icon moves with the movement of the mother ship. The wind information is represented by a long arrow. The arrow and the text information on the arrow will change with the change of wind direction. The arrow icon is used to represent the surface flow information. The direction of the arrow changes with the flow direction. When mapping, the area around the mother ship is divided into 6 parts according to the angle, that is, each icon occupies a 60-degree sector area, and the fan where the wind direction in the current environment is located is mapped. The system uses the fan-shaped area as a reference to calculate the positions of the current, wave, temperature, salinity and density icons in sequence, and the plot display is refreshed once a second. In addition, the system will plot the emergency target position and the ROV position and operating depth on the electronic chart. Double-click the emergency target, mother ship, ROV, salinity, density and temperature icons to view specific information. Move the mouse to the wind, current and wave icons to view the specific numerical information of the wind, current and wave at the current position. Among them, the emergency scene situation plotting information includes: wind speed, wind direction, seawater density, seawater salinity, seawater surface temperature, sea surface current velocity, sea surface current direction and ROV operating depth.

[0026] Furthermore, in the data processing module:

[0027] The data extraction and processing for visualizing the marine environment status at the emergency site are as follows: the ship-shore integrated information support system extracts data at different depths and different time periods from the database according to the different marine environment status data to be visualized, determines the marine environment status data points for visualization by calculation based on the number of data points selected for display, and obtains the statistical value of the marine environment status data by statistically analyzing the values ​​and number of marine environment status data points;

[0028] Data acquisition for situation integration: Before displaying the integrated situation, the ship-shore integrated information support system uses MySQL statements to sort ocean status data, emergency force status data, and emergency target status data from the database by time, and obtains the latest data at the current time. The ocean status data also extracts sea surface velocity, sea surface temperature, and the deepest current velocity and temperature information.

[0029] The data acquisition used for situation plotting is as follows: before the situation plotting display is performed, the ship-shore integrated information support system uses MySQL statements to sort the ocean status data, emergency force status data and emergency target status data from the database by time, and obtains the latest data at the current time; the ocean status data also extracts sea surface current velocity, sea surface temperature, sea surface salinity and sea surface density information, and the emergency status data extracts the ROV's operating depth information.

[0030] Furthermore, the number of data points selected for display is used to determine the ocean environment status data points for visualization by calculation, specifically:

[0031] For the ocean environment status data set A within the current time t, water depth d, and time period T, the number of displayed data selected is n. For the i-th data point, the data point to be displayed p is obtained by the following formula i Time t i ;

[0032] t i =ti*(T / n),(i=1,2,K,n)

[0033] According to the determined time t i , get the time t i The closest data point p i , and finally get the data point set P(p1,p2,K,p n );

[0034] The statistical analysis of the values ​​and numbers of the ocean environment status data points to obtain the statistical values ​​of the ocean environment status data is specifically:
