[0002] The huge energy and momentum impulse caused by internal waves are catastrophic to oil and gas platforms, and maritime operation safety accidents caused by internal waves are not uncommon.

[0003] The traditional domestic internal wave early warning methods mainly include deploying monitoring buoys and guard ships in the upstream sea area, transmitting the observed data back using a transmission module, and then carrying out internal wave identification and early warning based on the observed data. However, both methods have drawbacks in terms of observed data transmission and operation and maintenance. Summary of the Invention

[0004] Aiming at the problems of observed data transmission and operation and maintenance in the above internal wave monitoring and early warning method, the purpose of the present invention is to provide a method and system for internal wave monitoring and early warning based on ground wave radar, which can improve the observed data transmission efficiency, make the operation and maintenance of the early warning system more convenient and fast, and reduce the operation and maintenance costs.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] In a first aspect, the present invention provides a method for internal wave monitoring and early warning based on ground wave radar, including the following steps:

[0007] Deploy a ground wave radar device at a preset position of an oil and gas platform, and use the ground wave radar device to obtain observed data of the surface sea state;

[0009] Make early warning information according to the internal wave parameters and the time when the internal waves are expected to reach the oil and gas platform, and push the early warning information to the operators of the oil and gas platform.

[0010] Further, when deploying the ground wave radar device at the preset position of the oil and gas platform, determine its deployment position according to the internal wave propagation characteristics of the sea area, deploy the ground wave radar device on the railing or corridor on the incoming side of the internal wave, and the normal direction of the ground wave radar faces the incoming direction of the internal wave;

Obviously, the described embodiments are some but not all of the embodiments of the present invention.

[0040] Internal waves in the ocean pose a huge threat to the safe production of oil and gas platforms. Conducting real-time monitoring and warning of internal waves in the ocean is of great significance. The traditional domestic methods for internal wave warning mainly include deploying monitoring buoys and guard ships in the upstream sea area, using a transmission module to transmit the observed data back, and then conducting internal wave identification and warning based on the observed data. However, due to poor signal at sea, it is difficult to transmit the observed data back, the transmission efficiency of the observed data is not high, and the offshore monitoring system also has the problem of high operation and maintenance costs.

[0041] As an emerging observation means, while the ground wave radar uses high-frequency electromagnetic waves to detect the surface sea state in real time, it also completes the transmission of the observed data, without the need to be equipped with an additional observed data transmission module, which can solve the problem of transmitting the observed data of monitoring buoys and guard ships. The ground wave radar can monitor a large area of the sea area, and the detection distance can reach 100-190 km. Moreover, the ground wave radar can be arranged on the oil platform, and the daily operation and maintenance and routine fault repair of the ground wave radar system can be completed by the staff of the oil and gas platform, making the operation and maintenance of the warning system more convenient and fast, and the cost is relatively low.

[0042] Based on this, in some embodiments of the present invention, a method for monitoring and warning internal waves based on ground wave radar is provided. The method includes: deploying ground wave radar equipment on an oil and gas platform, and identifying internal waves using the observation data obtained by the ground wave radar equipment; determining internal wave parameters according to the internal wave identification results, and calculating the time when the internal wave is expected to reach the oil and gas platform according to the internal wave parameters; making a warning message according to the internal wave parameters and the expected arrival time, and pushing the warning message to the operators of the oil and gas platform. The present invention can solve the problem of observation data transmission in traditional warning and monitoring methods, improve the efficiency of internal wave warning, make the operation and maintenance of the warning system more convenient and fast, and reduce the operation and maintenance costs.

[0043] Correspondingly, in some other embodiments of the present invention, a system, device and medium for monitoring and warning internal waves based on ground wave radar are provided.

Filter the sea current velocities of each unit in the space of the ground wave radar, separate the internal wave-induced velocity components, thereby identify internal waves, and extract the third internal wave propagation direction, the third distance between the internal wave and the oil and gas platform, and the third internal wave propagation speed.

[0062] Furthermore, in the above step S22, performing fusion comparison on the internal wave identification results obtained by different analysis methods means performing fusion comparison on the internal wave parameters identified by the three different analysis methods in step S21, that is, taking the average of the three obtained internal wave propagation directions, the distances between the internal wave and the oil and gas platform, and the internal wave propagation speeds as the final internal wave parameters, including the internal wave propagation direction, the distance between the internal wave and the oil and gas platform, and the internal wave propagation speed.

[0063] Furthermore, in the above step S23, the time when the internal wave is expected to reach the oil and gas platform is obtained by dividing the distance from the oil and gas platform by the internal wave propagation speed.
