Description

Technical Field

[0001] The present invention relates to the field of underwater communication technology, and in particular to a method for fusion display of underwater platform position and state. Background Art

[0002] With the continuous development of marine resources and marine scientific research, the strategic position of underwater mobile platforms in marine operations has become increasingly important. Underwater platforms such as autonomous underwater vehicles (AUVs) and remotely operated underwater vehicles (ROVs) have been widely used in scientific and engineering tasks such as seabed topography mapping, underwater structure inspection, and environmental monitoring. Most of these tasks need to be carried out in complex and extreme underwater environments, which places strict requirements on the platform's high-precision positioning, real-time status perception, and communication link stability. However, due to the particularity of the underwater environment, including the variability of acoustic propagation, frequent signal attenuation, and the impact of complex terrain on communication, traditional positioning and communication technologies have obvious limitations in deep-sea or long-distance operations.

[0003] The shortcomings of traditional technologies in terms of accuracy and reliability have made it necessary to develop an integrated technology with accurate geographic information support capabilities and the ability to display the location and communication status of underwater platforms in real time.

[0004] Therefore, it is necessary to provide a method for fusion display of underwater platform position and status to solve the above technical problems. This method provides real-time spatial information of the platform itself through high-precision positioning, and at the same time clarifies the geographical location and connection status of the communication object, so as to fully support the platform's task execution in complex environments; by realizing the deep integration of platform positioning and communication status, this type of technology can significantly enhance the perception capability, communication efficiency and operational reliability of underwater platforms in dynamic environments, providing important technical support for complex underwater operations. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a method for fusion display of underwater platform position and status. The method organically combines high-precision nautical charts, real-time position parameters of underwater platforms, working sea depth and communication status information through a software interface, providing comprehensive geographic information support and communication status monitoring for marine operations. The core of the system is based on high-precision nautical chart data and advanced data processing algorithms to achieve comprehensive monitoring and optimized control of underwater platforms. The interface displays the geographical distribution of the current sea area, and marks the "source" and "receiver" positions of the underwater platform with prominent icons, so that the operator can intuitively grasp its geographical location and working area.

[0006] Through the comprehensive application of multiple technologies, the present invention realizes the integrated display of the position and status of an underwater platform. By adopting the latest high-precision nautical chart data, it provides an accurate geographical reference framework, significantly improving the positioning accuracy of the underwater platform in complex environments. At the same time, it integrates multi-source sensor data, including position, speed, direction, and environmental parameters, and uses data fusion technology to generate comprehensive status information of the platform to meet the real-time monitoring requirements in dynamic environments. The system presents the connection status between the platform and each communication node in real time through the nautical chart interface, enabling the operator to intuitively grasp the health status of the communication link and handle abnormalities in a timely manner to ensure the continuity of tasks and the safety of operations. In addition, the system has a data storage function, allowing the operator to independently import nautical charts of the sea area and call them according to actual needs for more accurate mission planning and adjustment, improving the flexibility and adaptability of the system.
