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...
