Online internal wave early warning system and method

Abstract

The invention provides an online internal wave early warning system and method. The system comprises a water surface mobile platform composed of a plurality of sets of wave gliders and an underwater mobile platform composed of an underwater autonomous vehicle, and the water surface mobile platform and the underwater mobile platform carry out networking cooperative operation and advance according to a pre-planned cruise route or an anchoring scheme. The wave glider is flexibly connected with a towed body, and the towed body is used for collecting first data and processing the first data, and is also used for communicating with the autonomous underwater vehicle, receiving and processing second data of the autonomous underwater vehicle, and determining whether to send an internal wave early warning of a monitored sea area according to a processing result; the autonomous underwater vehicle is provided with a data sensing unit and a communication unit, the data sensing unit is used for collecting the second data of the autonomous underwater vehicle, and the communication unit is used for communicating with the towed body. Long-time cruising operation can be carried out on the sea, internal wave monitoring is flexibly achieved in real time, and the three-dimensional and long-endurance targets of ocean observation are achieved.

Description

technical field [0001] The invention relates to the technical field of online internal wave early warning, in particular to an online internal wave early warning system and method. Background technique [0002] Ocean internal wave is a kind of fluctuation that occurs in seawater density stratified ocean. It is one of the common disastrous marine environments. It threatens the stability of semi-submersible and anchored oil platforms, and affects the offshore operations such as drilling and riser installation. manipulation. Therefore, the real-time online early warning of internal waves is of great significance to the implementation of marine engineering, which can broaden the operation window as much as possible while reducing the operation risk. [0003] Although the current online monitoring schemes for internal waves have realized the monitoring of internal waves to a certain extent, they mainly focus on the observation of the structure and dynamic process of internal wav...

Problems solved by technology

[0003] Although the current online monitoring schemes for internal waves have realized the monitoring of internal waves to a certain extent, they mainly focus on the observation of the structure and dynamic process of internal waves, and the real-time performance is insufficient; there are also some monitoring methods that use buoys as carriers to monitor Observing ocean parameters and then analyzing the data to obtain internal wave early warning information, this method is limited by the characteristics of buoys, and can only carry out early warning at fixed points, and cannot flexibly change the monitoring position according to changes in the marine environment during construction operations

[0004] Therefore, there is a lack of a real-time, mobile and flexible online internal wave early warning system and method in the prior art
