Fault self-rescue system for remotely operated underwater vehicle

Abstract

The invention discloses a fault self-rescue system for a remotely operated underwater vehicle (ROV). The fault self-rescue system for the ROV comprises a self-rescue device mounted at an ROV body, a detection system and a control system, wherein the self-rescue device comprises an inflation device, a switch device and an air bag; the switch device is arranged near the opening of the inflation device; the air bag is connected to the switch device; the detection system and the switch device are in signal connection with the control system; the detection system sends a fault signal to the controlsystem after the detection system detects that the ROV body is faulty; the control system controls the switch device to operate after receiving the fault signal; and the air bag communicates with theinflation device when the switch device operates. The fault self-rescue system for the ROV adopts an intelligent self-rescue method, and does not need manual operation, thereby improving the self-rescue real-time performance of the ROV and reducing the loss of an enterprise.

Description

technical field [0001] The invention relates to the technical field of underwater intelligent robots, in particular to a fault self-rescue system for underwater robots. Background technique [0002] At present, intelligent underwater robots have become the most important equipment for underwater exploration and operation, improving the range of human underwater operations, and improving the level of human underwater operations. It plays an extremely important role in the development of the ocean. The development cost of an underwater robot is quite high, once the main body loses contact with the mother ship, it will cause huge losses. Therefore, how to quickly grasp the position of the underwater robot and recover it has become an important link in the development of the underwater robot. At present, the self-rescue methods of underwater robots used mainly include sending self-rescue commands through underwater acoustic devices when surface personnel find faults, and dumpin...

AI Technical Summary

Problems solved by technology

[0003] Among the existing self-rescue methods, the reliability of the method of sending instructions by surface personnel is poor, and it is difficult to implement in the case of cable breakage and poor underwater acoustic communication. In addition, there is a certain delay for the operator to find a fault and issue a self-rescue instruction. Self-rescue poor timeliness

The self-rescue method of dumping will lose part of the equipment of the underwater robot. In addition, the development of the underwater robot itself costs a lot, and the way of dumping is too economical.

The method of releasing the ballast, the beacon float and the strong cable is too complicated, which is not conducive to the normal underwater work of the underwater robot. At the same time, adding a strong cable will easily cause the cable to be entangled underwater, and the underwater robot cannot be surfaced.
