Problems solved by technology

[0002] During the salvage process, divers often encounter relatively low visibility and permeability of the surrounding environment due to sediment, sewage and sediment. Difficult, the low-visibility environment restricts the use of light sensors, and divers cannot observe the underwater environment with the naked eye
At the same time, due to the low visibility, the diver's field of vision is dark, causing the diver's sense of insecurity and great psychological pressure.

Abstract

The invention discloses a sound two-dimensional array sensor including a sealing housing, the sealing housing is provided with a sonar signal transmitting device, an acoustic lens, a light source, a two-dimensional array fiber sensor, and a processor, the sonar signal transmitting means is used to transmit the sonar signal, the sonar signal is reflected by an obstacle and then is focused on the two-dimensional array fiber sensor through the acoustic lens to obtain an electric signal, and the electric signal is transmitted to the processor for processing to obtain the image information of the obstacle. The sound two-dimensional array sensor can effectively observe the underwater environment of turbid water areas, improve the activities of underwater divers, and ensure the safety of the divers.

Description

technical field [0001] The invention belongs to the technical field of underwater environment observation devices, in particular to an acoustic two-dimensional array sensor. Background technique [0002] During the salvage process, divers often encounter relatively low visibility and permeability of the surrounding environment due to sediment, sewage and sediment. Difficult, the low-visibility environment restricts the use of light sensors, and divers cannot observe the underwater environment with the naked eye. At the same time, due to the low visibility, the diver's field of vision is dark, causing the diver's sense of insecurity and great psychological pressure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an acoustic two-dimensional array sensor, which can effectively observe the underwater environment in turbid waters, improve the activity ability of underwater divers, and ensure the life safety of diver...
