Underwater pipeline detecting and tracking device with autonomous remotely operated vehicle

Abstract

The invention discloses an underwater pipeline detecting and tracking device with an autonomous remotely-operated vehicle. The underwater pipeline detecting and tracking device comprises a lower computer and an upper computer, the lower computer is arranged below the water surface, the upper computer is arranged on a water surface mother ship; the lower computer comprises a sensor module, an optical vision module, an embedded controller and an underwater optical transceiver, wherein the sensor module and the optical vision module are correspondingly connected with the signal input end of the embedded controller, and the signal output end of the embedded controller is connected with the signal input end of the underwater optical transceiver; the upper computer comprises an overwater opticaltransceiver, a water surface monitoring module and a hand controller, the hand controller is in circuit connection with the water surface monitoring module, the water surface monitoring module is incircuit connection with the overwater optical transceiver, and the underwater optical transceiver is connected with the overwater optical transceiver through an optical fiber. According to the device,the autonomous remotely-operated vehicle can achieve real-time image transmission, the water surface mother ship can monitor the underwater environment in real time, so that the safety of the complexunderwater operation condition is ensured, and the detecting and tracking task of an underwater pipeline is completed.

Description

technical field [0001] The invention relates to the field of submersible detection, in particular to an autonomous remote-operated vehicle (Autonomous Remotely-operated Vehicle, ARV for short) underwater pipeline detection and tracking method and device. Background technique [0002] The ocean is a new field for human survival and sustainable social development. The development and adoption of the ocean has become one of the basic factors that determine the rise and fall of a country. According to relevant information, since my country officially exploited offshore oil and natural gas, dozens of oil and gas pipelines thousands of kilometers long have been laid on the seabed. Due to long-term corrosion of seawater pipelines under high pressure, as well as material quality, fatigue, crustal changes, anchor chain dragging and other reasons, many submarine pipeline damages and oil and natural gas leakage accidents have occurred in the world, causing huge economic losses. and se...

Problems solved by technology

The disadvantage is that due to the limitation of underwater acoustic communication, real-time image transmission cannot be realized. AUV is completely dependent on its autonomous capabilities. The surface mother ship cannot monitor the specific underwater environment in real time. It is unsafe for complex underwater operations and prone to AUV loss. Happening
