Due to the limitation of early-aged underwater engineering equipment, submarine cables laid in early days are almost laid on the seabed in an open laying mode, corresponding protective measures are not applied, and the submarine cables are easy to be damaged by natural environment and human activities.
The submarine power cable needs regular maintenance after operation, and due to the limitation of human body functions and diving equipment, the submarine cable operation and maintenance operators are difficult to dive to the water bottom below 40m to check and maintain the operation working condition of the submarine cable.
In recent years, as the reliability, stability and safety of underwater robots are improved, it is possible to perform operation and maintenance inspection and fault detection on submarine cables by using unmanned underwater robots. An unmanned underwater robot is also called as an unmanned underwater vehicle, is an unmanned robot system which works under water for extreme operations and can work under water for a long time instead of manpower in a high-risk environment, a polluted environment and a zero-visibility water area. Unmanned underwater robots are generally classified into two major types, cabled remote-control underwater robots and autonomous underwater robots. The greatest difference is that the ROV is connected with the surface mother ship through an umbilical cable to realize energy supply and signal quick transmission, so that an operator can see real-time underwater pictures or other detection data shot by the ROV through a surface mother ship monitor and control the underwater navigation of the robot.
Current underwater robot does not all carry out cleanness and prosthetic function to the cable, and the cable is after long-time laying, and the cable can be covered with debris such as coral or marine alga on the surface for the condition on cable surface can't be seen clearly in direct shooting, thereby influences detection quality, and after the outside that detects the cable appears the crack or corrodes simultaneously, current robot can't carry out effectual restoration to it.
