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 positioning and deformation of long-distance submarine cables. Including the monitoring host computer; the monitoring host computer is set on the shore and connected to the photoelectric converter; the detection system includes a flexible circuit board, and a number of MEMS module components connected in series through the 485 bus connection line are welded on the flexible circuit board. The components include TTL to 485 bus module and MEMS acceleration sensor module; there is also a four-wire 485 connection port between the 485 bus connection line and the MEMS module components; the 485 bus connection line is connected to the central controller, and the central controller is connected to the electro-optic modulator. The invention can realize the positioning and real-time monitoring of the deformation of the submarine cable, realize the remote real-time positioning and self-checking function of the submarine cable, and can be used to improve the stability and fault repair ability of the submarine cable.

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
