Description

Short baseline location matrix fixing device

Technical Field

The application relates to the technical field of short baseline positioning, in particular to a short baseline positioning matrix fixing device.

Background

The existing AUV (underwater robot), ROV (remotely controlled unmanned vehicle), diving equipment and other underwater equipment are precisely positioned, and a short baseline or ultra-short baseline positioning system is mostly used, and the main functional equipment is a short baseline and ultra-short baseline positioning matrix. As shown in fig. 1, the positioning matrix 100 mainly includes a communication cable interface 101, a signal receiving element 102 and a signal transmitting element 103.

The positioning working principle is as follows: the signal transmitting array element 103 of the positioning array 100 transmits sound waves, after touching a response beacon fixed on the surface of the underwater equipment, the sound waves are reflected to the signal receiving array element 102, at the moment, the signal receiving array element 102 receives echoes reflected by the response beacon, signals are transmitted to an upper computer on the shore through a communication cable connected to the communication cable interface 101, and the upper computer analyzes the three-dimensional position data into visual observation and displays the three-dimensional position data in display control software.

The positioning matrix 100 needs to be fixed in water when in use, and needs to be fixed at a certain depth in water, and keeps stable under water, the signal receiving matrix element 102 needs to keep a certain fixed angle with the geomagnetic field unchanged, and does not displace along with water flow as much as possible, so that deviation of positioning information is avoided, and positioning simulation image distortion is avoided.

The conventional apparatus for fixing a positioning matrix mostly adopts a simple structure as shown in fig. 2, by erecting a horizontal support 201 substantially parallel to the water surface on the shore and vertically installing a vertical support 202 at a portion of the horizontal support 201 near the water to support the horizontal support 201, then placing a long rod 300 on the horizontal support 201, and hanging a vertical rod 400 at an end of the long rod 300, and then installing the positioning matrix 100 at a portion of the vertical rod 400 located in the water.

In the conventional device for fixing a positioning matrix, the depth and angle of the installed positioning matrix 100 cannot be basically adjusted after being fixed to the vertical rod 400. If the vertical support 202 is disturbed by water impact, foreign object impact, etc., sagging occurs, which results in tilting of the horizontal support 201, variation in depth and angle of the positioning matrix 100, deviation in positioning information, and correction at this time is necessary. However, in the prior art, the vertical rod 400 needs to be detached to adjust the positioning matrix 100, or a diver enters the water to readjust and fix the positioning matrix 100, if the inclination is serious, even the horizontal support 201 and the vertical support 202 need to be rebuilt, the adjustment process is very complicated, and if the depth and the angle of the positioning matrix 100 after adjustment are not suitable, fine adjustment is inconvenient again.
