Problems solved by technology
[0003] When using ROV to carry out deep-sea operations, it is often necessary for the ROV umbilical cable winch to release the umbilical cable thousands of meters long. The length of the umbilical cable released is determined according to the detection needs. The maneuverability and energy efficiency of ROV may even cause the umbilical cable to be entangled, knotted or dragged by foreign objects, which not only leads to the failure of the operation task, but also fails to recover the ROV and umbilical cable normally; Will limit ROV navigation maneuvers and underwater operations
At present, the length data of the released umbilical cable can only be roughly estimated by the number of turns of the drum of the ROV umbilical cable winch. The position and attitude state is very complex and changes at all times, so it is impossible to accurately predict and simulate, and there is no effective monitoring system that can realize real-time and accurate monitoring of the cable shape and position of the umbilical cable. Therefore, the ROV umbilical cable winch The operation of the umbilical cable winch is a complicated job, and several professionally trained operators must be equipped. The professional operators will manually control the ROV umbilical cable winch according to the instructions and status of the ROV, combined with subjective experience. Large and highly subjective, it often leads to problems such as too long or too short cables, and there is a large risk of misjudgment and misoperation
At the same time, this manual control method has high operating intensity, low control efficiency, high operating cost and low degree of automation.

The invention discloses a system and method for monitoring automatic cable winding and releasing of an ROV (Remotely Operated Vehicle) umbilical cable winch, and relates to the field of marine engineering systems and equipment. The system comprises a water surface mother ship, a remotely operated vehicle (ROV), a control console, an ROV umbilical cable winch, an umbilical cable, a sound source, optical fiber hydrophones and an acoustic beacon, and is characterized in that the control console, the ROV umbilical cable winch and the sound source are arranged on the water surface mother ship, the sound source faces towards the underwater, the control console is connected with the ROV umbilical cable winch and the sound source, the ROV umbilical cable winch comprises a winding drum, one end of the umbilical cable is wound on the winding drum of the ROV umbilical cable winch and is connected with the control console, the other end of the umbilical cable is connected with the ROV, the optical fiber hydrophones are arranged on the umbilical cable at intervals, and the acoustic beacon is arranged on the ROV. The system can perform online monitoring on the states such as the cable shape and the cable length of the umbilical cable underwater, can realize three-dimensional simulation display for the underwater position states of the umbilical cable and the ROV through comprehensive analysis and processing and improves the manipulation intuition and the system security.
Description
technical field [0001] The invention relates to the field of marine engineering systems and equipment, in particular to an automatic retracting and unwinding cable monitoring system and method for an ROV umbilical cable winch. Background technique [0002] Unmanned cable control submersible (Remotely Operated Vehicle, referred to as ROV) is an important equipment in deep sea exploration and operation. It is usually deployed and recovered by the ROV umbilical winch on the surface mother ship. The ROV umbilical winch is used to realize Retractable cables, row cables and storage cables, while the umbilical cable connects the surface mother ship and ROV, and plays an important role in ROV power transmission and data communication. [0003] When using ROV to carry out deep-sea operations, it is often necessary for the ROV umbilical cable winch to release the umbilical cable thousands of meters long. The length of the umbilical cable released is determined according to the detecti...
