Image recognition monitoring system for preventing ship touch in offshore oil tanker transportation operation

Abstract

The invention discloses an image recognition monitoring system for preventing ship touch in offshore oil tanker transportation operation. The system comprises a visible light collector, a thermal imaging collector, a laser ranging collector, a cable, a junction box, a server and image recognition monitoring software. The server is installed in a control room of a floating production oil storage and discharge device, and the image recognition monitoring software and a database are installed in the server; an early warning discrimination algorithm module is arranged in the image identification monitoring software; the visible light collector, the thermal imaging collector and the laser ranging collector are arranged at the tail part of the floating production oil storage and discharge device; the image recognition monitoring software is used for realizing intelligent recognition of the oil extraction wheel; meanwhile, the image recognition monitoring software inputs intelligently recognized oil extraction wheel information into an early warning discrimination algorithm; according to the early warning discrimination algorithm, the collected and recognized oil extraction wheel information is compared with parameters input in advance, and the installation compensation value of the collector is combined to calculate the hull shape of the oil extraction wheel so as to carry out geometry contact judgment.

Description

technical field [0001] The invention belongs to the technical field of ships and marine engineering, in particular, it is an auxiliary monitoring system for the high-risk operation from the floating production device to the oil tanker. Background technique [0002] Offshore floating production storage and offloading unit (FPSO) is a major equipment for offshore oil and gas development, integrating production, storage and offloading functions. The floating production, storage and offloading unit is anchored in the offshore oil field and has no power itself. When the crude oil fills the oil tank, another oil picker needs to sail to the vicinity of the floating production, storage and offloading unit to transfer the crude oil. Enter homework. [0003] During the export process, the tail of the floating production, storage and offloading unit is connected to the bow of the oil picker through the export cable, and the stern of the oil picker is connected to the tail of the tugbo...

Problems solved by technology

[0006] In recent years, there have been inventions similar to ship identification and monitoring and early warning, but the principle is different from the present invention: if other inventions use the Global Positioning System (GPS) and Ship Identification System (AIS) to track the ship track, but because the positioning accuracy is limited by the satellite Influenced by movement, at the same time, the main engine of the oil tanker is not working during the export period, and is in a non-navigation state, which greatly reduces the accuracy of the heading angle output by the global positioning system, so the results given can only be used for qualitative judgments, according to the Pythagorean theorem It can be seen that the length of an oil tanker is about 220 meters. Assuming that the stern is the axis (because the mooring point of the tugboat is at the stern during work), the bow swings 3.8 meters for every 1 degree of deviation in the course angle. The working length is about 80 meters, and the swing amount is 4.75% of the cable, which has a great influence on the pulling force

[0007] In China, there is an invention similar to the high-precision differential global positioning system (DPGS) to increase the observation accuracy, but for the same floating production, storage and offloading device, the oil picker that comes to provide oil pick-up service is not fixed every time, and the differential positioning The system device needs to be stored on the floating production storage and offloading device. Every time the oil tanker comes, it must be transported, installed and calibrated. After the work is completed, it must be dismantled. The work process is cumbersome and the operation is inconvenient
