High-precision real-time monitoring system for long-distance submarine cable positioning and deformation

Abstract

The invention relates to the technical field of ocean observation, in particular to a high-precision real-time monitoring system for long-distance submarine cable positioning and deformation. The high-precision real-time monitoring system includes an upper monitoring computer. The upper monitoring computer is located on the shore and connected with a photoelectric converter. The monitoring systemincludes a flexible circuit board, a plurality of bunchy MEMS module components serially connected through 485 bus connecting lines are welded on the flexible circuit board, each MEMS module componentinclude a TTL to 485 bus module and a MEMS acceleration sensor module, four-wire system 485 connectors are also provided between the 485 bus connecting lines and the MEMS module components, the 485 bus connecting lines are connected to a central controller, and the central controller is connected to an electro-optic modulator. The high-precision real-time monitoring system can realize real-time monitoring of positioning and deformation of submarine cables and remote real-time positioning and self-checking functions of the submarine cables and can be used for improving the stability and faultrepair ability of the submarine cables.

Description

technical field [0001] The invention relates to the technical field of ocean observation, in particular to a high-precision real-time monitoring system for positioning and deformation of long-distance submarine cables. Background technique [0002] "Key technology of marine intelligent pipe and cable" is a frontier hotspot in the field of international marine intelligent technology and equipment research and development, and it is also a technical bottleneck restricting my country's offshore resource development and energy information transmission. With the rapid rise of my country's new energy industry and its extremely rapid development momentum, it has provided a huge market for submarine umbilical products. At present, submarine pipe cables are mainly used in two fields, one is offshore power transmission, and the other is offshore oil drilling platforms. In recent years, the great development of domestic and foreign offshore wind power markets has driven the demand for...

Problems solved by technology

However, this invention is mainly aimed at the monitoring of underwater terrain deformation, and is not suitable for monitoring submarine cables, and the sensor array uses a stainless steel rectangular tube plus a rubber flexible joint structure, which has poor reliability, and the joints are easily damaged, and there is a probability of distortion. MEMS The attitude sensor adopts a 9-axis attitude sensor, which has relatively high energy consumption and is not suitable for long-term underwater deployment
