Underwater long-distance tunnel signal local transmission system and method

Abstract

The invention provides an underwater long-distance tunnel signal local transmission system and method. The system comprises an AUV body, a plurality of signal transmission carriers, a signal transmission parent body, an overwater control platform and a working ship. The overwater control platform is arranged on the working ship, and the signal transmission parent body is connected with the overwater control platform through an umbilical cable; the AUV body is provided with a mechanical claw and is used for carrying signal transmission carriers into an underwater tunnel, and the signal transmission carriers are sequentially arranged in the extending direction of the underwater tunnel at intervals; the AUV body, the signal transmission carrier and the signal transmission matrix are respectively provided with a signal receiving module and a signal transmitting module; the AUV body is an underwater robot without a cable, and the signal transmission matrix is an underwater robot with a cable. The signal transmission carriers are arranged in the underwater tunnel at certain intervals, so that the signal transmission capability of the AUV body in underwater operation is improved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, in particular to an underwater long-distance tunnel signal local transmission system. Background technique [0002] As we all know, water conservancy and hydropower projects have been widely developed and applied in my country. Hydropower stations, as the main hydraulic structures for the development of clean energy, deliver water through diversion tunnels to turbines to drive generators to rotate to generate electricity. The water delivery function of the diversion tunnel is very important in the process of hydroelectric power generation. The performance of the tunnel structure is related to the water delivery pressure of the pipeline and the safety of the water delivery process. With the long-term use of the completed hydropower station, the internal inspection and evaluation of the tunnel structure has become an indispensable content. The detection schemes...

Problems solved by technology

The untethered underwater robot is separated from the load of the umbilical cable, and the range of operating capabilities has been greatly improved, but the biggest problem is that it cannot realize fine fixed-point detection and operation, mainly because the distance of the underwater tunnel is long, and the signal transmission is weak or lost , unable to communicate with the supporting mother ship in a timely manner to transmit data information in real time, and the control technicians cannot make timely predictions, which may cause the signal of the underwater robot to be disconnected and cause the loss of machinery and equipment, which not only causes equipment economic losses but also damages the tunnel structure. security poses certain hidden dangers
