Buoy towing type underwater robot system applicable to non-dynamic-positioning mother vessel

Abstract

The invention discloses a buoy towing type underwater robot system applicable to a non-dynamic-positioning mother vessel. The buoy towing type underwater robot system comprises a wireless communication buoy, wherein the wireless communication buoy moves along with an underwater robot so as to move forwards by virtue of connection of an umbilical cable; the underwater robot transmits the detected data to the wireless communication buoy by virtue of the umbilical cable; the communication buoy transmits the data information to the non-dynamic-positioning mother vessel by virtue of wireless transmission; and when the underwater robot needs to be operated, an underwater robot operator on the non-dynamic-positioning mother vessel issues an instruction and transmits the instruction to the wireless communication buoy by virtue of wireless transmission, and the wireless communication buoy transfers the related instruction to the underwater robot by virtue of the umbilical cable. With the adoption of the manner in the system, the problems brought to the normal operation and safety of the underwater robot due to instability of the non-dynamic-positioning mother vessel and great fluctuation are solved, and the biggest obstacle of performing seabed operations by the underwater robot based on the non-dynamic-positioning mother vessel can be avoided.

Description

technical field [0001] The invention relates to an underwater robot control system, in particular to a buoy towed underwater robot system suitable for a non-dynamic positioning mother ship. Background technique [0002] At this stage, large-scale underwater robots are carried on the dynamic positioning mother ship in the process of seabed operations. The dynamic positioning mother ship uses its own propulsion device to keep the ship in a stable and predetermined motion trajectory, so as to cooperate with the underwater robot on the seabed. Do your homework. However, the cost of dynamic positioning ships is high, and the cost of renting and mobilizing them is high, and they are only in the hands of some large-scale units, so the shipping schedule is tight. [0003] Non-dynamically positioned mother ships are widely used, with relatively low cost and low rental costs. There are also many types and quantities of ships available in the market, and they are flexible to use. Env...
