Description

Surveying system for seawater road by sound exploration

The present invention relates to a terrain change surveying system of a sea channel by acoustic (sound wave) exploration. In particular, the sound wave output device which is fixedly installed on the sea floor and is semi-permanently operated through self-power generation is distributed and installed on each sea floor. Surveying terrain changes to sea channel by acoustic exploration by classifying and receiving signals for each sound wave output device so that the state of topographical change on the bottom of the sea can be relatively accurately analyzed through analysis of data with continuity over a relatively long period of time. It is about the system.

In general, when performing fishing work, construction of marine buildings, military operations, and port operations in the ocean, information on the seabed topography is obtained using paper, electronic charts, and various electronic observation equipment.

To this end, the most widely used method so far is to obtain information about the seabed topography, such as the sea channel by using a sound wave detector or a sound detector.

However, in the conventional method of acquiring information about the seabed terrain using such a sound wave detector (sound detector), a sound wave detector is installed in the ship to send sound waves toward the sea floor near the sea surface and then receive sound waves reflected from the sea bottom. It is a method of obtaining necessary information, and the exploration work is disturbed by waves of sea level and reflection of sound waves of fish or aquatic organisms, and accordingly, it takes a long time and repeats Failure to obtain information often presents a difficult problem.

In addition, in order to acquire the data on the topographical change of the seabed terrain relatively accurately, it is necessary to repeat the transmission and reception of sound waves at a relatively constant position with respect to the seabed terrain, but the conventional method of obtaining information on the seabed terrain through the sound wave detector of the ship Only ships move to the exploration position and return to the port after the exploration, so it is not easy to send sound waves by placing the sonic detector at the same position as the previous exploration based on the exploration of the same seabed terrain. As a result, it was not easy to obtain change data of the seabed topography.
